Parsing Text File doesn't pickup all If statements

[finked1973]

Hi All

I have a piece of code in my application that is giving me a funny result. I am reading a text file and based on it's first word on the line I have a bunch of IF statements that then assign the value to a variable.
The problem is that not all the if statements are being met, well they are but that's what's weird.
Here's my code and I'll explain

        If File.Exists(varIni) Then
            Dim readFile As System.IO.TextReader = New StreamReader(varIni)
            Dim line As String
            While readFile.Peek > -1
                line = readFile.ReadLine()
                If line.Substring(0, 9) = "CompName=" Then
                    varCompName = line.Substring(9, line.Length - 9)
                    TextBox5.Text = varCompName
                End If
                If line.Substring(0, 12) = "PhoneNumber=" Then
                    varPhoneNum = line.Substring(12, line.Length - 12)
                    TextBox6.Text = varPhoneNum
                End If
                If line.Substring(0, 11) = "WebAddress=" Then
                    varWebAdd = line.Substring(11, line.Length - 11)
                    TextBox7.Text = varWebAdd
                End If

                'If line.Substring(0, 13) = "EmailAddress=" Then
                '    varMailAdd = line.Substring(13, line.Length - 13)
                '    TextBox8.Text = varMailAdd
                'End If

                If line.Substring(0, 11) = "EmailLogin=" Then
                    varMailLog = line.Substring(11, line.Length - 11)
                    TextBox9.Text = varMailLog
                End If
                If line.Substring(0, 10) = "EmailPass=" Then
                    varMailPass = line.Substring(10, line.Length - 10)
                    TextBox10.Text = varMailPass
                End If
                If line.Substring(0, 11) = "HourlyRate=" Then
                    varHourly = line.Substring(11, line.Length - 11)
                    TextBox11.Text = varHourly
                End If
                If line.Substring(0, 9) = "MealRate=" Then
                    varMeal = line.Substring(9, line.Length - 9)
                    TextBox12.Text = varMeal
                End If
            End While
            readFile.Close()
            readFile = Nothing
        Else
            MessageBox.Show("You will need to configure your application, please go to the Configuration tab and fill in the details for your business", "xlcr IT Solutions", MessageBoxButtons.OK, MessageBoxIcon.Exclamation)
        End If

You will notice that half way down the IF statements there is one block that is commented out, if I leave this commented out all values are assigned, if I uncomment the block the last two variables are not assigned.

Can someone shed any light as to why this is happening ?

Thanks in advance

Don't worry about this, I managed to do a workaround, I took out the = signs in the if statement eg

If line.Substring( 0, 10) = "EmailLogin " Then
varMailLog = line.Substring( 11, line.Length - 11)
TextBox9.Text = varMailLog
End If

God knows why it wasn't working but I've spent too long on it

Cheers

Finally understand why

If anyone else has this problem, here is my understaning of it.

When you substring a line in a reader function and run that through a block of if comparisons if the substring value is for example 12 and it hits a line in the fil of say 8, that line of 8 is too short for the comparison of 12. This causes the code to error.
To sort any comparison block substrings should be the same size for it to work correctly.
