定制远程登陆窗口

         Midas的远程登陆窗口太简单了，不能让用户选择要连接的服务器的地址
不过好在 通过以下的方法你可以修改这个登陆窗口为你自己非常喜欢
的风格，当然也因此可以记录下别人的登陆密码哦
unit utLogIn;

  TRemoteLogin = class(TForm)
    Panel1: TPanel;

var

function gxRemoteLoginDialog(var AUserName, APassword: string): Boolean;

procedure TRemoteLogin.LoadOptions;
var

begin
  //Load the Options
  reg:=TRegistry.Create;

    if Reg.OpenKey(Software, True) then
   begin

      Reg.CloseKey;
    end;
  finally
    Reg.Free;
    inherited;
  end;
end;
procedure TRemoteLogin.SaveOptions;
var
  reg:TRegistry;
begin
  //Load the Saved Options
  if (cbxServerIP.Items.IndexOf(cbxServerIP.Text)=-1) then
    cbxServerIP.Items.Insert(0,cbxServerIP.Text);
  reg:=TRegistry.Create;
  try
    Reg.RootKey := HKEY_LOCAL_MACHINE;
    if Reg.OpenKey(Software, True) then
   begin
      Reg.WriteString('Server',cbxServerIP.Items.CommaText);
      Reg.CloseKey;
    end;
  finally
    Reg.Free;
    inherited;
  end;
end;
function gxRemoteLoginDialog(var AUserName, APassword: string): Boolean;
begin
  with TRemoteLogin.Create(Application) do
  try
    Caption := '远程登录';
    LoadOptions;
    edtUserName.Text := AUserName;
    Result := False;
    if AUserName = '' then ActiveControl := edtUserName;
    if (   cbxServerIP.Items.Count=0) then
      cbxServerIP.ItemIndex:=-1
    else
      cbxServerIP.ItemIndex:=0;
    if ShowModal = mrOk then
    begin
      AUserName := edtUserName.Text;
      APassword := edtPassword.Text;
      frmMain.Connection.Host:=cbxServerIp.Text;
      Result := True;
      SaveOptions;
    end;
  finally
    Free;
  end;

end;
end.
最关键的一句是：
initialization
  RemoteLoginDialogProc := gxRemoteLoginDialog;
