method, Method and Function Index
Sets a message trap.
Syntax:
object.SetTrap(Message
As Long)
The SetTrap method syntax has these parts:
| Part |
Description |
| object |
The name of an object in the Applies to list. If object is
a SubClasser object, then the object must be declared using WithEvents
in order to receive the TrapMessage event. |
| Message |
Message identifier of the message to be trapped. |
Remarks:
Setting a message trap for a particular message identifier will cause a
Subclasser object or PowerForm control to raise a TrapMessage each time the
subclassed window receives a message with that identifier.
A TrapMessage event will not be raised for messages which are handled
by the Subclasser object or PowerForm control.
The following messages are handled by the Subclasser object and PowerForm
control, and cannot be used with SetTrap:
