DOCUMENT:Q119453 26-JUN-1999 [win16sdk] TITLE :PRB: GDI Heap Fills Up While Playing a Metafile PRODUCT :Microsoft Windows Software Development Kit PROD/VER:WINDOWS:3.1 OPER/SYS: KEYWORDS:kb16bitonly kbSDKWin16 ====================================================================== 3.10 WINDOWS kbprg kbprb ------------------------------------------------------------------------------- The information in this article applies to: - Microsoft Windows Software Development Kit (SDK) 3.1 ------------------------------------------------------------------------------- SYMPTOMS ======== During the playback of a metafile or printing, the GDI heap fills up and it is not possible to create additional GDI objects. CAUSE ===== This filling of the GDI heap can be caused by a metafile that does not contain any DELETEOBJECT metafile records. The GDI objects created during the metafile playback never get deleted, which fills up the GDI heap. An application that prints without using banding in Windows version 3.1 causes a metafile to be created on behalf of the application. The problem listed above then occurs. The DELETEOBJECT metafile record is a new feature developed for Windows version 3.1. This record is used to record DeleteObject() calls into the metafile, so that the specified GDI object is deleted during playback of the metafile. If you call DeleteObject() on an object that is currently selected into a metafile Device Context (DC), a DELETEOBJECT record will not be recorded into the metafile. The documentation for DeleteObject() states that the object must not be selected into a DC. RESOLUTION ========== Make sure to deselect the object in your metafile DC before calling DeleteObject() to delete the object. For additional information about calling DeleteObject() for a metafile object, please see the following article(s) in the Microsoft Knowledge Base: Q68296 Windows 3.x Metafiles Support DeleteObject() STATUS ====== This behavior is by design.
