When you say you changed the "publication name" does that mean you
changed the actual "project" name (the .4DB/.4DC filenames)?

You should or you might well have both of them using the same prefs folder.

Foundation 3.7.1-based app to 4D v2004

2009-11-26T20:41:14Z

I'm currently updating my client's Foundation 3.7.1-based program to 4D
v2004, in order to provide a few new features and improve compatibility
with Windows Vista.

I plan to eventually move them to Foundation 5 and 4D v11, but their
current budget is limited, and some functional additions are needed now.
The same problem would prevent me from moving them to Foundation 4, since
so much of the interface would need to be changed, and also the client
doesn't want another learning curve at this time. I'm trying to save the
big effort for moving them to v11 and Foundation 5 when the time comes.

Most of the conversion has gone pretty well, but I'm finding that the
Foundation 3.7.1 keyboard shortcuts, which are used to trigger menus and
call methods, are being ignored under 4D v2004 on Windows XP.

Does anyone know of a technique that I can use to fix this?

-9979 Error

2009-11-26T20:38:54Z

Hi,

I have a scenario where we rolled out a customised password system. The
administrator user executes a method (4D 2003, Mac) which updates 4D's
built-in password for each active user from a selection of password records.

This has been in use for some years. Recently, the admin user kept
encountering a -9979 error code when the script was run. When I run the
same script logged in as designer, it went through with no errors. The
problem resulted from executing the command "Set User Properties". I've
confirmed that the selection of records used to update the passwords are
those that have a matching password account in 4D's password editor. What
could have gone wrong out of the blue?

Regards,

Ronnie Teo

Change Enter Key

2009-11-26T19:07:49Z

Is there a way to change the behavior of the Enter key (numeric pad) so It
wont work as VALIDATE until the user reach the last field of the Input form?
I thought I can call from the object metoth to a filter key routine?
Is there a more efficient way, I'm migrating from Omnis to 4d and in OMNIS
there was a SET NEXT ACTION command so you can change from OK to TAB
behavior.

I will appreciate any help in this matter

You will need to have unique port number for the client connections
for each instance of 4D server you are running. (You do NOT have
control over the IP address for client connections.)

Jeff,

Yes, after I posted the message, I realized that this is a local issue with the client. I will talk with the Network Administrator on Monday, and see if I can get him to give me an exception for the 4D v11 SOL installer. If not, I'll just do a copy of the files over to the server

Re: 4D v11 Component Architecture

2009-11-26T16:20:46Z

Walt

Some further thoughts...

1. Something you'll have to manage is how to initialise components,
especially if they have their own data that they need to manage
(whether in variables/arrays/blobs or in records). Currently,
components do not run any code automatically when they are loaded.
This is touted by 4D as a security feature, but in practice it means
that your host database needs to be aware of the entire universe of
possible components that it can use, and have the ability to run their
initialisation code if it detects that they are present.

2. Components can't be unloaded at present without also taking down
the host. This is an issue for databases that need high availability,
so while it might be nice to be able to modularise functionality as
you are suggesting, in practice for the client the database still has
to be shut down in order to use any new or updated component that you
supply, so their experience is much the same as if you supplied all
the functionality in one structure file. The difference with multiple
components is that you get to develop stuff in a different sequence.
Although Mark warns against lots of components affecting startup
times, I have yet to have a problem with that. I use the 4DPop series
of components (about 10 altogether) and startup times are as quick as
I could wish for.

3. There are other ways to provide updateable functionality. For
example, the Web Area with hybrid Javascript functions/4D bad-url
callbacks embedded in a page that gets refreshed periodically/on
demand. You wouldn't even have to take down the application to make
new functionality/corrections available. The Web Area isn't perfect,
but you could easily have a global library of JS functions that's open
in an invisible window (so it executes, but doesn't display). In this
case your host application is more likely to be the API that the Web
Area JS functions program against, rather than the other way around!
But I start drooling over the interfaces that are now possible using
JS... things that are just flat-out impossible in 4D are often already
in an open-source framework somewhere that you can just reference and
use. Google and MS will host the script for you so you don't even have
to include it in your applicaiton. In fact, almost your entire
application could be done in JS, and you could just use callbacks into
4D via "bad" URLs (trapped by the Web Area, which calls a filtering
method, from where you can dispatch the call to the right spot) for
getting data into and out of the Web Area via XML or JSON or some
scheme you make up yourself. Should be lots of fun!

