Create Pocket PC application.
:)
I am reminded of a passage from the "naturalist's" bible, The Earth for Sam, where the author asked the question "What if everybody was a barber?".

I forget the point - it was something along the variety of life theme. Okay you can create a pocket PC application. Now first tell me - does the pocket PC download the 23MB framework?

What kind of applications will the PPC market "pay" for? What's the competition? Whats the margin? From my point of view a lot of that stuff is give aways unless you have a relation with the platform vendor.

You may have an expertise I am not aware of and maybe be very compeditive in that market. I know that Nick and Mike have done some nifty things and I would not be surprised.

Is that space is crowded? Can you compete with high talent low cost Eurasians?

It is an unknown to me. If I had an idea - I would probably hire rather than implement.

So what kind of NET apps are they - games - currency pricers - pornsite connections:)

I seek refuge in the "unusual" business rules market. Only near dead would trod those merky waters.

Do you know what Javascript is?
Not enough to call myself an expert!:)
But I am beginning to learn some.

DOM seems to open a bunch of oppertunities. With DOM a lot of the stuff legacy developers relied on JSP and Java (class) to accomplished seem to be addressable with a client DOM instance. And DHTML - though not quite W3C - presents oppertunities as well. We could - almost - build apps with just a browser, DHTML, JavaScript and XML. I like DHTML - I wish we similar features in VFP. It took me a while to understand that changing the "class" rather than a "property" of a document element was the way behaviors are affected.

Here is some stuff I do with JS. It aint much - but for a guy who grew up being warned by his mother to stay away from "wheel barrows" because they are "machinery" - it's a start. It's an interesting paradigm but I don't know enough to make any claims.

this.isInitialized =

        {
        this.SetError(varGeneralGetFailure);
        }
     return mInitializedState;
     }
this.SetError =
     function SetError(iCode)
     {
     window.MainFrame.Collection.last_code.value=iCode;
     }
}
Here's some code I googled on "really simple javascript tree":-)

          {
          node.childNodes.item(0).src = "plus.gif";
          }
       }
       node.nextSibling.style.display = 'none';
   }
}
Any good book recomendations or urls appreciated. I am build TVs with JS and there are DHTML listviews that are every bit as cool as some of the stuff we do with VFP. I got a lot more to learn - for sure!
Imagination is more important than knowledge
