It seems like LiveCode's text search routines would make it pretty easy to delimit the various attachments from each other. The hard part would be deciding what to do with them once you had them. len morgan ___ use-revolution mailing list use-revolution@lists.runrev.com Please visit this url to subscribe, unsubscribe and manage your subscription preferences: http://lists.runrev.com/mailman/listinfo/use-revolution
Re: on-rev remote database
This is all a moot point now since I have just been informed by Heather that the only way the on-rev server can be set up to do this is if you give them all of the IP addresses that people are going to connect from and they will allow those IP addresses to connect. This of course will never work with a large potential user base of hundreds or thousands. I guess I'm going to have to throw away everything I've done so far and start over with the web based approach that Pierre suggested. It's going to kill my performance but it's the only option I've got open to me at this point. len morgan On 10/19/2010 2:27 AM, Pierre Sahores wrote: Le 18 oct. 2010 à 20:41, Andrew Kluthe a écrit : The client never actually gets the login credentials for the database because they are stored in our private big client DB.

Re: on-rev remote database
I appreciate everyone's concern about about the security of my database but I assure you that this isn't my first rodeo (small 'r' - not a plug :-) ) and have been write secure computer systems for prison management for over 10 years - most of them with remote access. I should probably elaborate a little more on what I'm attempting to do. The data I'm trying to give access to is already publicly available to anyone one the Internet. It's just not organized in a way that can be searched, sorted, what have you. The data (and the service) are all available on a web site but while the site provides all the necessary facilities to do what you need to do, it doesn't do it in any kind of user friendly way. My program is composed of two parts: The first is twice a month, I download the web page with the information on it, scrape the data out of it, and then post the NEW data (about 30% is new) to a database. I also add the date that the listing showed up for the first time. The second part of the program is used by the end user who will log in, get only the newest listings that pertain to him/her and then decide if they want to submit to one of the listings. If they do, they'll choose the data to upload and having already entered their username and password for the original site (which they must already be a paid member of) I'll pretend to login, go to the submissions page, and make the submission. Once this is done, they will have local database of their submissions that includes the deadlines (so they know when to check and see if their submission sold or not), etc. The reason I don't want the database of listings stored locally is because every now and then, they change the format of their listings page and then my scraper stops working. Instead of having to update hundreds of users, I store MY version of the database the same way no matter what the source data looks like. I have to do a little work to figure out the new format but only once. It also tends to be a rather large database and having that lay around on everyone's computer seems like a waste. Now I hope you can see why I wasn't that worried about the security of the data. It was read only, already publicly available, and you had to already be a member of the other site (not mine by the way) in order to do anything useful with the data. I do want to thank everyone for their suggestions though. I enjoyed the discussion. len morgan On 10/19/2010 12:59 PM, Richard Gaskin wrote: Whiskey Tango?

Unless I missed something earlier in this thread, it seems he's writing about blocking access based on IPs, and all Heather did was remind him of what Pierre wrote here, that given the majority of folks who use dynamic IPs that isn't practical. FWIW, On-Rev does indeed provide unlimited databases: MySQL 5.0.67 Databases: Unlimited PostgreSQL Databases: Unlimited http://www.on-rev.com/hosting/features-chart/ Back to the original topic, granting/restricting access based on IPs is risky and prone to error if any of your users have dynamic IPs, for the reasons Pierre noted earlier this morning. IP-based restrictions can be somewhat useful for some institutional customers where fixed IP ranges can be known to belong to the customer. I use it myself on a subscription site I manage for a client, but not as an alternative to login authentication but merely as an extra restriction on top of the login requirement; I would never rely on IP address alone. With individual users on dynamic IPs, the risk is that the IP they're using right now may be reassigned to someone else later, providing unauthorized access to unknowable individuals. Granting access by range only exacerbates the risk. So while it's sometimes useful, IP-based access doesn't appear to be a practical option for Mr. Morgan, leaving him to consider more conventional options like a simple login as most sites require for authenticated access. Andrew, you can hopefully breathe easier now.

Re: on-rev remote database
Pierre, It's only a security risk if I let the users WRITE to the database which I have no intention of doing. The reason I'm trying to avoid and irev script in the middle is that I don't want to have to connect and disconnect every time a user asks for data. If you have a sample irev script that would allow several hundred (I hope) users to read from this database, I'd love to see it. Maybe it's not as bad (i.e., establishing a new connection to the database every time) as I'm thinking.

