我把登錄視窗不管從Project中移走，還是從Project Option 的自動建立視窗中移到可用視窗里，都在form2:=form2.create(nil)出錯，謝謝你再指教

我的做法如下： ------------------------------------------------------------- program GM; uses Forms, Windows, Messages, SysUtils, Dialogs, Controls, FOR_DEAL in 'FOR_DEAL.PAS' {Form_Deal}, FOR_LOGO in 'FOR_LOGO.pas' {Form_Logo}, FOR_LOGI in 'FOR_LOGI.pas' {Form_Login}, {$R *.res} begin try //建立LOGO畫面 Form_Logo := TForm_Logo.Create(Application); Form_Logo.Show; Application.Initialize; //建立主視窗 Application.CreateForm(TForm_Deal, Form_Deal); //隱藏主視窗 Form_Deal.Hide; //建立登入畫面 Form_Login := TForm_Login.Create(Application); //登入畫面設定ShowModal Form_Login.ShowModal; finally //釋放LOGO畫面。 Form_Logo.Free; //判斷登入是否正確，否則直接關閉程式。 //登入時之確定鈕於“名稱”及“密碼”都正確時才顯現 //BTNOk.Enabled := True; if (Form_Login.ModalResult = mrYes) then begin Form_Deal.Show; Application.Run; end; end; end. ----------------------------------------------------------- 試試看吧！
