"In Ubuntu, you don't do anything - the OS checks for updates and prompts the
user as needed, an experience very much like OS X."

Yes, of course standard Debian has an update manager which pops up, if you
want it to work that way.  That's how you will get it out of the box.  I
don't, I want to update what and when I want, not have it just happen. 
Richard, where do you think Ubuntu's update manager comes from???  Mandriva
has an update manager too, which I tell people also not to use, but to do
updates consciously when they are sure they want to.  

The difference between Debian and Ubuntu is what gets updated, and the
release schedule.  You are better off, for purposes of stability, with a two
year major release schedule and updates of the existing release between
them, than you are with Dozy Dragon coming out now and six months later
being followed by Loopy Leonard.  This is much closer to how both Apple and
MS work.

My point about the Rev support is this.  I don't know exactly what you could
do to STOP Rev running on Mandriva or the Slackware derivatives.  Its a
crazy idea.  It runs on them by default.  Its not that Rev has a problem
with some distros, what works on one works on all.  Its the generic level of
feature support that is the problem.

Polygonflow: clockwise or counter-clockwise?

Can you figure a smart way to check if the flow of a polygon goes

Sorry to disagree Peter, It is not just at the generic level where
there are problems.  I am assuming by the generic level you mean the
way that Rev on Linux is treated like the unloved stepchild of Windows
and OS X (developer previews meant to flush out bugs only being
released for OS X and Windows, the lack of features like revBrowser,
persistent bugs in things like revPrintField, etc).

But there are problems with distributions other than Ubuntu/Debian.
Take for example this problem reported by me concerning Mandriva (and
as mentioned by Runrev in the comments, also occurring on Suse):
http://quality.runrev.com/qacenter/show_bug.cgi?id=8513 .  And someone
was asking in the forums recently about his issues with getting Rev to
run on Mandriva -- he couldn't even get it to start (and from previous
conversations I've had with him, he was no newbie).

There are several other issues I've seen where a problem would appear
in one version of Linux, but be absent in another.  Some of them have
been reported by me in the RQCC over the years whilst I've been trying
to get Rev running on Linux.

This is why I think it is important that there is feature parity AND
at least one distribution where Rev is known to work fully.  I can see
myself how much time would be consumed cross-testing on different
distributions.  Ubuntu has not been my preferred choice over the
years, but if that is the distro they choose to support (and support
fully) then I can live with that.

If Runrev can offer a compelling development tool on at least one
version of Linux it should lead to an increased demand for Rev on
Linux.  Further down the line other distros can be added to the list
of 'fully supported' distributions.

Re: Links to programs in Windows?

[Mark Schonewille]

Hi Florian and Kresten,

You give some interesting hints, Florian, but it can't be done by  
RunRev as far as I know. One needs to do this with VBScript for  
instance. One should read out the App Paths registry key and cycle  
through all entries under the Software key. Because Revolution can  
only read data and no nodes, it can't be done. I have started working  
on a simple command line solution with VBScript, but I need to finish  
other projects first.

Sarah,

it could be an issue with SSL certificates.  I don't know if they are
using a self-generated cert that you chose to accept in your browser
some time ago (unlikely), or maybe they have a cert that came from a
source that is not recognized by Rev.

You could try switching off SSL certificate checking using this rev command:

libUrlSetSSLVerification false

before making your URL call in revTalk.  That revBrowser works might
suggest this is the problem.  I imagine revBrowser makes any http call
via the IE/Safari plugin, thus relying on their SSL handling.

If this doesn't make any difference, then it looks like they are using
some other kind of authorization than Basic.  Actually you can test
the Basic Authorization issue by loading this in your normal browser
(and seeing if you get into the page you want):

https://username:passw...@memberservices.optuszoo.com.au/myusage/

That will show whether or not Basic Authorization is acceptable.

Hopefully this enables you to identify where the problem lies.

Windows 'run as administrator' property of standalone.

[David Glasgow]

Whilst trying to solve a problem of a customer, I noticed that on Vista, a 
standalone can have a 'run as administrator' property set, which presumably 
does what it says on the tin.  My recollection is that Pre Vista this was a 
property which could be set on a shortcut, but not the standalone itself.

I was wondering whether setting this before distribution might reduce the 
occasional permissions problems which arise.  I was also slightly worried that 
user levels can apparently be so readily overridden by an executable, and also 
that there may be unforeseen (by me) adverse consequences if I set this flag 
before distribution.

So, should I or shouldn't I?

Re: Getting data from a secure web page

[Dave Cragg]

Sarah

Not quite sure what you're wanting to do. Do you just want to get the html page 
normally returned after login from within a Rev script?

If so, does this work?

on mouseUp
  libUrlSetSSLVerification false ## SEE BELOW 1
   put "https://memberservices.optuszoo.com.au/login/"; into tUrl
   put "Action=login&username=abc&password=abc" into tPostData ##SEE BELOW 2
   
   post tPostData to url tUrl
   put it into field 1
   if the result <> empty then
  answer the result
   end if
end mouseUp

Point 1
libUrlSetSSLVerification false does as Bernard says, and no check is made of 
the certificate. (But data is still sent encrypted) Better to set the 
sslCertificates to a suitable file if you have one.

