I assumed that you were "appending" column instead of inserting column before 
existing columns.

Optimization is fun although some developers are against it.

Assign multidimensional array

2017-12-04 Thread stardata.info via 4D_Tech 

Hi All,

I need to copy a multidimensional array ($A) into another of the same 
dimension ($B).
Is necessary do a cicle and assign every single position or is possible 
to do other?


ARRAY TEXT($A;1;2)
ARRAY TEXT($B;0;2)
$A{1}{1}:="1"
$A{1}{2}:="2"
$P:=Size of array($B)+1
INSERT IN ARRAY($B;$P;1)
$B{$P}{1}:=$A{$P}{1}
$B{$P}{2}:=$A{$P}{2}


Thanks
Ferdinando

maybe it is the remote data call/population of the listbox arrays?

for comparison try:
- populate the listbox from local (4D) data

not sure if Copy Array will copy multi-dimensional arrays - you could 
try.
but as worst case:

(assumes $B is already denied as having the same dimensions as $A)
For($i;1;size of array($A))
 copy array($A{$i};$B{$i}
end for

Strange problem with v16 and Launch External Process in a component

2017-12-04 Thread Adrian Boone via 4D_Tech 

Hi all,

We have a component which uses Launch External Process to call an 
accountancy package (Moneyworks) via the command line (Windows and Mac), 
and have just recompiled it for v16 (that's another story...). Now, when 
any component methods which use LEP (i.e. most of them) are called from 
another method in my test database, they always return ok, and the 
output and error variables are always empty. There's no noticeable delay 
in the debugger so it looks like the LEP call simply isn't happening?


Now for the really weird part, I have a form with some common test 
methods linked to some of the buttons - if I call the exact same code 
with the same parameters from a button on the form, it works!


If I open the source code for the component, the methods all work fine. 
I've tried setting the _4D_OPTION_BLOCKING_EXTERNAL_PROCESS environment 
variable to both "true" (which is what I want) and "false" immediately 
before the LEP call in the component, but it makes no difference.


This is happening on Windows 10, with v16.0 64-bit, v16.2 32 bit, and 
with the component compiled for just 32-bit, just 64-bit, or both.


Any bright ideas out there?

Thanks,
    Adrian

RE: poor performance LISTBOX INSERT COLUMN

2017-12-04 Thread Piotr Chabot Stadhouders via 4D_Tech 
Hi Chip,

When the form is first displayed there are no elements in one of the arrays in 
the listboxes
Only after certain user action, like pressing a button, the arrays are 
populated, so this isn't the problem

Furthermore, I am not able to test with local 4D data because, surprise, we 
don't use the 4D datafile at all. We populate the arrays with Oracle data.

Gr,

Piotr

Rearranging object entry order

Hi,

In search of a performance problem in 1 of our forms I am asking for some 
advice.

I have succeeded in analyzing 10 4DDebuglog.txt files (using an Oracle DB 
by the way) and have come to following :
The problem is with the execution time of the "LISTBOX INSERT COLUMN"
The performance of this command is very poor compared to other commands.
In fact, it takes about 10 times longer than every other 4D command in the 
logs

The LISTBOX INSERT COLUMN command takes on average 0.0286 seconds to 
complete, tested on a Intel Core i7-4710MQ 2.50GHz laptop
No big deal you could say, but for a couple of our forms it IS a big deal
We have a form with 27 listboxes on it, all dynamically build, with a total 
of 477 columns

So 477 * 0.0286 seconds takes up 13.6422 seconds
This is all done in the On Load event so the user must wait terribly long 
for the form to show up on the screen

My question :
Do you think this performance of LISTBOX INSERT COLUMN is acceptable / 
normal behavior?
Can someone confirm this performance?
Is there something, other than putting listboxes on other pages, I can do 
about this?

Thanks in advance,

Piotr

no ideas - but I ran into similar issues in v13, on windows.

LEP calls to OS for file level actions (copy, rename etc) everything 
empty, everything "OK" - not so much.
Run *same* exact command line code from cmd.exe everything worked as 
expected.

On Mac - no issue.

Port 80 Security Scanning - e.g. Qualys

2017-12-04 Thread Randy Engle via 4D_Tech 
Our company and at least one other 4D developer have recently been hit with our 
customers doing a security scan of our 4D based web applications.

In this particular case, they are using a service from "Qualys" that throws 
everything, including the kitchen sink at our web application.
In a lot of these cases, they are running these scans internally, inside of 
their own network and behind their main firewall.
(i.e. protection from mean, rotten, nasty, disgruntled employees that are doing 
bad things on their network)

4D Web server is not designed to handle many of the reported issues, such as 
DDOS attacks, "Slow HTTP Headers", etc.

The cyber security teams at our customer sites are quite adamant that "we" need 
to handle all of this stuff.
In most cases, saying:  "No, we don't handle that, you need to handle it", 
falls on some pretty deaf ears.
These cyber security teams live and breathe for the explicit life purpose of 
finding security holes, no matter how obscure and unlikely.
Basic unquestioned attitude is "We find it, you fix it" period.

So, the "answer" is to put a firewall of some sort in front of our web 
application, i.e. likely on the same machine as our web server application.

We don't have the staff resources to invest in the time it might take to get up 
to speed to handle all of these security issues and implementing a solution 
using, e.g. NGINX or Apache, or other.

So, we are looking for someone who is quite proficient at setting up a solution 
using the above (preferably NGINIX ?, if this will do the trick), to handle 
whatever a scan from Qualys can throw at it.

If you are that person, or know someone who is, please contact me off-line.

Much appreciated.

