The saturation control is not available for the selected camera
This VB example uses the minimum and maximum saturation values to initialize the slider control:
Private SubForm_Load() Slider1.Min = ActiveDcam1.GetSaturationMin
Slider1.Max = ActiveDcam1.GetSaturationMax
Slider1.Value = ActiveDcam1.Saturation
If the currently selected camera doesn't support software saturation control, the method will generate an error.
