VS 2008 WebBrowsers - How To Get Data From Two Tags
Jun 24, 2009
I've crafted together a quick web page together to look something like this:
<span class="vanity">Just A Test Document</span>
<br>
<B>Hey VBForums!</B>
I have a standard text box, a button & web browser control on my form. On the load event I send my browser out to this web page. I had a quick question, after clicking button 1, does someone know how I could get the data from in between these 2 tags '<span class="vanity">' & '</span>' into Text Box 1?
I'm trying to analyze web pages for seo. I'm trying to create my own personal tool to extract all the keywords and tags from web pages (a little clearer).I already know how to extract or parse links and text from web pages. The issue is that I tried to implement title tags, body tags or keyword tags in general via using the following code:
Dim theElementCollection As HtmlElementCollection = WebBrowser1.Document.GetElementsByTagName("a") For Each curElement As HtmlElement In theElementCollection If curElement.GetAttribute("href").Contains("http://twitter.com/") Then
[code]....
Try to extract all the keywords from the title, body etc. for this page:[URL] and send it to separate textboxes (title keywords in textbox1, meta tags in textbox2 etc.).
I was just wondering how to extract or parse any particual tags (whichever I specify) from webpages. I know how to extract text and links from webpages, but I tried to use the same method from the following code for div tags, title tags etcetera and it doesn't seem to work:

i'm trying to get the following data from within the html tages <td class="colRight">CWCH60</td> where CWCH60 is the data which changes and needs to be extracted. I have tried the following Regex patterns
I am planning to create a system for my case study wherein i can Add tags from images and search for it by "tags" such as photobucket. For example i open an image to my system, and it's file name was "WhiteHouse.jpg" and i added or tagged it as "Building". Once i search on my computer, and type the word/keyword "Building", the image "WhiteHouse.jpg" will be displayed on search results as i tagged it on my system.Is that possible guys? or i can only search by tags using my system/application? and not in the search command in my computer?If it is possible please tell me what to do. or if you have sample vb.net2008(windows Application) files it will be helpful. Or if you have sites related into it. pls send me those links, especially downloadable vb.net files w/ codes for further studying.
i m working on the project like retrieving the data from the tally using our vb application and store the data in database. i have fetched the xml tags from my vb application to the tally by sql query. now my question is how to extract the data stored in between the tags using vb,.. and store in database.. i need the procedure and the code.
My problem is I used to be able to do this,[URL]..and CallAFunctionThatReturnsBoolean() will be called in Page_Load when the control's DataBind function gets called implicitly and the div's visibility will be set correctly.
Now for some reason this doesn't happen anymore, and to make it work I would have to either call Page.DataBind() in my base Page class or Me.DataBind() in the Page_Load sub in that page, but I don't really want to do this, especially in the base Page class because then if I have a page with let's say a DataGrid in it that I already call the DataBind() function explicitly, then this DataGrid will get bound twice, once from Page.DateBind and once from the explicit call datagrid.DataBind().
I Want to have a WebBrowser1 and WebBrowser2 on the same form and be able to login to WebBrowser1 with account1 and login to WebBrowser2 with account2.
basically i want it so if a message box pops up, with the "Yes, No" buttons, i want it so if you press "Yes" the Web Browser will Redirect to a specific Website.
If MsgBox(vbYesNo) = vbYes Then WebBrowser1.url = "Adress Here"
I am using the webbrowser control so I can create articles in VB.NET and save the data to a database with the correct html tags, allowing the data to be seen on a dynamic website. I have create a little menu bar with buttons on for bold, italics, etc. The problem is I have two webbrowser controls on and if I click on the first webbrowser I set in the gotfocus a flag which I use in the click events for bold. This means it knows which webbrowser to do the bold on. The problem is, first time round when I click on the first webbrowser it does not call the gotfocus event.
I was looking through the internet for codes for word search and the onlyone i found was for non-tabbed webbrowsers.I've been fiddling with it but i cant figure out how to change it for Tabbed Browsers.
I am developing an app that has a treeview on the left in panel1 of a split container. When you click in a node it loads a user control into a tabcontrol that is in panel2. Some of the user contols contain webbrowsers that autorefresh every 15 sec (not under my control). I can successfully remove a tab by a contextmenu but I can still hear the clicking sound of the webbrowsers refreshing. Not sure what to do to completely remove the usercontrol. Treeview control code for one node: there rest are basically the same
Code: Dim tabcount As Integer tabcount = TabControlMain.TabCount
[CODE]...
Code to remove a tab and all tabs:
Code: Private Sub RemoveToolStripMenuItem_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles RemoveToolStripMenuItem.Click TabControlMain.Controls.Remove(TabControlMain.SelectedTab)
[CODE]...
I also originally had this setup to work without the tabcontrol and just load the usercontrol into panel2 of the split container. Each time a new node was selected from the treeview I would have SplitContainer1.Panel2.Controls.Clear() to remove the current usercontrol. I would still hear the clicking of the old usercontrol.
I am trying to figure out how to get the "1:39" from this page's source:
[Code]....
I have searched the forums through pretty well, and cannot find a solution. I am assuming I would have to use Regex to get the numbers specified. If I need to provide more of the page source,
I am trying to format xml entries I have so that I can use the xmltextreader without getting errors. I added a default header and footer in the event I notice there is no opening or closing tags. I remove illegal characters and check for unicode but I always find an issue where an entry slips in and gives the error: data at the root level is invalid and when I check that entry is slipped through the cleaning process or just has an unmatched tag somewhere.
Now I use Dim stringSplitter() As String = {"</entry>"} ' split the file content based on the closing entry tag sampleResults = _html.Split(stringSplitter, StringSplitOptions.RemoveEmptyEntries) To split my xml into individual entries before I start the cleanup process.
Here are my default headers: Private defaultheader = "xmlns=""[URL]""" Private headerl As String = "<?xml version=""1.0"" encoding=""utf-8""?>" & vbNewLine & "<entry " & defaultNameSpace & ">" Private footer As String = "</entry>"
Is there any tool in the .net framework that can detect and cleanup unmatched tags so that I can get this to work.
i have text in textbox1.text How can i wrap html tags around that text by clicking a button. Example : Textbox1.text has "Hello there" in it When i click a button i want it to display :
This is the format of the html, i just need to gett he users age and name, using reg ex i have so far:
Dim proxySourceHTML As New Regex("(?<=<tr bgcolor=""#ffffff"" class=""text"" height=10>"").*?(?="".*?"">)", RegexOptions.IgnoreCase Or RegexOptions.Singleline) Dim matchesFound As MatchCollection = SourceHTML.Matches(GETHTMLResponse)
Did anyone already try to read RFID tags but not by reading request?I mean, When some tag is readable can't just the RFID reader detect it?So far this is the code I've been trying to use without success.

When in VS 2008 if a developer hits the ''' it generates the XML comment tags for you, but this only works when the project setting for "Generate XML documentation file" is checked. Is there a way to tell VS to generate the XML Comment tags, regardless of the project setting? I think it is possible that someone may want comments but not create a XML documentation file. In this case I am exceeding the current Team Settings, yet other developers don't want me to change this project setting. This forces me to flip this back before checking in the project. I have the same problem with other Project settings like "code Analysis". This is only a problem for VB.NET projects.
