VC++：制作一个控件注册的小工具

　　　在平时的工作中，时常需要注册与反注册ActiveX控件，有时需要判断控件是否已经注册。

　　   所以通过查找资料编写了一个控件注册的小工具，欢迎学习交流，不当之处请多多交流。

　　　先直接上图：

　　　

　　   主要代码：

　//ControlRegisterDlg.h

　　CEdit m_EditOcxPath;
　　CString m_strOcxPath;

　　afx_msg void OnBtnSelect();
　　afx_msg void OnBtnRegister();
　　afx_msg void OnBtnUnregister();
　　afx_msg void OnBtnIsregisted();

　　

　//ControlRegisterDlg.cpp

　　ON_BN_CLICKED(IDC_BTN_SELECT, OnBtnSelect)
　　ON_BN_CLICKED(IDC_BTN_REGISTER, OnBtnRegister)
　　ON_BN_CLICKED(IDC_BTN_UNREGISTER, OnBtnUnregister)
　　ON_BN_CLICKED(IDC_BTN_ISREGISTED, OnBtnIsregisted)
