How to hide app in the Win95 task list?

[Karl Spaelti]

Is there a way to make sure an app does not show up in the Win95 task list.

I have looked at Mike Blaszczak's stealth example which does not show up in the WinNT 4.0 task list. It is visible in the Win95 task list, though.


Thanks for any suggestions.

Karl.

hi,
goto resource script file and edit manually the dialog based application,
there set the window class style as WS_EXTOOLAPPWINDOW
bye

The window style is WS_EX_TOOLWINDOW. But that will make the application not to appear only in the task bar but if the user presses Ctrl + Alt + Del, it appears in the task list.

Any solution to make the application invisible in the task list ( a little pop up window that appears when the user presses ctrl + alt + del )

Try looking at the following Win32 function:
RegisterServiceProcess.
It should make the process invisible when looking from the Ctrl+Alt+del window.

BTW, I tried the WS_EX_TOOLWINDOW style but it didn't work for me for some reason. do you know what could it be ???
