ActiveDcam1.Acquire=True
HScroll1.Value = ActiveDcam1.Pan
HScroll1.Min = ActiveDcam1.GetPanMin

End Sub

Private Sub HScroll1_Scroll()
ActiveDcam1.Pan = HScroll1.Value
End Sub

Remarks

This property provides adjustment of the camera's pan feature. Depending on the camera model, it can control the mechanical pan by physically moving the camera in the horizontal plane or the electronic pan by choosing the horizontal position of the effective image area on a CCD sensor.

The valid property range is reported by the GetPanMin and GetPanMax methods. Note that the property is available only if the currently selected camera supports software pan control.