Re: Socket read problems
Dar, I wish it was that simple but the length of the message is only in one byte so it's pretty hard to swap. For test purposes, I have scrolling field where I print the progress of the conversation and I am displaying the correct length. Also, I've got WireShark on the line so I can look at the actual packets to make sure I'm picking the right bytes, etc. and all of that is ok. The only thing that seems out of place is that there is one more zero byte at the end of payload that fills out the data area to an even word boundry. This null byte is not part of the data and is not counted in the length byte that I'm reading. I believe that is part of the TCP/IP spec but it's been a long time since I've done a digital colonoscopy on network protocols so I could be mistaken. What ends up happening is that the socket read command is getting one more byte than I've asked for so I'm wondering if it hangs up when I try and close the socket since I still have one unread byte in the buffer. As it turns out, if I try and read that extra byte too, the result is the same: The read command will not finish until socketTimeoutInterval milliseconds have passed yet is never sends me a socketTimeout message. The particular slave I'm talking to is from a major commercial vendor (inventor of ModBus as a matter of fact) but as I recall, my own slave (built with an Arduino) suffered the same problem. Is it possible that since I'm not using the callback on the read complete, that there is a bug in the read socket library? I will do some more experimentation today and report back what I find. I will also try and whip out a LiveCode slave and see if I can make it do the same thing on the same machine. That should be interesting. len morgan On 10/8/2010 12:42 AM, Dar Scott wrote: Could you have gotten the two length bytes swapped and are asking for way too many bytes?

Re: Socket read problems
Dar, As it turns out, (and much to my embarrassment) you were close on your first response: I was trying to read more bytes than were actually there. The ModBus/TCP spec actually sends two length items. One is the header + data length and the other is the data length only. What I was doing was reading the former, then getting the actual data length, then trying to read that many MORE bytes when I already had the data and header in a variable. It still bothers me though that I never got the socketTimeout message even though that's exactly what was happening. len morgan On 10/8/2010 11:45 AM, Dar Scott wrote: On Oct 8, 2010, at 5:29 AM, Len Morgan wrote: I wish it was that simple but the length of the message is only in one byte so it's pretty hard to swap. Yeah, I guess the high byte is always zero. I never use read by number of bytes. It is not that I have seen problems with it, I just became comfortable doing things another way. I usually use 'read from socket with message callback'. I don't think the 'with message' is important for the behavior I see. This reads whatever is in the buffer. I think some people use an idiom of for 0 in the command for this. I collect bytes into a buffer until there is a whole message and then pull that off, in a sense, doing myself what you are looking for LiveCode to do. You might be able to use 'read from socket' as a way to prevent the timeouts and to diagnose the problem. This will show if there are problems with the frame length.

Is this possible? Also, can the lines in an option (or combobox) list be colored differently for each item or will I have to hand craft something like that?

Getting Property Names

Data Grid Column Header Problem
I had this problem once before but I can't find the solution to it now. What's happening is I have a lot of information to show in a DG table (lots of columns). In order to make it all fit, skinny columns like Sex and Age have been abbreviated to S and A respectively. The problem is that there appears to be some sort of border around the column headers so that I can only see a few dots from the middle of those two characters in the header making them unreadable. I tried changing the header margins but that just moves the text in the header up. How can I get rid of the blank space on either side of the column header text? Thanks in advance!

Re: Data Grid Column Header Problem
Len, The ideal min size is 40. I gave your problem a try. It seems to me that the content of your columns is centered. In this case, changing the margins with the header margins do nothing, because the field displaying the header title has a width of 2 pixels. If you can give 10 more pixels for those two columns, all will be ok. Otherwise, for now I don't see any workaround. Regards, Ideal according to who? Is that a Rev limitation or part of the Data Grid? It seems to be awfully large. I did expand those columns (and reduced the width of another to make them fit) so it's all working now. It sure would be nice if we could lower that limit though. len ___ use-revolution mailing list use-revolution@lists.runrev.com Please visit this url to subscribe, unsubscribe and manage your subscription preferences: http://lists.runrev.com/mailman/listinfo/use-revolution
Adding configuration (by username) to a stack
I have an application that's been out in the wild for about 3 years now and the customer is asking for some updates. One of the items that they want to change is adding the ability to do certain things like delete records (currently they call me and I do this remotely) but they only want to have certain people, based on the name they log in with, to be able to do it. I've been toying around with several different methods but I'd really like some advice on what might be the best way to make these changes to a well established program. What I'm going to need to do is: Have certain menu items either disabled or removed based on the user's rights. Have some buttons on various cards either disabled or invisible. Have certain pop up stacks come up in either read-only or read-write mode. I would like to have a system of profile stacks (this seems the most manageable to me), one for each role. I already validate their login from a database and get a profile description (like Administrator) and a profile name (like admin) for each user but I've never done anything with them. Any suggestions or pointing of the way would be appreciated. len morgan ___ use-revolution mailing list use-revolution@lists.runrev.com Please visit this url to subscribe, unsubscribe and manage your subscription preferences: http://lists.runrev.com/mailman/listinfo/use-revolution
Re: Rev standalone app stays in memory on my Xubuntu 9.10

