Auto close carriage returns/space between paragraghs - VB.NET 2010

HI Experts,

I have a laborious task in work of pasting text into notepad and manually closing-up any extra carriage-returns in the format... I'd like advice on how to paste into a Text Box (win form) and it auto closes spaces...

From: e.g. (currently)
xxxxxx

xxxx

xxxxxxxxx

TO: e.g. (new solution)
xxxxxx
xxxx
xxxxxxxxx

Try

textbox1.text = textbox1.text.replace(vbcrlf & vbcrlf, vbcrlf)

Hi CC,

Your code almost works... it leaves 1 space line between cetain text... please see my pic... i've numbered the CR lines.

It is possible to complete close CR?

Thanks,
Roberto

You can try using Trim

Dim txt As String
For each line in textbox1.Lines
If string.IsNullOrEmpty(line) = False Then
txt &= line.trim() & vbcrlf
End If
Next
Textbox1.text = txt.Trim().Trim(vbcrlf).Trim()

this had no effect - can you check my code - is it something i've done?

Dim txt As String
    
    Private Sub TextBox1_TextChanged(ByVal sender As System.Object, ByVal e As System.EventArgs)

        For Each line In TextBox1.Lines
            If String.IsNullOrEmpty(line) = False Then
                txt &= line.Trim() & vbCrLf
            End If
        Next
        TextBox1.Text = txt.Trim().Trim(vbCrLf).Trim()

    End Sub

Open in new window

You are using the wrong event by the way. This will cause an infinite loop. What happens if you use a button or if you use two textboxes?

Do you mean <TextBox1_TextChanged> this bit?

Nasir Razzaq

Yes

I can't see any alternate in Declarations... do you know which one will work please CC?

Nasir Razzaq

What I meant was that you are changing the text of textbox in its text_changed event which means the event will fire again, text will be changed again, event will fire again .....

Use one textbox to put text in and another to put modified text in.
