Is it possible to disable animation when minimizing / restoring window?
When I click minimize button in my Windows Forms application, I don't want it to perform the classic Windows minimize animation (window going down to taskbar). As far as I know, there's no Minimize event, I can just use Resize, but I have no clue how to detect if I clicked minimize button. I tried to use if ( WindowState = FormWindowSta...
Why won't my LinkButton inside a GridView raise its OnClick event?
I have a LinkButton inside a GridView (via an TemplateField). No matter what I try, the LinkButton will not invoke its event handler. I have tried both: A traditional event handler ("OnClick") A OnRowCommand event handler at the GridView level. In both cases, I've debugged and it doesn't even catch the event handler. If I move the...
Parent App access vs Events in Flex Modules
Inspired by this Flex question, is it seen as better practice to dispatch an event back to the parent app, as opposed to calling a method on the instance of the parent app, from within a module? To me it seems that the module shouldn't know what methods are available at the parent, as such approach leads to tight coupling. Thoughts? ...
Unable to refresh tree control with new branches from successful RemoteObject call
I'm trying to populate a mx:tree component with values that I'm getting from BlazeDS. The returned data from BlazeDS is fine - it's an ArrayCollection of Folder value objects. I've been instructed to use Cairngorm for this project. I'm pretty new to Flex and Cairngorm. According to the limited documentation that I've read online I shoul...

Is there a Dependency Injection-like pattern for wiring together Subjects and Observers?
A Subject-Observer relationship isn't a dependency relationship: Observers don't need Subjects in order to exist, and vice versa. Yet the "wiring together" of publishers and subscribers is strongly reminiscent of Dependency Injection. My shoot-'em-up game makes extensive use of the Observer Pattern. For example: A controller object spa...

[object design]Plenty of timed events to synchronize. How to ? :-)
Hi folks ! I'm trying to design an application (in C++ but that doesn't matter I guess, anything object-oriented would work the same) which has to synchronize a bunch of events together.

How to propogate Swing events from a inner component to a container?
Hello, I created a component based on a JPanel that contains a textfield and a checkbox. Since I use it as component and put it around in other panels I'd like to be able to set a KeyPressed event for the panel.

How to tell if a web page is being exited/unloaded via flash versus via normal HTML
Hi, I have a flash app, that redirects to another page. I'd love to trap any other window unload event (clicking links / submitting forms) and warn the user they'll lose their progress in the Flash app. However, I can't find any way to tell that the click/change of URL/window unload was triggered by Flash vs being triggered by a normal ...

I have a Windows.Forms app with a ListBox populated with Account objects. When the user selects an Account from the list I attach an EventHandler responsible for updating the selected Account transactions in the event that there's any new ones while the user is looking. private void listBox1_SelectedIndexChanged(object sender, EventArg...

Restricting asynchronous events to the calling object
Hi folks, in my C#-Silverlight-3-Application, I have created a class, that is doing some calculations that are used in different parts of my program. This class needs data from a database, so it calls a WCF-Service to get the data. The structure of the class looks like this: public class ConsumptionCalculation { // Declare the event...
.NET (C#) events - custom EventArgs question

I started creating a separate EventArgs-based class for each custom event, to package the necessary data for the event. In hind-sight though, I realize that most ...
JQuery events don't work with ASP.NET MVC Partial Views
I am trying to get JQuery events to work with partial views in ASP.NET MVC. However, after you load a partial view through Ajax, JQuery seems not able to fire events for any of the elements in the partial view. I suspect that this issue will also happen if you are using other frameworks or JavaScript libraries to load partial html code w...

Why the subtle cross-browser differences in Event Object.
The following declaration at the window level: var event; // for IE var event = "anything"; // for Chrome will destroy the event object as used here: <div onMouseOver = "alert(event.type);">Mouseover Div</div> Firefox does not seem phased by either declaration. I realize that declaring a variable with the name "eve...
