LEP that will quit Chrome?

2019-02-28 Thread Keith Goebel via 4D_Tech

Hi all.
I am trying to formulate a LEP command from 4D v17.0HF3 Win on Win7 (although 
it will be deployed on Win Server 2016).

The idea is to quit Chrome from within 4D.
After lots of Google searches I have tried (in my development version)

$Command_t:="TASKKILL /IM /t chrome.exe"
SET ENVIRONMENT VARIABLE("_4D_OPTION_HIDE_CONSOLE";"true") 
SET ENVIRONMENT VARIABLE("_4D_OPTION_BLOCKING_EXTERNAL_PROCESS";"false")
LAUNCH EXTERNAL PROCESS($Command_t)

and
$Command_t:="cmd.exe /TASKKILL /IM /t chrome.exe"
SET ENVIRONMENT VARIABLE("_4D_OPTION_HIDE_CONSOLE”;"false") 
SET ENVIRONMENT VARIABLE("_4D_OPTION_BLOCKING_EXTERNAL_PROCESS";"false")
LAUNCH EXTERNAL PROCESS($Command_t)

Neither has any effect - Chrome stays running.
If I show the console with
SET ENVIRONMENT VARIABLE("_4D_OPTION_HIDE_CONSOLE";"false”) 
it flashes open and then is gone before anything can be seen.

Can anyone advise me what I’m doing wrong?
TIA, Keith

RE: Can'r run as a service on Windows 2016

2019-02-28 Thread Stephen J. Orth via 4D_Tech

I agree with Chuck here...

We never install our OEM system on the C drive, let along in the Program Files 
directory.  We always insist the server hardware be configured as C-Drive for 
Windows, D-Drive for data.

All our systems run as a service, with no special configuration required

Best,


Steve

I have found it is always better to Install program and data on a second drive. 
I do not run as a service but had many update problems and running problems 
when on c drive

Re: Can'r run as a service on Windows 2016

2019-02-28 Thread Ken Kuehn via 4D_Tech

Hi Paul, 

I use Inno Setup to create Windows installers for our 4D client and 4D server 
applications, the default install path for the server application is C:\Program 
Files. I normally set the data folder at the root of the C drive. However, the 
application that I support is installed at approximately 500 customer sites 
with various Windows and Mac operating system configurations, so I don’t always 
have access to or control over the environment where our 4D application is 
installed. For Windows Servers we still occasionally see 2008r2, but mainly 
2012 or 2016 Standard, and I am now getting customers asking about support of 
2019 Server. 

In a handful of situations with previous 4D versions I’ve seen instances where 
I needed to specify a logon account (either domain or local admin) to get 4D 
Server to stay running as a Windows service, but since the release of 4D v16 
(we’re currently using 16.4) I have had to setup the service  with s logon 
account so that the service starts and stays running.  If I just select the 
radio button for local system account and start the service, the status will 
change to running, but as soon as I refresh the services window it shows the 
service is not running. Also, checking the box for allow service to interact 
with desktop does not work.  It will show the service is running, but it’s not 
accessible from any 4D Client, local on the same machine or from any other 
workstation on the same local area network. 

In the past week I have run into 2 instances where I have upgraded from a 
previous version of our 4D application running on v13.6 or 15.4 to the 16.4 
version of our application.  The service ran without issue using the local 
system account option for both of those previous 4D versions, but now under 4D 
v16 the application will not run as a service. I’ve tried the local system 
account option, I've tried specifying a local admin account and also a domain 
admin account.  In all instances the server will show it’s running, but as soon 
as I refresh the services window it shows the service is not running. For the 
time being I have both 4D server instances running as an application under a 
local admin account until I can figure something out.

I’m open to any suggestions.

Version 13 is long dead and this has nothing to do with any version before 
ARRAY TIME was added. The problem is simple enough to work around, but the 
point of my post and (and Jeremy's) is that type handling and pointer 
dereferencing should be consistent and handled correctly by 4D. And the results 
between interpreted and compiled should be consistent unless it is documented 
not to be.

But the code works as expected in interpreted mode. So 4D knows it is a time 
array in interpreted mode, but not compiled mode?

Re: "Attempting to retype using a pointer"

2019-02-28 Thread Kirk Brooks via 4D_Tech

I just noticed something when I stepped through one of my examples - in
this case:
$to:=New object
$from:=New object
$i:=100
$from.ptr:=->$i
$to.ptr:=->$k
$to.ptr->:=$from.ptr-> // $k = 100 at this line
The value of $k changed as soon as this line runs.

I also wondered what would happen if I initialized $to.ptr to a nil
pointer. The answer is

C_POINTER($nil)

$to.ptr:=$nil  // $to.ptr = null

Nil is regarded as null in v17.

4D Web Log Out

2019-02-28 Thread Douglas Cryer via 4D_Tech

Hello folks,

Forgive me if this question has been asked many times before  but I am a bit 
stumped.

Logging on to 4D via a web page is relatively simple wither using the nasty 
dialog or rolling your own page to submit the httpauth details.

Logging off however is proving to be more difficult.

I can give the impression of logging off but the username and password seems to 
persist on the client browser so re-entering a previously visited page that 
pulls data just continues to work.  If I manually clear the browser cookies 
then the access gets denied but the 4DSID cookie cannot be cleared by 
javascript...

What are the correct steps to achieve this.  I need help...

True. In this case what we are really talking about is 4D's object
notation. I tend to use 'ORDA' for all the new capabilities and should be
more specific.

I find this an excellent application of using objects as containers for
passing parameters to and retrieving values from a method.

Since you mention OBJECT DUPLICATE you must be working with variables on a
form. In that context using Form removes the need to work with pointers
altogether.

