C# - WebBrowser Control Document Seem To Be Incomplete
Apr 17, 2012
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?
How can I open an Office Document in a webbrowser control? when i tried to navigate the file location... it always prompts the save dialog box... how can i plainly view the document file in webbrowser control?
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.
I am using webbrwoser control to open Word document for editing on winform using vb.net. (vs 2005). Now once user edit the word document, I want to forcefully save that edited document to my document when user directly close win form or user will try to EXIT. Unfortunately, word doc which open on webbrowser control if it is edited and when winfrom is being closed it won't ask us to save where as independent word document aske to save changes. I tried to call method "ShowSaveasDialog()" of webbrowser control on winform close event it did not fire up.
I wrote a VB.Net application that displays HTML help files according to user's search results.A user types some keywords and receives a list of HTML help files containing these keywords.When a list item is selected the HTML file is displayed in WebBrowser control.The problem is that I cannot mark the keywords in the displayed HTML file. I need to highlight them like in a standard Help. I tried many options and nothing works.If I change HTML element style manually (background color for a specific string) all pictures attached to this page are not displayed. After "Refresh" operation the pictures are displayed but the text selection is not enabled.I hope there is a standard function for this operation but I cannot find it.
I'm currently working on a reporting app that saves a report to HTML, then sends it to a PDF printer.First off, to render the HTML I am using a webBrowser control:
Dim _renderer As New System.Windows.Forms.WebBrowser
To print the HTML document, I am using the WebBrowser.Print() function
webbrowser1.document.body.outerhtml This transforms all the tags into uppercase and removes quotations. I need to make it valid xhtml does anyone know away to get the outerhtml to not format or maybe a way to easily change the output to proper xhtml.
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?
I have the HTML like below in a webbrowsercontrol, and im trying to get all the email address out of it, so anything with a @ in it.
<head</head> <body> Here is some test testing@myspace.com here is more text email@email.com. </body>
There could be tables etc in the html, but it shouldnt matter. i was wondering if there is a way to check if there is an @ if there is get all text to right and left until space, or any letter or number...?
I had this but wanted to see if there is a better way.I have a problem with the below also, it dosent seem to bring back anything even though i know there are emails on the page
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
Is there a way to check if an element is in the webbrowser1.document ?
I can click the button fine, IF the element is on the page, but sometimes i get to the end page, where i just have the "back" button, and no forward button.[code]...
i am trying to set up and start the timer for few seconds then refresh the page on the webrowser when the webbrowser document is complete. Here it is the code:
Code: Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click Button1.Enabled = False Button2.Enabled = True WebBrowser1.Navigate("www.test.com") End Sub
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.
if i webbrowser1.navigate "[URL]" when this page was loaded then automatically navigate to [URL] i try webbrowser document completed event but still not working
I am writing a few web based apps which will require a webbrowser extension. I have already used the IE webbrowser control that uses the trident web rendering engine. I believe this is MSHTML.DLL? Anyway, some of the users of my programs have complained of a few things. Particularily,
1. It seems to be a slow browser, at least compared to other rendering engines out there (webkit and gecko are 2 known ones).
2. On the developer side, it seems to be low in features. The features are sufficient in most cases, but there are some "special" things that I need.
3. It has VERY low HTML (and especially HTML5) compliance.
My question is, how much work would it take to use a different engine (such as webkit .net, which I HAVE heard of) and be able to distribute it easily. Or, if you guys feel ambitious, we could try writing a brand new engine ourselves. I know how big of a job it is, and frankly, I have no clue where to begin. I would just like your thoughts and opinions on the matter.
i have created an app to load an access database into a datagridview, which contains web urls. When button is clicked it webbrowser1 navigates to each url and each webpages document.inertext is put into textbox. This all work fine but after a while the webbrowser navigation becomes increasingly slower.
For Each RW As DataGridViewRow In Me.DataGridView1.SelectedRows '''''''''''#######cell values into strings ########'''''''''''''' If RW.Selected = True Then Dim domain As String
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
