I have a 3 table in my DataSet that I'm filling with data. After I've
filled these 3 tables, I'm then trying to run a query that will fill a
4th table in the DataSet with data from the three tables that are
already pouplated.
When my code tries to fill the 4th table, ReportData, I receive the
following error message: Invalid object name 'tmpPROJECTINFO'. Invalid
object name 'tmpContacts'. Invalid object name 'tmpRECEIVEREC'.

I have a datagrid that has to be filled in a WinForms application. The
data comes from an Oracle database.
The normal procedure would be filling a dataset, but I have the problem
that there are over 100.000 records in the tables, so this has very low
performance when executing.
I then tried using an OracleDataReader, but for some reason, I cannot
bind my reader to the datagrid, I get the following error:

Hi,
I automated a process (using a recordable MACRO) in excell to open msaccess query and retrieve data (from an Oracle database) - said data then to be compared via VLOOKUP with data in a second worksheet
I then hoped to tinker with the recordable MACRO, so that the second time the query is made to the ORACLE database, a prompt asks for the unique key of the record to be retrieved. Hopefully, I'd like to amend the code further so that...

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,...
