Question about the revVideoGrabIdle loop

[Doug Lerner]

If you have the following in a handler:

  repeat while recordvideo is true
revVideoGrabIdle
wait for 1 millisecond with messages
  end repeat

then the handler never finishes, right? I have this in my openStack handler.
It seems to work ok, but is it ok to never actually finish the openStack
handler?

avoiding weird effects when moving the video grabber window

[Doug Lerner]

When the video grabber window first appears it is in the upper left corner
and then jumps into my step because I have set its rectangle in the
openStack handler.

Similarly, when I move the stack "containing" the video grabber, first the
stack moves and then the video grabber comes after it.

Any way of avoiding these two odd effects?

Thanks,

doug

This may be where you go off base. All the "deleteSomething" messages 
are sent immediately *before* the object is deleted. It notifies you 
that a deletion is about to occur.

The lock messages locks all the messages *associated with* the deletion of
the graphic, even if there are dozens of rev messages sent out after the
graphic is deleted?
That is what I wanted to clarify.
Locking messages stops all of them until messages are unlocked again, or 
until the handler ends. Messages always resume on idle.

The rev-related messages aren't sent during your handlers anyway (well, 
not most of the time, there could be rare exceptions.) When you lock 
messages in a handler, the lock is only effective within that one handler.

If your handler calls other handlers, then the lock on messages will 
remain effective until the original calling handler ends, or until 
either of the handlers unlocks it.

iconic crash boom bam

[Thomas McGrath III]

I created a new stack with decorations set to empty and the rect of the 
window set to the screen size. I put a button on my no decorations 
stack to iconic it.
It seems (no docs to support it) that the iconic will not work with out 
the decorations set. BUT when I temporarily set the decorations and 
try, IT CRASHES badda bing.

--in button
on mouseUp
lock screen
set the decorations of this stack to "Title,minimize"
set the iconic of this stack to true
unlock screen
end mouseUp
--in stack
on unIconifyStack
set the decorations of this stack to empty
end unIconifyStack
That's it... This crashes revolution every time I try it.

What is causing the crash?

Tom
Below is part of the crash report because the whole report is too big

iconic

[Thomas McGrath III]

I am having a real problem with the iconic property.

The docs say that you can set the iconic of a stack to true to minimize 
it BUT with my stack which has the decorations off it not only does not 
do anything but it also stops all of my buttons from executing. The 
buttons highlight normally but clicking them does not do anything.
I set the iconic to false but nothing is changed.

The docs do not mention anything about the decorations for use with 
iconic.

Does anyone have any ideas on the true behavior of iconic?

Thanks

List field behavior

[Robert Presender]

I must be doing something wrong.  Help will be appreciated.

Using OS 10.2.8 and 2.1RC1
I have a list field with three lines in a test stack.  When line 2 is 
deleted (via msg box),
line 2 is deleted but line 3 does not move into line 2's place. The 
number of lines still shows 3.  In SuperCard,  Line 3 moves to line 2's 
position and the number of lines is 2.
If I add a line(via the msg box), the added line goes into the deleted 
line 2 position.

Is this normal behavior?  TIA

iconic

[Thomas McGrath III]

Can anyone explain to me why set the iconic of this stack to true does 
not send it to the dock like the docs say it will? I have all 
decorations off for the stack. I need them off for space reasons. But I 
still want to minimize my window.

The docs don't mention a relationship for iconic with decorations

Re: web cam capture

Doug,

Apple said the iSight would not work with iPhoto or iMovie and was not 
meant to do such. Also iChat will not let you access the built-in 
controls found in iSight. REV let me control everything. I mean 
everything. The focus on the iSight is way cool. Other features are 
great as well.

But pay close attention to opening the videograb session and 'closing' 
the session. I forgot and caused a bit of weird stuff.

I tried it on my own first and then went and checked out the sample 
stack provided and it all came into place.

Hello all , i am struggling to understand the scipts in this program . the prorame was 
downloaded from
http://www.runrev.com/revolution/developers/developerdownloads/usercontributions.html
 the things I dont understand are :
It wont calculate my age from thease two inputs : date of birth  8/2/1961 , assesment 
date 30/1/2004

and how do parameters work , where does param(1) and param(2) come from 

if centurycutoff  is set to 35 why does it work for dates from 1970 onwards only 

I am using version RR 1.1.1. (it was a freebie on a magazine) full version aparently 

oh and one more question please why have a correction and add it to item 3 of enddate?

many thanks from a novice

Yes.  For example, opening the internal modem on OX X locks for 3 
seconds.  I believe this even occurs on a non-blocking open for some 
reason.  I might be doing something wrong.  If so, I seem to be in good 
company.

However, I think it reasonable to keep Revolution to an event model.  
(Though I might be convinced otherwise.)

