[ros-dev] [ros-diffs] [tkreuzer] 26564: GetNonFontObject: - OBJECTTYPE_META_DC does not SetLastError() - beautify the code a little

[James Tabor]

Hi!
    switch(dwType)
    {
+    case GDI_OBJECT_TYPE_PEN: //Check the structures and see if A & W are the same.
+    case GDI_OBJECT_TYPE_EXTPEN:
+    case GDI_OBJECT_TYPE_BRUSH: // Mixing Apples and Oranges?
+    case GDI_OBJECT_TYPE_BITMAP:
+    case GDI_OBJECT_TYPE_PALETTE:
+      return NtGdiExtGetObjectW(hGdiObj, cbSize, lpBuffer);
+
      case GDI_OBJECT_TYPE_DC:
      case GDI_OBJECT_TYPE_REGION:
      case GDI_OBJECT_TYPE_METAFILE:
      case GDI_OBJECT_TYPE_ENHMETAFILE:
      case GDI_OBJECT_TYPE_EMF:
-    case GDI_OBJECT_TYPE_METADC:
        SetLastError(ERROR_INVALID_HANDLE);
-      return 0;

This is wrong,,, you can not call NtGdiExtGetObjectW first before faulting on
GDI_OBJECT_TYPE_DC.

Normal DC's do not pass to kernel space. Please RTFM.

Thanks,
