Adding Class Event Handlers and Overrides

[Jonathan Wood]

I'm building a Web application but this question should be common to all C#
applications.

When I use a class, and I want to add event handlers or override base class
methods, how do I know the correct syntax for those methods?

In MFC, I can simply choose event handlers from a list and they are inserted
automatically with the correct signature. Similar deal with Visual Basic 6.
But I can't seem to find anything like this in C#.

Do I have to know the signature of every method I add or is there a hidden
feature for this somewhere? (Note: Double clicking a control is not an
option in this case as I'm currently trying to override a method in the base
class and/or finding out what methods are available in the base class.)

Are you using Visual Studio? It does this for you as you type. For example
with overrides, typing "override" will bring up all of the possible
overrides, for events typing the event handler you want then the += statement
will bring up the auto complete option. Make sure that the
Tools->Options->Text Editor->All Languages options have the "Parameter
Infomation" option checked.

Okay, thanks. I'm used to point and click but I guess I can type in override
and that seems to work okay.

Not sure the event tip helps me though because, just starting to move to
..NET, I don't really know what events are available. So I won't be typing
them in.

BTW, I notice the Class view tab is completely empty. In MFC, I can use that
to see what's what. Seems like that would be a nice addition to C#.

Thanks again.

When you are in Visual Studio and have an object, when you type the period
(.) you will get a list of all the methods and events so you can see what is
available to you, which is very handy.

BTW, I notice the Class view tab is completely empty. In MFC, I can use that
to see what's what. Seems like that would be a nice addition to C#.

The class view will show you all of the namespaces and types in your
project, it should not be empty. Not sure what you mean by "what's what" but
another useful window if you have Visual Studio 2005 (not the express
editions) is the "Code Definition Window" which gives you information about
types / methods etc as you click on them, which is really great, I use this
alot.

Hope you have fun in the .Net world, it is definitely worth learning.

Mark,

(.) you will get a list of all the methods and events so you can see what
is
available to you, which is very handy.

Yeah, I'm familiar with that--it's the same as with Visual Basic 6 and MFC.
But when there's no visual object associated with a class you're inheriting
from, I don't view that as much help.

The class view will show you all of the namespaces and types in your
project, it should not be empty.

Yeah, well, after several hours of trying to learn to work with ADO.NET,
it's no surprise. I could fill a book with what should be but is not. The
Class View is completely empty for me.

Not sure what you mean by "what's what" but
another useful window if you have Visual Studio 2005 (not the express
editions) is the "Code Definition Window" which gives you information
about
types / methods etc as you click on them, which is really great, I use
this
alot.

Hmmm... Hadn't seen that one before. Didn't seem to do much at first glance.
I'll play with it a little more.

Hope you have fun in the .Net world, it is definitely worth learning.

Yes, I'm not new to programming by any stretch. I do feel the .NET
technology for Web sites is cool. But it's not as accessible as some
previous MS languages and working through ADO.NET, in particular the
connections and security, etc. is a royal PITA.
Baaaaaaaarrrrrrrrfffffffff!!!

Thanks.
