MFC C ++中的内存泄漏问题 [英] Memory leak problem in MFC C++

问题描述

您好，在我的MFC C ++程序中，我的编译器检测到内存泄漏.我使用 CDC * pDC; 和 CBitmap *位图； 在我的头文件中，然后在OnInitDialog()中，我使用: pDC = new CDC;和Bitmap = new CBitmap; .我的编译器将这些检测为内存泄漏.可能是什么问题?预先感谢！

Hello, in my MFC C++ program my compiler detected memory leaks. I use CDC* pDC; and CBitmap* Bitmap; in my header file and then in OnInitDialog() i use: pDC = new CDC; and Bitmap = new CBitmap;. My compiler detected these as a memory leak. What might be the problem? Thanks in advance!

推荐答案

那是正确的.编辑您的帖子以添加详细信息，不要对自己发布虚假答案.

That is correct. Edit your post to add detail, don''t post fake answers to yourself.

问题很明显.您永远不会删除它们.如果在整个程序中都使用了它们，并且始终可见此对话框，那么这并不是真正的问题，但是您仍然应该练习清除析构函数中的所有成员变量.

THe problem is obvious. You never delete them. If they are used throughout the program, and this dialog is always visible, then it''s not really a problem, but you should still get in the practice of cleaning up all member variables in your destructor.

您正在使用
pDC =新的CDC；和位图=新的CBitmap;

使用关键字删除"释放它们.

you are using
pDC = new CDC; and Bitmap = new CBitmap;

use keyword "delete" to free them.
