Cryptograhy

[JB]

I was testing base64 and the Pack function
written by Richard Gaskin and after packing
and unpacking the data appears the same
but does not properly write to a file.

For instance I have a image that I read as a binary
and put the info in a field.  Then I base64Encode it
and put the date into a field.  I am able to take the
encoded data and use base64Decode which will
decode it to its original form and I am able to write
that data to a file and I have the original image.

When I use the Pack function it does the same thing
but adds a password if you want it and encrypts it.

After I unPack the date the date looks the same as
the original but when I write the date to a file I end
up with a corrupted file and cannot view the image.

Does anyone know why the file gets corrupted?  I
have the same problem when I use base64Encode
and convert the encoded ascii data to hex and back
to ascii then decode it.  The data looks the same but
I end up with a corrupted file.

Re: Cryptograhy

[JB]

Thanks for the quick response and info.

I am using this code to write the file

open file filePath for binary write
put fld id 1004 into theData
write theData to file filePath

and it writes the data properly if all
I do is base64encode/decode.  When
the encoded data is altered and then
put back to what appears to be the
same and decoded it ends up corrupted
after decoding it.

I can take a Hex file and convert it to
ascii or binary and back again and it
will write the image properly.  But when
I convert the ascii from base64encode
it ends up corrupted.  I have used regex
to remove NULLS and CRLF but that does
not solve the problem.

I can send you the code but the code that I
am testing at the moment is fwPack.  Are
you able to use the code to pack and unpack
a image and write it to disk?

thanks again,

Re: Cryptograhy

[JB]

I just did a compare of both files and
there was nothing different at all.

Then your answer included a better
file open and write which included
url and special folder path.

Thank you very much for the help
Not to be mean but my initials are actually
JB not BJ.  I know I made a lot of mistakes
with the word data being date.

Thanks again for the help I appracieat if
very much.

Re: Cryptograhy

Not a problem.  I can’t even begin to tell
you how much this has helped me.  I am
working on a project that I wanted to use
base64 on instead of accessing a line tool
command and as you can see I was having
problems.  Your code fixed it and now I do
not need to use the command line.

ListMagic

[JB]

I have ListMagic which I purchased many
years ago and now for some reason it is
a trial version.

It was registered and when I asked LiveCode
they said they are not able to retrieve lost keys.

I finally found the key and now I need to know
how to properly register it.

Will someone please tell me where to paste the
registration key into ListMagic.

thank you,
John Balgenorth

Re: ListMagic

[JB]

Hi Matthias,

Thanks for the help.

I finally found you can enter the registration key
by clicking on the Presentation tab in ListMagic
and scrolling to the bottom of the page where
there is a button to enter it.

After entering the key it registered for me without
any problems.

Your fix is still important to know since I registered
it many years ago and I probably have the folder
already.  You would think the Installation tab would
be a good place to find information related to the
installation of the full version.

thank you,
John Balgenorth

Re: ListMagic

[JB]

Hi William,

Thank you for the good advice and info.

I think you have learned the hard way and
will consider it very much because I have
learned the hard way too.

I do like ListMagic and might still use it now
that I finally registered it again.

But I am going to try to use mostly LiveCode
and the tools they provide since they are more
likely to make sure it works.

As for them not being able to retrieve lost keys it
is because they did not sell ListMagic and do not
control their products.

All of these problems are actually a plus for using
LiveCode tools to do the job.

Thank you,
John Balgenorth

Standard Library

[JB]

Revolution Standard Library was put together by
Richard Gaskin and Ken Ray and provides a lot
of useful handlers.

Is the code allowed to be used in a commercial
program royalty free and if so what would be the
proper information to list in the product showing
it is being used and plus the proper credits.

Has the library been updated recently and if so
where can it be downloaded?

mean using small parts of it which would
be what appears it is made for.

Re: Standard Library

[JB]

Hi Richard,

Thanks for the fast reply.

I was searching for a way to get file info so I could
display things like the size and creation date and
after using google I saw a post that you answered
and you provided the handler to do it.  Eventually
I somehow ended up finding a download but I do
not remember where.  I do know that I downloade
it many years ago so I already had it.

As I mentioned the part I was interested in mainly
was file info so I did not need to use the default
folder to get the info.

