Hi All,
I am very new to C# as well as to SQL. I need to write an application which
is connecting to SQL DB and getting all the user's tables and after create a
dataset for all the tables in the database and create an XML document with
all the info.
The problem is, that I can do this if I know the table name. However, what
if I don't know the table name nor I know how many user's tables in the
particular database.

Trying to connect to MySQL db on localhost, and populate datagrid from a
dataset using code inline method.
Getting the following compile error:
Error Message: "CS0246: The type or namespace name 'CoreLab' could not be
found (are you missing a using directive or an assembly reference?)"
I downloaded the add on for connecting to MySQL using ADO.NET and installed
it, but am still getting this error. Anybody ever run into this before?

Hi !
I get the error below sometimes when retrieving a big amount of data using Datadapter.Fill(dataset,"table"). But when I send the command Fill again, there is no error. Is it a fault of IBM.Data.DB2.iSeries; Version: v1.0.3705 (is there an newer one for OS/400 Version ist V5R3 ?) or is it a hardware faoult (memory of as400 or pc) ?

I have a dataset with Customers, Orders, and Items tables.
It has datarelations set between Customers-Orders and Orders-Items
It has foreignkeyconstraints with update/delete rules set to cascade
for Orders & Items.
The dataset is filled with Customers and their related Orders and
their related Items.
What is the most efficient way to create a second dataset that is a
subset of the main dataset, but only has data for Customer_id = "1"

Why am I getting an error when I passed by ref a dataset to a new form? The
message reads "cannot convert from 'ref Paimport.unixAccount' to 'ref
System.Data.DataSet'.
Paimport is the name of the form where the dataset UnixAccount is created.
I created the dataset using the designer tool and not by code. So it's like
a type or class which I then declare an instance of it :
UnixAccoutns dsAccounts = new UnixAccoutns ();

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:

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,...
