>Which is how I do it. In my custom form baseclass, I have a property called oCaller to hold a reference to the calling program. In the init I have this code:

I haven't re-tested this recently, but as I recall, ActiveForm can only be used in Form's Load, Init is too late.
If it's not broken, fix it until it is.