Perhaps you didn't create $to and $from with New object before using them?
Try running this:

C_OBJECT($to;$from;$obj)
C_LONGINT($i;$j;$k)

$to:=New object
$from:=New object

$i:=100

$from.ptr:=->$i
$to.ptr:=$from.ptr

$k:=$to.ptr->  // $k = 100

To use the code as you wrote it you must also initialize the property you
are writing to:

$from.ptr:=->$i
$to.ptr:=->$k

$to.ptr->:=$from.ptr->  // $k = 100

But if this happens

$i:=100
$from.ptr:=->$i
$to.ptr:=->$k
$to.ptr->:=$from.ptr->

$i:=200

$k:=$from.ptr->  // $k = 200

This was a useful exercise for me. I didn't realize you could use pointers
this way in objects. I don't think it's a particularly good way to work
with them but it looks like there is some fairly rigorous type checking
going on under the hood. For example, I expected this to work:

$i:=100
$from.ptr:=->$i
$k:=$from.ptr

but it doesn't because $k isn't a pointer. However:

$i:=100
$from.ptr:=->$i
$to:=OB Copy($from;True)

$i:=200

$k:=$to.ptr  //  $k = 100

does work because I use the True flag to resolve the pointers to their
values. This also points out (discovered pun) the fact that within an
object properties are dynamically typed ($to.ptr is currently a number). OB
Copy was a great tool in pre-ORDA days as a way to build a template of an
object based on fields and then use it to create data objects.

Re: Crash on startup, v17.1 merged app

2019-02-28 Thread Randy Jaynes via 4D_Tech

1) Permissions issue on the folder on the Mac.

2) Did you install it using a signed installer or DMG so that OS X Gatekeeper 
recognizes it as a registered program.

This sounds more like #2 to me, but in the past I’ve solved #1 by creating an 
Applications folder inside the user’s home folder, and putting the application 
there.

Starting with High Sierra, I’ve been having to use a signed PKG installer I 
made with Packages.app

HTH,
Randy

Crash on startup, v17.1 merged app

2019-02-28 Thread Pat Bensky via 4D_Tech

Running a compiled & merged single-user app v17.1 on a customer's Mac (OS
v. 10.12.6), the app crashes soon after startup - before it has asked for a
data file.
Of course, it runs OK on any other Mac we try it on :)
If I hold down the Alt key as it's starting up, it never gets to the open
options dialog.
It just bounces in the cost a few times, then quits.
Here is the relevant bit from the crash log:

Re: "Attempting to retype using a pointer"

2019-02-28 Thread Chip Scheide via 4D_Tech

John,
I see the issue -- The time array is NOT an array of Time
using v13 (no Time array)
so I had to use a longint array, or a time variable which points out 
the problem.

I believe it is:
Even though there is a TIME ARRAY() command, the underlying array is 
not actually time but longint.

If you use code block 1 (below) you get an error that 4D was expecting 
an alpha numeric argument (HH MM SS is longint); however, if you use 
code block 2 there wis no error.

Code Block 1:
C_POINTER($1)
C_TEXT($val)

If (Count parameters>=1)
$val:=String($1->;HH MM SS)
ALERT($val)
Else 
ARRAY LONGINT(ah_Time;1)
ah_Time{1}:=Current time
_TEST (->ah_Time{1})
End if 

Code Block 2:
C_POINTER($1)
C_TEXT($val)
c_Time($Temp)

If (Count parameters>=1)
$val:=String($1->;HH MM SS)
ALERT($val)
Else 
$Temp:=Current time
_TEST (->Temp)
End if

Re: "Attempting to retype using a pointer"

2019-02-28 Thread John DeSoi via 4D_Tech

4D has improved over the years, but there is still a number of type handling 
inconsistencies. Only option seems to be to work around them by moving data 
into different variable types.

The method below (_TEST) works interpreted but gives a runtime error in 
compiled mode. Reported as a bug in 2016 for 4D 15. Still fails in 17.1

C_POINTER($1)
C_TEXT($val)

If (Count parameters>=1)
$val:=String($1->;HH MM SS)
ALERT($val)
Else 
ARRAY TIME(ah_Time;1)
ah_Time{1}:=Current time
_TEST (->ah_Time{1})
End if 

Here is another issue in 4D 17.

C_OBJECT($object)
C_POINTER($field)

$object:=New object("tableNumber";1;"fieldNumber";1)

$field:=Field($object.tableNumber;$object.fieldNumber)

The above works but the Field command won't compile: Too many parameters have 
been passed to this method.

What is the file path to the location where you have the exe and data
installed. You can only use c:\\program files for the exe not the data. For
that use c:\\program data or as mentioned install under a user account. In
which case it runs from c:\users\username etc.

RE: Can'r run as a service on Windows 2016

2019-02-28 Thread Epperlein, Lutz (agendo) via 4D_Tech

Pat,

Have a look at the docs:
https://doc.4d.com/4Dv17/4D/17.1/Registering-a-Database-as-a-Service.300-4203714.en.html

They recommend to run the server under an user account, if you want to use 
network shares, printers and so on. 
But we don't install the services this way, we stay at system account yet, and 
don't get any problems.
We don't have experiences with Windows Server 2016 (2012 R2 yet) and we don't 
use the feature of interacting with the desktop. And we are able to connect to 
server with a client from the same machine.

A question: how do you connect the client to the server? Which address do you 
use, localhost, an IP 127.0.0.1 or another IP, a named address? That could lead 
to problems with the firewall. In case you use localhost (or 127.0.0.1), the 
firewall shouldn't be involved AFAIK.

Regards
Lutz
