Waiting for a DOS application to terminate?

[Dietmar]

Hello.

I want to write a windows frontend for a DOS tool.

So I call the DOS app and the DOS box pops up.
Then I have to wait until it has finished
before I can proceed. But how do I know?

I tried to use FindWindow() and look periodically
for a window title with my DOS application name.
But that is e.g. different in WinNT as in Win98.

Any solutions?

BR,

Hi,

Use OpenProcess to get a handle to the process.
(Or use CreateProcess to create the process and to obtain the process handle)
Then use WaitForSingleObject to wait for its termination.

Do you mean this?

WaitForSingleObject
(hHandle, // = hProcess from struct PROCESS_INFORMATION
timeout);


In Win98 the DOS box is still visible after termination.
Does this work anyway?

Hi,

yes, it's the hProcess member of the PROCESS_INFORMATION structure.

I don't know what happens when the dos-box keeps visible. Try following:
STARTUPINFO's dwFlags contains STARTF_USESHOWWINDOW
STARTUPINFO's wShowWindow is SW_HIDE
