what is the code for searching for and removing a blank line in a multi-line text box? im using VB Express '08 and can not figure it out.

my problem is im loading a sample.text file and using txtFile.AppendText(ControlChars.NewLine & activetext & ",") to add new text from user input and get a blank line that causes problems when converting the text into my array. it looks like this:

please HELP! i am out of ideas and everything else is working except this. all i need is that blank line to go away. lol

any ideas or suggestions would be most appreciated.
can post more of my code if needed.

to remove the blank lines on reading it ou could do:

Dim tmp() As String = My.Computer.FileSystem.ReadAllText("C:\test.txt").Split(vbNewLine)
        For Each newStr As String In tmp
            If newStr.Length > 2 Then TextBox1.AppendText(newStr & vbNewLine)

if you want to update the textbox you could do:

Dim tmp() As String = TextBox1.Text.Split(CChar(vbNewLine))
        For Each line As String In tmp
            If line.Length > 1 Then
                TextBox1.AppendText(line & vbNewLine)
            End If

i've posted both possibility coz it wasnt really clear to me what exactlly u wanted (at what time) ... guess need more coffee

You can try this (not tested deeply)

Dim SearchIn = Me.TextBox1.Text
Dim sb As StringBuilder = New StringBuilder(SearchIn)
Me.TextBox1.Text = sb.Replace(vbCrLf + vbCrLf, vbCrLf).ToString
