Question

I want to read a text file that has 3 lines of data one line contains “Server = …” The next line is “Username = .. ” and the last line is “Password = … ” So I want to read this file and put each line into a separate label.. (label1,label2,label3)

OFDSet is my openfiledialog

All in Visual Basic..

Some one help?

Here is the code I tried but I get an error:

Dim oReader As StreamReader

        If OFDSet.ShowDialog = Windows.Forms.DialogResult.OK Then
            oReader = New StreamReader(OFDSet.FileName, True)
            ServLabel.Text = oReader.ReadLine(1)
            UserLabel.Text = oReader.ReadLine(2)
            PassLabel.Text = oReader.ReadLine(3)

        End If

Answer 1

A simpler solution is through the File.ReadAllLines method that gives back an array of strings with just one call.

If OFDSet.ShowDialog = Windows.Forms.DialogResult.OK Then
    Dim lines = File.ReadAllLines(OFDSet.FileName)
    ServLabel.Text = lines(0)
    UserLabel.Text = lines(1)
    PassLabel.Text = lines(2)
End If

See the MSDN reference here

(File class needs an imports for System.IO)

Also if your first line is something like this

Server=MyServerPC

and you want only the part MyServerPC in the ServLabel you need to split the input at the = sign

ServLabel.Text = lines(0).Split("="c)(1)

Of course this is just an example. More robust error handling is needed. You should check if you have at least 3 lines and if each line is correctly separated by the = sign.
