I'm using a DataTable in my application. I am able to load rows into the DataTable quickly. What's puzzling me, however, is that when I update a set of cells in the DataTable, the update is really slow
my update code amounts to
dataTable.BeginLoadData()
dataSet.EnforceConstraints = false
tr
for(iRowHandle = 0; iRowHandle < iLimit; iRowHandle++

I keep getting a concurrency exception the second time I make a change and
attempt to update a dataadapter. It appears this is by design, so there must
be something I can do to avoid it.
Example:
I have a dataadapter that contains one table with one row. I change the
value of the 'FisrtName' column in that row from Jack to John. I call
..update on the dataadapter it goes through fine. Now I change that same
column in that same row...

OK, I hate myself for asking this, it's the worst question I have ever asked
but it's worse not to ask:
¿How do I update a datatable in vs 2005? I mean, I am using a typed dataset,
a datagridview control and SQL express. I tried this code on a separate
button to commit changes to the database:
Private Sub cmdOK_Click(ByVal sender As System.Object, ByVal e As
System.EventArgs) Handles cmdOK.Click

Some of you may have seen my earlier thread “PasswordHash NULL problem”. I’ve started a new thread because investigation has shown that the problem is actually quite different than I previously stated. Also please note that this is unrelated to another of my previous threads, “dataAdapter.Update problem”, which incidentally has been resolved.
I’m learning SQL. I’m accessing database SQL2008 AdventureWorks, table Person.Contact, which has a...

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,...

Hello
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.

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...
