Managing information in initialization files
Functions for accessing
initialization files
PowerBuilder provides several functions you can use to manage
application settings in initialization files.
| Function | Description |
|---|---|
| ProfileInt | Obtains the integer value of a setting in a profile file |
| ProfileString | Obtains the string value of a setting in a profile file |
| SetProfileString | Writes a value in a profile file |
For complete information about these functions,
see the PowerScript Reference
.
For how to use the ProfileString functions
with the registry, see “Functions for accessing
initialization files”.
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:
|
1 |
[Preferences] |
|
1 |
WindowColor=Silver |
|
1 |
BorderColor=Red |
|
1 |
BackColor=Black |
|
1 |
TextColor=White |
Reading values
The following
script retrieves color settings from the APP.INI file:
|
1 |
wincolor = ProfileString("app.ini", "Preferences", "WindowColor", "")<br />brdcolor = ProfileString("app.ini", "Preferences", "BorderColor", "")<br />bckcolor = ProfileString("app.ini", "Preferences", "BackColor", "")<br />txtcolor = ProfileString("app.ini", "Preferences", "TextColor", "") |
Setting values
The following
script stores color settings in the APP.INI file:
|
1 |
SetProfileString("app.ini", "Preferences", "WindowColor", wincolor)<br />SetProfileString("app.ini", "Preferences", "BorderColor", brdcolor)<br />SetProfileString("app.ini", "Preferences", "BackColor", bckcolor)<br />SetProfileString("app.ini", "Preferences", "TextColor", txtcolor) |
