Strings are stored independently in the application. The application is loaded only when resources are used.
In addition to memory saving, strings can also be used for translation. Some Chinese software use strings. Edited word
Put the string in a text file, you can use: file-> New-> text in Delphi to edit the string file, word
The format of the string file is as follows:
Stringtable
Begin
1. "book"
2. "apple"
3. "desk"
4, "pen"
5. "computer"
End
After editing the string file, select Save As. Note that you should change the file type to the resource compilation file (. RC), this is not a resource file, it must be compiled to become a resource file (. res ). The compiling command is brcc32 at the DOS prompt, and its path is D: Program filesborlanddelphi4binrcc32.exe. For example, the above string resource compilation file name is strres. RC: Enter brcc32 mydirstrres at the DOS prompt. RC; after compilation, a file named strres is generated. res resource file, which can be used to access string resources. For more information, see the following example:
Unit teststr;
Interface
Uses
Windows, messages, sysutils, classes, graphics, controls, forms, dialogs, stdctrls;
Type
Tform1 = Class (tform)
Button1: tbutton;
Label1: tlabel;
Procedure button1click (Sender: tobject );
Procedure formcreate (Sender: tobject );
Private
Count: integer;
Public
End;
VaR
Form1: tform1;
Implementation
{*. DFM}
{Strres. Res}
Const
Wordcount = 5;
Procedure tform1.button1click (Sender: tobject );
VaR
Strword: string;
Begin
If count> wordcount then
Begin
Count: = 1;
End;
Strword: = loadstr (count );
Label1.caption: = strword;
Count: = count + 1;
End;
Procedure tform1.formcreate (Sender: tobject );
Begin
Label1.caption: = loadstr (1 );
Count: = 2;
End;
End.
The constant wordcount in the program is used to record the number of strings in the string resource file, and the variable count is used to record
String number. After the program runs, click the button1 button. Each word in the string resource file is displayed cyclically.
String.

Different from other resources, string resources cannot be directly edited. You must first compile a text file in the format, and then use
Compile it into source files in sequence. The following is a simple example. First, compile a file lb. RC in a text editor,
The content is as follows:
Stringtable
Begin
1, "start"
2. "quit"
End
Find the brcc32.exe file in the binsubdirectory of delphiand compile it. The command format is brcc32.
LB. RC: After compilation, a resource file lb. Res is generated. To use this resource file, you need to import the resource file in the cell file imple.
The starting part of mentation includes the resource file <$ R lb. Res>. In this example, the above string is used
The command button replaces the caption settings. The function used is the Windows API function loadstring, and the following is the instance used:
// In the formcreat process:
VaR
Txtcaption: array [0 .. 255] of char;
Begin
If loadstring (hinstance, 1, txtcaption, sizeof (txtcaption)> 0 then
Begin
Btnstart. Caption: = strpas (txtcaption );
End;
End;
// In the btnstartclick process:
VaR
Txtcaption: array [0 .. 255] of char;
Begin
If loadstring (hinstance, 2, txtcaption, sizeof (txtcaption)> 0 then
Btnstart. Caption: = strpas (txtcaption );
End;
In this way, various attributes can be changed while the program is running, without the need for a string to appear in the program. If you use another
The Delphi function loadstr will be simpler:
VaR
Txtcaption: string;
Begin
Txtcaption: = loadstr (2 );
If txtcaption <> ''then
Begin
Btnstart. Caption: = txtcaption;
End;
End;
Perhaps we can see from the above process that using 123 to identify a string is a little simple, it is easy
So what should I do? We can use a string method like C ++ to predefine an ID for each string,
For example:
Const
IDC-Start = 1;
IDC-exit = 2;
Of course, you should put it in a unit (similar to C ++. h file), and then uses it in the unit in use.
Yes. Is the application very nice?
Txtcaption: = loadstr (IDC-exit );
