I have a windows form with a bunch of textboxes, comboboxes and three datagrids. My dataset has 4 tables and the necesary relations. Basically it's a master page with three detail grids. My problem is that when I move the position of the BindingContext the datagrids reflect the change but the textboxes and comboboxes don't.

Hi group. I´m trying to add new records to a sql server data table with:
BindingContext.AddNew();
This sentence clear all my textboxes and not add any record to the database,
the I use the next code, but appears an error about the duplicate primary
key, I suppose that this code is valid if I don´t use the databindings of
the textboxes :
DataTable myTable = dataSetUsuario1.Tables;

Hi,
I retrieved the employee table from the Pubs database into a single dataset
called, dataSet12. I dropped two textbox controls and a datagrid control
onto the same form and bound the controls at design time to dataSet12's
employee table. Now I want to move through the data by pressing a
button....
This code will change the data in the text boxes:
this.BindingContext.Position += 1;

Hi all
I have a data-bound Windows form bound to a strongly-typed dataset. Upon opening the form, I would like to Find a specific record based on a parameter I've passed to the form, and display the data in the appropriate textboxes, etc. I would also like to have the entire table opened (i.e., not just the one record I've found) as I would like to navigate through the records
My table is called "AP_TBL_Vendors.
The problem is that I...

I have a simple datagrid on a form. I used the wizard to create the
form. I have navigation buttons that I made myself.. This is the next
button:
Me.BindingContext(objSeasonsDS, "Seasons").Position =
(Me.BindingContext(objSeasonsDS, "Seasons").Position + 1)
The position is always 0. If I hit the next button, it becomes 1, then
when I hit it again, it's back to 0 and gets set to 1 again. The

I have a question on bindingcontext, bindings, and
controlbindingscollection. I understand the very basic idea, and I think I
should be able to do this, but I'm not sure how.
First problem: I have a combobox and a textbox on a form. I also have a
"Customers" table loaded into a dataset. I set the combobox.datasource to
the table in the dataset, and add a binding to the text property of the
combobox for the 'Name' field. I also add...

I have created a UserControl that encapsulates a third party data grid.
My goal was to create my own DataSource and DataMember properties that
forward the binding to the third party grid, then use binding like
normal.
The problem I am running into is that my UserControl ends up with a
different BindingContext then the ParentForm it is contained in and
thus all other controls on the parent form. (I want various controls
on the form to...

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,...

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.

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...
