The GetState method retrieves the current state of the filter graph.
objGraph.GetState( msTimeout As Long, ByRef State As Long)
Specifies the duration to wait for the graph to complete a state transition, in milliseconds.
Variable that receives the current state. When the method returns, this variable will have one of the following values.
This method does not return a value.
If the filter graph is transitioning to a new state, the method waits for the transition to complete, up to the duration specified by the msTimeout method. If this duration expires before the transition is complete, the method returns the new state and sets Err.Number to 567 (VFW_S_STATE_INTERMEDIATE).
The following example checks whether the filter graph is stopped:
Dim state As Long mGraph.GetState 100, state If state = 0 Then ' Filter graph is stopped. End If
