Extract Some Info Of A HTML Source Code And Put It In A Textbox?
Jul 22, 2011
I need to extract some info of a HTML source code and put it in a textbox...i treid a lot of things and even the best idea's crasht what i got this far is :
Private Sub Button2_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button2.Click
WebBrowser1.Document.GetElementById("value_wood").SetAttribute(TextBox3.Text, "class")
End Sub
This may sound really stupid but I have to ask cause I'm not finding this answer anywhere.I have an application where the user will need to sign up for a new user account on the website [URL]..However when I am using Firefox's plug-in Firebug to view html I am getting something totally different than when I just right click on the site and view the page source.
What I am trying to do is to get the captcha from the website and display it in a picturebox on the application so the user can view the captcha, solve the captcha and then the app post is back to the service for a response.
Here is the source that I am getting using Firefox's Firebug to inspect the element:
<td> <input type="hidden" value="Oo3Jo1I8bgzK68agMqo3s79ZZib2OkbK" name="iden"> <img class="capimage" src="/captcha/Oo3Jo1I8bgzK68agMqo3s79ZZib2OkbK.png" alt="i wonder if these things even work"> </td>
[Code]...
Why would the two be showing me two different versions of the HTML?
And how would you be able to grab that source to view in a picturebox using webclient?

I am trying to extract everything between the body part as I am building a forum crawler and since all the user posts are between the <body></body> I have chosen to experiment with Regex. So far I have coded the following but sort of stuck on how to output the result say in a textbox? Also I am not sure if the body part of the regex is correct.
Dim URL As String = Textbox1.Text Dim request As System.Net.HttpWebRequest = System.Net.HttpWebRequest.Create("URL") Dim response As System.Net.HttpWebResponse = request.GetResponse Dim streamReader As System.IO.StreamReader = New System.IO.StreamReader(response.GetResponseStream()) [Code] .....
I have got a problem with the regex pattern. I couldn't be able to extract the id in the images tags from the html source when I find the matches pattern that I selected on the listview items. [code] It have found the matches with the html tags, but it doesn't extract the id from the images tags. [code] Do anyone know how I can extract the id in the images tags from the html source?
what i am trying to do is extract information beween two tags in some html from the source of a website. The contents of the text between the two tags will always be different. the code i currently have is;
Way to space out the source code of a web page, having each tag on one line, without having to search for each tag ending and then making a new line after.
I am trying save a value from an input tag in some HTML source code. The tag looks like so:
<input name="user_status" value="3" />
I have the page source in a variable (pageSourceCode), and need to work out some regex to get the value (3 in this example). I have this so far: [Code] Which works fine most of the time, however this code is used to process source code from multiple sites (that use the same platform), and sometimes there are other attributes included in the input tag, or they are in a different order, eg:
I was told to create a project that requires me to extract information from a created textbox to another. This will happen only when the timer reach every 5s. How do I do this using timer that will allow it to run and automatically record the copy the result to another textbox after every 5s.Thx for helping
How to get source/HTML code of the web page that is shown in WebBrowser1 when I click a button? I would like it to be written in Notepad or eventually in new form..
I'm writing a program in VB.net that gets the source code of a web page with a video on it. it then uses regular expressions to isolate the download link of that video. then it uses "httpwebrequest" and "httpwebresponse" to download the video. my problem arises when certain sites have a page where you have to click continue in order to get to the video page. [URL].. called "The.Matrix.Reloaded.2003.mp4" so i tell my program to get the source code for the url [URL]..but it cant find the video's download link because it's searching for the file in the "continue" page's source code. you can see what i am saying by going to that website above and viewing the source code by right clicking on it. and then click continue and do the same when the video appears and you'll notice that the file is only there in the second one.
So my question is how can i get the source code for the page that the video is playing on and not the page where i have to click continue?

I need to find .MP3 format URLS in a HTML source code.So how could i do that?Lets say i have:
Dim wcClient As New System.Net.WebClient Dim data As System.IO.Stream = wcClient.OpenRead(inbox.ToString) Dim reader As System.IO.StreamReader = New System.IO.StreamReader(data) reader = reader.ReadToEnd() reader.Close()

I'm trying to get the HTML from a frame in a website which is loaded into a WebBrowser in my application.
I have this WebBrowser so that the user can login easily by putting the username and password on the login form of the page so that i can get the HTML code from the protected page.
However, i have to read the frame code while the WebBrowser being on the main page because if i enter the frame, it redirects me to the main page again so there is no way of reading the frame code by entering it.
So i don't know how to read the frame HTML code of a website[url]...

I am trying to get source code from a webpage. Webbrowser control is giving me the required information that I am looking for. But I want to use httpwebrequest but its giving me different source than webbrowser documenttext.

Is there any way to do this? I found this:

I tried with &username=...&password=... in the URL but it didn't work
how to replace the html code numbers with the correct ones? i would show you example of html output, but vbforum automatically converts the characters so no point. i wish the replace all the & #40; (without the space) and so on with their correct replacement eg, ( in this case. also would like a short way to do this as i will be using this multiple times. so basically i would like the source to be exactly as it would if you viewed source in firefox browser, not with all the special chars unformatted like visual studio does.
I'm reading html tags from a webpage using Webbrowser and HtmlElementCollection class. Then I invoke specific members (link, buttons etc.) depending on their attributes.I got stuck at one point. The webpage has many similar images in one place. They can be distinguished only but a version number. I need to get this number somehow to be able to invoke the correct link/image.this is the example of the html code (it looks like that - I only removed personal imformation from it) - lets say I got it already saved in a textbox:
<TR> <TD>My text for label</TD> <TD>my text for description</TD> <TD>27 February 2011 12:12</TD>
[code]....
Now - I'm after the number 197 which appears couple of times in the code.I know what is the 'My text for label', 'my text for description' and 'my username'. Also those 3 links in form of images have always the same structure, apart from the number in question - number 197.How do I extract the 197 number alone ? If I would get it, I would use it to identify the link with ID: "id=snapshot_deploy_cms-company-3" and invoke it.Basically I want to do this:If a TR tag contains 'My text for label' and also contains 'my username', then read the number 197 and... say... save the number into a textbox.
