Re: Identifying a certain Windows machine

[Peter Alcibiades]

Don't bother.  

All they have to do is install in a VM, or even in Wine.  Then if they move
the VM, or the Wine folder, the machine ID stays the same.  So you don't
achieve anything, all you do is annoy your less sophisticated customers, who
will find someone who knows how to defeat it.  But it gets worse.

The problem is, they will feel they have a legitimate need to be able to
move their install from one physical machine to another.  They will feel
that a restriction to one particular machine, as opposed to one
installation, is not fair.  However, what you have then encouraged them to
do, installing on a VM, gives them the ability to install as many copies as
they want, wherever they want.  Its counterproductive.

Then, you'll start to think, maybe there is a way I can detect and ban VMs. 
And Wine.  Yes, maybe.  How will they see that?  Will inability to run under
Wine or in a VM seem to the customer like a value added feature?

Just don't let the user save the file if you only want it run just  
after the download.

use:

No apologies necessary Sarah- It's quite reassuring to know you also  
go through these episodes of agony.


I just went thru a similar thing trying to figure out why datagrids  
weren't working in a stack that I now want to make into a separate  
unit of a standalone.


I'm curious how you go about protecting the external stack files in  
your project.

I was just coming to post a question about that when I read yours.

If you use Gmane to search the mail list archives for "socket" you will 
find other examples. Also, there is a chat server example called

I fixed this problem by getting rid of the protected stack (which is
what I wanted to do anyway).
But the question remains: if I choose to specify inclusions, how do I
include the data grid library?

Standalone issues

[Sarah Reichelt]

I have an app that uses a separate protected stack file.
I do not want this stack file bundled into the standalone.
In use, I install this stack and then set the mainStack's stackFiles
to include this separate stack file.

In Standalone settings, I cannot get them to ignore this separate stack file.
The "Remove Stack File" button does nothing.
Setting the stackFiles of the mainStack to empty before creating any
standalone settings doesn't help.

My debugging shows that it is getting this stack from the list of
stackFiles, but when I query the stackFiles, it returns empty.

So how can I either stop this stack file from getting into the stacks
list, or remove it when it gets there?

I have looked at the standalone setting custom property set, but I
can't find a property that includes the list of stacks.

I will keep wrestling with the problem, but I hoped someone might have an idea.

Cheers,
Sarah

Data grids in standalones

[Sarah Reichelt]

I have an app that uses data grids, but as one of the stacks is
password protected, I am selecting the inclusions for the standalone
manually.
I think this is stopping the data grid library from being imported
automatically into the standalone, so when I try to display any data
in a data grid, I get an error like this:

Executing at 10:33:21 AM on Tuesday, March 30, 2010
Type: Chunk: error in object expression
Object: group 'DG1' of card '...' of stack '/Users/sarah/.'
Line Num: 3629
Hint: _table.CreateControlsForColumns

Can I tell the standalone builder to include the data grid library
even if setting inclusions manually?
Or do I have to un-protect my stack to get this to work.

BTW, the protected stack is a separate file that doesn't need to be in
the build since it is stored else where and installed as required.
But I can't make the standalone builder remove it from the list, so it
seems like it has to be there.
But that's a separate problem.

Cheers,
Sarah

DataGrid Forms, checkboxes and Pull-Down buttons?

[John Patten]

Hi All...

I'm using datagrids to display some data out of a mySQL database. I  
created a check box and a option button in the template for my data  
grid row.


I would like to be able to check if data row checkbox hilite is true  
or not and would like to store data in my db based on the option of my  
option button.


How do I get the hilite of my individual checkboxes in each row, and  
along the same lines, how would I get the information selected in my  
option button from each row of the datagrid?



Thanks in Advance!

Effectively, Crystal Report appears as a native object in Microsoft
Visual Studio.
For now I have never used it but as far as I know the Crystal Report
product comes with an independent application to create and exploit reports.
Crystal Report is, among things, capable to make reports on SQL and MySQL
database.

The idea could be to launch the Crystal Report application with RunRev.
But I don't know the possibilities and limitations.

I have read somewhere that it is possible to display a report in a
browser but I suppose that is an ASP.net ability.

In this section you will reach the first Step by step stack devoted to palettes.
The subject of this first part is : palettes with an orientable titlebar.

