关于测试工程提示信息功能的说明
该功能的实现完全依赖于CPPToolTip类，该类可以在
http://www.codeproject.com/
上下载到。具体说明见该网站的介绍。
本程序所需要的功能是点击工具栏的“属性”按钮之后，屏幕右下角弹出测试工程的详细属性。在屏幕任何地方单击鼠标左键之后，信息提示框消失。
因此，本程序没有直接按照codeproject上的介绍那样使用CPPToolTip类，而是当点击“属性”按钮之后，调用ShowHelpTooltip函数。
在ShowHelpTooltip函数的重载版本void ShowHelpTooltip (LPPOINT pt, LPCTSTR lpszString, HICON hIcon = NULL)中，lpszString支持HTML文本，因此可以利用HTML控制显示信息的格式。
弹出的信息提示框如下图所示。
源代码如下：
///
/ MainFrm.h中定义
public
:
CPPToolTip m_toolTip;
//
显示测试属性的提示框
///
/ MainFrm.cpp中
int
CMainFrame::OnCreate(LPCREATESTRUCT lpCreateStruct)
{
……
m_toolTip.Create(
this
);
//
Adds tooltip for toolbar
m_toolTip.AddToolBar(
&
m_ProperBar);
……
}
//
显示测试工程的属性
void
CEMCView::OnEditProper()
{
//

pmfrm

,L
"

);
//

pt.x
=
rc.right;
pt.y
=

//

//
