OK, maybe this is my opinion, maybe these are bugs.
Given the folowing:
I have a NotifyIcon on my Form, a Context menu associated with the
NotifyIcon, and a MenuItem on the ContextMenu set as default. When the
default MenuItem is clicked, there is code to no longer show the NotifyIcon.
What I feel should happen is when I double-click the NotifyIcon in the
system tray, it should perform the default menu item's Click event.

Can anyone tell me if there is a workable method to get the mouse cursor
position on the screen or the NotifyIcon position? I need to display a
context menu for the NotifyIcon when clicked and I'd like it to display
based on the relative position of the tray icon or mouse pointer if
possible (whichever method works).
Any help would be much appreciated.

I've been working on an application which has a NotifyIcon (system tray
icon), and a corresponding ContextMenu. I want to be able to update this
menu dynamically. However, when I make changes to the menu, it seems to
disappear. This only breaks when the context menu is tied to a NotifyIcon -
not to any other control.
Below is a C# file for a form which should illustrate this (at least it does
on my machine!). The same contextmenu is...

Sorry Ive added this twice (sortof) but if I'd added an addendum to the
first one then this would probably have been ignored.
This problem affects a ContextMenu attached to a NotifyIcon object. I don't
get the problem with context menus attached to list boxes etc.
Ive also seen a noticeable slow down in speed when the menu attempts to hide
after the problem occurs.
When I build a dynamic submenu on the first time round, it shows a nice...

My app has a notify icon in the systray. I want the left mouse click to
initiate a menu, and a right-mouse click to do something else. Normally,
for a button, I would listen to MouseDown and if I need to display the
menu, I would contextMenu.Show(buttonCtrl, new Point(0)). But I can't do
this for a notifyIcon because notifyIcons aren't controls. How can I
display a contextMenu where the cursor is by command only?

I have created a Windows Service that shows a notifyicon in the system tray.
I have also created a context menu for the notifyicon and implemented the
notifyicons click event.
The notifyicon does appears correctly in the system tray while the service
is running but the context menu does not pop up when the icon is right
clicked. Nor does the click event fire when the icon is clicked.
Any suggestions?

nothing happens, but the menu shows up the second time i click it. it
only seems to display the menu every-other click. makes no sense to
me.
I have no idea why, any help...

I have a program which puts an icon in the notification area and has a menu associated with it available by right clicking on the icon. I want the menu items to be selected by single left clicks but I also want the user to be able to single left click on the icon itself to do some other functionality.
Here's the problem - the single click on the menu first fires the notifyicon1_click() routine and then the menuitem1_click() routine. How do I...

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:

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,...
