I have 4 columns in my sql database table. I added a data adapter , data set
& a data grid to view this information. But the data grid is displaying those
4 columns TWICE , i.e in the data grid i see 8 columns.
In case this is useful, the primary key is Serial no. which is an identity
....i.e everytime a row is added to the database, it increments by1. Also,
when i configured the data adapter, it couldnt Generate the UPDATE &...

Hi,
I have a question regarding data grids
My application requires me to use a grid for displaying data, however
I would not be using a database for procuring the data, instead I
would be exposing interfaces for other methods to pass me the data
that needs to be displayed. In such a case is the data grid the best
control to use in .NET?
Also if I am using a data grid, how can I obtain the value in the
current cell of the data grid?(where...

Hi,
I'm using a ComboBox, some Textboxes, and a DataGrid to represent a
many-to-many relationship between Person and Course. Each time that I change
the value in the ComboBox (which for now is the OID of Person), the
information of the person matching the selected OID is shown in the Textboxes
(Name, Address, id, etc) and the courses this person is taken are shown in a
DataGrid (course name, price, etc.). This is working well so far, I...

Hi, I wish to know how to display a collection of object which is a
property in another object in a data grid in VB.Net.
For example, I'm displaying a collection of vendor objects (in
ArrayList) in a data grid, while I wish to display the products
supplied by the vendor (which appears as a collection of product
objects in the vendor object property) in another grid.
I wish to know how can I accomplish such task. I used data...

How do I get the data bindings for a control that is bound at design time?
I'm binding a DataGridView control to a data source at design time, using a
BindingSource control. I set the grid's DataSource property to the
BindingSource control, which the Data Source Configuration Wizard created
for me.
The data binding works fine when I run the app, but I can't get a reference
to the DataGridView's data bindings.

After reading a tutorial and fiddling, I finally got this to work. I can
now put two tables created with a DataTable class into a DataRelation.
Phew! And it works!
Dim tblSliceInfo As New DataTable("SliceInfo")
Dim tblSliceRatings As New DataTable("SliceRatings")
'.... All the adding datacolumns, datarows, etc. goes here..
DatasetInit.Tables.Add(tblSliceInfo)

I found the following code to transfer datagrid data to an Excel file.
Is this written in C#?... I'm a vb.netter. I'm just not sure where to
place the code to experiment on it. Should I place it in the event
handler for a form button. Is there other ways to accomplish this? I
looked at some on the web and usergroups, but was confused as to the
functioning. BTW my datagrid is enclosed in a <div></divfor ease of
scrolling if that would...

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,...

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. Imagine an AI that can take a project description, break it down, write the code, debug it, and then launch it, all on its own....
Now, this would greatly impact the work of software developers. The idea...

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...
