Request for comments on C-Structs to MC structs...
Hi gals and guys, If some of you are interested, i've mentioned earlier in the meta-time-space continuum that I was porting C++ programs to Metacard. In these programs I have extensive struct variables to port, and some include arrays of structs inside of structs, etc... Big mess I got into! Using properties doesn't help and creating the structs/pointer space inside a string variable seems overkill... Before I go bananas (or meta-tutti-fruity), I'd like to ask if anyone has tried nesting arrays into arrays? put abunchoflinesofdata into test[x] -- this works put anotherbunch into test2[x] -- this also will work put test[x] into test[y] put test2[x] into test[y+1] will this work and be reliable? Limits known?

RE: Request for comments on C-Structs to MC structs...
Richard,
Thanks but there is a speed issue here... Accessing data in properties of
objects
is/or must be just as slow as accessing a field... Which is why im not using
groups
of fields to re-create these structures...
It's the same reason im not using item x of line y of Zcontainer.
it's plain simpler and faster to use 2 items over thousands of lines than
100's of items across 2 lines...
Arrays seem to be the last solution before going back to C
What would be nice is to have multi-dimensional arrays like in C, basic
X[a][b][c]...[z]
or
assigning properties to containers
put x into the color of myobject[x]
Scott? Feasible?
Meanwhile, my solution is the following:
X[a][b][c]...[z] = x[a(i^3)+b(i^2)+c(i^1)+d(i^0)]...[z] where {a,b..,z} is a
polynomial serie sigma((x(sub base i)) ^ (i-1))
and where i is the max(number of elements in any dimension)
the only danger is passing the limit of array elements too easily...
(2^54)-1...
repeat with l = 1 to NUM_layers
repeat with i = 1 to Net_Layer[l]
repeat with j = 0 to net_layer_units[l-1]
put l*100+i*10+j into va -- virtual array dimension
put RandomEqualREAL(-0.5, 0.5) into Net_Layer_Weight[va]
end repeat
end repeat
end repeat
any better ideas are welcome! Using nuclear fusion power to start a light
bulb!

Remember that you can store and retrieve arrays from objects by setting the
properties of the current propertyset of the object to an array:
-- Create an array:
put hello world into tMyArray[1]
--
-- Tell MC which propertyset to work with:
set the propertyset of stack storage to ArrayData
--
-- Set all of the key-value pairs of the storage object to
-- the key-value pairs of the array:
set the properties of stack storage to tArrayData

But morever, you only need to do it once during initialization to read the data from an object into an array, and again while saving to store the array in the object. -- Richard Gaskin Fourth World Media Corporation Developer of WebMerge 2.0: Publish any database on any site ___ [EMAIL PROTECTED] http://www.FourthWorld.com Tel: 323-225-3717 AIM: FourthWorldInc ___ metacard mailing list [EMAIL PROTECTED] http://lists.runrev.com/mailman/listinfo/metacard
Re: New on this list but not a newbie
Hey Alain - Good to see you here. ... I have been doing this web stuff for about 7 years now, and I've tried countless pure-Web solutions, and still none of the Web stuff compares to the interactivity and performance that can be achieved with *real* software. Particularly software like MetaCard which is as multi-platform as any existing web-browser; for playback (like the Web) as well as authoring (unlike the Web); client-side as well as server-side (just like Java but incomparably simpler). Web pages, even with JavaScript in them, are severely limited in terms of client-side interactivity. You cannot easily allow the users to move things around, do drag-and-drop stuff, and so on. ... The point of all of this is that I am trying to convince the lab I work for to opt for an xCard approach (breakthru) instead of the web-only approach (conformity mediocrity) that so many are resorting to now. My presentations on this issue have had a definite impact on my colleagues, but they are still hesitating a bit because not-conforming to what everyone is doing is perceived as risky. Everything worth doing has some element of risk, but any experienced business person shoud appreciate the relationship between risk and reward. With MetaCard you're almost cheating: you can build things so quickly that the cost-benefit analysis is nearly always favorable over alternatives, and that's before you consider the usability benefits of doing anything but browsing outside of the browser's limitations.

Re: New on this list but not a newbie
There is no breakthru in using Metacard for your project just a more efficient spending of time and energy but I know what you mean. It's not a breakthru for you or for me, given that we have been using one or more xCards for years now. It is a breakthru though, when compared to what web-browsing internauts are commonly settling for. It's a breakthru for the lab I work for, furthermore, because they didn't even know that such a thing exists. Relativity man! ;-) Alain __ Do you Yahoo!?