Point 2
Change the "abc" for username and password to the correct values. (URLEncode if 
they contain funny characters or spaces)

When I tried it, it returned the login page again but with the "Incorrect 
username/password." text included, which suggests it might be doing something 
right. 

Good luck!
Dave

I agree :-), still

a) is also valid for developers of any other existing Linux distribution

b) if onRev server is included, then it is not limited to development, 
but can also be deployed as a server (you know LAMP, so this could be

If I try with the wrong login details, I get that "Incorrect
username/password." page, but if I use my real login details, I get no
page, but the result is "error 302 Moved Temporarily".

Bernard: Trying the web address with the username & password included
in my browser doesn't work either - I just get the login page again,
so I guess that means it isn't just basic auth.

So I will try it on Firefox and see if I can get the custom headers as
Jim suggested.

I usually do this on my work computer, so I will check tomorrow to see
if I have a certificate there.

Thanks all,
Sarah

What happens if you try "get" instead of "post"

get url 
"https://memberservices.optuszoo.com.au/login/?Action=login&username=abc&password=abc";

(Not sure about that final forward slash.)

libUrl will follow redirects (the 302 response) when using "get" but not "post"

If it won't accept "get", look in the headers returned from "post" (using 
libUrlLastRhHeaders()) and try to find the "Location:" header. With a bit* of 
luck, it will contain the URL with the data you need. (* maybe a lot of luck)

Re: Rev for Linux (was Re: iPadding around?)

[Bernard Devlin]

Actually Viktoras, it might not be as much work as at first seems.

OpenSuse have now produced a system whereby one can choose to build
one's own version of Linux "in the cloud".  When all the configuration
is done, the distro can then just be downloaded and installed.

It is certainly within the realms of possibility that RunRev could
produce a linux distribution that worked and included Rev in it.

Anyone who decided to go with that distribution could then connect to
OpenSuse repositories (or even set up an OpenSuse DVD as their own
local repository) and add additional packages to their own
installation.

I believe this might still not be the solution that Linux users like Peter want.

Whether or not RunRev could use the same distro on their on-rev
servers depends on their service provider.  As I've got a hunch that
Rev is using Linode for on-rev, then I can say that I know
definitively that it is possible to run one of these OpenSuse distros
on Linode.com

Hi David

On Vista always have to run Valentina Studio with "run as
administrator" or I get errors.

I would be surprised if you choosing to set such a flag on an
executable would result in that information being carried over when
the executable is copied to another system.

Re: Noise in Windows icon when standalone compiled on Mac

[David Glasgow]

Bill,

I got quite excited about this, because I have struggled to get nice looking 
Windows icons.

The Mac icon generated by iconverticons.com was fine, but the Win version 
choked the Rev standalone builder "does not include 6 blah blah blah".  I have 
encountered this lots of times with icons from various tools purporting to 
generate valid Windows icons
So I imported it into Iconographer, and chose 'complete icon' from the icon 
menu, and it did some stuff.  The resulting icon is now acceptable to Rev at 
build time, but doesn't look good on Vista, and behaves as if some sizes are 
missing (they're not, as far as I can tell).

Why are icons so blimmin' tricky?

Re: Polygonflow: clockwise or counter-clockwise?

[Jeff Massung]

Michael,

I assume you are talking about 2D polygons...

Just take a 3D cross product of the first two vector (P3 - P2) x (P2 - P1).
If the resultant vector is coming out of the screen (Z < 0) then the polygon
is counter-clockwise. If it is going into the screen (Z > 0) then the
polygon is clockwise.

http://chortle.ccsu.edu/VectorLessons/vch12/vch12_1.html

That page may be of help if you don't know what the cross product is. Note:
to do the 3D cross product, just use Z=0 for all the points.

released for OS X and Windows, the lack of features like revBrowser,
persistent bugs in things like revPrintField, etc).


At the risk of soundy all FOSSy, is the problem with the scripted

address?


As for RevBrowser, I'd love to see that for Linux too.  As an external, 
the code is separate from the main code base and so the Linux verison 
could conceivably be farmed out.


I would be willing to toss in a few bucks toward that.  Anyone else

Okay, for anyone who is interested, the trick to adding and dropping  
tables (or executing any odd sql) when using sqlYoga is that you  
have to tell sqlYoga that the schema has changed.


The db schema that SQL Yoga caches shouldn't affect running random SQL  
commands. The schema is used when you work with SQL Query and SQL  
Record objects.


The easiest way to do that is reset the schema with dbschema_reset,  
then reconnect to the database. JUST reconnecting will NOT reload  
the schema causing you all kinds of headaches in the future.


   dbschema_reset thePriDB
   dbconn_disconnect thePriDB
   dbconn_Connect thePriDB


You should use dbobject_reloadSchema for this.

http://www.bluemangolearning.com/revolution/docs/sql_yoga/api_docs/Documents/stack_libSQLYoga_command_dbobject_reloadSchema.htm

You can find more info about the schema in the lesson "Introduction to  
the Database Object and Database Schema":


http://revolution.screenstepslive.com/spaces/revolution/manuals/sqlyoga/lessons/6870-Introduction-to-the-Database-Object-and-Database-Schema

Also, any queries you use with sqlYoga will AUTOMATICALLY reconnect  
to the database.


