Im going to be very specific... (string finding/manipulation)

Alrighty,

I am ALMOST finsihed with the current program i am writing, i need to do one simple thing:

I have 51 of these: http://vnboards.ign.com/user.asp?usr=<number> strings in a textbox, Now, im looking to use ALL 51 of thoes strings, but first i need to recognize them, I know exactally how to find the FIRST string, and take what i need from it, but i cant say the same for all the others... im using this to find the first string right now:

Code:

---

Function finduid()
Dim iEnd As Integer
        spam = TextBox2.Text
        Dim inner As String = "/user.asp?usr="
        uid = (spam.Substring(spam.IndexOf(inner), 25))
        uid = (Mid(uid, 15, 25))
        iEnd = uid.LastIndexOf(">") - 1
        uid = uid.Substring(0, iEnd - 0).Trim
        Trim(uid)
    End Function

---

But i have no idea how to even begin to search for the next string, or the string after that...


Also, how could i check for repeat strings?


Any help anyone could offer would be great!

thanks a ton :)

ok i'm assuming you have the items listed in the textbox below eachother , like this :
http://vnboards.ign.com/user.asp?usr=1
http://vnboards.ign.com/user.asp?usr=2
http://vnboards.ign.com/user.asp?usr=3

with that in mind you can do this :

VB Code:

Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
        Dim i As Integer
        Dim strString As String
        For i = 0 To TextBox1.Lines.Length - 1
            strString = Split(TextBox1.Lines(i).ToString, "=")(1)
            MsgBox("the user's number is: " & strString)
        Next
 
    End Sub

Hmmm, will split return all the instances of that string?

Also if it makes a difference, im pulling all of this information out of an HTML page

Oh didnt see that, no, they are not listed below eachother

Use regular expressions!

VB Code:

For Each m As System.Text.RegularExpressions.Match In _
            System.Text.RegularExpressions.Regex.Matches(sSearch, "(?<=\?usr=)-?\d+\.?\d*")
 
            Process(m.Value)
        Next

sSearch is the string you want to search, and Process is just a function that does something with the value. (You can just use it in code and not call a function...) That regular expression will match negative numbers and reals, as well as plain old positive integers.

'Ah hmmm, ill play around with that tomorrow, thanks :D
