If statement [RESOLVED]

[bat711]

I have a loop that goes through a logfile line by line and does certain events if certain strings are in that line. My question is how do I get it to skip to the next line if it contains a certain string? I'm trying to use If statements like below, I'm just not sure how to do it.

Do While Not EOF(1)
    Line Input #1, strReadLine
 
    If InStr(blah blah) Then
        'Do some stuff
    End If
 
    If InStr(other blah blah) Then
        'Go to next Line
    End If
Loop

Just allow it to go to the loop which will move on to the next line. If I misunderstood you, please post a better explanation

Actually now that I look at my example it was a bad one, sorry...

It's nested actually, would look more like this:

Do While Not EOF(1)
    Line Input #1, strReadLine
 
    If InStr(1, strReadLine, "S ") Then
        If InStr(1, strReadLine, "grep") Then
            'Go to next Line
        End If
 
        If InStr(1, strReadLine, "/") Then
            'Do some events
        End If
    End If
Loop

So how do I get it out of that nested If?

If I understand you correctly, you can just use an ELSE

Do While Not EOF(1)
    Line Input #1, strReadLine
 
    If InStr(1, strReadLine, "S ") Then
        If InStr(1, strReadLine, "grep") Then
            'Go to next Line
        else
          If InStr(1, strReadLine, "/") Then
              'Do some events
          End If
        endif
    End If
Loop

Why not just do

Do While Not EOF(1)
    Line Input #1, strReadLine
 
    If InStr(1, strReadLine, "S ") Then
        If InStr(1, strReadLine, "grep") Then
            'Go to next Line
             Loop
        End If
 
        If InStr(1, strReadLine, "/") Then
            'Do some events
        End If
    End If
Loop

I'm not sure if I get you either, but if I do, something like this would work:

Do While Not EOF(1)
    Line Input #1, strReadLine
    If InStr(1, strReadLine, "S ") Then
        If InStr(1, strReadLine, "/") Then
            'Do some events
        ElseIf InStr(1, strReadLine, "grep") <= 0 Then
            Exit Do
            'So unless there's "grep", it won't continue.
        End If
    End If
Loop

Ok, using the else statement worked, thanks. Hack, I'm not sure that would work for my case because if "grep" is in the line I don't want to do anything with it or than go to the next line and it shouldn't be in the file more than once.

Thanks guys.

Loop

Or keeping your structure the same...

Do While Not EOF(1)
    Line Input #1, strReadLine
 
    If InStr(blah blah) Then
        'Do some stuff
        GoTo LoopEnd
    End If
 
    If InStr(other blah blah) Then
        'Go to next Line
        GoTo LoopEnd
    End If
LoopEnd:
Loop

P.S. well goto statements are not very good to be used often...

Why not just do

Do While Not EOF(1)
    Line Input #1, strReadLine
 
    If InStr(1, strReadLine, "S ") Then
        If InStr(1, strReadLine, "grep") Then
            'Go to next Line
             Loop
        End If
 
        If InStr(1, strReadLine, "/") Then
            'Do some events
        End If
    End If
Loop

I think that will only work in C. Are you telling that this code compiles? (I've not tested).

[bat711]

Yes that is what I was trying to figure out a sort of Go to statement. I Haven't used that since regular BASIC I think.

[Mc Brain]

I believe the easier way is:

Do While Not EOF(1)
    Line Input #1, strReadLine
 
    If InStr(1, strReadLine, "S ") > 0 And InStr(1, strReadLine, "grep") = 0 Then
        If InStr(1, strReadLine, "/") Then
            'Do some events
        End If
    End If
Loop