SQL Yoga looks for the MySQL has gone away error and tries to  
reconnect to the database automatically before returning an error.


BUT if you are using the REV IDE to execute what I will call  
"foreign" queries, that is queries not run through sqlYoga, AND your  
connection has timed out, you will have problems, SO...

I now use dbconn_connect before executing "foreign" queries.

   put "DROP TABLE 'myhostname'.'mytablename'" into theSQL --  
foreign query

   dbconn_Connect thePriDB -- make sure we are currently connected
   put dbconn_get("connection id", theConnection, theDBObject) into  
theID -- get the current dbid
   revExecuteSQL theID, theSQL -- shoot the wild ass (just checking  
to see if you are reading the comments)


As I mentioned in the previous email you can use dbconn_executeSQL  
here which is easier.



   -- now reload the schema
   dbschema_reset thePriDB -- wipes the database object clean
   dbconn_disconnect thePriDB -- may not need to do this...
   dbconn_Connect thePriDB  -- this will reload the schema
   dbobject_save thePriDB -- ALWAYS SAVE YOUR OBJECTS!


Your code here can be:

dbobject_reloadSchema thePriDB
dbobject_save thePriDB -- ALWAYS SAVE YOUR OBJECTS!

Note that SQL Yoga is going to query your database again to get all of  
the table information. This means you should do this after finishing  
all alterations to your database.

If it won't accept "get", look in the headers returned from

lockLoc OR LockSize? (but not both)

[Mark Swindell]

Is there a  property for locking just the size of an object while allowing a 
manual move?  Setting the lockLoc to true does locks down both size and 
location.  

If it isn't possible do each individually, why is that?  Shouldn't it be 
possible?

Thanks,

But then it isn't standards compliant. :-)

From rfc2616

"If the 302 status code is received in response to a request other than GET or 
HEAD, the user agent MUST NOT automatically redirect the request unless it can 
be confirmed by the user, since this might change the conditions under which 
the request was issued."

The server should really return 303 for these cases.

But I think most browsers redirect using GET on 302.

This is possible.  You can move locked objects with arrowkeys  (1 and 10
pixel increments using shift), and you can reposition an object by script,
such as using the "grab" command or using a custom drag routine, ie

That is why I installed a callback when I implemented it :-)

Basically a developer registers a callback for 301, 302 and 307 by  
issuing the command libURLSetFollowRedirectCallback. libURL then sends  
the message and the developer returns a value. If it is "redirect"  
then libURL redirects. If it is "get" then libURL fetches the new URL  
using "get". Any other value performs default libURL behavior which  
returns "socket closed before end of file".

Re: Rev for Linux (was Re: iPadding around?)

[Andre Garzia]

Hello Folks,

arriving late on the thread.

I used many linux distros till I finally settled on OpenSUSE 11.2. I find
Ubuntu very charming and used it from Gusty Gibbon till Karmic Koala (can't
remember version numbers but I love those silly names, was waiting for
hungry hippo), it was fun to use and it was the first Gnome desktop that I
could actually understand, me being a KDE person from the start. What moved
me away from ubuntu was the mess that is sound under linux, it is a hit or
miss, or it works or you're in very murky waters. PulseAudio, ALSA, OSS,
they are all crap and conflict with each other. Video cards are also
cumbersome, my PC has an onboard intel chipset that till today is not well
supported. When I tried openSUSE, it just worked out of the box both video
and sound. It was more polished than ubuntu for me, I really liked their
gnome theme.

It was somewhat a struggle to move from apt to zypper but they work
basically the same, the package names change though and that is the hard
part. Revolution works well on OpenSUSE and with that in mind, I decided
that SUSE was the way to go for me.

Now on the topic of creating our own distro, I did that! I created "Andre
SUSE Distro" using Suse Studio service. Suse Studio is the most awesome and
elegant web service I ever seen. It basically allow you to choose from
multiple packages and everything, to configure all you want and then it will
build you an ISO or a VMWare image. You can even try your system online thru
a web VNC session, you don't even need to install it at home. Using this
system I created an almost barebones version of suse that would pack
RevEnterprise and RevWeb (that old alpha one). I haven't told anyone about
it because it packs RevEnterprise with my license, I made this system
basically for my own consumption, it allows me to move from bare bones pc to
fully configured and ready linux with a single DVD.

http://susestudio.com/

If people here are so inclined, I can try to build a simple suse that would
bundle Rev without a license (so you would need to put a license on first
run) and some useful tools. You could run it as a virtual machine under
vmware or virtualbox and thus test your software under linux without the
need to a full linux hardware.

:D

Cheers
andre

Re: Rev for Linux (was Re: iPadding around?)