Concerning the framework or handlers I definitely
would prefer to use handlers and then I can use
what I want and not use globals.

It seems to me a lot of people probably will eventually
find a need for one or more of these handlers and the
more made available the better off the community will
be.

My use will be simple at this time and will not really be
a modification.  I am going to be using ListMagic to put
the name of a file the user will enter and I wanted to
have the file listed in the same way the finder shows it.

One of the things I am interested in seeing more handlers
and examples is regex.  It seems to be a very powerful
tool with very few LiveCode examples.

Another good idea would be the command line examples.
I was able to get a command line to do what I wanted but
this took many hours and needed s special way of writing
it.  Phil Davis has some examples that show how to access
the manual in the terminal but those examples do not work
with using the command line that I wanted which was xxd.

A question about using command lines is can they be used
in a commercial product and is there any possible reason a
command line that is being used in LiveCode today won’t be
able to be used for some reason or another in the future.  If
so this can cause a complete failure of a good program and
is risky business to say the least.  As for xxd the manual list
the person who wrote it and he states anyone can use it free
of charge but if you make money he would like you to share.
I do not think he wants a royalty on a continuous basis but he
would appreciate a little bit of money.

thanks again,
John Balgenorth

Thanks for the info about regex.  I bookmarked
the website and will be using your advice.  I am
pretty new to regex and even though I’ve spent
a lot of time researching it you have helped me
tremendously.

externalPackages

[JB]

I built a external using the external examples
and have created the stack and installed the
external.  Everything works and now I want to
see the externalPackages of my stack.

I created a button and put the following script into it.

on mouseUp
put the externalPackages of stack "rnahelloTest" into fld id 1004
end mouseUp

What happens is it sets my field to empty.
I was thinking that since I have installed
the external properly and the stack is able
to use it properly it would list my external.

How do I use the externalPackages?

Getting File Type

[JB]

The Standard library would not give me the
file type when I tried it so here is a handler
I wrote that will give the file type.

on mouseUp
   answer files "Select the file you want the type info"
   put the longFilePath of line 1 of it into filePath
   put number of chars in filePath into n
   put "false" into geType
   put empty into theType
   repeat for n times
  if geType = "false" then put char n of filePath before theType
  put n - 1 into n
  if char n of filePath = "." then put "true" into gType
  if gType = "true" then exit repeat
   end repeat
   --put theType into fld id 1098
   ask "File Type" with theType
end mouseUp

I am sure someone can write it better but it works.

Re: getting File Name

Hi Scott,

I am using a Mac and it allows a / in the

you simply get the last item it would not
give you the full name.

Installing Externals

[JB]

Trevor at Blue Mango wrote a excellent article
about installing externals.  In it he said

Open the Externals.txt file (1), creating it if necessary.
You need to add one line to this file that tells Revolution
about your external. The line contains 2 items. The 1st
item is the name of your external as it appears in the
externalPackages property (2). In this example I'm using
the EnhancedQT external so that name is EnhancedQT.
The 2nd item is the name of the external file 

The problem I am having is with the name of the first item
which is the name of the external as it appears in the
externalPackages property.

In the lesson that name is EnhancedQT.  But the name of
the second item is the file name which in this case is
EnhancedQT.Bundle.

So both items togethor make the single line to add which is

EnhancedQT,EnhancedQT.Bundle.

That is pretty easy but the problem is the first item is not
always named the same as the file name.  It could have
been anything other than EnhancedQT.  If it was always
the name of the file name without the .Bundle this would
solve all the problems.

How do you get the name of the first item if you do not
know what it is.  You could try the name of the file and
not include the .Bundle and in this case you would get
lucky and it would work.

Re: Execution of a "long" script

[JB]

What if you are dong large scripts that tale many hours and the
user decodes to do things that will slow it down.  Whwn you are
using Time Machine you can trust that it will keep working and
not cause a crash.  At least I have never had it crash.

Can you trust this large script will not crash or should you inform
the user the chances of a crash will increase if they use other
memory intensive applications.  Is there a way to prevent it?

Re: Execution of a "long" script

[JB]

Why do you waste your time
attacking me?

You have no clue what I am even
writing or if my program was going
to fall in the category of using long
scripts.

