Hey!
I have a program that searches for a word in a .txt file. When it finds the word I want to print the following 5 lines under that word. So for example:
I search for "juice", and my label grabs this out of the textfile:
juice
apple
grape
orange
milk
Is there anyway to this in VB.NET?
Jump to PostHi,
Sure read through the file, for each line use the instr function to see if the word exists in that line.

But once you've found the target line, then put a second loop in your code to read in the next five.Dim sr As New System.IO.StreamReader("MyFile") Dim i As Integer Dim Line As String While sr.EndOfStream = False Line = sr.ReadLine If InStr(Line, "Juice") <> 0 …
Hi,

I think you misunderstood. I know how to find the one line, but I need to somehow print the following 5 lines after the line that word is in. That's where my problem is.
Actually I explained it bad.
Let me try again:
I have a code that searches for a word, it finds that word and views a bit of info on the same line as that word. What I need is to also be able to view the next 5 lines as well.

Dim sr As New System.IO.StreamReader("MyFile")
Dim i As Integer
Dim Line As String
While sr.EndOfStream = False
Line = sr.ReadLine
If InStr(Line, "Juice") <> 0 Then
'do what ever with the line
For i = 0 To 4
Line = sr.ReadLine
'print
Next
End If
End WhileThank you!
