VB

Dim strmystring as stirng = "record0030040acd035a856ab"

In this case I want to find 040 (but it could be 034 or 856)

VB

Dim I as interger = strmystring.indexof("040")
Next ouput the substring
Dim strsubstring as string = strmystring.substring(i)

Now my stirng looks like “040acd035a856ab”
With this string how can I output the fallowing:
040a
040c
040d

So I want the alphabets after 040, appreciate any ideas.

If you know it only needs the next 4 characters...change your substring line to this:

Dim strsubstring as string = strmystring.substring(i,4)

The second parm on the substring function means you want to pull the next 4 characters.

--- oops...I didn't read your question well enough...

You'll need to pull the whole thing like you did before. I suppose then you could loop through the string and look for the first character that is alpha...you could use the IsNumeric[^] function. Or you could figure out a way to do it with regular expressions.

Here are google results[^] for regular expressions. Here are CP Articles[^] for regular expressions. These should help you get started.

I have written it:

VB

Module Module1

    Sub Main()
        Dim Str = "record0030040acd035a856ab"
        Dim I = Str.IndexOf("040")

        For a = I + 3 To Str.Length - 1
            Dim Chr = Str(a)

            If Char.IsLetter(Chr) Then
                Console.WriteLine("040" + Chr)
            Else
                Exit For
            End If
        Next
    End Sub

End Module
