If you have the Multimedia V15 SDK installed, this project should compile with no changes. Otis Goodwin LEAD Developer Support    Report

There are numerous tools on the NET such as "InstantVB" which customers have used in the past to convert snippets or projects. The evaluation COM object and release COM object have different class ID's so you may need to remove and re-add the LTMM references to compile. Otis Goodwin LEAD Developer Support    Report

06-01-2007, 5:22 motyka Joined on 06-01-2007 Posts 5 Re: Motion Detection Filter in DOTNET C# Hello, I've got a problem with motin detection filter in C# (Visual Studio 2005) Filter graph hangs on callback. When I don't use callback, the filter wokrs fine, (the motion detection areas are visible on video). But when I try to use callback - the graph hangs. My code: ILMVMtnDet motionDetFilter = new LMVMtnDetClass(); // filter declaration .. then after I add filter to graph and connects with other filters I do some configuration:         private void ConfigureMotionDetection(ILMVMtnDet motionDetection)         {             m_MotionDetectionCallback = new MotionDetectionCallback();             motionDetection.AutoStart = true;             motionDetection.CallbackObj = new MotionDetectionCallback();         } The callback class:     public class MotionDetectionCallback : ILMVMtnDetUserCallback     {         public MotionDetectionCallback()         {         }         ~MotionDetectionCallback()         {         }        public int CallbackProc(int lEvent, int pFrame, int lWidth, int lHeight, int lBitCount, int lFrameSize, bool bTopDown)         {             System.Diagnostics.Debug.WriteLine(lEvent);             return 0;         }     } Any ideas, pliz? Regards, Roman.    Report

Please send a small sample project (not your entire project), and I will debug your project here. Otis Goodwin LEAD Developer Support    Report

But during building that sample I've probably found the reason of such behavior. If you compile that project with USEWINFORM directive, which starts Winform, the callback will be ok, but if you don't use that directive (pure console application) the callback hangs:         static void Main()         { #if USEWINFORM             Application.Run(new Form1()); // then start button - it is ok #else             Console.WriteLine("Press eneter to start it");             Console.ReadLine();             m_play = new DxPlay();             m_play.Start();             Console.WriteLine("Press eneter to stop it");             Console.ReadLine();             m_play.Stop(); #endif         } It may have it's origin in 'test/warning' which fires motion detection filter, and it might hangs when no windows message loop is present (or sth. like that). I believe that filter without that warning window wouldn't hangs on callback, could you confirm that? Regards, Roman.    Report

If you are using a console application, you can probably add System.Windows.Forms and use DoEvents to process the messages. Otis Goodwin LEAD Developer Support    Report
