Uh, Mark, I don't think that's true. You can save data in other stack files
that are on disk, but if the substack is part of the standalone, I don't
think you can save the data because this would change the standalone and
that's a no-no.

Steve, I would recommend either saving your data to another stack that
exists as a file on disk, or save the data to a text file or database. This
way it becomes portable. Either way, you won't have to mess with the stack
structure, just the code that reads/writes data.

Unix engines

[Kevin Miller]

Hi Everyone,

There have been some questions about when we update the Unix engines.  Most
of our Unix users tend to upgrade more slowly, running server systems or
other mission-critical installations.  Its quite common for there to be a
multi-year gap for these users in deciding to upgrade.  The OS upgrades on
these systems are also slower and Revolution tends to become out of date
less quickly.  A handful of you do need to upgrade more frequently, but the
numbers that do this are truly small.  As such we do have to prioritize
carefully the amount of time we spend on this activity.

We will next update the Unix engines in July this year.  In the mean time,
the existing Unix engines are available from support, and you should
continue to use those.

Should you have any questions or concerns regarding this policy, please
contact [EMAIL PROTECTED] directly.

Kind regards,

Kevin

How do I turn off autostart?

[Len Morgan]

It seems that when ever I load a stack into the IDE to work on it, it 
runs the preOpenStack handler but I would like to turn off that feature 
while I'm developing (so I don't accidently code an infinite loop in the 
handler).  It would be ok if going from edit to run had this behavior.  
Is there possibly something like MS Access has where if you hold down 
the shift key while opening a database it won't run the autoexec macro?

Thanks!

Stack saving clarification

[Len Morgan]

I read somewhere here in the last couple of weeks that if you use a card 
in a stack for preferences or something like that, you can't have that 
stack INSIDE of a standalone?  Is that true?  If that is so, why would I 
want to use cards/stacks to hold information that is subject to change?  
What suggestion would you have if I would like the user to be able to 
point to a database or particular server (which I don't know when I 
build the standalone), or change their background colors or something 
similar?

Would the best approach (and I realize that "best" is a loaded word) be 
to have an external text file that gets "imported" into the card that 
has the preferences and then saved back to if their are any changes or 
have a stack that is external to the exe?  Or something else?  It seems 
to me that if we can save changes in the stand-alone, we should change 
it to "stand in a small group"  :-)

Re: Can a Revolution standalone application save data?

[T. R. Ponn]

Steve,
I would save it to a text or binary file upon quitting.  Then either 
automatically open it during startup (ie cfg file)...or provide the user 
with a "open file" scheme in your app.  You can tamper-proof (to a good 
degree) by building an encode/decode function with a checksum.  All 
fairly easy to accomplish.

You can also generate many checksums...each one for a different section 
of your file...this will drive hackers nuts. :-)

As for adding references to works by others developers, it sounds good

important ones: there are great contributions in this list, in MC list, 
stacks and tips on RevOnLine, Revnet, on the web sites of most of the 
great contributors to this list and so on.
May be someone knowing most sources available better than me would be 
kind enough to post such a "sources" guide (could be a stack with 
arranged links).
It should be very appreciated by beginners and all of us :-)

By the way, i noticed that you mentioned that animated gif could not

   I don't think there's anything like that built into Rev, but you can do it 
yourself:

on preOpenStack
  if the environment = "development" then exit preOpenStack
  ...

Actually, there is. If you click on the toolbar button that says "Messages",
it will get a lock icon on it. This means messages are locked and won't be
sent normally. Then simply open your stack. Your stack won't get the
preOpenStack message sent so it won't trigger. Then, when you want messages
back on, click the toolbar button again and the lock disappears.

Creating MySQL Databases

[Peter Reid]

I'm just starting a project using MySQL for the first time.  Having 
looked at the Rev 2.5.1 documentation, I'm happy enough that I can 
access and update MySQL databases as required.  However, what I can't 
see is how I can create and carry out basic administration of NEW 
databases.

