In my previous posting I failed miserably, to give enough information to get
my difficulty apparent.
So to start again. I want to create textboxes dynamically in VB.NET. This
is not a web application that I'm trying to build. I should add that i am a
very new user to VB.NET and as such am very ignorant so please excuse this.
Many thanks for any assistance.

I'm working on administration panel that will ultimately allow the
client to edit products in a collection. Each ProjectList can have
multiple products within it. I was asked to create something that will
allow them to edit the products within that list. I was thinking of
writing using a DataReader and spitting the values out into textboxes.
The only problem is that I won't know beforehand what the textboxes
would be called. In the past...

I've built a WebForm with a Table added dynamically in Page_Load when
IsPostBack is false. The table includes a couple of TextBoxes,
RadioButtonLists and CheckboxLists.
On postback, those controls are not present nor their valves in
Request.Form.AllKeys.

Okay, here's my problem:
I need to populate different fields in an HTML table with TextBoxes. For
example, if I had 3 columns "Name", "Address", and "City"; I need to have a
TextBox in all of the Address fields. This is basically the code that I used.
<script language="VB" runat="server">
Sub Page_Load(Sender As Object, E As EventArgs)
Label1.Text &= "<td align=left><input type=""text"" id=""txt"
& _

hi all,
how can I populate one aspx form when page is loading based on page ID? for
example:
loading page A (to search for VB code) would display labels and texboxes,
dropdown lists all related to VB, plus the address bar would show something
like this: www.somethinghere?id=3
and if you change number 3 from the address bar to (for example) 34 or 71
you would get different page with the same formatting like I.e:
www.somethinghere?id=34...

Hello
In VS2005:
I am adding buttons and textboxes dynamically into a table, that also
dynamically expands.
So far, so good, actually very nice.
But I am having trouble starting the desired subroutine on postback. To me
it seems like the button click event looks for a client script instead of
going to the aspx codepage and execute the sub there.
The same thing happens with textboxes, where I programatically add

I have a page with mixture of static and dynamically added controls is there
any way of controlling the order which they are added to the page. My submit
button (statically added) appears before some textboxes (dynamically added).
I know I could move it around with CSS but I want to move towards an
accessible site that will display forms in the right order without CSS.
Regards, Chris.

Hello folks,
I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
This is as boiled down as I can make it.
Here is my compilation command:

Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows. In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not. For most users, this new feature is actually very convenient. If you want to control the update process,...
