Solution 2

Have you ever heard about RegEx[^]?

If you would like to find 2hold up, please use it:

VB

Imports System.Text.RegularExpressions

Module Module1

    Sub Main()
        Dim sText As String = "ÿÿÿÿÿÿÿÿ^2hold up.._AFC"
        Dim sPattern As String = "\b*(\^2hold up..)*\b"
        Dim rx As Regex = New Regex(sPattern, RegexOptions.Singleline)

        For Each m As Match In rx.Matches(sText)
            Console.WriteLine(m.Value)
        Next

        Console.ReadKey()
    End Sub

End Module

If not, please, let me know and i'll try to find you proper pattern.

It looks like your logic is also wrong, Maciej. OP wants to get "^2holp up". If so, it means this part of string is unknown. So, you cannot use it in your pattern. And if it is known, you would find whatever is already known, so it would be at least "if {inputString.Contains(...)} ...".

Perhaps, right answer would be: "Dear OP, you did not specify what part(s) of the string is supposed to be known?" or like this: "giving one example does not mean specification of anything...".

Solution 1

VB

Dim s As String
      s = "ÿÿÿÿÿÿÿÿ^2hold up.._AFC"
      Dim start = s.IndexOf("ÿÿÿÿÿÿÿÿ") + Len("ÿÿÿÿÿÿÿÿ")
      Dim limit = s.IndexOf("_AFC") - start
      s = s.Substring(start, limit)

Happy Coding!
:)

I think your logic is wrong... Why? Lenght is never same, so we do not know the string before and after searched string ;(

Aarti Meswania 27-May-13 9:39am

it will work
try input like this...
s = "43345345345345ÿÿÿÿÿÿÿÿ^2hold up.._AFCfgffhfhfhfhfhfhfhf"
still it will answer same

OP wants "^2hold up.." as result
in your solution you are feeding directly o/p in process, which he want as result
