In case you missed it in another thread here today, there is a Gotcha in using a BINDEVENT for an event where VFP passes parameters to. Take the MouseMove event for example. Edit the MouseMove, and you see a parameter statement:

LPARAMETERS nButton, nShift, nXCoord, nYCoord

So, when you BINDEVENT any event to which VFP passes parameters, the delegate method or procedure needs to lead with a parameter statement with the same number of parameters. So the MyMouseMove code in the BINDEVENT example below must have a parameter statement in order to avoid an error:

BINDEVENT(THIS, 'MouseMove', THISFORM, 'MyMouseMove')

BTW, this is documented in the VFP Help CHM file.
