How do i hide an html img from a code behind file in VB.NET? The img tag doesnt have a runat attribute and hence not a server control. I tried
Dim cs As ClientScriptManager = Page.ClientScript
cs.RegisterStartupScript(Me.GetType(), "alert", "alert('test')")
in the Page_Load(). But doest work. I want to access the id using javascript (document.getElementbyId('idofimg').style.visibility = 'hidden')
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 enrolled in a class in Visual Basic 2008. I wanted to drop the class, but it is too late. Now, I am stuck with this project that the professor assigned and it's due this Thursday. Anyway, how do I do this: The credit card number TextBox control is dynamically enabled/disabled depending on the choice of payment type? And did I do the newOrderButton correctly (see code below)? This is also the clear button. And is there a way to do a reset Form? Sorry for that many questions. I am really lost right now because there is a lot to do in this project and I don't even have a clue of how I am going to finish this project.

If I try it with out the @, I get an empty white page. If I change the address, however ,so I know its a broken URL, I get a 404 message, which makes it seem like it's finding the file but not rendering it?The second method does the same as the first except no error is produced, its like its finding the text but doing nothing.

I have a For Each loop going through the controls in a panel disabling them. When the loop reaches one certain grid control and disables it the CheckedChanged event fires for the next control in the loop which is a radio button.
The call stack is as follows:

System.Windows.Forms.dll!System.Windows.Forms.RadioButton.WnProc(Microsoft.AGL.Forms.WM wm = WM_RADIOBUTTON_NOTIFYVALUECHANGED, int wParam = 0, int lParam = 0) + 0x17 bytes

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.
atm i have this If TreeView1.SelectedNode.Name = 2 Then WebBrowser1.Url = My.Resources.Welcome End If
and it doesn't work so if you could please provide an example that world be grate.Also i don't really know how the treeview control works, i know with the combo box or listbox you just have an index of 0, 1, 2, 3 etc. but with the treeview you don't any just one of the things i want to do is whenever the root node is selected i want it to deselect that and select the node that i specify like node.name = 2.

I have successfully ported a VB6 application to VB.NET (VS2008, .NET 2.0). Much optimization and rewriting has been done, but there is one possible BUG i cannot overcome. I have a standard HSCROLLBAR control used for accepting a numeric input. The control needs to be disabled during complex computational routines to prevent additional user input. I am setting the enabled property to false and reenabling the control at the end of the calculation cycle. The control is enabled and disabled a few times, because some code has been placed in the onpaint event of a drawing area, and separating the calculation part from the drawing part will be a huge task.
Large changes are handled correctly. Small changes aren't. The problem is that the control freezes in a unknown state after clicking on the arrows. A second click makes the control (and its parent control box) jump up and over everything else in their container.The scrollbar remains functional only via the contextual menu. This happens both in debug and release builds. There are no overrides. Coding/Test platform XP SP3 (more than 1 machine).
There is no code whatsoever that handles neither the parent control nor the scrollbar repositioning and resizing. The only code takes the value of the scrollbar and passes to the calculation section. If I omit disabling and reenabling the control, everything works fine.i tried rebuilding the control from scratch. forcing enabling the control after it has gone haywire does not make changes, disabling the groupbox instead of the single control doesn't make any difference, debugging step by step confirms that things go wrong when drawing the controls within the private system form classes.

But although this works, it does not execute my VB code in the code behind page so I am a little confused where to go here.
A recent project of mine has been to make a designer. I've finished everything, but when I click the controls to show the properties window, the control interacts with the cursor. So my question is: How do I freeze the controls from interacting with clicking or key presses without disabling the control itself?
