- Revolution 2.8 is free to users who had an active license as of its 
release on February 19, 2007, per the usual licensing arrangement.

- Revolution 2.9 will be free to anyone who had an active license as of 
February 1, 2006, or purchased any version after that date.

Thus, there are some customers for whom 2.9 will be free, but 2.8 is not.

The thing that comes to mind immediately for me is Vista's "ReadyBoost"

Re: [OFF] Input/Info Requested

Bill-

Here's my VB-to-xtalk cheat sheet. Hope you find something useful in
it. The formatting looks all wonky to me today for some reason. I'm
not sure why. Everything used to line up nicely, but now it all seems
staggered. Let me know if you have trouble with it and I'll try to
reformat it again into something more useful.

-- 
-Mark Wieder
 [EMAIL PROTECTED]Visual Basic-to-xTalk Cheat Sheet:

XTalk languages follow a natural-language approach. In general, statements are 
of the imperative form in which there is an implied second-person subject of 
the statement (you) and the verb is the first word of the line: "put value into 
container", "add 1 to someVariable", etc.

Thus the VB syntax in which some statements have an implied verb ("X=4" instead 
of "LET X=4") must be translated to xTalk syntax "put 4 into x".

lblTemperature.Text = 98.6  put 98.6 into field "lblTemperature"
xyz = xyz + 1   add 1 to xyz
let x = 3.14put 3.14 into x

In most cases a direct translation of VB to xTalk is not the best way to code 
any given problem. As with any programming language, there are many ways to 
accomplish any task. Direct translation will provide the fastest way to get a 
project converted, but from there out a rethinkng of the code will provide code 
that executes faster in fewer lines, is more readable and maintainable, and may 
offer new insights into how to solve a problem.

Arrays: Arrays in xTalk are associative - the index may be, but does not need 
to be, numeric in order to access array elements. The VB array syntax 
arrayName(index) is replaced by arrayName[index]. There is no VB equivalent for 
a non-numeric array index.

arrayName(4) = "hello"  put "hello" into arrayName[4]
put "hello" into 
arrayName["greeting"]
put "bonjour" into 
arrayName["greeting",tCurrentLanguage]

The odd VB syntax of returning a value from a function (procedure) by assigning 
the value to the name of the procedure is replaced in xTalk by the more 
standard return keyword.

PROCNAME = someValuereturn someValue

Similarities: xTalk, like VB, is not case-specific: somevariable is the same as 
someVariable, as are SOMEVARIABLE and sOmEvArIAblE. Unless explicitVars is set 
to true (enable variable checking in the menu) variables do not need to be 
declared before use. This is similar to VB's OPTION EXPLICIT. In xTalk 
single-word string literals should be, but in general do not have to be (unless 
explicitVars is true), quoted:

put red into tCurrentColor
put "black" into tCurrentColor
answer hello
answer "hello, sailor"

The following are not necessary in xTalk:
REDIM
LET
PI is already defined as a constant

The following VB constants map directly to the following xTalk keywords:

vbCRLF  return
vbKeyReturn return
vbNewLine   cr
vbKeyBack   8
vbOKOnly"OK"
vbNullStringempty
vbBlack "black"
vbWhite "white"
vbRed   "red"
vbBlue  "blue"
vbGreen "green"
vbYellow"yellow"
vbMagenta   "magenta"
vbCyan  "cyan"

more direct mapping:

' (comment indicator)   "--" or "#"
DIM X AS INTEGERlocal x or global x
PROCEDURE SomeProc  function SomeProc
DO  repeat
WHILE   repeat while
WENDend while
LOOPend while
SELECT CASE switch (use break statement between 
cases)
END SELECT  end switch
CASE ELSE   default
OPEN fileName as "x"open file fileName
CLOSE "x"   close file fileName
OPTION EXPLICIT explictVars
TRIM(SomeString)word 1 to -1 of SomeString

The following VB keywords have no mapping:
ON ERROR(use try/catch construct)

The following constructs have no direct equivalent:
WITH
END WITH
label:
GOTO label
dot notation:
instead of "lblMyLabel.Height" use "the height of field "MyLabel"
Timer controls
possibly use invisible buttons with "send 'Timer' to me in the interval 
of me milliseconds"
System and ActiveX controls in external libraries

Sheesh. You're worried about "several hundred thousand" write cycles?
I don't write to flash drives all that often - read cycles are much
more prevalent. I think more to the point is that I've outgrown my
smaller flash drives and had to move to newer and bigger ones.

