Hello all,
I have a DataTable which I am building column by column and adding rows
after each new column. The DataTable columns match the columns in my
database table. I'm building the DataTable first and I then want to roll
through the DataTable while in memory checking for errors and then commit
the rows to my database table (btw this is in ASP.NET). Is it possible to
have data in a datable before attaching at DataAdapter? I'm a...

I have a datagrid that is carrying all fields of a record...except one. Now
I want to update the underlying database via a dataadapter. The update is
working but the field that is "left out" is not there, of course. How do I
get that field back into the datatable for the database update?
TIA,
Larry Woods

Hi,
I thought I had this sorted this morning but it is still a problem.
My application has a DataAccess Class.
When it starts, it:
Connects to a DB (OLE DB)
If it connects it uses an OleDbCommand with an SQL String and the connection
it has a DataAdapter with the command
then it fills the DataSet's DataTable with the streamed data.

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...

In VS2003 I used to be able to drag a SQL Server table from Server Explorer
onto my webservice (in design mode) and it would automatically create a
DataAdapter for me. This doesn't work in VS2005 anymore (crap) - is this by
design? Does anyone know?
Now if you create a DataAdapter in VS2005 (on a webservice project) it
generates the SQL statements and puts them in a .RESX file (i.e. the UPDATE
and INSERT SQL command text). Then the...

I create a simple DATAADAPTER in a webservice project. It creates the
UPDATE, INSERT, DELETE commands for me - no problem.
In vS2005 it creates these commands as RESOURCES in the RESX file (i.e.
strings). The problem is whenever I try to test the webservice I get:
System.Resources.MissingManifestResourceException: Could not find any
resources appropriate for the specified culture or the neutral culture. Make

What is the diffeence bewtween a dataAdapter.InsertCommand and
dataAdapter.SelectCommand (and dataAdapter.UpdateCommand for that matter)?
Dim da As SqlDataAdapter
conn.Open
da.SelectCommand = New SqlCommand
da.SelectCommand.Connectoin = conn
da.SelectCommand.CommandType = Command.Text
da.SelectCommand.CommandText = "insert Into tbl1 Select * from tbl2"
da.SelectCommand.ExecuteNonQuery

I can read in an SQL table ("Person.Contact") from AdventureWorks and step through it one row at a time, but when I try to save a record, either one I'm inserting or one I'm editting, I get the following exception:
Incorrect syntax near ','. Must declare scalar variable "@ContactID".

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,...

Dear forum friends,
With the development of smart home technology, a variety of wireless communication protocols have appeared on the market, such as Zigbee, Z-Wave, Wi-Fi, Bluetooth, etc. Each protocol has its own unique characteristics and advantages, but as a user who is planning to build a smart home system, I am a bit confused by the choice of these technologies.

Let's talk about the concept of autonomous AI software engineers and no-code agents. These AIs are designed to manage the entire lifecycle of a software development project—planning, coding, testing, and deployment—without human intervention.
