Re: What is wrong with this statement? Corrected
Well, that is quite odd given that is "just" an array after all but internally
it seems 4D is treating it is something a bit different?? It seems like an
interpreter bug to me...

OK - I tracked it down.
It has to do with Listboxes
a 'normal' array works as expected, however, if the array is a listbox
column (array based - did not try a selection listbox) then the code
fails.
For some reason, when referencing the contents of a listbox column the
value inside the { } can not be an expression (at least in v13). Even a
simple expression {2+8-6} fails.

version (>v13) then I am working in...

Re: What is wrong with this statement? Corrected
yes - an intermediate value works, I was more wondering why the
original statement will not work...
as it appears to be a perfectly valid statement.
Replacing the array element reference with a simple math formula works.
i.e.
Array{2+8-6}
give the value of element 4 (assuming there is one)
there should not be an issue with a valid formula inside set
brackets
ohh well...

Re: What is wrong with this statement? Corrected
Does it work if you do use an intermediate value? e.g.
$value:= $Return_ptr-> {$Item}
$Result:= $Column1 ->{$value}

My bad -- the correct line of code that is failing is:
$Result:= $Column1 ->{ $Return_ptr-> {$Item} }

What is wrong with this statement?
Given:
-- $Return_ptr is a pointer to a longint array
--- Array has 2 elements values of (4, 2)
-- $Column1 is a pointer to a different array which has 10 elements
--- all elements are populated
-- $Item is a longint value as index to the array
-- $Result is a longint variable
(spacing added for clarity)
$Result:= $Column1{ $Return_ptr{$Item} }
4D throws an Error 52
$Return_ptr{$Item} = 4
$Column1 {4} = 100
inserting parenthesis around ( $Return_ptr{$Item} ) does not resolve
the problem.
Any idea why 4D is choking on this line of code??
Thanks
Chip

Re: 4D v17r4 Windows Print To PDF ignoring PAGE SETUP
Paper names also differ across different drivers on the same platform. In 64-bit Mac 4D, SET PRINT OPTION fails with an OK of 0 if you specify a paper name that doesn't exist on your current printer, so you either need to get an array of all the available paper types and write some code to figure out what you want, or specify height and width in pixels. -- Jeffrey Kain jeffrey.k...@gmail.com > On Jul 8, 2019, at 8:40 PM, Tim Nevels via 4D_Tech <4d_tech@lists.4d.com> > wrote: > > Paper names can be an issue cross platform.
