This VB example grabs a frame and saves it as a tiff file
If the Asynch property is set to TRUE, the Grab method will initiate the continuous acquisition and return after the first frame is acquired to the memory. Subsequent calls to the Grab method will return when the most recent frame is acquired to the memory.
If the Asynch property is set to FALSE, the method will initiate a single frame acquisition (One Shot mode) and return after the frame is acquired to the memory.
The FrameAcquired event will be raised after the Grab call is completed.
Note that the use of the Grab method is incompatible with the Acquire property set to TRUE. Make sure to set Acquire to FALSE when using Grab.
