I have programmed a web browser with Visual Basic 2010 Express and came across a major bug. Whenever I try to click a checkbox on a certain website, this error message appears:
An error has occurred in the script on this page.
Line: 193

Do you want to continue running scripts on this page?
[Yes] [No]
After clicking yes or no it just pops up again and I have to open the Task Manager just to close the browser.

View 1 RepliesI have a question regarding clicking a button on a web page through the web browser control in VB .Net Express Edition. I have figured out quite a few tricks and stuff with the web browser control but I can't figure out how to automatically click a button. I know I can invoke the 1st instance of a "submit" type button but I want to click the 3rd instance (or chose which ever one I want). Unfortunately the button declarations in the HTML don't have ID or NAME tags to make it easy to pick them. How would I go about extracting all the buttons on a form in an array form, so I could invoke a certain member of that array and click a button of my choosing. Is this possible?

I'm using Visual Studio 2005, net framework 2.0, Microsoft Internet Explorer ver 7.0.5730.13. Create a form with the webbrowser control and two buttons. Use the code that i provided at the end of this question to understand the scenario. As far as i know, this behaviour happens only on the myspace.com web site. 1. Navigate to your myspace.com inbox page, read a message and click on the reply button to reply to the message. The page will show correctly in the web browser.2. Then click on Button1, repeat the same process (read a message in the myspace.com inbox, click on the reply button), and the textboxes where you have to enter your reply will be gone.3. Then click on Button2, repeat the same process, and the page will show correctly in the web browser.4. Then comment out or remove the oDoc_MouseDown event, click on Button1, repeat the same process, and the page will show correctly.Why does the page shows correctly when the oDoc_MouseDown event is removed? The same behaviour happens if you use any other event of the oDoc variable.I desperately need the page on myspace to be shown correctly with the oDoc_MouseDown event and other events of the oDoc variable. Please provide a solution to this

I'm trying to set up a WebBrowser control so that it will respond to the user pressing the mouse's Forward or Back buttons and navigate accordingly, regardless of where the cursor is located in the form. The WebBrowser control doesn't have any click event handlers, and I couldn't add one with AddHandler, so I'm not sure what to try. Searching here, I read about GetAsyncKeyState which can be used to get the status of the mousebuttons, but I don't know how I would use this to code an event handler for these buttons.
View 15 Repliesthis is button 1:
WebBrowser1.Navigate("javascript:OnClick(go(512,5))")
this is button 2:
WebBrowser1.Navigate("javascript:OnClick(go(513,5))")
i try:
WebBrowser1.Navigate("javascript:OnClick(go(512,5))")
WebBrowser1.Navigate("javascript:OnClick(go(513,5))")
But this presses only on the second button ("WebBrowser1.Navigate("javascript:OnClick(go(513,5))")")
and not on two of the buttons.
How could I make it where I could accurately go forward and backward? Whenever you press back once, then back again, it takes you to the page you started with. So how do you make it where it can go back as many pages as there are and then tell if your a the highest or last page when going forward?
View 1 RepliesI have a problem to enter a web site by program and not manually. I just navigated WebBrowser1 to a web site. After the navigation there is a button in the site. The button will send me to a link if I will click on him. I got the link path (After calling to a Sub doing it) in a String call SitePath. Now after I got the button's path I tried to navigate the WebBrowser again to the new path. But, the WebBrowser navigates again to the same Web Page The Site do not let me to enter the link by program only manually when I click on the button. Is there a way to click on this button by program or other way to enter the path?

I am trying to get my Visual Basic Web Browser to open links and buttons when clicked in a new window of my web browser by using the New Window event. I found this code to make links work in a new window of my browser, but buttons will not. When I click on a button, a new window of my form pop ups but the url says, "about:blank". Is it because the attribute is set to "href"?
Private Sub WebBrowser1_NewWindow2(ByVal sender As Object, ByVal e As System.ComponentModel.CancelEventArgs) Handles WebBrowser1.NewWindow
Dim myElement As HtmlElement = WebBrowser1.Document.ActiveElement
Dim target As String = myElement.GetAttribute("href")

View 1 RepliesUsing VB 2008 Express.
Attaching code to buttons when they're clicked is easy when they're static buttons on the form; just double click the button on the form designer and add code to the event.
I have a series of buttons that are generated in a control array, so they're generated in a class, and in the form there are no buttons until runtime.
So newbie question with a probably simple answer...how do I enter code for the click event for buttons that aren't there until they're instantiated as a class at runtime?