This stack explains :
- How to create the palette.
- How to move the palette.
- How to skin the titlebar.
- How to change the titlebar orientation.
- And in Mac OS X, how to keep the shadow border effect of the palette.

Re: Printing in Linux

[Richmond Mathewson]

 Now I'm less sophisticated than Peter Alcibiades and Richard Gaskin
when it comes to computery stuff; but what I do know is that every other
program I have ever downloaded onto my Ubuntu box that "does" text
or images allows me to print to my printer (whether it be connected directly
to the Ubuntu box, shared on another computer via a router, switch or hub,
or via a printer server - tried them all today, just to be bloody-minded).

I also know that I can print directly from RunRev 4 on Mac OS X and Win XP.

So I am not terribly excited about some putative upgrade in "4.5" to allow
one to print to PDF so one can then fudge a print-out from that (especially
if it is going to be an Enterprise-only 'thang'; I can see buckets and 
buckets

of RunRev programmers forking out the difference between Studio and
Enterprise for some printing fudge that isn't capable of doing what
everything else can do everywhere else).

From an extremely selfish angle: if I produce a piece of software that
has  a "dirty, fat PRINT button" on it, I want it to do what it says -
PRINT - regardless of whether it is deployed on Mac, Win or Linux.

But, Hey, I want RunRev to pick up on all the fonts installed on a
system as well; I'm a greedy bu**er . . .  :)

Re: Printing in Linux

[Peter Alcibiades]

"If the engine is the same and the variance lies with the drivers, it
would seem you've found your answer."

Yes.  But what I don't understand is, why is Rev the only app that has these
problems?  Open Office prints identically to my home printer, to cups-pdf,
to the office printer, on Mandriva or Debian or Ubuntu.  So do text editors.  
Rev must be doing something very different.

There are problems with Linux printing drivers, but they have to do with
making printers work, not all do.  They are not these kinds of problems.

I gather that in 4.5 there is going to be a print to pdf in Rev itself. 
That has the potential to solve the problem at once.  If you can print to
pdf, you can then pass it to some pdf reader and just print from that.  But,
but, if I understood correctly, this facility is only going to feature in
the Enterprise version?  That is just not possible, is it?

Re: Rev standalone app stays in memory on my Xubuntu 9.10

[hmspotato]

Hello Len,

Thank you for responding to my question.

I hope I am a little better than an average computer user, but I have a
very long way to go before qualifying to be a geek. Could you explain
what it means to have an open socket in the program?

I am a mere teacher, and my program is a simple app to keep students
record according to their class. All data is saved locally inside data
stacks. There is no network connection or connection to external
database. Before quitting, all open stacks are closed.

My program works (i.e. quits cleanly) on other computers running Xubuntu
9.10, Mac OS X or Windows. The anomaly occurs only on my laptop running
Xubuntu 9.10. I would think that my coding in Revolution must be ok, but
something is not right on my laptop, on which my app fails to quit
cleanly. However, oddly, on the same laptop, another app I made quits
cleanly.

Can you suggest what I should change on my laptop?

Daft idea for commercial software ???

[Richmond Mathewson]

 I have been thinking about all the cafuffle about registration numbers 
and so
forth; and wonder, given the fact that some level of pirating will go on 
if a piece

of software is worth anything, if it is really worth all the mucking around.

So:

I should like to float this idea and welcome all reactions and criticisms:

I release a crippled demo which contains a page that lists my Paypal place
and informs would-be buyers that within 48 hours of my receiving via
Paypal I will either e-mail them as an attachment or direct them to an 
ftp folder

where a full version of the program is with a banner of some sort plastered
across the front page / opening screen saying something like:

"This version of Z is the property of  and as such may only be 
used by

him/her/it."

No doubt some folks will share their personalised versions with their 
friends,

relations and so on; but that will probably happen anyway unless I go down
the painful route of tying programs to mac addresses.

Re: Updating running apps

Sarah Reichelt wrote:


I have some apps that when checking for updates, then offer a "Install
& Relaunch" option.
This seems really cool to me, but I haven't worked out how to do it in
my Rev apps.
If I am only updating separate sub-stacks, then I can work it out, but
if I want to update the actual application file what can I do?