My project involves my users being able to create a new database to 
support work for a particular client.  Each new database will be 
based on a template database which consists of 23 tables - 17 
pre-loaded with standard data and 6 empty tables that will hold 
client-specific information during use.  The MySQL server will be 
running on a networked Mac OS X system (possibly Server X 10.3, but 
also possible just standard OS X 10.3), accessible to all users 
within the organisation.

Using phpMyAdmin, YourSQL and MySQL 4.0.24 (under Mac OS X 10.3.8), 
I've been able to create a template database with all the tables and 
standard data in place.

However I can't see how I can code in Rev to carry out basic database 
administration:
- create new database (as a copy of a template database)
- rename a database
- delete a database
- dump a database
- reload a database from a dump

Obviously, I could send a series of shell commands, using MySQL in 
batch mode.  However, why I can't I do the above using the Rev 
database library?  Also, if I have to use the shell function, how can 
I do this to the MySQL server running on a different system over the 
local network? (i.e. the program is running on one system whilst 
creating and managing a database on a different system across the 
local network).

Note that whilst I can use phpMyAdmin to do all the database admin, 
my users CAN'T!  They need simple "Create DB", "Rename DB" type 
actions, which is why I'm trying to include these in my Rev project!

Any advice, help please?
Peter

Part border on image

[Beat Cornaz]

I use images (in a  rectangle form) as sliders to get a minimum and 
maximum value. I want to get a border at the bottom of the image (or 
at the top). I use images because of the blend property. The 3D 
border won't do, as it is bottom and right side.

Of course I can introduce a separate line object to do the job, but I 
need to keep it as simple as possible, because it is getting already 
complex enough, without making groups with images and lines.

Also : I don't understand the first to eight color. Doesn't that work 
with images? In the inspector of an image I can select colors for 
first color etc. but nothing changes . If I go back to the inspector 
of that image, the color I've chosen are gone as well.

I can't manage do give a radio- or check button a color. The name, 
ok, but the button itself doesn't react to any color adjustment I 
make.

Thanks, Beat

I got it. IOW, opening a socket doesn't work unilaterally. The

Right. When you open a TCP socket  (i.e. open socket to "host:port"), 
a TCP connection is formed. A packet is sent from your machine's TCP 
stack to his, and he sends a reply (assuming some application has done 
"accept connection" on the correct port). If there is no-one listening 
on that port, the remote machine will either ignore the incoming 
packet, or send back a "reject" packet.

When (if) your host receives a positive acknowledgment, then the 
connection is successful (from your point of view); your TCP stack 
then sends him back a third packet - and only when he receives it does 
he consider the connection complete.  (He can't consider it complete 
until then, because there could be a problem getting his packets to 
you - the only way he knows that has succeeded is when you reply).  
You may hear this referred to as "TCP's three-way handshake".

Note that when you open a UDP socket (i.e. open datagram socket to 
"host:port"), things are completely different. UDP (datagram) is 
"connectionless", so the open socket does not cause any network 
activity, and will generally succeed provided the "host:port" have 
valid values.

I'm going to figure out this server stuff one of these days.
And once you do, you'll realize how simple it all was to begin with, 
and wonder why no-one ever wrote a decent explanation of it in the 
first place. It's because most of us can't write decent explanations 
of anything :-)

Buttons, Fields & Columns

[Michael Mandaville]

Sarah,

This was extremely helpful.  I followed your instructions and it worked just
great.   BTW, you were the one who was so kind to give me your opinion on
Revolution which convinced me to move forward!I had to figure out that
you used Radio Buttons and then put them into a group, but then got it to
work.  I also tried it with CheckBoxes and got that to work.   I was also
able to figure it out with OptionBoxes and Pulldown Menus.  I'm saving the
stacks as I work on them for my examples.  I'm trying to go through all the
controls as I do this.

1.  COLUMNS:   I have three elements - Primary, Secondary and Task.   I
already got it to sort on the Primary.  I can then set up a button for the
Secondary aswell. How do I send them items to a nice even scrolling field of
three columns?  In that way, I suppose, I can sort on each column or set up
a sort order. 


2.  INTERNAL BUTTON:  Once a person makes a choice in the Primary field
(which is to establish Priorities using "A","B" and "C")  and it is sent to
a list, I've seen where these Lists have the choice listed, but also access
to an option Menu within the List.So that if a priority changes, they
can go into this List, hilite the Primary choice and change the ABC to
whatever they want.  In effect, it's an Option Menu within the List.

Thanks for everything, Sarah,

Michael

And the new version - available during the next days - can be placed

Another change is a simplified search input and the extra option to 
search all of the XML files of the "Dictionary", "Faq", and "Topics" in

Re: Creating MySQL Databases

Peter,
I recommend that you check your SQL database documentation for there

http://dev.mysql.com/doc/mysql/en/backup.html  -- this will cover your

Sorry but I did not find anything on renaming databases... but you can 
dump them, change the SQL with a simple replace "oldname" with 
"newname" in the SQLConteainer then, execute that SQL, then delete the 
old database, it will solve your problem

Also if you're fiddling with SQL and Rev, check Trevor's libDatabase, 
it's an amazing lib.

can dump them, change the SQL with a simple replace "oldname" with 
"newname" in the SQLConteainer then, execute that SQL, then delete 
the old database, it will solve your problem

Also if you're fiddling with SQL and Rev, check Trevor's 
libDatabase, it's an amazing lib.

Cheers

Thanks for the response and the links.
I realise that I can do all I want directly through a command 
interface and that phpMyAdmin simply takes advantage of the features 
built into MySQL.  What I can't see is how I can encapsulate this 
into a Rev program, particularly one that will be running on a system 
that is NOT the host for the MySQL server but on the same local 
network.

If my Rev program were running on the system acting as the MySQL 
server host, then I could use the shell() function controlling the 
MySQL server in command line mode.  However, my program will not be 
on the same system, so I don't see how I can build this into the 
program?

It seems that the Rev support for SQL databases assumes that 
databases are pre-existing and managed externally. Rev seems to 
provide all the commands you need to read from and update SQL 
databases, but not the commands to create and manage them.

On the "renaming" front, I had assumed that phpMyAdmin did a dump & 
reload with new name to accomplish this.  as you say, database 
renaming doesn't seem to be a native feature of MySQL (and several 
other SQL databases I believe).

You mention Trevor's libDatabase - where can I get hold of this, it 
could be very helpful?

Characters in names

[Graham Samuel]

I can't find a list in the RR docs of legal characters for variable  
names. Obviously letters of the alphabet (at least the ascii version)  
and the numerals are OK, plus hyphen and underscore - but what else?  
Clearly no character used as an operator, like \ or +, can be legal,  
but maybe some others are: for example is period (full stop to me)  
permitted? If I've missed a complete list, can someone please point me  
at it?

TIA

Don't think there is one - that would be too close to a reference 
definition of part of the language.

You can't have hyphen, that would be a minus operator.
You can have full stops - but there was a recommendation to avoid them 
if possible, in case of future expansion into "object" notation.

So basically letters, digits and underscore (and period, but avoid if 
possible)

Re: Location of the insertion point in a field

[Pat Trendler]

Mikey,
From the docs (search Topics)
How do I find out where the insertion point is?
You use the selectedChunk function to find out the location of the insertion 
point.

When there is an insertion point but no text is selected, the selectedChunk 
function returns an expression of the form char nextChar to prevChar of 
field fieldNumber. For example, if the insertion point is in field 3, 
between character 10 and character 11, the selectedChunk function returns 
char 11 to 10 of field 3.

FWIW, I can tell you I've used "?" as a prefix character without problems,
but it has been said that the MC/Rev engineers might use this character in
the future for the engine.  Also, I would recommend NOT using a standard
hyphen "-" unless you explicitly quote your names since the engine assumes
this to be negative or subtract and will try to evaluate the name as an
expression.

