Example

Private Sub ActiveDcam1_FrameAcquired()

Label1.Caption = ActiveDcam1.GetPixel(16, 32)

End Sub

Remarks

One of the following conditions must be met, before the FrameAcquired event will be fired:

The Grab method has been called.

The FrameAcquired event is fired from the interface thread to provide compatibility with all types of ActiveX containers. For applications created in VB.NET, C# and C++ it is recommended to use the FrameAcquiredX event.