Open the dictionary, and in the panel at the left under the Objects category, click Button. That lists all relevant button info. I wish this were so but while there are some messages there, many are missing. For example, I'm not sure why socketClosed is listed under Object-Button but mouseUp is not. The messages entry does have mouseUp but doesn't tell me it's sent to buttons. What I guess I need is all of the entries from the messages category that apply to buttons (for example). Is there a way to get this? It would be really cool if I could get any handlers along the way like in groups, cards, stacks that this button (or whatever control for that matter) is contained in/on. The message hierarchy only works in one direction, starting from the object that first receives the message and moving on toward the engine. That means that you can't easily retrieve messages sent to an object farther along the hierarchy unless you specifically use a send command to re-route it, or insert a frontscript to catch it before anything else does. Behaviors are the single, limited exception; they push a message backward to a subscribing object, but after that the message goes through the hierarchy normally. I think you might have misunderstood what I was asking for here. What I was suggesting was a way to map a message from, for example, a button to a group to a card to a stack to a library to the engine (with maybe a front and back script if appropriate). I guess it wouldn't be too hard to cobble something together that worked like traceroute does (tracert for Windows users), and get the long ID of a control, get a list of the messages in it's script, then for each message, send the message to the next object in the long ID (group, card, etc) and see if I get an error.

Custom Control Design Tutorial
Has anyone created a tutorial for creating and using a custom control? What I'd like to end up with is a custom control that I could copy onto a stack similar to Trevor's Data Grid. As an example, I've been tasked with redesigning the GUI for a pipeline control system that comprises various tanks, pumps, valves, etc. and I'd like to just create one of each and be able to put multiple instances on a page (the system currently uses 6 HUGE monitors hung on the wall of the control room). To the a water tank as an example, it needs the following: It needs to look like a water tank (cylinder of varying hieght) with water in it that goes up and down to reflect the amount of water that is actually in the tank. A number to show the current level (in feet) that is in the tank. Some parameters like tank height, spill height, minimum level with an alarm if the level goes below it. A visual indication that it is spilling or has gotten too low. I created a little stack and I can do this graphically and I can set variables like currentTankLevel and have it change the number and the water level but it's not portable so I guess what I'm asking is if there is a tutorial that can tell me how to take this one-off widget I've created and turn it into a custom control/widget that I could copy on to a stack and then set up to make that instance unique? I know it will probably need behavior scripts and such, and I'm pretty sure all the pieces to do this are laying around in the mail archives somewhere but I was hoping that there was some sort of a step by step guide.

Re: Custom Control Design Tutorial
Maybe *I'm* the one that's misinterpreted the question! :-) I think what you're telling me is that I'm over engineering the problem and that all I'm really after is a self-contained group that has all of the functions I'd need to manipulate the tank which I would then copy (or clone?) as many times as I needed to get the required number of tanks. I guess in the end, a Data Grid is nothing more than a group. This actually brings up another question though: There are some cases of tanks in the current system that display the feet of water in the tank next to the tank, and some where the number is shown IN the tank. If we temporarily ignore how I'd let the user move around the component parts of a tank (assuming I'd let them), what are the locations of the components in the group (i.e., oval and rectangle for water graphic, text box for numeric level, etc) telling me? Are they the physical locations on the screen at that instant or are they (or can they be) relative to the location of the group as a whole? len morgan On 3/27/2010 9:18 AM, Björnke von Gierke wrote: I'm not sure what would make your object not be portable? the main things to look out for are: Changing the rectangle or location will of course change some movement dependant scripts. you need to look out for that if you do graphical stuff (like resizing a water level graphic for your tank). Use a group, and set its lockLoc to true. Generally It's easier to handle various objects that belong together if they're grouped. Keep your scripts together. Group all objects that belong to your custom object, and move all toplevel scripts into that group's script. Try to keep all custom properties in that group too, so that you have one place to go to for setting stuff and calling scripts. To be able to identify the correct object when there's several on one card, I suggest to change the groups name to something unique. Beyond that, there's really no additional measure to take, unless I misinterpreted your question.

