How do you exit a loop?

[Quintile]

huh? HUH!?

[hellswraith]

exit for

[Joacim Andersson]

or
Exit While
Exit Do

[filburt1]

You can also exit a function or sub with that keyword, so the complete list (according to the VB5 help) is:

Exit Do
Exit For
Exit Function
Exit Property
Exit Sub
Exit While ' they forgot that

No I didn't

[filburt1]

I mean the VB5 help did.

[Harddisk]

Too bad, Exit While no longer works in VB6

[Joacim Andersson]

Well use a Do While loop instead then.

[Harddisk]

Yes, I've always use DO WHILE loop, instead of WHILE WEND loop. Wondering, is there any difference other than the ability to exit loop.

The main difference is of course that you can put the While statement at the end of the loop and by doing that the loop will execute at least once.

Why would they kill the While-Wend loop? It's probably one of the most useful ones in any language.

filburt1, While Wend is still available, except that you are not able to exit/break from the loop halfway running it.

The While ... Wend loop is actually sort of depricated. You can always use a Do While .... Loop iteration instead.
BTW it has changed in VB.Net to While ... End While to be more like any other block statements in VB.

But as pointed out the two loops have different purposes; even in C++ and Java there's:

do
{

} while (condition);

// and

while (condition)
{

}

So do both loops still exist in VB.Net?

Also yahs forgot the

Do Until
and
Loop Until

Example:

Do until a=5
Loop Until a=5

The difference is very small. If you use DO Until then the code will run one last time. If you use loop until it will stop looping immediately.

In VB you can use a Do loop for both cases.

Do While condition
    'this is exactly like a While ... WEnd loop
Loop
'or
Do
     '...
Loop While condition

Both of these still exists in VB.Net. I as I already mentioned the other While loop still exists it just changed from WEnd to While End.

'VB.Net code
While condition
    '...
End While

Do Until is the exact same thing as Do While Not, it's just a preference of how you want to type it.

Best regards
