[VB.Net] Run the file with the path available in the .ini file

For VB.NET, the following Module can be used:

Module modINI
    Private Declare Unicode Function WritePrivateProfileString Lib "kernel32" _
    Alias "WritePrivateProfileStringW" (ByVal lpApplicationName As String, _
    ByVal lpKeyName As String, ByVal lpString As String, _
    ByVal lpFileName As String) As Int32
 
    Private Declare Unicode Function GetPrivateProfileString Lib "kernel32" _
    Alias "GetPrivateProfileStringW" (ByVal lpApplicationName As String, _
    ByVal lpKeyName As String, ByVal lpDefault As String, _
    ByVal lpReturnedString As String, ByVal nSize As Int32, _
    ByVal lpFileName As String) As Int32
 
    Public Sub writeIni(ByVal iniFileName As String, ByVal Section As String, ByVal ParamName As String, ByVal ParamVal As String)
        Dim Result As Integer = WritePrivateProfileString(Section, ParamName, ParamVal, iniFileName)
    End Sub
 
    Public Function ReadIni(ByVal IniFileName As String, ByVal Section As String, ByVal ParamName As String, ByVal ParamDefault As String) As String
        Dim ParamVal As String = Space$(1024)
        Dim LenParamVal As Long = GetPrivateProfileString(Section, ParamName, ParamDefault, ParamVal, Len(ParamVal), IniFileName)
        ReadIni = Left$(ParamVal, LenParamVal)
    End Function
End Module

Or one more way on VB.NET

  Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
        Dim x() As String
        FileOpen(1, Application.StartupPath & "\file.ini", OpenMode.Input)
        Do Until EOF(1)
            x = Split(LineInput(1), "=")
            If UBound(x) > 0 Then
                If Dir(x(1).Trim) <> "" Then
                    System.Diagnostics.Process.Start("Notepad", x(1).Trim)
                End If
            End If
        Loop
        FileClose(1)
    End Sub

Good Luck.
