Ya gotta have a database and you gotta maintain it, because the rules change 
for a range of reasons. This takes me back to my programming infancy in 1988 
when I created a Hypercard stack that was filled with all the countries and 
major cities of the world. I'm a geography fan, so I thoroughly enjoyed do the 
research (pre-internet). You entered your local time and selected the 
city/country you wanted to know the time in and it would look it up and display 
it. The stack was called "What Time?" and it got an award from the Boston 
Computer Society. I distributed it as shareware (remember that concept?) and I 
sold about 10 licenses. Even got an order from Switzerland. Fulfillment was by 
mail.

Thanks for the trip down memory lane. Sorry for the diversion.

RE: Printing A3 format on windows when scaling is not possible

2018-09-26 Thread Piotr Chabot Stadhouders via 4D_Tech

Hi Olivier,

The example in the docs for the command PAGE SETUP is indeed kind of what I am 
talking about.
But instead of having different forms with a scaling setting I have different 
page setup forms with a “paper size” setting (A3 portrait, A3 landscape), 
because also forms with a scaling setting (set  on printer 1) have no effect 
when used with printer 2 when this printer is unable to scale

I know I can get the paper width / height and with some math move / resize 
objects on the form

However, we already have tens of output forms, and unfortunately not only with 
a few columns, but with a lot of fields on different parts of the form
Moving around these fields is no option for me.

My boss doesn’t understand why this scaling is a problem, because as he sees it 
“there are a lot of applications where printing a lot of small sized info on an 
A4 paper is no big deal at all”

Gr,
Piotr




Hi Piotr,

I guess, you are doing what is described in the documentation for PAGE SETUP:

http://doc.4d.com/4Dv16/4D/16.4/PAGE-SETUP.301-3978038.en.html

The idea of "AUTOMATIC SCALED PRINTING" ?

Am I correct, that the goal is to print a list scaled in order to fit on a 
"standard" size (e.g. A4).

If my assumptions are correct, then we are dealing with the problem "a piece of 
paper has limited size, screens have scroll bars".

One solution is indeed to scale. But... as the doc for SET PRINT OPTION says: 
"Be careful, some printers do not allow you to modify the scale..."

The other solution is to distribute the width of the columns of a report (e.g. 
a Listbox) relatively to the available width of the paper.

The available width on paper depends on the printer (paper size, printable 
area) and print options (landscape vs. portrait).

In my component, I have a method that does this kind of printing. The idea at 
the beginning was to have a generic way to print listboxes, but it could also 
be a 2D array:

https://flury-software.ch/a-swiss-army-knife-for-4d/

Check out the method "Uty_PrintListBox"

Disclaimer: this is not a magic solution. It's just an other try to print what 
can be endless on screen (scroll bars) to the limited size of paper.

HTH,

Olivier

Hi Miyako,

Ok, I understand what you are saying, and in some cases I already use the SET 
PRINT OPTION command

But when I want to print a report without interaction with the user, and I want 
to print it to a certain paper size, I can do two things I guess:

  1.  Use SET PRINT OPTION with Paper option and value1=”A3”. Does using paper 
name = “A3” always work? Or do I have to get the paper names first and find 
some paper name with A3 in it?
  2.  Use SET PRINT OPTION with a custom width and height. Does this always 
work, for every printer?

Re: How to get the current time in a specified time zone

2018-09-26 Thread Pat Bensky via 4D_Tech

After trying various complicated methods of calculating the different time
zones, the final method was actually quite simple.
I needed to set up an email-sending routine to send emails out at 7AM for
each time zone. This is what I have. This is currently being tested :)
Please feel free to point out any obvious flaws!

  // get the current GMT time

*XML DECODE*(*Delete string*(*String*(*Current date*;ISO date GMT;*Current
time*);20;1);$tTime)

$CurrentHourGMT:=*Num*(*Substring*(*String*($tTime);1;2))

  // get the difference between current GMT and 7AM

*If* ($CurrentHourGMT>=7)

$TimeZoneDiff:=($CurrentHourGMT-7)*-1  // gives us a starting point for
where it is currently 7AM

*Else*

$TimeZoneDiff:=7-$CurrentHourGMT

*End if*

$Current7AM:=$TimeZoneDiff

*For* ($i;1;24)

*  QUERY*([Emails];[Emails]gmt=$Current7AM)

  // send the emails

*Case of*

*:* ($Current7AM=0)

$Current7AM:=-1

*:* ($Current7AM=-11)

$Current7AM:=12

*Else*

$Current7AM:=$Current7AM-1

*End case*

$lastHour:=$CurrentHourGMT

*While* ($CurrentHourGMT<=$lastHour)

*DELAY PROCESS*(*Current process*;$DelayTime)

*If* ($testing)

$CurrentHourGMT:=$CurrentHourGMT+1

*Else*

*XML DECODE*(*Delete string*(*String*(*Current date*;ISO date GMT;*Current
time*);20;1);$tTime)

$CurrentHourGMT:=*Num*(*Substring*(*String*($tTime);1;2))

*End if*

*End while*

End For // 24 iterations

The only thing I'm not sure about is how various time zones change in their
relationship to GMT (eg Summer Time etc.) For example if Country A is
normally on GMT -8 but they're currently on Summer Time so 7AM in that time
zone is CurrentHourGMT-8+1, how do we account for that?


One idea I have is to get a list of timezones using sudo - eg

sudo system setup -listtimezones

but I haven't been able to get that to work using LEP - eg

*   C_TEXT*($result)

  $cmd:="sudo systemsetup -listtimezones"

  *LAUNCH EXTERNAL PROCESS*($cmd;$result)

$result is always empty - I guess I'm doing something wrong!
Then maybe go through each timezone, temporarily switch the machines's zone
sudo system setup - settimezone timezone

Get the current time in that zone and calculate its difference from GMT ...
Save all those results into a lookup array.

Any ideas about that?

Re: Printing A3 format on windows when scaling is not possible

2018-09-26 Thread Jeffrey Kain via 4D_Tech

It used to be that if you didn't call PAGE SETUP you'd end up with really weird 
and random print job settings, like  copies etc.. You had to tie this 
command to the page setup information saved with the form with a reasonably 
similar printer.

So it's no longer needed at all?
