In the program, I started another program with winexec. How can I determine when the program will end?

Execute with shellexcute
Use waitforsingleobject to wait for its end

How to start Program Until it stops running?
Shellexecuteinfo shexecinfo = {0 };
Shexecinfo. cbsize = sizeof (shellexecuteinfo );
Shexecinfo. fmask = see_mask_nocloseprocess;
Shexecinfo. hwnd = NULL;
Shexecinfo. lpverb = NULL;
Shexecinfo. lpfile = "C: \ myprogram.exe ";
Shexecinfo. lpparameters = "";
Shexecinfo. lpdirectory = NULL;
Shexecinfo. nshow = sw_show;
Shexecinfo. hinstapp = NULL;
Shellexecuteex (& shexecinfo );
Waitforsingleobject (shexecinfo. hprocess, infinite );

Or:

Process_information processinfo;
Startupinfo; // This is an [in] Parameter
Zeromemory (& startupinfo, sizeof (startupinfo ));
Startupinfo. cb = sizeof startupinfo; // only compulsory field
If (CreateProcess ("C: \ winnt \ notepad.exe", null,
Null, null, false, 0, null,
Null, & startupinfo, & processinfo ))
{
Waitforsingleobject (processinfo. hprocess, infinite );
Closehandle (processinfo. hthread );
Closehandle (processinfo. hprocess );
}
Else
{
MessageBox ("the process cocould not be started ...");
}
