I have a webbrowser control on a form and try to navigate to one specific site. It seems to me that the remote detects that call is from a desktop program and redirect it. Is it possible? and if it is how I can hide it.

View 6 RepliesIve got an app that holds a list of site we have, At each site there are a few devices. The idea is when they click on a site all the details for the site are loaded and then a second thread sits and pings each device to see if its live. Im trying to do this in a seperate thread so if they click another site while its still pinging them it doesn't wait before it switches site. This all seems to be workling fine except if you click through the sites quickly, when you do that it will eventually come up with
Quote:
{"Collection was modified; enumeration operation might not execute."}
The error flags up on the "Next" line in "ThreadedPing"
Thread stuff
Public Sub ThreadedPing(ByVal dt As DataTable)
Try
Dim dr As DataRow

View 3 RepliesI have been trying to find a way to extract information from a website WITHOUT a webbrowser control. I do not want to use the webbrowser because it is too laggy.
so this is what i've tried:
Dim browser As System.Net.WebClient = New System.Net.WebClient
browser.BaseAddress = ("website here")
Dim info As String = browser.DownloadString(browser.BaseAddress)
[Code]....
as you can see, what i've tried is to download the websites source code then find with an index value the information i want. However, how do i get specific information from the website without having to find the information by its index location?
In short, is it possible to use GetElementById without having to use webbrowser1?
how can i get the html code via WebBrowser control?

What I'm trying to do is when a user clicks button1, i want the program to look through the webpage and check if there is an image source equal to a static URL that I assign. this is basically just navigating to a website & checking if a certain link exists.
View 10 RepliesIn my program I am trying to make a combobox that when the user hits enter it will navigate the web browser to the site address that the user entered into the combobox. I tried this code:
If Keys.Enter Then
WebBrowser1.Navigate(ComboBox1.Text)
And then when I debugged the program and tried it out, the web browser did nothing.
We've been set a task to build a really basic web browser with one advanced function. I've done the web browser with the basic functionality. The advanced feature is a "most visited site" feature. I need to create some kind of listbox, that keeps track of all the websites visited (when the go button is pressed) and arranges them in the most popular order (i.e. the one that has been clicked the most). Furthermore, it states that substrings should be used so that for example if you go to [URL] and go to [URL] that counts as 1 hit. I'm sure its something to do with arrays, but he did say you will need to use multiple procedures/strings/functions....

I am using an embedded webbrowser control to access a third-party website, populate the username and password boxes on their front page, and login. The problem I have is that the resulting window that the site returns to me is in the form of a new window. What I want to do is capture this window and all it's session/cookie data in to the original webbrowser control, as even if I direct the original window to the same resulting url, some kind of authentication data is missing and the site tells me I have logged out, even though the popup window works fine. I need that page in the original control so that I can continue to access it programmatically, and I don't really want to get in to the complication of accessing the new window, as I expect I'll have to delve in to the api or something.
View 1 RepliesI am trying to use my web browser control to get retrieve date from a specific page, including all sub-page content. Problem is some of the sub-pages are on a separate domain and thus I am getting a permission deigned error when i try to access the frame [through document.windows.frames(i).document].Is there any work around to do this, even if I have to manually change security settings? I tried turning all my settings in IE to allow and still same error. I will only be running the app locally and no one will be browsing on IE so I can literally change anything needed to get this to work (even install older version of IE which may allow it but can still handle JS processing).
Note the reason I am using web browser is a great majority of data I will be accessing is JS generated, so I need to access the DOM after JS processed / generated the HTML. Because of this, simply using SOCKETS to get the HTML is really not an option. Even if I had the HTML, I still need some type of engine to process all of the DOM elements based off javascript.

View 2 RepliesI'm using a custom webbrowser to display a special intranet for my company.I need to be able to display a custom keyboard whenever the user can type in the webbrowser. So if they click on a textbox within the page to type, this custom keyboard appears.when the user is in 'typing mode'. I thought maybe checking when the cursor changes to 'ibeam' which is the typing cursor? How might I do that, or is there an easier way?

View 2 RepliesI have an application that loads a web page then allows the user to edit that page by setting the Webbrowser control to EditMode.What I am trying, so far unsuccessfully, to do is trap when a user right clicks on a link already on the web page. The problem I have is that although I can trap the right click using MouseDown and GetElementFromPoint, if the link that is clicked is nested within a higher level element then the higher level element is returned by GetElementFromPoint not the nested element.[code]When the user right clicks, say, the link with test2.html my current code returns the DIV element not the A element. How can I understand which of the A elements the user clicked.[code]
View 3 RepliesI've been trying to make a app that logs into a website. So far it didn't work for me.I have trouble because:
- The "pin" (username) box on the site doesn't have an ID. (Can't use getelementbyid)
- The picture doesn't have an ID either
Codes I've tried:
With WebBrowser1.Document
.All("pin").InnerText = "mypinhere"
End With
End Sub
This should have, in my opinion, filled in the textbox. Now I need to click the login button?Also I found this in the source of the site:
<img src="/media/img/text_AccountPin.gif" alt="Account Pin" width="93" height="10" border="0"> <input type="text" name="pin" class="form" size="15"> </p>
As we can see, it says
name="pin"
So I should be able to use "getelementbytagname" right?Also, the formId is logmein (log me in)
<form id="logmein"....
This is what I came up with:
Dim webbrowserDocForm As HtmlElementCollection = WebBrowser1.document.GetElementsByTagName("logmein")
For Each curElement As HtmlElement In webbrowserDocForm
Dim controlValue As String = curElement.GetAttribute("Value").ToString
[code]....
in the next code it's tagname is "input" or "text"? Because I found:
<input type="text" name="pin" class="form" size="15"> </p>
Code for filling in:
webbrowserDocForm = WebBrowser1.document.GetElementsByTagName("text")
For Each curElement As HtmlElement In webbrowserDocForm
Dim controlName As String = curElement.GetAttribute("name").ToString
[code]....
It doesn't give me any errors no more, but it doesn't work either.
I am not sure if this is possiable but I am looking to build an application that will login to a web site, navigate the site and download files.

View 16 RepliesI'm deploying a VB.Net app (VS 2010 Pro) that requiers the user click a command button to open IE to a financial WEB site and download informaion from the site. The app works fine in every detail when installed on the development computer. But, on the target computer when the command button is clicked an unhandled exception occurs which says: System.IO. FileNotFoundException:File Not found.My code behind the button is Shell("C:Program Files (x86)Internet Exploreriexplore.exe www,fidelity.com",AppWinStyle.NormalFocus)
This works fine on the development computer. Do I need a way to code this as a relative path? If so,can you tell me how this is done?Throughout the app I have written relative paths to needed files using paths like (Open(Environment. GEtFolderPath (Environment. SpecialFoldder.Desktop) + "File Name). They all work fine when deployed.
I'm being asked to maintain several internal-only web apps for my company. For testing, after making my changes, I've created some staging sites which make use of separate databases. As such, if my users were to mistakenly use this site as if it were the production site, they may enter important data and wonder where it "disappeared" to thinking it was the production server.
I'd like to create a big banner of some sort across the top of the staging site (which ONLY appears on the staging site) to remind my users that they are on the test site. I'd like recommendations on the best way to do this, with the following considerations:
IDE: Visual Studio 2008
Server: Windows 2003 with IIS 6
Language: VB.NET 2.0
