Reading INI files-Delphi

The program often needs to read some user-defined values. How can this process be completed?

B/S programs generally use XML files, while C/S programs use INI files.

The previous article "C # migration of callxbflibrary-2 (call of unmanaged DLL)" is an example of C # Reading ini.

This article describes how to use Delphi to complete this process.

First, reference the unit.

 
Uses Windows, sysutils, classes, DB, ADODB, strutils, forms, inifiles;
 

"Inifiles" is the unit to be referenced.

Then, define the class variable.

 
VaR xbfini: Tinifile;
 

Finally, read/write data

1. initialize class variables

 
Xbfini: = Tinifile. Create (currentdir1 + 'cdpconfig. ini ');
 

Currentdir1 is the current directory variable.

 
Currentdir1: = extractfilepath (paramstr (0 ));
 

2. read/write data

Here is an example of reading.

 
Xbftemp: = xbfini. readstring ('filepath', '3', 'demo1. xbf ');
 

Readstring is the string method used to read INI files.

The parameters are: bar name, key name, default value
