http://blog.linuxmint.com/?p=3038#comment-130897
Several errors with Gambas3 version 3.8.4 as installed by Linux Mint 18 
Beta Synaptics Package Manager.
Note that I am running Gambas3 version 3.8.4 on Linux Mint 17 without 
these errors.

It does load and run but specific projects will not, which means this is 
going to be a bear to trace down the problems. I just happen to have a 
program that I use to record OTA (Over The Air) TV programs (I am too 
cheap to pay for cable). When I try to load this project I get lots of 
errors. The first of these are the missing modules: gb.qt4 and gb.qt4.ext

Well gambas3 has some new modules gb.qt5 and gb.qt5.ext
Problem is I can not get to the point of changing the required modules 
because I get another error in the IDE: 
“CDocumentation.ImplementAndNeed.1138”

This seems to be tied to a Gababas3 problem with the Offline Help system 
that was reported back in April:

[Gambas-user] CDocumentation.ImplementAndNeed.1138

[Lewis Balentine]

I am testing Linux Mint 18 Beta.
It comes with Gambas version of 3.8.4
I tried to run my KWPVR program project (which I admit is somewhat dated).
I got a strange error in the IDE: "CDocumentation.ImplementAndNeed.1138"
At this point I am only trying to determine if this is a Mint 18 or 
Gambas error.

Re: [Gambas-user] Issue 612 in gambas: BUG Cannot browse more of 128 records on tables "No current connection"

[Lewis Balentine]

My real point was (and I probably stated it very badly) is there is 
nothing in SQL that requires a table to have a primary key defined. Thus 
one should not assume such key exist unless it is a known DB structure. 
For a known structure there is probably an alternative aproach (orber by 
something, something ... etc). For an unknown DB structure the problem 
is more challenging. There may not be a "universal" way to produce a 
"rowid" on the fly but rather one for each particular SQL incarnation 
... and it should go without saying that such generated rowid's are ONLY 
valid for the subject query.

MySQL reference (using variables):
http://blog.sqlauthority.com/2014/03/08/mysql-generating-row-number-for-each-row-using-variable/

PostgreSQL reference (using supplemental view based on row_number()):
http://linfiniti.com/2011/11/adding-a-counter-to-postgresql-query-results/
http://www.postgresql.org/docs/8.4/interactive/functions-window.html

My apologies for being so aggressive/hostile/reactive.
It is just I have heard too many times that SQL tables must have primary 
keys ... and it just is not true.

Re: [Gambas-user] Issue 612 in gambas: BUG Cannot browse more of 128 records on tables "No current connection"

[Lewis Balentine]

SQLite (at least the current versions) will always have a row number: 
"/SELECT/rowid  FROM ..."

If the system does not have a unique row number built it (the only thing 
that I use these days is SQLite) then it should be able to be generated 
"on the fly" using a calculated field along with the query. There have 
been many, many DataBases built that do not have key fields defined. One 
particular major accounting system comes to mind that was my curse to 
deal with for many years.  It has been so long since I have encountered 
anything that does not have a row number that I can not recall the SQL 
code to get around it I will continue searching :'(

There is NO valid SQL reason why a table should be required to have a 
unique primary key or any predefined key for that matter. One can always 
use the row number (record number) if such a key is required for one's 
application.

Re: [Gambas-user] Strange problem with windows/postgresql/form.db

[Lewis Balentine]

When you have time can you post exactly what you did to compile in the 
windows/cygwin environment ?
Such things as 32 or 64 bit?
What did you do for all the external libraries ?
Are there any errors in the make/compile/install logs ?

Very Best Regards,

Lewis

Re: [Gambas-user] Issue 616 in gambas: Where do files get installed or downloaded to from software farm

[Lewis Balentine]

In any scenario the two subjects most likely to start an argument are:
1) religion
2) politics
(in some case it may be the same subject).

There is an old story about a scorpion riding across a pond on the back 
of the frog. Half way across the pond the scorpion stings the frog.
The frog asks: "Why did you do that? We are both going to die now."
The scorpion response, "I am a scorpion. It is what I do."

