simple help i think..

well i'm in the process of creating a simple guess the number game but the problem i'm having is writing to a file i don't know the code :$

i'v got 2 cases where i need to use this, for a log in where the user can create there own username and password and for the highscores so the user can enter there name and score.

if anyone can help that will be great and if you want me to post the code i currently have for both those i can do

thanks

ow iv got it so the information can be retrieved from the file so that it is displayed and i can log in but not that i can created my own password and username without actually going the the file and adding the information in there, if that helps anymore :$

 

youre wanting to read and write a textfile?

open a file

Code:

If OpenFileDialog1.ShowDialog = Windows.Forms.DialogResult.OK Then
            Dim sr As IO.StreamReader = New IO.StreamReader(OpenFileDialog1.FileName)
            While sr.Peek >= 0 ' or sr.endofstream=false
               ListView1.Items.Add(sr.ReadLine) 'will add the txt to a listview. 
'textbox1.text = split(split(sr.readline, "[User:")(1), "]") ' assuming you have "[User:BOB]" in a txt, it will load it..
'note the split can be used in listview if needed 'ListView1.Items.Add(split(split(sr.readline, "[User:")(1), "]") ) 
            End While
  sr.Close()
        End If      

save

Code:

If SaveFileDialog1.ShowDialog = Windows.Forms.DialogResult.OK Then
            Dim sw As IO.StreamWriter = New IO.StreamWriter(SaveFileDialog1.FileName)
            For i As Integer = 0 To ListView1.Items.Count - 1
                If i = ListView1.Items.Count - 1 Then
                    sw.Write(ListView1.Items(i).Text)
'could add it to save username, etc ' sw.Write("[User:" & ListView1.Items(i).Text & "]")
                Else
                    sw.WriteLine(ListView1.Items(i).Text)
'here too..' sw.WriteLine("[User:" & ListView1.Items(i).Text & "]")
                End If
            Next
            sw.Close()
        End If

or save from textbox..

Code:

    If SaveFileDialog1.ShowDialog = Windows.Forms.DialogResult.OK Then
            Dim sw As IO.StreamWriter = New IO.StreamWriter(SaveFileDialog1.FileName)
            For i As Integer = 0 To ListView1.Items.Count - 1
                If i = ListView1.Items.Count - 1 Then
                    sw.Write(textbox1.Text)
                    'could add it to save username, etc ' sw.Write("[User:" & textbox1.Text  & "]")
                Else
                    sw.WriteLine(textbox1.Text)
                    'here too..' sw.WriteLine("[User:" & textbox1.Text & "]")
                End If
            Next
            sw.Close()
        End If
    End Sub

i think that covers the examples i was trying to give..and obviously if your not using openfiledialog or savefiledialog, just remove the following:

Code:

 If SaveFileDialog1.ShowDialog = Windows.Forms.DialogResult.OK Then
end if
If OpenFileDialog1.ShowDialog = Windows.Forms.DialogResult.OK Then
end if
