[RESOLVED] Find Clicked Url Link/ Open Link In New Tab

Hi All,

Im trying to create a webbrowser in VB 08;

I was wondering how i would create new tab with the Link the clicked.

*EG* They Right-Click Link > Open In New Window/Tab > Makes New Tab In My Program > Navigates To The Linked Clicked.

Is there any possible way of doing this?!

Thanks In Advance,

Jamie.

Use a TabControl and when the url is clicked add a new tab and generate a new WebBrowser control in it.

Done That, But How Would I get it to navigate to the link clicked url?

Set the WebBrowser.Nagivate("siteClicked")

Thats The thing, How do i get it to find the link they clicked on ? From The Website They was on.

The webbrowser control raises a number of events when the user tries to do things such as following a hyperlink.

I havent got visual studio open at the moment but if you look at the events it raises you ought to be able to trap the appropriate event and examine the URL it is expecting to navigate to. Just intercept this and get your new browser to navigate to that URL

Sorry To be off hassle but i dont know what the event is. and how i would set it out.

OK the webbrowser control has a "Navigating" event. Like all standard framework events this passes an eventargs object - in this case its a specialised event args object : WebBrowserNavigatingEventArgs, which among other properties it exposes is "URL" telling you where it is about to navigate to.

This event gets fired before the webbrowser control actually starts navigating, so you can put code into this event, trap the URL that it is about to navigate to, create your new tab with a new webbrowser control and navigate that browser to this URL, and cancel navigation on the initial webbrowser.

Please could u give me the code ( i cant seem to figure it out ) this is my newWindow Code:

Code:

---

        Dim browse As New WebBrowser
        TabControl1.TabPages.Add(i, "Page" & 1)
        browse.Name = "wb"
        browse.Dock = DockStyle.Fill
        TabControl1.SelectTab(i)
        TabControl1.SelectedTab.Controls.Add(browse)
        i = i + 1
        e.Cancel = True

---

I have got it to cancel the internet explorer to open but cant get/set the url.

How is this code called? ie is it being called from an event and if so what event?

Private Sub WebBrowser1_NewWindow(ByVal sender As Object, ByVal e As System.ComponentModel.CancelEventArgs) Handles WebBrowser1.NewWindow

OK the NewWindow event doesn't reveal the URL so you'd need to get the URL from a different event. Here's an example which grabs the URL you are about to navigate to from the Navigating method and then displays that in the NewWindow Event :

Code:

---

Public Class Form1

    Private _URL As String

    Private Sub WebBrowser1_Navigating(ByVal sender As Object, ByVal e As System.Windows.Forms.WebBrowserNavigatingEventArgs) Handles WebBrowser1.Navigating

        _URL = e.Url.ToString

    End Sub

    Private Sub WebBrowser1_NewWindow(ByVal sender As Object, ByVal e As System.ComponentModel.CancelEventArgs) Handles WebBrowser1.NewWindow

        MessageBox.Show(_URL)

    End Sub


End Class

---

So you ought to be able to combine that code with your own code to use _URL to navigate your new browser.

would this by any chance work:

Code:

---

    Dim i As Integer = 1
    Public _URL As String
    Private Sub WebBrowser1_Navigating(ByVal sender As Object, ByVal e As System.Windows.Forms.WebBrowserNavigatingEventArgs) Handles WebBrowser1.Navigating

        _URL = e.Url.ToString

    End Sub
    Public Sub WebBrowser1_NewWindow(ByVal sender As Object, ByVal e As System.ComponentModel.CancelEventArgs) Handles WebBrowser1.NewWindow
        Dim browse As New WebBrowser
        TabControl1.TabPages.Add(i, "Page" & 1)
        browse.Name = "wb"
        browse.Dock = DockStyle.Fill
        browse.ScriptErrorsSuppressed = True
        TabControl1.SelectTab(i)
        TabControl1.SelectedTab.Controls.Add(browse)
        e.Cancel = True
        AddHandler WebBrowser1.Navigating, AddressOf WebBrowser1_Navigating
        AddHandler WebBrowser1.DocumentCompleted, AddressOf browse_done
        browse.Navigate(_URL)
        i = i + 1
    End Sub

Looks good at first glance but the best way to find out is to try it...

(NB not sure why you've made _URL public - if you want to expose it as a property you should give it a "proper" name such as URL)

For some reason it doesnt. it just displays a white page.

OK a couple of things.

I'd put a breakpoint on the line browse.navigate(_URL) and check that a) the line is being run and b) check what _URL evaluates to.

EDIT - also, when you are adding handlers you don't seem to he adding to the new browser control.

right it does get the link + what do u mean adding to the new browser control?

You are creating a new browser control with this line

Code:

---

Dim browse As New WebBrowser

---

These two lines are adding event handlers dynamically

Code:

---

AddHandler WebBrowser1.Navigating, AddressOf WebBrowser1_Navigating
AddHandler WebBrowser1.DocumentCompleted, AddressOf browse_done

---

Which is all well and good, but you are adding event handlers to WebBrowser1 (which I'm guessing is the default webbrowser on the 1st tab?) and not your new webbrowser. If you want to add the handlers to your new WebBrowser then I'd expect it to be

Code:

---

AddHandler browse.Navigating, AddressOf WebBrowser1_Navigating
AddHandler browse.DocumentCompleted, AddressOf browse_done

---

good point, ill try.

right that does work but when u try do that on the tab u just made it just open it in Internet explorer.

OK... lets take a step back...

how does the user activate this functionality? when they right-click on a link are you implementing your own popup menu or are you using the browser's built in popup menu?

the built in one. + thats extremly weird, i havent changed nothing and its stopped working

ok well im off to bed, due to me having work in the morning, but please could u help as much as possible while im gone.

Does the initial browser (the one created at design time) work differently from the new (dynamically created) one?

Fraid not - I too have work in the morning (and a 100 mile trip to get to work) - while I'm happy to help you identify where your code isn't workign, I'm not going to spend the night beavering away at your problem while you snooze!

well im finally back lol, lets get this thread showing again

right ive got it to add a new tab + navigate to A url but the url is the tab u just selected the link from
E.G on tab at a page for a google search "visual basic" u right-click on a link > new window > it will navigate to the google search page.
