Hello,
Since I cannot query a DataSet directly, and I would like to maintain
it's data, how would I use an adapter (SqlDataAdapter or DataAdapter) to

Example: Could I?
SqlDataAdapter adapter = new SqlDataAdapter();

I have code that allows the user to filter out car models, such as Chevy
PickUp, Chevy Truck, etc. by region. When i added code for the Chevy Cars and
filter by region i'm still getting the Trucks and Pickups in that region. How
can i only get teh Cars, for the selected region?
Code:
with dvCars 'dataview
.Table = dsCars.tables(0)
.RowFilter = "(Make =" & selCars & "'" & ") AND (Region=" & "'" &

I'm using a DataGrid with a DataSet and I'm trying to filter the data being
displayed, using the following code as a test:
DataView theView = new DataView(theDataSet.Tables);
theView.RowFilter = "'Record ID' = '0'";
theView.RowStateFilter = DataViewRowState.ModifiedCurrent;
Debug.WriteLine(string.Format("RowFilter = {0}", theView.RowFilter));
RecordDataGrid.DataSource = theView;
RecordDataGrid.DataBind();

Hi
I am working with rowfilters in dataviews.
I would like to filter for empty fields (= null value in the database)
I found this sentence on msdn:
****************
To return only those columns with null values, use the following expression:
"Isnull(Col1,'Null Column') = 'Null Column'"
*************************'
So I tried like this:
mainDataSource.RowFilter = "Gender = 'male' and " & "Isnull(floor,'Null

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
