           Summary: Incorrect FindWindow/GetLastError error result when
                    window not found
           Product: Wine
           Version: 1.1.2
          Platform: PC
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: -unknown
        AssignedTo: wine-bugs at winehq.org
        ReportedBy: vesselinpeev at hotmail.com


The following program (compiled to a Win32 binary) prints "Window not found
(expected result)" under Microsoft Windows (tested with Vista), whereas it
prints "Unexpected error, GetLastError() return value: 1407" when ran under
Wine (tested with Wine 1.1.2).

It seems that FindWindow does not set the correct error value
(ERROR_FILE_NOT_FOUND) when it doesn't find a window.

#include <windows.h>
#include <stdio.h>

int main()
{
  HWND hWnd = FindWindow("SomeWindowThatDoesNotExist", NULL);
  if(hWnd) {
    printf("hWnd not NULL");
  }
  else {
    DWORD dwResult = GetLastError();
    if(dwResult == ERROR_FILE_NOT_FOUND) {
      printf("Window not found (expected result)\n");
    }
    else {
      printf("Unexpected error, GetLastError() return value: %lu\n", dwResult);
    }
  }
  return 0;
}
