I've always managed the CRs as it's fairly easy and I guess I've never
really thought about it. I've not seen your solution before, but I like it.

Thanks for the tip :-)

Yes. Even though I said I do it all the time, something I have never done is
use a single char variable or custom property name. The reason for this is I
preface all vars with either "g" (global), "s" (script local - some people
use "l"), "k" (constant), "t" (meaning "the" or "this" - handler local) or
"p" (parameter). And "c" (custom property set), or "u" (user single custom
property). So it would have to be at least 2-chars and in your case it would
have been *put the uX of... into tX. If it were a custom property set, it
would have been *put the cX["uX"] of... into tX.

As you can see, using conventions like this, automatically preclude the
issue you encountered. But since I was testing to see if there was a problem
with a 1-char custom property, I used your X, Y and Z. And I didn't use a
behavior in order not to confuse the issue.

Also, I automatically removed the spaces in the card names because as
Jacquie pointed out both First and Card are reserved words, but in general,
you make yourself vulnerable to these kinds of issues, if you use common
single words to name objects and vars.

I also prefix everything like handler and object names. This is not common,
and some are critical of the extra keystrokes, but I find, it eliminates the
possibility of my handlers or objects being named the same as another stack
in memory. And, as many know, I am a proponent of explicit vars (but I won't
get into that ;-).

Also, use of parenthesis to force resolution, while not necessary, is
another good practice and usually makes code more readable such as: 

*put "this is a line" into line (the number of lines of fld "MyField" + 1)
of fld "MyField*

You could use *put "This is a line" after...* but then you have to manage
CRs. The parenthesis above force resolution to a number first and, I think,
makes the statement more readable.

Bottom line, all of the above saves hours of debugging time for both you and
others in the long run. And, if you use verbose variable, handler and object
names, you save even more time and memory strain, six-months down the line,
when you go to make a simple change to the code.

RE: Problem Calling Custom Card Props with the Same Name Using Switch

[Gregory Lypny]

Hello Jim and Jacqueline,

Jim, I've no problem with your quick answer.

The Rev tech people have resolved the issue (see below), giving a very good 
answer.  It turns out that the problem arises when the variable that receives 
the value of the custom prop has the same name as the custom prop and not, as I 
originally thought, that the same custom prop name is used for multiple 
objects.  Recall that I had used

put the y of this card into y,

where both the custom prop and the variable have the same name, in addition to 
that name being used for custom props on other cards.  I think both of you, as 
well as others on the list, were able to create stacks where the problem does 
not occur because you gave your custom prop a different name from the receiving 
variable, such as

put the cy of this card into y,

so in those instances, my original example was not replicated, but the answer 
lay hidden in yours.

Glad that it's resolved, and thanks to everyone for taking such a thoughtful 
look at it!

Regards,

Gregory

I was wondering about this too. In my (successful) tests, I also renamed 
the cards. The word "first" is a reserved word, and "first card" is a 
valid card reference, so I was wondering if the engine was getting 
confused about that. A better naming strategy would be to avoid use of 
reserved keywords in card names and then try testing again.

I gave a very quick answer to you because I do this all the time and, in
fact, ListMagic has identically named custom property sets in the stack(s)
and in each card that you install ListMagic widgets in. If what you say were
true, ListMagic would not work at all.

So I created a stack, added two cards called FirstCard and SecondCard (I
don't like spaces in names) and in cd id 1002 I created a button with the
following script:

ON mouseUp pMouseBtnNo
set the x of cd "FirstCard" of this stack to "123"
set the y of cd "FirstCard" of this stack to "456"
set the y of cd "SecondCard" of this stack to "ABC"
set the z of cd "SecondCard" of this stack to "DEF"
END mouseUp

I then put a button and a field called "fldResult" on FirstCard and
SecondCard. The button has this script:

ON mouseUp pMouseBtnNo
local tX, tY, tZ
-   # 
put the short name of this card & cr & the long name of this cd into fld
"fldResult" 
SWITCH the short name of this card
CASE "FirstCard"
put the x of (cd  the short name of this card) into tX
put the y of (cd  the short name of this card) into tY
put return & "x" && tX && "y" && tY after fld "fldResult"
break   # 
CASE "SecondCard"
put the y of (cd  the short name of this card) into tY
put the z of (cd  the short name of this card) into tZ
put return & "y" && tY && "z" && tZ after fld "fldResult"
break
DEFAULT
put cr & "Error: It's neither card" into fld "fldResult"
END switch
END mouseUp