I seriously doubt that there is any country in the world with a 
functioning government that does not have spies in their employ.

Re: [Gambas-user] Issue 616 in gambas: Where do files get installed or downloaded to from software farm

[Lewis Balentine]

Perhaps an alternative suggestion (compromise):

An application written in Gambas to manage Gambas project/example files.
I am thinking something with two windows: Source and Target
The app would dynamically build the path to the hiddden source directories.
The user could pick the target directories
 of course one would be free to add "enhancements" to that scheme. ;-)

Cheers,

Lewis

My main workstation gets its Gambas from the PPA.

In 'update manager' is listed as:

3.7.0-24.30~ubuntu14.01

(I assume this is related to the same issue , but I could be wrong).

Re: [Gambas-user] URGENT request to people of Gambas stable PPA

[Lewis Balentine]

Another alternative:

You might use 'apt-get' and 'apt-cache' (on a clean machine) to:
1) download Gambas 3.6.2 from the current PPA
2) build list of dependences
3) download all dependences

Then copy all the debs to an appropriate portable device (USB Drive)
Then write script to:
1) Install dependences first with web disconnected
2) Install Gambas 3.6.2 second with web disconnected
3) Install your custom application(s)

I use a similar method to install Linux on a new machine so it can not 
download during the installation before I have a chance to point it 
toward my local "apt-catcher-ng" cache (much faster and saves a huge 
amount of bandwidth).

I think that you are probably be better severed by a local repository 
but it it never hurts to have a plan "B".  ;-)

cheers,

Lewis

Have you considered setting up a local PPA.
In that way you might also control 'what else' gets updated.

Re: [Gambas-user] Release of Gambas 3.7, error in build

"libdumb.so.1"

Well I found two possibilities:
libdumb1-dev: libdumb1 (dynamic universal music bibliotheque)
libdumbnet-dev: libdumbnet1 (libdumbnet is known as libdnet in other 
distributions)

As OpenAL (Open Audio Library) is a cross-platform audio API I decide to 
give libdumb1 a try.
sudo apt-get install libdumb1-dev

That has eliminated the errors in the "makeinstall.log".

Cheers,

Lewis

Qu'est-ce  bibliotheque ?

serbatoio voi Gianluigi,

You saved me a lot of time. I did however find one more package that was 
required.

# || Unable to met pkg-config requirement: QtOpenGL
# || gb.qt4.opengl is disabled
# add libqt4-opengl-dev
sudo apt-get install libqt4-opengl-dev

I also added the log files as you illustrated.
Thus I got all the way through "./reconf-all" and "./configure -C" 
without any problems.

At the end of the configure-C.log file I found the Magic Words:
"ALL COMPONENTS WILL BE COMPILED"

I was also able to get through "make" and "make install". These two 
generated a great number of warnings however the required executable 
files were produced and gambas3 runs as expected. I tested it on two 
simple projects. One console base and one GTK gui. Gambas appeared to 
operate as expected.

Benoit,
I do not know if this will be helpful but regarding the warnings/errors:
Please see attached archive file for the make logs as well as the errors 
captured from the console.


For "make" they were typically warnings about depreciated calls for GTK.
---make example
gtools.cpp: In function 'gColor get_gdk_bg_color(GtkWidget*, bool)':
gtools.cpp:179:5: warning: 'GtkStyle* gtk_widget_get_style(GtkWidget*)' 
is deprecated (declared at 
/usr/include/gtk-3.0/gtk/deprecated/gtkstyle.h:672): Use 
'gtk_widget_get_style_context' instead [-Wdeprecated-declarations]

  st=gtk_widget_get_style(wid);
 ^

For "make install" they were typically errors about missing 
"libdumb.so.1" file.

---make install example
make  install-data-hook
make[4]: Entering directory 
`/home/gbuilder/Documents/Build/gambas3-3.7.0/gb.openal/src'

Installing the gb.openal control icons if needed...
Creating the information files for gb.openal component...
Error loading libdumb.so.1: libdumb.so.1: cannot open shared object 
file: No such file or directory


For "make install" they were typically errors about GTK_IS_WIDGET.
---run time error example
(gbr3:1151): Gtk-CRITICAL **: IA__gtk_widget_get_direction: assertion 
'GTK_IS_WIDGET (widget)' failed


Last and most importantly:
Thank you very much Bennoit for Gambas, your time, your dedication and 
most all your continuing support.


Regards,

Lewis Balentine

Re: [Gambas-user] Release of Gambas 3.7, error in build

[Lewis Balentine]

Regarding Linux Mint 17.1 (a.k.a. Rebecca):
Becky had some teething problems and added a bunch off fancy user 
interface graphics that I did not need or want. Thus I decided to stick 
with 17.0 (updated of course --- so I may have all that stuff I did not 
want).




Strange, as I successfully compiled and installed the development version

on Mint 17.1 a few weeks ago.<
--
I install version 3.6.2 from the ppa. My abilities with 'C', 'C++', 'C#', gcc , 
g++, make, gbd, etc. are very limited. They are getting better. I am now 
capable of compiling the following 'C' program:
int main(){};
... and I am working on helloworld.c

So I created a fresh VMWware virtual machine for build Gambas. It is based on 
an OVF image of Linux Mint X64(OEM) with Mate desktop that I maintain for such 
things. That gives me a more less 'virgin' environment with new machine name, 
user name and password. I get the same errors on that machine as well. (I now 
have an backup OVF image of a 'virgin' GambasBuild machine as well ;-) The Idea 
is that I can create new machine, extract the new source to it and run the 
shell script (see attached) to build a new version (when I get it working).
===

Progress:

1) commenting AC_LIBLTDL_CONVENIENCE in the 'acinclude.m4' file resolved the 
"./reconf-all" error.
   (note: has to be done BEFORE the FIRST attempt to build gambas)
2) several errors produced by "make" because Mint does not install g++ by 
default (resolved)
3) "sudo make install" produces the following errors:
--
libtool: install: /usr/bin/install -c .libs/gb.image.effect.so.0.0.0 
/usr/lib/gambas3/gb.image.effect.so.0.0.0

I am guessing the the "libs" (not the 's') directory is actually 
"~/Documents/Build/gambas3-3.7.0/main/lib/image.effect/.libs"
There are two directory entries there listed as as "link broken 
(inode/symlink)":
  gb.image.effect.so
  gb.image.effect.so.0
So I went looking to see if there were any other "broken links" ...
  ~/Documents/Build/gambas3-3.7.0/main/lib/clipper/.libs/gb.clipper.so
  ~/Documents/Build/gambas3-3.7.0/main/lib/clipper/.libs/gb.clipper.so.0


Just to be sure this was not a fluke.
I replaced the image and tried again ...
second time around I got different errors;
among them are:

Re: [Gambas-user] Release of Gambas 3.7, error in build

[Lewis Balentine]

I was just checking that ...

Ref: http://gambas.sourceforge.net/en/main.html
The following versions of GNU tools are needed:
automake 1.11.1
autoconf 2.68
libtool 2.4
Compiling with older version may or may not work!
-
$ automake --version
automake (GNU automake) 1.14.1

$ autoconf --version
autoconf (GNU Autoconf) 2.69

$ libtool --version
libtool (GNU libtool) 2.4.2
-
I think i found it in the source files:
Reference: acinclude.m4, line 148

I think that I found something about this error as well (not that I 
understand it):
reference:

http://www.gnu.org/software/libtool/manual/html_node/Distributing-libltdl.html
Macro: LTDL_CONVENIENCE
Macro: AC_LIBLTDL_CONVENIENCE
These macros are deprecated, the ‘convenience’ option to LTDL_INIT 
should be used instead.

