Lane、PHY和Preset Value Bit 每个Lane支持不同的传输速度和带宽，例如PCIe 3.0中，一个Lane的传输速度可以达到8 GT/s（Giga Transfers per second），也就是1 GB/s（GigaBytes per second）。Preset Value Bit（预置值位）是在PCIe 3.0的Lane上新引入的一种机制，用于优化信号传输质量。PCIe设备可以包含多个Lane，例如x1、x4、x8、x16等，表示该设备同时使用的Lane数目，比如x16表示该设备采用了16个Lane，具有更高的传输速度和带宽。阅读详情

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：

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！

// 加载工具栏:

	m_wndToolBar.Create(this, 

		WS_CHILD | WS_VISIBLE | CBRS_TOP | CBRS_GRIPPER | CBRS_TOOLTIPS | CBRS_FLYBY | CBRS_SIZE_DYNAMIC | CBRS_FLOATING, 

		IDR_TOOLBAR_TMSSVIEW);

	m_wndToolBar.LoadToolBar(IDR_TOOLBAR_TMSSVIEW, 0, IDR_TOOLBAR_TMSSVIEW, TRUE, 0, 0, IDR_TOOLBAR_TMSSVIEW);

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！

	//nIndex = m_wndToolBar.CommandToIndex(ID_OBJECT_TESTTIME);

 //	if (nIndex >= 0)

 //	{

 //		m_wndToolBar.SetToolBarBtnText(nIndex, strTimeInfo, TRUE, TRUE);

 //	}

 

 	m_wndToolBar.AdjustLayout();

这样只调用AdjustLayout()有泄露！
当你

class CTestProgressToolBar : public CMFCToolBar

	virtual void OnUpdateCmdUI(CFrameWnd* pTarget, BOOL bDisableIfNoHndler)

	{

		CMFCToolBar::OnUpdateCmdUI((CFrameWnd*) GetOwner(), bDisableIfNoHndler);

	}

这样时，自己重写就不会出现内存泄露，注释那两个函数！
可是工具栏就不位置还有图片文字就刷不出来了！

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！

CMFCToolBar 中频繁调用AdjustLayout()函数存在严重内存泄露，求大神帮助！
