>>Does anyone know how to associated a certain extension with a program, using VFP or VFP API calls. I would like to associate the TIF extension with the wang imager windows 95 and with kodak imager for windows 98. Users can't seem to do this on their own. I have been doing it manually for so long it is second nature, but I cant get a 50 year old engineer to understand the concept even with the best documentation I could create.

On my machine they are of TIFImage.Document. You then would then look up TIFImage.Document in the lower half of HKCR, and navigate to the string contained in HKEY_CLASSES_ROOT\TIFImage.Document\shell\open\command. My machine has "C:\Program Files\Windows NT\Accessories\ImageVue\WangImg.Exe "%1"".

One dangling question, do you think after I make changes to the registry to accomplish this, will the user have to reboot inorder for the changes to be in effect?
