Two keys characters combinations (Was Limiting the number of characters per line in a scrolling field)
Hi Dar and Glen, It seems that special characters you can type with a single key (é with a French keyboard, ü with a German one, etc.) which were bypassed with Rev 2.2.x work now correctly since Rev 2.5. But for all characters which need a two keys combination (ü with a French keyboard, é with an English one, etc.), the message handlers (keyUp/Down and rawKeyUp/Down) are still bypassed :-( I did not check Bugzilla...

another multi-user solution?
This morning, while in the shower of course (Mr. Kaufman, the U.N. has decided to elect you Secretary General, on the condition that all of your decisions regarding this institution are made whilst you are in the shower.) I thought of another possible Rev-only solution to the problem of allowing multiple user access to data. Originally I had thought of two or more anchor apps that would subsequently open one of many data-record stacks. But instead of record-stacks, why not record-text-files? While opening a single text file containing all of the records would effectively shut out any other users from accessing the data, if that data was divided into separate text files, one for each record, any number of users could work on them (provided they were working on different records, of course). Plus, there would be the added advantage of easy manual correction should one of the records become corrupted somehow. My needs here are very basic; the records do not have to interact in any way; I don't have to do operations on any of the records in the aggregate (else I could see how opening many records successively would be cumbersome). Before I embark on this option, does anyone see any serious problems with this method?

Hi Kurt,

myself that they need be
A project I was working on started down the SQL road and hit a BIG bump
with the first book on actually setting up and administering an SQL network
on Mac OS X. Do you like Unix command line syntax, aka Apple's Terminal
application? Would you like to walk users through it over the phone as
part of your support effort? Do you want to predefine every data field to
the database...and assign each a data type which may be meaningless to
Transcript? Do you want to ship /or install different versions of server
on different platforms? Then yes, you may be making life more difficult.
Kurt, I was going to suggest you look at working within Transcript's record
locking procedure; but I recall doing that in the aftermath of learning the
realities of SQL. I concluded that, since Transcript reserves write
capability for the first person to open a stack until she closes it, any
scheme that requires concurrent update by more than one user meant opening
and closing the data stack with each read or write--which I considered
unacceptable overhead. But note that all read-only stacks can be shared by
multiple users now.
What you propose with text file databases should work seamlessly within
Transcript and require no third-party software.

One potential problem - if you are relying on the filesystem's locking facilities to control access to files in a multi-user situation, then I'm guessing that the volume that holds these files must be made available to each of the client computers that is running your application. But remember in that case that file locking is not a reliable mechanism on a network mounted volume. If you don't want to use a database, one simple (and somewhat cool) solution would be to have a server stack or resource management stack running on your designated server machine. This application would listen on a designated port. When any of your client applications needed to access a shared resource they would open a socket connection with the server app, get or update the resource in question, and then close the socket. So long as you don't have a whole lot of clients and you don't keep the sockets open a long time this would work just fine. --gordy ___ use-revolution mailing list use-revolution@lists.runrev.com http://lists.runrev.com/mailman/listinfo/use-revolution

To MySQL or Not SQL
I've been up and down with this 'to SQL or not SQL' thing for a while, fearing long monotonous nights debugging arcane commands and crashing, etc. which has been my experience with client server databases used with x-talks in years past. Remember Butler? Holy smoke, what a crashfest. Not helped by system 7's ODBC implementation. I've painfully worked with GoLive 6's amazing but buggy Dynamic feature, which allows you to create webpages that suck data from MySQL and others. It writes php or asp snippets to the web page as well as install a few subroutines on your site. Brilliantly executed, to a point, except it looked like they just ran out of money and stopped beta testing and debugging. Out it went, and with only one bug fix version (the first version wouldn't work at all) that was it, in typical Adobe fashion. There are no more bugs in this product. So I had to tough it out with the unfamiliar PHP code calling SQL from html. Pretty crazy. But one thing in all my struggles was constant: my MySQL server hosted at Dreamhost. I gotta tell ya, if you guys don't have an ISP that includes mySQL, python,perl,mysql, quicktime streaming on a Linux server... move!! This stuff works, and one of the benefits of my particular webhost is that MySQL is part of the deal. They maintain it, and you secure it, put data in, and use it. For $10/month! Why bother running one's own server for most projects if installation is painful? But, getting to the point, I recently started a project that included a client-server function and I felt that this might take a while to get running. I actually tried to make a 'mock-database' in globals thinking it might allow me to get on to the other parts of building and come back to it; you know, hook it up later. Well I was debugging pretty much what would start to look like SQL calls anyway, so I just scrapped it and was determined to do it the 'right' way. I got Sarah's fine SQL stack, which demonstrates some of the built-in SQL functionality of Rev, with a very nice layout and a simple dislplay of data that I hadn't seen before -- thanks for the idea..and it inspired me to just dive in. Still I needed a bit more functionality and ease...too many things to open and close, cleanup etc.. THEN.. after a tiny bit of searching I found Trevor Devore's libDB... finally, a simple, logical way to deal with database calls. And it works, fast and clean. And all based on Rev arrays. Yesterday, I reached a milestone in my project, I got a moderately complicated multi-call SQL report working...and it took about 2 weeks after I decided to go for the 'real deal'. So I'd say, if your project can use client-server functionality now or in the future, do it! Use Chipps altMYSQL lite if it's imbedded. It just works and saves time for other things, like the interface! SQL itself is pretty easy as a language. It's verbose, self describing and consists of 40 or so commands that all make sense. Sometimes it's almost like Transcript! You usually only need to know a few commands to get a listing or a single record. It's a little more involved to insert and create records, but not much with Trevor's lib. And if the data doesn't need to be entered much, one can always manage the data input side with a SQL client such as CocoaMySQL and many others. I save various SQL calls in custom properties to avoid a lot of the quoting problems, and Trevor's lib also cleans up the entered SQL calls. Speaking of verbose, I'll stop.

Table Formatting
This may seem like a simple question but how do I format a table field with different widths for the columns and a header? What I want is a three column table with a single digit in the first column, a dollar amount in the second, and a (fairly) long description in the third. I also want to have a set of titles above the table denoting what each column is for. I looked up table in the documents and don't see much that would help me. Thanks in advance...
