Hello!
I'm writing simple database application. One table in the database stores
some information about keywords (among other, keyword name, id number and
description). Description is stored in rtf format.
Following code is responsible for data binding (lstKeywords is
ListBox,rtbDescription is RichTextBox):
lstKeywords.DataSource = manager.KeywordsDataView;

Hello
I'm trying to run the code below, but I'm running into a problem
It is populating a listbox, based on whether or not the user enters data into a text box. If they enter something, it returns only that record, if they leave it blank, it returns all records. This works fine.
Now I have text boxes that are linked to what is displayed in the listbox. If the user enters nothing, it works fine, and if the user enters something it works fine,...

I have a dataset containing a parent table related to a child table. The
child table contains an ID field (which is configured as autonumber in the
datatable), the ID of the parent, plus some addition fields.
I'm able to get the datagrid to be properly populate with only the child
records relating to the specified parent by setting the
..DefaultView.RowFilter property.
Currently, to properly add a new child record, I need to manually...

I'm binding a Combobox to an Arraylist, and I'd like to set the ValueMember
and DisplayMember properties of the Combobox. Is this possible, or do I
need to bind to a DataTable?
Thanks

Essentially, InsertAT is broken!
For the past couple of hours, I've been getting this "Parameter name:
'-2147483550' is not a valid value for 'index'." error.
Apparently, its caused by having manually inserted a row in the table
bound to the Combo box. The InsertAt Method of adding a row just does
not work.
Hope this helps anyone with this problem.

I'm trying to fill a listBox control with string members from an array
of objects. I think using data binding is supposed to be the easiest
way to do this. I've never used data binding before and am having
trouble getting it to do anything. The relevant code is below, followed
by a better explanation of what I'm trying to do.
// pseudocode start
public delegate string StepMethod();

Hi,
I'm trying to create a form that shows table rows in a listbox. Several
comboboxes expand the foreign key fields into text values from the parent
tables, and there are also some textboxes for the non-foreign key fields.
When the user clicks on a row in the listbox, the comboboxes' SelectedItem
changes to reflect the foreign key selections in the currently selected row.
That part is working fine. I also want the textboxes to change 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...