My question for you since you will be
a user is when are you going to pay?
You won’t be getting a complimentary

Re: Execution of a "long" script

[JB]

Thanks Richard!

I was concerned about it after the question was brought up
because there is a chance someone will select a lot of files
to process and I have never tested LiveCode with scripts
that take a long time.

I was glad the question was asked because it made me take
into consideration of a possible crash from any reason and I
will be sure to keep track of the work done so it can start up
where it crashed and not worry about repeating the work.

Once again you have provided me very good information and
the comfort in knowing it has been tested for extremely long
tasks.  Knowing that means a lot to me.

Re: Standard Library

[JB]

That is nice to know!

I was thinking I would speed up the
longer text processing.  You just did
me a favor and save me a lot of time
plus made it easier and faster by not
using regex for text processing.

I still appreciate the info others gave
because I know I will use regex from
time to time.

Re: Standard Library

[JB]

I was interested in using a if then replace combination
but it seems it might be better done in LiveCode using
repeat for each.  If the speed is not considerably faster
with regex it is not worth the trouble.  The ability to read
my code like I am used to is more important than a small
increase in speed.

Re: externalPackages

Hi Richard,

Since you come from a SuperCard background could
you answer a question for me?

I am a registered owner of SuperCard 4.6 and SuperEdit 4.6.
The Xtend section allows you to export externals.  I contacted
SuperCard Support and they said I could use the SuperCard
externals in other programs that use externals as long as I
abide by the EULA.  That is not a problem.

I exported a external and tried to use it in Revolution and could
not get it to work.  The next thing I was going to try is to make a
empty external for LiveCode naming it the same as the external
I want to use and from SuperCard install it into the resource by
changing the type from .bundle to .txt and then change the type
back to .bundle.  I have done that without making the empty
external so I have not actually tried it yet.  Is that the proper
way to install a SuperCard external in Rev or is it not possible
at all to use them in Rev?

thanks,
John Balgenorth

Re: externalPackages

[JB]

Thanks for the info.

I don’t really need any of them I was just trying
to use them if it was possible.  Your information
shows it is not possible and therefore I won’t
waste my time on it.

I am surprised that as long as LiveCode has been
around there are not more externals available.  If
you have developed externals for LiveCode why
not sell them like was done for HyperCard?  That
would be better than the Standard Library at least
for your pocket book and might encourage others
to earn a few dollars too.  It would be kind of like
fast food marketing.  Usually when you find one
fast food place others are in the general area and
might even be across the street or next door.  They
have found that having fast food places by each
other does not take business away from the first
fast food place to be located there and instead it
actually increases the business for all fast food
places in the area.  Just a thought since I have not
seen anyone marketing externals for LiveCode.

Re: externalPackages

I see your point.

Changing the subject a little bit you mentioned
LiveCode is going to improve things so you can
actually do more external type code from within
LiveCode.  Are they going to be using Apples new
programming language Swift at all?

Re: externalPackages

I just watched the widget video and it
sounds really great.  The video like all
of their videos was well done too.

It sounds like Kevin wants more people
developing externals and that is good.

ListMagic highlight color

[JB]

I have a handler that when I double click a line
it gives me the option to delete the line.  I can
either cancel or delete the line and update the
list.

The problem is it changes my blue line selection
to gray and I want to have it selected blue again.
How do I update the selected line color to the
original line color ListMagic installed for lines?

Re: ListMagic highlight color

[JB]

The problem comes from using the answer dialog within
the script. After using it the field will not select the proper
color on the lines.

A simple fix is to not use the answer dialog from within
the list magic field.

Re: Window manager plugin?

[JB]

Hi Scott,

I put the script in my stack script and it continued to
show the answer dialog in the center of the screen.
So I replaced llc with “112,110” and  nothing changed.

Then I added "put the openStacks" into the mouseUp
handler where the answer dialog is called from.  If it
is at the very beginning of the handler it puts the open
stacks in the message box.  But if it is before or after
the answer script nothing is put in the message
box.

Re: Window manager plugin?

[JB]

Thanks Scott.

I cannot believe how dumb I am somedays.
The problem was I pasted the code as it was
in my openStack handler and after looking at
it I see they both call the same thing.

