View 4 RepliesI 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

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?

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).