On FirstCard I get:

FirstCard
card "FirstCard" of stack "D:/MyStacks/TestCProps.rev"
FirstCard
x 123 y 456

And on SecondCard I get:

SecondCard
card "SecondCard" of stack "D:/MyStacks/TestCProps.rev"
y ABC z DEF


Seems correct to me. ;-)

There is no problem except readability and maintainability of code in using
1 char custom properties and vars. When you experience weirdness like you
are seeing, first put to a field in your stack rather than the msg box to
eliminate any possibility of the msg box contributing to your issue and then
change excessive use of *this* stack or *this* card to something more
specific. Also use parenthesis to resolve a name like a card name first.

END mouseUp

I then put a button and a field called "fldResult" on FirstCard and
SecondCard. The button has this script:

break   # 
CASE "SecondCard"
put the y of (cd  the short name of this card) into tY
put the z of (cd  the short name of this card) into tZ
put return & "y" && tY && "z" && tZ after fld "fldResult"
break
DEFAULT
put cr & "Error: It's neither card" into fld "fldResult"
END switch
END mouseUp

On FirstCard I get:

FirstCard
card "FirstCard" of stack "D:/MyStacks/TestCProps.rev"
FirstCard
x 123 y 456

And on SecondCard I get:

SecondCard
card "SecondCard" of stack "D:/MyStacks/TestCProps.rev"

RE: Problem Calling Custom Card Props with the Same Name Using Switch

[Gregory Lypny]

Hello Jacques, Jacqueline, Craig, and Jim,

Sadly, it is a bug then.  The consequences, as I said, are potentially serious 
for any stack that uses custom props with the same name to monitor various 
states of objects.  Jacqueline and Jacques (kind of musical, eh?), I 
experimented a little more and find that it is not limited to using y as the 
variable name or one-letter variable names in general.  I get the same problem 
when x is used for the custom prop on two different cards and when a two-letter 
name, xV, is used.  The problem is also there if you use an If control 
structure rather than Switch, and it is not limited to cards.  I set props for 
two buttons in the same way and lost the value of the same-named prop for the 
second button.  I haven't used Behaviours yet, but you can readily see how the 
problem could be pervasive there.

Jim, I appreciate the fix you suggest, but when you say long name, do you mean 
the long name of the card?  If so, then that does not work either.  In any 
case, a bug report is in order.

Hi René,

I know ! Nobody will have problems with multi-letter names : the 
CPropIWouldLikeToCallY or estimatedSlopeOfTheRegression  would work fine, but 
how boring to type compared to the usual a ! And I didn't see anywhere in the 
docs a caveat against the use of one letter names...

Re: Problem Calling Custom Card Props with the Same Name Using Switch

[René Micout]

Hello Jacques !
for the specific issue of temporary variables, I use the following names, which 
solves, I think, this type of problem: vtA, vtB, vtC, etc.. (pour variable 
tampon (ou temporaire) a, b, c, etc..)

Related remark: I remember I had sometime (not systematically) problems when 
giving one letter names to variables or parameters (e.g. a,b or x,y, which are 
so standart, in regression for example), but I was too lazy to digg deep in 
this question, it was simpler to change the name of the variable... but it IS 
some hidden pitfall somewhere.

Yes, I do it all the time.


What is important here is that both cards have a custom prop with the
same name, y, and that y has a different value for each (123 or ABC).
The button to show the values of the props also uses Switch.

on mouseUp
   put the short name of this card

This fails for me too, but only if I keep the property name you 
assigned. If I change the property to "cY" it works as expected. I'm not 
sure why, but I'd guess the engine is using "y" for something. Since I 
always preface my custom properties with "c", I haven't run into this 
before, but I think you should probably bug-report it. It's an odd one.

Re: Problem Calling Custom Card Props with the Same Name Using Switch

[DunbarX]

Confirmed. And it's odd, because the property value is there, at least 
right at the beginning:

on mouseUp
put ""
put return & "y" && the y of this card   && "z" && the z of this card 
after msg

--both properties are present at this stage

put the short name of this card
switch the short name of this card
   case "First Card"
  put the x of this card into x
  put the y of this card into y
  put return & "x" && x && "y" && y after msg
  break
   case "Second Card"
  put the y of this card into y
  put the z of this card into z
  put return & "y" && y && "z" && z after msg
  break
end switch
end mouseUp

The value is lost along the way, even though stepping through the script 
shows nothing untoward.

