I wrote a C++ program that runs system calls. One of these system calls executes a Program A that is run via command prompt. When this program runs, the command window opens and closes so fast that I can't read the error that Program A is spitting out. I tried addeding in pauses after the system call but that doesn't help. I tried taking screen shots but I can't catch that split second that the window is open.

Does anyone have any other suggestions? I'm out of ideas...


Thanks!!

Open a DOS prompt and run the C++ program from the command line as opposed to clicking on the executable.

You can also try a system("PAUSE"); depending on what compiler your using.

I can't do a system("Pause") because by the time it's executed, the window is already closed. The executable is run through another program, so although I can run it through a DOS prompt, for reasons that are too long to explain, I need it to work through this other program...

This might work.

Instead of running your_prog.exe, try running:
command /K your_prog.exe
Then manually exit the DOS window when finished.

Had another idea.

This works in Windows 98 (not sure about others):
load up a DOS window
click the 'Properties' button (third from the right)
on the 'Program' tab, uncheck 'Close on exit'

Rufo.
