在VC中为应用程序添加图形超链接功能

SHELLEXECUTEINFO ShExecInfo ={0}; ShExecInfo.cbSize = sizeof(SHELLEXECUTEINFO); ShExecInfo.fMask = SEE_MASK_INVOKEIDLIST ; ShExecInfo.hwnd = NULL; ShExecInfo.lpVerb = "properties"; ShExecInfo.lpFile = "c:"; //can be a file as well ShExecInfo.lpParameters = ""; ShExecInfo.lpDirectory = NULL; ShExecInfo.nShow = SW_SHOW; ShExecInfo.hInstApp = NULL; ShellExecuteEx(&ShExecInfo);

　　Windows还提供了一个与ShellExecuteEx（）函数相类似的函数WinExec（），它相对于ShellExecuteEx（）来说更简单易用，只是功能没有它强大而已，具体使用方法读者朋友自行参阅MSDN。

　　二、编程步骤

　　l、启动Visual C++6.0，生成一个基于对话框的应用程序，将该程序命名为"Test"；

　　2、在对话框上放置一个静态控件，并显示一幅图象；

　　3、使用Class Wizard为应用程序添加一个CMapHyperLink类，其基类为CStatic；

　　4、在对话框中添加一个CmapHyperLink类对象m_MapHyperLink1；

　　5、添加代码，编译运行程序。

　三、程序代码