Problem Calling Custom Card Props with the Same Name Using Switch

[Gregory Lypny]

Hello everyone,

Can we assign the same name to custom props of two different objects, 
for example, the modificationDate of Card 1 and the modificationDate of Card 2?

I created a simple stack with two cards named First Card and Second 
Card, a common button that assigns custom props to each and another common 
button to show the values of each card's custom prop.  The handler in the 
button that sets the custom props uses Switch and it looks like this.

on mouseUp
   switch the short name of this card
  case "First Card"
 set the x of this card to 123
 set the y of this card to 456
 break
  case "Second Card"
 Set the y of this card to "ABC"
 set the z of this card to "DEF"
 break
   end switch
end mouseUp

What is important here is that both cards have a custom prop with the same 
name, y, and that y has a different value for each (123 or ABC).  The button to 
show the values of the props also uses Switch.

on mouseUp
   put the short name of this card
   switch the short name of this card
  case "First Card"
 put the x of this card into x
 put the y of this card into y
 put return & "x" && x && "y" && y after msg
 break
  case "Second Card"
 put the y of this card into y
     put the z of this card into z
 put return & "y" && y && "z" && z after msg
 break
   end switch
end mouseUp

If you click this button while on the first card, it correctly puts into the 
message box

First Card
x 123 y 456

But if you click it while on the second card, you get

Second Card
y  z DEF

where y is empty.  But, comment out the statement involving y in the first case 
of Switch and the second case will work correctly!

case "First Card"
 put the x of this card into x
     -- put the y of this card into y
 put return & "x" && x && "y" && y
     break

In other words, a statement that retrieves a custom prop in the case of Switch 
that should be by-passed is somehow affecting the retrieval and use of a custom 
prop with the same name in the case of Switch that is executed.  I hope someone 
can tell me that I've made a mistake because, otherwise, this could have 
serious consequences for stacks whose objects have custom props that monitor 
the state of an object and these props have the same names, e.g., the 
modificationDate of Card 1, the modificationDate of Card 2, etc.

Regards,

Gregory

Re: The Conference. RE switch

[stephen barncard]

I really like to use switch for any logic more than a single if-then-else.
Switch statements, due to their fall-through and default behaviors, can
handle more logic *conditions* than if-then
switch tInput
case 0
case 1
put tInput after tOut
case 2
   put tInput after tOut
case 3
put tInput after tOut
break
case 4
put tInput after tOut
case 5
put tInput after tOut
break
default
put tInput after tOut
end switch


tInput - tOut

0==>  123
1==>  123
2==>  23
3==>  3
4==>  45
5==>  5
6==>  6
7==>  7
...

when one gets used to the structure of a switch statement, it really looks
like it functions, and it's quite simple. Same thing with arrays.


All programming is simple, once one can break it down as smaller ideas put
together as a machine.

Re: Switch or If

[Kay C Lan]

You may wish to look back at these two threads, lots of benchmarking, sorry
I haven't figured out how to create links to old threads :-(

Subject: if statements vs case
Date: 27 feb 07
From: Hershel Fisch

Subject: switch case question
Date: 10/22/06
From: Mark Swindell

Basically what has been said so far is correct, timings are similar BUT Dar
Scott in the 2006 thread determined those cases (sorry for the pun) where
one will be faster than the other. I believe the general conclusion was, if
speed meant everything to you, you'd need to benchmark both.

Secondly, Randall Reetz wrote:

Whilst this is the 'normal' behaviour we think of, it is not the only
behaviour. If the 'break' keyword does not follow a 'case' structure, then
the statement flow does NOT exit the switch list. I use this all the time,
its a great feature of switch statements that allow the easy creating and
modification of OR conditions

switch tName
  case "Bob"
  case "Bill"
  case "Ben"
put "boy" into tGender
  break
  case "Sue"
  case "Sally"
  case "Sarah"
put "girl" into tGender
  break
  default
 answer "A Name I Don't Know"
end switch

I love switch for the benefits of script manageability. IMO they are very
easy to understand, very easy to figure out where to include extra case
structures if needed - something I always struggled with in large nested
if-then-else structures.