I can get the existing app to download the new version, but then what?
Can a running app replace itself on disk?
Then how to tell it to quit & re-launch?

On a Mac, I guess I could spit out an AppleScript to quit the app,
re-locate the downloaded app, then restart it but the apps I have
don't seem to start an AppleScript when doing this.

Any suggestions?


I started down that road a while back, and then I realized that what 
made it seem cool and exotic is that almost no one else does it.


Most apps download, some also install, almost none can use the new build 
without quitting the old one first.


With Rev, using an anchor window pattern (sometimes called the "splash 
stack" for those who don't also update their splash screen) you can 
download compressed copies of your stack files, decompress them and 
overwrite the old ones, issue a revert command, and you have a new version.


Sounds good, but in my brief experiments down that road I quickly 
realized the wide range of things that can go wrong attempting to update 
components on-the-fly:  to do it well you need to write a fair amount of 
code to restore globals (and hope you're using the same ones), save and 
restore window states and data states, etc. ad tedium. Too easy to get 
your fingers caught in the fan blades if you forget something.


Requiring a quit-and-relaunch lets you have a clean initialization, 
without replicating a more complex version of that initialization in vivo.


And you'll have no complaints about having to quit and relaunch from 
your end-users, since they've probably never seen an app that does it 
any other way.


Whether you attempt to update in vivo or go for the more common 
quit-and-relaunch, managing components can be made simpler by using a 
version file hosted somewhere with your app, with its URL stored in a 
custom property.


If you do this sort of thing often, you may consider using the Rev 
Interop specs for that - see the ECMI document Ken posted in the Files 
section at:



I don't know if Trevor uses the RIP properties outlined there in his 
updater, but I see that he uses them elsewhere in things like the Data 
Grid, and with the RIPEdit tool also available in that group I've been 
adding them to all of my libraries as well for a variety of version 
control and managements tasks.

Re: Richard & the Mac Classic build ???

[Jeff Reynolds]

Richmond,

I totally agree and they can continue to be supported via the classic  
products like rev 2.6.1. its just that if you force the modern cutting  
edge stuff to be all backwards compatible with the stuff over a decade  
old, the cutting edge will be pretty dull and pretty expensive and  
probably pretty buggy.


In the ed market i have had to produce cdrom for kids (at least up  
unitll the last one in 2009) in osx and classic, there was a big  
enough market there using the old equipment that you had to have it  
supported. luckily the feature needs were still w/in the bounds of  
2.6.1 so i could continue those projects in the old version with no  
problems and build classic apps in 261 and then the osx and windoz in  
a more recent version of rev. bit of a pain, but worked fine.


a lot also boils down to who will pay for the development of the stuff  
for the old machines in both the authoring/programming system and the  
content/apps. the old guys dont want to pay for all the bleeding edge  
development stuff and the new guys dont want to pay for the legacy  
machine development. if you split the markets into tow then you have  
the problem of two development streams (no longer really a universal  
product) and two smaller markets which means a higher price for each  
individually most likely.


not saying chuck all those old machines, but you cant have your cake  
and eat it too. either we dont have a lot of innovation and new  
features so we can continue to support all the legacy machines still  
running out there, or we have a lots of advancement and we have to cut  
off producing new stuff for the older market which then shrinks rapidly.


unfortunately i dont think there is a perfect solution here (unless  
you have a magic wand and some bunged up latin to go with it)...

Front Scripts vs Behaviors

[Peter Haworth]

I have several event handlers for common events such as mouseUp,  
openCard, menuPick, closeField which are installed as front scripts.  
The reason for this is to grab these events as soon as possible in  
order to handle any updating of the SQLite database I use to store the  
data for my app.  The handlers do various checks to make sure they  
need to handle the message, take action if necessary, and pass the  
message on so the handlers for these events in the controls themselves  
can take any further action needed.


This all works quite nicely although I've experienced some grief and  
hard freezes because of things like mouseUp coming from unexpected  
places like the IDE stack objects or the script editing window in  
debug mode.   I suspect I'm taking some performance hits as well since  
every single one of these events has to go through my front script  
handler.