[Bob Sneidar]

I guess the upshot of this whole discussion is that everything is a tradeoff. 
To gain stability we have to lose some freedom. The most stable government is a 
dictatorship, where only one man's wishes are done and everyone complies with 
the standard he issues. But of course, nobody wants that. Excepting the 
dictator of course. :-)

Same thing with software and operating systems. People have complained against 
the rigid control Apple maintains on development of their operating systems 
(Microsoft is no different) and hardware, but the end result is stability and 
predictability (not perfection I know). So it's all about balance. How much 
freedom are we willing to give up for stability and predictability in our 
computing world? The answer is different for every person. 

For me, and IT guy, I am willing to give up a LOT of freedom, and restrict the 
freedom of my users, so that my job does not become orders of magnitude more 
complex and overwhelming. For the guy whose computer is his own personal 
digital erector set, he will give up very little freedom. 

For me, I am willing to go with the OS that the most developers will tackle, 
because they know it's not a moving target. I am rewarded with software like 
Runtime Revolution. But the erector set guy has to face the likelihood that 
mainstream software is not going to be available for his system. He will have 
to choose from the offerings of other erector set guys (and very talented and 
productive ones I admit.)

Re: lockLoc OR LockSize? (but not both)

[DunbarX]

Is this so that one doesn't inadvertantly grab a handle and change the 
size?

You can set a custom property and trap the resizecontrol message, I guess:

The "lockrect" property might be something like "82,23"

on resizecontrol
set the width of me to item 1 of the lockRect of me
set the height of me to item 2 of the lockrect of me
end resizecontrol

It won't actually lock the rect when dragging a handle, but at least 
restores it when you stop.

I tried this with mouseMove, and sometimes it worked. But now I always get 
recursion timeouts.

I am no genius, the guys at SUSE (Novell??) are. They made the software, I
am just using it.

Speaking of software, suse studio is giving me error 500 as of half an hour
ago. Must be overwhelmed, as soon as I it is up and running I will try to
cook something.

Now, a simple pool, for those wanting a linux image for testing, how big it
could be, meaning what is the upper size limit that you would download.

Anyone here remembers what are Rev Linux dependencies:
* Pango?
* all g libs?
* qt?

and sound. It was more polished than ubuntu for me, I really liked  
their

gnome theme.

It was somewhat a struggle to move from apt to zypper but they work
basically the same, the package names change though and that is the  
hard
part. Revolution works well on OpenSUSE and with that in mind, I  
decided

that SUSE was the way to go for me.

Now on the topic of creating our own distro, I did that! I created  
"Andre
SUSE Distro" using Suse Studio service. Suse Studio is the most  
awesome and

elegant web service I ever seen. It basically allow you to choose from
multiple packages and everything, to configure all you want and then  
it will
build you an ISO or a VMWare image. You can even try your system  
online thru
a web VNC session, you don't even need to install it at home. Using  
this

system I created an almost barebones version of suse that would pack
RevEnterprise and RevWeb (that old alpha one). I haven't told anyone  
about

it because it packs RevEnterprise with my license, I made this system
basically for my own consumption, it allows me to move from bare  
bones pc to

fully configured and ready linux with a single DVD.

http://susestudio.com/

If people here are so inclined, I can try to build a simple suse  
that would
bundle Rev without a license (so you would need to put a license on  
first
run) and some useful tools. You could run it as a virtual machine  
under
vmware or virtualbox and thus test your software under linux without  
the

need to a full linux hardware.

:D

Re: Rev for Linux (was Re: iPadding around?)

[Brian Yennie]

One possibility for RevBrowser would be to build an alternative using WebKit 
(aka Chrome, Safari engine). That would allow for the same browser engine on 
all 3 platforms, instead of locking down projects to the lowest common 
denominator (i.e., IE). It would certainly support Linux as that is the 
"original" platform.

Beside Linux support the one thing that has kept me nervous about using 
RevBrowser is that it comes with the usual cross-browser issues!

RE: How do I resize a group when using 'grab'?

[Hugh Senior]

Q: How do I update the dimensions of a group when I 'grab' a control?

'Grab' is a really simple way of moving an object in 'browse' mode: Just
'grab me' in a mouseDown, and the object tracks the mouse until mouseUp (see
the docs).

There is, however, a problem when you 'grab' a control in a group. The
dimensions of a group do not automatically change to fit the repositioned
control, nor is the group's formattedRect updated. This means you can easily
drag an object out of sight to an inaccessible position. This is a 'bad
thing'.

It took me a while, but the trick here is to understand that the
formattedRect of the containing group is only updated when a geometric
property of a control (top, bottom, left, right, width, height etc) is
changed. The following is a simplified group script:


This fails to update the rect of the group...
  on mouseDown
--| User clicks and drags a control in the group
grab the target
  end mouseDown

  on mouseMove
--| Resize the group...
set the rect of this group to the formattedRect of this group
  end mouseMove


This works...
  on mouseDown
grab the target
  end mouseDown

  on mouseMove
--| Force the formattedRect to update...
set the top of the target to (the top of the target)+1
set the top of the target to (the top of the target)-1
--| Now the group can be resized...
set the rect of this group to the formattedRect of this group
  end mouseMove



Maybe this will help someone searching the archives.