Another thing I like is they are fairly easy to manipulate if you need to
make some minor speed improvements. During development, simply by adding a
counting mechanism you can determine which cases are triggered most often
and therefore move those to the top of the structure.

Lastly, I've become fond of using the default structure as a logic error
catch all, as in the above example.

If it's yes/no, on/off, true/false, 1/0 then I use IF, but too often I
discover it's yes/no/maybe, on/off/sleep, true/false/no comment, 1/0/-1 so I
go with SWITCH.

Re: Switch or If

[Richmond Mathewson]

Hey, that was the only thing useful I learnt doing my "M.A" in IT at 
Abertay: what happens when you are

hit by a number 10 bus?

This is the reason my Granny always slipped on a clean pair before she 
went shopping. :)


Now, I am a bad programmer in several respects; and the worst is that I 
don't comment my way
through my code so when the next system development lifecycle comes 
round (Ha, Ha, Ha . . .
What SDLC in a one-room EFL school with 3 computers . . . you can see 
why matter attitude is a
bit slack). However, I for one, find reading through other people's code 
a lot easier to understand
with if . . . then loops rather than 'switch'; I never use the latter as 
on coming back to it later my

logic gets befuddled.

sincerely, Richmond Mathewson.

Wise words.  While I often adhere to the motto "A clock cycle saved

In many cases it should be possible to make whatever evaluation needs

can use whichever form best represents the logic involved while 
optimizing performance even more than using either within the loop.

Hi Camm,

Unless you're building something where the small difference in speed is 
absolutely critical, I would seek to answer a different question:  Which 
structure will be easier to understand and maintain in the future when I 
(or others) come back to it?

My 2 cents' worth -

This is a little test I did. I get about 35ms for 'switch', about 20ms 
for 'if'. As Jim said though, I suspect it'll vary according to the 
kind and complexity of conditions you're testing.



on mouseUp
   put the millisecs into tStart
   repeat 1
  put random(5) into tSw
  switchTest tSw
   end repeat
   put the millisecs - tStart into t1

   put the millisecs into tStart
   repeat 1
  put random(5) into tIf
  ifTest tIf
   end repeat
   put the millisecs - tStart into t2

   put t1 && t2
end mouseUp

-

on switchTest pSw
   switch pSw
  case 1

 break
  case 2

 break
  case 3

 break
  case 4

 break
  default

 break
   end switch
end switchTest

   if pIf = 1 then

   else if pIf = 2 then

   else if pIf = 3 then

   else if pIf = 4 then

end ifTest

RE: Switch or If

[Jim Bufalini]

Hi Camm,

I tested this many years ago and while it depended slightly on how the if/then 
was written, I was surprised that the if/then was faster, but only by a small 
amount. I can't speak for today and recent versions of Rev.

Aloha from Hawaii,

The Service USP Plus looks much easier to use (Rev support) and has onboard 
connectors for digital and analog I/O. It is very like the BeeHive gadget, and 
that was a wonderful product. You can do things right away.

This gadget looks like the right stuff. Works basically like the others, and 
Rev is the front end. Have to try one.

Thanks for the info.

Of course it was a compliment. We have to stick together, you know.

It is always possible to connect wires to a computer.The trick is to have fun 
doing so. The older gadgets had Applescript, Director, 4th Dimension and C 
support. But it was the HC XCMD's that everyone used. A Rev interface would be 
like old times.

Judy, you aren't really upset? :-(

Re: Import temperature and switch on/off the heater with Rev

[-= JB =-]

I really haven't done any usb stuff yet except configure the port.  I  
have done some testing
with an internal modem using the serial port.  The only thing I have  
done with usb is list
the devices.  It is possible the only way to access most usb devices  
is to write a driver for

Rev to access the port.

Makes you one of the oldsters, you know.

All three developers are out of the business.  There should be someone willing 
to take up the calling with Rev and USB, though. Someone smart and young. Free 
consulting to anyone who cares to. All you need is a PIC (programmable 
integrated circuit, $5) and the nerve.

[Thomas McGrath III]

Yes the HIGH SPEED serial adapter will work. I use it here all the  
time. The other serial adapters were not high speed and caused  
problems. I use the 19HS model that Stephen listed. I have also used  
straight USB devices that make use of the standard FTDIUSB Serial  
Drivers with great success.

