Is there a way to attach an event to a foreign / separate window from an .NET process that when the foreign window is closed or is about to close my application can be notified? I found this http://msdn.microsoft.com/en-us/library/ms229658.aspx But that seems to only be for the .NET compact framework. I am looking for something using t...
INotifyPropertyChanged is fairly self explanatory and I think I'm clear on when to raise that one (i.e. when I've finished updating the values). If I implement INotifyPropertyChanging I'm tending to raise the event as soon as I enter the setter or other method that changes the objects state and then continue with any guards and validatio...
Environment: VS2008 (ATL), Borland Developer Studio 2006. Hello all. I'm having some troubles with ActiveX control events. Here is a brief description of my app architecture: There is an inproc COM server which contains STA ActiveX control (aka control) and MTA COM object (aka object). Here is the IDL definition of the control an...
I have seen a few mentions of this idiom (including on SO): // Deliberately empty subscriber public event EventHandler AskQuestion = delegate {}; The upside is clear - it avoids the need to check for null before raising the event. However, I am keen to understand if there are any downsides. For example, is it something that is in wi...

I want to write some JavaScript that will change the onmousedown of a div at runtime. So on load a mouse down on the div will do one thing and if a JavaScript fuction is called a mouse down on the div will do something else. Is this possible? ...
Hello, I am writing a very specialized app in C# that floats as a mostly transparent window over the entire desktop. I want to be able to create and pass mouse events to applications behind mine, and have them appear to operate "normally", responding to those events. It would also be preferable if the window manager could respond. I am ...
I haven't found an answer elsewhere and this doesn't appear to have been asked yet on SO. When creating an event binding in wxPython, is it possible to pass additional arguments to the event? For example, this is the normal way: b = wx.Button(self, 10, "Default Button", (20, 20)) self.Bind(wx.EVT_BUTTON, self.OnClick, b) def On...
I'm working with a combobox in a Swing-based application, and I'm having a hard time figuring out what to do to differentiate between an ItemEvent that is generated from a user event vs one caused by the application. For instance, Lets say I have a combobox, 'combo' and I'm listening for itemStateChanged events with my ItemListener, 'l...
While simple, interface-driven event notification frameworks in Java have been around since pre-Cambrian times (e.g. java.beans.PropertyChangeSupport), it is becoming increasingly popular for frameworks to use annotation-driven event notification instead. For an example, see JBossCache 2.2. The listener class has its listener methods ...
I tried doing this: root.addEventListener("click", function () { navigateToURL(ClickURLRequest,"_self"); }); And it does add the event listener. I like using closures because they work well in this situation, however, removing the event listener requires a reference to the original function, and since I used an ano...
Hi, Does anyone know of crossbrowser equivalent of explicitOriginalTarget event parameter? This parameter is Mozilla specific and it gives me the element that caused the blur. Let's say i have a text input and a link on my page. Text input has the focus. If I click on the link, text input's blur event gives me the link element in Firefo...
I have a custom control that I created for my project. In this control there are several child controls like a Label, a PictureBox, and a LinkLabel. Other then the LinkLabel, I want the mouse over event currently on the parent control and have the control respond to the mouse over. The background color changes when you hover over the con...
Not sure what exactly is going on here, but seems like in .NET 1.1 an uninitialized event delegate can run without issues, but in .NET 2.0+ it causes a NullReferencException. Any ideas why. The code below will run fine without issues in 1.1, in 2.0 it gives a NullReferenceException. I'm curious why does it behave differently? What ch...
Is there a best practice when it comes to setting client side "onclick" events when using ASP.Net controls? Simply adding the onclick attribute results in a Visual Studio warning that onclick is not a valid attribute of that control. Adding it during the Page_Load event through codebehind works, but is less clear than I'd like. Are th...
I'm having some trouble with plain old JavaScript (no frameworks) in referencing my object in a callback function. function foo(id) { this.dom = document.getElementById(id); this.bar = 5; var self = this; this.dom.addEventListener("click", self.onclick, false); } foo.prototype = { onclick : function() { this...
I've been asked to find a way to send an alert to a blackberry when certain conditions are met on an Excel 2007 spreadsheet. The alert can be an SMS (preferred) or an email. The cell values are changing throughout the day from a DDE feed. What are the typical solutions that people use to solve this? ...
