Place A HTMLElement In A WebBrowser Document?
Apr 1, 2010
I have a Web-browser Control in My Form , in Which i am showing one HTML Page .
>>That HTML Page Contains Several Anchors.
>>As per my Requirement user Can create An Anchor by providing The Appropriate data like "Id", "Href", And "Value" .
>>for providing Those Values i have an Input form.
>> Now after Providing That Data .User has to select the Position By Selecting The Previous Anchor And Next Anchor.
i am Getting All The Anchors In the Document From The Following Code
For Each Elem As HTMLElement in WebBrowserDoc.Document.GetElementsByTag("a")
CmbTag.Items.Add(Elem.innerText)
Next
Now i want to place an anchor in between user selected Anchors.

I am trying to get the HTML inside a HTMLElement which has an id "block". I have tried:
If webbrowser1.document.getelementbyid("block") isnot nothing then
MsgBox(webbrowser1.document.getelementbyid("block").innerHTML)
end if
But it keep throwing a NullReferenceException and tells me to check if it null/nothing which is what I'm doing.
So how do I check if an element in a HTMLdocument with a certain ID exists?

I am having some problems with Navigating to the same URL of the WebBrowser.I am trying to get an HtmlElement from the WebBrowser. This HtmlElement is a simple link ("href"). The link is shown on the site that I am navigating to, every hour for only 1 minute and than disappears.I want to check every 15 seconds if this link exists. So, I am doing a loop with a Timer and refresh the WB control.The problem that I encounter is when the WB control already navigated to the site that I wanted to check, it always navigate to the same page when refreshing. The links or the DocumentText are never changed, even if I enter Internet Explorer and see that it has been a change in the page.

I am trying to get position of html elements in a .net's webbrowser control and failing, i need the exact position of the element relative to the whole document or the webbrowser control to be able to send a mouse click using SendMessage() P/Invoke..I have tried the solution from here but it didn't work:getting absolute position of HTML element in webbrowser control with C#.I am guessing that is because the page relies on very complex ajax and css.the function "WebBrowser1.Document.GetElementFromPoint()" works just fine in getting the accurate html element, i just need the opposite of it.other wise, should i just keep on searching using "GetElementFromPoint()" until getting the correct element?

I am working on a project that involves the editing of html of pages on the fly. I have put a webbrowser on the form, and I am able to retrieve the element under my mouse by using: wBrowser.Document.GetElementFromPoint(e.ClientMousePosition) in the Document.MouseClick event.However, I want the experience to be more intuitive, by placing a semi-transparent blue rectangle over whichever HtmlElement the mouse is currently hovering over. I created a borderless form with 20% opacity for this, which works great, except that I cannot for the life of me figure out how to calculate the screen coordinates of the element under my mouse. Here is what I have so far, but while the size is adjusted correctly, the location of the rectangle is just stuck at (0, 0) relative to my form. Highly annoying:

I am grabbing an HTMLElement from a browser object and then using getElementById to grab the element I want. When the element is grabbed into the HtmlElement object double quotes around attributes like <input type="checkbox" name="test1" /> becomes <input type=checkbox name=test1>.It is removing the double quotes and backslash from the HTML available in the HtmlElement. Is there anyway to get the HTML element from Visual Basic .NET code and keep the true HTML formatting?

I need to click an image in a webbrowser from a Windows Form in VS 2010.I can click ordinary links using code such as this one:
Private Sub Button14_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button14.Click
Dim lnk As HtmlElement
For Each lnk In Form2.WebBrowser1.Document.Links
If lnk.InnerText = "the_text_of_the_link" Then
[code]....
When it comes to the second variation of the code I often get the following error message (exception):NullReferenceException was unhandled Object reference not set to an instance of an object.
Basically - how do I tell it to click on it only if there are two separate and unique strings of html code in a html tag?

I have been trying to switch my code from using an ie object to using a built in webbrowser. Most of the properties are the same but I have run into an issue getting an xmldocument from a page.
'Internet Explorer Object
Dim oXML As Object = oIE.document.XMLDocument
nodeList = oXML.SelectNodes(path).length
Trying this method on webbrowser obviously doesn't work. But does anyone know the path to get the XMLDocument object from webbrowser?

In a webbrowser control when I set the document text, either by ebBrowser1.Navigate(file_path) or WebBrowser1.DocumentText = String it instantly calls WebBrowser1_Navigating and this blanks the document.The document will load properly if I remove the _navigating method, but I need it for other purposes

I use the webbrowser control in my program but when after navigate to a site. I try to get some element on the using the document of the webbrowser (like getelementbyid ... ) I notice that some element are missing. I know that elements are dynamically inserted into the page by some javascript. I searched method to get those element and I try to get them injecting a javascript to be executed in the page and return some element by window.external method (or just to try by alert) but even if this script are executed they just return the same result as the method on the document in the original code. Is there a way to access to this 'invisible' element in my program in some way just like I access them by pressing F12 in Internet Explorer?
Here is my code:
private void button2_Click(object sender, EventArgs e) {
//injecting and executing my javascript code
HtmlElement head = webBrowser1.Document.GetElementsByTagName("head")[0];
HtmlElement scriptEl = webBrowser1.Document.CreateElement("script");
IHTMLScriptElement element = (IHTMLScriptElement)scriptEl.DomElement;
[Code] ....
At the end of the execution both test and test2 have the same html were some element are missing.

I have a Word document in a WebBrowser. I modify the doc and save it with another name in another path. Finally I close my form and put my doc as nothing. My problem is that a dialog box appears sugesting me saving the changes (the changes done in the initial path) but i have already saved my document so I always want to select "No", how can I avoid this dialog box? Or if it isn't possible, how can I automatize this action?

I need to get the url of the webpage the webbrowser is navigating to, but since the code executes faster than the webbrowser navigates to the webpage, it gets the url of the last page. I cant use DocumentComplete Event because i have a tabbed browser,
and i cant write events because im creating tabs(with webbrowsers) at run-time. So how would i check to see if the webbrowser has loaded a document?

I used to use Visual Basic 6.0 to look up a webpage with Web Control, then I would paste the Text from that into a RichText document....then I would parse it down to what I was looking for. Now that I'm getting back into programming again, I have been trying to repeat this process with Studios 2010...but with little success so far.

I have this code set up to navigate to a certain .html document depending on what's selected from a ListBox:
Private Sub FileList_SelectedIndexChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles FileList.SelectedIndexChanged
HelpWindow.Navigate(System.AppDomain.CurrentDomain.BaseDirectory & "help" & fileArray(FileList.SelectedIndex, 1))
End Sub
The problem is, when I first select something in the ListBox, it successfully navigates to that file and displays it. But when I select something a second time it doesn't change.
All of the paths it's trying to navigate to are correct. I've checked this 1000 times.