Bob-

The Arduino works well with rev.

If you're using Windows and need to do some usb protocol
troubleshooting, there's a great tool available at

http://www.aggsoft.com/usb-port-monitor.htm

Unfortunately they don't have an osx version, and I haven't found
anything else that does this sort of packet-level analysis for the
mac.

Re: Import temperature and switch on/off the heater with Rev

[camm29]

Paolo ,

Should work ! 

If you do not have a RS232 Port then use a serial Port/Usb emulator driver.
If you have a RS232 Port then use a USB to RS232 cable convertor.

Rev will send / read from Serial Com Ports only , the above is the solution.

Rev 3.00 is better as you can use Com Ports > 9

Camm

Re: Import temperature and switch on/off the heater with Rev

[Thomas McGrath III]

Paolo, The Macintosh drivers for this device are the standard FTDIUSB  
Serial Drivers which emulate a serial device over USB so the good news  
is that you should be able to connect to the virtual port from  
Revolution on the mac. I am not familiar with the drivers being used  
for windows though.


The thing to look for is the serial emulation since Revolution can not  
handle the USB directly.


AH software has an X10 home automation controller in Revolution: Code  
for controlling the Firecracker CM-11 x10 controller


There are other serial examples as well.

Import temperature and switch on/off the heater with Rev

[paolo]

Dear friends, I had this crazy idea:

I would like to create a Rev application to control the temperature of  
my room. So, I need my application  to import the temperature from a  
thermometer and switch on/off the heater.


I found documentation for an affordable external device in internet : 
http://www.audon.co.uk/io8g.html

It says  "Compatible with Profilab DAQ Software. " and "Can Utilize a  
Simple Terminal Emulator to Control All Functions"


It says also: "Virtual COM port (VCP) drivers cause the USB device to  
appear as an additional COM port available to the PC.  Application  
software can access the USB device in the same way as it would access  
a standard COM port. "


Now, I have some questions:

Can we access the USB device using  a standard COM ports from  
Revolution?


Can we  have  Revolution to behave as a terminal Emulator to control  
all Functions?


To summarize, do you think I can menage to control this external  
device from Revolution?


Thanks a lot.

Re: Rev and joystick or switch

[Randall Lee Reetz]

Actually... I just wrote a test project... this code just takes  
mouseLoc and converts to vertical motion for a graphic



on mouseDown
put 0 into TopLim
put (the height of this window) into BotLim
put the loc of cd grc 1 into StrtLoc
put the clickLoc into CL
put (item 1 of StrtLoc)-(item 1 of CL) into HOffSet
put (item 2 of StrtLoc)-(item 2 of CL) into VOffSet
repeat while the mouse is down
put the mouseLoc into NL
if ((item 2 of StrtLoc)-((item 2 of CL)-(item 2 of NL))) > TopLim
then
if ((item 2 of StrtLoc)-((item 2 of CL)-(item 2 of NL))) < BotLim
then
set the loc of cd grc 1 to (item 1 of StrtLoc),((item 2 of StrtLoc)- 
((item 2 of CL)-(item 2 of NL)))

else
set the loc of cd grc 1 to (item 1 of StrtLoc),BotLim
end if
else
set the loc of cd grc 1 to (item 1 of StrtLoc),TopLim
end if
end repeat
end mouseDown

... and this code uses a vertical slider button that is set to act  
like a joy stick...



on mouseEnter
global BotLim,TopLim
put 0 into TopLim
put (the height of this window) into BotLim
set the minimumValue of me to (-1*((BotLim-TopLim)/10))
set the maximumValue of me to ((BotLim-TopLim)/10)
set the autoHilite of me to true
end mouseEnter

on mouseStillDown
global BotLim,TopLim
put ((the currentValue of me)*-1) into CV -- invert slider value
if ((item 2 of the loc of cd grc 1)+CV)≥ TopLim
then
if ((item 2 of the loc of cd grc 1)+ CV)≤(the height of this window)
then
set the loc of cd grc 1 to (item 1 of the loc of cd grc 1),((item 2  
of the loc of cd grc 1)+CV)

else
set the loc of cd grc 1 to (item 1 of the loc of cd grc 1),BotLim --  
bottom limit

end if
else
set the loc of cd grc 1 to (item 1 of the loc of cd grc 1),TopLim --  
top limit

end if
end mouseStillDown

on mouseUp
set the currentValue of me to 0 -- reset slider to center

Fewer buttons the better, and no flash rumbling or stuff like that.

