Redirecting Console Application Stdin/out

I would like to be able to spawn from a Windows application a console application (such as ftp) and redirect the standard input and output.  In particular, I would like to be able to take the standard output/error and send it to a text box on the screen instead of appearing in a DOS window.  Microsoft's developer studio does this when it compiles code.  How do I do this?  I believe it has something to do with CreateProcess and the handles you can specify in the STARTUPINFO structure, but I don't know which handles to specify or how to link them to a text box in my windows application.