Re: Strange problem with v16 and Launch External Process in a component (solved - user error)

2017-12-04 Thread Adrian Boone via 4D_Tech 

Hi John,

It turns out that it was a false alarm after all - what I thought was an 
exact copy was missing a space in the path to the executable (which 
explains the immediate return in one case), combined with a bug in the 
component which didn't return false when the executable path didn't exist.


Of course if I hadn't sent this email, I'd never have spotted that 
missing space!

Re: Assign multidimensional array

2017-12-04 Thread Kirk Brooks via 4D_Tech 
Ferdinando,
Copy array works fine with 2D arrays if you want $B to be - a copy - of $A.
But it sounds like you need to _append_ the elements.

You can also use COPY ARRAY on specific arrays within the 2D array.
Example:
$A has 4 'arrays' with some number of elements in each array. I have $C
that I want to copy to $A{2}:

COPY ARRAY($C;$A{2})

​This is equivalent to

ARRAY TEXT($A{2}:Size of array($C)) ` assuming text arrays

For($i;1;​
Size of array($C)
​)

$A{2}{$i}:=$C{$i}

End for​

Resize SVG_Use

2017-12-04 Thread truegold via 4D_Tech 
Hi All,

I’m in the process of changing some SVG routines to be a bit more efficient (I 
think).

Miyako showed me how to embed svg images as “defs”:

$defs:=SVG_Define_symbol ($domSvg_ptr->;"defs”) 

so I could reuse the graphics without reloading them several times. This part 
works perfectly.

Previously I would read the image from disk and resize and place:

$tDom_Image:=SVG_New_image ($$domSvg_ptr->;$image_t;$x;$y;$w;$h)

Worked great! no matter the size of the original svg image on disk which are in 
the neighborhood of 1000 pixels width/height (although there is variation). And 
I can’t set the originals to a fixed size because the end user can change the 
same image, in different places of the svg document, to different sizes. So I 
need to managing the image sizes dynamically.

Anyway, now that I am accessing these “defs” images using:

$glyph:=SVG_Use ($domSvg_ptr->;$id;$inX;$inY;$size_IntrcG;$size_IntrcG) 


I have to both resize the image and make sure it stays at the x/y coords I need.

But it’s not!

To reset the size I believe I have to use (0.02 being used for testing):

SVG_SET_TRANSFORM_SCALE ($glyph;0.02;0.02)  


To reposition at the x/y I believe I have to use:

SVG_SET_TRANSFORM_TRANSLATE ($glyph;$inX;$inY)

The scaling seems to scale BUT the translate is not placing the images at the 
x/y location I need. Although, the attributes for the object look correct:

height - 14
transform - scale(0.02,0.02)
width - 14
x - 660
xlink:href - #S09
y - 660

I am assuming (until I know better) that these values are correct.

So I must be missing something? How do I control both the height/width (I think 
I am) and the exact x/y placement when I am creating an image using SVG_Use?

Anyone?

Thanks,
John…

Ref: Resize SVG_Use

2017-12-04 Thread truegold via 4D_Tech 
Hi All,

Note: If I apply the transform immediately after I create the symbol:

$symbol:=DOM Create XML 
element($defs;"image";"id";$name;"xlink:href";$image;"x";0;"y";0;"width";$width;"height";$height)
   
SVG_SET_TRANSFORM_SCALE ($symbol;18/$width;18/$height)

That seems to work and would be fine if all I needed were uniform sizes in the 
doc. In this example I am resizing them so they are 18 by 18 pixels. But as 
indicated previously the end user can set a size property to enlarge or shrink 
these sizes for the same symbol in different parts of the doc. So I need to 
resize and reposition where they are actually used.

Not sure if this is a clue or…

John...

translate offsets the x/y by the value specified.
the x/y you pass are not absolute coordinates (unless, of course, the x/y in

Agree!

I have tested setting the x/y w/h to 0 thinking that it would apply correctly 
but the svg looks like this:

Re: Ref: Resize SVG_Use

2017-12-04 Thread truegold via 4D_Tech 
Hi,

As an aside I am testing in a small sample and opening inn the viewer.

if I use this line:

SVG_SET_TRANSFORM_TRANSLATE ($glyph;$inX;$inY)

it works great! Starts the draw exactly at the x and y.

But if I add this line:

SVG_SET_TRANSFORM_SCALE ($glyph;$_w/$width;$_w/$height)

Then it goes from it’s correct location and jumps to the 0,0 origin I think..

BTW, I am using 4D v16R4 if that matters.

Maybe there’s a better ay to scale? I need to to scale the images based upon 
their original size (width, height) down to what ever the end users selects. 
Usually (in pixels) 14, 16, 18, 20, 24, 28, etc. These need to transform based 
upon the original width and height (usually close to 1000) to a small 
percentage.

Is there another way? A better way?

Thanks,
John…

Ref: Resize SVG_Use

2017-12-04 Thread truegold via 4D_Tech 
Hi,

Does the SVG_SET_TRANSFORM_SCALE  change the image size and also the the area 
size? In others words (even though the xml in the 4D SVG Viewer doesn’t show 
it) is 500 pixel width still 500 pixels after the size transform? Or is 500 * 
scale?

I'm asking because as soon as I change the scale then the x and y begins 
shifting in the picture.

When the scale is 1 things move and align pretty well.

When the scale is .90 then the image shifts to the left and top as the image 
also shrinks

When the scale is .75 (and so on) then the image shifts to the left and top as 
the image also shrinks.

Perhaps that is the problem and I have a setting that needs t be set 
differently?

Thanks,
John...
