It may be that I'm a dummy, but I have no idea what a 'Form Application (Program)' is. Can you please clarify?

Also, do you mean "_popen" or "popen"?

"popen" is a standardized function, but as far as I known, "_popen" is not. Tell us anything you know about "_popen".

'Form Application' usually means some sort of GUI with a button or an area to enter information in. Like kspangsege said any extra information would be helpful.

form application it synonym to gui or window application: it has forms, buttons, fields with text and etc. i found why my program doesnt work, here is http://msdn.microsoft.com/en-us/library/96ayss4b%28v=vs.80%29.aspx
