  • Programming a windows service

    - by xarzu
    I have started prgramming a windows service. I have added a notify icon from the toolbox. It has the small notify icon that appears in the systray as a member of those icons. It works so far. So far I have a blank form. I have used the DoubleClick for the notifyIcon to bring up the form (I will use the form for something later). Now I have a list of things I want to accomplish to make this work like a true windows service. First of all, if possible, I owuld like to remove the maximize and cancel button on the form. Most windos service apps that I have seen offer the ability to close the app by right-mouse-button clicking on the notify icon which brings up a menu of options. I see in the properties of the form under Misc there is an CancelButton. But I do not see how do deactivate it. In the Properties of the forum I see under Window Style there is a ControlBox option that, if I turn to false, all three buttons, (minimize, maximize and cancel) go away. These are not what i am looking for. I would not like the option for them to resize, maximize or close the form here. I suspect people will close the box intending to make the box go away while still wanting the app to run. Under the "Focus" caption in Properties, there id "Deactivate". I have created my own event/method/function for this and in debug I noticed that when you click on the x-box in the upper right corner, this function is called. The problem is that after the function is over, the app closes anyway. How do I over-ride this function? Secondly, how do you catch the right button click event on the notify icon in the systray? I can see how to create events for "Click" and "MouseClick" etc. but how so I determine which button was click? Using the right buton click is how such programs know when to pull up a menu. So I would like to know how to do this as well.

  • Help understanding Cairngorm Event in Flex

    - by tusay
    Hi, I was going through this article by David Tucker (http://www.davidtucker.net/2007/10/29/cairngorm-part-3/) in which he talks about Cairngorm Events. There are two things that I want to ask in this- What is the significance of calling the constructor of the parent class with the event arg? super(LOGIN) in the example Why do you need to overrride the clone method? Understanding these things will give me a better insight into the way things are done with Cairngorm. Thanks

  • Swing verify code on event dispatch thread at runtime

    - by Jeff Storey
    Are there any libraries that instrument code to verify that methods called on swing components are called on the event dispatch thread? It probably wouldn't be too difficult to write some basic code for doing this, but I'm sure there are edge cases and whatnot that other people have handled. I'm looking for this at runtime though, not for unit tests. thanks, Jeff

  • So many ways to bind an event

    - by XGreen
    There are various ways to bind events to elements in jquery .click , .bind, .live, .delegate, saving events data in .data etc which is the most superior method among these and why? wouldn't a single pattern like this be more beneficial? $('selector').bind({ event: 'click mouseover ...', keepAlive: (true, false, ...), trigfunction: (function() { // I run for click }, function() { // i run for mouseover }, function() { ///... }) });
