窗口调整大小时MFC程序崩溃,错误"找不到所需的资源".

我正在开发一个SDI MFC应用程序,其中有一些自定义按钮以自定义方式绘制或者图像加载在它们之上.当正在运行的应用程序连续重新调整大小约5到10分钟时,它会因错误"未找到所需资源"而崩溃.

我已经彻底检查了代码,所有的GetDC()呼叫都跟着ReleaseDC()电话.此外,每当我DC.SelectObject(&newBrush)打电话然后恢复旧笔时,我总是保存旧的GDI对象(例如,oldBrush)DC.SelectObject(&oldBrush).

什么其他可能导致此错误的任何提示？

编辑:我使用程序Deleaker来查找程序中的GDI泄漏并删除导致泄漏的那些GDI对象.

编辑:这是AfxThrowResourceException的调用堆栈:

我确定您有GDI或其他Windows资源泄漏.消息文本来自MFC中的内部异常.

你看到的是调用AfxThrowResourceException的结果.在调试器中设置此函数的断点,您可以看到操作失败.

由于这个行为你知道你是否有内存或GDI泄漏,或者可能是其他手柄泄漏......
