ARe there any C# examples that show how to use Windows Media Rights Manager?

Greg Rubin · Guest

None officially, but I've been doing it with no real issues by just telling
VS2005 to include the dlls as references and it manages the InterOp for me.
If you want, I'll try to pull up some of my testing/learning code that I
wrote.

Thanks for the help I have written something very similar and am generating
the license this
part has been very straight forward but am a little confused on saving the
license. I have built
another page much like the confirm.asp sample but now am wondering how the
object can
persist and if I should include this saving of the licese on the same page.
If you have a suggestion
on how to save the license let me know.

Thanks again.

I am your post will also help others.
