Slow characters visualization

[stardata.info via 4D_Tech]

I All,

I notice that the slow in characters visualization, is always, even if the 
method have 10 rows.
When i write into one method the cpu consuming of 4D V15.5 is around 12/15%, 
like if 4D do a big work in interpretation of a code that i write into a method.
This only on 4D V15.5 in other version of 4D all is normal.

Only i have this issue?

Thanks
Ferdinando

Hi all,

I use 4D V15.5 on windows.
Sometimes when i write a method the editor is not fast responsive, in
fact i can see the character digited only after one second.

Someone know the reason, and how i can solve?

Thanks
Ferdinando

Re: SET UPDATE FOLDER

[Keisuke Miyako via 4D_Tech]

Finder on macOS does not impose control over its windows the way Explorer does 
on Windows.
you should be just fine without having to resort to such tricks.

Re: SQL Fail On Windows

[Keisuke Miyako via 4D_Tech]

is this client server and compiled?

it seems certain local variable names just don't work over the network.
I would try using the "execute on server" method property and let the code run 
on server.

SQL Fail On Windows

[Allan Udy via 4D_Tech]

Hi All,

Currently using the following example code from the Knowledge Base to 
determine the AutoIncrement status of a field:


C_LONGINT($1;$table_id_l)
C_LONGINT($2;$column_id_l)
C_BOOLEAN($0;$autoInc_b)

If (Count parameters>=2)
   $table_id_l:=$1
   $column_id_l:=$2
   Begin SQL
   SELECT AUTOINCREMENT
   FROM _USER_COLUMNS
   WHERE TABLE_ID = :$table_id_l
   AND COLUMN_ID = :$column_id_l
   INTO :$autoInc_b;
   End SQL

   $0:=$autoInc_b
End if


On my Mac's and Windows 10 machine it operates fine.  On our clients 
Windows machines we get an error about $table_id_l not being defined.


We haven't used SQL much... is there some underlying software that needs 
to be installed on a Windows machine to make it work correctly?


Cheers
Allan

Re: LEP - and Batch files

[Chip Scheide via 4D_Tech]

robocopy c:\hope c:\hope2 /MIR
This example will mirror what is in c:\hope into c:\hope2 and purge any 
files in the hope2 directory that do not exist in the hope directory. 
Use the /mir switch cautiously since it will be deleting files that do 
not match in the destination directory.

 Chip,
 
 have you tried to change the .bat file to eliminate the ‘cmd’ call
 and run xcopy directly, so that .bat would read just:
 "xcopy   2>> ”
 
 And then call the .bat directly in your LEP statement?
 
 Why do you need that “cmd.exe” for?

Re: 4DLINK

[Spencer Hinsdale via 4D_Tech]

Hi Pavel,

See if you can use LastDataPathLookup, ByAppPath:
http://doc.4d.com/4Dv16/4D/16/LastDataPathLookup.300-3130241.en.html

If you Build your application (app_sss.exe) using XML Keys, you:
- use v16
- set Compatibility option for Use New Architecture--see bottom of this page:
http://doc.4d.com/4Dv16/4D/16.1/Compatibility-page.300-3373287.en.html
- Build with the key above

This is a great solution for distribution.  Each target machine remembers each 
Data File for each App.

There are other solutions (DateName=StructureName AND in-same-directory, Key 
for DefaultDataFile) if _you_ control the target machine.

Re: LEP - and Batch files

[Chip Scheide via 4D_Tech]

sorry, i mistyped.  The batch file does NOT contain the cmd.exe 
reference only the copy command.
I have looked at the OS - it *is* 32 bit windows 7. There is only one 
copy of copy.exe.

I am giving up on this line of inquiry. 
It appears to me that there is something fundamentally broken with LEP 
and v13.5.
The batch file works as expected from the command line, & from the 
explorer interface (i.e. double click), but fails from LEP; and so far 
NOTHING has made the slightest bit of difference in getting the batch 
file to function as expected when called from LEP. The batch file does 
appear to be executed - as in an error file (empty) is generated when 
requested by the batch file.

I started down this (endless it seems) rabbit hole by trying to execute 
the xcopy command directly from LEP - but that failed as well, even 
when the exact same command was given to the command line. 

So.. 2 different approaches to get the same functionality, using xcopy, 
with no functional result. Something in LEP is broken (at least in 
regards to this specific command). I do not know what, I can not change 
it, 4D will not change it now. 
I am moving on to a different  means of attempting to accomplish the 
same task.

Re: 4DLINK

[Pavel Cerny via 4D_Tech]

Hi,

Under WIndows I have 2 or more identical applications in different
directories with different filename datafiles.
For example :
C:\A\app_sss.exe   C:\A\Database\app_sss.4DC and app_sss.4DD  - it is OK
C:\B\app_sss.exe   C:\B\Database\app_sss.4DC and app_bbb.4DD - when I update
the application, I always have to select the datafile again, can I set up
for exe (4dc) which datafile to open?

Thanks
Pavel
