The GetINIValue method returns a value from an INI file. This method, along with SetINIValue, is useful if you need to store a custom value in an INI file and retrieve it for any purpose.

Syntax

GetINIValue(INIFile as String, Section as String, 
    Entry as String [, DefaultValue as String]) as String

Parameters
INIFile
The fully-qualified path to the INI file. Pass an empty string for this parameter to use Data.ini in the Data subdirectory.

Section
The section in the INI file where the value can be found.

Entry
The name of the entry to return the value for.

DefaultValue
The value to return if the specified entry isn't found. Optional; if it isn't specified and the entry doesn't exist, an empty string is returned.

Return Value
The value in the INI file if it was found or a blank string (or the value of DefaultValue if it's specified) if not.

Example
Here's an example that retrieves the location for the AR tables from the AR Location entry in the [Custom Settings] section of the SFQUERY.INI file for the project. If the entry is blank (such as when this code is executed for the first time), the user is prompted for the value and it's stored in the INI file. This code goes into the DataEngine.GetCustomMetaData script.

Visual FoxPro

local lcINIFile, lcLocation, lnI, loTable as Table
lcINIFile  = toApplication.ProjectDirectory + 'SFQUERY.INI'
lcLocation = toApplication.GetINIValue(lcINIFile, ;
  'Custom Settings', 'AR Location')
if empty(lcLocation)
  lcLocation = toApplication.PromptUserForValue('Location of AR Tables')
  toApplication.SetINIValue(lcINIFile, ;
    'Custom Settings', 'AR Location', lcLocation)
endif
if not empty(lcLocation)
  for lnI = 1 to toApplication.DataEngine.Tables.Count
    loTable = toApplication.DataEngine.Tables.Item(lnI)
    do case
      case left(loTable.Alias, 2) <> 'AR'
