Re: save data in custom properties in a stack- or a text file?

Unfortunately (and this would be a nice to have), custom properties

But it's still possible to encrypt custom props and protect by  
password the code able to decipher them :-)

Re: save data in custom properties in a stack- or a text file?

[Josh Mellicker]

Hi, and thanks for all your responses.




entering/reading data manually: text file way easier


What is "manually" in this context?  What other processes in the  
workflow require "manual" editing?


Basically I was saying typing stuff in a text file is easier than  
altering custom properties with a property editor and the message  
box; (mostly during development)



What if your data was this:

Revolution Coders
2.0

Richard,http://www.fourthworld.com/,http://www.fourthworld.com/rev/
Jacqueline,http://www.hyperactivesw.com,http://www.hyperactivesw.com/ 
Resources.html
Andre,http://andregarzia.com/,http://www.andregarzia.com/RevOnRockets/ 
index.html




Would you tend to store the above in a text file? Or custom props?



On a side note, this is how I'm encrypting a local text file with  
registration info:


function lbencrypt tData
encrypt tData using "blowfish" with password productInfo 
("regFilePassword")

put the base64encode of it into it
return it
end lbencrypt

Re: mercy...Control-A and text selection revisited

Hi Mark,

After a user enters cursor in a fld (its traversalOn property is  
true), I want control-A to select the text of that fld.  How do I  
do it?


Sarah answered yet in the case you have a menu bar but may be you  
have not :-)

A controlKeyDown handler will work if you put it in the card's script:

on controlKeyDown pKey
  switch pKey
  case "A"
if the selectedfield <> empty then select text of the selectedfield
break
  default
pass controlKeyDown
  end switch
end controlKeyDown

In addition, if you want to have a button to select the text of the  
field also, just set the traversalOn of the button to false (it will  
not become the focused object when clicked) and in its script, refer  
to the above handler:


on mouseUp
  controlKeyDown "A" -- C
end mouseUp

Re: Find Command

Why?


Line 2 above will put a "return" character (numToChar(10) at the end  
of wordToFind (except when clicking the last line). The "find string"  
method doesn't allow return characters. Also, the find command  
searches forwards from the previous find, so subsequent clicks may  
not give what you want.


A crude approach:

on mouseUp

  select the clickline
  put the selectedtext into wordToFind
  if charToNum(char -1 of wordToFind) = 10 then
delete char -1 of wordToFind
  end if
  find empty ## clear previous finds
  find string wordToFind in field 1
  put wordToFind & the result

Re: [slightly [OT]] A little Help removing Galaxy

[william humphrey]

I didn't go to the galaxy forum because of laziness born of frustration. I
think that the "command -" and "cmd shift" are built into revolution and
you're right "cmd shift" is sort of broken so it explains why I couldn't get
it to work when random trying everything. Galaxy has a built in commenting
system that is different because I was able to access it once and I will
keep trying to find it.
 Thanks for answering and when I have some time I will spend it on the
Galaxy forum because I think it would be really cool if they would make a
one or two page PDF with all the cmd key "thingys" and short cuts so that
other users would have a happier experience.

It may be that I am just in the dark ages and pine for the time in the
distance past when software came with manuals (or you could buy books). I
still love my old Hypercard 2.0 book by Danny Goodman. It was the first
software manual I ever enjoyed reading.

data stream processing

[viktoras didziulis]

 Hi.

I have a console application that constantly spews out numbers at a rate 
of 3 numbers per second. The task is to read the number and display it 
in a field, then as soon as the next number arrives it should replace 
the field's contents with new number visualise it graphicaly and so on 
ad infinitum in realtime...
I can't figure it out - Revolution expects the data stream coming from 
outside will end at some point and therefore waits. But the process is 
in fact never ending. Is there a way to handle this kind of constant 
data stream in Revolution ?


Best wishes

True. But I was thinking about the file as it is stored on the server. 
If someone were to access the file and didn't have Rev to open it, they 
would have to look at it in a text editor or similar. In that case, none 
of the custom properties are readable if it is a password-protected 
stack. It's a crude type of protection, I admit, but it discourages 
casual attempts.

Vista dilemma

[Chris Sheffield]

I'm wondering if anyone can help with this.

