I wish to supply the formating as a parameter, I have tried OleDbDataReader
but get a null ref.
just can't seem to get this to work. I think this has something to do with
ExecuteReader.
also can't seem to use this as the first pram
OleDbDataReader reader = new OleDbDataReader()
i.e

Hi all,
I''ve created an OleDbDataReader that will contain the number of records that
the used SQL query will return. I'm then using a while loop to loop while
the OleDBDataReader object has records. I would like to know does the
OleDbDataReader contain the actual information on each record i.e. the fields
in the database and their values? Or does the ExecuteReader command only
contain the number of records present from the used SQL...

Hello,
I am using the following code which works. My question is does the
OleDbDataReader need to be closed and then re-executed for every control?
Is there a more effecient way of doing this other than using a loop?
Thanks in advance, Steven

Hi All,
I have a situation where multiple applications are sharing some pages/
controls.
So, I have a separate common project that has the common pages/ controls.

Greetings!
I have a database created in MS Access that has some fields containing
Currency data. Every time I try to use one of the OleDbDataReader's
GetXXX() methods to read it, I get an invalid cast exception. Is it
possible to use the OleDbDataReader to get the value of a currency field in
an Access database? If so, how?
Rob, who probably shouldn't even ask this question, since the
OleDbDataReader is too simplistic. I should...

While I understand that Server Side Includes still work, I realize it's
not the best practice for sharing code such as a common set of includes
between screens.
In ASP.NET I've already built several User Controls and such for sharing
code between screens, but this typically was used things such as menus
and headers and footers.
What is the best practice in 1.1 for sharing code such as a common set
of functions used by multiple screens?

Hi. I'm writing controls that have to query the database, and it
bothers me that I might have several of these controls on a page that
each create, open, and close their own connection with the same
connection string, and the page class has a connection object too.
I'm using the code-behind way of doing things, and I considered
leaving the database connection open as a field in the page's class
and somehow letting the controls use 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

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.

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...
