sender

I have been able to successfully cast video to a Chromecast and have the option let the video play when disconnecting and it all works great. However, if I choose to quit the application and let the video continue playing and then try to re-join the currently playing session and try to use the RemoteMediaPlayer to control the video I am getting: "java.lang.IllegalStateException: No current media session". Just as a background, I am saving the route id and session id on the initial connect into preferences and am able to successfully call "Cast.CastApi.joinApplication" and when in the onResult

for this app i'm following this example: http://pipoltek.blogspot.com/2008/02/sending-mail-using-gmail-smtp-server.html I can send emails, it looks good.....but i want to modify the sender email using this: MimeMessage msg = new MimeMessage(mailSession); msg.setFrom(new InternetAddress("baba-jaga@gmail.com")); baba-jaga@gmail.com is dummy E-Mail, is not mine :) When t use setFrom , i recive the email from this email, which i use to authenticate. Is the authentication the reason, which disable the setFrom method? I need to change the "from" email, because i want, that the recipient send me an

I'm confused as to the purpose of the sender parameter in Winform controls, for example: Private Sub Form1_Load(sender As System.Object, e As System.EventArgs) Handles MyBase.Load End Sub I understand i can verify what sender holds by doing something as so: If TypeOf sender Is Label Then 'Execute some code... End If But is there a good reason that sender is included in every single control when it generates the sub-routine for me? In other words, i double click on a Form and i get the Private Sub form_load (sender....) and e As System.EventArg s. What are some common usage of these two

I'm trying to create multiple buttons with a for loop, but I'm having problems using the (sender:) function. I have the following code func setUpButtons(){ for i in 1...3 { let btn: UIButton = UIButton(frame: CGRect(x: 100, y: 100, width: 75, height: 100)) btn.center = CGPoint(x: 20 + 100.0 * CGFloat(i), y: 200) btn.backgroundColor = UIColor.green btn.setTitle("Click Me", for: UIControlState.normal) btn.addTarget(self, action: Selector(("buttonAction:")), for: UIControlEvents.touchUpInside) btn.tag = i self.view.addSubview(btn) } } func buttonAction(sender: UIButton!) { let btnsendtag:

So I have a large UIButton , it is a UIButtonTypeCustom , and the button target is called for UIControlEventTouchUpInside . My question is how can I determine where in the UIButton the touch occured. I want this info so I can display a popup from the touch location. Here is what I've tried: UITouch *theTouch = [touches anyObject]; CGPoint where = [theTouch locationInView:self]; NSLog(@" touch at (%3.2f, %3.2f)", where.x, where.y); and various other iterations. The button's target method get info from it via the sender : UIButton *button = sender; So is there any way I could use something like:

In some IBAction I saw: - (IBAction)pushButton:(id)sender; This (id)sender when do I use it? (id)sender is the object which sent the message to that selector. Code example: - (IBAction)submitButton:(id)sender { UIButton *button = (UIButton *)sender; [button setEnabled:NO]; [button setTitle:@"foo" forState:UIControlStateDisabled]; } Ahmad Kayyali Matt Galloway described the meaning of (id) sender in actions on the iPhone Dev SDK forums thusly: (id)sender is the object which sent the message to that selector. It's like in the delegate functions where you have the control passed in to the