Mark and David,

Thanks for your comments and insights. I like the idea of an "API" approach
to 4D coding, although I can see that the fact that a component can only be
opened by one developer is a limitation - I had not thought of this.

The idea of modularizing production code is what attracts me to components;
we can create a series of "black boxes" for which the entry points are well
documented, so that all developers on the project know how to get data in
and out of them.

Reading Mark's message, I realized that I may have to modify my idea of
having one shell application, with all the action happening in several
components. If there is a practical limit of just a few components before
startup performance suffers, I'll have to crank that fact into my thinking.

It is always possible that 4D might improve its startup handling of
components as time goes on, so let's hope for that.

Thanks again, guys; your insights are quite helpful.

Re: Empty PDFs with 'SET PRINT OPTION (9;3;$docname)'

Steve,

Hi. I remember having a similar problem with zero size files like this. I
think it's something to do with getting the print options immediately before
you print, do the printing and then immediately restoring the saved print
options. Otherwise the data disappears into some unknown void...

Narinder.

How to Run Multiple Instances of 4D v11 Server?

2009-11-26T11:16:38Z

Dear All,

Hi. I'm trying to set-up a test 4D v11 Server on our server box - we have
sufficient client licences to facilitate this. Our production 4D v11 Server
is backed up and has a log file associated with it - I don't need these for
the test server.

I changed the publication name and broadcast IP of the test server but it
still wants to backup and generates some errors on launch - it seems like it
is still sharing some preferences with the production server.

I couldn't find any information in the KB or in the NUG archives about this
- if anyone knows of a definitive 4D guide or wishes to share their own
personal experiences I would be interested to read them. Thanks.

Regards,

Narinder.

Re: 11.5 change in behavior of SET DATABASE PARAMETER?

2009-11-26T11:14:08Z

AFAIK, there're 3 bugs in v11.4hf7 regarding SET/GET DATABASE PARAMETER on
sequence number.

1) SET DATABASE PARAMETER vs GET DATABASE PARAMETER

After setting SET DATABASE PARAMETER, using GET DATABASE PARAMETER return
dismatch sequence number. 4D claimed this is fixed.

2) GET DATABASE PARAMETER vs Sequence Number

GET DATABASE PARAMETER return mismatch result from Sequence Number command
(only happen on client/server but works fine on local mode. 4D claimed
it's unreproducible).

Nonetheless, it's confirmed to be fixed in v11.5.

3) SET DATABASE PARAMETER on others (forgot which one, please refer to its
fixed buglist) affect Sequence number.
4D claimed it's fixed.

Re: Substring(;1;MAXLONG ) crash in 4D 11.5 final

2009-11-26T11:01:17Z

Actual case is much more complicated. I save contents of a pointer array pointing to another arrays (including pointer arrays pointing to another arrays) and variables to blob using (extremely fast) VARIABLE TO BLOB with header information. In the data I have saved blob containing string arrays to blob. Much later when I read the data my code checks arrays match and if string arrays are of same element length. If they are not then you can not read array using BLOB TO VARIABLE. In this case I start reading directly every element from blob and copy to new array. If new array string element length is smaller than saved element length then code has to use Substring. It was easier to read max length of the string element and use substring than to add another if in loop.

My v6.7 code was like this:

$_prf_lArrToLen:=_arr ElementMaxLength ($_prf_pData) `check array element max lengths
$_prf_lArrFromLen:=_blob StrArrElemLength ($_prf_pBlob;$_prf_lOffset)
...
For ($_prf_lArrIndex;1;$_prf_lArrFromSize)
If ($_prf_lArrIndex%200=0)
IDLE
End if
$_prf_pData->{$_prf_lArrIndex}:=Substring(_blob StrArrElemet ($_prf_pBlob;$_prf_lOffset;$_prf_lArrIndex);1;$_prf_lArrToLen)
End for

_arr ElementMaxLength returned MAXTEXTLEN if $_prf_pData pointed to text array.

In v11 I changed automatically MAXTEXTLEN to MAXLONG and then I got the bug.

