this does help, but i need it to search the entire html text and find the number

Have you tried this example?

Have you tried changing the searchstring to something similar:

Code:

---

Dim searchstring As String = WebBrowser1.DocumentText

yea i tried that, but it came up with no results

Try this as your regular expression:

Code:

---

id=(\d+)&?

the regex.match function returns only the first match found in the string. If you want to find all matches from a string, call regex.matches function instead and it will return a matchcollection which you can loop through each match and read the value.