There's a wonderful tradition that started many years ago when monks
began transcribing manuscripts. I believe they called it backups. I
don't have *anything* on a flash drive that I don't have backed up
somewhere safe. Usually multiple copies. But then that's just me being
paranoid that my media might self-destruct some day.

Re: baltic fonts not supported ?..

hi viktoras, how about this:

1) write the text outside (notepad or whatever)
2) paste into the text field
3) get the textFont of the field

then see if you can set the textFont to that field permanently and  
get better results?


i use macintosh so have no clever ideas. i also don't know any  
lithuanian. but when i used my text input on the macintosh to input  
in unicode lithuanian (just romanization of english words, alas), and  
converted it to HTML, it returned the font "Gnveva CE" (for Central  
European). Is there such a font on uour machine?

OT Adobe Serial/Ethical Question

2007-03-16 Thread Mark Swindell

Ethics and logistics question:

I just bought a used iMac with GoLive CS installed on it.  It didn't  
come with the install disks, but the program is authorized for the  
computer.  I'm wondering if I technically have the right to use it?


If the answer is yes, then do I have the right to move it to another  
HD/CPU and delete the original?


Of course, I don't know how to access the serial number on the iMac  
to authorize the copied program, but I'm curious if I should even  
wonder about it, or just dump it.


Ideally, I'd like to be able to move the program to my main computer,  
and reformat the iMac and give it to my mom... the original plan.  If  
I'm being a scurvy dog, I can just dump the CS version and continue  
to use my purchased copy of GoLive in Classic mode.  But I'm curious...


Thanks

Your script probably goes to each card to print it, so you are left on 
the last card that was sent to the printer. Just add a line after the

2. Why are pages that are printed not in collated order?  On both XP and

and page 4 in this order. This occurs in both the IDE and standalones. I 
know I don't give the user to choose collation as an option but you 
would think that the marked pages would be printed in the same order 
(1,2,3) which coincides with the marked order of the cards.


Are your cards in logical order, so that the third card the user sees is 
really card 3 in the stack? When Rev prints marked cards, it does them 
in the stack order. If the card that the user sees as the second card is 
really in the stack's fourth position, it will be printed fourth.

I just added a line to set the color of the group to a random color -- 
works just as well:


on mouseUp
  local tNum
  local twID
  local tFol
  local tDest

  put the colorNames into tColors  --< NEW

  put 500 into tNum
  put the windowID of this stack into twID
  put "/Users/rg/Desktop/untitled folder/" into tFol
  set the defaultfolder to tFol

  repeat with x = 1 to tNum
if the mouse is down then
  exit to top
end if
put x & ".png" into tDest
put x into fld "counter"
set the backgroundColor of grp 1 to  any line of tColors --< NEW
export snapshot from grp 1 to file tDest as PNG
  end repeat
  answer "Done!"
end mouseUp


Then I added a graphic in case there was something specific to that 
object type, changing the color of the graphic instead of the group. 
Same good result.

Unusual Problem

2007-03-16 Thread Charles Szasz

I am using Rev. 2.7.4 Studio for the Mac with OS 10.4.8.

I set up my printing routine to print three pages that are marked.  
Based on the user's responses, there is an optional fourth page or  
card that can be printed if additional scores are entered by the user  
with the other three pages at the same time. I used the Switch  
command to include the fourth page if there is or is not something to  
be printed. The routine works beautfiul  but here are my two questions:


1. When the printing is completed that has four pages or cards, the  
user is on the fourth screen that has the optional page that was  
printed. The print button is located on the third page where the user  
started the printing. This occurs on both XP and OS X standalones. I  
am using the print card command with Open Printing. Why is the user  
not returned to the third card where the print button is after  
printing is completed?


