ASP.Net Count number of lines in a text box

Hi

I have a text box which displays the results of a ping.  I only want to display the last 10 results in the textbox though.

How can I count the number of lines in the text box and if there is more than 9 delete the top line using VB.

Many thanks

The ping lines should have a line termination/new line character which you should be able to use along with the String.Substring and String.IndexOf methods. It would look something like:

<textbox value>.substring(<textbox value>.indexOf(Environment.NewLine)+2)

Open in new window


The +2 will "move" the cursor past the two characters that make up the NewLine/Line Feed characters.