How do you tell Rev to do something useful via applescript?

I tried

tell application "Revolution Media"
activate
   --would like ideally first to: do script "go stack " & quote & 
"Foo" & quote & " in a new window"
   --but I couldn't even get the next command to work if the stack 
was already open and frontmost

   do script "create card"

Nothing happens other than activation. While I'm asking, the next

This is what worked for me. I was running Leopard (10.5.2) on a Power PC, and 
using Revolution 2.8.1 when I wrote these instructions. Assume they still work 
today.

1. Open Revolution
2. File / New Mainstack
3. Object / Stack Script
4. enter the following script

on barklikeadog additionalStuff
  return "arf arf" && the seconds && additionalStuff
end barklikeadog

5. Apply, close the stack script
6. Object / Stack Inspector
   Name: AppleEventCatcher
7. close the inspector
8. File / Save
9. File / Standalone Application Settings
10. Windows
   Build for: (de-select the checkbox)
11. close the Standalone Application Settings window
12. File / Save
13. File / Save As Standalone Application
14. Quit Revolution
15. in the Finder, go to the newly created Mac application "AppleEventCatcher" 
and with the control key down, click on the application. Select "Show Package 
Contents"
16. Go to Contents / Resources / Revolution.rsrc and change the name of that 
file to AppleEventCatcher.rsrc
17. close the Show Package Contents window
18. Open Apple's Script Editor.
19. In the script window enter the following script:

property thescript : []

on run
copy "barklikeadog beg" to thescript
tell application "asdfgh"
activate
do script thescript
end tell
end run

20. Don't press the Compile button.
21. File / Save and it will ask you where asdfgh is located. Select the newly 
modified Mac application "AppleEventCatcher"
22. Press the Run button
23. The Result window should display something like:
"arf arf 1206236082 beg"

From what I can see, the communication style I am using does not permit more 
that one word to be sent from the Script Editor to the application. My way 
around that is to URLencode what I wish to send and then URLdecode in the 
application. I don't know what kinds of payload limits there are going to and 
coming from the application.

Hi Emmett,

It is not necessary that the stack be at the frontmost to make it
react with applescript. Simply specify the stack you need as follows:
tell application "Revolution" to do script "create card to stack \"TheSlugLab\""

Try this:

tell application "Revolution"
do script "if the clipboard is text then
 go cd \"MyCard\" of stack \"TheSlugLab\"
 select text of fld \"MyField\"
 paste
 send \"mouseUp\" to btn \"MyButton\"
 end if"

I wouldn't count on compiled apps. Both OS versions you mentioned have moved

Re: Polygonflow: clockwise or counter-clockwise?

Michael,

I assume you are talking about 2D polygons...

Just take a 3D cross product of the first two vector (P3 - P2) x (P2 - P1).
If the resultant vector is coming out of the screen (Z < 0) then the polygon
is counter-clockwise. If it is going into the screen (Z > 0) then the
polygon is clockwise.

http://chortle.ccsu.edu/VectorLessons/vch12/vch12_1.html

That page may be of help if you don't know what the cross product is. Note:
to do the 3D cross product, just use Z=0 for all the points.

  
Well, I confess I don't properly remember what the cross-product is, so 
I will go read that page.


But even without doing so, I am sure that this can't be a correct 
solution; the following two polygons have opposite flow, but P1, P2 and 
P3 are the same


0,0; 100,0; 100,100; 0,0(i.e. a counter-clockwise triangle)
0,0; 100,0; 100,100; 200,100; 200,-10; 0,-10; 0,0   (i.e. a clockwise 
L-shape)


I'll post a couple of suggested solutions shortly (once I've got the 
stack running properly)

Hypercard import ?

[Pierre]

I'm using Rev/enterprise  version 4.5.0. with Leopard X.6.2 on a MacPro.
I would like to convert an old Hypercard stack to Runrev.
I did it a few years ago with an old version of Rev.
I can't do it today.
I can't open the stack directly from Rev, the stack isn't seen from Rev.
I can't change the "Open with" of the 'Information Window' from Hypercard to 
Revolution.

My question is:  "Can Rev V.4.5  open and convert an hypercard  Stack ?"
What are the solutions to do it ?

Many thanks to any one who could give me an idea

I think this is an interesting proposition.  Although my understanding
is that when Apple made their modifications to Konqueror, they
returned the changes "as one large tarball".  I think that meant that
no-one in the Linux world has re-integrated the changes.

Where Chrome sits in relation to WebKit, I'm not sure.  I don't know
if Google took Webkit and built on that.

I'm just re-iterating Peter's long-standing problems with Rev on
Linux.  I've never managed to get Rev working long enough to get
anywhere near trying to print things out.  My problems have been at a
far more basic level than that.

If Peter does not repeat his problems here, I'll look through the list
and RQCC and try to produce a summary.

Re: lockLoc OR LockSize? (but not both)

[Mark Swindell]

That's what I thought, but wanted to be sure I wasn't missing something obvious.