2. Why are pages that are printed not in collated order?  On both XP

These are small quirks but I am curious why this happens?

Signe,

I'd be interested in hearing more about this. I'm developing a  
similar approach with Rev, which I'm calling the Learning Web. You  
can take a look at it by downloading the beta version at


Mac OS X: http://asay.byu.edu/LW_MacOSX.dmg
Windows: http://asay.byu.edu/LW_setup.exe

A couple of people on the list have allowed me to link to stacks  
they've created as a demonstration of the concept. There are also  
links to a couple of stacks I've created and one that one of my  
students did.


We ought to explore the creation of a repository of web-based  
instructional stacks that could be run in this way.


Tell me what you think.

> [various comments about the wealth of resources available for Rev newbies]

I do appreciate there's a lot of good stuff out there. As a not-so-newbie I 
still find it bewildering where to look, and the landscape is constantly 
changing. It seems even a mere directory of these is a daunting challenge.

It's my opinion that we (you can consider that "we" the company, or the 
community, or both) need to develop a ore complete library of self-contained 
"starter" kits for various tasks that Revolution is well-suited for. A kit 
being: narrative; code snippets; sample stacks, etc.

That library should be at runrev.com, and actively maintained. They should 
all

- share the same look-and-feel in stacks
- use consistent style-sheets/templates for documentation
- meet standards of professionalism
- be dead-simple for the newcomer (no weird xTalk tricks or fancy-shmancy 
footwork)

I think a good example currently is the XML stack. Anyone who's tried to 
understand the revXML library is familiar with it. Many of the newsletter 
articles we've seen over the past few months are candidates. I'm curious 
about what some other kits might consist of. Email client? Media organizer?

What does the community think the topics should be? And is there anyone 
interested in writing them?

Good morning and thanks to both Ken Ray and you for your advice.  
When you say

I can't answer all your Windows question with authority, but let me  
just point out that if you have Rev 2.7 already, 2.8 is a free  
upgrade, as 2.9 will be.


The comments of others indicate that chances are very high that Rev

Implications of limited writes to flash drives

2007-03-16 Thread Richard Gaskin


Flash memory has an inherent limitation on the number of reliable write 
operations.  Unfortunately, that number is measured not in millions, but 
in thousands:


  Like all flash memory devices, flash drives can sustain only
  a limited number of write and erase cycles before failure.
  Mid-range flash drives under normal conditions will support
  several hundred thousand cycles, although write operations
  will gradually slow as the device ages. This should be a
  consideration when using a flash drive to run application
  software or an operating system.


The implications for applications are significant, esp. those which 
might seek the user convenience of an auto-save feature.


Have any of you had a flash drive fail on writes?
How serious do you think this limitation is in practical use?

Re: [OFF] Input/Info Requested

2007-03-16 Thread Joe Lewis Wilkins

Hi Marielle,

A few weeks back I broached that very issue. Or, maybe, even more  
ambitiously, about the total scope of available resources for RunRev.  
It had become pretty obvious to me that there are just tons and tons  
of materials, suggestions, approaches, et. out there, but the newbie  
to Rev has got to be bewildered. When I was working heavily with  
FutureBasic, I was pushing for the design of a few really good  
templates to be used by newbies of FB a starting point. We even did a  
few; and, except for its Mac only capabilities, FB is the best,  
fastest and easiest there is. Lots of it are in assembly language,  
and like this list, the FB lists are impressive, though not as  
"hurried".


Were it not for the fact that I am now simply swamped with  
architectural commitments, I thoroughly intended to pursue the  
template concept of Macinstruct.com;but it turns out that I'm  
actually having to take an hiatus from my column on Revolution there;  
perhaps for as long as a couple of months. Frankly, templates make  
less sense with Rev, because the interface design is so simple to  
begin with; meaning that an evaluation of the available resource when  
pursuing a specific type of design, plus a heads up with respect to  
the potential gotchas, is probably a better approach. Break down the  
kinds of things that might be attempted by someone, and they outline  
an approach that they might use to achieve those ends. I don't think  
there is a lot of new ground that would have to be broken, just  
guidance as to where to look for an specific challenge; since you can  
spend a lifetime reading all the stuff that is available, but not  
really find the things that a person might need at the time. I'm just  
running off at the mouth, so excuse me. I know you understand,  
probably far better than I do.