Threads might be pushed beyond these two barriers:

Enhanced 'open process' to command-line Revolution might be a way to do 
this.  This is begging the question in Barry's case, because that is 
where the weakness lies.  But, with this, many doors will be opened.  
(By "enhanced" I mean empty buffer vs closed pipe issues are resolved 
and 'open process' separates input and output pipes for Transcript 
handling.)

The other place is in threads created by and managed by externals (and 
typically written in C).  I have put that off in my projects, and want 
to resolve some things first, but this might end up being a way to go.

There are already at least two lightweight threading system present in Rev:
the "send in..." and "wait xx with messages" commands.

These commands allow you have multiple scripts running simultaneously, all
under their own control.  On one project I ran around 40 simultaneous
animation scripts on Mac systems without issue (the Windows version was bit
problematic) but lots of folks on the list are doing this type of thing.

Of course, you'll get some slowdown if you do heavy media actions like
moving image objects, changing blendLevels, loading and unloading media into
players.  But overall, using "send in" and "wait with messages" constructs
allow the equivalent of threaded events.

now, and it's the easiest preferences I've ever done (it would be an 
absolute nightmare doing the same thing using the Mac Toolbox Dialog 
Manager).  Bottomline, I can't remember the last time I was this

So, in amongst all the questions and problems that arise on this list, 
I thought the RunRev team might want to know what a great product

displaying messages returned from "shell"

[Barry Levine]

I'm using the "shell" function to call some routines; creating a disk 
image is a good example. There is some verbose data returned which, if 
you use "answer shell(etc., etc.)" provides a dialog with -all- of the 
responses from the shell at one time.

Is there a way to provide this feedback to the user as the individual 
responses occur? It's not a critical item but it would smooth out the 
user interface a bit. I'm thinking of, perhaps, a progress bar with 
some text so the user knows what's going on.

Thanks,
Barry

Good Evening Ray,

Have fun and, please, believe me : even if the MC/Rev engine is mostly
undocumentend in about its ability to be used to develop
profesional-grade n-tier applications or server-side applications
servers, it's really one of the two or three best tools availables,
today (and since years - MC 2.32 and up), to share datas over TCP/IP.

Since i use it in such kind of networked workflow apps, i never had to
go back to others platforms such as Weblogic, WebSphere or WebObjects.

The best from the java world (Eclipse, JBoss, Tomcat, the J2EE EJB's
design patterns, Andromda or Hibernate,...) are great tools too but, the
java engines, by them self, ar'nt...

If you are searching about what ACID RDBMS to bind to your MC/Rev apps,
try PostgreSQL (best suited under *NIXes, including MacOSX, than under
Windows. It rooks in all the tasks we can have to manage.

Last but no last, the MC/Rev engine is NOT SUITABLE in about critical
cgi tasks. Choose PHP, Perl or Python instead, even to bind all kind of
MC/Rev applications servers to Apache trough a simple sockets
listener/ports translator.

Hope this helps,

I think one of the weaknesses of the 'accept' method for checking for 
multiple apps is the potential of collisions here.  The other problem 
is that this will not work if tcp/ip networking is not set up for some 
reason.  You might also want to make sure this does not force a dialup.

Another alternative is to use an external that makes appropriate 
Windows API calls that are designed for checking for multiple instances 
or otherwise handling them.  If you are not up to attacking the 
creation of an external, you can have one made.

Off the top of my head:

function unlockApp

The system should close the listening port when the app quits, but you 
might want to put the unlockApp in all the right places, anyway.

The specific message on OS X when the port is busy is "can't bind 
endpoint", but I have noticed that messages do not always line up 
between systems.  You can also check the syserr() to get the OS error 
code if you want to make sure the exact reason of failure is because 
there is another app using the port and not because the networking is 
broken or something.

Try 'accept' on some obscure port.  If it fails, assume that another 
app is running.  (Immediately close any connections in the call back, 
should any be made.)  I'd try UDP first.  If you need to listen to a 
port anyway, you are set.

You could try creating and deleting a folder.  This will work faster 
than a file, I think.  If you need some temp files, anyway, put this 
where you put your temp files and put your temp files in there.  You 
may need to work out the rare case of two programs trying to run at the 
same time.

There is probably some shell command you can use.  That may work well, 
since you only need one platform.  This also needs to address the 
problems of two starting at the same time.

If you feel comfortable with two not starting at the same time, then 
you don't have to worry about that.

The openProcesses() function applies to processes opened with 'open 
process'.

Re: web cam capture

[Thomas McGrath III]

doug,

The video capabilities were camera independent so "IF" the camera can 
be accessed by 'other' programs it probably can be accessed by REV. In 
the case of iSight which apple says is not meant to be accessed by 
other apps, REV can see it just fine AND control all kinds of features 
in it that can't even be controlled by apples own apps.

So if the driver for the camera is 'standard' enough to work in say 
"oculus" or some other web app then REV can definitely handle it.

