Form1 > form2 在 QuickRep 預覽按 Close 是正常
,但按鍵盤 Esc 會出現 Access violation address 00403955 in module 'aproject.exe' read of address 0000032 錯誤
網路查了很多類似 access ....錯誤資訊, ,還是無解,懇請前輩幫忙

unit aUnit1; // Form1
interface
uses
Windows, Messages, SysUtils, Variants, Classes, Graphics, Controls, Forms,
Dialogs, StdCtrls;

type
TForm1 = class(TForm)
Button1: TButton;
procedure Button1Click(Sender: TObject);
private
{ Private declarations }
public
{ Public declarations }
end;

var
Form1: TForm1;
implementation
uses Unit2;
{$R *.dfm}

procedure TForm1.Button1Click(Sender: TObject);
begin
form2.QuickRep1.Preview;
end;
end.

end;

end.

我後來測試與各位分享 使用 delphi 7
我是 QuickRept 4.07 up to QuickRept5.02 後所發生的
後來移除 QuickRep5.02 後來就正常

可能在升級的後所造成的
所以升級問題還是不少
因為最近使用一些升級有感而言
原 FileZilla_Server-0_9_10 up to FileZilla_Server-0_9_51後
中文文件存取檔案,多是亂碼,再傳送時就會卡在一半不動
後來回覆到 FileZilla_Server-0_9_10 就正常
網路似許多類似問題,但我測了許多網路上做法
還是失敗,花費太多時間,還是用回原來就 ok