It makes no sense (to me) to have these be a joint property. They are two 
separate things.  

Example: I have several images I want to drag around and reposition on a card, 
but I also want to constrain their size to 200,200.  It would be nice to be 
able to do this in the IDE without the risk of images blowing up all over the 
place.  (Returning from editing a group, for example... surprise!)

Is there some structural reason within Rev that the status quo has to be as it 
is?  If not, this strikes me as a good feature enhancement... why not have two 
separate properties... what do others think?

Re: Polygonflow: clockwise or counter-clockwise?

[Jeff Massung]

Michael,

Sorry, but the problem you are running into is that (in your second example)
you are working with a concave polygon instead of convex. I promise, using
the cross-product is correct.

Concave polygons get tricky, because the winding actually does - in fact -
change direction. You - as a human - are simply looking at the resulting,
whole polygon and making a determination from that, which is actually
wrong.

You have a couple options:

1. Perform the cross product across all points from last to first - exactly
as I originally described, and count the winding directions of each, taking
the greater of the two.

2. If you know the majority of your polygons are shaped a particular way, an
often-used trick is to take P(N), P(2), and P(1) and simply use those as a
quick and dirty test.

Option #1 will produce the desired, correct result, but takes more time.
Option #2 can very often be wrong, but given your use-cases could be right
100% of the time.

Re: Polygonflow: clockwise or counter-clockwise?

Michael,

Sorry, but the problem you are running into is that (in your second example)
  

The examples were from me (Alex) not Michael :-)

you are working with a concave polygon instead of convex.
Yes. Exactly. There *are* polygons which are concave. We could all look 
at them and agree on where the inside of the polygon is, and therefore 
all agree on whether the perimeter is defined clockwise or 
anti-clockwise around that interior.

 I promise, using
the cross-product is correct.
  
If you define the problem space to be limited to convex polygons, then 
it is correct. But if you want to handle all (or almost all - see below) 
polygons, then it is not correct.

Concave polygons get tricky, because the winding actually does - in fact -
change direction. You - as a human - are simply looking at the resulting,
whole polygon and making a determination from that, which is actually
wrong.

  
The conclusion that you arrive at from looking at the whole polygon is 
correct; the winding around the interior is consistent; the direction 
change in co-ordinate space changes, but not relative to the interior.

You have a couple options:

1. Perform the cross product across all points from last to first - exactly
as I originally described, and count the winding directions of each, taking
the greater of the two.

  
Sorry, that doesn't work consistently either. Picture a regular 12-sided 
figure, with two sides vertical, and defined counter-clockwise. The c-p 
will give the same answer for all 12 vertices. Then draw a much larger 
square around it, such that one of the vertical sides of the square 
overlaps the vertical side of the shape (and the square encloses the 
shape). Now "erase" the line segment which is shared - we now have a 
16-sided figure, and let's define it in the order that the points from 
the original 12-sided figure remain counter-clockwise. (Note that the 
area inside the original figure is now outside this new figure). This 
new  figure is actually (according to humans :-) defined clockwise - but 
the c-p will still give the same answer for all those original points, 
so it would have 10 saying counter-clockwise, and only the 6 new ones 
would say clockwise - and hence get the wrong answer.

2. If you know the majority of your polygons are shaped a particular way, an
often-used trick is to take P(N), P(2), and P(1) and simply use those as a
quick and dirty test.

Option #1 will produce the desired, correct result, but takes more time.
Option #2 can very often be wrong, but given your use-cases could be right
100% of the time.
  

Option #1 gives unreliable answers in some cases, such as the example above.
Option #2 gives very unreliable answers

And there are simple (though not super-fast) solution that get the 
answer correct (i.e. agreeing with what a person would say) for all 
cases where people would agree.


There are more complex cases (e.g. self-inverting polygons, which you 
could argue are malformed polygons) where there is probably no correct 
answer.

Lol, I noticed that just as I hit "send" ;-)

Yes. There are insane cases for which there may - in fact - be no correct
answer (especially if the polygon does intersect with each other... at which
point the debate begins on the definition of "polygon" beyond just being "an
n-sided object").

Neither of us can say what Michael's original use cases are/were, and
hopefully the cross-product solution works for him just fine.

The options I gave for concave polygons (assuming no intersections) do work
and are used in tessellation algorithms and elsewhere. There's no need to
complicate the solution w/o even knowing if the problem warrants it. ;-)

I'll post a couple of suggested solutions shortly (once I've got the 
stack running properly)


There are two approaches (at least) that consistently get the same 
answers as we all intuitively "know" are correct.


By AREA.

Calculate the (signed) area between each edge and some baseline (i.e. 
the area enclosed by the edge itself, its projectino onto the baseline 
and the two projection lines). Sum this area for all edges. Looking at 
whether this is positive or negative gives an answer.


By Point.

Find the leftmost, lowest point (**). (i.e. the one with the lowest X 
value, and of all those having the same X value, the lowest Y value).
(Note that this same point (value) can occur multiple times in a 
polygon, due to self-intersection or self-overlapping polygons - this 
doesn't matter, just pick any of those points).  Looking at the previous 
and next points, determine the change of direction implied for these two 
edges (you could use the cross-product to do this, or simply normalize 
and compare the gradients).


