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 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 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.
View 1 RepliesI'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.
Public Class Form1
Private Sub TestButton_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles TestButton.Click

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.
View 2 RepliesI 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?
View 8 RepliesI 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?
View 2 RepliesI 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?

View 6 RepliesI am working on some project where I suppose to pull data from internet and print them out. Thing is I need to go to several different websites, so I want to make application that will go to websites declared in code and on those websites type into textbox word that I want and hit search. Once I do that I will easily use regular expressions to get information I need, but I need VB.NET application to do this. Example: I have button and textbox in my application. In textbox I write "VB.NET", once I hit button application will go to google.com and in search textbox type "VB.NET" and hit search and then I will pull data using regex into my application.
View 2 RepliesI am currently trying to develop a program, for personal use, that will monitor the lending of items of music equipments to friends and family etc. And, for my program, I have a requirement, which is the ability to search a relational database, for items loaned, through my program, based on criteria entered in a set of text boxes located upon the program's form. I have already set up the form, and have searched the Internet high and low, to no avail (probably didn't look hard enough).e,I would also like to make another request... if possible I would like to achieve this task with use of the 'LIKE' statement, so that I don't have to input the criteria in full, when I wish to search the database.
The database that I am using is a standard Microsoft Office Access database, saved in a '.mdf' format, and the database comprises of three tables; LoanTbl (which specifies the loan details), EquipTbl (which contains information about the equipment loaned) and a LinkTbl (which forms the relationship between these former two tables) - the reason for the LinkTbl, even though it may seem unnecessary, is because the data has undergone 'normalisation', so that it is stored in the most efficient way possible.
Also, whilst I am on the point of linking together my program and database, does anyone also possibly have any ideas as to ways in which to add data to this relational database; I do have coding for this, however, it only applies to a stand-alone table, whereas there are relationships between my tables.
What is the best way to search in the text in webbrowser?
View 2 RepliesIs there a simple method to tell whether a certain word is present in the webbrowser (not the source, but the visual stuff).
I can't use the source because it takes too much time to load when it's a rather large site page. And I believe I can't use instr on webbrowser1.HtmlDocument.
Who can point me in the right direction, I didn't find any solution myself with google. I only need to know if for example the word 'New' is present on this page, so a True or False must be returned

View 1 Repliesrecently I've been going through some website login automation and ended up with creating a simple my own browser quite happily, to open websites and login straight away.
But I found out that I can't automate some of the websites I was going for, because the html code of the login forms is not shared and cannot be seen in the source.So I'll give you guys a couple of websites I can't deal with and please advice if it is possible to do stuff with them:[URL]...

View 1 Repliesi have seen google chrome, whenever you open a new tab, it will show you the last 8 pages that you have visited. I want to do a similar thing, except i have a vb.net code behind the .aspx file, which shall give me a list of URL's called form the database. When the page is loaded the URL's are displayed on it. what i need my code to do is to pick up these URL's, on the background open a web browser, take a snapshot of it and save it, and display it on the screen. dont recommend IFrames cause I need a snapshot and not an actual running site in the small snapshot.

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.

Im currently working on a project which included a webbrowser navigating to a website. Whenever it arrives there it disables me to double click on the Media Player inside the website to go full screen. Although I know this is possible as Ive seen that the webbrowser can disable clicking on Firefox. My question: is it possible to enable the standard webbrowser in Vb.Net to allow me clicking even if the website doesnt.
View 2 RepliesI've got a webbrowser. It's prettey advanced, given that I've spent quite a lot of time coding it, and here is my code which will get the Favicon of the current website when a the webbrowser has finished navigating:
frmBrowser.BrowserTabs.SelectedTab.Icon = Controller.GetFavicon(Me.Url.Host & "/favicon.ico")
Sometimes, a user has switched tabs before the webbrowser has finished navigating. So my question is: Is there any way in which I can determine what tab the favicon belongs to and set it to that tab, rather than just setting the favicon to the selected tab?
Is there a way to make your webbrowser connect (or your computer ping) to a website via proxy server? (ex: 123.123.123.123 :: 12345)
Not a proxy like corpask, but an IP and port.
I have programmed a web browser with Visual Basic 2010 Express and came across a major bug. Whenever I try to click a checkbox on a certain website, this error message appears:
An error has occurred in the script on this page.
Line: 193
Char: 9
Code: 0
URL: [URL]
Do you want to continue running scripts on this page?
[Yes] [No]
After clicking yes or no it just pops up again and I have to open the Task Manager just to close the browser.
My code requires the webbrowser to be up so I can sendkeys something onto a website form. For some reason, changing the attribute doesn't work with this website. When I'm doing other task, such as web browsing or something else, the following code works occassionally.
AppActivate("xyz")
WebBrowser1.Focus()
Is it possible to sendkeys to a website form in the background? This would be the ideal solution. What other command do I need to consistently pull up my application into the foreground?