My current fixed v11 for loop:

For ($_prf_lArrIndex;1;$_prf_lArrFromSize)
If ($_prf_lArrIndex%200=0)
IDLE
End if
$_prf_tTxt:=_blob StrArrElemet ($_prf_pBlob;$_prf_lOffset;$_prf_lArrIndex)
If ($_prf_lArrToLen>=$_prf_lArrFromLen)
$_prf_pData->{$_prf_lArrIndex}:=$_prf_tTxt
Else
$_prf_pData->{$_prf_lArrIndex}:=Substring($_prf_tTxt;1;$_prf_lArrToLen)
End if
End for

It is true that my example code has no value by itself but I think you are missing the point.

I remember there has been discussion should we able to crash 4D Server with 4D code. I was just trying to warn my fellow developers of very simple case where just released 11.5 crashes in perfectly valid code. Older versions of 4D do not crash.

I registered this as a bug ACI0064077.

Empty PDFs with 'SET PRINT OPTION (9;3;$docname)'

2009-11-26T10:55:04Z

Dear colleagues

Can anyone see any major problem with this code as I have been staring at it for some time? The invoice appears following the launch external process command, but afterwards has a size of zero and cannot be re-opened! The folder is read-write. All other printing to PDF is via 4D Write and is not form bases and is working perfectly. I feel I am missing something obvious.

OUTPUT FORM([Lets];"SummaryInvoice")
SET PRINT OPTION(9;3;$document_name_path)
PRINT RECORD([Lets];*)
OUTPUT FORM([Lets];"Output")

C_TEXT($newpath)
$newpath:="/Volumes/"+Replace string(document_name_path;":";"/")
LAUNCH EXTERNAL PROCESS("open "+CHAR(Double quote)+$newpath+CHAR(Double quote))

Any ideas gratefully received.

11.5 change in behavior of SET DATABASE PARAMETER?

2009-11-26T09:41:43Z

I just installed 11.5, ran my unit tests (UnitTester), and found a change in behavior to the SET DATABASE PARAMETER([table]; Table sequence number; newSequenceNumber) command. It appears to cause the sequence number to be set to one less than what would happen in 11.4. For example, if you called SET DATABASE PARAMETER and set the sequence number to 5, in 11.4 it would have caused the next sequence number to be 6. In 11.5 it causes the next sequence number to be 5. Haven't figured out if this is a bug fix or a new bug. Will report back when I find out. But how cool is it that I can run my set of tests in 11.4 and they all pass, then run them in 11.5 and see a failure? All of this took less than a minute. This is protection against upgrades that may break your code! By the way, this is the only new failure I have in any of my unit tests.

Re: 4D v11 Component Architecture

2009-11-26T09:33:28Z

I would agree with everything David said (not just because of his nice statement about my ideas ;)). I think components are great for both development tools and modularizing production code. I have some thoughts on both...

Development Tools
Disclaimer: I have a commercially available development tool written as a 4D component ( http://www.unittester4d.com ). The 4D Pop set of developer tools are all simply 4D components that abide by some basic 4D Pop rules to make them all work with the 4D Pop palette. I love development tools (who doesn't?), and am happy to see that components can act as a sort of plugin to the 4D IDE. As David said, components can provide you with help in development (quality assurance is what my tool provides) that can be stripped away from the actual production release (so long as you keep calls to the tool methods out of production code).

Production Code Modularization
I have a couple of components that my clients use - namely a Utilities component and an ACH component. My Utilities component plays several roles.
* First, it is a sort of library of utility methods (as probably most of you already have your own utilities).
* Second, it contains a data viewer framework (an iTunes-like browser that allows for easy custom view generation).
* Third, there are several tools built in that allow my clients' applications to communicate directly with my company's application via SOAP.

You may wonder, why, if you are trying to modularize with components, would you write one that does several different things?

Well, originally I had a separate component for each set of closely related methods and GUI modules - trying hard to be strictly modular. So, my Utilities component was originally something like 5 different components. However, I found that startup time of the database was much slower with the more components I had. This makes sense, since each component has its own namespace I imagine 4D is having to set up a separate runtime environment for each component, which may also be using up more resources than you need (I don't know about this, just a guess).
Another drawback that I found was that if you have clients connecting over WAN, each time a component is updated, the entire component will be re-downloaded by the client. With 5 components, even though they were fairly small, this was taking way too long to be acceptable while development was fairly active (frequent updates).