Your latest version fixed it.

thank again.

Re: Window manager plugin?

Thanks, Jacque.

It is nice to have some more code examples.  I was
able to get it to work okay but if I use answer warning
the warning icon does not show.  Is there a way to
get it to show up with this code?

Re: Church bell app?

America and society have changed drastically in the
last 10 years.

People are organized and many times they steal from
you are damage something you own simply because
they want to destroy you.  Aa a group they are like a
bunch of termites.  They each do their part no matter
lhow small it is because they know that even if they
each steal or somehow cost you a dollar if a hundred
of them do it to you a month you have lost one hundred
dollars.  They don’t stop at a hundred dollars and just
all keep attacking you in many different ways.

If I have a certain amount of characters

line of characters to see if they are there
and if so then delete them what is the
fastest way to do delete the characters

Hi,

Thanks for the reply.

I am saying if I have “ABC” in one string and the other string
has “KCFAJFCABC” then I want to delete the “ABC” from
the end of the second string leaving “KCFAJFC”.

Re: delete end chars

[JB]

Hi Richmond,

Wouldn’t that just delete the last char?  I need to
check for all characters in the first string to see if
they all exist in the same order of the last chars
of the second string.  I know I could use a repeat
to see if the characters all exist and then if they
do I could use a repeat that many times to delete
the last character.  I was thinking there might be
a faster or at least smaller way to write the code.
Would a regex be better and if so how do you
write the regex properly?

Re: delete end chars

[JB]

Thank you for the reply and code.

I can’t seem to get it to work right.
The only thing I could make it do is
if ABC is string1 and ABC us string2
it will delete string2 but if chars are
before the ABC in string2 nothing is
deleted.

Even so it is good code and I might
need to use it sometime.

Re: delete end chars

[JB]

I still can’t get it to work for some reason.  And the
first regex one ends up leaving me the letters that
I wanted to delete instead of leaving the other part.

After getting the others to work in a new stack I tried
them in the script I needed it for and the only one that
would work is the one Colin Holgate wrote.

It seems the ones that used “the text” int the script might
need to refer to a field and not a variable so I re wrote the
script to use a field and it still did not work.  I think it might
be due to the place in the script I needed it is nested deep\
in some repeat commands.

Once again thank you and everyone else for the help.

Re: delete end chars

You are right.  Thank you!

What happened is the variables were all
listed right in my code for the searching
and replacing and then I put the wrong
variable into the field I wanted to change.

thanks again.

Re: delete end chars

[JB]

You brought a lot to the table.  Test code is nice
ti have and I thank you for it.

I was thinking Peter’s would be faster and I wanted
to use it.  I got it working in a new stack with the code
the others wrote and saved it all.  They akk work in the
new stack but don’t work properly in the stack that need
it for.

The script has a few repeats in it and where I need it is
about as deep as you can get.  I have found when you
get real deep in repeats certain things don; work.  Like
if you compound your script into a single line which  is
good if it is deep in a repeat the engine can’t understand
the complex script.

thanks again!

Open App/file

[JB]

Is there a way to send a double click to
a file or application if I have the file path?
Or any other code that would allow me to
open a file or application?  I do not mean
I want a binary read/write I just want the
file or app to open like it does when I click
on it in the finder.

put empty into tReturnList
repeat for each line tLine in pData
put item pCol of tLine &cr after tReturnList

Re: join columns

[JB]

Hi Phil,

I am having trouble with the proper way
to write the combine pData by column.

I can split the columns and reverse them
like you show but how do you write the
code to combine them?  It looks to me
from the dictionary the column needs
to be a number but what line do I need
to put them on?

Re: join columns

[JB]

Hi Alain,

I am having trouble getting it to insert the column.
Here is the code I am using to access your function.

local dataToInsert, intoThisTable

on mouseUp
   put fld id 1056 into pData
   split pData by column
 put pData[4] into dataToInsert
   put insertAsColumn (3, dataToInsert, intoThisTable) into newTable
   put newTable into fld id 4738
end mouseUp

It puts the dataToInsert into id 4738.
What am I doing wrong here?

