Website Is Visible When Page Is Rendered In A Webbrowser Control
Feb 17, 2009
I am trying to figure out if the text from a website is visible when the page is rendered in a webbrowser control. The text I am looking for is error text that shows form field errors after a bad post submission. I've checked the source code of the html being returned and the actual html for the text i'm looking for is present before any errors are made, and after the errors are detected. is there any way i can do a sort of .visible check on html elements in a webbrowser object, or even check the css that is linked to a particular div/label/span for the visibility/display style tags?
I am trying to delete a customer record. In the page I have an usercontrol for address and it has some validation. I cannot delete the record since it fires the validation controls.
i know how to draw a rectangle and fill it but how do i make it visible over a WebBrowser control, also how would i make the FillRectangle 60% transparent? i have found no understandable results on google. could someone please help me figure this out?
Private Sub Button2_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button2.Click Dim myGraphics As Graphics Dim MyBrush As New SolidBrush(Color.FromArgb(128, 0, 0, 255)) myGraphics = Graphics.FromHwnd(TextBox1.Text) myGraphics.FillRectangle(MyBrush, New Rectangle(0, 0, 100, 100)) End Sub
I have been trying to use the WebBrowser control to access a website, nothing fancy involved, just a Security Certificate error message I can't get around:
The site that I've been trying to access is [URL].. By clicking on the "Login" hyperlink you are taken to a https connection.Internet Explorer simply allows you to click on the "Continue to this website (not recommended)" link which displays the Logon screen.Clicking on the same link in a WebBrowser control simply reloads the page as (I assume) WebBrowser has not been told that the page is ok.
I've tried looking around for the solution with no luck, it seems like such a simple problem..
I have five menu items that i have created as a user control and placed on the master page. Now i want one of the menu items to be visible only for particular user role and not visible for others. Here is what I did. Its not working though.
I need to get the page source of a website using a proxy without using any ocx control and as much as possible without using a web browser to make it more difficult When i get the source i need to fill a textbox and press a button. After i get the response as html.how to do this because i found alot of topics in this forum especially kelimna's.
I have a website that divided into 4 frames. I'm trying to create an application that will constantly run on my PC as a task looking for certain text in the HTML in a frame.When it finds the text it would alert the user by presenting a pop-up message. This is basically a monitoring website that checking network nodes. Instead of staring at the screen looking for critical messages I would like to be notified when there is an alert.
I have made an app that will check to see if a website is on the 1st, 2nd, 3rd, 4th, and 5th page of google, the websites are in a datagridview. I am using five webbrowser controls but it begins to get slower and slower? As it searches for each website using a for statement. How to improve this code to make it run quicker, or even a better way to go about it.
I'm trying to access a secured website using vb 2005 and webbrowser control. I've got the credentials, the script can pass the login page but when trying to navigate to the second page within, the page is being redirected back(to the first page after logging in). The second page I'm trying to get to retrieves the data from a database and displays some options for the user to select in order to prepare a report which can be downloaded after the fields selections. And I wanted my script to do this automatically without user interaction.

I am trying to automate login and navigation to a website using the WebBrowser control. I can successfully logon to the site using the wb control but after that I can't seem to get access to the newly loaded document's elements within the same routine. I check for ReadyState Complete and IsBusy but they don't seem to be working. There don't appear to be any frames being used at all so I can't figure out why this won't work. I know that the wb control is successfully logging in because I can see the page load in the wb control. However, after the page loads I try to access the HTMLDocument for the new page (after logging in) and it is either set to Nothing or it's the previous page's HTML. I've tried putting in a Sleep to wait for the page to finish before trying to access the HTMLDocument on the new page but it still doesn't work. If I create a button on my form that accesses the HTMLDocument and click it it works fine. I can't figure out how to ensure that the entire page has finished loading within my routine. I tried putting a switch into the DocumentCompleted event but that doesn't work either.
I need my application to go to a website, press a button on the website to get data, and then get the data that it shows all without the user seeing the webbrowser control. I'm doing this for a little project. The user could normally just go to the site and press the button themselves, but that would take to long. So how do you programmatically do this?
I know it is possible to save a page viaWebBrowser1.DocumentTextI want to save the current loaded page in webbrowser controlin the same way i.e. does,creating the mypage.html and the associate dir mypage_filesthis way I also save images
I am using a WebBrowser-Control to fill in a webform and then click at a button, this currently results in a standard Download File Dialog (you get these if you download a file using internet explorer), but instead, I have to catch this file and save it automatically with a by me defined name to a specific folder.I am trying to code a little application in vb.net which download the Export-file from my wordpress-blog, and I want to do this completely without user-interaction.Currently everything works, except the downloading of the file.I tried to catch it with the event System.Windows.Controls.WebBrowser.Navigating(ByVal Object, ByVal System.Windows.Navigation.NavigatingCancelEventArgs) but I don't see where to download the file from?
