通过代码动态注册OCX控件

 

1.       在APP初始化中：

if (FAILED(OleInitialize(NULL)))

   {

      AfxMessageBox("OLE initialization failed.Make sure that the OLE libraries are the correct version.") ;

      return FALSE ;

   }

2．在需使用的对话框及程序开头处加入

#ifdef _WIN32

#define LOADLIBRARY_FAILED(x) (x == 0)

#else

#define LOADLIBRARY_FAILED(x) (x <= HINSTANCE_ERROR)

#endif

 

//定义函数地址

STDAPI DllRegisterServer(void) ;

STDAPI DllUnregisterServer(void) ;

typedef HRESULT (STDAPICALLTYPE *CTLREGPROC)();

 

3.       定义注册函数

BOOL CNetMeetDlg::Register(CString strOcx)   //strOcx为需注册的OCX名称

{

              BOOL bResult = FALSE;

              HMODULE hModule = ::LoadLibrary(strOcx) ;

              if (LOADLIBRARY_FAILED(hModule)) return FALSE ;

      

              //获得注册函数地址

              CTLREGPROC DLLRegisterServer =

            (CTLREGPROC)::GetProcAddress(hModule,"DllRegisterServer" ) ;

              if (DLLRegisterServer != NULL)

              {

                     HRESULT regResult = DLLRegisterServer() ;

                     bResult = (regResult == NOERROR) ;

              }

              ::FreeLibrary(hModule) ;

        return bResult;

}

 

4.在需注册的地方加入Register(“name.OCX”);
