These numbers should display one after the other rapidly and should stop run whenever another command button is clicked hence the lucky is seen on a label or textboxes, is just like a raffle.

I am using VB.net 2010 and SQL client server.I have to make a Weekly Report Manager that stores an Trainees' weekly activity, which would probably be in a paragraph form.I think I can use Textbox (multilined) or Richtextbox for this.But When I tried to store and read the stored data it is not multilined.
Example:
INPUT in textbox/richtextbox: I am a good trainee inserted it in database as textbox.text or richtextbox.text and the result will be:
I ama goodtrainee
So if I retrieve the data it displays a single lined text.How can I do it properly?

a user copies multiple lines of text (say, from an email) into the clipboard. Based on my observations, when one tries to paste the text into a single-line textbox, only the first line is actually pasted in. (I am aware that the "obvious" solution would be to set the Multiline property to True, but there are reasons I am looking to avoid this and to put multi-line data into a single line.)
In the TextChanged event handler, I wrote code that parses the clipboard data to successfully convert it to a single-line, comma-delimited format.

The following code selects a line ina richtextbox. It works OK expect from one problem:
When a line is biger than the size of the richtextbox, it wraps it. This create a big problem as I can not select the last line of the richtextbox (when a line is wrapped it becomes two lines). When I set wordwrap to off it works just fine