I have a web browser control, what I use is: Ret = (MainBrowser.ReadyState <> WebBrowserReadyState.Complete Or MainBrowser.IsBusy) If ret is true, not loaded, otherwise, loaded. It works fine on winxp, however, on vista, most times, it works, sometimes, not. Do I have to use documentcomplete for this? The page is loaded from another thread, does it matter?
I'm using a webbrowser control in my program and I navigate to a page that uses sessions. I need to delete them somehow and I tried to close IE and enter it again and it worked, the sessions were deleted. But I've done it manually, and I need to do it through my program, so is there a way to imitate the closing and reopening of my webbrowser control?
I am navigating to a web page with my webbrowser control
[Code]...
and this works on most pages. Now I'm going to a page that I guess there are errors in the page and I get a box asking me if I want to debut in IE's built in script debugger or something to that effect. Is there any way to have the system ignore this message and continue to load the page as normal

Hi,I need to see if a webpage displayed via the web browser control contains certain words .I've tried parasing through the html but that contains too much junk html and css tags which caused problems(I've tried using regex to remove them).That was done by using property webBrowser.document.Body.InnerText.contains .
Are any way to search through the actual text on the webbrowser and not html via the program in ways similar control-f function on most webbrowser but using code to do that ?
I am using web browser control in one of my forms for displaying html files (local files). Before I load the next file I want to clear the webbrowser control of the previous page. I am trying the following method which I found while searching the net.
private Sub ClearWebBrowser(ByVal wb As WebBrowser) Dim tempDoc As IHTMLDocument2 = CType(wb.Document.DomDocument, IHTMLDocument2) tempDoc.write("") tempDoc.close() End Sub
I have added the reference for mshtml namespace in com tab. When trying to run the program, error is thrown like "Type 'IHTMLDocument2' is not defined. (BC30002)".
I'm using a WebBrowser control in my current program in a bit of a bastardized way: I don't use it visually, I just use it because I'm more familiar with its events.
So, basically, I create a WebBrowser control and navigate to a page to login. Then, when logged in, I create a new WebBrowser control and navigate to a different page.
I've used this program for four months with no difficulty. Starting today, though, the second phase of that has been going really, really slowly. What used to take 3-5 seconds is taking 25-30 seconds. It still works eventually, it just takes a while.
Usually I would assume this was a server problem. However, navigating to the exact same URL in Firefox happens extremely quickly. Weirder still, within the program there is a user WebBrowser control -- I can copy/paste the URL the previous (not visible) WebBrowser was navigating toward into this user WebBrowser, and it goes just fine.
What in the world could be holding up this other "custom" WebBrowser? I don't even know where to begin in diagnosing this.It might be important to note that the site this is working based off recently underwent some changes -- but I can't imagine why that would affect only these "custom" WebBrowsers and not the user one in the same program.
I have been tasked to do a project, and have been given a list of links from the client - what the Project needs to do is:1 - open google with a specific search phrase - no problem2 - look on that page for any links containing any member of the list of links, if found, invalidate the entry in the list, and auto-click the link, then go back3 - repeat for any other "finds" on that page4 - when done, auto-click on "Next" (no problem) and go back to step 2For now, I am not even attempting to auto-click the found link and go back, I am just listing all found links in a TextBox. The problem I am having is waiting for the next pages to load before looking for a match in the list of links. I tried using webBrowser.DocumentCompletedto set a Boolean - I tried testing WebBrowserReadyState in the DocumentCompleted event ar the code below gives the best results but it is inconsistent, meaning it completely misses some pages that I know have links on them that match.
I am using a Webbrowser control to access the elements in an HTML page which contains a JavaScript link which when clicked, adds extra content to the page. This works fine in IE 7 and Firefox.I then want to access this extra content in my program. Having found the HTML element containing the link, I tried element.InvokeMember("click"). I have used this successfully with a submit-type link to login to the web site, but cannot get it to work with the JavaScript link. I also tried setting the focus to the link element and using SendKeys to send the ENTER key, but all to no avail. Nothing seems to happen. I don't see the extra content produced by the JavaScript, nor do I get an error.Here is an extract from the HTML, showing the relevant (I hope) code:
