Hi!
sorry for a dumb question. I have a textbox where multiline=true and I want
to set the scrolbar from none to vertical when the textbox have more then
f.ex. 5 lines,
or reverse.
How can I count the amount of lines in a textbox?
Best regards

Hi Hans,
One approach would simply be to split the textbox text at the newline
character and then count how many strings you get. For example:
string [] lines = this.textBox1.T ext.Split('\n') ;
MessageBox.Show (lines.Length.T oString());
If you care whether or not a line is empty, you'll actually need to
look at the content of lines[].
Hope that helps.

Hi Jon
Thank you for your help.
After som brainstorm this worked for me.
if (this.textbox1. Line.Length 5)
this.textbox1.S crolbar = Scrolbar.Vertic al
else
this.textbox1.S crobar = Scrolbar.None
Note: this does'nt work if Wordwrap=true and you aren't pressing enter for
new line.
Do you have nay idea for solution.
Best regards

If you have set WordWrap to true, chances are you will have no newline
characters at all...
except that some lines _WRAP_ also right?

Hi!
Thank you all for your replies. I've found out that a RichTextBox is in my

You could always set Wordwrap= false :)
Othen than that I have no idea how to solve this. Why don't you post (or
search) in a javascript forum.

Which would be faster for counting lines in a StreamReader:
(a) iterate through a file using .ReadLine() and adding to a counter, i++
(b) doing a .ReadToEnd() and then using an IndexOf() method to count the
occurances of \r\n
(c) doing a .ReadToEnd() and using a RegEx to count the number of occurances
of \r\n

I've been trying to do line/character counts on documents that are

Ok. I have a windows form with a textbox for displaying certain messages.
Multiline=true and wordwrap=true. I want to know the amount of the lines
currently showing. That should not be any rocket-science, eh?
Textbox.lines.length() only returns the amount of lines ending with a 'hard'
CrLF, not the lines with a 'soft' CrLf done by the wordwrapping option. Why,
I don't know. I don't want to know how much lines are ending with 'hard'
CrLf....

Thanks for the responses in a former thread about getting the count of lines
in a multiline textbox with wordwrap.
After some tinkering, I found the solution (based on a VB6 solution, had to
modify a bit for VB.NET):
<DllImport("user32.dll")> Private Shared Function SendMessage(ByVal hWnd As
IntPtr, ByVal wMsg As Int32, ByVal wParam As Int32, ByVal lParam As Int32)
As Int32
End Function

I have a multi-line text box in a compact framework c# application. I
need a method to calculate the excact number of lines of the textbox

Any ideas?

Hello folks,
I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
This is as boiled down as I can make it.
