Question:  My Visual Basic application draws the frames from a Passthru operation in the controller's window. I would like to acquire some frames using PassthruSnapshot and display them in a PictureBox window, but am getting errors with my DT3131, DT3132 or DT3133.

 

Answer:  You cannot draw your snapshot while the Passthru operation is running. Before you call the DrawAcquiredFrame for the snapshot, make a call to StopPassthru. After drawing, then you can restart the Passthru operation. Updated: 10/24/02.
