  • Whats the difference between Sender, From and Return-Path?
    So, the sender header is set to [email protected], to indicate the From header doesn't indicate who actually submitted the message In this case, if the message cannot be sent, it's probably better for the agent to receive the non-delivery report, and so Return-Path would also be set to [email protected] so that any delivery reports go to it
  • MailMessage, difference between Sender and From properties

    (object sender, XXArgs e) where XXArgs is a class that inherits from EventArgs sender is, well, the sender of the event In your example, if you click on a button, the button will fire the event using its own instance reference (this) for the sender parameter (so sender is a reference to your button) This is useful because you don't need to

  • Cast sender object in event handler using GetType (). Name
    I know this is a very old post but in Framework 4 you can cast the sender as a Control: Control cntrl = (Control)sender; cntrl Text = "This is a " + sender GetType() ToString(); Note you are only able to reference controls that all of the different controls have in common (ie Text)

  • In a C# event handler, why must the sender parameter be an object?
    Events are covariant: you can pass a more specific type (say MyType) to an object sender param, but if it has an explicit type (say ApiType sender) then you can't pass MyType in There are reasons you might want that restriction, and it isn't bad practice, but the OP was asking why object sender was a common pattern used as default by Microsoft