Re: socket write/read conflict?
I stand corrected on the comma. I don't know where I got the idea tab was the default. As to the sockets getting confused, this can't really happen since socket is defined by both the server and client IPs AND server and client port numbers. Unless you've got more than one machine with the same IP, each socket would be unique even if all the clients were talking to the same server on the same port. To take a page from Jerry Daniels (of tRev fame), perhaps you can simplify this by making it a little more complicated. Unless I misread your original post, you want to know who answered first in addition to the actual answer. As each answer comes in, why not just grab the seconds each socket either opens or receives data until all have answered. Then you can see who had the lowest seconds (first response), and then read each answer and check for correctness. This takes the time pressure and allows you to better coordinate the response. len morgan On 3/22/2010 11:10 PM, Nicolas Cueto wrote: Thanks for replying, Len.

Re: Still Having Data Grid Row Coloring Problems
Would changing the hilite color do what you need? Not exactly. What I'm trying to do is color each line depending on the contents of a field of the database. This system tracks inmates and they can be either released, in-custody, out-to-court, etc. and each one of these would have a different color so you can see without having to read a field someone's current status. I've used this color coded system for over 10 years and it's quite popular with customers because it requires them to think less. I did test out setting column background colors and the missing piece was setting the opaque of to true. Here is a modified version of the example script: private command SetForeGroundColor if GetDataOfIndex(the dgIndex of me, line has error) then set the backgroundcolor of me to red set the opaque of me to true else set the backgroundcolor of me to empty set the opaque of me to false end if end SetForeGroundColor This worked just like I wanted with one exception which I may not be able to get (and I'm VERY happy with just having the colored lines). You already have a column separator line but it would be much easier to read across (this list takes almost 2/3rds of the screen width) if there were row borders too. Is there some way to get both colors AND row separator lines?

If I change foregroundColor to backgroundColor, as soon as the selection moves off of a line, the whole line becomes invisible (but the data is still there since if I go back to that line with the hilite, the data again becomes visible).

Re: Still Having Data Grid Row Coloring Problems

Re: socket write/read conflict?
Two things jumped out at me in your code: 1) broadcastToAllClients - you show an IP address of 127.0.0.1. If this was not just an example, you can't use that number. That is the IP of the local host and won't actually ever leave the machine. 2) You are selecting item 3 of tArrayDataLine which I assume is comma delimited (based on the example line above it). I don't set a setItemDelimiter to comma in that handler and I /think /the default delimiter is tab. I also believe that the itemDelimiter you set is only valid for the current handler so as soon as this handler is finished, it will revert back to tab. Hope that helps a little. len On 3/22/2010 10:14 PM, Nicolas Cueto wrote: Hello List, I've made a quiz-type game where 2-6 students on client stacks buzz in their answers to a server stack, all on a local network.

Still Having Data Grid Row Coloring Problems
I'm still not able to set the background color of an individual row in a data grid. Well, that's not entirely true. I can make a row invisible but I can't change it to the color I want. I have followed the instructions in the lesson How Can I Colorize Individual Lines in a Table?, and if I do what the lesson says, it does in fact work but it only changes the FOREGROUND color of the text. I need to set the BACKGROUND color of the text/column and when I do that, as soon as another line is selected, the hilite changes to that new row and the old row is blanked out completely. If I go back and select the now invisible row, all the data comes back (hilited) so the data is still there. Is set the backgroundColor of me to XXX the correct command to use or should I be changing the background color of some other control (like the rectangle that shows up in the column template)? len morgan ___ use-revolution mailing list use-revolution@lists.runrev.com Please visit this url to subscribe, unsubscribe and manage your subscription preferences: http://lists.runrev.com/mailman/listinfo/use-revolution

To answer your first question, the lines aren't getting colored and I have a message that's supposed to print to the message box as it goes by. I went so far as to put a 500 ms delay in this routine (so EVERY column would wait 1/2 a second just in case the message got overwritten by a later message. I'm not sure what you mean exactly by what columns have you defined. They are all text fields, (e.g., no icons, images, buttons, etc). I create the data array by going though the returned data a line at a time and creating a tab (col) delimited, cr (row) delimited variable then use: set the dgText of group searchResults to theDataA To clarify your first comment, if I set the entire data array using dgText, does it call FillInData for every line possible or only the visible ones? The reason I ask is that one of the things I want to do with FillInData is to get three more fields that don't come out of the original query. I have two dates that come out of another table and have not been able to come up with any SQL query that would return these fields in the original query. What I want to do is when FillIndata gets to the first field (key field), I can call another query for that one record only. As each row is processed, I can get these two dates. This will not be a processing burden IF I only fill the data that is on the screen at the time.

