分享CMFCToolBar 中频繁调用AdjustLayout()函数存在严重内存泄露，求大神帮助！
在CMFCToolBar 的AdjustLayout()函数频繁调用存在严重内存泄露！
经测试发现
AdjustSize();//有内泄露
AdjustLocations();//有严重内存泄露
函数声明：
代码中设定定时器不停地调用：
相关定义：
总之，不停地调用AdjustLayout()会有严重内存泄露！
网上说Create和CreateEx会有内存问题，按照网上说的试了没有效果！依旧内存泄露！
经测试发现
AdjustSize();//有内泄露
AdjustLocations();//有严重内存泄露
函数声明：
void CMFCToolBar::AdjustSize()；
void CMFCToolBar::AdjustLocations()；代码中设定定时器不停地调用：
nIndex = m_wndToolBar.CommandToIndex(ID_OBJECT_TESTTIME);
if (nIndex >= 0)
{
m_wndToolBar.SetToolBarBtnText(nIndex, strTimeInfo, TRUE, TRUE);
}
m_wndToolBar.AdjustLayout();相关定义：
CTestProgressToolBar m_wndToolBar;//这个在我的类里面
class CTestProgressToolBar : public CMFCToolBar
{
virtual void OnUpdateCmdUI(CFrameWnd* pTarget, BOOL bDisableIfNoHndler)
{
CMFCToolBar::OnUpdateCmdUI((CFrameWnd*) GetOwner(), bDisableIfNoHndler);
}
virtual BOOL AllowShowOnList() const { return FALSE; }
}总之，不停地调用AdjustLayout()会有严重内存泄露！
网上说Create和CreateEx会有内存问题，按照网上说的试了没有效果！依旧内存泄露！

测试发现，如果只创建一个CMFCToolBar没有发现泄漏，但是如果创建了2个，则发生泄漏，lz测试一下看看是否跟我发现的现象相同

AdjustLocations是CMFCToolBar的成员函数!而且百分之百肯定是在这里！
这样只调用AdjustLayout()有泄露！

AdjustLocations是CMFCToolBar的成员函数吗？我在MSDN的CMFCToolBar中没有搜索到，在CMFCToolBar的基类中也没有找到/
你如何确定是由这两个函数引起的？而不是由你其他绘图的代码所引起的呢？

就是定时刷新界面！有严重内存泄露！
