Rich Text Box Question

[sradel]

I wrote a little app that has the ability to change, add, or delete a line of text in multiple txt files by pulling each one into a rich text box, changing the text line, and then saving the changes back to the file. Every thing works seems to work ok.

The only issue i have is that when i add a new line to the bottome of the rich text box and there are empty lines imported from the text file, then the text will be written after the blank lines.

Is there any way to remove empty lines from a text file or rich text box before i add the line or import the file?

thanks

Show us some code. Why do you load the file into a rich text box?

Thanks, but the code i have works fine. I pull the file into a RTB to enable the user to manually edit it. This made it easy to also pull it in when a line is being Added, Changed, or deleted in batch using a pause so the user can see the files being changed. I have no idea why they wanted this. But all this works just fine. The one thing i do not know how to do is remove empty lines from a rich text box. I just recieved a code snippet from another forum, i will try it and if it works will post it here for others to reference. thanks for your time.

THis is the code that works. thanks for the help.

Dim GoodLines As New List(Of String)
For Each s As String In frmMain.rtbEditor.Lines
If Not s.Trim.Equals(String.Empty) Then
GoodLines.Add(s)
End If
Next
frmMain.rtbEditor.Lines = GoodLines.ToArray

Personally, I woulda just:

myRTB.Text = myRTB.Text.Trim()
