calls procedures

hi,

i have mixed a piece of code i found with a simple variable code i made:

Code:

---

Imports System.Runtime.InteropServices
Module inimod
    Public Class IniFile
        ' API functions
        <DllImport("kernel32.dll")> _
        Private Shared Function GetPrivateProfileString(ByVal lpApplicationName As String, _
          ByVal lpKeyName As String, ByVal lpDefault As String, _
          ByVal lpReturnedString As System.Text.StringBuilder, _
          ByVal nSize As Integer, ByVal lpFileName As String) _
          As Integer
        End Function

        <DllImport("kernel32.dll")> _
        Private Shared Function WritePrivateProfileString(ByVal lpApplicationName As String, _
          ByVal lpKeyName As String, ByVal lpString As String, _
          ByVal lpFileName As String) As Integer
        End Function


        Private Declare Ansi Function FlushPrivateProfileString Lib "kernel32.dll" Alias "WritePrivateProfileStringA" (ByVal lpApplicationName As Integer, ByVal lpKeyName As Integer, ByVal lpString As Integer, ByVal lpFileName As String) As Integer

        Private _filename As String


        ' Constructor, accepting a filename
        Public Sub New(ByVal Filename As String)
            _filename = Filename
        End Sub

        ' Read-only filename property
        ReadOnly Property FileName() As String
            Get
                Return _filename
            End Get
        End Property

        Public Function GetString(ByVal Section As String, _
          ByVal Key As String, ByVal [Default] As String) As String
            ' Returns a string from your INI file
            Dim intCharCount As Integer
            Dim objResult As New System.Text.StringBuilder(256)
            intCharCount = GetPrivateProfileString(Section, Key, [Default], objResult, objResult.Capacity, _filename)
            If intCharCount > 0 Then
                GetString = Left(objResult.ToString, intCharCount)
            Else
                GetString = ""
            End If
        End Function



        Public Sub WriteString(ByVal Section As String, _
          ByVal Key As String, ByVal Value As String)
            ' Writes a string to your INI file
            WritePrivateProfileString(Section, Key, Value, _filename)
            Dim chan1 As String
            Dim chan2 As String
            Dim chan3 As String
            Dim chan4 As String
            Dim chan5 As String
            Dim chan6 As String
            Dim chan7 As String
            Dim chan8 As String
            Dim chan9 As String
            Dim chan10 As String
            Dim r
            chan1 = main.memfreq1.Text
            chan2 = main.memfreq2.Text
            chan3 = main.memfreq3.Text
            chan4 = main.memfreq4.Text
            chan5 = main.memfreq5.Text
            chan6 = main.memfreq6.Text
            chan7 = main.memfreq7.Text
            chan8 = main.memfreq8.Text
            chan9 = main.memfreq9.Text
            chan10 = main.memfreq10.Text
            r = WritePrivateProfileString("RadioLinks", "1", chan1, Application.ExecutablePath & "\test\test.ini")
        End Sub
    End Class

End Module

and i want to call this part with a button click at my main form:

Code:

---

        Public Sub WriteString(ByVal Section As String, _
          ByVal Key As String, ByVal Value As String)
            ' Writes a string to your INI file
            WritePrivateProfileString(Section, Key, Value, _filename)
            Dim chan1 As String
            Dim chan2 As String
            Dim chan3 As String
            Dim chan4 As String
            Dim chan5 As String
            Dim chan6 As String
            Dim chan7 As String
            Dim chan8 As String
            Dim chan9 As String
            Dim chan10 As String
            Dim r
            chan1 = main.memfreq1.Text
            chan2 = main.memfreq2.Text
            chan3 = main.memfreq3.Text
            chan4 = main.memfreq4.Text
            chan5 = main.memfreq5.Text
            chan6 = main.memfreq6.Text
            chan7 = main.memfreq7.Text
            chan8 = main.memfreq8.Text
            chan9 = main.memfreq9.Text
            chan10 = main.memfreq10.Text
            r = WritePrivateProfileString("RadioLinks", "1", chan1, Application.ExecutablePath & "\test\test.ini")
        End Sub

---

but the call procedure and is not working. even when i set:

Code:

---

         
Sub writeproperties()
 Dim chan1 As String
            Dim chan2 As String
            Dim chan3 As String
            Dim chan4 As String
            Dim chan5 As String
            Dim chan6 As String
            Dim chan7 As String
            Dim chan8 As String
            Dim chan9 As String
            Dim chan10 As String
            Dim r
            chan1 = main.memfreq1.Text
            chan2 = main.memfreq2.Text
            chan3 = main.memfreq3.Text
            chan4 = main.memfreq4.Text
            chan5 = main.memfreq5.Text
            chan6 = main.memfreq6.Text
            chan7 = main.memfreq7.Text
            chan8 = main.memfreq8.Text
            chan9 = main.memfreq9.Text
            chan10 = main.memfreq10.Text
            r = WritePrivateProfileString("RadioLinks", "1", chan1, Application.ExecutablePath & "\test\test.ini")
        End Sub

---

.

i made some stuff on vb6 a few years and im not a regular coder, i have a book for api functions but is regarding vb6 and vb8 seems diferent...

How can i write on my ini through the click of the main form button calling the function in the module?

Thanks:

Try this class

To write to the ini file

Code:

---

IniFile.WriteKey("RadioLinks", "1", chan1, Application.ExecutablePath & "\test\test.ini")

Thanks ..it worked perfectly..i can now set the radio station links to my humble app... :)

Thanks again:
