I am trying to extract a portion of text from a web page that is generated by a Java script. [URL] A glance at the source of the page shows the actual display content is not directly represent in the HTML Source. I am trying to grab the auction information in the body and not the menus on the right. Can someone point me to the right object model- methods and properties?

I have some code in VB.Net that I've been using for years that has been working fine, that is until I upgraded to Internet Explorer 9. The essence of code is below. In IE8 or earler, the code works. In IE9, when it tries to execute Br.Document.Body.innerText (or .innerHTML), I get an exception "Public member 'innerText' on type 'DBNULL' not found." When I add Br to the Watch window and hit + several times to get to inerText, it actually shows the text, but if I add Br.Document.Body.innerText to Watch, it returns DBNull as the value.Because of this problem, I removed IE9 and reverted back to IE8, and the code works fine. Of course, I would eventually prefer to upgrade to IE9, but this bug needs to be fixed first.

View 1 RepliesI'm wondering if it is possible to scrape information from a word document? For example the word document looks like this:
<b>Make: </b> Audi
<b>Model: </b> A4
<b>Colour: </b> Blue
<b>End</b>
Could i create a simple tool that would be able to read this word document and look for certain text and then capture the text that appears after it?
For example if tell the tool to look for "<b>Make: </b>" and then capture what is entered after it until it reachs "<B>" tag on the next line?
I want to be able to take this info and load it into a datatable and display it in a datagridview.

i have this to basically complete a form i used getelementid but it never completes i think its due to the form type, on my first button in webbrowser1 i have similiar code which logs me in and it works fine although this form is a <form id="form" enctype="multipart/form-data"> form, should this stop me from completing it with .innertext ? due to the enctype? i would also like to be able to user innertext and take it from a TextBox9.text
how do i get around this to complete these values, my code shows no errors it just navigates to the page and dosent complete anything, button1 logins fine and the code is almost identical, except for obvious differences http address etc code edited slightly posted old unfunctional version, this is now what i have, still unfunctional but makes more sense i think
How would I use Regex to extract the body from a html doc,taking into account that the html and body tags might be in uppercase, lowercase or might not exist?

Ok the problem is with this Calc.DateLongToDateShort(tempxmlnodelist(j).Item(" _date").InnerText) < Date.Now Then If the innertext is a correct date, then the equation suceeds, however when the innerText is blank, which sometimes it will be, it throws exception cannot convert "" to Date. Now this makes sense of course. I am wondering if there is a "simple" way to avoid this error, without needing to add lines such as:

I am having issues with the following code. BrowsePage.Document.Body.ScrollRectangle.Width returns 230 even though the page is a lot bigger than this. Therefore the majority of the page is chopped off. If I replace BrowsePage.Document.Body.ScrollRectangle.Width with an integer e.g. 2000, the entire image is captured. The HTML file that is being captured (c:htmlTest.txt) does contain a few JavaScript errors:
Public Class ImageFromHtml
Private PageUrl As String
Private ConvertedImage As Bitmap
Private BrowsePage As New WebBrowser()
Public documentText As String

i have a table ... it has an identity seed that we will call "IDSeed", and also a field that specifies a default value of 5 we will call this "DefVal".Now i have written the following code that inserts a record into this table:
bs.AddNew()
Dim d As DataRow =bs.CurrencyManager.Current.row
'...THE RECORDS GET WRITTEN TO HERE
[code]....
The code above should display a msgbox that says "The item you just inserted has and ID of [AUTO ID HERE THAT WAS GENERATED] and the Value in DefVal is 5[IF IT WAS NOT SPECIFIED IN THE OTHER BIT SINCE THE DEFAULT VAL FOR THIS FIELD IS 5]"However the d.Item's "IDSeed" and "DefVal" remain dbnull ... what have i missed? I got it working for a table adapter also - what the?

i need to copy the text from a webpage into a txt file which will then be copied into a txtbox on my form (this parts done),the web page url will always be the same and the page will contain just a line of text that will chage from time to time
also i need it not to update the text file if the page displays "page cannot be displayed"i think the best way to do this is if i always start the website text and end the text with a certain "very random" word like "websitedownload" this will never come up anywhere elsealso if it doesnt copy unless the url is exactthis will stop default search engines kicking in.the website is mine/company's so this i can do
I am trying to learn a little more about reading and writing Outlook mail messages. So I've written a small app to read my mail messages and pull certain lines from the body. When I run the app I get to a certain point and start getting error messages telling me I have a limit on the number of messages I can have open. With that I figured something is not closing properly. All of the examples I've checked out (I've been at this most of the morning) I've not seen one thing where the code is closing the message after it's been read. I've included the code and as you can tell there's not much to it.
