Gerry,
As an alternative to RUN /N the ShellExecute() WinAPI call gives you a lot more control. There are some examples on my website under Q&A, General. And the file spyin.zip has an object wrapper that makes the function a little easier to use.
>Another question related to this form is that when I RUN the Eudora.exe, the DOS window always shows up. Is there any way to hide it?
