writing the following code to use it
Dim objIniFile As New IniFile("c:\data.ini")
objIniFile.WriteString("Settings", "ClockTime", "12:59")
Dim strData As String = _
objIniFile.GetString("Settings", "ClockTime", "(none)")
To run an application from .NET using the following code
Process.Start("NotePad.exe")