Re: join columns

[JB]

That was wrong.  It should be,  But it does
not give me a whole table.

on mouseUp
  put fld id 1056 into intoThisTable
  split intoThisTable by column
put intoThisTable[4] into dataToInsert
  put insertAsColumn (3, dataToInsert, intoThisTable) into newTable
  put newTable into fld id 4738
end mouseUp

Re: join columns

Hi Phil,

Thank you so many times!!!

It does work.  I was thinking i needed to add more to it
and never tried it like it was.

This is my first time with arrays.  So I was looking around
for infö and in the process came up with a good lesson on
arrays.

Thanks again!

Re: Delete columns... How?

[JB]

I am sure someone else
can do it better but this works.

on mouseUp
   put fld id 1056 into pData
   set the itemdel to tab
   split pData by column
 put pData[4] into tType
 put pData[3] into tSize
 put "size = empty" into tSize
 put pData[2] into tModDate
 put empty into tModDate —THIS COLUMN DELETED
 put pData[1] into tName
 put tModDate into pData[3]
 put tType into pData[1]
 put tSize into pData[4]
   put tName into pData[2]
   
   combine pData by column
   put pData into fld id 1056
end mouseUp

On this the column to delete would
need to be joined at the end.

Re: [OT] Spies under the bed.

[JB]

It sounds to me like the spies came out from
under the bed and are now in your bed.

Booz, Allen, Hamilton

They are in control of everything and in bed with
every politician and government agency.  They
are bank managers and corporate managers in
every private, industrial and government agency.
They are involved deeply in the DOJ, SEC, FBI
NSA, Homeland Security and anything else you
can think of and even things you cannot think of.

They are attorneys, prosecutors and judges so if
they want to destroy you even your own attorney
will help lose the case.  They control the news in
America.

In other words get used to it because unless they
are stopped nothing will change.  They control the
politicians in America so who ever wins a election
will be serving them and not the people.  it is what
is in their best interest that counts.  They are part
of the military industrial complex that Eisenhower
warned US about in his departure speech.

They are a global company.

Re: [OT] Spies under the bed.

[JB]

Hi Richard,

Don’t worry about it too much.  They
will tell you they love you.  This is all
being done for your own good.  They
care about you & want to protect you
from all sorts of things.

The only reason the spies came out
from under your bed and are now in
your bed is because they love you &
care about you.

In other words you are about to get
screwed.  Do not resist it will only
make it worse.

Filtering FIle Types

[JB]

If I have folder with thousands of files
I can use the Files and get a list of the
file names and it will end with the type
preceded by a dot such as .jpg.

I can set the item delimiter to “.” and do
a repeat to get the last item of each line
and I will have a list of all file types and
the name/line they are associated with.

If I want to filter the list to only include a
certain list of file types I can do a repeat
and check the type for each file name &
then provide a list of types to check such
as “png,db,gif.text” and say if if “jpg” is in
the list then do whatever like include or do
not include this file in the list.

What is the fastest way to filter a list of files
if you know the name and type of the file?
Would a regex be good for this?

Re: Filtering FIle Types

[JB]

I have not tried it yet but if it works
the problem is I might want to use
a variety of file types so the repeat
would filter one line at a time and
then you check for that type in the
list of types you will allow.

The way you provided would need it
to allow a list of types or I would need
to keep filtering so there might be a
faster way but I am not sure.

Thank you for the reply and code advice.

Re: Filtering FIle Types

[JB]

Thank you for the reply and code.

If I call it for every type I want then
I will need to splice it back together
with the other types I filtered after I
am done calling for each type.

I guess there comes a point when I
have added a certain amount of types
it will be faster to do one line at a time.

Thank you for the code!

You posted

Maybe that is why I get an error when I even put
the script into my button.

It works on LiveCode 6.6.2 and higher not Revolution.
Not to be critical of LiveCode I just happen to be working
or a project in the last version of Revolution Enterprise.

Re: How To: Delete columns of data

[JB]

That is fast but here are a few problems I
am having.

It looks to me like you can only delete one
column and then you use it again to delete
another column.

