I'm working on a tutorial to build a media player in Silverlight and am trying to wire up an EventHandler
to the timer.Tick
event of a DispatchTimer
object so that the time of the video is synced with a Slider
object.
The sample code is in C# and I can't for the life of me figure out the proper syntax in VB.NET with RaiseEvent
and/or Handles
to wire up the event. Below is the relevant C# code. I'll include comments on where I'm getting stuck.
private DispatchTimer timer;
public Page()
{
//...
timer = new DispatchTimer();
timer.Interval = TimeSpan.FromMilliseconds(50);
timer.Tick += new EventHandler(timer_Tick); // <== I get stuck here b/c
// I can't do "timer.Tick += ..." in VB.NET
}
void timer_Tick(object sender, EventArgs e)
{
if (VideoElement.NaturalDuration.TimeSpan.TotalSeconds > 0)
{
sliderScrubber.Value = VideoElement.Position.TotalSeconds /
VideoElement.NaturalDuration.TimeSpan.TotalSeconds;
}
}
It is pronounced as Visual Basic . NET, which is an updated feature and version of Classic Visual Basic 6.0. It is pronounced as "C SHARP" language, that belongs to the C family.
The main difference between Visual Basic and Visual C++ is that Visual Basic is an Object Oriented Programming Language while Visual C++ is an Integrated Development Environment (IDE). Visual Basic is a user-friendly programming language developed by Microsoft.
With VB.NET, you can create applications that are fully object-oriented, similar to the ones created in other languages like C++, Java, or C#.
Though C# and VB.NET are syntactically very different, that is where the differences mostly end. Microsoft developed both of these languages to be part of the same . NET Framework development platform. They are both developed, managed, and supported by the same language development team at Microsoft.
Like this:
AddHandler timer.Tick, AddressOf timer_Tick
Alternatively,
Private WithEvents timer as DispatcherTimer
Sub timer_Tick(sender As Object, e As EventArgs) Handles timer.Tick
End Sub