With FB, I tried to recruit a team to work with me on the "template"  
approach, and got a few takers, but ended up doing most of it myself.  
I assume it would be the same here, and I don't currently have the  
free time to take somethng like this on. Much as I would love the  
challenge.

Re: Duration of non supported applications

2007-03-16 Thread Bill Marriott
David,

> are
> many developers available.
> 2) Buy a commercial package
> 3) Adopt a mixed open source strategy

Unfortunately I cannot agree with you on *ANY* of these recommendations.

There's no guarantee (and I would argue, little potential) that these paths 
are going to ensure better long-term survivability than a Rev-based 
application that is running just fine on Windows Vista and Mac OS X today.

Regarding #1)

- So-called "standard web technology" is a moving target, faster-moving even 
than operating systems.
- It's a lot of development work and testing to get something approaching 
interactive multimedia on all major browser platforms today.
- When you do so, you're still relying on underlying multimedia libraries
- Revolution out-of-the-box provides superior capabilities for the end-user 
experience.

Regarding #2)

- There's very likely no such animal as an existing off-the-shelf product 
that does exactly what the existing solution does.
- Shoe-horning the solution into a product that might be "close enough" is 
simply trading one set of problems for another.
- Commercial products ain't free

Regarding #3)
- This is typical pie-in-the-sky "open source solves everything" wishful 
thinking and hand-waving
- Most of the issues that pertain to #2 and #3 apply here
- Anyone who's worked with open source knows it has its own bugs, issues and 
traps

Now, at BEST what you are saying is that you should spend significant 
time/effort/money NOW to solve a problem that may not occur for several 
years, if at all. Why? For all we know, the solution works fine as-is on 
current operating systems. If for some reason it doesn't (I suppose Vista is 
the most vulnerable) then, just grab Revolution 2.8 and re-save the 
standalone. Voila, you've just added 5 to 10 years of compatibility.

At WORST you are saying you should throw out perfectly good work for dubious 
returns with little guarantee that the end result will have the same 
functions and user experience... "just because."

Vista just came out "yesterday" and Intel-based Macs are not that much 
older. Do you really think a new generation of operating systems is going to 
be released imminently -- OSes that will somehow by default and unavoidably 
break hundreds of existing applications? And that large organizations are 
going to adopt that new paradigm, replace their hardware, and sacrifice 
their software infrastructure ... overnight?

Now a meta-comment:

If you really believe this, why the heck are you using Rev at all? These 
arguments could be used against any desktop application built with Rev, and 
undermine anyone trying to sell software based on the Rev platform.

For what it's worth, when I was testing Windows Vista I ran a standalone I 
created in July 2003 with Rev without recompiling. It worked just great. Of 
course I wasn't doing tricky stuff like registry edits but then again, how 
many standalones do that, and what is the chance an educational solution 
does so?

The truth is, Rev is the one development platform that "just works" across a 
vast array of operating systems and versions. You can run it on Windows 98. 
You can run it on Mac OS X 10.4.9. Yeah, I know there are glitches here and 
there, and you have to use 2.6.1 for Linux and Mac Classic (that will 
change). But understand that it DOES work and is remarkably robust. I'm not 
sure if MetaCard was available in 1997, but for all intents and purposes, 
those stacks still work fine a DECADE later, on both Windows 98 and Vista.

As for "resources" there are thousands of users of Rev, more each day, and 
I'm sure any of them would appreciate a referral for consulting should that 
dark day arrive when the apps finally, really do have to be updated or 
replaced. THAT is the time to worry about putting the train on different 
tracks... not today. (The Aztecs seem to think it's all over in 2012. 
Whatever comes first -- Rev apps breaking or the end of the world.)

I think for all practical purposes the answer to the original poster is: 
Find a Vista machine and try your stuff out. If for some reason it doesn't 
work, try re-building the standalone with Rev 2.8. It will undoubtedly work 
great and continue to do so for the forseeable future.

