basic language question

[zeroGrav]

In a do loop how do I skip to the next iteration?

 

In java, there's the 'continue' keyword...

 

If there's no 'continue' for a do loop what about while loops or for loops?

 

My book really doesn't tell me anything related to this...

 

Thanks.

I suppose the best way would be to use a Boolean.

 

Do While MyCondition = True
 Dim continue As Boolean

 'In C#, this would look like [b]if (This == "That") continue;[/b]
 If This = "That" Then continue = True

 'This part skips all the code after the continue line, if necessary
 If Not continue Then 'You did not choose to go to the next iteration
   'Nested continues should work as well.
   'C#: if (Equation = (4+3/5)^4) continue;
   If Equation = (4+3/5)^4 Then continue = True
   If Not continue Then
     'Once again, you didn't choose to go to the next iteration
   End If
 End If
Loop

I don't know if this is a total reproduction of the behaviour of

continue, nor have I tested it, but it should work. :-\ Best you can

do is give it a shot.

That or use a goto statement to jump to the end, just before the loop statement. And before you say it, what do you think a continue statement does? :)

[Volte]

So theoretically, my way is better than continue. ;) ;)

[divil]

Why, you think yours doesn't use one? ;)

[Volte]

Heh, this is about coding standards, not the way it eventually turns

out after it's compiled. :p

fact is, guys, that vb .NET _lacks_ a continue statement. That's a shame ,though, because it vb.net is a great language overall. Some may say nothing is perfect...

I can't remember thinking that I needed a continue statement since my quickbasic days. I guess you just to not using them. I don't think any MS BASIC language has ever had one. They're not very structured anyway :)

They are useful in some situations, but I haven't had the need for one in years. When I did (in VB6), I used an "If...Then" as VolteFace showed in his first example.

 

You're right, it's a shame they didn't include something seemingly so simple in VB.NET. But then, C# and VB.NET are different languages...
