Brian, I hate to keep bothering you but can I ask another quick question ?

I tried everything I can think of and VFP never sees the event ever....

So I decided to make sure that VFP could see the events in a simple single threaded ocx written with the MFC ActiveX Control Wizard. I created a brand new C++ Active X Control Project with only 2 propertys and 1 event and in the OnChange of one of the properies the event is fired but again vfp never sees the event firing ??? Does this make any sense to you ? On a form the event never fires but I can read and write the properties of the control.... But if I try to instantiate in code I can't even read or write props as the control sends a "Catastrophic Failure" OLE error ?

If I try this code:

Public oMyObj 

oMyObj = Crea("VFPTEST.VfpTestCtrl.1")
Vfpocxx=Newobject("myclass")

Eventhandler(oMyObj,Vfpocxx)

oMyObj.firstName = "Greg"    * <-- This line provokes a "Catastrophic Failure" 

oMyForm = Crea("myForm")
oMyForm.Show()


x=NEWOBJECT("myclass")

DEFINE CLASS myclass AS session OLEPUBLIC

	IMPLEMENTS _DVfpTestEvents IN "Z:\MIS\C++\VFPTEST\DEBUG\VFPTEST.OCX"

	PROCEDURE _DVfpTestEvents_mitaiEvent() AS VOID
	* add user code here
	ENDPROC

	PROCEDURE _DVfpTestEvents_Click() AS VOID
	* add user code here
	ENDPROC

	PROCEDURE _DVfpTestEvents_myClickIn(xPos AS Number, yPos AS Number) AS VOID
	* add user code here
	ENDPROC

ENDDEFINE


Define Class myForm As Form
	WindowType = 1
	AutoCenter = .T.

Enddefine

Accessing any of the properties gives this "Catastrophic Failure" error but only when instantiated in code. BTW it does the same thing even if Eventhandler() is not used...

Does this mean anything to you ???

Thanks

They post a message which in turn is handled by your windows class which then fires the events on your control via the pointer in which you set earlier.
