is there an equivalent key word for C++'s "continue" in VB (.net) in this
context?


CString szLine;
szLine = myReader.ReadLine();
while ( !szLine.IsEmpty() )
{
if ( szLine(0) == '-' )
{
szLine = myReader.ReadLine();
continue; // <-- HERE, so if szLine starts with "-" then
// the rest of this loop is not executed this
time round...
}

szLine = myReader.ReadLine();

//
// rest of the loop code
//

}


thanks!
Daniel.

Herfried,
Are you sure is it in that equivalent not something as exit while loop
But when you say so .................................................
Cor

try useing break to drop out of the loop

In VB .NET?!

Daniel,
The closest you will come to a Continue in VB.NET is to use the Goto
keyword.

Something like:
szLine = myReader.ReadLine()
Do Until szLine Is Nothing
If szLine.Chars(0) = "-"c Then
szLine = myReader.ReadLine()
GoTo continue
End If
szLine = myReader.ReadLine()
If szLine is Nothing Then Exit Do
'
' rest of the loop code
'
continue:
Loop

Personally I would put a single ReadLine after the Continue, avoiding the
third ReadLine. Also I would consider having the 'rest of the loop code' in
the Else block of the If comment block. Or change the If comment to If Not
comment rest of loop code.

Hope this helps
Jay

There's always another way of writing it - how about instead of trying to =
'-', you test not equals to '-'

eg
while(not empty)
{
if(last char != '-')
{
rest of code in here
}
}

reads better too i think

I'm afraid I have to disagree, nested parenthesis (or begin/end's in a VB
case) isn't that pleasing to the eye...

if your reading through the code, seeing a continue near the start signifies
a conditional loop, but seeing two sets of begin/end's can get confusing
when you're looking at something like

function ...()
{
while m_bWhatever
{
if ( my condition is true )
{
... code here ...
}
}
}

the last }'s can get confusing, especially in large multilevel functions.

it's all about preference I guess! ;o)

Thanks for your comment.

Jay,
Sorry, but this is terrible, all the work of Dijkstra (he died last year) is
done with what you wrote (while your examples are normaly so good).
szLine = myReader.ReadLine()
Do Until szLine Is Nothing
If szLine.Chars(0) = "-"c Then
szLine = myReader.ReadLine()
' GoTo continue /// removed
' End If /// removed
Else ' that is all Cor inserted
szLine = myReader.ReadLine()
If szLine is Nothing Then Exit Do
'
' rest of the loop code
'
' continue: ////removed
Loop
In C you have to keep track of the {} of course therefore escaping is very
easy.
That is exactly the same without using low level coding.
Cor

Adam,
Sorry, I Did not see so fast your messag that was the same as mine