I'm wondering if it might be better to do this by having behavior  
scripts for each type of control.  That would eliminate the need for  
checking that I'm dealing with a control I care about, the issues with  
events coming from unexpected places, and any performance issues.  On  
the downside, I'd need to come up with a way to allow each control to  
carry out any local processing it needs to take care of (dispatch?).   
It would also involve a small amount of extra work to specify the  
behavior every time I add a control unless I developed my own tool  
palette that had the controls already set up with the correct behavior  
so I could drag and drop them where I wanted them.


I'd appreciate some guidance on this, either philosophical or practical.

Thanks,

Pete Haworth

Now; were the Runrev folk to say "Yes, we are listening and we are aware

And, were they to say "No." We would know where we stand as well.

OK _ I just checked out the latest glxApp

it seems that you need to use the Rev IDE to create the standalones:

And that you can't use the glx application packager outside of the  
IDE:
The application packager would ideally run as a standalone  
application but
during the packaging process some scripts are modified which exceed  
the 10
line limit. So for the time being you must package from within the  
IDE.


But it may still be possible to automate from within the IDE? Has  
anyone
hacked into the rev / and/or glxApp stacks to automate builds in  
cases where
you need to do this daily? NB - the splash stack approach will work  
in some
cases, but may not work for revWeb applications, and won't work for

apps!


On the Google Group I handed out a url to an unreleased version of the  
framework a few weeks ago. The plugin included with that distribution  
has a will that will automatically build standalones for you. Just  
look on the General tab. Here is the thread with the download link at  
the end:


http://groups.google.com/group/glxapp/browse_thread/thread/c0c7cc1607be2e4b

I added this in when I kept getting customers who complained that the  
version info in my executables didn't match the about screen during  
the BETA testing phase. If you just update your stacks when you  
automatically install an update then your version numbers will always  
be out of sync. For this reason I always update both stacks and  
executables now.


You will notice that the build button is included with the IDE plugin  
rather than the application packager. This is because I have to code  
sign the Windows executable before I can send it out to users and I  
haven't sat down to figure out if I can automate when running on OS X  
and using VMWare.

Re: Rev standalone app stays in memory on my Xubuntu 9.10

It sounds to me like you've got an open socket or file laying around in 
the program that is preventing it from closing.  Check your sockets and 
open files when you quit (handle the quit stack message).  Maybe a 
driver on one machine is not releasing the socket and so your program 
stays around waiting.

I'd like to set up an automatic build for a project, so that rather than

The process by which standalones and revlets are made is handled in the 
development engine (v4.0 and later), so RunRev has more security over 
that feature and conceivably they could publish the API so we could make 
any sort of standalone builder we want.


But that's a lot of work (the engine only handles a portion of all the 
steps that need to be done), and in your case you may find it simpler to 
just use the messages the Rev standalone builder sends to your stack 
before and after the build process.


A savingStandalone message is sent just before the standalone/revlet is 
generated, and a standaloneSaved message is sent after.


You could use the standaloneSaved message to scoop up the resulting 
revlet stack file and FTP it to your server.


For standalones you can either use the revZip library or on OS X just 
shell to disk_util to make a zip file of the standalone, and then upload 
that.

Yes, at least that is what I would try. Sub-stacks cannot open in a
separate window, but I believe that they can open in the same window.
So you could have your splash screen stack (& main app) open, then it
could use: go to stack "Next" in this window
where "Next" is the stack that changes frequently.

Your updater just needs to upload a new version of the "Next" stack as required.

I haven't tested any of this, but I think it should work.

revWeb: strategies for loading large stacks

[David Bovill]

Given that it is really important to have a web app load FAST - what
strategies can we use to incrementally download an app - providing
interactivity immediately to the user whith content downloading in the
background?

   1. Images, and other media loaded with a "load url" call as / when /
   before needed where they will be cached in the revlets memory as a script
   variable in LibUrl?
   2. Text files loaded and used to generate new content using the revLet

How about:

   - loading substacks into hidden divs - so they are ready to use later,
   but the html page loads first showing the main web content and splash
   revlet.
   - loading substacks in some way from the revlet and somehow refreshing
   the substack in the browser page?
   - using an AJAX call to load another revlet in a page (but this would
   also require downloading the revlet engine added to the stack again as a
   second instance)

Any ideas how to best download incrementally large projects as you would
with game levels or other large apps?

