Regex:Split Problem - Must be coding it Wrong !

[rfhall50]

I must be coding my Regex:Split incorrectly. It appears to be failing on the Regex line. Code is listed below, followed by output from Log. I am getting my Log entry (hightlighted in Blue) showing the input value, but it never gets past the Regex line.

Would appreciate any help you all can give . Thank You.

Bob

Sub Activity_Create(FirstTime As Boolean)
[INDENTDim InputData() As String][/INDENT]   
   Dim RawData As String
   RawData = "Ficticious Name++Dummy Department++++++"
   Log ("RawData: " & RawData)
   InputData = Regex.Split("+", RawData)
   Log ("InputData(1): " & InputData(1))
   Log ("InputData(2): " & InputData(2))   
End Sub

** Activity (main) Create, isFirst = true **


[COLOR="Blue"]RawData: Ficticious Name++Dummy Department++++++[/COLOR]


main_activity_create (java line: 251)

[Cableguy]

this may seem a stupid question to you, but have you DIMed the InputData array?, have you tried to split with the normal string object?

 

[kickaha]

The problem is the "+". It is a special character in Regex, and if you want to match it you need to escape it with a "\" thus:

   InputData = Regex.Split("\+", RawData)

Thank you for the responnses. I did DIM it in a global declaration. Cant say as I am surprised about the "special" use of +. Can't wait to get back and try it tomorrow.

Again thank you to both.

Follow-up: Special Characters

Where can I find a list of special characters and how they are used ?

Thanks...