(**) - this description assumes 'normal' cartesian coordinates. Beware 
that RunRev uses a coordinate system where the vertical axis is 
"upside-down", so increasing Y values are associated with moving downawards.


Some sample code - adopted from elsewhere (and translated into revtalk) 
- with only moderate testing, but I'm fairly confident I converted it 
fairly accurately.

(It's a bit wordy, but seemed clearer that way).

Re: Getting data from a secure web page

[Sarah Reichelt]

OK, I think I'm going round in every decreasing circles but I
thought I would describe the steps I am taking, in case anyone else
found it useful.


Using Firefox and Firebug to check what is going on, I see the following:

I connect to .
I enter my details and these get POST'ed.
The result is a 302 that redirects to
, using GET with no
parameters.
This page has the data that I need.

As far as I can see, there are no authentication headers, although
there is response header: "Set-Cookie:global_auth=".

But checking the request headers for the second page (after the 302),
I see that there was a header:
"Cookie:JSESSIONID=444F4BE5150F4897E7B2A88BB12E7D5D; global_auth=..."

Not surprisingly, the global_auth section of the Cookie matches
global_auth section of the Set-Cookie response from the original page.
The JSESSIONID seems to be generated by the browser as part of the
original request.

Setting the httpHeaders to this and using
get URL "https://memberservices.optuszoo.com.au/myusage/";
with no user name & password supplied, did give me the data I
needed sometimes :-(


Both the JSESSIONID and the global_auth vary on repeated tests,
although I can see my user name embedded in the global_auth, as well
as a consistent set of numbers that is presumably my password
encrypted.

I have found that sometimes I get a JSESSIONID returned as part of the
libURLLastRHHeaders() from the login page, and sometimes I get the
global_auth. But I haven't been able to predict what I will get. If I
don't get the global_auth, then even using a previous JSESSIONID &
global_auth does not seem to work.

Sigh.


Trevor, I downloaded your framework and got the modified libURL, but
the stack won't open - it says it is corrupt. I wonder is this due to
the multi-dimensional arrays stored as custom properties bug?
I opened the stack in a text editor and copied the scripts into a new
stack and tried using it instead, but not even a basic "get" worked
then, so I can't have done that right.

So a few questions for Trevor:
- is there a version of your libURL that opens in Rev 4.0 or 4.5?
- how do I make it the default instead of the current one?
- how do I set up the callback? I am familiar with using callbacks for
the asynchronous FTP commands but then I create a handler that gets
the callback message and processes it. What do I need to do in this
callback handler to make it follow the redirect?


Jim, I found your earlier thread about this sort of thing, but even
following your advice about headers, I still can't get it to work
reliably.

Thanks everyone for your patience and helpful suggestions.

Cheers,
Sarah

On-Rev Long Delays (final pass)

[Bob Sneidar]

Hi all. 

I am going to make one more attempt at this before I drop it. When I try to 
execute queries against the on-rev mySQL server, and there has been a long 
period of idle time, the query takes a very long time to execute, and in the 
end the query fails. Even a simple query like "SHOW TABLES" will fail so I know 
it is not my Sequel that is the problem, and anyway, when I copy/paste my 
Sequel to an SQL utility, it works famously. 

It is my opinion that on-rev does not respond to queries made with a dropped 
connection, even to report an error. Normally a local mySQL server would return 
some kind of error, but I believe that the on-rev site has a mechanism, perhaps 
to prevent a brute force attack, whereby it will not respond to bad 
connections. 

If anyone can confirm or deny this theory it would help me sleep much better. 

Bob

The custom version of libURL is actually a plain text document. Here  
are the instructions for installing it:


http://revolution.screenstepslive.com/spaces/revolution/manuals/glxapp/lessons/5615-How-Do-I-Install-the-Custom-Version-of-libURL-

This version of libURL will also handle cookies for you seamlessly.


So a few questions for Trevor:
- is there a version of your libURL that opens in Rev 4.0 or 4.5?
- how do I make it the default instead of the current one?


See instructions.


- how do I set up the callback? I am familiar with using callbacks for
the asynchronous FTP commands but then I create a handler that gets
the callback message and processes it. What do I need to do in this
callback handler to make it follow the redirect?


libURLSetFollowRedirectCallback registers a callback:

libURLSetFollowRedirectCallback pMessage, pObject

Just pass the name of the message that should be sent and the long id  
of the object the message should be sent to. If no object is specified  
then it is assumed the callback message is in the message path.


From the callback you should return "redirect" if you would like to  
try the POST again using new url. Return "get" if you want to GET the  
contents of the new URL. Return anything else to let libURL do what it  
would normally do.


libURLSetFollowRedirectCallback "RedirectRequestCallback", the long id  
of stack "MyStack"


command RedirectRequestCallback pMethod, pURL, pStatusCode, pRedirectURL
-- return "redirect" or "get" or empty
end RedirectRequestCallback

Thanks for all this Trevor. I installed your custom libURL fine thanks.

