I am using the following code instead of a very lengthly select case
statement.
(I have a lot of lookup tables in a settings form that are selected
from a ListBox. The data adapters are given a similar name to the
table. Rather than making a long Select Case that could become
obsolete if lookup tables are added and the source table of the
ListBox is edited I came up with this code.)
This code works but of course it gives me build...

I understand the use of Application.DoEvents() to process all outstanding
messages on the message queue in a winforms application if you have long
running process on the UI thread. But can anyone explain to me why I need to
call DoEvents when I am using a COM component that calls back to into the
..Net application? - If I don't call DoEvents after receiving a callback then
sometimes no more messages are pumped, it appears that the message...

I would not have thought that getting a DataGrid connected to a DataSet
(read in from an XML file) would be this complicated. I cannot get this to
work. I have read everything I could find and modeled all the examples
given but this grid just refuses to behave nicely.
The code is listed below as well as the XML schema and XML data.
The connection between the data set and grid seems to work just fine. What
won't work is the display...

Hi all.
I'm using the Property Grid control in a control to manage a windows service
we have developed here. The windows service runs a set of other jobs that
need to be managed. The control is used to view the state of the running
jobs and schedule new jobs. The control also runs in the context of
Internet Explorer (we do this so the administrators of the jobs can always
receive the latest control). The property grid is used to...

Hi,
My problem is this, I have a search screen which creates a query that
performs a search on a large database. The results of this search could, if
the user requires, return many many rows (20,000).....
In other languages, when faced with this problem, you can run a query and
link it to a datasource and link the datasource to a table. You can then set
an option called packetrecords to 20. If your grid has 40 rows, then as it
populates...

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...

Hi I was wondering if someone could help me. I have not used
activewidgets before and i wanted to know if it is possible to use it
to populate a grid that exsists on another's webpage. That is, rather
than entering user input to their webpage manually use active widgets
to enter the data? I don't know if it is appropriate to ask this of
this program?
Any assistance would be gratefully recieved!
Thanks

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...
