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