 >> Email's still in the frakking DARPANET ages. <<

I tend to agree with you. However getting the entire world's electronic 
population to change would a daunting challenge. Perhaps if one was very 
dedicated, aggressive with unlimited resources it could be accomplished 
after a suitable period of time (maybe a decade or so). In the interim 
period we must learn to work with what we have at hand.

Re: [Gambas-user] A couple of questions about building web / cgi applications

[Lewis Balentine]

Forgive me for poking my nose in where my profound ignorance indicates I 
should not but 

Would not a direct solution be:
1) Have the resident program ALLOC a section of ram
2) Save the address as part of a unique file name (i.e. ADRxx.ADR 
where x is the address)
3) Pass the required parameters back and forth via shared memory.
4) Both programs would need to poll the shared memory for updates (some 
bytes could be used for status).

Well when you get past that ...

I created a new VM as well (Vmware). This time I did not check the box 
'save password'.
Then when I tried to publish the project I got the following error:
"Unable to publish project.
  Incorrect version

... but it seems to have gotten published anyway. :-)
The screenshot is 3X larger than the rest of project ...

[Gambas-user] Data Base Example

[Lewis Balentine]

Following a thread from last week regarding refreshing DataControl I 
have developed a small GUI project to demonstrate the use of DataSource 
and DataControl items of gb.db.form. It demonstrates how to create the 
data connection, move between records (first, previous, next, last), 
save/cancel edits, begin/commit/rollback transactions.  There are 299 
lines of code with the majority dedicated to enabling/disabling the 
various buttons. It includes a SQLite data file but should be compatable 
with any supported Database.


I did "try" to publish this to the software farm but I encountered a 
problem with my credentials. Comments or suggestions for improvement are

Re: [Gambas-user] Software Farm, Unable to get password.

[Lewis Balentine]

It is  'gnome-keyring'. It is installed and as far as I know not 
disabled. I am not having any trouble with it --- well not until now 
anyway. I believe Chrome uses it as well. I opened TitanTV web site in 
Chrome to verify that it was able to use 'saved' credentials for that site.

Re: [Gambas-user] DataControl_Leave, Tab key causes Gtk - CRITICAL Error

[Lewis Balentine]

I switched the desktop QT Style back to 'GTK+' and changed the project 
to from gb.qt4 to gb.gtk (and gb.gtk3).
I get no error but I get no functionality either :-(

The Tab keys goes through the next three controls without setting the focus.
Those controls are:
 DataControl3 (date: switch from date string to calendar)
 DataControl4 (boolean)
 ButtonNext (standard form button)

I closed the project and switch the Desktop back to QT Style back to 
'Windows'.
There was no change.
Then I tried gb.gui  no change (Both QT Styles).

Just to be thourogh I tested it with QT Style 'Plastique' as well.
This was the same results as 'Windows'.

I think I have gone through most of the possible combinations ... :-)
What does work as expected is: QT Style = 'Windows' or 'Plastique' with 
gb.qt

Lewis

I changed the 'QT GUI style' to "Windows". The problem went away. So the 
problem is probably in the 'GTK+' style which I believe is the default for 
Mate. I will post this thread to the Mint forumns and see if there is any

Re: [Gambas-user] DataControl_Leave, Tab key causes Gtk - CRITICAL Error

[Lewis Balentine]

Note the project  is a QT graphical project as opposed to a GTK 
graphical project (if it makes any difference).

As for GTK+ theme  how would I know ? I am using Linux Mint 17 with 
the Mate Desktop environment. There are no preferences that refer to 
'GTK theme' but my 'appearance' preferences are set to "Mint-X" theme. 
That is the only reference to a 'theme' that I can find in the OS.

I had some previous problems with QT themes (no frame borders). QT GUI 
style is set to 'GTK+'. The other choices are (how can I say this 
politely???) unappealing.

Lewis

Yep that seems to work. I did try that previously (I think) but it seems

Overall it has been a very enlightening exercise. Now what was I doing 
before I started this ?