I've got a standalone that, by default, is installed to the Program  
Files directory. At one point, it performs a check to see if the  
currently logged in user can write to that directory. Right now I  
just have it attempt to write to a file and then delete the file.  
Under Win 2000/XP this seems to work great, but under Vista the darn  
VirtualStore "feature" is fouling things up.


So, question number one. Is there some way to tell my standalone, or  
the Vista OS, that I really and truly want my check to be performed  
on the Program Files directly, and not have things redirected to the  
VirtualStore?


Question number two. If the above is not possible, is there some way  
to determine (via shell command perhaps) what type of user is  
currently logged in to the computer (i.e. admin, standard, etc.)? And  
if so, would this command be available to by any user to run from the  
shell? This would be a better way to go all around if it's possible.


Thanks,
Chris

Re: data stream processing

[Phil Davis]

Hi Viktoras,

Can the data stream come to the Rev app through a network port? If so, the easy 
solution would be to do something like this:


on openStack
  accept datagram connections on port xx \
  with message "handleData"
end openStack


on handleData pIPAddress, pData
  -- handle the data
end handleData


Then each time data arrives it will be handled, no matter how often or how 
infrequent.



Just a thought...

Re: Vista dilemma

[Scott Kane]

- Original Message - 

So, question number one. Is there some way to tell my standalone, or   the 
Vista OS, that I really and truly want my check to be performed  on the 
Program Files directly, and not have things redirected to the 
VirtualStore?


First - check out Version in the Help doc's.  Vista is Version 6 I believe 
from memory.


Second - Microsoft have stated that Virtualization is not guaranteed to be 
in future flavours of the OS.  The whole point of the tool is so that 
existing app's don't break - backwards compatibility.  However the logical 
thing to do is to change the location of the data using code - consider My 
Documents etc.  Otherwise Virtualization is going to bite you one day when 
you least expect it (service pack update for example).


Question number two. If the above is not possible, is there some way  to 
determine (via shell command perhaps) what type of user is  currently 
logged in to the computer (i.e. admin, standard, etc.)? And  if so, would 
this command be available to by any user to run from the  shell? This 
would be a better way to go all around if it's possible.


Admin is spurious under Vista.  You may be the Admin but you are not 
considered to be the "Full Admin".  The OS performs that role.  It is 
possible to elevate an application to Admin level (executable called 
Update.exe or Setup.exe gets this privelidge).  However, again, it's much 
better to code so that data is in My Documents or App Data.  In existing 
installations move the data as part of an update process.

Would you tend to store the above in a text file? Or custom props?


For myself it would depend on a number of other factors:

- Will I ever need to store other lists related to this one?
- Will the system ever benefit from adding metadata to the data storage?
- How quickly will I need to access elements?
- Are such accesses more often sequential batches or individual items?


If I'm reading your posts correctly it sounds to my ear like you've 
already decided.  If it works, why change?

The only way to prevent virtualizing AFAIK is to turn off User Account 
Control. My understanding is that even if you're logged in as Admin, if 
you have UAC on, it will still virtualize because it is the 
*application*, not the user, that controls whether it can write to 
"protected" locations. And in order to do *that*, you'd have to find 
some way to make your application act at an elevated level. 

Of course in this case, you don't want to always write the file - you 
just want to know if the folder is writeable, which under Vista means 
knowing whether UAC is on or not.Actually there are three states 
(AFAICT):

1) UAC off: Completely disables UAC, no virtualization occurs.
2) UAC on ("quiet mode"): This will enable UAC, but suppress the 
elevation prompts for members of the Adminstrators group.
3) UAC on: Enables UAC, shows all elevation prompts regardless of group.

Unfortunately at the moment there are is some people who have done this 
with C++ and C#, but I don't think we have a command-line or other 
Rev-accessible way to determine this state. My recommendation would be 
to find some other place to write your files (I know, it's a pain, but 
unless there's someone out there who has a way to detect UAC state or 
wants to create a Rev external, I don't really see how you can know if 
your data was virtualilzed).

Any chance you can have people turn UAC off? When they do that they are 
back at the "XP" level of security (IIRC).

Re: Shy Images

[Len Morgan]

Thanks for the help Ken and Dave.  Ken's routine worked almost untouched 
(just a little renaming of the variables).


I'm having a few problems where the "mouseRelease" message is getting 
sent (it drops the picture where the mouse button was let go) but then 
it still seems to think I'm holding down the button and I've still got 
an image that's getting dragged around.  This leaves images laying 
around all over the screen.


