How to use a Win32 API inteface in C#?

[nox]

hi,

for my last question I didn't get any answer, so I'll try to define
the question in another way...

the shell32.dll exposes an interface called ITaskbarList which has a
few functions to manipulate taskbar buttons

I know how to use the a "normal" API function with DllImport, but I
can't figure out how to implement this interface...

can you help me please?

Hi,

Have a look at http://msdn.microsoft.com/en-us/library/bb774652(VS.85).aspx

It says: You do not implement ITaskbarList; it is implemented by the
Shell

Here you can find more on using the taskbar

Hope this helps,
Joachim

actually I know that I should not implement it, I've the first page in
the documentation (thx for the second link, this I haven't seen
yet)...

I just don't know how to use this interface in my application

ITaskbarList is not Win32 API - it is COM.

It seems to be a bit tricky to use from .NET though.
