The white balance control is not available for the selected camera
Example
This VB example uses the minimum and maximum white balance values to initialize the slider control:
Private SubForm_Load() Slider1.Min = ActiveDcam1.GetWhiteBalanceMin
Slider1.Max = ActiveDcam1.GetWhiteBalanceMax
Slider1.Value = ActiveDcam1.WhiteBalanceUB
Slider2.Min = ActiveDcam1.GetWhiteBalanceMin
Slider2.Max = ActiveDcam1.GetWhiteBalanceMax
Slider2.Value = ActiveDcam1.WhiteBalanceVR
End Sub
Remarks
If the currently selected camera doesn't support software white balance control, the method will generate an error.