I believe that you need to define the connection host (path to Sqlite DB 
file).
 hconn.host = Application.Path

Otherwise I get the same results.

Re: [Gambas-user] Use of db.Begin, db.Commit and db.Rollback with a datasource and datacontrols

[Lewis Balentine]

Nope, you did not mislead me 

I was already been looking at these methods, but I had only tried the 
update function on a dataview control where the data was modified by an 
external program (that works nicely).

I believe that I have tried every combination of: DataSource.Cancel, 
DataSource1.Update, DataSource1.Refresh

BINGO!!
Put "DataSource.Connection.begin" just after the DB/Table is opened.
Put "DataSource.Connection.commit" and "DataSource.Connection.begin" at 
the end of each save.
Use  "DataSource.Connection.Rollback", "DataSource.Update", 
"DataSource.Connection.Begin" to cancel.

Alas I have run out of time and must attend to other matters.
I will try update my example tomorrow and upload it.
(I also want a bit more testing).

Regards,

Lewis

Re: [Gambas-user] Use of db.Begin, db.Commit and db.Rollback with a datasource and datacontrols

[Lewis Balentine]

Mr. Speaker,
I request permission to revise and extend my previous remarks ...

Please see the attached sample application and data base. I used a 
SQlite Database but in theory these function should operate the same. I 
tried five ways to cancel the edits to a set of data controls.

via Control Refresh
via Data Source Refresh
via Data Source Cancel
via Closing the DB and reopening it
via Data Control Tags

The only one that I found that worked was to restore the content from a 
copy saved in the data control tags. I note that changing the 
'DataControl.Value' (either via software or manually) does not set 
'DataSource.Modified' or "DataControl.Modified' properties to true. The 
operation was the same in version 3.6.2 and 3.6.9.


Then again maybe I am doing something(s) wrong  :-\

Regards,

Lewis Balentine

Hello Martin,

If you are working with only one record at a time, you don't need to use 
transactions.
Transactions are used when multiple records need to be modified in an all-or-none 
scenario, such as when a record, that is the "one" in a
one-to-many relationship, needs to be deleted.

In such a case, you would start a transaction with .Begin, delete the dependent 
records followed by the one record. Then, if all modifications
are successful, you would .Commit. If there is a failure at any time during the 
transaction, you would .Rollback.

To get the datacontrol to display the original data after a canceled edit, use 
the .Refresh method.

Re: [Gambas-user] Use of db.Begin, db.Commit and db.Rollback with a datasource and datacontrols

[Lewis Balentine]

 >> use the .Refresh method <<

That assumes that one is using data linked controls. That is not always 
the case:
examples:
  a date record is displayed/edited  as two separate text boxes 
(i.e. date and time)
  a person's name is stored in the fields: given_name, initial, 
family_name
  the person's name is displayed/edited in a single text box

I have in the past (with VB6) used the control.tag property to hold the 
original unedited text for the control. I have also been known to use 
that information to verify another user had not changed the original 
record prior to processing the update.

You were correct (as usual). :-)

There was an difference in the dynamically generated ffmpeg command 
arrays that I was using. The application is now functional so I can 
start working on the fine tunning and polish.

Thank you for your help.

Re: [Gambas-user] need NOWAIT option for Process=Exec Command

[Lewis Balentine]

I inserted the following line before my Exec statement:
   Debug Format(Now, "hh:mm:ss")
   MyProcess = Exec ["sleep", "10"]
   Debug Format(Now, "hh:mm:ss")
   Debug "PID:" & Trim(Str(MyProcess.Handle))

It worked as you said
  pvr.StartProcess.99: 14:01:57
  pvr.StartProcess.101: 14:01:57
  pvr.StartProcess.102: PID:17978

Guess that I will have to dig a bit deeper. The ffmpeg application 
accepts input while recording. I wonder if that has some effect on the 
matter.

Cheers,

Lewis

HDHR4-2US).  If I use the GAMBAS statement:
Exec Command
then the ffmpeg command is executed and the recording takes place in the 
background as desired.


