Question

When using flash, I was able to get to the focus of an event by accessing the event’s “target” attribute.

so if I remember, it was something similar to.

button1.addEventListener(mouse_click, doSomething);

doSomething(e: Event){
    e.target.size = 50000;
}

And I’m looking for the equivalent in VB.

If you can give me it’s common name across all languages, I’d be doubly grateful. I don’t quite know what to search for aside from “event.target VB.net equivalent, and that’s not returning anything.

Thanks in advance.

edit: for those new to flash. By focus, I mean the physical object that was clicked on. So the example given would be accessing the clicked button’s size.

Got it!

http://msdn.microsoft.com/en-us/library/system.web.ui.webcontrols.button.onclick.aspx#Y0

    Sub GreetingBtn_Click(ByVal sender As Object, ByVal e As EventArgs)
        'When the button is clicked,
        'change the button text, and disable it.

        Dim clickedButton As Button = sender
        clickedButton.Text = "...button clicked..."
        clickedButton.Enabled = False
    End Sub

The first parameter (sender by default) references the focused object. You can access it as you would any other normal variable, but it’s information won’t appear in the auto complete list unless you set it “As” that specific data type.

So I ended up with this

    Private Sub nw_btn_Click(ByVal sender As System.Windows.Forms.Button, ByVal e AsSystem.EventArgs) Handles nw_btn.Click
        sender.Hide()
    End Sub
