I don't see how the PROGID would be consistant as the controls could each be
in a different OCX file.

Also, the VFP class that is bound to it would have to have methods with the class
names in them, as in the code below. The OCX class name is part of the method names.

Therefore, I don't see how VFP could use a single class that would bind to any of the
CV classes, even if they had the same interface.

I'm open to suggesstion.

DEFINE CLASS myclass AS session OLEPUBLIC

	IMPLEMENTS _rptAccountStatus IN "NSAcctStatus.rptAccountStatus"

	PROCEDURE __rptAccountStatus_PassArray(aHeaders AS VARIANT @, aValues AS VARIANT @) AS VOID
	* add user code here
	ENDPROC

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

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

ENDDEFINE
<pre>

I hadn't yet installed the Help 2.0 compiler on this particular install and Help Builder would simply not compile. Similar issue. Once compiled the class runs just fine on another system if the Help 2.0 compiler doesn't exist. I used a PROGID but I think the same is true for the physical filename.
