关于“系统资源”泄露的问题，来者有分

[pf_ma]

一程序，在 Win98上运行，每次运行完，内存正常，但系统资源都有泄露。
请问什么可能造成“系统资源”泄露，是 HANDLE 没有关闭？COM 没有 Release?
还是什么？

[askquestion1978]

有很多原因可能造成这种结果
你说的2种也是，还有new没有del得，忘了DeleteObject得，还有些指针的使用有问题的，等等等等啦，反正是有许多

下面为某次浏览找到的win32资源的分配清除文档，只简单的翻译了几个文字。该文档对防止资源泄露有很大帮助。抱歉一贴上就串了。

注：
* 位图资源在释放的时候必须从选中它的dc中脱离。
% 当菜单失去焦点和窗口不再关联或者应用程序结束的时候占用资源必须被释放。
@ dc被释放前必须和它关联（选中）的位图取消联系
# 如果脱字符指定了位图，位图必须被释放
& 对deleteobject的调用不会销毁常规的stockobject（系统内定资源）
