View 1 RepliesHow to retrieve the absolute coordinates of an HTML or CSS element from the webbrowser control using Visual Basic? I am using VB 2008 Express Edition. I would like to be able to display the control in my application and then using the HTML Document Object Model (I guess?!) get the X and Y coordinates (top, left, bottom, right) of a DIV or other HTML tag.

Is it possible to obtain these input elements during an httpwebrequest without having to view the html code?
This may sound really stupid but I have to ask cause I'm not finding this answer anywhere.I have an application where the user will need to sign up for a new user account on the website [URL]..However when I am using Firefox's plug-in Firebug to view html I am getting something totally different than when I just right click on the site and view the page source.
What I am trying to do is to get the captcha from the website and display it in a picturebox on the application so the user can view the captcha, solve the captcha and then the app post is back to the service for a response.
Here is the source that I am getting using Firefox's Firebug to inspect the element:
<td>
<input type="hidden" value="Oo3Jo1I8bgzK68agMqo3s79ZZib2OkbK" name="iden">
<img class="capimage" src="/captcha/Oo3Jo1I8bgzK68agMqo3s79ZZib2OkbK.png" alt="i wonder if these things even work">
</td>
[Code]...
Why would the two be showing me two different versions of the HTML?
And how would you be able to grab that source to view in a picturebox using webclient?
Let's say I have the following class structure (simplified from my real-world problem):
Public Class PC_People_Container
Private _people_list As New List(Of PL_Person)
Public Sub New()[code].....
If I were to serialize this, I'd get the default assigned node names in my XML. That means my root is named PC_People_Container and each person in the list is marked up as PL_Person. I know I can change the root node using <XmlRoot(ElementName :="PeopleContainer")>. The trouble is doing that for the subclasses. I can't use the <XmlRoot> tag on PL_Person class because there can't be two root elements, and IntelliSense throws a fit when I try to use the <XmlElement> tag on a class like I would on a property. Is it even possible to control what those subclasses are named when they're serialized as child nodes?
I have an XML file where some of the elements have periods in their names. Using the code below, I receive the error:
"System.ArgumentException: Child list for field Stock cannot be created"It successfully reads the file if the periods are removed( i.e. StockAdjustment instead of Stock.Adjustment)
Dim myXMLfile As String = "C:file.xml"
Dim ds As New DataSet()
Dim fsReadXml As New System.IO.FileStream(myXMLfile, System.IO.FileMode.Open)
Try
[code]....
Is there a way to handle elements with periods in their names?
I have only recently discovered the world of fetching online data using XML functions in VB.NET and it has been working well so far. Unfortunately I have hit a hurdle and am unsure as to how I should proceed. Until now I have been working with simple XML files where there was only 1 value to retrieve with a specific XML element path. Now I have an XML which looks like this (apostrophes to represent indentation):
<?xml version='1.0' encoding='UTF-8'?>
<eveapi version="1">
''<currentTime>2007-12-12 11:48:50</currentTime>
''<result>
''''<rowset name="characters" key="characterID" columns="name,characterID,corporationName,corporationID">
[Code] .....
I need to have the program assign the first row's name attribute to one combo box, the second to another combo box and the same with the last.
What I'm trying to do is more complex than this, but I'm trying to get over this hurdle.[code]...

But there was no message. How would I get the value of an HTML element inside my webbrowser?
I have been at it for few weeks now and just learning XML and VB but seems like I hit a road block. I tried a few different attempts at doing this and I have no problem displaying the XML file on a webpage using the xpathnavigator class. But then i needed to format into an html table so i took another route and just added the xmldatasource with a formview. So here is my code for that

When I click button 1 for the first time I recieve the error "Object reference not set to an instance of an object." but when I click it the second time it returns the elements text perfectly.
I thought the wb.document element might not be instantiated so I've tried navigating to a page (google's homepage) before loading the page I want put with no success.
I also thought that maybe it wasn't giving the page time to load so I added the sub to deal with the documentCompleted event but this also returns nothing (though wb.document.url is set correctly to the webpage I want)
I was looking at a previous post and the poster was talking about htmlelement, so what I want to know is if you can use this function to find a html element on a wb page.I'm trying to make a program that will find the img src url for an image on a website and then return that url to the imagelocation of a picturebox.
