C++ 卸载程序

目的：用C++写一个自己的卸载程序来完成程序的卸载工作，同时运行后要删除卸载程序本身，并删除卸载程序所在的文件夹。

注：在程序退出的时候写上 自己的卸载代码。

 

// FileName: Uninstall.h
#pragma onceclass CUninstall
{
private:// Exe文件名
    CString m_strExeName;// Bat文件名
    CString m_strBatName;public:// exe的路径
    CString m_strExePath;// bat的路径
    CString m_strBatPath;CString m_unInstallPath;public:// 是否已经复制到临时文件夹bool GetState (void);// 初始化void Init (void);// 卸载程序void Uninstall (void);
public:CUninstall();~CUninstall();
};
