When calling this API, set the first byte of reportBuffer to the feature report that you want to get. When the function call returns, the rest of the array will be filled with the feature report data.

I am involved in a project whereby I have to use a methods from a Win32 API (wrg303.dll). I have tried using p/invoke wizard, but it didn't gave the right answer.

The rapi.dll section needs to be corrected. Rapi is not for running on the .NET Compact Framework, but rather for desktop applications. It does not appear possible to edit this part of the page.

Great idea, thanks for creating the site. However, it does have rendering problems on Mozilla (Firefox 0.8 on Win XP to be exact). The directory tree (advapi32, gdi32 etc.) is misplaced (overlaps the "Directory" label) and I can't get them to expand.

One question: The APIs here appear to be machanically created from some other source - from things like "System.Windows.Forms.NativeMethods"? The functions are present, but not the structures and data types used in the params. Any plans to do a mechanical dump of the structures as well? The real magic of marshalling is getting the param types set up correctly, which for structures can be quite a pain.

You should also check out these automatically generated PInvoke stubs which covers much of the WIn32 API

Add all the WLAN apis from

^deadlink, search for "wlan api site:codeplex.com" on google

Just wanted to say "Thanks! This site ROCKS!" This has made working with the Windows API in C# a breeze.

Hi, would tapi32.dll functions be available anytime? - Ashish

Is someone going to add the module for dwmapi.dll?
