>How can I launch an exe from my VFP application and continue to run the code only when the launched exe is finished?

As Daniel mentioned Ed Rauh's API_APPRUN can do this and a number of other things. This is also possible using the Run method of the WScript.Shell object. This is covered in the second (October, 2000) of the series of articles that Ed and I wrote for the VFUG newsletter. The articles are available on-line at www.vfug.org
