[2008] Find all strigns of a certian length?

[Deathader]

Hey!

What I'm trying to do is scan a txtbox, and add all the strings that are 32 chars long to my listbox. I found this function:

   Public Function GBA(ByRef strSource As String, ByRef strStart As String, ByRef strEnd As String, ByVal lstAdd As ListBox, Optional ByRef startPos As Integer = 0) As String
        Dim iPos As Integer, iEnd As Integer, strResult As String, lenStart As Integer = strStart.Length

        Do Until iPos = -1
            strResult = String.Empty
            iPos = strSource.IndexOf(strStart, startPos)
            iEnd = strSource.IndexOf(strEnd, iPos + lenStart)
            If iPos <> -1 AndAlso iEnd <> -1 Then
                strResult = strSource.Substring(iPos + lenStart, iEnd - (iPos + lenStart))
                lstAdd.Items.Add(strResult)
                startPos = iPos + lenStart
            End If
        Loop

        GBA = ""
    End Function

But it doesn't really help me :P

I also found

 if string1.length = 32 then....

but I don't know how I can use it.

Thanks,
Alex

You've got it right there!

If String1.Length = 32 Then ListBox1.Items.Add(String1)

String1 is nonexistent. I was just using it as an example

I think I found a way how to do this, but I need to be able to use wildcards.

Are there any wild cards for vb.net?

eg.

If I searched for "12345##", "1234582" would be true
if I searched for "abc*", abcf3jffn___safn" would be true
if I searched for "abc^g#", "abcxg8" would be true

Yes, use regular expressions.
