Is there anyone who can point me to a good tutorial on how to create a
multithreaded class library?
Class A is a controller that starts up a number of threads of code in Class
B. Class B raises events back to Class A.
I want the code in the eventhandlers of Class A to run on the thread that
created the object.
In a Windows.Forms control this is easy by calling Control.BeginInvoke, but
how do I do this in a normal Class?

Hi,
I check data validity in html form by JS. Something like
for (i=0; i<document.form.elements.length; i++) {
chechkValidity(i);
}
Unfortunately, the form has about two thousands elements (it is
statistical questioning form for companies) and execution of this one
cycle takes about twenty seconds.

Alan, you can achieve this by using XMLHttp Async
functionality in a javascript file.
Create an aspx page in which execute long running SQL
query, then do an XMLhttp post to that page from a js
function.
In the javascript create 2 funtion
Call LoadData in the window onload event.

I would like to have one column in my DataGrid that content acts as a
hyperlink.
In addition to that I would like that the content is databound to a DataSet
source.
If I create a hyperlink column in VS.NET I loose the databinding feature for
that column. If I choose a data bound column I don't get the hyperlink
formatting and actions.

This is driving me nuts, it is such a simply thing to do but i cannot for the
life of me work out how you are suposed to do it. I want to update the data
in DropDownListB based on what is selected in DropDownListA. I am not trying
to do anything fancy with AJAX, i am happy to use Post Backs. If it were two
controls just on the page then i would simply specify a control parameter for
the SelectCommand of the SQLDataSource control which...

I've spent loads of time Googling to try to work this one out and I'm
sure it's something obvious.
I get an InvalidOperationException reading "Databinding methods such as
Eval(), XPath(), and Bind() can only be used in the context of a
databound control" when I start my page. Unless I'm missing something
obvious, this is *not* the same issue as the "2-way databinding
cascading lists" issue in...

Hi all,
I am running a VS 2003 .NET project on my client machine (Win 2000 SP4,
..NET framework 1.1), running an ASP.NET application on a remote web server
(Win 2000 Server, IIS 6.0, .NET framework 1.1).
The application implements a Progress Bar webcontrol, that pops up in a
window, using the HttpHandler interface, on the event of a button click. The
handler's process request routine reads the status of the progress by
querying the...

Hi!
I am creating a composite control the does some of it`s own data access.
I want to display a progress bar between the time the page is loaded and the
control place holder is displayed and final display of the data from the
database.
I was thinking of manually opening a second thread in the Render method, but
nothing is displayed before the render method exits anyway.
Anyone know of a good way to do this?
I have been working on this...

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'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...
