Hi All,
I have been going round for a few days on an issue here... Basically, I
have a 3rd party app that allows the user to exit even if the app is not in
a safe place to do so. This results in data corruption and a host of other
issues. The developer of this app is not willing to do anything to prevent
this, so I am doing it myself.
I now control where or not the user can use the File/Exit , System Menu, or
Shutdown/Restart to exit the application based on the apps state. When it
is safe to close I re-enable those exit methods. The two methods I have not
been able to stop yet are: Alt-F4 and End Process in task manager.
I was referred to madshi's madCodeHook to handle this, but have not had a
lot of luck getting it to run as expected when injected into an app. madshi
actually recommended that I use SetWindowsHookEx instead of madCH. My
problem there is that I cannot seem to find a way to monitor for WM_CLOSE on
a single process. It seems wasteful to set a global hook when only a couple
of the processes might be affected.
Can anyone think of any alternatives? Maybe I am just missing something
obvious?
I would love to see a demo that would intercept and block the WM_CLOSE for
notepad.exe. If it is possible, then it should be fairly simple.
Anyone want to help me before my head explodes?
THANKS!
Dave
