I'm trying to create the form which would allow data entry
to the Client table, as well as modification and deletion

fields to the form: I click on Delete or Edit inside of

support this property or method"
If I remove data entry fields from the form - DataGrid

I suddenly received an unexpected error in my project. I have been working
on this project for some time without this issue. Nothing has changed in the
form that caused the exception. A little experimentation shows that I cannot
run ANY .NET web project without getting this error:

What is the easiest way to get the "row object" or "item object" when a
datagrid is clicked?
I have web form with a datagrid. And I have an array of something called
BlogEntry that I bind to the grid like this:
private void Page_Load(object sender, System.EventArgs e)
{
BlogEntry entries = DataLayer.GetAllBlogEntries();
DataGrid1.DataSource = entries;

I am building a simple user control - a listview, a couple buttons. I build
the solution, drop the control on a form, and all is well. I then go back,
modify the Usercontrol, rebuild, and still all is well. However, at some
point I get the "Object Refererence not
set to an instance..." error when I rebuild. If I try to drop the control
on another form I get the same error. I do not believe it is the code in the

I have an app that I've been developing in MS Visual Studio 2005 Pro, C#. I have connectivity to a SQL server database. All of the sudden, whenever I try to add a new or change an existing data binding to a text box (as an example), it gives me the error, "object reference not set to an instance of an object".

Hi -
Please be gentle. I am quite new to visual basic, but I have been
going through tutorials and reading up. I found a code snippet on the
internet that I wanted to see if I could re-purpose for a project, but
I keep getting the error: "Object reference not set to an instance of
an object" for the 7th line of the code below which is:
obj.ConvertPage(URL).Save("C:\screencaptest2.bmp",

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

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,...
