  • How to pass Button.Click into a function?

    - by Achilles
    I have a function that adds eventhandlers to control events. Right now I have several overloads that add events to different types of controls: Public Sub AddEventHandler(Button, ButtonEvent) 'adds event handling for Button.Click public Sub AddEventHandler(LinkButton, ButtonEvent)'adds event handling for LinkButton.Click The problem is I want to write a function that is more robust like: Public sub AddEventHandler(Control, EventToHandle, ControlEvent) where EventToHandle is the parameter representing Button.Click or whatever event that Button has associated with it. Any suggestions guys? Thanks!

  • Facebook data collection ethical issues

    - by the_great_monkey
    If I have a Facebook app, and my users agree to allow my app to access their information, photos, friends, etc, is it ethical to grab their information when they log in, and then saving it in memory so that the next time he goes to my app, it can load faster? If so, what about when the user logged off? Is the right thing to do to is to delete all the cached information and photos that the user provided? Has Facebook got any way to detect that we're doing this (saving their information, etc)?

    - by youwhut
    I am performing actions on the page during WatiN tests. What is the neatest method for asserting certain elements are where they should be by evaluating the HTML source? I am scraping the source but looking for a clean way to navigate the tags pulled back. UPDATE: Right now I am thinking about grabbing certain elements within HTML source using regular expressions and then analysing that to see if other elements exist within. Other thoughts appreciated.