In my own work, I prefix almost everything with an underscore: object names,
custom properties, etc.  This allows me to quickly identify my objects/names
and also use the equivalent of reserved words (ie _hilite, _top, _max, etc)
without having to worry about reserved name conflicts.  Some folks have
argued that you can't use a double click to select the entire word/name in a
script when using this convention, but this is irrelevant since the
underscore is used as a non-changing character.

I doin't know about variable names, but you can have these chars in
*handler* names:

  ? (question mark)
  ` (backquote)
  _ (underscore)
  @ (at-sign)
  # (pound sign)
  $ (dollar sign)
  '  (single quote)

So you can do this:

 on DoIt?
  answer "Hello"
 end DoIt?

or

 on Cash$Check
  -- cash check
 end Cash$Check

However as many have said, RunRev may use these special chars in the future
so I generally avoid everything but the underscore.

Re: Can a Revolution standalone application save data?

[Sarah Reichelt]

You can save information in a standalone to a substack of the
standalone, just not to the mainstack.  For example, you could make
make your opening splash screen  your main stack, and have any number
of substacks affiliated with that main stack.  This is how you save
information without writing it to the mainstack, which can't be done,
you're right.
Uh, Mark, I don't think that's true. You can save data in other stack 
files
that are on disk, but if the substack is part of the standalone, I 
don't
think you can save the data because this would change the standalone 
and
that's a no-no.

If you check the box in the Standalone settings that says "Move 
substacks into individual stack files", then you can do it this way. 
This method allows you to work with a single stack file in the IDE, but 
have it writable when you build an app.

Sarah

Re: Creating MySQL Databases

[Sarah Reichelt]

I'm just starting a project using MySQL for the first time.  Having 
looked at the Rev 2.5.1 documentation, I'm happy enough that I can 
access and update MySQL databases as required.  However, what I can't 
see is how I can create and carry out basic administration of NEW 
databases.

Hi Peter,
Here is my script for creating a new database. It connects directly to 
the "myslq" database as root (or any user that has the right 
privileges) and sends the create database command to that. I have only 
done it on a local database, so you will need to change the value for 
dbAddr.

I don't know how to rename a database, but if you can find the SQL 
command to do it, then I would hope that this technique would work for 
that as well.

Cheers,
Sarah
on mouseUp
  put "root" into dbUser
  put "mysql" into dbName
  put "localhost" into dbAddr
  ask password clear "Enter root password:"
  if the result = "Cancel" then exit to top
  put it into dbPass
  put revOpenDatabase("MySQL",dbAddr,dbName,dbUser,dbPass) into dbresult
  if dbResult is not a number then
answer error dbResult as sheet
exit to top
  end if
  put dbResult into dbID
   ask "Enter the name of the new database:"
  if the result = "Cancel" then exit to top
  put it into newDB
  put "CREATE DATABASE " & newDB into dbSQL
  revExecuteSQL dbID, dbSQL
  put the result into sqlResult
  if sqlResult is a number then
answer information "Database " & newDB & " created." as sheet
  else
answer error sqlResult as sheet

Re: Search Rev docs "at the speed of thought" Bad Language alert!

[Pat Trendler]

Just looked at your new screenshot - absolutely bleeding fabulous!
All manual style ebooks should have a search function like this.
It just gets better and better.
Could we be able to select and copy please?
Pat
And the new version - available during the next days - can be placed 
either into the main Revolution or Metacard folder (where the engine is) 
or into the "plugins" folder of Rev or the MC IDE; "SearchDocs XML 2" 
will detect where it has been placed and set the directory paths for the 
search accordingly.-

Another change is a simplified search input and the extra option to 
search all of the XML files of the "Dictionary", "Faq", and "Topics" in 
one run. Searching these combined 1992 files will slightly increase the 
average search time to about 160 milliseconds  (WindowsXP, 2 GHz), which 
should be still very much tolerable.

