re: Background Color on Win XP - Undocumented Feature!

Scroll down to Order 6 (concatenation) (But why isn't concatenate in the Index?!?)

Re: Confirming a Save command
I've tested this procedure out, and have found that on the Macintosh platform, if the stack being saved is locked, the save command produces a copy of the stack with the same name and followed by a tilde. One also gets a message in the result variable which says Can't open stack file. If you save a second time, the message in result is Can't open stack backup file. If it's the wording that bothers you, you can go into the Metacard Menu Bar stacks and change the wording. I did that with the Save dialog stack, to use File instead of Stack. I have not used it in a standalone yet, but it works fine in development mode. Then just make sure to embed/import that stack into your project. Also, my current project has a save file. This file is critical to the program. It reads the file on launch, pulls out a bunch of information such as user preferences, high scores, etc. and puts them into the program, since a standalone cannot remember. The program saves to this file often, behind the scenes. If the file gets mangled, the program will follow. So I have a set of data on card 2 of the save stack, a set of default information. When it launches, it checks the status of the saved data on card 1. Making sure numbers are numbers, if there are supposed to be 5 items, there are. If a value is supposed to be A or B, it is one of them. And if this check fails, the stack will pull the default data from card 2, which doesn't change, put it into card 1, and launch in default mode. The user will have to reset preferences and create new high scores, but at least they won't have to reinstall the program, if the data gets mangled.

[ANN]: VAPP, V4RB, V4MD, V4WS, VSDK, VCSDK, VXCMD 1.9.6 beta16
Hi Everybody, I have made a lots of *Valentina house* clean up work here, In particular I have convert all product projects to CodeWarrior 8 format, polish Macho versions of products, ... Now you can download 1.9.6 b16 for most products. * FIXED crash of V4RB on Jaguar. * FIXED LIKE problem with non-English languages on Windows. * FIXED small problem with encryption and indexes. * introduced VXCMD macho version for MetaCard and Revolution. Please test this latest beta. It must be stable and good even for release. -- Best regards, Ruslan Zasukhin [ I feel the need...the need for speed ] - e-mail: [EMAIL PROTECTED] web: http://www.paradigmasoft.com To subscribe to the Valentina mail list send a letter to [EMAIL PROTECTED] - ___ metacard mailing list [EMAIL PROTECTED] http://lists.runrev.com/mailman/listinfo/metacard
Looking For Suggestions
I've got a standalone that needs to run on Windows as a single instance (no multiple instances of the same app). I'm looking for suggestions on how to prevent duplicate launches of the same app (the app may also be installed in more than one location on the same machine). I'm familiar with the open apps function of the EXT DLL, but I'm trying to avoid use of this since it makes my apps unstable. I've also toyed with the idea of writing an app busy message to the registry or a temp file on the drive, but I can't figure out how to determine if the app that created the message is running As far as I know, MC has no built-in way to get a list of open processes other than those it has already launched. Searching the Web, I came across this document -- might there be some way to use the code here via the shell or shell(start...) function? http://www.mvps.org/access/api/api0007.htm Thanks for any suggestions.

So if you find the temp variable, shut down. Thanks for the suggestion. However, it doesn't take into account a situation where the app is unable to clean up after itself, such as after a system crash. Then the system would be stuck with an app busy message and be unable to launch the app at all. If there was a way to identify the app busy message with, for example, an addressable ID of the running app, your solution could work, but right now I can't see how this is possible. This problem is a little more complicated than it seems. :-) Regards, Scott Rossi Creative Director, Tactile Media ___ metacard mailing list [EMAIL PROTECTED] http://lists.runrev.com/mailman/listinfo/metacard
Re: Looking For Suggestions
There may be something more elegant, but how about a time-stamped file? Could your app just stamp the current time into the file once per minute? A second app could then check if the file is "alive" by checking the time contained within. One other trick that might work: what if the main app opens up a socket or other means of IAC? Then the secondary app could attempt to "ping" it locally. Brian

RE: Looking For Suggestions
Scott, Don't know if this helps but executing mem /p from a dos window will return all running programs. So, you might be able to run a batch file which prints out the running programs and check it from there.. -Chipp -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED]]On Behalf Of Scott Rossi Sent: Tuesday, September 17, 2002 6:36 PM To: [EMAIL PROTECTED] Subject: Looking For Suggestions I've got a standalone that needs to run on Windows as a single instance (no multiple instances of the same app).
