opening a file

Well I am used to VB6 or something either that or i forgot how to program in Visual Basic. I have a modual named mdlDataInput and in there I have a public function named Main_Config(). Now in VB 6 I remember I could just go

Code:

---

open app.path + "\Main Config.ini" for input as #1

---

and it would open the file just fine. Now it says some crap about a namespace and what not so i added this and it still does't work, it also gives me some problems about the app command. Can someone help me out.

Code:

---

Module mdlDataInput
    Public Function Main_Config()
        Dim open As Microsoft.VisualBasic
        ' OPEN THE MAIN_CONFIG.INI FOR INPUT
        open app.path + "\Main Config.ini" for input as #1

    End Function
End Module

---

You should try searching in the .NET help for 'Open File' or 'Visual Basic 6 differences' and it will give you an example. As for the App.path there is no App object in .NET use: Application.StartUpPath instead.

Although I would say ditch the INI file and use XML instead, you can load it into a dataset and make things much easier.

Here is a sample of how to read a file just in case (Although the xml way is better):

VB Code:

Dim fs As System.IO.FileStream = New System.IO.FileStream(System.IO.Path.Combine(Application.StartupPath, "Main Config.ini"), IO.FileMode.OpenOrCreate)
        Dim sr As New System.IO.StreamReader(fs)
        Dim contents As String = sr.ReadToEnd
        sr.Close()
        fs.Close()
        sr = Nothing
        fs = Nothing

You could also shorten this if you put some Imports at the very top outside of the class:

VB Code:

'At the top
Imports System.IO 'works kind of like a giant With..End WIth
 
        Dim fs As FileStream = New FileStream(Path.Combine(Application.StartupPath, "Main Config.ini"), FileMode.OpenOrCreate)'Opens file
        Dim sr As New StreamReader(fs)'here is an object to read it
        Dim contents As String = sr.ReadToEnd'reads the whole file to the string
        sr.Close()' clean up
        fs.Close()
        sr = Nothing
        fs = Nothing
