Hello,
Is it possible to find out how many methods are listening to a certain
event? For example, if a number of methods subscribed to a controls DragDrop
event using +=, can I find out how many methods in total are listening to the
DragDrop event of the control?
If I can't find out the exact number of methods listening to the DragDrop
event, can I somehow remove all listeners of that event at once? I tried
using m_Control.DragDrop =...

"DragDrop registration failed" is the error message I'm getting on
frmTasksInstance.ShowDialog() in the snippet below:
frmTasks frmTasksInstance = new frmTasks();
frmTasksInstance.ShowDialog();
frmTasksInstance.Dispose();
There's no dragging or dropping involved. The same pattern of code works
fine with other forms.

I'm writing an app that requires drag and drop operation between a ListView
and a TreeView control. (The source is the ListView). During the drag drop
operation I want to be able to detect the target node in the treeview and

COM version of the...

Hello,
When I am attempting to start a form (with DragDrop enabled) within a
new thread, I get the following exception. This is ONLY the case with
..NET 2.0 and did not occur in 1.1. I ABSOLUTELY MUST start this form in
a new thread. There is no getting around this. The fact that it
functioned properly when compiled for 1.1 is highly irritating.

Could you please look at the following piece of code and try to...

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,...
