The following code retrieves data into a dataset, and then creates a dataview
with a filter. This dataview is then attached to a combobox. When the
effective date changes, I would like to see the newly filtered data without
having to create a new dataview each time. Is that possible?
Also, do I need to attach the dataview to the combo box each time?
if (AgencyCounties == null || sPropertyState.Text != prevPropertyState)

I have a window application. On one of the form, there is a listbox and a
few combox. The lstSchItem has a dataview as a datasource. The comboxes are
bind to its selected value but through the dataset table. Now when I change
the selection in the lstSchItem the comboxes are staying the same and not
reflecting the changes. I tried changing the binding to the dataview.table
but the comboxes are still not changing to reflect the...

I have a form with a dataset and a datagrid.
I created a dataview on this dataset.
When the user modifies the datagrid, I look up this record in the dataview
to make sure it is unique.
Here is the confusion.........
I thought that the DataView is the view from the dataset, but it seems that
the dataview has the records that are in the datagrid, because everytime I
search for a record that I know is NOT in the dataset, it finds it. I...

I want to create a dataview with a sort on multiple columns. However,
when I use FindRows, I only want to search some of the columns, not
all. Is this possible? I have not been able to make it happen.

objKeys(0) = "CL"
objKeys(2) = 4000

I am pulling master data from one master table and detail data from two
detail tables. The rows from the master data are displayed in textboxes on

with a Dataview object using the dataview.Rowfilter property. This is sort
of working except that I am getting an except on one of my...

Hi
I'm hoping that somebody can help me with the following:
I have a DataTable which I'm displaying in a DataGrid. I am changing values
in this grid which need to be passed back to the DataTable and then back to
the database source.
In the grid, I sometimes only want to show some of the rows i.e. I filter
it. I do this by using a DataView to the DataTable and then filtering the

What is the real difference between the DataView and the DataGridView?
Is the DataView even a control or is it merely a class? With methods
that allow you to edit rows and columns it seems like it would be a
control that you could drag and drop on a form in the designer but I
cannot find the DataView control in the toolbox. I have used a
DataGridView before but I was wondering if DataView has better
functionality.
Thanks!

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,...