Since the code Ken wrote has a "delete sTarget" (which is the image that 
I'm dragging around) I don't know why I still have an image.  I don't 
need this dragged image (all I really want to know at the end of the day 
is the group I started dragging from and the group I dragged it to.  
After that, I'll use script to do the behind curtain stuff that will 
delete the picture in the original group and set the filename on the new 
group.


Ken's code seemed perfect for this since it copies the original image 
and drags around a copy which gets deleted when I let go of the mouse. 
At least that's the theory.

Re: mercy...Control-A and text selection revisited

[Mark E. Powell]

Hello Eric

It does not work for me.  For testing, I created a simple stack with one field 
and the script you suggested in the card script:

www.aboutmyfiles.com/controlKeyDownTest.rev

With the cursor in the field, control-A does nothing.  If I choose Select All 
from the Rev IDE Edit menu, same thing (i.e. nothing).  Does it work for you?

If yes, then it has to be an effect of the loss-of-focus bug that is in 2.8.0, 
which is what I am running.

Please let me know when you have a moment.

Thanks!

Checkbox maker

[Jim Lambert]

I've uploaded

EZ Checkbox Family

to RevOnline under Categories>Utilities or Users>JimL.

It contains a Checkbox Family control that  lets you create groups of 
checkboxes with a just single click and get the selected items with one 
line of code. There are also a few commands to interact with the 
checkbox control programmatically.


This is somewhat related to the recent thread: "create a html list, but 
with a char where the image shall be".


Hope you find this useful.

You should probably add a mouseUp handler too that is identical to  
the mouseRelease handler. This will catch cases where you release the  
mouse while it is still over the original target.


Not sure if that is the cause of your current problem, but worth trying.

Revolution has some commands for managing resources. I wrote a utility
stack for doing this which you are welcome to try
. It's been a
while since I looked at it, so I don't know if there have been any
changes in recent version of Rev that might have affected it, but it
should give you some ideas anyway.

Dave was right, line 2 had a return in it. line 5 did not.

I discovered this 20 minutes after I went to bed, got up and lo and  
behold

it now works.

Another difference between HC and RM.

Many thanks.

Bob

Friends, I have recently upgraded from HyperCard to Revolution Media.

I am recreating some hypercard stacks.

I am having a problem with "find"

The handler below:

   on mouseUp
1 select the clickline
2 put the selectedtext into wordToFind
3 find string wordToFind in field "TestFld2"
4 put wordToFind & the result
5 find string "Cafe (das)" in field "TestFld2"
  end mouseUp

line 5 works as expected.
line 3 returns "Not Found"

Why?

Re: save data in custom properties in a stack- or a text file?

[Stephen Barncard]

Again I say it's how you or your user use the data, and their skill 
in maintaining it without errors.
If you find yourself complaining about editing custom properties in 
the inspector, then take an hour and write a property editor that 
saves properties instead of saving as a text file. This allows you to 
control and contain the data easier.   If your users make errors 
editing text files (extra spaces, etc) then put the data entry under 
your control - verify each item before entry.




Hi, and thanks for all your responses.




entering/reading data manually: text file way easier


What is "manually" in this context?  What other processes in the 
workflow require "manual" editing?


Basically I was saying typing stuff in a text file is easier than 
altering custom properties with a property editor and the message 
box; (mostly during development)



What if your data was this:

Revolution Coders
2.0

Richard,http://www.fourthworld.com/,http://www.fourthworld.com/rev/
Jacqueline,http://www.hyperactivesw.com,http://www.hyperactivesw.com/Resources.html
Andre,http://andregarzia.com/,http://www.andregarzia.com/RevOnRockets/index.html



Would you tend to store the above in a text file? Or custom props?

Re: data stream processing

[Pierre Sahores]

Hi,

In such kind of tasks, an UDP connection would probably be the  
simplest way to have Rev getting and displaying your outside incoming  
datas.

 Hi.

I have a console application that constantly spews out numbers at a  
rate of 3 numbers per second. The task is to read the number and  
display it in a field, then as soon as the next number arrives it  
should replace the field's contents with new number visualise it  
graphicaly and so on ad infinitum in realtime...
I can't figure it out - Revolution expects the data stream coming  
from outside will end at some point and therefore waits. But the  
process is in fact never ending. Is there a way to handle this kind  
of constant data stream in Revolution ?


Best wishes
Viktoras
