I've got a simple windows form with some bound textboxes
and Save button. Each texbox is bound to column in a table
in an Access database. The form fills fine - all the
fields show the correct data for the record I load. So
then I change the contents of one of the textboxes and
click on the Save button. The button's event handler then
calls the data adapter's Update method and I check the
return value. Nada-zilch-nothing. I even put a...

HI,
I am trying to update a DataGrid where I want to rebind just the row that
was updated.
Here's the situation:
1) Updating is not a problem, it works fine.
2) I am not using ItemCommand (edit, delete, etc)
3) the button that issues the update/rebind is outside the datagrid, on the
web form.
Till now I have been issuing a full DataBind for the entire DG, that I read

Hi guys,
I've been trying to implement an editable datagrid and i have been
succesful up to the point where i can update my datagrid row by row.
However what used to happen was that once i updated one row, all of
them were updated so i immediatelly figured out that i have to include
the id of every entry in the update statement. This is where the
problem is raised. My database is an Access database. The table i am
updating contains a Date...

does anyone experienced slowness when updating a dataset using
AcceptChanges?
when calling this code it takes many seconds to update the database
SqlDataAdapter1.Update(DsStudentCourse1)
DsStudentCourse1.AcceptChanges()
i'm also wondering because w/ out AcceptChanges the data is still save
into the database and it is now faster.

Hi All!

form's fields. The situation is the following one:

the BindingSource of the combobox to update the textbox. When selecting an
item in the combobox or when selecting a row in the grid, it is updating the
textbox correctly. The problem is when I apply a filter in the grid, and then...

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,...
