Not sure what group this question is better suited for so I sent it to both.
I have a DataTable which contains 1545 rows. I have a method that returns a
DataTable of distinct rows based on one column. This table ends up with 386
rows.
I need to loop through the smaller table and filter a DataView based on each
row from this table.
This loops takes ~5 secs. Is there anyway to improve this?

I have a dataset (called adset) which has a column called "Large" which is
either an integer 0 or 1.
I am creating 2 dataviews, one which should display the 1's and one which
should display the 0's using the following code:
DataView largeview = new DataView();
largeview.RowFilter = "Large=1";
largeview.Table = adSet1.Tables;
DataView smallview = new DataView();

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();

I have an orders table. Each record in the orders table contains a customer id.
I have a customer table. The primary key of each record in the customer
table is the customer id.
After getting a subset from the orders table, I need to take the customer
ids in the orders table subset, and list each record in the customer table
that has a matching customer id.
If I were in t-sql, this would be an easy inner join. In this case, I get

Hi
I am in the process of developing an inventory application in visual basic. I keep coming up against a problem with using the dataview.rowfilter property.
Basically what happens is this:
-a global dataview is created
-The user enters new part information into a form.
-A function is called to check to see if the part is a new part (so that two identical part numbers are not added to the database.
-The check is done by setting the...

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,...
