I was trying back yesterday to count the visible lines in a textbox, which is multiline, and found this article: [URL] but... it didn't work... The code worked fine, but sometimes it returned like, 5 or 4, when I counted the visible lines, and there was 2.. If you know what's wrong/have any answer for this it would be nice :)

What I am trying to do is remove lines of a multiline TextBox based on certain criteria, such as the number of characters or words. For example, if I paste a list of phrases into the TextBox, I want to remove all phrases that contain more than 25 characters. Once the phrases are removed, I then want to remove the empty lines that are left behind, but I have commented out the ".Replace(vbCrLf & vbCrLf, vbCrLf)" for the sake of making the results easier to follow (see screenshot from Excel below, which includes a blank cell wherever a phrase has been removed).
Here is my
Private Sub Button1_Click(ByVal sender As Object, ByVal e As EventArgs) Handles Button1.Click
Dim lines() As String = TextBox1.Text.Split(vbCrLf)
[Code]....
Why is it not "blanking" the entire line in ALL cases where the line contains more than 25 characters?

How can I pull individual lines out of a multiline textbox when wordwrap=true?
For example I have a long string in a textbox and it wordwraps to create 3 seperate lines. How can I get the text of the 2nd line? The control thinks that there is only 1 line since it wordwrapped and there are no CRLFs in the string.

how to count the lines in textbox1.text (with multiplelines). I don't need to count each character. I only need to count each line from top to bottom in textbox1.text (multiplelines) and I will use Label1 to display the numbers.
example:
1-pauljaones
2-tommyperrry
3-marktoms
4-Jonessmith
5-paulwhite
Obviously this is 5 lines and that's what I need to count.

I'm trying to iterate through each line of a multiline textbox. Something like:
For Each line In Me.txtBox1.Lines
Response.Write line.Text
Next
Is there any neat way to do this, or will I need to write a character-by-character parser and look for carriage returns?

I have a multiline textbox that while a file is read in some data is echo'ed out onto the textbox. Is is possible to programatically scroll the object down to the bottom? Changing everything over to a combobox and then changing the selected index would essentially do what I want, but the user needs to select/copy a bunch of lines.

I'm trying to make a textbox at runtime, Dim t as Control
t = New Textbox
t.Multiline = True
t.Size = New Size(300,120)
Form1.Controls.Add(t)
I found out that you can only size a textbox when Multiline is set true. And that's the problem. When I use t.Mutiline = true I get the error " 'multiline' is not a member of 'system.windows.forms.control' "
I've searched the internet for hours without result.

I have spent the last hours trying to make an easy fix for this. Setting it to enabled=false is no good in this case. What I was looking for is a way to prevent the user to place the cursor in a multiline textbox. This is a read only textbox, and the user can't type anything in it, but for some reason he can still place the cursor in it, that is what I try to prevent.

I'm using a couple of multi-line textboxes to check output from my program, but it always scrolls back to the top of the box. Is there some way to set it so that it's always scrolled down to the end? Scrolling manually doesn't help because it just keeps resetting to the top.

I have a multiline textbox with text that i want to add to a listbox. Each line in the textbox should be a new line in the listbox.
I had a problem when going from listbox to textbox but that was solved with
VB.NET
For Each item As String In EnDeCrypt.ListBox1.Items
EnDeCrypt.TextBox1.AppendText(item & Environment.NewLine)
Next
Is it adaptable to do what i'm trying to do now?
