Hi everyone
I recently had the need for StringGrid object same as the one that
Delphi has. An object that helps show lists of other objects in a
simple grid. I searched the news groups and found none, so, I wrote
one and decided to share it with you.
It's a very simple one with few functions. I derived a DataGrid and
added to it a DataTable to hold the data. The object itself is
handling the synchronization between them, because...

Hi:
I am writing a WinForm app that contains a DataGrid control and a StatusBar
control. My goal is to update the status bar using events from a separate
class, as well as some other simple things.
The method I am writing queries a large dataset. As part of my feedback to
the user, I am updating the status bar when the connection is made and the
dataset is actually retrieved. The dataset retrieval method I have placed on
a separate...

I'm in a weird situation where I'm using ComboBox's in a DataGrid. When the
ComboBox selection changes, I'm currently storing the SelectedValue object
into the DataSource of the DataGrid cell. This is not what I want.
I want to bind a string to the datagrid, then bind the string and value of a
lookup table to the combo box. When the combobox lookup is changed, I
wanted to store the value in a different, unbound property of the bound...

I did a lot of searches and read something about
datagrids. But I couldn't find the answer of my simple
question, how can I show only my desired columns of
a table? for example I wrote this sql query:
OleDbDataAdapter1.SelectCommand.CommandText = & _
"Select illNameE From tblIllness"
OleDbDataAdapter1.Fill(DsIllness1)
But in my datagrid, I get (null) for other ccolumns instead

Dear all,
I have an application which collect information from a database and display
them in a dagrid.
I have apply to the grid a DataView object to get filtered information and
bind the grid to that dataview.
Then if my user click on a <ADD> button I would like to get the grid in an
edition mode and my user can fill up information directly in.

I'm getting data in a generic list class, which I'm not going to
change. I would like to
use it as a datasource for a datagrid or a gridview, but it doesn't
implement IEnumerable.
I'm wondering if there's a simple technique that would allow me to get
the data into the datagrid.

Hi,
I have a form with a control..(a button for example). Then the
control properties are displayed in a propertyGrid control.
Is there any simple way to remove some unwanted properties from the
propertyGrid....removing the "AccessibleName" properties by example?
Any example about how to play with the PropertyDescriptorCollection to
remove some properties??

Hi!
Let's say I wanted to create a very simple control that is nothing but a LED. That LED can be active or inactive. Depending on that state its color changes.
What is WPFs best practice to do so? Because I dont like the control the way it is right now at all.
LEDControl.xaml:
<UserControl x:Class="WpfPanelClient.Views.LEDControl"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"

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...
