notifyicon

问题 I just found out that there are 4 similarly names events for NotifyIcon named Click , DoubleClick , MouseClick and MouseDoubleClick . The description text for them says Occurs when the component is (double-)clicked [with mouse]. But what else can you click elements with except mouse? I tried clicking it with mouse and pressing Enter after some tricky selection stuff with arrow keys and tabbing. Clicking with mouse fires both events, but pressing Enter only fires the Click event. What other

问题 I have built an application that has a Notification Area Icon, which when clicked brings up a form that is designed for a single click, after which the user can then return to what they where doing before hand. Currently, I am using this.Hide() to remove the form (either when the desired event in the form occurs, or when the form is Deactivated ), but when I do, Windows sets the users focus to the Task Bar. How can I get it to return the Users focus to the Window they where on before clicking

问题 How can I animate the tray icon while the main application is processing? I already tried the suggestion here, but the icon does not animate during process. I also tried putting the animation in a separate thread but still no luck. 回答1: There's a very good example of an SystemTrayNotifyIcon with Event Generator over at the CodeProject .
