I'm writting a COM componant in C++/IDL.
This componant is using in C# project, and I want to use
System.Drawing.Bitmap
In my IDl file I writed importlib("System.Drawing.tlb");
On function declaration is [id(5)] HRESULT image([out, retval] _Bitmap
**ppImage);
But how I can create initiaze it correctly ?
How I can cast an System::Drawing::Bitamp^ in _Bitmap* ?

If you have sample or some help.

Thanks

if you have System::Drawing::Bitamp^ already, then you are writing a managed
assembly. you can reference the assembly you created in C#
