Hi All
I have a DataTable that has the AutoIncrement properties set, but when I add
a new row it doesn't use the values I'd expect and is causing an error.
For example:
MyTable.Columns ("PKColumn").Au toIncrement = True
MyTable.Columns ("PKColumn").Au toIncrementSeed = -1
MyTable.Columns ("PKColumn").Au toIncrementStep = -1
Dim oRow As DataRow = MyTable.NewRow
'// oRow("PKColumn" ) = 12 I'd expect it to be a negative figure, and for
each Row I add it decreases by 1
MyTable.Rows.Ad d(oRow) '// Causes error the second row that's added cos the
PK value already exists amd is unique.
Has anyone else experience this??
Regards,
Steve.

If you have statement like MyDataAdapter.F illSchema(MyDat aSet,
SchemaType.Mapp ed, "MyTable") running before, you cannot change PKColumn's
property in MyTable.

Hi John
I don't have anything like that running before I can see the properties of
the Column in the Locals window and they are correct, but when I create a
New Row it doesn't create the row with the PK column as a negative.

Steve.

we are having a problem when trying to serilalize and deserialize DataTable
When replacing the container to be ListArray or HashTable everything works
fine
The code is very straight forward ( see below), however when comparing the
DataTable before and after the serialize, it is not the same
The DataTable after the serialization contains only the string of class type
( Vclass in this class) but not the class itself
Any idea ?

I have a process that manages a list of trades. Each trade is a separate row in the table. I blast the process with 10,000 new trades in order to stress test it and end up with the below listed exception when I call the NewRow method. The number of times it happens is NOT consistent (sometimes a few times out of 10,000 and sometimes 1000+ times). The app is written in VB and I am using SyncLock everywhere the table is accessed but I am sure it...

I have an ASP.NET/VB app that updates values in a DataTable over the
course of about 3 different pages. On the way out of the first of
these pages, I explicitly build the DataTable from values in a
DataGrid, and set the PrimaryKey of the DataTable to be the first cell
in the grid (which is a UserID value). I then store the DataTable in
a session object, from which it is retrieved for subsequent pages.
All this seems to be working fine.

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

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'm a network technician in training and I need your help.
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...