More Data Grid Difficulties - Making it request data
I found the manual pages for coloring lines in a data grid table but it's not working. I'm pretty sure that the reason is because I'm settting the dgText to the array I create from the database records and that is bypassing the FillInData routine. I guess what I need to do is only fill in the records when asked for by the data grid. How exactly would I do that? I need to keep the records in the order they come in from the database but once they are in the table, they could be changed as long as I could get back to the correct line number in my variable. I do NOT need to edit any of the data in the grid. It's only purpose is to display a list of people that are returned from a query (made up on the spot based on the fields the user types in). They need to be able to scroll the list (could be as many as 300 names) and they need to be able to double click on a line to select that person. As long as I can get the data from the first column, I can manage the rest (in fact, that part is working fine right now. I read the entire query result in rather than using a cursor so the examples in the data grid manual I don't think are going to help. Is there a way I can: 1) Do the query 2) Convert the results into a tab/return delimited list of records 3) Tell the data grid to start filling in the data and request the line numbers from me I have 1 and 2 done. All I need is a way to tell the data grid to start requesting the visible rows and (hopefully) pass me the line number it wants (which will match up with my line numbers). After that, I think the colorization routines will fire and do their thing.

Anyway, could be that your resized column is not wide enough; at the right side of each header, a space is kept for the arrow icon which shows the sorting direction. If the header is centered, then the column must take this space into account otherwise the header is not entirely visible (seems like shifted to the left) Widening a bit your column should allow you to see the whole text of the header. If this does not solve your problem, could be that a script in the revdatagridlibrary has to be completed (It was the case for my problem) but I prefer that Trevor helps you if such a modification is necessary ;-)) Best regards from Grenoble André ___ use-revolution mailing list use-revolution@lists.runrev.com Please visit this url to subscribe, unsubscribe and manage your subscription preferences: http://lists.runrev.com/mailman/listinfo/use-revolution ___ use-revolution mailing list use-revolution@lists.runrev.com Please visit this url to subscribe, unsubscribe and manage your subscription preferences: http://lists.runrev.com/mailman/listinfo/use-revolution
Substacks Editing and Visibility
I was trying to update a stack I wrote a couple of years ago (in my revAdolescence stage) and moved what had been several separate stacks into substacks of the main stack. One of those stacks was a debug stack that I can use to send logging information as the program runs. It is marked as visible but ever since moving it into the mainstack, I can't see it anymore. It is there because using tRev, I can get a snapshot of the stack and it indeed has the information I've been writing to it there. So my first question is: Can you have a separate window composed of a substack of the main window/stack, or are will I have to pull this out as a separate stack file in order to see it? The location looks ok and as I said, the visible property is true. My second question has to do with editing substacks. CAN I edit a substack or do I have to pull it out, edit it, and then put it back as a substack of the main stack? What I'm after in the end is a single (or as close as I can get to it) stack for updating.

Serial Port Woes
I'm having a lot of trouble consistently reading a serial port. I'm trying to talk to a microcontroller using ModBus ASCII and the basic idea is to send a request for data (about 12 bytes) and then wait for an answer (about 300 bytes).

I have to open the com port, send the command, then close the port and reopen it for read to get anything at all. I've tried until linefeed, until empty, until eof, for 1 line, etc. and none of them seem to work reliably.

Rev IDE vs MetaCard IDE
Can someone give me a quick summary of why I might want to use the MetaCard IDE instead of RunRev's? It seems that a lot of users of this group use MC. Is it just what you were used to or is there some feature that Rev's doesn't?

Re: Mac ODBC connection to MSSQL on Windows Server
Mark, If you've got a functional ODBC driver on the MAC it should work just like it was on Windows. At the wire level, it's just talking on sockets. As far as using it in a revLet, it appears all of us that have this need are, shall we say, screwed. You will have to have some sort of .cgi process on a server somewhere that will be able to talk ODBC to the database server and use sockets to talk to the revLet(s). It can be a simple as passing the parameters you were going to pass to the revDB call along with the name of the routine (as text) and then excute this on the cgi end to talk to the real database. It's quick and dirty but should be easy to get up and running. You can make it more robust later if there's a hurry to get something done. Better yet, get after runRev to give us someway to communicate with databases from revLets and the problem will be solved. len Mark Stuart wrote: Hi all, A colleague of mine wants to build a revWeb internet application that accesses data from a MSSQL Server on a Windows server.