I had great results after playing around with it a little bit.

re launching a windows stack

[Thomas McGrath III]

Hello all,

Same stack as before. Users are complaining that the CD is set to auto 
launch but if they want to re-open it once the CD has already been 
inserted and they have quit the program they can't find the stack file.

Problem is in order to launch in windows the stack file is in a folder 
on the cd since it can not be at the root level to auto launch. But if 
it is launched from in the folder it looses its links.
The autoinf file makes the stack think it is at the root level (which 
it is not) BUT if launched from the folder it is in then the paths to 
the media folder are broken.

Will a short cut make the stack think it is at the root level just like 
the autoinf file does?
If not how can it relaunch with out having to reinsert the CD again and 
again

Thanks

Minimize

[Thomas McGrath III]

Hello,

Does anyone know if I can put a Minimize button in my "special" window 
stack. The stack has decorations set to empty and has no window border 
at all. I do not want to use the standard window decorations.

The problem is that windows people are telling me that the stack does 
not show up in the task bar. "alt" & "tab" do not work on windows with 
this stack. "command" & "tab" work fine on the mac and the stack shows 
up in the dock.

reason: I could not find an exceptable cross-platform window size 
solution on 800x600 screens that handled my image sizes. I could not 
change the image sizes so I needed the window to be exact. But if the 
window size was the right size on macintosh it would be off on windows 
and vice versa. There would be either a cut off section or the window 
would not cover the screen completely. This window size was discussed 
heavily on this list before and I did not see a good enough solution.

So I would like to hide/minimize the window on mac and windows.

Hi Doug,

The 'revXXX' messages only get fired when the 'XXX'
message gets sent -- it's a long story, but you can
find out how it works in the Rev IDE frontScript and
backScript.
So if you 'lock messages', the engine eats the
'deleteGraphic' message, and it isn't going to send it
to any other object either, which means the 'revXXX'
messages aren't triggered.

Hope this clarified it,

Jan Schenkel.

Hi Sjoerd,

I had the same problem a while back when I was
experimenting with the cgi-engine ; the quick solution
is to copy the database drivers into the same dir as
the engine and the cgi-scripts.

You'll find these in your Revolution folder in the
directory /components/database_drivers/

The cleaner way is to use the command
'revSetDatabaseDriverPath' to point to the correct
directory on your server before making any calls to
the revdb functions.

Hope this helped,

Jan Schenkel.

Re: Suppressing a message?

Thanks for your reply.

But... how do you know which are the messages that are blocked?

For example, the following seems logical too:

1. lock messages (all messages are blocked)

2. delete graphic "a"
- graphic gets deleted

3. unlock messages
- messages continue again

4. the "unlock messages" took place essentially instantly after the graphic
was deleted, but before the deleteGraphic message was sent (since it is a
separate message that is sent when the graphic is actually removed from the
stack).

That is guaranteed not to happen ever?

The lock messages locks all the messages *associated with* the deletion of
the graphic, even if there are dozens of rev messages sent out after the
graphic is deleted?

That is what I wanted to clarify.

When you do a 'lock messages' the engine will eat
_all_ the messages it would have sent, including the
'deleteGraphic' message.

Let's explain this with the following script :
--
on mouseUp
  lock messages
  go card 3 of stack "Foo"
  delete graphic "Bar"
  go back
  unlock messages
end mouseUp
--

As soon as you lock the messages, the engine will no
longer send *any* messages, until you unlock or the
engine reaches the end of the handler.
So when you
  go card 3 of stack "Foo"
the engine won't send 'closeCard' or 'openCard' or
anything like that.
And when you
  delete graphic "Bar"
the graphic will be deleted, but you won't get a
'deleteGraphic' message.
And when you finally
  go back
again the engine won't send 'closeCard' or 'openCard'
or anything of the sort.

In short : it just blocks *all* messages.

Hope this clarified things a bit,

Jan Schenkel.

At the moment I'm desperatly trying to get a database connection to work
from within a CGI script. I keep getting the 'revdberr: invaldid database
type' as connection ID.

The database type supplied is correct (tried both 'MySQL' and 'mysql'). I
also tried if Revolution has the permissions to acces the specified
database-drivers directory, and I can read from the *.so files.

What can be the problem here? Is there any way to check for the supported
database types?

Thanks in advance for any help,
Sjoerd Op 't Land

Ann: Stealth Browser pre-announcement

[xbury . cs]

Im looking for a couple testers/helping hands to pretest the release of
this most excellent X Stealth Browser v1.0... 

Please reply directly... I'll be here until 16h00 GMT-2 (Brussels time)... 
After that,
I just might post it on monsieurx.com... 

It's as plain vanilla browser as it gets, does images or not (for 
stealth). 
Reworks the HTML to make sure it's displayed as decently as RR 
permits. It is not perfect (table tags are just deleted for example) but 
it's definitely better than the original!).

