Select case wildcardIs it possible to compare a vaule for a select case statement using a wildcard. e.g. somthing like Select case myValue case like "*ing" end select would evaluate as true for "singing", "raining", etc. If it is possible what is the corerct sysntax (obviously I used the one above and it didn't work). Regards Michael Bond If myValue Like "*ing" Then
.... ElseIf myValue Like "*bla" Then .... End If "Like" is a little known and handy VB Operator.

ElseIf myValue.EndsWith("bla") Then .... End If Of course, you cannot use it with more complicated patterns. -- Peter Macej Helixoft - http://www.vbdocman.com VBdocman - Automatic generator of technical documentation for VB, VB ..NET and ASP .NET code Sorry Guys
I know how to use the wildcard in an "if" loop. My question was about whether, or not, it could be used in a Select Case statment Regards Michael Bond Show quoteHide quote "Peter Macej" wrote: > > If myValue Like "*ing" Then > > ... > > ElseIf myValue Like "*bla" Then > > ... > > End If > > For this particular pattern, using String.EndsWith method would be faster: > If myValue.EndsWith("ing") Then > .... > ElseIf myValue.EndsWith("bla") Then > .... > End If > > Of course, you cannot use it with more complicated patterns. > > -- > Peter Macej > Helixoft - http://www.vbdocman.com > VBdocman - Automatic generator of technical documentation for VB, VB > ..NET and ASP .NET code > > I know how to use the wildcard in an "if" loop. My question was about You mean "if" block. Not loop. ;-)> whether, or not, it could be used in a Select Case statment I don't think VB has ever supported Like in Select Case comparisons. A little interesting considering you could do so many other things with Select Case (like alphabetical comparisons using "To" etc). But, I'd be surprised if MS changed this behavior in the latest versions of VB. It's Tradition I guess. From VB.Classic documentation: Note that Is and Like can't be used as comparison operators in a Select Case statement.

(Personally, I think If/ElseIf is more intuitive though.)
