I have one sample project to automate Internet explorer in VB 6.0. The same thing when I am trying to do with .Net its just hangs my Internet explorer document. I am not able to type or click on any control on the page.
Here is the sample code block.

Even i am not able to fire any htmdoc_focusin or focusout of DOM which was really easily accessible from my VB code.
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.

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>

View 1 RepliesI 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?
View 2 RepliesBascially, 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

View 12 RepliesI'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.

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.
