The format of APP.INI

The examples below manage application information in a profile file called APP.INI. This file keeps track of user preferences that control the appearance of the application. It has a Preferences section that stores four color settings:

[Preferences]
WindowColor=Silver
BorderColor=Red
BackColor=Black
TextColor=White

Reading values

The following script retrieves color settings from the APP.INI file:

wincolor = ProfileString("app.ini", "Preferences", "WindowColor", "")
brdcolor = ProfileString("app.ini", "Preferences", "BorderColor", "")
bckcolor = ProfileString("app.ini", "Preferences", "BackColor", "")
txtcolor = ProfileString("app.ini", "Preferences", "TextColor", "")

Setting values

The following script stores color settings in the APP.INI file:

SetProfileString("app.ini", "Preferences", "WindowColor", wincolor)
SetProfileString("app.ini", "Preferences", "BorderColor", brdcolor)
SetProfileString("app.ini", "Preferences", "BackColor", bckcolor)
SetProfileString("app.ini", "Preferences", "TextColor", txtcolor)