I am getting a list of the detailed files which
is a comma separated list of 11 items and I
only want to end up with 4 columns.  When
I use it again it looks like I need to calculate
the column I deleted to know which columns
I still need to delete.  Not major issue.  The
bigger problem is this scenario.  I deleted a
bunch of columns from a list of a little over
30,000 files and it worked but then I use the
open to select another folder of files and it
only had around 305 files but for some reason
it appears the memory is not cleared because
the cursor spins and won’t take me to the other
folder.  I use Force Quit and it list Revolution as
not responding.  It does not look like this is code
limited to newer versions of LiveCode so I don’t
understand why Revolution would quit responding.

Swift externals

[JB]

It sounds like Apples new programming language
Swift is going to be used in LiveCode.  Swift looks
similar to a scripting language.

Does anyone know when the official release of Swift
is and will it be possible to incorporate it into older
versions like Revolution?  It looks like Swift would be
a good way to write externals instead of Xcode 2.4
which is outdated.

Re: How To: Manage columns of data (was Re: How To: Delete columns of data)

[JB]

Hi Hugh,

Thank you again for the code.

When I first mentioned I tested your code I said that
for some reason it was causing me problems and I
would need to force quit the program,

A few days before that I replied to Richmond’s post
about spies under his bed.

My home page was Google and now it is Yahoo.  I
was attacked by MacKeeper and I personally think
it was done from Google and with their permission.
I also suspect they share the same management &
they are Booz, Allen, Hamilton.  I have been in a war
with them for over 20 years now and I continue  to
expose their criminal activity and abuse of power.

The reason why I sometimes have trouble with what
seem to be small things like not seeing the code did
allow more than one column to be deleted is because
I am being poisoned in my own home in such large
amounts I can hardly see plus it causes problems with
thinking and lowers the ability to learn,

The recent attack from MacKeeper prevented me from
accessing my bank account and when I would to to a
web site their ad would appear instead.

I believe the problem caused my computer memory to
over load and that is why I would need to force quit the
program.

I have posted this to let you know since I did mention
the problems happen when I used your code.

Re: How To: Manage columns of data (was Re: How To: Delete columns of data)

[JB]

I would like to clarify the part about the attack from MacKeeper
preventing me from accessing my bank account.  I mentioned
that I was also taken to MacKeeper instead of the websites I
wanted to go to.

The attempt to go to other websites was done from my home
page which was Google.

The attempt to access my bank account was done from my
banks web site which is Bank of America.  I would click the
button to sign in and instead of taking me to the next sign in
step I would see advertisements preventing me from logging
into my account.  I called my local bank and they gave me a
phone number to call.  The woman I spoke with at my bank &
the number I called were very nice.  The woman at the number
I called tried for a long time to help me log in and she could not
get me logged in so she gave me the number of their tech crew
and also transferred me to them.  After quite a while and many
different attempts he got me logged in to my account.  He was
not jerking me around and wasting my time and accomplished
getting me logged in.  I have used Bank of America for many
years and they did not personally attack me or waste my time.
Even so I suspect they share the same management and it is
corrupt management who intentionally left the door open for
the abuse and attack by MacKeeper.  That does not mean it
was Bank of America just because they employ BAH.

Re: How To: Manage columns of data (was Re: How To: Delete columns of data)

[JB]

I suspect MacKeeper is the culprit and
they are causing the problem to get me
and other to purchase MacKeeper.  It is
similar to the mafial coming into a store
and telling them we have noticed some
problems in the area and for a fee we
will insure you don’t have problems.  If
you pay they protect you if not they will
prove to you the problems exist.

The web site does not look false to me &
in the url it included MacKeeper campaign
in the name.

MacKeeper attacks are not new and you can
google them to see this is not the first year.  If
MacKeeper did not benefit from attacks they
would have made sure years ago people who
use their name maliciously were prosecuted or
at least exposed and stopped.

Considering authorizes ignoring the issue you
need to consider Booz, Allen, Hamilton control
the DOJ, NSA, CIA, FBI the news media and
many other things along with the politicians.

Maybe you are not being attacked and simply
believe in the tooth fairy and Santa Claus.  I am
closely involved with the abuse and I have sent
the news media thousands of emails over many
years exposing abuse.  That does not make the
reporters evil or out to get me.  They report what
they are told to report and if they attempt to report
this it will not be aired and they will not have a job.

