注冊(cè)O(shè)CX控件

BOOL CYourClass::RegistOcx()

{

    HINSTANCE hLib = LoadLibrary("NTGraph.ocx");      //指定要注冊(cè)的ocx文件的路徑及文件名。
 
    if (hLib == NULL)
    {
         MessageBox("不能載入OCX文件!");
         return;
    }

    //獲取注冊(cè)函數(shù)DllRegisterServer地址
    FARPROC lpDllEntryPoint;
    lpDllEntryPoint = GetProcAddress(hLib,"DllRegisterServer");

    //調(diào)用注冊(cè)函數(shù)DllRegisterServer
    if(lpDllEntryPoint!=NULL)
    {
        if(FAILED((*lpDllEntryPoint)()))
        {
            //MessageBox(Handle,"調(diào)用DllRegisterServer失敗!","失敗ing..",MB_OK);
            MessageBox("OCX注冊(cè)失敗!");
            FreeLibrary(hLib);
            return;
        };
        //MessageBox(Handle,"注冊(cè)成功!","Reg",MB_OK);
        MessageBox("OCX注冊(cè)成功!");
    }
    else
        MessageBox("OCX注冊(cè)失敗!");
        //MessageBox(Handle,"調(diào)用DllRegisterServer失敗!","失敗ing..",MB_OK);

}

卸載控件

BOOL CYourClass::UnRegistOcx()

{

    HINSTANCE hLib = LoadLibrary("NTGraph.ocx");          //指定要注冊(cè)的ocx文件的路徑及文件名。
    if (hLib==NULL)
    {
        //MessageBox(Handle,"不能載入Dll文件!","失敗ing..",MB_OK);
        MessageBox("不能載入OCX文件!");
        return;
    }

    //獲取注冊(cè)函數(shù)DllRegisterServer地址
    FARPROC lpDllEntryPoint;
    lpDllEntryPoint = GetProcAddress(hLib,"DllUnregisterServer");//注意這里是DllUnregisterServer。

    //調(diào)用注冊(cè)函數(shù)DllRegisterServer
    if(lpDllEntryPoint!=NULL)
    {
        if(((*lpDllEntryPoint)()))
        {
            //MessageBox(Handle,"調(diào)用DllUnRegisterServer失??！","失敗ing..",MB_OK);
            MessageBox("調(diào)用DllUnRegisterServer失敗!!!");
            FreeLibrary(hLib);
            return;
        };
        //MessageBox(Handle,"注銷成功！","Unreg",MB_OK);
        MessageBox("OCX注銷成功！");
    }
    else
    //MessageBox(Handle,"調(diào)用DllUnRegisterServer失敗!!!","結(jié)果",MB_OK);
        MessageBox("OCX調(diào)用DllUnRegisterServer失敗!!!");

}

判斷是否注冊(cè)  

BOOL CYourClass::IsRegistOcx()

{
    HKEY hKey;    
    BOOL bPresent;    
    TCHAR szPath[_MAX_PATH];    
    DWORD dwRegType;    
    DWORD cbData   =   sizeof   szPath   *   sizeof   TCHAR;    

    if(RegOpenKeyEx(HKEY_CLASSES_ROOT,"ActiveX.ActiveXControl\\Clsid",0,KEY_READ,&hKey)!=ERROR_SUCCESS)
        return false;
    else
        return true;
  //ActiveX.ActiveXControl為控件的名稱和內(nèi)部名稱   如"NTGRAPH.NTGraphCtrl.1\\CLSID"