My problem is that I need to get the Process ID for each recording 
session in order to be able to abort/cancel recording session(s). If I 
use the GAMBAS statement:
Process = Exec Command
then the program hangs up while it "waits" for the Command to complete 
(which might be a couple of hours).

Now I am hung up. Is there another way to get the process id?

cheers,

Lewis Balentine

Thank you ... but just in case someone else find this in a search:

I believe that you intended: qtconfig-qt4 (an application that must be 
installed on the current system)
"GTK+" seems to be the only one where the frame border does not show up.

[Gambas-user] QT Frame, no border

[Lewis Balentine]

Frame (gb.qt4)
"This control is a container with an *etched border* and a label. The 
actual appearance of the frame depends on the underlying widget theme. 
Some of them do not even draw any frame at all!"


I am getting no border. I see no obvious way to get to the 'underlying 
widget theme'.

So what is it that I need to fix ??

Lewis

You and the other members of the mailing list have been very patient, 
tolerant and helpful. Version 1 is a text file based Gambas console app 
and is currently serving the immediate need. I am working on version 2 
that is database driven with a GUI interface. I think that I shall 
reserve fine-tuning the Data-Manager for version 3 or 4.

Re: [Gambas-user] Column Alignment Property

[Lewis Balentine]

My application is sort of a mini-datamanager where the end user 
determine which tables/fields they need/want to access. The application 
generates the datasources and dataviews at run time. Each table is 
displayed in its own tab of a Tabstrip /(small screen shot attached)/. 
There are two tables in the DB that hold the parameters for the run-time 
tabs.


My OOP competency level is marginal :-[
I am actually amazed that I have made as much progress with this as I have.

*Correct me if I am wrong: *
The event handler would have to be created at design time.
Thus I would need to create a new control class that inherits dataview.

Lewis

The DataView control (normally) raises a Data event for each cell it draws.

In the event handler, you can use the DataView.Data property to modifiy
the contents of the cell just before it is drawn, exactly like the Data
event of the TableView control.

Then you can change how the cell value is drawn, the alignment, the
colors...

[Gambas-user] Order By Clause

[Lewis Balentine]

Is there any way to sneak an "order by" clause into a Datasource or 
Dataview.

I did try putting a complete SQL statement in place of the Table name 
but that results in a read-only result regardless of the value of the 
Datasource.ReadOnly property.

I know I can set the Sort poperty true to allow resorting by a 
particular column but I would like to have control of initial order by a 
combination of columns (i.e "order by StartDateTime, Channel, Status").

Lewis Balentine

Re: [Gambas-user] Column Alignment Property

[Lewis Balentine]

I changed my Integers to Longs and set limits on the length of most of 
the strings.
I do have a suggestion if you get around to working on this:
add a property to the columns to hold a format$

examples:
 Dataview.View.Columns[?].Format="mm/dd/"
 Dataview.View.Columns[?].Format="dd mmm "

This would be handy particularly where a date is stored with no real 
time portion.
Dates are displayed as: mm/dd/ hh:nn:ss
Example:
 21 January 2015 displays as 01/21/2015 00:00:00

There are probably other circumstances where it would be useful.

Now someone is going to tell me that capability has already implemented 
and I have missed  reading the proper link again. :-)

Lewis

[Lewis Balentine]

Result (gb.db)
This class represents the result of a SQL request.
This class is not creatable.
This class acts like a read / write array.
This class is *enumerable* with the FOR EACH keyword.

Guess this should be obvious but not to me  pray tell what 
type/class does one use to enumerate it ??
I tried "ResultField[]"
I tried "Collection"
I tried to try "record"
As a last resort I tried String[]
Suffice it to say: I have not a clue :-\

Dim MyRecord as ?

Result = Connection.Find (Something)

For Each MyRecord in MyResult
 Print MyRecord["Field1Name"]
Print MyRecord["Field2Name"]

Next

Thank you for the clarification.

