Hi,

This is my first post, and I will take every caution to follow the Forum rules.

Problem Statement : I have a form with a Web browser control. I am trying to load a web-page and search for some user information once the page is loaded. The problem however is that this particular web-page has a web-dialog box, which shows up when the website is loaded for the first time.

I can't seem to find any method to suppress it.

I have tried the Web browser's setting named ScriptErrorSuppressed, and even tried Sendkeys however nothing seems to work.

The code so far is as follows :

WebBrowser.Navigate("http://xxx.net/getuserinfo/id?XXXX")

Please help...

Thanks

This is a known issue with the WebBrowser control in VB.NET. One thing you can do is to attach a handler to the Document Loaded event and within that handler, register a handler for the Error event. Here's an example of doing that

'Hides script errors without hiding other dialog boxes.
Private Sub SuppressOnlyScriptErrors(ByVal browser As WebBrowser)
	' Ensure that ScriptErrorsSuppressed is set to false.
	browser.ScriptErrorsSuppressed = False
	
	' Handle DocumentCompleted to gain access to the Document object.
	AddHandler browser.DocumentCompleted, AddressOf browser_DocumentCompleted
End Sub



Private Sub browser_DocumentCompleted(ByVal sender As Object, ByVal e As WebBrowserDocumentCompletedEventArgs)
	AddHandler DirectCast(sender, WebBrowser).document.window.Error, AddressOf Script_Error
End Sub

Private Sub Script_Error(ByVal sender As Object, ByVal e As HtmlElementErrorEventArgs)
	' Ignore the error and suppress the error dialog box.
	e.Handled = True
End Sub

Hope this helps

Hi,

thanks for replying...
tried the eventHandler, but could not suppress the web-dialog from appearing.

I have something that I wanted to try.
Probably I can read the innerHTML (documentText) as the page loads by using

Private Sub WebBrowser_ProgressChanged(ByVal sender As Object, ByVal e As System.Windows.Forms.WebBrowserProgressChangedEventArgs) Handles WebBrowsera.ProgressChanged

and stop the execution of the page once I find the code for the Pop-up (web-dialog) script.
Since I saw the source of the Web-page and the script part is written at the end.
This way, I can prevent the web-dialog from appearing, since it would never get executed...

Would you suggest that I go ahead with this or is there something simpler that I can try...
