>I am having problems using ShellExecute, IsRunning, and WaitforsingleObject together. I am trying to start Adobe Acrobat Reader using the associated .pdf's .xfdf file. Adobe Acrobat Reader opens up fine and uses the .xfdf file as it should. However, I need to stop processing in my app until Adobe Acrobat Reader is closed so I can then delete the .pdf and .xfdf files. I cannot use createprocess because createprocess only works with executables. The handle returned by isrunning is never found using waitforsingleobject. Any idea how can I convert the value returned by isrunning() to a value required by waitforsingleobject?

Tracy,

The value returned by my work is not the value type that WaitForSingleObject() requires. You'll need CreateProcess(). Ed Rauh's API_APPRUN stuff uses this. You might want to look at that for ideas on how to implement what you want.
