I believe that your MouseLeftButtonDown handler is not called because the ListBox uses this event internally to fire its SelectionChanged event (with the thought being that in the vast majority of cases, SelectionChanged is all you need). That said, you have a couple of options. First, you could subscribe to the PreviewLeftButtonDown event instead. Most …
‘The’ answer (Read more below if you want to see how I got to this solution) Usage, given a control with a vanilla MouseDown event, and a specific EventHandler<ValueEventArgs> ValueEvent event: // for ‘vanilla’ events SetAnyHandler<Subscriber, MouseEventHandler, MouseEventArgs>( h => (o,e) => h(o,e), //don’t ask me, but it works*. h => control.MouseDown += h, h …
It is the same. The second is merely syntactic sugar for the first, and equality comparison is overloaded appropriately for delegate types: Two delegates of the same type with the same targets, methods, and invocation lists are considered equal. Source: MSDN, Delegate.Equality Operator
since I wasn’t able to find a ready-to-use solution, I’ve done a custom implementation based on Pieters (and Marks) suggestions (thanks!). Using the classes, you will be notified about any change in a deep object tree, this works for any INotifyPropertyChanged implementing Types and INotifyCollectionChanged* implementing collections (Obviously, I’m using the ObservableCollection for that). I …
Put your on disconnect code inside your on connect block and edit it a bit like so: io.sockets.on(‘connection’, function (socket) { count++; io.sockets.emit(‘count’, { number: count }); socket.on(‘disconnect’, function () { console.log(‘DISCONNESSO!!! ‘); count–; io.sockets.emit(‘count’, { number: count }); }); }); This way you’re detecting when a specific socket (specifically the socket you pass to …
To simplify Simon’s code a bit, you could use the built in generic Action delegate. It saves peppering your code with a bunch of delegate types you don’t really need. Also, in .NET 3.5 they added a params parameter to the Invoke method so you don’t have to define a temporary array. void SomethingHappened(object sender, …
The other solutions use innerHTML, which won’t always work in XHTML. They also only clear document.body (anything in the <head> is still present). Here is a solution that uses the DOM: var frame = document.getElementById(“myFrame”), frameDoc = frame.contentDocument || frame.contentWindow.document; frameDoc.removeChild(frameDoc.documentElement); This solution uses innerHTML: var frame = document.getElementById(“myFrame”), frameDoc = frame.contentDocument || frame.contentWindow.document; frameDoc.documentElement.innerHTML …
SystemEvents.PowerModeChanged += OnPowerChange; private void OnPowerChange(object s, PowerModeChangedEventArgs e) { switch ( e.Mode ) { case PowerModes.Resume: break; case PowerModes.Suspend: break; } } You should probably read this: http://msdn.microsoft.com/en-us/library/microsoft.win32.systemevents.powermodechanged.aspx
You can set event_scheduler=ON in my.ini or my.cnf file, then restart your server for the setting to take effect. Once set event_scheduler will always remain ON no matter whether your server restarts.
