I have set-up a tab control and have buttons set up to add and remove the tabs.I want to place a text box into all the tabs, so when a new tab is added a text box is already placed inside the tab. I am not sure on how I would do this.
Dim myTabPage0 As New TabPage()
myTabPage0.Text = "Event " & (TabControl1.TabPages.Count + 1)
TabControl1.TabPages.Add(myTabPage0)

I have a RadGrid with a filtercontrol on it. The grid fits the size of the window, but certain views have quite a few columns and when the columns get shrunk down, the filter controls don't resize to fit. Is there any way to set those filter controls to auto fix within the width of the column?

I have a UserControl.ascx which essentially outputs the Name and Email of the user currently logged in (stored in session variables, for the record) at the top of every page on my website. Said control is currently called by Site.Master using <%Html.RenderPartial("UserControl")%>.
It works fine when I log in for the first time and my details are displayed correctly, but when I log out and try to log in again something strange happens...
The Control itself tests the condition Session("auth"), which my controller sets to true upon authenticating a user and which it forces to false when the logout button is pressed. All session variables are cleared upon logging out.
(For the record, my user control used to check Request.IsAuthenticated rather than Session("auth") to determine the current Session State. The same issue arised.)
The problem is that when I try to log in as a different user, instead of showing the new user's information in the header, nothing appears beside Name: and Email: (see code below). I suspect this is because UserControl.ascx is not updating its state.
Ideally, I'd like a solution which would force UserControl to check Session variables every time a page is loaded. Is there a clean way to achieve this?

I have just turned to using VB.net and would like to know why when I load an RTF (with tables in a 9x9 cell format) all appears in a 1x9 format...i.e. instead of loading the tables (some are side by side), they load up in series (below each other).

Is it possible to disable image loading on the webBrowser control? - So that pages load faster. I just want the HTML of the page to work with in my code - I don't wish for the page to be displayed. And I know that using httpwebrequest or webclient would normally be the best option for this kind of thing but I need to browse secure https pages and I don't know if that's possible with anything other than the webBrowser control.

WebBrowser Example.zip IntroductionBecause the WebBrowser control that we use in .NET is a COM control, not all of its uses are straightforward and some of them (even those which seem like they should be easy) require that we dip into our Interop toolbox in order to properly implement them.
A perfect example of this is loading HTML content into the WebBrowser from memory, rather than a file or a URL. Anyone who's ever used the WebBrowser control before is familiar with the Navigate2 method, which tells the control to load content from a URL (or path to a file). Loading HTML content from memory, however, is a rather elusive practice because of the many steps involved in making it work.
MSHTML.HTMLDocumentYou might notice that the WebBrowser control exposes a "document" property. The object returned by this property can be coerced to the type of "mshtml.HTMLDocument" (you must add a reference to MSHTML to your project in order to make this work) as follows:
Code:Dim clsDocument As mshtml.HTMLDocument = CType(WebBrowser.Document, mshtml.HTMLDocument)
(NOTE: You will have to add a reference to the COM library MSHTML to your project to make this compile)
Once we create an instance of HTMLDocument, a whole new world opens up to us, providing all sorts of DOM access to the content of any given Web page.
If we were to create our own HTMLDocument object from memory, we could use the "write" method to write HTML content to the document from a string variable, like this:
Code:'initialize the document object within the HTMLDocument class... clsDocument.close() clsDocument.open("about:blank")
'write the HTML to the document using the MSHTML "write" method... Dim clsHTML() As Object = {sHTML} m_clsDocument.write(clsHTML) clsHTML= Nothing
WebBrowser Control ImplementationUsing the HTMLDocument returned by the "document" property of the WebBrowser control, however, is not as straight-forward. Because of the way that this object is created and initialized in memory (by the COM WebBrowser control), the "write" method fails when called as above. In order to write content to the HTMLDocument exposed by the WebBrowser control, we must first marshal the string value to a memory space that is compatible with COM. Once the string is properly marshalled, the COM interface IPersistStreamInit (implemented by the HTMLDocument class) must be used to pass the value into the object.
Interop DeclarationsIn order to pull all of this off, we must declare several Interop pieces, including an enumeration, a function, and two interfaces. The declarations for these pieces are as follows:

I have a created a user control. This user control I dynamically load on a page inside Telerik Panelbar control. I have done all necessary coding to save the viewstate and load this dynamically created usercontrol every time page loads.On this User control I have a asp panel. By default this panel is invisible. When user clicks a button on this user control panel is made visible. On page load of this user control I populate all the controls on this panel.Everything works fine if I dont load this use control dynamically but when I load this user control dynamically and if I make panel visible by default then only all fields on the panel are populated. But if I make by default invisible and on button click make panel visible none of the text boxes or comboboxes are populated. I populate comboboxes on page load of the userControl but inbetween postbacks all the comboboxes on the user control loose data.[code]...
View 1 RepliesIs it possible to load HTML content into the HTMLDocument object without having to use the WebBrowser control? I have an html file stored locally that I want to parse in order to find out which checkboxes are on and which are off.
All of the examples I've found use the Webrowser. It just seems convoluted to have to use the WebBrowser in order to get to a DOM object.
I have been tasked to do a project, and have been given a list of links from the client - what the Project needs to do is:1 - open google with a specific search phrase - no problem2 - look on that page for any links containing any member of the list of links, if found, invalidate the entry in the list, and auto-click the link, then go back3 - repeat for any other "finds" on that page4 - when done, auto-click on "Next" (no problem) and go back to step 2For now, I am not even attempting to auto-click the found link and go back, I am just listing all found links in a TextBox. The problem I am having is waiting for the next pages to load before looking for a match in the list of links. I tried using webBrowser.DocumentCompletedto set a Boolean - I tried testing WebBrowserReadyState in the DocumentCompleted event ar the code below gives the best results but it is inconsistent, meaning it completely misses some pages that I know have links on them that match.

I am working on an internet cafe program for the desktops. This is how it works, the login files are stored on a ftp server in the form of txt files (E.G. USERNAMEpassword). The files are opened in the background of the program. Then once the login button is clicked, the two text boxes (passwords and username) will combine together and then in the background will look for the username and password as a single line of code.

open a txt file without the open file dialog and to save without the save file dialog.
P.S. I'm using a textbox.
I would like to know how to loop with textboxs. For example. I would set the text to "Hello" And the loop will send this...
-"Hello1"
-"Hello2"
-"Hello3"
I have tried many looping techniques but they all used listboxs and even modifying them I could not get it to work correctly.
