Have one datagrid that displays all of the columns of both tables.
What's the best approach on updating a row from the datagrid back to the

Hi, I am trying to use a data grid in a web application in which I have
three tiers. The DataGrid is not set up to a data source, or a data adapter,
so everytime I make a change I send the cell information to another object
which forms an SQL query and makes the query to the DB (actually to a
DBFacade object). In any case, please see the code I have listed below for
my update DataGrid event. With this code, the DB is updated using the old...

Hi guys,
I've been trying to implement an editable datagrid and i have been
succesful up to the point where i can update my datagrid row by row.
However what used to happen was that once i updated one row, all of
them were updated so i immediatelly figured out that i have to include
the id of every entry in the update statement. This is where the
problem is raised. My database is an Access database. The table i am
updating contains a Date...

hello,
I have put thisup b4, but I think that people have misunderstood the problem, so I will make it clearer.
I have a problem updating a dataset that is bound to a datagrid.
The code that I use to set up the grid dgsimple to the dataset Mydataset and the table "Orders" is as below (see bottom of page)
My problem is that I can change data in the datagrid on the first row of the grid and the changes will be immediately written away,...

does anyone experienced slowness when updating a dataset using
AcceptChanges?
when calling this code it takes many seconds to update the database
SqlDataAdapter1.Update(DsStudentCourse1)
DsStudentCourse1.AcceptChanges()
i'm also wondering because w/ out AcceptChanges the data is still save
into the database and it is now faster.

I'm using the Framework 1.1, so I don't have access to the new
DataGridView object.
What I'm wondering is, is there a really simple way to bind a plain
datagrid to a database in such a way that changes made to cells in the
datagrid call an update on the corresoonding data within a database?
I've looked in vain for a really simple way to do this with minimal
coding, but I'm coming to the conclusion that I will have to trap the
events of...

Hey, I have never used a datagrid/dataset/adaptor/table method for updating
data, I have always used direct updates to the database so ADO is quite new
to me.
I have a datagrid and I change a value in one of the fields.
I hit save and the following code runs...
Dim da As SqlClient.SqlDataAdapter = New SqlClient.SqlDataAdapter("Select *
from MISRE_Threshold", cn)
da.Update(dsThreshold, "MISRE_Threshold")

Hi All!
I am with a situation where I am not getting the right updating to the
form's fields. The situation is the following one:
I have one combobox and one textbox. I am using the CurrentChanged event of
the BindingSource of the combobox to update the textbox. When selecting an
item in the combobox or when selecting a row in the grid, it is updating the
textbox correctly. The problem is when I apply a filter in the grid, and then...

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...