I'f I'm somehow misunderstanding you, please help clarify.

- Bill

Just a guess really, I have had this kind of problem when my external

Not really sure if it is a leak, just seems like the most likely.

Hi Mark,

actually neither of those will do anything... you forgot to put in a 
command between start and the '>' redirect command...


for example:
(diruse gets you the size of a folder for example)

get shell("diruse /m" && thisshare & "findstr /i sub-total")  -- retrieves 
the size of a share on a server which can take lots of time!

works but blocks ya waiting for an answer...

so what you should do is 

put "diruse /m,* \\buffet\mysharename > 
\\buffet\spacelogs$\diruse\bufduser20061127.log" into mycommand
get  "start cmd /c"  && quote & mycommand & quote
get shell(it) 

this will do what you want!

as simple and stupid as you think DOS can be, there's always more to learn

you're using v2.8 I removed the portion for earlier versions:



on mouseUp
  local tNum
  local twID
  local tFol
  local tDest

  put 500 into tNum
  put the windowID of this stack into twID
  put "/Users/rg/Desktop/untitled folder/" into tFol
  set the defaultfolder to tFol

  repeat with x = 1 to tNum
if the mouse is down then
  exit to top
end if
put x & ".png" into tDest
put x into fld "counter"
export snapshot from grp 1 to file tDest as PNG
  end repeat
  answer "Done!"
end mouseUp

Running this script twice in both MC and Rev completed without error, 
and afterwards the memory allocation for each was roughly the same as 
before.


What suggests this crash is specifically a memory leak?

Memory Leak on export png????

2007-03-16 Thread Dave

Hi All,

Please take a look at the handler copied below. This is an adaptation  
of Ian Wood's "export snapshot.rev" stack that can be downloaded from  
Rev Online.


I have changed in to use .png files instead of JPEG file, changed the  
counter rectangle graphic object to have an all green background (RGB  
= 0,255,0), I then select 500 iterations and press the "export from  
snapshot from object" button, this writes 288 files and then gives an  
execution error:


"export can't write to file, mask file or container  289.png"

 export snapshot from grp "counter" to file tDest as PNG

I also tried this without setting the background color and this does  
write all 500 files, but RunRev crashes  (unexpectedly quits) doing  
something unrelated a short while later. Also when this is running,  
the first 50 to 100 files go quite quickly but after that it starts  
to slow down.


Has anyone else seen this? I'm running on a Mac Pro, Mac OS 10.4.9  
RunRev 2.8.0.350.


I really need to get this to work correctly as I have do another demo  
next week and this is 90% of it!


Thanks a lot
All the Best
Dave

exit to top
  end if
  set the defaultfolder to tFol

  repeat with x = 1 to tNum
if the mouse is down then

Re: Linux questions for Jacque

2007-03-16 Thread Bob Warren

Jacque:

I'll try the experiment you suggest, but I think your last suggestion is 
probably the best one. I'll do it over the weekend if I can. And don't 
forget that I said I couldn't even TYPE accented characters correctly 
into a field. That applies not only on my own computer where Ubuntu is 
installed in English and I need a special key-sequence for the accented 
chars on my American International Keyboard, it also applies to my 
wife's machine where she has Ubuntu installed in Portuguese and she uses 
an ABNT keyboard.


Whatever is wrong with Rev/Linux 2.6.1 in this respect won't of course 
get fixed, but it would be a good idea to try and make sure as far as 
possible that none of this difficulty appears in the next release.


When I send Technical Support a copy of my test program, if you REALLY 
wanted to, i.e. you are dying of curiosity,  you could see what I am 
talking about yourself simply by copying Rev/Linux and my example 
project to the Desktop of a running Ubuntu Live CD. It's as simple as 
that: no installation of Linux or Rev is necessary. Just a thought...


[I'd just like to see someone do that with Windows!!!]

