Split a String

[Roshawn]

Hi,

I am retrieving a list of book titles from a web service. What I'd like to
do is shorten the titles, if possible. For example, there is a book titled
"Malicious Mobile Code: Virus Protection for Windows". It would be nice if
I could trim the title down to the colon (it would just say Malicious Mobile
Code).

Is there an easy way to accomplish this task?

Thanks,
Roshawn

Maybe you could use the instr() function to return the first occurence of the
colon, and then use the left or mid function to return the left side of the
name?

mid:

left:

instr:

Does this help you?

Roshawn,
In addition to the VB runtime functions r_burgess suggested.

You can use String.Split to split the name.

Dim title As string = "Malicious Mobile Code: Virus Protection for
Windows"
Dim parts() As String = title.Split(":"c)

The parts(0) will contain "Malicious Mobile Code", while parts(1) will
contain " Virus Protection for Windows"

Alternatively you could use String.IndexOf & String.SubString along with
String.Trim to remove leading & trailing white space.

Dim title As string = "Malicious Mobile Code: Virus Protection for
Windows"
Dim index As Integer = title.IndexOf(":"c)
Dim parts(1) As String
parts(0) = title.Substring(0, index).Trim()
parts(1) = title.Substring(index + 1).Trim()

Note you can use String.LastIndexOf if you want to split the name on the
last ":" instead of the first ":" if there are multiple ":" in the name.

I normally avoid mixing the VB runtime functions (InStr, Left, Right, Mid)
with the String methods (String.IndexOf, String.SubString) within the same
function/class/project/solution as the runtime functions are 1 based
indexes, while the String methods are 0 based indexes.

Hope this helps
Jay

Thanks guys (and gals just to be polite) for your prompt responses. These
techniques are just what I was looking for.

Very nice. I didnt even think of those calls. Learn something new everyday.
