andrewduckerI hit a mental block at the start of last week, dealing with delegates and events. It literally made no sense to me, no matter how much I stared at the description/examples.
So, deciding that it must make sense or it wouldn't be in there, I decided to keep re-reading the book until it did make sense. I re-read the whole chapter every day, and after 3 days suddenly delegates made sense. After 5 days the way that events worked slotted into place too. It's a marvel to me that the brain can keep on processing things until suddenly they appear out of nowhere - I now can't see where the problem was, the examples now look perfectly simple and the functionality seems obvious.
Following on from that, I played around with web services last night. Getting a simple service up and running was a matter or moments, and writing a form that passed information into the web service and displayed the response took only another ten minutes. I'm very impressed - I wish I'd had this technology a few years ago.
Of course, I then passed the form over to Nathan to see if it would work over the internet, but he seemed to be having all sorts of problems with routing, so I went to bed. Hopefully I'll get the chance to play tonight.

Date: 2003-07-09 04:47 am (UTC)The += syntax was a giveaway, actually. It pointed out to me that when you connected a delegate to an event you were literally adding it to something.
So when you trigger an event, it goes through the list of attached methods and calls each of them in turn. Nice and simple.

Date: 2003-07-09 04:36 am (UTC)then 2 mins later, everything was up again, and all i did was cry on the keyboard...
but the security setting are still winging at me from the form you sent.. but as i sadi, that is likly to be simbas .net security settings...
however, it will be there default settings, so your program sets off default settings, and I have run other .net stuff ion this box...
maybe it prefers all data to be sent with a soap wrapper, isn't that somthing to do with the security bit????

...
nowe there is an idea.. the crap they put on the back of cerial packets..
Hands up all tohose techs that would buy a type of cerial that had wee descriptions of certain technologies on the back.. sorta of byte ( bite ) sized intros to somthing...
just think, we may even get more non techs interested in technology...

It's the SOAP request/response that's being called by the program I sent you.
