Detecting program close

[pskyboy]

Hey Guys

i was wondering if there is anyway to detect when a user has closed an application. i have launched teh app using shellexecute and want to delete the file it opened when the program is closed.

u could Set a timer and use FindowWindow to find the hwnd of the window u opened by its caption and if the return value is 0 then the window can't be found and its been closed... then u could do delete the file and kill the timer.. if u need some code to handle this tell me and i will code something up right quick for u...

Get the process handle from ShellExecuteEx (use that instead of ShellExecute), then you can use WaitForSingleObject until the shelled object closes.

#include <windows.h>
SHELLEXECUTEINFO sh;
strcpy(sh.filename,"myfile.exe");
// there are other parts of the struct to fill out...
int ret = Shellexecute(sh);
// this pauses the program and waits until the 
// shelled programn exits
While( WaitForSingleObject(sh.hProcess,INFINITE) == 278{
         Sleep 2;
}

Also a message hook can monitor the appropriate messages (WM_DESTROY, WM_QUIT).