Re: Automatic Builds

[David Bovill]

OK _ I just checked out the latest glxApp
tutorials
it seems that you need to use the Rev IDE to create the standalones:

*Note: *Currently you need to build the executables for both OS X and
Windows before using the application packager.

And that you can't use the glx application packager outside of the IDE:
The application packager would ideally run as a standalone application but
during the packaging process some scripts are modified which exceed the 10
line limit. So for the time being you must package from within the IDE.

But it may still be possible to automate from within the IDE? Has anyone
hacked into the rev / and/or glxApp stacks to automate builds in cases where
you need to do this daily? NB - the splash stack approach will work in some
cases, but may not work for revWeb applications, and won't work for mobile
apps!

Re: Automatic Builds

[David Bovill]

Hi Sarah - I've not done much more than experiment with revWeb yet, but now
with the "do as JavaScript" feature, and a client that can use that, I'm
looking to set up an agile deployment prototyping the eventual AJAX front
end in revWeb. As the app will be deployed to the test site every 2 weeks to
be tested by the client and every day by the development team, I'm looking
to automate that.

I understand the approach you describe for desktop apps - but you are saying
you can use it for revWeb stacks as well - or not? That is a plain rev stack
can be loaded dynamically with a "go to stack url ..." call and opened as a
substack - just like with a desktop app? That would be great.. but.. how?

 So you would:

   1. build the main app as a splash / glxApp application and then
   2. store the body of the app as plain stacks on the server to be loaded
   by the revWeb app as needed?

Each substack is usually in it's own div - right? So this would be the case
here as well, and in a way you are loading stacks from the internet as you
would AJAX calls? Sound like a great hack - or am I making something weird
up here?

Check out Trevor's application framework, that supports builds and much
more.

Sounds like a job for a splash screen app that opens a separate sub-stack.
If you build the splash screen once, then in future, you just need to
save & upload the sub stack(s) to update the app.
The HTML wouldn't even need to be changed unless you wanted it to show
a version number or something like that.

Cheers,
Sarah

Automatic Builds

[David Bovill]

I'd like to set up an automatic build for a project, so that rather than
manually exporting the stack as a standalone, I would create an interface
that allowed the stack to be compiled as a revWeb stack (possibly other
standalones). and then ftp'd up to the web server together with the
appropriate html. What's the best way to acheive this?

Thanks in advance,

David

Re: Printing in Linux

[Peter Alcibiades]

Here is what happened.

I changed the distribution that an application is running on from Mandriva
to Debian.  Because revPrintField doesn't work properly, it resorted to
getting prints out by using print card.  After the change in distribution,
print card worked, but it did not print the card in the same way as before,
it didn't print into the correct area.  This is probably something to do
with the screen resolution.

So, wishing to resolve this at leisure, I took it home and tinkered,
intending to use cups-pdf as the printer. The first thing to do was set
cups-pdf as the default printer. Then to work.  

The print card command, and this is with a card with a few simple text
fields, was timed at 1 minute 20 seconds to print to the file.  The file
appeared to go into a black hole.  cups-pdf is set up to print into a folder
called PDF in the home directory.  Nothing appeared there.  Tried other
applications.  They all now printed to /home/user/PDF without fuss.

Checking the available printers in Rev revealed the ones that are installed,
including cups-pdf, and one that is not, namely PDF.  Change the printerName
to PDF, and the print files do now arrive in the /home/userPDF directory.  

This is very reminiscent of the font situation:  fonts which are not
installed are listed, and fonts which are installed appear to be
unavailable.  Where does it get this printer from?  And what would happen if
you changed the cups-pdf configuration files to use some other directory? 
Life is too short. It still takes the same amount of time to print.

Now at least we can start tinkering with the print card into command. 
Whereas before print card into 100,100,800,600 had worked, now on one card
what was needed was 0,20,600,400 and on another 0,10,800,600.  I have no
idea why.  

When doing all this stuff, it would help to be able to read the dictionary,
but it is in unchangeable 4 point font.  Never mind, one can use a large
magnifying glass.  Which I do, believe it or not.

This by the way is still using 3.5.  Tried to use 4.0, and it would not
allow any editing of the app.  No idea why.  Lets hope that 4.5 improves
things.
