I have read the following article
http://www.4guysfromrolla.com/webtech/073101-1.shtml. I added the empty
selection as the first option. When I click submit without choosing
anything it does not return my empty string but the 2nd value in listbox.
When the page reloads it selects the 2nd option by default even thou my
Empty field is in the list. What do I have to do to get the empty field and
databound data to act as one?

I'm using VS2005 and am working with a ASP.NET 2.0 web site and I'm coding
in VB.NET.
I understand that I can add an item to a databound dropdownlist and make it
the default selection using the following code:
MyDropDownList.Items.Insert(0, "My default item")
MyDropDownList.SelectedIndex = 0
The problem that I am experiencing is *where* to put the above code! If I

I have a databound dropdown in my page. I want to make one of the
values the default value. Any ideas?
Just to explain further, I have also appended one item to the dropdown,
using the AppendDataBoundItems="True" property of the dropdown.
Unfortunately the item I have appended to the dropdown has become the
default value of the dropdown list which is not what I want.
Kind regards,

is DBNull what can I do to make the default value be the return value of
this function ( or I want the Id be generated by default in the DataSet)?

I have a windows client database management application written in C# that connects to remote web services to do all the heavy work. The thin-client app uses strong typed datasets, all maintained at the web service, with a web reference to those datasets via exposed s on the web service.
The client app has a series of windows forms designed to manage particular types of data. For example, there's a manage users form. On each of these...

Hi all,
I'm having an issue that's driving me crazy. I have a datatable that I
need to display all the information for on a page. So, instead of manually
coding every single column to a label, I decided it would be easier and
safer to use a formview to display it all, bound to an objectdatasource.
Sounds simple enough. The problem is that many of my fields could
potentially have null values, which produces an error similar to the...

Hi I am using these: ASP.Net 2.0, VB.Net, Visual Studio 2005, SQL Server 2005, Formview controls
In a ASP.Net form I have 20 textboxes and 20 dropdownlists(ddl). All ddl(s) are databound and get the data from a single objectdatasource. All textboxes and ddl(s) support null values. Textboxes are for entering numbers and ddl(s) are for selecting the unit (mm, cm, in, m3, oz, qt like these.).
I am using the below code to achieve two...

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:
g++-12 -std=c++20 -Wnarrowing bit_field.cpp
Here is the code in...

Overview:
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,...
