[RESOLVED] Regex is nothing ?

Hi, i have a regex below that works great

Code:

---

Dim Regex As New System.Text.RegularExpressions.Regex("<div><strong>You have (.*?)</a></div>")
        Dim matches As MatchCollection = Regex.Matches(thepage)

        For Each match As Match In matches

            TextBox3.Text = ("You have " & match.Groups(1).Value)

        Next

---

What i need to know is how to check if it returns nothing?

For example the above code lets me know if i have a private message, if i have then it tells me, if i have not then the regex wont grab anything.

In the source, if i have a message it will say "You have whatever"
If i do not then it wont have anything in the source.

I have tryed things like:
If matches.ToString = nothing
If matches.ToString = ""

but they don't work :/

Thanks for any help

Just check for the number of matches:

Code:

---

Dim Regex As New System.Text.RegularExpressions.Regex("<div><strong>You have (.*?)</a></div>")
Dim matches As MatchCollection = Regex.Matches(thepage)

If matches.Count = 0 Then
    'No matches
Else
    For Each match As Match In matches
        TextBox3.Text = ("You have " & match.Groups(1).Value)
    Next
End If

---

Of course, since you're only using one in the first place, you can use Match instead:

Code:

---

Dim re As New Regex("<div><strong>You have (.*?)</a></div>")
Dim m As Match = re.Match(thepage)

If m.Success Then
    Me.TextBox3.Text = "You have " & match.Groups(1).Value
Else
    Me.TextBox3.Text = "No new messages."
End If

---

Thanks,

If m.Success did not work but If matches.Count = 0 worked :)

Well i changed it to If matches.Count > 0 with an else statement.

Thanks :D
