There are many ways to edit an INI file in the machine. Following article describes editing INI file using WiseScript. Using WiseScript one can Add/modify/delete a section and its content.

Introduction

INI files are simple text files with a basic structure that contain configuration information. They are commonly associated with Microsoft Windows, but are also used on other platforms. The name "INI file" comes from the filename extension usually used, ".INI", that stands for "initialization".

Format of .INI Files

INI files contain one or more sections. Each section begins with a section name, which is followed by zero or more entries. An entry associates a keyname with a value.

The general format is:

[section]
keyname=value

Comments can also be included in the file by prefacing the comment with a semicolon (;)

This action edits an .INI file on the destination computer. When a WiseScript is called by a Windows Installer installation, you also can edit an .INI file on the Features or Components tabs of Setup Editor in Windows Installer Editor.

To complete the dialog following information is required:

• File: Enter the .INI file path, or select a path from the list and edit it.
• INI File Contents: Enter changes to make in the .INI file.

Changes are interpreted as follows:

To add to a section, type the section name in brackets, then type new lines for that section. If the .INI file already contains a name-value pair that you type, the existing line is replaced by the new one. Example:

[SECTIONNAME]
Name=value 

To delete a section and its contents, type a section name with no lines after it. Example:

[SECTIONNAME]

To delete a name-value pair, type the name with an equals sign followed by nothing. Example:

Name= 

Comments (lines starting with ;) are not supported.
