Click Hyperlink On A Webpage Using Tag ID?
Aug 6, 2009
I am developing a program that will get specific hyperlinks, using regular expressions, from a website. It follows by visiting those chosen links and it loops through each one. Each time it has to navigate to that url to click another link in order to obtain information about that link.
The "chosen" links have been collected in a database. The fields of the database are "hyperlink" etc. and below is a prototype of what I planned on doing. Unfortunately I get this runtime error: "Object reference not set to an instance of an object." on the line indicated in the code.
For Each Record As DatabaseDataSet.Table1Rows In DataBaseDataSet.Table1
Dim website As New WebBrowser
'Navigate to the "chosen" link found in the field "hyperlink" of record
website.Navigate(record.hyperlink)
[Code]......

I have seen several threads about automating several aspects of html elements (buttons, textboxes, checkboxes, radio buttons etc...) but I didn't see any specific codes to auto-click "Hyperlinks". How would I invoke a click on any hyperlink located on any given webpage if I needed to?

As a follow up to my previous question Putting together a tricky SQL query
since I now have the records returned as URL format, how can I display those as hyperlinks in my gridview? (this is how the client wants it done, not much I can say to change their mind)
My vb code is:
Dim pds As PagedDataSource = New PagedDataSource()
GridView1.DataSource = pds
GridView1.DataBind()

I'm using getelementbyid, and basically I want to click a button but I can't find the name of the button so I can use invokemember("click")
So what I was thinking was, if someone can tell me how you click a textbox on a webpage automatically, and then you could senkey the enter button so it submits it.[url]...

Though I am using a webbrowser control at present but I want to remotely login without opening any browser nor a webbrowser control.Now I could hide the webbrowser control but then I wont know whether the site loading operation was successful or not (in case the site was down or so) Is there a function or a value that is returned after successfully loading a website via which I could check (without opening anything) whether my operation was successful or not

I have developed an asp.net website in VS2010. The defaultDocument is set to default.aspx in the root directory, as I have dome many times before.For reasons unknown an asp:button in default.aspx is not firing correctly when the url is typed in without the file extension. For example, if I type the url www.mywebsite.com the default.aspx page will load as expected, however, the button will not fire (it does postback but doesn't fire the server click event).If i type in the url www.mywebsite.com/default.aspx it works as expected.The problem I'm having only occurs in a live environment (I cannot recreate the error on the localhost).

I have some code that broadly looks like the following ...
WebBrowser1.Document.All("btn_submit").InvokeMember("click")
WebBrowser1.Document.GetElementsByTagName("select").Item("id_pickupdate").SetAttribute("value", "2011-07-07")
I cannot seem to get it to work in one code routine. I end up having to have a separate button to set the date after the page has loaded. I have tried all the blog posts using isbusy, timer etc but it does not seem to work. The code breaks and the error prompt says that id_pickupdate does not exist.

First, I launch a website in Internet Explorer from VB.net and automatically login the user with ther username and password. As soon as the username and password fields are automated, I send "enter" to the website so it goes to the next website. This part works perfectly. However, my problem is that i want to send a mouse click event, which i have already written, to click a hyperlink on the next website page. I tried a few different things, none of which worked. My program is automatically logging in the user and doing the mouse click event at the same time. I have tried to use the "sleep" command, but the mouse click event is still not executing after the second webpage loads. I have tried using nesting "If, then" statements and that has not worked either. Does anyone know how to make sure the webpage fully loads before executing a sendkeys routine or a mouse click event? This is my code thus far:
If (Search.ComboBox1.Text = "IWR") Then
BlockInput(True)'this disables the mouse and keyboard
Dim IE As New Object
[code].....
There are no errors, everything is just executing all at once instead of letting the second webpage load and then executing the mouse click event.