Maybe I should create a property that would tell DataView if it should override

That would be most helpful. :-)

Re: [Gambas-user] Array.Sort

I did not expect this many comments. I believe that the KISS principle 
should apply to the Wiki particularly for the benefit of new users or 
those whose first language may not be English (my British friends tell 
me that English is not my first language). I removed references to 
"procedure" and "function".

 ' The empty set of parentheses is REQUIRED when sort is called
 ' without the optional mode parameter and is expected to return
 ' an array.

 ' The empty set of parentheses is NOT required to sort the array
 ' without returning anything.

 ' all three examples print the following:
 1234567890
 ABCDEFGHIJ
 abcdefghij

[Gambas-user] Column Alignment Property

[Lewis Balentine]

It appears to me that the Column Alignment Property does not work for 
some types.


 Sample Code: 
Public Sub ButtonCenter_Click()
  Dim I As Integer
  For I = 0 To DataView1.View.Columns.Max
DataView1.View.Columns[I].Alignment = Align.Center
  Next
  Me.Caption = Application.Name & ": Center"
End
-
The results are:
Serial, Boolean, Long, Date: Column Alignment as expected
Integer, Float: always Align.Right
String: always Align.Left

Please see that attached project archive for source code and otherwise 
useless SQLite3 Database.


On another note:
I wanted to verify these results with a later verions of GAMBAS. I have 
one machien set up with: deb 
http://ppa.launchpad.net/gambas-team/gambas-daily/ubuntu trusty main. It 
reported version 3.6.99 available. I did the normal update but it still 
reported 3.6.90.


I then did: $ sudo apt-get purge gambas3
followed by: $ sudo apt-get autoremove
followed by: reboot
followed by: sudo apt-get install gambas3

It still reports version 3.6.90 although as I watched the install I 
clearly saw references to 3.6.99 (see below).

... and the results were the same for all three version tests.

Lewis Balentine

--- you got me on that one

In GAMBAS there seem to be several class methods defined that sometimes 
require parenthesis and sometimes do not. I was trying to 
determine/define the conditions that delimit when those parenthesis are 
required using familiar BASIC terms ... as in:
 Public/Private Function  foo () as data type
 Public/Private Sub  foo ()
both of which I believe are appropriately considered methods in OOP 
languages.

I believe my second formal computer class was MBASIC on a Osborn CPM 
computer (4 inch green screen). I am trying to recall if the term 
"Function" was defined in that language but those gray cells are no 
longer responding reliably. The other option was "Go to" that eventually 
evolved into "Public/Private Sub". At the time we called those 
"procedures".  I still call them "procedures" to distinguish them from a 
"function" that by definition is supposed to return something.

Take a look at what I put in the WiKi and let me know if I should change it.
http://gambaswiki.org/wiki/comp/gb/string[]/sort
... and if someone insists I will go back and change the variables to 
Hungarian notation but personally I find it more confusing than enlighting.

[Gambas-user] Array.Sort

[Lewis Balentine]

I was playing around trying to learn how to pass string arrays back and 
forth.
I then looked at the array.sort function. The prototype in the Wiki 
indicates that it returns an "string[]".

   Function Sort([Mode As Integer]) As String[]

However it seems that I can not use the returned values(s) where I would 
normally use an array. It appears to to me to operate more as a SUB than 
a FUNCTION in that it resorts the array but does not return something 
that I can use in another function or procedure. Is my interpretation of 
the prototype wrong-headed ?

Regards,

Lewis Balentine

Re: [Gambas-user] Connecting DataControl to DataSource

[Lewis Balentine]

YEP --- that was the problem. I completely missed "is a container". In 
MS VB5/6 you only needed to place the Datasources on the same form  
actually not even that: you could build a connection or selection set 
and reference that.

One thing I would like to see is the ability to return the SQL Query 
actually used to obtain the "Result". This would be very helpful when 
trying to figure out why something did not work like one expected it to. 
I have used the "Subst" function to build such a string but there is 
always the nagging doubt that it is not exactly the same via some way 
Gambas handles substitutions or (more likely) I made a typo in 
duplicating the process.

