ambiguous data types

Hi,

Under VC++.net, if i include windows.h, and compile my application, i
have several data types ambiguous, like IDataObject, IMessageFilter,
IDropTarget,...

so it means that they are defined in windows.h but also in some other
namespaces.

how can i do to still have my windows.h included and avoiding ambiguous
definition ? and thus without undefining all ambiguous data type ?

thx.

You're going to have to show some minimal amount of code to reproduce the
problem that you're seeing.

Generally, I think the experience is better if you do NOT include windows.h
in modules that are compiled with /clr - keep it limited to purely native
modules.

Here is the ARDLLWrapper.h file that i include in my main.h file
When i compile this file with its relative *.cpp, it's ok, but when i
try to compile my application. It generates the error i meant before.
it seems that it is known problem, but i did not find the solution on
internet for now.

do you have an idea ?
