Hi Everybod
I want to update some controls in a form from another threads. I did it by passing the form to that thread and calling a delegate with Form1.Invoke, I want to have just one delegeate for all of my controls in the Form and dont define one delegate for each control. Some thing like to have a switch case in that delegate fucntion and passing control name to it..
what is the impact of this method in comparison with...

I start my thread job:

Hi guys.
I have two threads: a main thread and a background thread. Lots of stuff
happens in the background thread that means I have to update several (lots)
of controls on a form.
It is quite tiresome to have to write code to call MyControl.Invoke for each
control on the form, along with the delegates that are required for each.
Is there a better way to do this? What I mean is, if I could marshal the

I need a thread to run a subroutine which updates my main form's
progress bar. I've properly marshaled all UI updates to the main UI
thread, and after the main thread starts the worker thread, it waits
for the worker thread to complete by means of a while t.isAlive,
sleep(0) mechanism. But when my worker thread calls my
UpdateProgressBar routine, which calls Me.Invoke, the invoke call
blocks forever. But I can't figure out why the main...

I'm running an asynchronous Socket. In the ReceiveCallback method, I need
to append what is received to a textbox on the main form. I have this code:
Private Sub ToChatWindow(ByVal msg As String)
txtChat.AppendText(msg)
End Sub
I've never used a delegate or invoke before and I'm rather confused on the
topic. Hope someone can help.

I need to update my UI from a Process or worker thread. I did some readinf
and basically ended up adapting an MS example to fot my needs. It all made
sense until I tried it :)
My process makes calls to a Singleton logger class which in turn makes calls
to a delegate to add items to a listbox in my WinForm.
Here is the code that I have in my Form class to log output
<code>
delegate void AddOutputItem(string msg);

Hi,
I hope someone can help. I have written a simple form to demonstrate
my problem/question. The code follows.
The form starts a thread, which using delegates updates a label (Every
second adds another dot to the label). This works great. However,
when I put the GUI thread to sleep (Thread.Sleep), the thread seems to
stall. At first I was expecting dots to still appear, but obviously as
the GUI thread is asleep, they will not. ...

Hi,
I have a class which monitors a TCP socket. This will on occasion raise an event which can be handled by a GUI.
Now, I am aware of the

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...
