I'm using an in-core DataSet as an image of my application's
'database' (a multi-table Access97 mdb file). Updates are made to
the DataTables within the DataSet via forms with bound TextBoxes,
then written to the database... or at least that's what's supposed
to be happening.
Unfortunately, I've discovered that while it appears that when I
create a new record/row I'm successfully updating the Access
database, once the Update is...

Hi,
I have a problem understanding the SqlDataAdaptor and the DataSet.
I have a dll which has various methods for running stored procedures etc. It
also has a method which allows the client to return a DataSet from a table.
The client can modify this DataSet and I have wrote a function which will
take this DataSet back in and update the Database.
I assume this is what is meant with disconnected datasets?

Hello,
I have an application using an xml dataset to store app and user settings.
The problem I am having is related to writexml. I have a save button on my
application that updates the dataset and then using the writexml(...)
function saves the dataset to an xml file. I have noticed that the file does
not change everytime I click the save button. I get no errors but the
writexml function does not seem to be updating the xml file.

succesful up to the point where i can update my datagrid row by row.

the id of every entry in the update statement. This is where the
problem is raised. My database is an Access database. The table i am

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:

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.
