The CSVideoConferencing demo application contains basically the same code but there it works. What am I missing?         private void SetupRestrictions()         {             try             {                 LMNetSnk sink = _ServerControl.GetSubObject((int) ltmmCapture_Object.ltmmCapture_Object_Sink) as LMNetSnk;                 if (sink != null)                 {                     sink.RemoveAllRestrictions();                     Marshal.ReleaseComObject(sink);                 }             }             catch (Exception ex)             {                 MessageBox.Show(ex.Message);             }         }    Report

If not, you should not be using the value ltmmCapture_Object.ltmmCapture_Object_Sink. If it is indeed a Capture control, can you send me a small test project (not your full application) that shows this error? If you want to send the project, please put it in a ZIP or RAR file.

That call caused the filter graph to be disconnected, and caused the sink to be removed. If your problem is different, please start a new thread and give full details about the issue you're facing, or start a new support ticket by sending an email to support@leadtools.com Adnan Ismail LEADTOOLS Technical Support    Report