The attacks on me are vicious and last summer my
two phone lines were disconnected for failure to pay.
One of the lines I had for over 30 years.  The problem
started in the end of June when I paid my bill on time
and they refused the payment from Discover card.  I
was not told the payment was refused so as far as I
knew it was paid.  In the last week of July both phone
lines and my internet all stopped. I am not allowed to
have a phone in my own hame now.  At the worst if I
was late on my payment for a month it would wrong to
disconnect my phone lines that fast and not even give
me a warning, especially since I have been a customer
for over 30 years with the same phone number.  I wes
without phone service for 10 weeks and I wrote them a
lot of letters and made sure they were paid in full.

If my DNS was changed the bank would not recognize me
and they would never have let me log in without explaining
why I have a different DNS and would tell me that was the
problem.  They are not idiots and don’t allow people to use
my account with another DNS and that includes me.

B of A did not have MacKeeper ads.  I can assure you that
they were told about the abuse during the time they finally
got me logged in.

If you can prove what they have not I am sure they would

I am glad you are done.

B of A had me go to the web site with

I was not thinking correctly and you are right
about DNS but it goes back to the same issue
of why do you think B of A techs would not be
aware of this and have me change my password.

Unless you have done their job I do not think you
have the knowledge they have.

So it does not matter if I know DNS or ISP because
B of A wants to protect me and would make sure I
was protected if I like it or not or if I understand it.

These post to suggest B of A do not know how to do
their job by suggesting I am wrong are ridiculous.

Provide some evidence and I will give it to B of A if it is
something we did not already discuss.

Re: How To: Manage columns of data (was Re: How To: Delete columns of data)

[JB]

I really do appreciate your help, Jacque.

The technician had me go to the site with
him on the phone line talking to me and 
had me enter my info.  He knows if I am at
the site and asked me everything I saw.

As for stealing my info he would be aware
if I had been compromised very fast.  His
questions would give him the evidence he
needed to promptly tell me to change my
password.

I was not at a fake BofA site unless I was
talking to fake BofA employees.  And if I
was why spend so much time with me and
then solve the problem?

The techs at BofA know my password already.
And I will tell you they know everything about
me logging in.  They know if I am using another
web browser or another phone to log in.  If I did
log in and anything unusual was detected it will
automatically block me.  If there was anything to
suggest I had ever been on a fake site they would
force me to change my password and take action.

Thanks for the help but you are wrong about me
being at a fake site.

Externals in Objective-C

[JB]

n theory any language that can build shared libraries and allows you to link 
with the provided glue code
could be used. However, in practice, some languages will require extra 
glue-code in order to provide an
environment in which their code can run. For example, to access Objective-C you 
will need to ensure you
set up its memory/exception environment in C wrapper functions before calling 
any Objective-C code.

Does anyone have a  copy or example of a C wrapper functions for 
memory/exception environment?

I want to write a external using Objective-C instead of C++.  Does anyone have 
example code of how
to write a external for Revolution using Objective-C?  It appears that even 
Swift might be able to be
used for writing externals in LiveCode and Revolution.  Does anyone have some 
example code that
will allow the writing of externals with objective-C or Swift?

Re: Externals in Objective-C

For anyone who is interested in writing objective-c externals
in LiveCode and Revolution here is a link to some code that
might work.  I am still pretty new to c++ and objective-c and
have not tried it yet.  If you get it working please post some
code.

c++ wrapper for objective-c link;

Re: Listing & Filtering files

Thanks for the info on the link for part 2.
I am color blind on reds and greens and
after you pointing it out I see it.  Before
that it kind of disappears and makes it
easy to miss.

Re: Listing & Filtering files

[JB]

Thanks for the advice and info.

Since Richard Gaskin already pointed
out the problem and even told them it
is color blindness related I won’t bother
them.

What is more important is the release of
Swift and how they are working it into the
ability to program externals for LiveCode.

Hopefully they take the time to make the
externals people build work on the earlier
versions too.  This would profit LiveCode
and anyone who sells or uses them.

Keeping the door open for RR users is good
business.

Progress Bar

How do I set the end value of a progress

Re: Progress Bar

[JB]

It does not really matter.  I realize the best
way is to set the end value at 100 and use
the percent value of how much has been
processed since there are limits on how
large the end value number can even be.