lineoffset - In Reverse
I'm trying to parse a file, who's format I have no control over. I have found the pattern that I need but in order to make it work (easily) I need the equivalent of lineoffset to work from the end mark (which I can reliably find) and the start of that section which is a variable number of lines above the end mark. The start of a section is a line by itself with ... but this same line is also used to mark off other sections that I don't need. So, what I need to do is: 1) find the line offset to the next end-of-section marker 2) find the line offset from #1 BACKWARDS to the first line that starts with ... Is there such a function? I can always roll my own and just read lines backwards from #1 above until I find the start mark but why reinvent the wheel if such a function is already in revTalk. len ___ use-revolution mailing list use-revolution@lists.runrev.com Please visit this url to subscribe, unsubscribe and manage your subscription preferences: http://lists.runrev.com/mailman/listinfo/use-revolution
Re: On-Rev and PostgreSQL
The file you'll need to look at (and possibly modify) is the pg_hba.conf file in the directory above where PostgreSQL stores the actual data tables. It is very well commented (you'll want to go near the bottom of the file to see the examples that come with the standard distribution). You are allowed to control access to individual databases by not only username/password but also by IP/domain name, whether it is on a secure connection etc. I'm not sure if the PostgreSQL admin program let's you do that or not. I've been using PostgreSQL since version 1.09 (about 12 years) and so have grown up modifying the files with a text editor. On a similar point though, how would you even get the revdb.dll into the revLet so that it could access ANY database? Since revLets are supposed to be platform neutral, how would it know which dll/bundle/so to load in the browser? Has anyone managed to access ANY database from a revLet? If so, could you provide a short script showing how? I'd really like to use SQL Yoga in a revLet but I haven't figured out this (very basic) little detail. len Trevor DeVore wrote: On Nov 15, 2009, at 8:38 PM, Rick Harrison wrote: Since the people at Revolution say that PostgreSQL should work fine on their On-Rev server I think that perhaps they should be held accountable for their advertising of said capabilities. I imagine PostgreSQL works fine if you connect from localhost. Does the database work if you connect with an .irev page running on the server? Usually a database won't allow a user to connect from a remote server without you explicitly telling the database to allow them to do so. So the question still remains: Has anyone out there been able read and write to a PostgreSQL database on an On-Rev server using a revlet? I haven't tried, but if you are having trouble then I would check whether or not you authorized the user you are connecting with to connect from outside hosts. By default the database user is usually restricted to connecting from localhost only (at least with MySQL). ___ use-revolution mailing list use-revolution@lists.runrev.com Please visit this url to subscribe, unsubscribe and manage your subscription preferences: http://lists.runrev.com/mailman/listinfo/use-revolution
Re: On-Rev and PostgreSQL
I agree with you except there are cases where it IS necessary and doesn't require SSL. I have a customer that has an in house network and WAN (it covers about 60 locations around the US but all connections are by VPN back to the corporate office). I don't have the luxury of having an irev server on their web server for my revlet to talk to (in their case it's an MS SQL database accessed using ODBC). I need to have the revlet communicate with the DB directly and as I mentioned in my last email, I haven't figured out how to include the necessary .dll to do that from a revlet. len Pierre Sahores wrote: It's not realy safe to set up a postgreSQL nor MySQL on-rev backend as a remote bindable rdbms as long as direct communication with those db from the outside world without using an SSL, SHTTP or SSL tunnel will be unsecure. If we need to bind those backends without opening security holes in our processes (login/password transfert over the web, even as MD5 hashes can be dangerous), the best to do is to have the revlet sending its requests to an irev script witch will query the rdbms in localhost mode and send back the result to the revlet. As long as i did'nt set any revlet-irev communication process for yet, i can't realy be realy helpfull about this part of the recommandation but if anyone need some irev-MySQL way to go, i can send some samples. ___ use-revolution mailing list use-revolution@lists.runrev.com Please visit this url to subscribe, unsubscribe and manage your subscription preferences: http://lists.runrev.com/mailman/listinfo/use-revolution
Re: revEnterprise dp-5 / revMedia beta / revWeb beta
I can confirm that cascading menus in a revLet DON'T work right. Comboboxes are a little flaky too but that is intermittent. I use cascading menus pretty much the way Richard discribed them. I have a Reports button and under that I have different groups of reports which each have their own their own line on this menu. I can't take the mouse off of the original Reports button (top level of menus) without it going away. On the same menu bar, selecting menus that only have a single level work fine. It's the cascade that causes the problem and since the very first line of my Reports menu is a cascading menu, I can't select anything below it either. len morgan Richard Miller wrote: David, There is an extra tab in my example, but it doesn't effect anything.

