ClassBeforeChange

The ClassBeforeChange class function is called for each object to be assigned a new class.

Syntax
ClassBeforeChange(Cancel, NoClassTerminate)
Return value
No
Parameter
Use	Name	Type	Passing	Description
Required	Cancel	Boolean	ByRef	True prevents the change to another class.
Required	NoClassTerminate	Boolean	ByRef	True prevents the call of ClassTerminate.

Notes

The ClassBeforeChange function is still running in the object whose class is to change. If, when the function is executed, it is determined that a change should be rejected, the Cancel parameter can be set to True. This prevents the object change from continuing.

If you want to prevent the ClassTerminate function of the object from being triggered when an object is reselected, the NoClassTerminate parameter must be set to True.