So, the lesson is that there is a trade-off if you want to modularize using components. I love components, simply because I can make a change in my Utilities component and drop it into all my client installations (instead of having to open each client app structure file and make the same updates in each). But of course you must unit test so that when you drop a newly updated component into a client's application, you can hit a button and be sure that it didn't break anything ;-)

Hope this helps,

Mark

Re: 4D v11.5 Installer Error - Windows Server 2003

2009-11-26T09:15:49Z

Looks like this box has a policy set to require a digital signature on all
installers. Is the 4D installer signed?

If not, maybe you could disable this particular policy or add an exception.
Or, just copy the 4D Server files over after installing on another machine.

Sequence Number 4D Command Appears to be Broken in v11.5

2009-11-26T06:49:17Z

Dear All,

Hi. Just a heads up for everyone - further to the issue with Sequence Number
being broken in v11.4, I'm _extremely_ disappointed to report that it is
_still_ broken in v11.5. I was lead to believe that this bug had been
addressed in one of the 11.4 Hot Fixes but it seems that it didn't make into
11.5 final or maybe it was broken again somewhere along the way.

I would be interested to hear confirmation or otherwise from other 4D
developers whether they have found the same or not.

I have logged it as a bug and await confirmation from 4D.

Regards,

Narinder.

Testing 'locked' status without locking the record

2009-11-26T03:18:50Z

Hi Folks

A 'back to basics' issue I've come across and wanted to solicit
people's understanding of the 'LOCKED ATTRIBUTES' command.

Can I test for a record being locked (by another user) using this
command without actually locking it on the current client ?

In the past I've always used READ WRITE -> LOAD RECORD -> and 'locked'
for this since the only reason I needed to do this was to manage
regular concurrency. Now I have a need to test the 'locked' status of
a record without actually locking it - i.e. check the locked status
while the record is in READ ONLY mode.

Is it other peoples understanding of LOCKED ATTRIBUTES that you can do
this using this command ? The (2004) docs aren't specific about this.

4D v2004

Regards

Peter

Re: 4D v11 Component Architecture

2009-11-26T02:39:30Z

Walt

I've been using components to do simple stuff since they became
available in v11. I would not say I'm an expert at them by any means,
but here's what I've discovered.

1. Components more than ever force you to work with an API-type
programming model. I like this, but it's not everyone's cup of tea,
because it requires a lot of thought up front and very careful
execution; not so great if you're constantly modifying the component.
An API is especially important if the component has to access data
within the main program, because the component might find itself
working with only a subset of the tables in the database, or only a
subset of the fields in a table. So you'll need to decide how to
manage that interaction. Does the component get field and table
pointers by looking for known fields and tables in the structure? Does
it simply use SQL for its queries instead? Or does it add its own
"interface" tables to the structure when it starts up, and then let
the main program take care of how to get data into the main tables? I
can't tell you which of these options will work the best, but they
should all work.

2. For the type of usage you are planning, especially if the pieces of
your puzzle are relatively stable, components are a really great fit.
They're not so great for multi-developer scenarios where all the
developers are on one site and have to share either components
(because they're developing single-user) or a server (developing on 4D
Server). Basically, a component can only be opened once, which means
that you can't have two 4D single-user developers sharing a component.
You can't open a host in one copy of 4D (which loads all its
components too) and then open the component to edit it, which is
another thing that seemed logical to me. It's a pity that 4D has
imposed this only-open-once limitation, because these two scenarios
are examples of where components would have been really handy.

3. Components are also great for "temporary" functionality. Unit Tests
spring to mind (see Mark Schaake's great ideas for some food for
thought). Here it makes sense to test the different parts of your
program, but you don't necessarily want what's actually debug code to
end up in the production database. Put the debug stuff in a component,
and remove the component from the production build. Just make sure
your production code adjusts for the presence or absence of the debug
code if it needs to.

4. Components are also great for "supplementary" functionality,
perhaps some add-on modules that your customers don't want to pay for
up front, or for which you've promised the features but haven't yet
delivered. When the features become available or the customer coughs
up the cash, you send over the component and the host can take
advantage of all those shiny features in the component.

Others can chime in now - I've got to go do some washing up! :)
