Marcus,

The app startup crashes are usually more related to the lack of the current DCOM installed on the machines. Check the FAQ here I think Ed Rauh posted an article on solving it.

You don't need REGFN() to work with the windows API any longer. You can DECLARE the function and call it directly:

declare integer FindWindow in win32api ;
string lpClassName, ; && pointer to class name
string lpWindowName && pointer to window name

lnHwnd = FindWindow( .null., "Visual FoxPro 6.0" )


>I've been using the following Foxtools function to check for other instances of my app - GetWind=RegFn('FindWindow','CC','I') &®ister function. I have a few customers who get C0000005 or Illegal operation errors as soon as they start my exe. I've also noticed that I occasionally get 'Invalid API call' when running my code in development mode, and I am now wondering if these issues are related. Anyone have any experience with this? It started happening after we went from VFP3 to VFP6. TIA
