properties

问题 I am currently using Visual Studio, and I don't know if this is a glitch or not, but when I go into the form properties, and show the events, there are two events called KeyDown and KeyUp . Now when I do the same for a PictureBox , it has way less events and no KeyDown and KeyUp events. Does the PictureBox support less events then other things? Is this a glitch? Screenshot of Form1 properties: Screenshot of PictureBox1 properties: 回答1: Its not a glitch. Its the way it is. You don't type in

问题 What is the cleanest way to define a class with a large number of properties, each of which calls the same setter function with a different parameter? Below is what I'm trying to achieve. Each of the three properties (red_LED etc) call the same TalkToHardware() function when they are set, but with a different address. As you can see, this works, but the class definition is long and unwieldy. It is also error prone. class Hardware_Controller(object): def __init__(self): self.red_LED_address =

问题 In classic ASP I have an object, call it bob . This then has a property called name , with let and get methods. I have a function as follows: sub append(byref a, b) a = a & b end sub This is simply to make it quicker to add text to a variable. I also have the same for prepend , just it is a = b & a . I know it would be simple to say bob.name = bob.name & "andy" , but I tried using the above functions and neither of them work. The way I am calling it is append bob.name, "andy" . Can anyone see
