Das Problem wird im Artikel sogar angesprochen, hast du wirklich die
Dll daraus genommen?
Zitat:
Unfortunately, the embedded TLB has a bug for methods passing a window
handle. I used ILDASM to get the
IL code of the interop assembly, then I changed all incorrect occurances of 'valuetype _RemotableHandle&' to 'native int', then finally compiled back to an assembly with ILASM. This repaired
DLL is included in the download as WIAVIDEOLib.dll.