Any suggestions for simple and preferably cheap hardware that folks

RE: Rev and joystick or switch

[Randall Reetz]

With usboverdrive (google it, download it, install it) you can send keystrokes 
(arrow keys, etc) events from a joystick or game controller.  But maybe there 
is a rev native solution???

If I understand your situation it is like this:

If you select the 1st choice in your 'Master' option menu you show 'slave'
option menus 1, 2 and 3.
If you select the 2nd choice in your 'Master' option menu you show 'slave'
option menu a,b, and c.
if you select the 3rd choice in your 'Master' option menu you show 'slave'
option menu  1,b,3,d
...

For the scripts in your 'slave' option menus you want different actions
based on not only what selection is made, but what selection was made with
the 'Master' option menu.

If I've got that correct, and assuming that your 'slave' buttons have many
options so you want to keep the switch statement compact, then the script in
your 'slave' buttons could look something like this:

on menuPick pChosen
  switch pChosen
case "1 Choice"
   --avoid statements here to keep switch statement compact
  handler1Choice
break
 case "2 Choice"
   handler2Choice
break
...
...
 case "987 Choice"
   handler987Choice
 break
--always good to include in the development phase to hi-light omissions.
default
  answer "A case I've not accounted for." titled "Case Omission"
  --check the variable watcher - pChosen
  breakpoint
  end switch
end menuPick

--the following will also be in the button script

on handler1Choice
  switch the label of btn "Master"
case "Choice 1"
   --statements here
   --use a handler if too many statements
 break
case "Choice 2"
--statements or handler
 break
 ...
 ...
case "Choice 99"
   --statements or handler
break
--always good to include in the development phase to hi-light omissions.
default
  answer "A case I've not accounted for." titled "Case Omission"
  --check the label of btn 'Master'
  breakpoint
  end switch
end handler1Choice

on handler2Choice
  --switch structure again
end handler2Choice

as many as required.

Although nested switch statements are possible, and are easy enough to
follow if you only have a small matrix of options to cover, once the options
start to multiply it's very easy to created a very complex structure that is
hard to follow and easy to miss options - which is why I like to use the
default statement to catch omissions.

You can certainly nest switch statements without problem - you'll end

Re: Exit Switch or break switch question

Len,

I just checked and unless I missed something there is no choice for  
multi-line selection in the ComboBox.

Hi Len,

Multiple exit points seems like a good point for clarity unless maybe
the switch is very very long then you would know if one was found it
would be the absolute end of the script instead of the possibility of
it finding another match as well later on in the script.

However, with that said, this is a combo box and I would think only
one choice can match so the break seems to be my answer for both
clarity (smaller script) and few keystrokes and because no other
matches are possible anyway.

Thanks,

Tom McGrath

If I want to leave a switch statement after successfully matching a
case is it better to break and rund to the end without a default
statement or to exit the switch from that case?

ComboBox

on menuPick pChosen
   switch pChosen
   case "Home"
   -- code goes here
   exit switch
case "Work"
   -- code goes here
   exit switch
   end switch
end menuPick

OR

on menuPick pChosen
   switch pChosen
   case "Home"
   -- code goes here
   break
   case "Work"
   -- code goes here
   break
   end switch
end menuPick

Re: Exit Switch or break switch question

[Eric Chatonet]

Hi Tom,

Break skips the rest of the current switch structure and goes to the  
statement following the end switch.

Only four chars to write ;-)

Le 20 mars 08 à 16:06, Thomas McGrath III a écrit :

on menuPick pChosen
switch pChosen
case "Home"
-- code goes here
    exit switch
 case "Work"
-- code goes here
    exit switch
end switch
end menuPick

OR

on menuPick pChosen
switch pChosen
case "Home"
-- code goes here
break
case "Work"
-- code goes here
break
end switch
end menuPick

Exit Switch or break switch question

[Thomas McGrath III]

If I want to leave a switch statement after successfully matching a  
case is it better to break and rund to the end without a default  
statement or to exit the switch from that case?


