However, tests indicates that the upon return, the contents of both iconPath and index parameters are the same after the function returns successfully.

Be careful with the string structure fields: UnmanagedType.LPTStr will be marshalled as unicode string so only the first character will be recognized by the function. Use UnmanagedType.LPStr instead. [Tested on Win7]

The hwnd field should be the handle of the required parent calling window (see http://msdn.microsoft.com/en-us/library/bb762169.aspx). passing in <parent window>.Handle (in C#) works in XP, but in Vista it does not. What works on Vista is passing in 0 (IntPtr.Zero). I have tested this on WP SP2 and it works there as well.
