在程序加载时复制文件时出现进度条

Question

好的，这里是Splashbar.pas的完整代码，仍然有三个进度条，因为我想在选择它之前先看看它们的样子。它还包括一些被禁用的东西，因为我无法让他们工作。

unit Splashbar; 

    interface 

    uses ExtActns, Windows, SysUtils, Classes, Graphics, Forms, Controls, StdCtrls, 
     Buttons, ExtCtrls, AdvProgr, ComCtrls, NetAPI32, SHFolder, WinInet, ActnList,

     UTCT1b, GIFImg; 

    type 
     TSplashBar1 = class(TForm) 
     Bevel1: TBevel; 
     ProgressBar1: TProgressBar;

     Timer1: TTimer; 
     Label1: TLabel; 
     AdvSmoothProgressBar1: TAdvSmoothProgressBar;

     DatabaseCopy: TAction; 
     procedure FormCreate(Sender: TObject); 
     procedure DatabaseCopyExecute(Sender: TObject); 
     procedure Timer1Timer(Sender: TObject); 

     private { Private declarations } 
    { procedure URLOnDownloadProgress (Sender: TDownLoadURL; 
      Progress, ProgressMax: Cardinal; 
      StatusCode: TURLDownloadStatus; 
      StatusText: String; var Cancel: Boolean) ; } 

     public { Public declarations } 
     procedure OpenSplash; 
     procedure ShowProgress; 
     procedure CloseSplash;

Answer 1

是否包含TSplashBar的单位你.dpr文件的“用途”条款中，并且它定义一个全局变量SplashBar？

Answer 2

第一个错误（W1056）： 确保

{$R *.RES} 是不是在你的DPR（项目|查看源文件）输入两次

二错误（H2077）： 别的地方在你的代码，不能用它帮助

第三个错误（W1019）： ÿ OU必须把

var 
    X: integer 

后

procedure TSplashBar1.ShowProgress; 

正确的你似乎已经定义与过程，其循环控制变量错误指示其他X某处。
