Looking for Windows API Definitions

[Stewart Berman]

Where is the equivalent of the Windows.h (and it's includes) for C#?

[Stewart Berman]

I took another look -- it appears to include the enums for each function.

Thanks.

If you are going to make a lot of calls into the Windows APIs, you may wish
to take a look at this site: http://pinvoke.net/

It will help you find the various [DllImport] declaractions and associated
data structures that you need to use when using Platform Invoke.

I guess you can always try MSDN:

http://msdn.microsoft.com/en-us/libr...88(VS.85).aspx
http://msdn.microsoft.com/en-us/libr...86(VS.85).aspx

Regards.

Of course, but you could easily port them to C#. I mean, AFAIK it's only
a matter of using the DllImport attribute properly.

Hello Stewart,

Thanks for using Microsoft Newsgroup Support Service, my name is Ji Zhou
[MSFT] and I will be working on this issue with you.

The .NET is a new platform with a new programming architecture. It just
provides a parallel programming API similar as the traditional Windows API.
Consequently, the recommended way is always to use the .NET platform API
instead of the native Windows API if we can.

However, if the native Windows API is very necessary in case of some
particular scenario, the .NET has provided the P/Invoke as a bridge to
communicate between the native and managed codes. That is to say, the way
of calling Windows API has changed in C#. The header file has died in the
managed world.

Rudy and others joined in this discussion have already gave some useful
links about the PInvoke signatures and samples. Actually, I want to mention
another useful tool, the P/Invoke Interop Assistant. This tool provides a
visual UI that let you select a Windows API you want to call, or native
structure you want to use, and then it will generate and report the
corresponding DllImport attribute and data structure definition to us.

You can have a look at this MSDN magazine article about how to use the
P/Invoke Interop Assitant tool,

Please let me know if you need any future assistance and I will do my best
to follow up. Have a good day!
Best regards,
Ji Zhou (v-****@online.mic rosoft.com, remove 'online.')
