I noticed on the website that there is an external collection for MacOS and
MacOSX.. is there something like that available for Windows?

Re: PreOpenStack confusion

[Sarah Reichelt]

I don't know how to stop it happening when you return to the stack, but the
way I stop it happening when opening other stacks is to give the other
stacks empty handlers of the same name.

If the substacks have in their scripts:
on preOpenStack
end preOpenStack

with no "pass", then they won't try & run your main stacks preOpenStack
handler.

I hope someone else has a neat solution to problem (ii).

Cheers,
Sarah

Getting a card's position in a group

[Devin Asay]

Hi all,

I can easily go to a specific card relative to its position in a group:

   go card 3 of group "myGroup"

Is there a simple way to return a card's position in the group?

   similar to: get the number of this card  -- returns the card's 
ordinal position in the stack

   but what I want is:  get the number of this card in group "myGroup"
   so that it returns the ordinal position within the group.

The information must exist somewhere because I can go to a specific 
card within the group.  But how to access it when I'm alread on that 
card?

You could write a custom function to do this in one line.  This is already

 John...

As an aside, since you have to establish a current position in the db stack
before adding a new record anyway, you can build your db stack in "record
key" or some logical format by creating each new card between the two cards
where it would be ordered.  For example, my db stacks create records in
order by record type and key.  Having filed the records in order
originally, one can then support relative (ie: previous record, next
record) access as well as keyed access.

Hi John,

The create command places the new card after the current card, not the card
that receives the command.

I believe if you go to the last card of stack2 (locking the screen if
necessary) before sending the create command, you will find your new card
and it's data in the right place every time.

Re: RealBasic is real basic

[Rob Cozens]

Revolution is the ONLY environment that is closest to the promise of 'write once, run anywhere'.

John, et al:

For history's sake, let me point out that there actually once was a "write once run anywhere environment": the UCSD-p operating system & UCSD PASCAL.  It ran on a wide range of computers from Dec minicomputers to Radio Shack TRS-80s in the 1970s.  

Like RR, it was a runtime (ie: interpreted) environment; unlike RR it included its own O/S (which eliminates many cross-platform issues such as different sizes of text).  Like RR it included a (reasonably good for the time) debugger and the ability to resolve routine libraries at runtime (ie: 'start using" in Transcript syntax).

Several days ago someone suggested there might be a slight performance hit running a RunRev stack created on a Mac on a Windows box because the Intel and Motorola CPU chips read each word in reverse order.  In 1986 I spent two frantic weeks trying to find the cause of a dramatic (40-60%) performance degredation of our corporate computer (a multi-user Motorola 68xxx CPU).  It turned out that the last O/S upgrade sent me had been created for an Intel 808x!  Everything worked just fine; but the operating system was wasting an enormous amount of time reversing the byte sex of every word it read.

Watching UCSD-p System lose out to MS/DOS when the IBM PCs originally were introduced, I learned first hand that a technically and functionally superior product can fail

a. when competing against an inferior product backed by big advertising $, or

b. when corporate management doesn't understand the product or the market.

In this case Microsoft offered MS/DOS for $40 while Softech Microsystems charged over $400 for the IBM PC implementation of the p-System.

In my book of computer history, Softech's IBM PC pricing strategy and Apple Executives' inability to "get" what HyperCard was all about rank right up there with Xerox's unappreciation of the PARC GUI.

The article is as current about REALBasic as it is about Revolution - both
products have been revised somewhat since it was written.  For example, on
the Revolution side, the database features - a key part of Revolution - were
not even shipping when the article was written.  No doubt there will be a
revision of the article at some point to cover the new features in both.

But the main points of the article were not about individual features, and
thus are not out of date.  The main point is that Revolution is simply a
more productive environment to work in.  You write less code, can then
execute it live immediately, and can edit and debug on all platforms.  Of
course if there is a particular feature that one or other product has that
the other doesn't and no external is available that will determine your
choice.  Otherwise, Revolution offers a lot more productivity on more
platforms.  And contrary to popular belief, Revolution is a compiled
language, which has similar performance to REALBasic.  Sure there are some
areas one or other as faster, but they are in the same ballpark.

> Please also check out the numerous

The fact that REALBasic has been shipping longer does mean that there are
currently more reviews of it available.  However, Revolution is also making
its way steadily into the mainstream press, and our first independent
review, by the UK's leading Mac magazine, gave it a five out of five rating
and called it the "Holy grail of cross-platform software development".  A
good start...

RealBasic is real basic

[JohnRule]

Revolution is runtime (i.e. compile on the fly)...RealBasic is , well, real basic. 

  Programmers have been trapped in the paradigm of 'code/compile/test' for so long that they look at me as if I am from Mars when I mention the term 'runtime'. They don't believe me when I tell them that they can skip the 'compile' stage, and just test. AppleScript may do this, but that is 'Apple' on an 'Apple' platform only (yawn). Revolution is the ONLY environment that is closest to the promise of 'write once, run anywhere'. After trying Codewarrior Professional, and going through the Sun Java certification course to become intimate with Java, I can truly attest to this...everything else is 'real basic' at this point (and really counter-productive IMHO).

  Now all we need is Windows CE support...then we can take over the world. They didn't call it 'Revolution' for nothing!

Encrypt/decrypt

I thought I recalled seeing mention of encryption within Rev in a 
previous thread but a content search of the messages I have saved found 
nothing. How can you encrypt and decrypt data within Rev? Is there an 
intrinsic function (which I have not yet found) or do I resort to 
Applescript? This is no longer a stopper for what I am doing but I would 
like to know the answer.

Buffer on X vs. Classic

[cowhead]

I think this has already been discussed, but at the time I didn't quite
follow or pay attention.  Anyway,  I have this situation:

1.  a player is playing a quicktime movie (actually a GIF) with looping
2.  I move the player around while it is playing (using move relative)

In Mac classic, with the alwaysBuffer of the stack and player set to
true, the movement looks nice and smooth (although I think the player
pauses briefly during the move).

In contrast, with mac OSX, you must set the alwaysBuffer of the player
to false, or it disappears, at least briefly, during the move, giving a
choppy, blinky appearance.  With alwaysBuffer() set to false, the move
looks good as it does on classic. BUT:

3.  with always buffer set to false, a playing or paused player cannot
appear behind a field, even if the layer of the field is way over that
of the player.  I think this is true on both platforms.

So, why does the "alwaysBuffer" of a player work oppositely under X and
classic?  Bug?

Employee Database Tutorial "broken" on OS X?

[Dan Shafer]

Just finishing up going through the Rev tutorials preparatory to 
starting to really dive into this beast and I encounter a problem.

When I bring up the "Independent Study" tutorial stack which is the 
Employee Database example, a couple of weirdnesses develop.

First, there is a mongo button covering up the majority of the data 
entry fields. I can't for the life of me figure out what it is or why 
it's there but it sure makes the stack ugly and almost unusable.

Second, there's no place for pictures.

Third, the tutorial says we can use the images in the sub-folder in 
the tutorials folder using the "picture feature" but I'm darned if I 
can find that feature anywhere on the menu bars in the app.

Finally, if I have a few new employees defined and then I import from 
a text file, it clobbers all but the first employee I've added 
without so much as a by-your-leave or a confirmation dialog.

So is this stuff OS X-peculiar or have others seen this stuff?
