Withevents VS Handles

[michaelrawi]

Supposed I want to create a button, and only need it's click event. Which one should I use:

 

dim withevents button1 as windows.forms.button

 

or

 

dim button1 as windows.forms.button
addhandler button1.click,addresof button1_click

 

Which is the best and why?

 

Thanks in advance

Oh, I've look some of you have a fancy code tag with visual studio style / color. How can I do that ?

To make your VB code pretty, use the

 tags, and to make C# code look pretty use [CS] tags.

 

As for the difference between WithEvents and AddHandler, the only difference is that WithEvents does the wiring automatically. That means that if you declare a WithEvents variable, every time you assign an object to the variable, the handlers are automatically attatched and every time you remove an object from a variable (assign another object or assign Nothing to the variable) the handlers are removed.

 

AddHandler/RemoveHandler gives you more control over how event handlers at attatched and removed, but if WithEvents suits your needs then that is probably your best bet because it requires a smaller amount of clearer code (but is harder to port to other languages).

 

Both methods basically compile down to the same thing.
