Visual Basic, A REALLY tough question!

A REALLY tough question!

Henry Ja #1 / 5	A REALLY tough question! I'm building a VB app that runs a Windows app (through the SHELL command). These 2 apps should be the ONLY apps accessible to the user. That means no Program Manager, File Manager, DOS Prompt, etc. Using the API function SetSystemModalWindow() would solve the task-switching problem, however you cannot easily access the 2nd app, once you've locked the 1st app. Basically, I want to be able to access both apps on-screen with the simple click of the mouse without having to close one first. Thanks.

That's easy enough. Just designate one of the applications as the Windows shell (under 3.x, haven't tried it in 95). with shell=yourapp.exe in system.ini. As long as neither program has the ability to run other programs, you'll be fine. You can easily try this with Excel, or another application. you can use the ExitWindows API call to make your app either reboot the system or relaunch Windows on exit.

I haven't tried this, but... Try setting your VB app as the Windows shell (in the boot section of system.ini. there should be a shell= line.) That will start your app when Windows loads, instead of Program Manager, effectively blocking the user from doing anything else. The only thing I don't know is whether you'll be able to start the other app with a SHELL statement.

I'm not 100% clear on EXACTLY what you want to do but it seems to me that the solution is to go into your users system.ini file and in the [boot] section enter shell=(path\)<appname.exe> (instead of shell=progman.exe) where <appname.exe> is the name of your executable. This will mean that Windows will load using your application instead of the Program manager and shutting down your application will close Windows. Hope this helps. Ultan

This makes them invisible to the user (including program manager). They cannot task switch to them, and they do not show in the task list. Peter Carson
