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;
interface
uses
Windows, Messages, SysUtils, Variants, Classes, Graphics, Controls, Forms,
Dialogs, ExtCtrls, StdCtrls, dxCntner, dxEditor, dxExEdtr, dxEdLib,Registr
y,SConnect,DB;
const
Software='\Software\Pivot\Wages\1.0';
type
TRemoteLogin = class(TForm)
Panel1: TPanel;
Label1: TLabel;
Label2: TLabel;
Label3: TLabel;
Panel2: TPanel;
Bevel2: TBevel;
Bevel1: TBevel;
edtUserName: TdxEdit;
edtPassword: TdxEdit;
btnOk: TButton;

cbxServerIP: TdxPickEdit;

procedure LoadOptions;

end;
var

function gxRemoteLoginDialog(var AUserName, APassword: string): Boolean;
implementation
uses utMain;
{$R *.dfm}
procedure TRemoteLogin.LoadOptions;
var
reg:TRegistry;
begin
//Load the Options
reg:=TRegistry.Create;
try
Reg.RootKey := HKEY_LOCAL_MACHINE;
if Reg.OpenKey(Software, True) then
begin
cbxServerIP.Items.CommaText:=Reg.ReadString('Server');
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;
