the update method of the data adapter the command builders update command

I have a dataset containing 2 tables. I need to fill a datagrid using
data from both of these.
If I could create a SQL Statement to fill the datagrid, it would look
like this:
SELECT fields.fieldname, fieldvalues.value FROM fields, fieldvalues
I am having trouble finding documentation explaining how to populate

I'm wondering if there is a limit of a single select, delete and insert statement (command) to each dataadapter? On a form, I have a dataconnection that is shared by 3 dataadapters, one for each of three tables in an Access database. Each was created in the form designer and each has a datatable that was generated in the designer. I have no problem filling the datatables and inserting the rows into the Access tables. I DO need to select the...

Is it OK to have more than one OleDbDataAdapter for a
single MDB file?
The first adaper to the MDB is only doing Selects. That
is working fine.
Though my second adapter is unsuccessful in performing
row Deletes.
Thanks!

Hi Everyone,
I have been writing xBase applications for many years but I am new to
VB/SQL for larger applications.
In xBase, I would start the main program (form) by opening up all the
datafiles (dbf) and indexes (cdx) that I would need to reference
throughout the application. I would also keep these files open
throughout the application.

Hello folks,
I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".

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,...

I am currently learning how to create and manage the different types of VPNs and I have a question about LAN-to-LAN VPNs.
The last exercise I practiced was to create a LAN-to-LAN VPN between two Pfsense firewalls, by using IPSEC protocols.
I succeeded, with both firewalls in the same network. But I'm wondering if it's possible to do the same thing, with 2 Pfsense firewalls...
