在程序中，你可以使用
UINT WinExec(
  LPCSTR lpCmdLine,  // command line
  UINT uCmdShow      // window style
);
来调用其他应用程序和命令，例如：
WinExec("regsvr32 your_ocx_name.ocx",SW_SHOW);

Answer 3

register:  regsvr32 *.ocx
unregister:regsvr32 /u *.ocx

BOOL CSecuryEntryDlg::RegDllControl(LPCTSTR pszDllName)
{
HINSTANCE hLib = LoadLibrary(pszDllName);
    if (hLib <(HINSTANCE)HINSTANCE_ERROR)
    {
AfxMessageBox(_T("dll file can't be import!"),MB_OK,NULL);
return 0;
}
    //get DllRegisterServer address
    FARPROC lpDllEntryPoint; 
    lpDllEntryPoint = GetProcAddress(hLib,_T("DllRegisterServer"));
    //DllRegisterServer
    if(lpDllEntryPoint!=NULL)
    {
         if(FAILED((*lpDllEntryPoint)()))
         {
              AfxMessageBox(_T("DllRegisterServer Failed！"),MB_OK,NULL);
              FreeLibrary(hLib);
  return 0;
         }    }
    else
    AfxMessageBox(_T("DllRegisterServer Failed!"),MB_OK,NULL);
return 1;
}BOOL CSecuryEntryDlg::UnRegDllControl(LPCTSTR pszDllName)
{
HINSTANCE hLib = LoadLibrary(pszDllName);
    if (hLib <(HINSTANCE)HINSTANCE_ERROR)
    {
AfxMessageBox(_T("dll file can't be import!"),MB_OK,NULL);
return 0;
}
    //get DllUnregisterServer address
    FARPROC lpDllEntryPoint; 
    lpDllEntryPoint = GetProcAddress(hLib,_T("DllUnregisterServer"));
    //DllUnregisterServer
    if(lpDllEntryPoint!=NULL)