Custom Widget Technique Question
I'm working on a new project and I'd like some advice on how to create custom controls to use on a graphical process display. This will display a water pipeline system with all it's tanks, pipe, valves, flow/pressure meters etc. One of the items I have to display is a water tank and I need to display how much water is in it as both a number and a graphical representation of the water level. I've got the gist of the drawing managed but I'm going to have to have several of these and I don't want to hand create them every time so I'm looking to make a water tank custom control. I need to put it somewhere, send it a current level which would update the numeric display and set the water level. I'd also like to size them so I could have big ones and small ones. That's a long introduction to my actual question. I know I can make a group of the various parts and script the updating and possibly sizing using behavior scripts but once I've created it, where to I put it? Do I create a stack with this group on it and then clone it where I need it? Do I copy and paste (via script)? I can't add it to the Rev graphic object pallet like the datagrid is now. This is not the only custom control I'm going to need so I'm looking for a generic way to handle this kind of thing. In the end, the program will not only have a display of our pipeline but I'd also like to have a separate design program to create the system diagrams in case any other pipelines want to use the program. len morgan ___ use-revolution mailing list use-revolution@lists.runrev.com Please visit this url to subscribe, unsubscribe and manage your subscription preferences: http://lists.runrev.com/mailman/listinfo/use-revolution

To write such all inclusive documentation for every command would be a daunting task and so verbose that it goes too far the other direction (i.e., so much to read that no one would read any of it). It's a fine line that the documentation writers have to walk. In the future, be sure to look at all the See Also entries in the dictionary and read the WHOLE command description. The See Alsos can often point you in the right direction but also, at least in my case, lead me to learn things I hadn't even thought about before so I end up learning a lot more than if I'd had Scott's example laid out in front of me, took it verbatim, and left. You are suffering from the same problem I know I had and I'm sure a lot of others had: The lack of a good tutorial book on Revolution to get you over the hump when you're new to the language. It's my impression that a large percentage of the current Rev users came from a HyperCard (or one of it's derivatives) background and so they've already been over that hump. The simple terse Rev dictionary format is just fine for them. I remember when I started (from a C/Tcl/Assembly background of MANY years) I couldn't even figure out where to start. The whole concept of passing messages and calling handlers it totally different that the in-line code you'd write in C or Tcl. Once I made that mental leap, things just started falling into place. I still had questions that the documentation didn't answer by that's where this mailing list came in. There was always somebody that could quickly fill in the whole in my knowledge. I believe you can still get Dan Shaefer's (spelling?) book Software at the Speed of Thought which was written around Rev 2.1 I think but it was very helpful in getting me over a lot of the rough spots that the dictionary and user's manual didn't cover (and shouldn't have). There are also a couple of HyperCard/Talk books by Danny Goodman that several people here have recommended. I bought them but haven't really read them so I can't vouch for how helpful they'd be to you. You do have a chance to help out humanity though (well, at least the part of humanity that is struggling to learn Revolution): the user comments at the bottom of the dictionary. They are there for just the same kind of problem you were having, in other words, not quite enough meat around the bone to make it clear. If you feel that something might need more (or better) explaination, add a user comment to enlighten the rest of us. If we all contribute a little here and little there, we should end up with a first class reference that everyone will benefit from. len ___ use-revolution mailing list use-revolution@lists.runrev.com Please visit this url to subscribe, unsubscribe and manage your subscription preferences: http://lists.runrev.com/mailman/listinfo/use-revolution

They are different audiences with different needs and have to be spoken to in different ways. What would be cool would be some sort of online documentation resource that had an I Get It scrollbar that would show or hide more or less detail depending on whether it's on the Beginner or Expert end. While were at it, we could have platform buttons so if you only really cared about Windows, you wouldn't see OS X and Linux examples (where they are different).

Adrian, Yes, you can define the function anywhere you like as long as it's in the message path when you want to execute it. But you don't DEFINE the function in the openStack. That is a function (handler actually) all it's own but you can define it in the same script. Remember that it's going to be CALLED when you need it. Since the file name of this stack isn't going to change, the FUNCTION should be able to execute it at any time. len Adrian Williams wrote: Len, Thanks for this. Looks like just what I need!

