Hi!

It is called 'Callback function' and you cannot do this in VFP directly. You can make this only using custom ActiveX written on C++ or Delphi or other language that does this job for VFP application or with use VFPCOM.DLL bind VFP code to some event of other COM/ActiveX object that will fire event when callback function called.

Anyway, I'm very curious why you need to handle this error? As far as I know such error is a subject of immediate code change of application or election of another tool...

In addition, I doubt you will be abnle to handle it in VFP code properly with dynamic strings handling and other dynamic memory stuff in VFP.
