Question

I am using some native methods to bind to running objects in a COM-based application. One of the methods is the CreateBindCtx, which has the following signature (from MSDN)

WINOLEAPI CreateBindCtx(DWORD reserved, LPBC FAR * ppbc) 

I have defined the wrapper to be

public static extern void CreateBindCtx(int reserved, out IBindCtx ppbc); 

But FXCop is complaining about the void return type. What should the .Net/C# data type be?

Answer 1

[DllImport('ole32.dll')] static extern int CreateBindCtx(uint reserved, out IBindCtx ppbc); 

One of the best places for pinvoke info is PInvoke.Net
