You want to add the URL from the textBox to the listBox? Or are you trying to get the searched words out of the Google URL? I cant really tell what your trying to do.

Try looking at this:(The reply's are at the very bottom)
regEx for pulling out google links : c# google
its in C# but you should be able to convert it.

Private Sub test14()

	Dim w As New WebClient()

	Dim pageSource As String = w.DownloadString("http://www.google.com/search?hl=en&q=weather&start=0")

	Dim s As String = "(?<=<h3 class=r><a href="")([^""]+)"

	Dim re As New Regex(s)

	Dim m As MatchCollection = re.Matches(pageSource)

	For i As Integer = 0 To m.Count - 1

		Debug.Print("Match result {0} is ""{1}"".", i, m(i))

	Next

End Sub

well this is converted and uses webrequest i want to use web browser :( and its a bit confusing for me

You can still use your webBrowser just change this line

Dim pageSource As String = w.DownloadString("http://www.google.com/search?hl=en&q=weather&start=0")

to something like:

Dim pageSource As String = w.DownloadString(webBrowser1.Url.ToString())

Then when some clicks the search button or whatever, just call the function.

i just want the url "http://www.ourbrisbane.com/see-and-do/places-to-see/valley-lakes" this thing out of this from all sites how to make regex for this?


m doing it like
Dim r As System.Text.RegularExpressions.Regex((""<a href=""http://.*"" class=""l"")

but i get the error how to fix it?

[CommittedC0der]

Hmm the Regex looks fine to me, could you post the error your receiving?

[martin2311]

the error says array bound cannot appear in type specifiers

this source i took from mozilla firefox but the source i get using internet explorer is different how to get that fixed?

If you are wanting just URL addresses, the following regular expression should work:

((?:http|https)(?::\/{2}[\w]+)(?:[\/|\.]?)(?:[^\s""]*))

Although I think you may need to be a little more specific, are you wanting more than just the URL?