There is a new screenshot at

This is from "About containers, variables, and sources of value":
Variable names
The names of variables must consist of a single word and may contain 
any combination of letters, digits, and underscores (_). The first 
character must be either a letter or an underscore.

Here are some examples of legal variable names:
  someVariable
  picture3
  my_new_file
  _output
Here are some names that cannot be used as variable names:
  3rdRock -- starts with a digit
  this&That   -- "&" cannot be used
  My Variable -- more than one word
Avoid giving a variable the same name as a custom property. If you 
refer to a custom property, and there is a variable by the same name, 
Revolution uses the contents of the variable as the name of the 
custom property. Generally this will produce unexpected results.

  Note:  Global variables whose names begin with "gRev" are reserved 
by the Revolution development environment.


(As Alex notes, there are characters other than letters, numbers, and 
underscores that will work in variable  names, but this isn't 
guaranteed to go on working, so those characters are best avoided.)

Can Revolution create a large, colored cursor?

[Stgoldberg]

As a beginner I'm really finding this forum extremely helpful. Perhaps 
someone can help with this question:   Although the instructions say that a 
cursor 
has to be in black and white and not larger than 16x16, I'm wondering if there 
is a way around this.   Many games, for instance, have large cursors, e.g. a 
large grasping hand when the cursor moves over an object than can be grasped.   
I first thought that perhaps one could use a hidden image of a grasping hand 
that was made to appear over the location of the cursor when the cursor passed 
over the object to be grasped, in a script like this:

on mouseEnter
set cursor to none
set lockcursor to true
set the loc of image "LargeHand" to the mouseloc
end mouseEnter

on mouseLeave
set lockcursor to false
set cursor to arrow
hide image "LargeHand"
end mouseLeave

It would seem that this should work, but it doesn't, since the   "LargeHand" 
image for some reason keeps flickering whenever the mouse moves over it.   
Does anyone have any suggestion   as to how to get this method to work, or 
another method to allow for a larger, more elaborate colored cursor?   Thanks.

- colored cursors didn't seem supported
- colors didn't dispay correctly
- transparency masks not supported on non-bitmap images.

No one ever helped so Im stuck as you are...
I think there's a bugzilla for this too...

cheers
Xavier

RE: revDatabase

[Harvey Toyama]

Hi, 
MySQL 4.1 was my first encounter with the database. The original
complaint is due to 16 vs 41 byte passwords. 

Since Revolution is the only client application I have, and since it
only support old passwords, my solution was to add "old-passwords" in
the [mysqld] section of the my.cnf file. You can update the grant tables
to use old passwords with:

SET PASSWORD FOR 'some_user'@'some_host' = OLD_PASSWORD('newpwd');

It worked for me.

Re: Problem with 'filter' on large lists

[Terry Judd]

Actually the problem seems much wider than that. I'm seeing 'dodgy' 
returned data for some (but not all) smaller chunks of my data as well 
(<25000 lines). Good thing that repeat for each constructs are so fast. 
I'll stick with a custom filter routine based around that for the 
moment and see if I can tie down the problem (with the filter command - 
or my data) further.

Cheers,
Terry...
The filter command seems to be 'dodgy' when working with large lists 
(>10) lines - ie gives different results to when the same data is 
broken up into a number of chunks. Has anyone else seen this or is it 
just me?

All I'm doing is some simple filtering of long lists of urls as in - 
filter theURLs with "*unimelb.edu.au"

Cheers,
Terry...

As it turns out, Mikey, you picked one of the few keys that would actually
do something about changing the focus, etc. when the key is struck. Look at
"tabKey" as the equivalent of "keyUp", meaning that it takes place *after*
the key has been struck, so it actually tabs out of the field (or at least
clears the selectedChunk) before you trap it. What you want to use is
"rawKeyDown" instead:

on rawKeyDown pKey
  if pKey is 65289 then  -- key code for Tab
get the selectedChunk
answer it
  end if
  pass rawKeyDown
end rawKeyDown
