I have relational integrity set up in my sql server 2005 database that
prevents cascading deletes in some cases.
I'm using a bound datagrid view and a tablenavigator. When I click the
delete button on it then the save button, I get the message saying a foreign
key constraint does not allow the deletion, but the row is no longer shown
in the datagridview. Only way I get to see it is to close my form and open
it again, then row is there OK....

Hi all
I have a small problem.
I have a datatable with 8 columns. But it is only data in 5 of the columns.
Data for the remaing 3 columns is in another dataset.
I Want to run trough the datatable and fill out the remaining data.
My code so far:
if (this.fetch("custinfo", "fetchCustInfo", out customers, parameters))

Hi All,
I have a bound DataGridView control where I wish to add a new row. The
simple solution turns out to be add a new row to the underlying
datatable object and the changes will automatically reflect in the
grid. However, I seem to have caught something bad.
My query is something like this:
select * from where orderid=x

I have a Datagrid that is bound to a Datatable at runtime. I allow the
user to select a number of rows using the mouse and then click a button
that says "check selected rows", which then cycles through the selected
rows and sets a check box field in the datagrid (and thus the databound
datatable) to checked/true. It works like this:
Dim cel As DataGridViewCheckBoxCell
For Each row In DataGrid.SelectedRows
cel = row.Cells(0)
cel.Value =...

Hello. I have a DataGridView that is bound to a DataTable. If the user
types in values for all the columns for the first row, then clicks
into a column in the second row (empty), and then clicks back into the
first row he just typed, then an empty row is added to the
DataGridView. I'm guessing that somehow the AddRow function is being
called when the user clicks in and out of the empty row. I don't want
this to happen. A new row should...

I have made a service that sends a datatable with person information to a client. In the forms init event I call the service to retreive all persons from my service and displays them in a datagridview.
In the form I want to be able to filter on e.g. first name. I have used the select method to filter on the datatable but it only returns datarows and not datatable which I need to set as datasource in my datagridview.
Also I can not add the...

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.
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...
