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 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:
<input class="someclass" type="hidden" value="3" name="user_status" />
I just dont understand regex enough to cope with these situations.

I'm trying to extract a portion of html between 2 comments.
here is the test code:
Sub Main()
Dim base_dir As String = "D:"
Dim test_file As String = base_dir & "72.htm"
[Code]....
The HTML file contains the start and end comments and a good amount of HTML in-between. Some content in the HTML file is in Arabic.
This is a follow up to another question of mine. The solution I found worked great for every one of the test cases I threw at it, until a case showed up that eluded me the first time around.My goal is to reformat improperly formatted tag attributes using regex (I know, probably not a fool-proof method as I'm finding out, but bear with me).
My functions:
Public Function ConvertMarkupAttributeQuoteType(ByVal html As String) As String
Dim findTags As String = "</?w+((s+w+(s*=s*(?:"".*?""|'.*?'|[^'"">s]+))?)+s*|s*)/?>"

I have a rendered HTML page that I am exporting to MS Word and downloading on a button click. Here is the code snippet in the button click.
[Code]....
style attribute does not working. In my code i am using an image for print.I want HAND CURSOR, so i added style attribute like the code below
<img id="btnPrint" alt="Print" imagealign="AbsBottom" onclick="winPrint()" src="../../Images/print.gif" style="cursor: hand" />
but this is not working in browsers other than Internet Explorer.
I have made an application in VB.NET.The Button click codes are working fine. I have made a small modification in the code. I have commented the line 'Me.Close'But still my form gets closed. I think the application is executing from elsewhere.

I don't have intellisense when i typ this:<p class="<%= boolean.falsestring %>"></p>
To further clarify (see line below), the first <%=%> doesn't show me intellisense popup, the second however does, why is that? <p class="<%= boolean.falsestring %>"><%= Boolean.FalseString%></p>
I have some update panels on my page that do some asyncpostbacks to keep some dropdownlists correctly populated. My problem is that on my page i have an HTML input that is handling some file uploads. With the AJAX on the page with asyncpostbacks, and while i step through my code behind, the files arent being uploaded. Using a postbacktrigger (non-async) is not possible because of my layout.
Here is my code:
<div id="divFileInputs" runat="server">
<input id="file1" name="fileInput" type="file" runat="server" size="50" style="width: 50em"
onfocus="AddFileInput()" class="textbox" /></div>

When I put a breakpoint in at the declaration of service and then check the value of "files", the count is 0. I am expecting it to be 2 when i have one file uploaded.

I have a big problem with a software I'm creating for my own use.I have code in my software that downloads the source code of a webpage into a .txt file and filters out information it's looking for. For normal HTML code this works fine.The problem is when I can't target specific parameters in the HTML code because they're too vague.I can download this kind of unique HTML code and pass the variable (Brown in this case) to Strings in my software because it's on the same line of code making it unique:
<div class="Performer_DataLabel">Hair Color:</div> Brown</div>
However I want to know how to search a specific table and its rows and cells (like this one below showing the code for 1 row and the 2 cells I'm interested in):

4. </td>
[code]....
The question (Hair Color), regardles of how many hundreds of lines the full source code is, is always on the same line within the row of the table (line 3).The answer is also always on the same line (line 6) in the row of the table.However the question rows themselves are not always on the in the same place of the table.
