Suppose you have a button on a form that counts to 1000 in a textbox and then clears it. If I quickly click the button five times (in runtime) the Click event handler will be called 5 times and I will see the count to 1000 five times. Is it possible to disable other clicks on that button while the first click is counting? Note: Disab...
I am developing a heavily AJAX-based web app in JQuery that includes many GUI components. There are some application states that affect all GUI components. E.g. while an AJAX request is executed, I want my toolbar buttons to "freeze" and not trigger any click events until the request finished. The same applies to my slider control and s...
I am looking for a tunneling Button.Click event. The ButtonBase.Click event is bubbling and therefore the root can handle the event only after the action that was registered for that button already occurred (too late for what I need). I need the counterpart "preview" event, so that I can handle the event before the event that is registe...

Hi, I've got a rather lengthy question I'm afraid. I'm fairly new to ASP.NET so please bear with me. I have built a control for an ASP.NET page that lists a number of options. Each option has two clickable areas (call them buttons for the sake of simplicity). One to select the option and one to hide the option. protected void Page_Loa...
I tried the following, yet the button still has a white background: self.button = gtk.CheckButton() self.button.modify_fg(gtk.STATE_NORMAL, gtk.gdk.Color(65535,0,0)) self.button.modify_bg(gtk.STATE_NORMAL, gtk.gdk.Color(65535,0,0)) self.button.modify_fg(gtk.STATE_ACTIVE, gtk.gdk.Color(65535,0,0)) self.button.modify_b...
I'm calling the first function below to bind the second function to the onClick event. The strange thing is that calling the first function results in firing the second function. The LinkName parameter in the first function is a name of a table td element - probably not relevant. function EnableExpand(LinkName, i) { $(LinkName).ad...
Once upon a time I bumped into Introduction to Indy article and can't stop thinking about blocking vs non-blocking IO ever since then. Looking for some good articles describing what are pros and cons of blocking IO and non-blocking IO and how to design your application in each case to get natural, easy to understand and easy to maintain...
Hey, I am looking for a specific custom control. I am drawing some rectangles to my picture box, now I would like to display a tooltip when someone moves his mouse to one of the rectangles, so a hover rectangle-hover event. Does this sound doable at all? If yes, is there anyone that has made such a control already? If no, how would I go...

Recently I have been debating on the best way to handle communication up the chain in n-tier architecture. Currently the methods I am doing is throwing and handling exceptions between layers for errors, and using events/delegates for other communication (to update progress bars and such). Are these the best way or is there another metho...
how could I do that? I want to catch these events and see what's going on in my whole application. Must I subclass UIApplication for that? UIControl calls this method when an event occurs. It seems like if I subclass UIControl, there won't be a point where I could stick my nose deeper into the details of an event. I can just specify tho...
Hi I have a peculiar problem here and I can't by my life figure out what the solution is. Note that the following code is not dynamically created, but just immediately in my aspx file. <button type="button" runat="server" id="btnSubmit" OnServerClick="btnSubmit_Click" onclick="return confirm('Sure?');"> Submit </button> This wo...

I'm sure that i'm just not understanding something fundamental about events and/or delegates in C#, but why can't i do the Boolean tests in this code sample: public class UseSomeEventBase { public delegate void SomeEventHandler(object sender, EventArgs e); public event SomeEventHandler SomeEvent; protected void OnSomeEvent(E...
I have a thread running that delegates out some tasks. When a single task is complete, an event is raised saying that it has completed. These tasks need to be run in a specific order and need to wait for the previous task to finish. How can I make the thread wait until it receives the "task completed" event? (Aside from the obvious event...
Hi I recently started digging into C# but I can't by my life figure out how delegates work when implementing the observer/observable pattern in the language. Could someone give me a super-simple example of how it is done? I have googled this, but all of the examples I found were either too problem-specific or too "bloated". ...
I am creating a contextmenu that should contain a listing of all folders, subfolders, and files in a chosen folder. I want the menu to open the files and folders when they are clicked, but the click event doesn't register if the menuitem has subitems. void Foo(string Title) { MenuItem = new MenuItem(Title); MenuItem.Click += new...
