Hello All,

I am getting trouble in sentence selection in vb.net.
What I want to is that, I put the text into the main text area and when I click on next button ">>" it will select the next sentence and so on.... Same for the previous button it will select the previous sentence. Please consider the DOT (.) as the sentence stopper.

Please help me ASAP.

Thanks to All.

Regards
Kapil

Rather than provide code I am going to make a suggestion. It is better to learn by doing than by copying.

Use the Find() and FindNext() to locate the periods, Then select the text

Here are the RichTextBox Methods. Lots of cool stuff that you can use.

Some Sample code, just in case.
