thank you. nice to hear form you again with advice.
I failed to find docobj.h in my system and apparently it comes with inet
sdk
which I did not download. I will try look for more detail on the .h file
however I am not all familar with C++ to C# ; may be able do some struct
conversion and simple type though.
I was copying some code from kb to enhance the built-in webbrowser control
by exposing IWebBrowser2

GS,
Without seeing the relevant code (a short, complete example would be
better), it's difficult to say.
However, the errors indicate that something else is going on. First, it
seems you are trying to access something that is not visible to your
code.
The NativeMethods type in the System.Drawing namespace is more than
likely
internal to System.Drawing.dll, so I'm not surprized about this.
What exactly are you trying to do? Are you trying to use the
OLECMDID
type in a definition of the IOleCommandTarget and IWebBrowser2 interfaces
that you are declaring yourself? If so, you will have to declare this type
yourself, which isn't too hard given the header file (docobj.h).