I'll probably integrate some webstyle obfuscation (so links are not so 
blatantly
recognizable...) and other google tricks later if there is interest or 
need...

Comments and beer mugs welcome as usual...

But... does the above example block all messages associated with "delete
graphic"? Why would it?

Does switching the lockText of the field back and
forth help -- I know that forces a redraw.

tips on refreshing images in fields?

[rodney tamblyn]

If you've set an image in a field (using imagesource) are there any 
tips on ways to make the images refresh and display properly when the 
field is scrolled up and down (I tend to find after scrolling that the 
images do not display correctly until the screen is redrawn by force, 
eg change tool, lock screen etc)

Re: revInitializeVideoGrabber question

Hi doug,

The doc is wrong, a parameter is missing.

The correct syntax is :

revInitializeVideoGrabber the short name of this 
stack,"QT","100,100,200,200"

Regards.

Thierry.

Hi Doug,

When you 'lock messages', the engine will not send
messages, but it doesn't save them for later use,
either. So there's no need to worry that it will be
sent after you 'unlock messages'

Hope this helped,

Jan Schenkel.

Hi Doug,

The best way to learn how the video grabbing commands
and functions work, is by examining the scripts of the
sample stack 'Video_Input.rev' which you'll find in
the 'Sample Stacks' folder inside your Revolution
folder.

Hope this helped,

Jan Schenkel.

Hi Yves,

I did a quick test but it seemed to work for me --
have you checked the content of 'the result' after the
clone command ?

Re: Suppressing a message?

[Brian Yennie]

Yes, this should block it. Try it out.

A typical use of lock messages is to navigate to a card/stack without 
triggering openCard/openStack/etc.

lock messages
delete graphic "a"
unlock messages
Have I really blocked the deleteGraphic message from being sent? Or is 
it
being sent after the messages are unlocked?

web cam capture

[Doug Lerner]

Just some general questions to the group - I notice that Revolution has
video camera capturing features. It seems that this would be hard to
implement across platforms, different camera models and different interfaces
(USB and Firewire - like iSight).

How do people find the robustness and cross-platform/cross-product usability
of the video capture features?

Does this work as well with webcams as with video cameras?

Thanks,


doug

Re: Suppressing a message?

[Doug Lerner]

I notice that, but wonder about the timing of how that works. According to
the docs, the deleteGraphic message (for example) is sent when a graphic
removed from the stack.

But when, message-timing-wise, is it removed from the stack?

If I say

lock messages
delete graphic "a"
unlock messages

Have I really blocked the deleteGraphic message from being sent? Or is it
being sent after the messages are unlocked?

Suppressing a message?

[Doug Lerner]

I found the messages that take place when images and graphics are deleted:
deleteGraphic and deleteImage (of course). I wonder why they don't appear in
the Message Watcher window though?

Anyway, one question I have it - there are two ways of deleting a message -
if I do it manually or if a handler does it. In the case of the handler, I
want to suppress the normal deleteGraphic message from being sent. Is there
a way to do that?

Thanks,

revChangeWindowSize

[rodney tamblyn]

When I call revChangeWindowSize on my PowerBook G4, using syntax such as

 revChangeWindowSize 500,700,"slide",1,1000

... the window resizes so that only the titlebar is visible (ie height 
= 0 ) It will adjust the width, but no matter what value I set  width 
(param 2) it doesn't work.

Any ideas what might be going wrong here?

Hi Chris,

There should be a way to do this on Windows via
Dynamic Data Exchange API -- here's something I copied
from a FoxPro forum a while back :

=
=ddesetoption("SAFETY",.F.)
ichannel = DDEINITIATE("myapp","ZOOM")
IF ichannel =>0
=DDETERMINATE(ichannel)
QUIT
ENDIF
=DDESETSERVICE("myapp","define")
=DDESETSERVICE("myapp","execute")
=DDESETTOPIC("myapp","","ddezoom")

PROCEDURE ddezoom
PARAMETER  ichannel, saction, sitem, sdata, ;
   sformat,istatus
ZOOM WINDOW SCREEN NORM
RETURN 

has the added advantage that, if the user starts up a
second instance the first instance gets maximized.
=

Check out the DDE-externals that Tuviah wrote ages
ago, at the old Crossworlds website :


If you need a hand converting the above xBase code
into xTalk, let me know.

Hi Dave,

Do you get the same problem if you open the Word doc
by means of the 'launch' command ?
--
  launch tFilePath with tApplicationPath
--

What command are you passing to the shell()-function ?

Re: FlashMX and Runtime Revolution

AFAIK you can't do anything with MX.  You can interact with Flash 
within a QuickTime player, but you will have to save back to Flash 5 
(for QuickTime 6), or Flash 4 (for QuickTime 5).