ComboBox

on menuPick pChosen
switch pChosen
case "Home"
-- code goes here
    exit switch
 case "Work"
-- code goes here
    exit switch
end switch
end menuPick

OR

on menuPick pChosen
switch pChosen
case "Home"
-- code goes here
break
case "Work"
-- code goes here
break
end switch
end menuPick

Thank you,

Tom McGrath

Much clearer - thanks everyone - I think the documentation should be a
little clearer with this?

So I had a go - which proved pretty difficult - I don't envy anyone trying
to do technical documentation. Here is the best I can do for now. I added a
few examples and i think the hypertext links to definitions explaining the
terms helps - still could do with some improvement:

Re: Switch Statement

[Rob Cozens]

Hi David,


I use the switch statement a lot - but only for basic "case" tests and
have not been able to get:

   "If the caseValue is equal to the switchExpression, or the
caseCondition evaluates to true"


Don't forget that switch logic falls through from case to case if 
there is no "break" statement; so


   [put whatEver into switchExpression]
   switch
case caseValue = switchExpression
case caseCondition = true
[case logic]
break
default
    [optional default logic]
end switch


working. Here is an example that I just changed from "if then else" -
whats wrong with it:


You are combining two forms of the switch statement.  By designating 
mainChoice as the switch, the value of each case is compared to 
nainChoice.  Try:


   switch mainChoice
case "Go to script object"
break
case empty
case "This menu script"
put the long id of me into scriptObject
break
case "Library 1"
case "Library 2"
...
case "Library n"
put the name of stack secondChoice into scriptObject
break
case "Unsorted"
edit the script of stack "libOPN_Unsorted"
break
default
breakpoint
end switch

This assumes a finite number of libraries with known names.

Re: Switch Statement

[Eric Chatonet]

Hi David,

If you specify a variable just after the switch statement, each case  
value refers to this variable.

So, in your case, try:

switch -- note there is nothing more here ;-)
case mainChoice = "Go to script object"
break
case (mainChoice is empty or mainChoice is "This menu script")
put the long id of me into scriptObject
break
case (word 1 of mainChoice is "Library")
put the name of stack secondChoice into scriptObject
break
case mainChoice = "Unsorted"
edit the script of stack "libOPN_Unsorted"
break
    default
breakpoint
end switch

Hope this helps :-)

My understanding is that:

  (word 1 of mainChoice is "Library")

is an expression which evaluated to true or false - but steeping
through i the debugger when mainChoice is "Library" the case statement
is not triggered and instead the default case statement is activated?

Hi,

As a test, do this:


set the cpTest of this stack to empty
switch (tTarget)

case "btnBildKopieren"
put the cpTest of this stack into myTemp
put tTarget & cr after myTemp
set the cpTest of this stack to myTemp
break

-- copy the above code for each "case".

end switch

put the cpTest of this stack into myTemp

This should tell you if the case statements are running into each other.

Hi Ken,
I added the Ifs after the problem occured just for my test scenario. The
problem was there before I added the Ifs and is still there with the Ifs and
cpTest = false. Perhaps I am working completely at the wrong side of the
problem, I think I have to look for a redesign.

I haven't run into this before, but I *have* run into situations where 
the "if... then..." structure without an "end if" gave me unexpected 
results (but it wasn't on a specific platform). Can you try 
restructuring your "if"s so that they go like this:

  if the cpTest of this stack is true then
answer "Test1"
  end if

It may not help, but other than that I can't see anything that might be 
a problem with the code you posted.

switch - case works different on Win-Mac !?

[Tiemo Hollmann TB]

Hello all,

I am struggeling with a mysterious problem, where a mac standalone calls
different handlers as a win standalone in a switch structure, build on Win
with 2.8.1. I have one big switch structure on stack level to handle all
button ups. It looks like this, nothing sophisticated:

 

switch (tTarget)

-- some more cases   

case "btnBildKopieren"

if the cpTest of this stack is true then answer "Test 1"

-- calling some handlers

break

case "btnBildSpeichern"

if the cpTest of this stack is true then answer "Test 2"

 -- calling some handlers

break

case "btnBildEinfügen"

if the cpTest of this stack is true then answer "Test 3"

-- calling some handlers

break

-- some more cases

end switch

 

This worked perfect on Win, but now testing on Mac more than one case
structure is executed (at least it seems so, because the result is as if
so), though I have a break in each case. Because I don’t have a Mac for
testing, I integrated the above test answers to see which way the handler
goes. So I set a custom property “cpTest” to true to get the answers to
follow the execution. Now the funny thing happens. When activating the test
answers, everything works OK on Mac as on Win. Once I set the cpTest
property to false and I don’t get the answer dialogs, the program brings the
unwanted results again and runs probably into different case structures. I
changed already the sequence of case structures, without result. I don’t
know, where to look for any more and can’t debug it on my Win machine,
because on win I can’t reproduce this error.

