but these links are all about reading files...but i want to delete the text in textbox...so what to do??

Maciej Los 10-Apr-13 2:14am

Take a look at this line: "To replace text..."

'WinForms:
sText = Me.TextBox1.Text
sText = Replace(sText, "find", "replacewith")

Is it so hard to read answer to the end?

For another useful links, see updated answer.

thank u for your support but it doesn't work :(

Maciej Los 10-Apr-13 2:41am

What "doesn't work"? If you want to get solution, please, provide more details. "doesn't work" is not informative at all.

Do not re-post your previous code. Please, show me what have you done so far. I think you did not read any linked article at all.

Lines(number of lines you want to replace)=...

Wow. You REALLY need to pick up a beginners book on VB.NET and work through it. It's obvious that you don't understand what this code is doing at all and that you need to replace the phrase "number of lines you want to replace" with actual code.
