Hi NG
We want to load controls dynamically and create them on a WinForm. Doing so,
we seem to loose type information. The scenario is as follows: The class
MANCombobBox inherits from ComboBox and implements the interface
IReportDataSource.
This works:
Control c = new MANComboBox(); //MANComboBox inherits from ComboBox and
implements the interface IReportDataSource

Hi,
I am writing a GUI application. It will have a number of user defined
controls( I plan to use/create a user defined control that will output alarm
states that the user can also select and will open a dialog to give more
detailed information) .
The number of controls on the main GUI will vary from client site to client
site. I would therefore like to populate the dialog with these controls
dynamically.

I've a form where I load two user controls dynamically.
User Control-1 has a no.of dropdowns and based on the
selection I typically

Hi,
I can use following syntax to add user controls directly to my pages :
<XYZ:myControl parameter1="value1" parameter2="value2" runat="server" />

and parameter2
Now my question :

Hello,
I am developing a page that has several custom web user controls that
need to be loaded dynamically. Some of the controls are loaded based
on the action (button-click) of a different control in the parent page.
Currently what I have to do to make this work is set a session
variable to load/unload a particular control and do a Server.Transfer
to the page itself from the Button_Click event. Is this a good way of
loading controls...

I'm building a vb.net Forms project that is getting data from a SQL Server
database.
One of the main goals of the project is to be really responsive to events,
such as textbox change events. I have a textbox for searching, a listbox to
display the searched results, and a big textbox (memo) to display the
clicked-results of the listbox item.
My question is: should I load the controls with objects, and therefore store
everything in...

I need some advice on handling dynamically added controls in a
GridView.
My app takes an uploaded CSV file containing addresses, converts it to
a DataTable, databinds the DataTable to a GridView, accepts information
via dropdowns embedded in the first row of the GridView about which
incoming fields should go to which database fields, and writes the data
to the database.
The incoming data has an arbitrary number of columns so I create...

Hi,
I need to find a way to place multiple textboxes and other controls
dynamically on a web form, I tried to put a placeholder on a form then
create and add controls dynamically into the place holder. It is not
working, all controls added disappear after the postback.
I tried to find a working sample on Internet with no lucks, some samples are
able to keep the controls after the postback, but all values entered before
the postback...

I can think of a lot of reasons why this might need to be done but as
far as I can tell it's not possible. I've been looking for a way to
add HtmlTableRows to a table using a button click for a while and it
seems it's not possible because the row that gets added with each
click won't get recreated after a post back. After all the reading it
seems that any dynamically created controls must be created in the
Init event to be recreated after...

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,...

I am currently learning how to create and manage the different types of VPNs and I have a question about LAN-to-LAN VPNs.

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...
