How to add reference of IniFile.dll on Microsoft Visual Studio

  • From top menu choose Project then Properties
  • Open References tab
  • Click Add... button

Basic usage

At first we might need to imports IniFile library:

Imports GLib.IniFile

Load INI file:

Dim oIniFile As New GLib.IniFile

Dim lLoad As Boolean 

'-- Load TEST.INI file on current EXE directory
lLoad = oIniFile.LoadFile("TEST.INI")

If (lLoad = False) Then
  '-- File not found
End If

'-- Load TEST.INI file on "D:\myapp" directory
lLoad = oIniFile.LoadFile("D:\myapp\SAMPLE.INI")

If (lLoad = False) Then
  '-- File not found
End If

Read two items value:

Dim str1 As String = oIniFile.Items("str1")
Dim str2 As String = oIniFile("str2")

Change two items value:

oIniFile.Items("str1") = "ABC"
oIniFile("str2") = "DEF"

Save INI file:

Dim lSave As Boolean 

'-- Save using the file name passed on LoadFile()
lSave = oIniFile.SaveFile()

If (lSave) Then
  '-- Success
End If

'-- Save to specific directory and file name
lSave = oIniFile.SaveFile("D:\sample\SETTINGS.INI")

If (lSave) Then
  '-- Success
End If
