var
  FwMgr,Profile,FwApp: variant;
begin
  FwMgr := CreateOLEObject('HNetCfg.FwMgr');
  Profile := FwMgr.LocalPolicy.CurrentProfile;
  FwApp := CreateOLEObject('HNetCfg.FwAuthorizedApplication');
  FwApp.Name :='我的测试'; //显示名字
  FwApp.ProcessImageFileName := Application.ExeName; //要通过的程序
  FwApp.Enabled  := true;