Has anyone seen something like this before and has any idea where to look
for?

Thanks for any hint

[OT] The switch of perception - some immediate patches

[Bob Warren]

1. I should have said that care in both reading AND WRITING is necessary.

2. For an "ugly old woman" interpretation of what I said, the whole 
register of what I was saying needs to be changed: i.e. what is really a 
proposal for the future needs to be misinterpreted as a description of 
the current state of affairs. It may or may not be, but that is not what 
I intended to say in my proposal.

[OT] The switch of perception

[Bob Warren]

Some of you may have had the interest to read an article I wrote which 
can be found at: http://www.bobsite.org/brazil/ .


Early in the article, there is a classical design from Gestalt 
Psychology (the psychology of perception) that can be seen either as a 
nice young woman or as an ugly old woman. One thing I did not attempt to 
discuss in the article was the part that motivation can sometimes play 
in perception. That is perhaps a pity, because it is sometimes a highly 
relevant factor. Where language is involved, care in reading (or the 
lack of it) can also play a part.


I've been racking my brains to try and discover how it was a thread I 
participated in recently ("Open Source (was Don't you just wish Rev 
would do this?)") changed from a happy problem-solving process into a 
nightmare, demonstrating a problem rather than solving one. I now know why.


In my first post about the subject, I described a hypothetical 
arrangement. Instead of using "would" throughout (a linguistic option), 
I used the present tense: e.g. According to the proposed arrangement, "I 
do this" and "You do that".  Of course, had I realized at the time that 
this might lead to any kind of confusion, I would have peppered my 
proposal with lots more "woulds".


Here is an elaboration of what I intended to say by the two items given 
early in my first post:


1) I propose that Rev should produce IDE upgrades from now onwards that 
would concentrate on the provision of new features. I propose a strictly 
regular cycle for their release (perhaps slightly different to the 
current one). These "feature releases" represent the product that we, 
the users, should expect to pay for, and to pay for at least as well as 
the product merits.


2) I propose that bugfixing should be a continuous process between 
feature releases, aimed at correcting the current release as necessary. 
There would of course be no additional charge for it.


These are the actual words I used:

1. RR should provide feature releases on a regular basis. We pay for them.
2. We do not pay for bugfixes. The manufacturer is just putting right 
what he has done wrong.


Now here's an "ugly old woman" interpretation:

1. RR do not provide feature releases on a regular basis as they should. 
We pay for them, so Rev is doing the dirty on us by not coughing them up 
according to their obligation.


2. Rev are even making us pay for bugfixes! Well, we ain't gonna do it.

See what I mean?

Of course, after an initial "ugly old woman" interpretation, a 
psychological set has been established and everything that I say 
afterwards gets totally ignored, even if it doesn't quite add up 
logically! This "set" perception is so strong that it wouldn't surprise 
me if some people thought I was making excuses by the explanation I have 
just given!


Sorry, I realize this is not the place to discuss (even relevant) 
psychology really, but I was disappointed by what happened.

Re: switch case question

Excellent Detective work Dar. It also reinforces a habit I'm trying to
develop when writing switch statements, and that is to always use the
default as a catch for cases I haven't considered:

switch L
 case (5)
handler1
 break
 case (5.0)
handler2
  break
 case ("5")
handler3
 break
 case ("5"&"."&"0")
handler4
 break
 default
   answer "Switch statement error" & return &
  "Handler: myHandler" & return &
  "Paramater L: " & L
  exitGracefully
end switch

Obviously, from what you're saying, handler3/4 would never run, but
more importantly, if 5. (decimal point byt no zero) got into L, I
should get immediate feedback that I haven't correctly taken it into
account in my switch structure.

I've wasted a lot of time stepping through scripts that don't do what
they're suppose to do and often it is because I've added a feature to
and old stack and don't realise that this new feature now puts new
values into properties that get checked by some buried switch
structure which completely ignores it because it was never part of the
original cases considered. Using default as a catch nails it
instantly.

Hope that helps someone:-)
