Hi there,

can anybody show me an easy programm that uses directshow methods with a CLR/WinForm App? I've already made some successful samples using directshow under Win32/WinForm App.
But when i made the same thing in CLR/WinForm, it has always errors, for example like that:

VB

1>TEST.obj : error LNK2020: Unresolved token (0A000016) IID_IMediaEvent.
1>TEST.obj : error LNK2020: Unresolved token (0A000017) IID_IMediaControl. 
1>TEST.obj : error LNK2020: Unresolved token (0A000019) CLSID_FilterGraph.
1>TEST.obj : error LNK2020: Unresolved token (0A00001A) IID_IGraphBuilder.
1>TEST.obj : error LNK2001: Unresolved extern symbol "IID_IMediaEvent".
1>TEST.obj : error LNK2001: Unresolved extern symbol "IID_IMediaControl".
1>TEST.obj : error LNK2001: Unresolved extern symbol "IID_IGraphBuilder".
1>TEST.obj : error LNK2001: Unresolved extern symbol "CLSID_FilterGraph".
1>c:\dokumente und einstellungen\cmadmin\eigene dateien\visual studio 2010\Projects\TEST\Debug\TEST.exe : fatal error LNK1120: 8 Unresolved extern references.

although i did add strmiids.lib, quartz.lib and ole32.lib before.

Thank you very much!

Solution 1

Have a look at: __uuidof Operator[^] and #pragma managed[^]

As long as you have something that works for Win32 this should help you to get things working with managed code.