Jacque wrote:

Actually, this is probably correct. Fields can have a textfont property 
independent of the text chunks inside it. That allows you to have a 
field's textfont set to Courier and a text chunk in the same field set 
to something else. If you haven't specifically set the textfont of char 
1 to 290, then it will be empty and instead it will inherit the field's 
font.


What this tells me though is that it is most likely not a unicode issue. 
I was wondering if your problem might be related to the printing failure 
of Japanese fonts that popped up in another thread. Guess not.


One more thing to try: instead of pasting the accented characters from 
another app, try putting them in using numToChar(). Your fonts may 
differ from the ones I have on my Mac, but in Courier, for example, the 
two accented "e"s are numToChar(142) and numToChar(143). I could insert 
these into a field without pasting by saying:


  put numToChar(143) into char 1 of fld 1

I wonder if doing it this way would produce characters that Rev can 
print. Maybe there is something about pasting from another program that 
is making a difference.


If that doesn't work, then a short, 1-card stack with a sample field 
that fails to print would be a good thing to submit to the QC Center. It 
should print, RR has verified that, so if it doesn't it needs fixing.

Re: Duration of non supported applications

2007-03-16 Thread David Bovill

Signe - while I'd agree with the purely technical advice given, I'd have to
be frank and say that I would never advise the University to do this. It
would be a waisted effort in my opinion for you or the university to spend
any further resources on software that neither has an internal developer
available or proper external support. They have in my opinion three options:

1) Redevelop the software using standard web technology for which there are
many developers available.
2) Buy a commercial package
3) Adopt a mixed open source strategy

The first 2 will involve a significant up front cost, and most likely result
in limited (perhaps severely limited) functionality compared with a RunRev
approach, but will work out in the longer run. Either of these are the "safe
bet".

The last approach means a painstaking and somewhat risky attempt to share
development resources with other similar institutions and members of this
community (you mentioned Sivakatirswami). Unfortunately the present
community is not set up to develop open source projects where there is not a
strong vested interest (the Metacard IDE). This will I believe and hope will
change for the better in the near future. It has the advantage of costing
only time - but that is a cost. It also has no guarantee of success, but
putting more time into upgrading RunRev based software - without the
likelihood of gaining another dedicated developer is not going to work
either.

If you think you would like to explore the latter (3), my guess is you may
get a few people on this list interested enough to look at how we could host
and develop shared code for use in Educational environments (you can include
me) - if there is a will within the University and it matches a similar need
outside - then you have an open source project. That backed with a little
petty cash to pay developers (not me :) from this list and your in business.
If not I'd advise against using Rev and go for 1) or 2).

Hope that doesn't put a downer on things.

David - looks to me like this just doesn't work on OSX (works just fine
under Windows). You might be able to come up with some sort of horrible
hack
that involves one or other of the altBrowser callbacks (e.g.
XBrowser_click
elementID,browserID) and setting the htmlText of the browser directly but
it
won't be much fun to either implement or use.

Sorry I can't be more helpful.

Hello Signe Marie,




I agree with Ken. It would not hurt and would probably help to update

re-build the "portal" standalone with the latest rev engine. In my

No no, you don't have to install VISTA to use 2.8, have mercy :-D

Hi Martin

When you say invisible do you mean you can see the image by using  
'show image'?


"invisible" means "invisible", since that was in YOUR code:

...
create invisible image imgname in group "Pages" of stack  
"PrintPreview"

export snapshot from rect trect of window tWinID to pictvar as JPEG
put pictvar into image imgname of stack "PrintPreview"

...


There could be platform / rev version differences at play.


"invisible" is in fact crossversion and crossplatform ;-)

[OFF] Input/Info Requested

2007-03-16 Thread Bill Marriott
Hi everyone,

I'm helping to prepare some data sheets for RunRev on the topics of 
FileMaker, SuperCard, and Visual Basic. Basically, trying to understand how 
Revolution compares with those products in real-world usage. The result 
would be some narrative, concrete examples, and a comparison chart for each.

If you have knowledge using these other products I would very much 
appreciate talking with you about your experiences and in which situations 
you would use either Rev or the other product. Please contact me off-list 
at:

bill.marriott(at)runrev.com

Thanks in advance!

- Bill
