[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 �notepad�, I was wrote this text

{

I am a beginner in English language

Hi, you will remove this line

Help me please to removed

}

 

 

Please I want the code, please help me

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 don't write out the lines you wish to remove.

You would then replace the old file with the new one.

I think he's asking to interface directly into Notepad? If so, that's a bigger topic...
