Hello People,

i send in first an example.

IAMCameraControl icc = (IAMCameraControl)capFilter;               
CameraControlFlags f;                             
int lValue;               
int hr = icc.Get(CameraControlProperty.Zoom, out lValue, out f);

The Result of this test is = -2147023728.

It seems as if only Exposure and Focus are supported.

There is a possibility the function zoom (digital zoom) in a c# project to reaching?

I cannont understand why the IAMCameraControl interface is not supported completely.

It`s very important for me to mention this function.

I have tryout different drivers but nothing helped.

I hope somebody can help with extendet informations or a little solution in c# to reaching the Zoom function of this Camera

Here is the ComImport

    public enum CameraControlFlags
    {
        None = 0x0,
        Auto = 0x0001,
        Manual = 0x0002
    }

    /// <summary>

    public enum CameraControlProperty
    {
        Pan = 0,
        Tilt,
        Roll,
        Zoom,
        Exposure,
        Iris,
        Focus
    }
