Web Browser - Handles NewWindow

[nzwogboy]

Hi I have created a web browser and am trying to get the link that is clicked that would normally open in a new window to open in the current window as I do not want to open any other windows or tabs. This is the code I have so far and it seems to work well kind of anyway, it opens the last url not the new one. Sometime it will open just an advert, it seems to open what ever link was last loaded on the site. Here is the code:

Private newURL As String

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

        newURL = e.Url.ToString

    End Sub

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


        'MessageBox.Show(newURL)
        browser.Navigate(newURL)
        e.Cancel = True
    End Sub

I got the code from this thread http://www.vbforums.com/showthread.p...wser+newwindow

Anyone know what I am doing wrong.

Should I not be using the

browser.navigating

or the

e.Url.ToString

ie is there something else I should be using?

I am starting to think that the code

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


        'MessageBox.Show(newURL)
        browser.Navigate(newURL)
        e.Cancel = True
    End Sub

Is running before

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

        newURL = e.Url.ToString

    End Sub

Is that what I am doing wrong?

Your problem has a very easy answer. Read up on the MSDN documentation for webbrowser.navigate() method. You will find that this method has an overload that looks like this : webbrowser.navigate(url as system.uri, newWindow as boolean). So what do you think

webbrowser1.navigate("www.google.com", True)

would do?

Sorry I just noticed I did not explain very well what I am wanting to do, I am using the "Navigating" rather than navigate" as I want to get the url that was clicked as the url will come from the webpage not from my code. Here is an example, if using IE or an other normal web browser you visit www.trademe.co.nz (NZ's ebay) and you click on the advertising on the right hand side you will get a popup that takes you to the adverts website. What I want to do with my browser is instead of having a popup I want to cancel it (which is working in my code) and then get that url and navigate to it in the current browser. This is currently kind of working but it seems to run the

browser.Navigate(newURL)

before it actualy loads the new URL into

newURL

.

I am 90% sure if I get the

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

        newURL = e.Url.ToString

    End Sub

running before

browser.Navigate(newURL)

but after it handles a new window it will work, but can't seem to get my head around this.

Thanks for your help.

Tough, but not impossible.

In browser_navigating() set a flag that indicates that you successfully caught the URL. Then check for the flag before doing browser.navigate(newURL)

The actual issue here is that the managed browser control does not properly handle the NewWindow2 event of the underlying webbrowser control. This event has a parameter to allow you to redirect the popup to your own browser window instead of a popup IE instance. For whatever reason (probably compatibility with older IE versions) this functionality does not exist in the browser control as it is now.

I do have an extended managed browser control that exposes NewWindow2 and you can find that here.

It allows you to have your own form with a browser control in it intercept new window calls from your main browser, and display everything in your own forms, which of course can give you more control over things.
