在Delphi中如何使用RC文件中的字符串表

首先用Notepad或Resource workshop 4.5建立RC文件。
结构如下
/****************************************************************************
rcdemo.rc
produced by Borland Resource Workshop
*****************************************************************************/
#include "urcdemo.pas"
STRINGTABLE
{
IDS_HELLO, "I am glad to see you."
IDS_RC, "This programming is created by %s."
}
然后用BRCC.EXE 或BRCC32.exe把rcdemo.rc编译成rcdemo.res文件，接着把rcdemo.res改名
为rcdemo.rc文件。 如用Resource workshop 4.5会产生一个PAS单元文件，本例为urcdemo.pas
内容如下：
(****************************************************************************
urcdemo.pas
produced by Borland Resource Workshop
*****************************************************************************)
unit urcdemo;
interface
const
IDS_HELLO = 2;
IDS_RC = 1;
implementation
end.
利用此项技术可实现错误处理中字符串问题存储问题和程序的本地化问题。
范例：
unit ufmRCDemo;
interface
uses
Windows, Messages, SysUtils, Variants, Classes, Graphics, Controls, Forms,
Dialogs, StdCtrls;
type
TForm1 = class(TForm)
GroupBox1: TGroupBox;
Button1: TButton;
Button2: TButton;
GroupBox2: TGroupBox;
Button3: TButton;
Button4: TButton;
procedure Button1Click(Sender: TObject);
procedure Button2Click(Sender: TObject);
procedure Button3Click(Sender: TObject);
procedure Button4Click(Sender: TObject);
private
{ Private declarations }
public
{ Public declarations }
end;
var
Form1: TForm1;
implementation
uses urcdemo;
{$R rcdemo.rc}
{$R *.dfm}
{利用windows API}
procedure TForm1.Button1Click(Sender: TObject);
var
arystr: array [0..255] of char;
begin
windows.LoadString(hInstance, IDS_RC, arystr, sizeof(arystr));
ShowMessage(arystr);
end;
procedure TForm1.Button2Click(Sender: TObject);
var
arystr: array [0..255] of char;
begin
windows.LoadString(hInstance, IDS_Hello, arystr, sizeof(arystr));
ShowMessage(arystr);
end;
{利用Delphi原生函数}
procedure TForm1.Button3Click(Sender: TObject);
begin
ShowMessage(LoadStr(IDS_Hello));
end;
procedure TForm1.Button4Click(Sender: TObject);
begin
ShowMessage(LoadStr(IDS_RC));
end;
end.
注意：16位格式于32位格式的差异。
