Here is my basic problem. I have a form that executes a
cpu instensive algorithm occupying the first thread. When
the algorithm is executed another form pops up telling the
user the progress that has been made.
Whenever I attempt to update my frmProgress, the events
are put placed at the end of the thread's queue and
executed after my algorithm is finished. Using the
frmProgress.Label.Invoke method with delagates, I have

hi all,
I'm having a few problems whereby my application is hanging when using the
Invoke method of a form's control.
Basically, when a user clicks a button on the form, it calls a remote
function, which in turn fires an event that is caught by the form.
The form then need to add a value passed in the event to a form object,
however, when using the Invoke method, it just hangs.

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...

Please help, anybody.
I am trying to write a program so that it can launch an exe file ( which is
also genereated in C# ) and then simulate the button clicking and invoke the
methods inside the exe. The button clicking part is working fine, but I just
cannot get the method call.
Here is my program snippet.

Ok, This is weird... I just love quirks with .NET 2.0
I create a Window Application in VS IDE 2005
I create a Console... via AllocConsole, all it fine
I create an application context, set the mainform to a form, for
'theContext'
I run the context via Application.Run(theContext)
The minute the Application.Run is done, all events that SHOULD go to
the Console window are blocked and seem to be routed to 'theContext'
mainform.

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
if(InvokeRequire) {
EventHandler d = new EventHandler();
Invoke(d, new object{sender, e});
} else {

I'm teaching myself about delegates and the Invoke method, and I have
a few newbie questions for the gurus out there:
Here are some CSharp statements:
1. public delegate void MyDelegate (int k, string s)
2. MyDelegate MyDelegateVar = MyMethod
3. MyForm.Invoke (MyDelegateVar)
Some questions:

Trying to understand why one way works but the other doesnt.
I have not tried to create a simpler mdi/child/showdialog app for posting
purposes (I think even this would not be so small or simple). I am hoping
the description will generate some ideas I can check out.

Switching to UI thread using Invoke(), everything seems good.

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,...