It now redirects but it doesn't get me where I want, instead I get:
You must be logged in with a parent account to
access this functionality.

So progress, but still not there

ANN: Hinduism Today Navigator - Alpha Test Open

[Sivakatirswami]

Namaste, Aloha and "Oi" from Kauai, Hawaii and Niteroi, Brazil:

Hinduism Today and Andre Garzia are happy to announce that the latest 
incarnation of Hinduism Today Digital Edition has been released under a 
new name:


Hinduism Today Navigator

I want to thank both Andre for his hard work on this and Trevor DeVore 
for the brilliant additions to our RunRev world, the data grid, SQL yoga 
and GLX that Andre used to build this and RunRev for the new graphic 
effects which finally make people say "Wow, it's beautiful!"  And to 
Jerry Daniels for making development process with tRev, so "sweet".


We would like anyone who has time to hammer hard on this one:

http://www.hinduismtoday.com/modules/wfchannel/index.php?wfc_cid=29

FYI: this is a broadband product (free)  We bundle a lot of content with 
the standalone, for a 30MB download, after that, online line 
transactions are small unless you ask for a  PDF.


Send any "no holds barred" feedback  to

ka...@hindu.org
an...@andregarzia.com

Sorry, no Linux version: our media player requires Flash to run inside 
the RevBrowser window.


I'm calling this a beta version but Andre prefers "alpha" -- in case you 
find any bugs then we can just say:


"Well, its an alpha version after all... " (smile)

but in house tests on 8 different Macs and 10 different Windows users 
all look good so we are widening the test group to include all RunRev'ers.


All the best from Chilly Kauai. When I went for a swim in the Wailua 
this morning, air was about 54 and the water 65... that's about as cold 
as it gets here.


Thank you for taking the time to try it out.

Sivakatirswami

ps. Is anyone seeing the 20 pixel "menu shift" bug? appears as a strip 
of background at the bottom of the stack/card that should not be there.


And if anyone is connecting through a proxy, we would like to know that 
is working.

RE: Links to programs in Windows?

[Jim Bufalini]

Kresten,

The quickest way on a PC would be to use the registry because it is in
memory. But, if you are not comfortable with this, you can get a complete
list of all "installed" programs on a PC by walking down the Program Files
directory and all of it subdirectories and looking for .exe files. I don't
think you are going to find what you are looking for where you are looking
because even if it exists, it would contain .lnk files which are shortcuts
themselves.

Here is some code you could use to get a list of all EXE files on XP and
Vista/7. It can take a while (many seconds on a large system) because for
example, in my case there are almost 20,000 directories to search because
you cannot look at just the root directories under Program Files because
programs like Word are in sub-sub-directories. 

You will also probably end up with a much larger list of programs than you
need, so you will probably want to add filters by say having a list of
directories you are interested in and skip entire directory trees if they
are not on your list. But any way, this following code will give you all
programs on a PC. You can modify it with filters to shorten its search. I
didn't use recursion, because you can easily hit the recursion limit.

local sFolderList, sProgramList, sCnt

ON mouseUp pMouseBtnNo
put 0 into sCnt
put empty into sFolderList
put empty into sProgramList
GetAllExecutables
REPEAT WHILE line 1 of sProgramList <> "Done"
  -- Necessary because not using recursion
wait 0 milliseconds with messages 
END repeat
put sProgramList -- Test line can be removed
delete line 1 of sProgramList
-- Do any processing of sProgramList here
END mouseUp

ON GetAllExecutables pCurrentFolder
local tRootFolder, tFileList, tSubFolderList

put "C:/Program Files/" into tRootFolder
IF sFolderList is empty THEN
SET the defaultfolder to tRootFolder
put URLDecode(the folders) into sFolderList
filter sFolderList without ".*"
-- You can filter other directories out here
put line 1 of sFolderList into pCurrentFolder
END if
IF pCurrentFolder is empty THEN exit GetAllExecutables
IF char -1 of pCurrentFolder <> "/" THEN put "/" after pCurrentFolder
SET the defaultfolder to (tRootFolder & pCurrentFolder & "/")
put the files into tFileList
filter tFileList with "*.exe"
filter tFileList without "uninstall*"
REPEAT FOR each line tFile in tFileList
put (the defaultFolder & "/" & tfile) into line (the number of lines
in sProgramList +1) of sProgramList
END repeat
delete line 1 of sFolderList
put URLDecode(the folders) into tSubFolderList
filter tSubFolderList without ".*"
IF tSubFolderList <> empty THEN
REPEAT FOR each line tSubfolder in tSubFolderList
put pCurrentFolder & tSubFolder & "/" & cr before sFolderList
END repeat
END if
IF sFolderList is empty THEN 
put "Done" & cr before sProgramList
exit GetAllExecutables
END if
put line 1 of sFolderList into pCurrentFolder
-
add 1 to sCnt -- Test line can be removed
put sCnt -- Test line can be removed
-
send "GetAllExecutables" && pCurrentFolder to me in 0 milliseconds --
