MFC, Using the CONSOLE for output from a Dialog-based MFC App

Using the CONSOLE for output from a Dialog-based MFC App

Author	Message
David W. Roger #1 / 4	Using the CONSOLE for output from a Dialog-based MFC App I have a GUI app that I would like to have send its log to the Console of the DOS Window that initiated it. Can this be done? Is there any information on this anyplace? Thanks, David Rogers

Tomas Restrep #2 / 4	Using the CONSOLE for output from a Dialog-based MFC App David, Yes, this is perfectly possible. Look at Knowledge Base Article Q105305 "Calling CRT Output Routines from a GUI Application" for details. -- Tomas Restrepo http://members.xoom.com/trestrep/ Quote: > I have a GUI app that I would like to have send its log to the Console of > the DOS Window that initiated it.

David W. Roger #3 / 4	Using the CONSOLE for output from a Dialog-based MFC App Thanks, Tomas. That article shows me how to allocate a new console and output to it (Q139640 is also useful in this regard), however I don't see a way to output to the DOS window that initiated me. Am I missing something there? David ------------------------------------------------------- Quote: >Yes, this is perfectly possible.

AFAIK, cmd.exe (nt) and command.com (9x) don't set the standard handles correctly before spawing a GUI process, so you don't have a way to get them from the gui process. Though I haven't tried that, I believe you might be able to get around that by createing a second executable, which is a console application. All it would have to do is get the stdhandles and spawn the GUI app, inheriting them to the GUI. SO in the GUI, you would have the correct handles, adn you would be able to set them up like Q105305. It's just a thought anyway. -- Tomas Restrepo http://members.xoom.com/trestrep/
