[mhb-ksa]

Hi
I have a problem with vb.net

I want write a code to search for line in text file and removed just the line

For example

In form, I have Textbox, in the textbox I was wrote a sentence "Hi, you will remove this line". And I have a button, I want when I click in this button I want removed this line from the text file "notepad"

For example in text file

If you search the forums then this question has been asked and answered before. In summary you would need to read each line from the old file into a new file and just dont write out the lines you wish to remove.
You would then replace the old file with the new one.
