Does anyone know why the DA Update() would throw an exception?
I moved the database but I updated the Conn and the DA, currently
(trying)removing/replacing DS. Is there a another direction I should be
looking in? Does it matter if I move columns in the grid (everything is a
string anyways)? Does the DS need to be udated from the DT?
***************
int rowNo = dg.CurrentRowIndex;
dt = dt .Rows.BeginEdit();

I've got a strongly-typed dataset with 2 related tables in it ("Staff"
and "Roles"). I want to make a change to the parent Staff row and also
to its child Role row. I'm having difficulty figuring out the best way
to do this.
First question:
I can get myself a new instance of a row and make changes to it, but
presumably that's then a separate object from the original dataset
row. How do I reconcile my changes back to the dataset?

I think this is the right group to post to, so here goes.
My problem is this, I cannot update the datarow to save my life. Been
on this for 2 days now, and still am no closer to figuring it out than I
was before. I'm basicly taking date from some text boxes, trying to put
them into a datarow and using that datarow to update the database, but
its not working. The btn_update is where I am sending the information
back to the addclient...

Hi all,
<bitching and moaning section>
I am asking for any help I can get here... I am at the end of my tether... I
don;t consider myself a genius in any way whatsoever, but I do believe I
have a logical way of thinking that has served me well during my years of
application development with various tools...
But having been working with VB.NET now for close to a month... I am
beginning to doubt my abilities...

Hello,
I tried to update a row in a table by using the datarow and data
adapter. Unfortunately, it doesn't update.
I try finding that datarow and set it to "dr", I can see dr could be
just an instance of the row, but aren't linked to the table. Is that
why it doesn't update? If not, what is missing? Please help!!!
Dim da As New SqlDataAdapter("select * from Table1", cn)

Got a question about the side effect of DataAdapter.Update() and
DataTable.GetChanges().
Say I set up a DataTable and a DataAdapter in a class. Delete (Not remove)
a row in the data table and call the following method.
public void JobListDataTableFromAccessCommitChange()
{
System.Data.DataTable oChangeDataTable;

Any obvious reason here why data is not being loaded into the database?
SqlDataAdapter dataAdapter = new SqlDataAdapter(sqlCommand);
SqlCommandBuilder commandBuilder = new SqlCommandBuilder(dataAdapter);
dataAdapter.Fill(dataSet, "POI_Entity");
DataRow dataRow = dataSet.Tables.NewRow();
dataRow = 1;
dataRow = dataSet.Identity.POI_Entity_ID;
dataRow = dataSet.Identity.Chain_ID;

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:

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.

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...
