When you call this function, the WndProc function must respond to the WM_NCCREATE message by returning TRUE. If it does not, the creation process will fail. A null handle will be returned from CreateWindowEx and GetLastError will return 0. See MSDN on WM_NCCREATE (http://msdn.microsoft.com/en-us/library/ms632635.aspx) and also WM_CREATE (http://msdn.microsoft.com/en-us/library/ms632619.aspx). You can have your WndProc call DefWindowProc, which will take care of this issue.

If the function cannot find an account name for the SID, the LookupAccountSid function fails and GetLastError returns ERROR_NONE_MAPPED. This can occur if a network time-out prevents the function from finding the name. It also occurs for SIDs that have no corresponding account name, such as a logon SID that identifies a logon session.

Constants

.

One of the many error codes returned by GetLastError, which should not be used within the .NET framework. Instead you must use Marshal.GetLastWin32Error().

.

It is documented that you should NOT use the pinvoke GetLastError() due to the fact that the runtime

Otherwise, if the function fails, the return value is zero. To get extended error information, call GetLastError.

Calling GetLastError directly via PInvoke is not guaranteed to work due to the CLR's internal interaction with the operating system. Instead, call Marshal.GetLastWin32Error.

The SetLastError flag needs to be set to true in order to retain information that would be obtained from GetLastError in the event of an error being returned.
