VS 2008 <'HTMLDocument'> Is Ambiguous In The Namespace <'mshtml'>

Jul 30, 2009

This line is throwing the error; Public WithEvents CurrentDoc As mshtml.HTMLDocument
Researching the error tells me that HTMLDocument isn't fully qualified. Isn't this fully qualified? If I change it to Microsoft.mshtml.HTMLDocument then it says it's not defined.

Unable To To Locate And Click A Submit Button Using Mshtml.HTMLInputElement?

Jan 31, 2012

Below is is an HTML form and below that, is a vb procedure, "LoginExamp" that enters in the username and password. I am unable to locate the button however and click it since it does not seem to show up as a mshtml.HTMLInputElement. "htmlInput.click()" never runs. How can I adjust the loginExamp code so that the button is clicked.

<form id="loginform" name="loginform" method="post" action="">
<input id="username" class="formfield" type="text" value="User Name" maxlength="40" name="Xusername">
<input id="password" class="formfield" type="password" onfocus="clearDefault(this)" maxlength="40" name="Xpassword">
<button class="subButton" onclick="javascript: submitform()">submit!</button>

Create HTMLDocument From .HTM File?

Mar 17, 2011

I would like to read a file from disk ( TEMP.HTM ) and convert it to a System.Windows.Forms.HTMLDocument.I know that I can set a WebBrowser control to Navigate to the file and then get its .Document property, but is there a better way, possibly using something in the System.IO.File space?

How To Set Attribute Value Of 'A' Tag In Live HTMLDocument With Quotes Around It

Feb 10, 2012

Bascially, all i'm trying to do is change the value of an attribute (such as the TARGET attribute of an A anchor tag) to "_TOP" if the attribute exists, if it doesn't exist, (if IsNull returns True) then I just create the attribute and set the value to "_TOP".The problem is, it almost always sets it without quotes around it, and even if i try to set it with quotes by setting .value = Chr(34) & "_TOP" & Chr(34) then what it does is it sets SINGLE QUOTES around the quotes I place (it's like a bad joke) and turns up in the HTML as '"_TOP"' (lol), and if I set it normally, its just saved as <a href="..." target=_TOP>some link</a> (without quotes).[code]I've changed the above variable names & turned vars into strings ("target") etc to make it easier to read for anyone reading.

I have wasted heaps of hours on this, MSDN docs are as usual horrid, there is no real documentation or tutorial on this stuff either. I've even tried using .nodeValue instead of .value to do the setting, but makes no difference. Also, I've tried (in the Else section) removing the attribute and re-creating + re-adding it from scratch to see if this would make a difference, but it didn't.Of course, quotes are important because if you try to perform an action (call a method) on this element or use it later, you will get the dreaded "unspecified error". I do this through the WebBrowser Control in VB6, but same principle should apply everywhere... C#/.NET/JavaScript etc as it seems to be DOM related).since posting we realized that if we pass the attribute name in uppercase, then the value is saved with double quotes around it. although this is not a real solution (just a temporary one), i am still looking for answers if anyone has one and accepting any thoughts you may have about this in this post. However, the temporary solution has created another sub question, being a post about the problems that arise from using this temporary solution. The sub question related to this temporary solution is located at the following link for those who may find it useful or interesting to read about, and for those who would like to contribute to this discussion further: Must pass uppercase to set MSHTML element attribute (.setAttribute) correctly, why? And CaseInsensitive .setAttribute doesn't work

VS 2008 From String To HTMLDocument.Links

Mar 1, 2010

I'm trying to write a function that can retrieve all the links from a webpage. I'd like to send only a string containing the URL. Basically, given a string of a URL, I'd like to "load" that into an HTMLDocument so I can access the Links collection. I just can't figure out that part.I've already written the function by using the Document in a WebBrowser. But, after selecting a link, I'd like to get its links, and so, and so on....while the user is still browsing the first page.

MSHTML System.AccessViolationException?

Sep 21, 2006

I seem to be in a quandry over an error that makes no sense to me.In following some examples I have found on the Net, I've been attempting to use the MSHTML library in vb.net to access the HTML DOM.[URL]...when I look at the error message, it tells me that memory could be corrupt elsewhere. I've attempted this line of code by omitting the "http://"portion of the URL, byt trying numerous web sites, and with various other arguments in the 2nd parameter, such as "", ControlChars.NullChar and "null". I've also reset my PC and created a brand new application with only that code and get the same results.I am using VS.NET 2005,version 8.0.50727.42I don't know if it will help, but the details from the exception object are as follows:System.AccessViolationException was caught Message="Attempted to read or write protected memory.

C# - Selecting Multiple Items In A Listbox Using Htmldocument's SetAttribute?

Jan 27, 2012

I know that I can select an option in a listbox within my HTMLDocument (which refers to a webbrowser control's HTMLDocument) using SetAttribute. For example:

htDoc.GetElementById("lstCountries").SetAttribute("value", "88")

However, I can't figure out how I can select multiple items within the listbox. When I call SetAttribute repeatedly, it always unselects the old one first.

Aug 17, 2009

Is it possible to load HTML content into the HTMLDocument object without having to use the WebBrowser control? I have an html file stored locally that I want to parse in order to find out which checkboxes are on and which are off.

All of the examples I've found use the Webrowser. It just seems convoluted to have to use the WebBrowser in order to get to a DOM object.