Re: Launch another app from my standalone
Adrian, SOAPBOX state='mount' Before we go any further, if you're going to get MEANINGFUL help from this forum, you've got to be much more specific when you ask a question or show a code segment. For example: -- function getPathToFile pFile put the filename of this stack into theFile --removed unwanted 'the' from your original set the itemdelimiter to slash put pFile into the last item of theFile return theFile getPathToFile --end function is NOT a function definition! You've written it as if it was going to be executed as inline code. The fact that it might actually do it doesn't matter (in fact, this should throw an error because the getPathToFile is never DEFINED as a function. Why would you not write the above the way I did, i.e., FUNCTION getPathToFile pFile end FUNCTION ??? It uses fewer characters and is the syntacticly correct way to write rev code. The way you have written it, it appears you call getPathToFile with an argument of pFile, then execute 4 statements, then call getPathToFile AGAIN with no arguments. The '--function' and '--end function' are shown as comments. It's only because I wrote the original code (well, actually copied the code from something Trevor wrote) that I know you're trying to define a function. Many other people that might have far better answers than mine (Trevor's) might just skip your message because it makes no sense. /SOAPBOX Since there is a space in the filename, it interprets what you pass as TWO arguments when you've defined (hopefully) only a single argument. If you are going to hardcode the filename as you've shown below... --Use the function put getPathFile(My App.exe) into tFile launch tFile ... then you have to put the filename in quotes so that it will be interpreted as a single argument. You call to the function should be: put getPathToFile(My App.exe) into tFile or I believe if you wanted a more generic solution: put My Multiword App Name.exe into tFilename put getPathToFile(tFilename) would work. Sorry if it seemed like I was going off on you (I'm having a little difficulty with my 13 year old daughter doing what she is told and you're getting the heat for it :-( ) but I think you will find a lot more help here if you tell/show EXACTLY what you are doing that isn't working instead of trying to simplify things for us. It only makes the problem worse. You don't need to include ALL of your code, only the parts that aren't working or are relevant to that code. len ___ use-revolution mailing list use-revolution@lists.runrev.com Please visit this url to subscribe, unsubscribe and manage your subscription preferences: http://lists.runrev.com/mailman/listinfo/use-revolution

Basically, it was just a middle ground between changing the name of breakpoints and going back to red dots =). Brian, Have you ever noticed the dots in Rev's debugger? How, if your script has very many lines at all, the dots can't keep pace with scrolling, returns, etc.? I have. Not pretty, to say the least. So, no images floating around for me, thank you. Also, keeping a separate array of breakpoints and keeping them in sync with the actual code is not easy in a world where tRev is not the only script editor. I used to have lots of these sorts of proprietary approaches. It always came back to bite me in the behind when people traded code with others or used more than one editor. So, a couple years ago, i decided to use text to indicate a breakpoint. Easy to see, easy to delete, follows the code wherever it goes, never gets out of sync. It's all good. Now that we've added record id's as comments following the word breakpoint, we can attach loads of data to a breakpoint. I'm warming up to the idea, too!

A Slightly More Complex revLet Question
I'm trying to convert one of Tcl/TK programs to work on a web server instead of the desktop. Because of the Sarbanes/Oxley Act, this will save them a lot of money. My question is: I can convert the screens/tabs/menus fairly easily to a revLet. In fact, this is going rather smoothly. The problem is that the data to fill the fields comes from a SQL server. I assume that I'm going to need some sort of .cgi/.irev program to send a query to and get the results back from. Will this require a connect/disconnect every time I need to get data? Can I create a generic cgi/irev program to receive a query and return tab delimited records? Better still, can I connect from my revLet and keep the connection open and talk to the server directly from the revLet? As I said in my subject, this is a much more complex use of the revLet than I've seen talked about here. Any help and/or advice would be appreciated.

Re: A Slightly More Complex revLet Question
The particular customer would have the web server farm and SQL Server (Microsoft's) in the same server room so security shouldn't be an issue unless the revlet can somehow be broken into on the client end. Most of the end users have trouble spelling G.E.D. so this is a minimal risk but it is there. Perhaps I AM making it more complicated (in my head) than it really is. I'll have to use ODBC because we don't have either other DB Driver that can speak to a SQL Server. My immediate issue is they would like to see some sort of demonstration of what's possible (after all, the app I'm trying to replace was written over a 10 year period!) not the finished product. Therefore, I'd like to upload the sample program to my on-Rev account and have them access the data on my desktop computer at home (which has a SQL Server and some old data on it). I don't offhand know what port SQL Server uses but I have no problems with them accessing the data directly for a limited time and I don't think they will have a problem with this revLet accessing THEIR SQL Server if they decide to green-light the project. I'll do some playing around with it. Len Morgan KTTK, Inc. Mark Schonewille wrote: Hi Len, Yes, if the server allows it, you can do all you describe. It is indeed recommendable to use a cgi or irev to connect to MySql. I use PHP for this. Many hosts, including yours sincerely, don't allow a direct a connection to a database from a MySQL client. Why would you put effort into keeping a connection alive? I don't think that keeping a connection alive will increase transaction speed significantly, unless you can connect to a database directly, without cgi/irev/php. You can write a cgi or php script, for instance, which interprets a query from your client and executes it. I would consider this rather insecure, because a hacker who finds out how to send queries gets full control over your database. You can get a url or use the post command to connect to a server and send your query from your revlet the same way you can from a desktop standalone.
