Include header file "Gdiplus.h" in IDL file

[bidesh]

Hi all,

I have static lib which i want to convert into COM DLL. so have write an IDL file.
In this IDL file i have to define a structure which contains another structure COLOR which is defined in "Gdiplus.h".

My question is whether i can add this header file "Gdiplus.h" in the IDL file?
If yes then how. note that after including the "Gdiplus.h" i have mention its namespace also which is Gdiplus.

I have done it by including #import "Gdiplus.h" but error such as this is generated

C:\Program Files\Microsoft Platform SDK for Windows Server 2003 R2\Include\Gdiplus.h(25) : error MIDL2025 : syntax error : expecting an interface name or DispatchInterfaceName or CoclassName or ModuleName or LibraryName or a type specification near "namespace"

I am attaching the IDL file too for your reference...
Can anyone help me.

Thanks,
Bidesh
