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 :)

View 16 RepliesWhat 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?

View 5 Replieshow 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.

How can I find out the value of the current item in the array?
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.