Thanks for you help LEE.

Regards,

Lewis

[Gambas-user] Connecting DataControl to DataSource

[Lewis Balentine]

I must be missing something very basic in the use of form database controls.
I can not seem to get a data control populated ...
It appears to me that the data control is not linked to the DataSource.
What am I missing ???

Two additional questions:
Is there a way to access the "Result" object of a DataSource ?
Is there a way to change the "DataSource" for a DataControl ?

Re: [Gambas-user] Wiki Observation, SQL syntax

[Lewis Balentine]

 >> where to put the missing information? <<

Did I mention before that my ignorance is eminence ?   :>)
Well I am also a senile old goat: There is a mention of how syntax for 
arrays is a bit different in Gambas, but I do not seem to be finding it 
today  oh there it is under Array Declaration (ref: 
http://gambaswiki.org/wiki/cat/arraydecl). I thought perhaps a link on 
this page would be good as well but perhaps not as it is more oriented 
toward numeric indexed arrays.

I really thing that there needs to be a good section on using the GD.DB 
components (someone started this with "How to create and use MySQL 
connection").

I think that I should refrain from making a suggestion in this regard as 
I am still working at understanding the general Lexicon and Syntax 
conventions used in Gambas. One of the things that made VB5 so popular 
was its excellent help system. In VB6 MS dumped in everything else from 
their array of languages and tools (that did more damage than good). 
Gambas is well on its way to having a good help system (I would like to 
see a Gambas Wiki search function, but there is always Google). I hope 
to be able to contribute to this effort in the future --- perhaps by 
adding examples.

Regards,

Lewis Balentine

Re: [Gambas-user] Wiki Observation, SQL syntax

[Lewis Balentine]

Thank you to both Benoit and Tobias for the explanations. I did figure 
it out but did not realize that a "Result" could be treated as an array. 
I tend to think of DB data as structures.

... but my real point was that when the syntax can be considered a bit 
unusual then the Wiki needs to document the use of the syntax. Otherwise 
potential new users are left without a clue. I observed this case and 
thought that it was perhaps worth mentioning so someone might at 
sometime update the information.

Cheers,

Lewis

[Gambas-user] Wiki Observation, SQL syntax

[Lewis Balentine]

For some reason I do not seem to be able to log into the Gambas Wiki. 
That is probably a good thing considering my level of ignorance (which 
has proven to be immense). Thus I pass these observations along for 
consideration:

I have dealt with various SQL Data Bases for some two decades (primarily 
Oracle but also MS SQL, Access, etc.). When I started looking at some of 
the Gambas functions I found a syntax pattern that I was unfamiliar with.

Ref: http://gambaswiki.org/wiki/comp/gb.db/_connection/find


Function *Find* ( _Table_ As String *[* , _Request_ As String, 
_Arguments_ As , ... *]* ) As Result 



  *

_Table_

  *

_Request_

  *

_Arguments_


I assume that this form comes from a language that I am unfamiliar with 
(or perhaps an implementation of stored procedures) and thus goggled: 
SQL Request Arguments
I found a few references to MS Excel but no suitable explanation. I 
finally found the answer in the "obsolete" Gambas Wiki that is still online:

Ref: http://gambasdoc.org/help/comp/gb.db/connection/subst?v3
Creates a SQL sentence by substituting its arguments into a format string.

  * _Format_is the SQL sentence.
  * _Arguments_are the arguments to substitute.

The&1,&2... patterns inside the_Format_string are replaced by the SQL 
representation of the 1st, 2nd..._Arguments_.

These arguments are quoted according to the underlying database SQL syntax.


I also note from an example in the "obsolete" Gambas Wiki that an 
explanation mark "!" is used to delimit field names in a result.
http://gambasdoc.org/help/comp/gb.db/connection/edit?v3

I do not find any similar example in the current Gambas Wiki but perhaps 
I missed it.

Regards,

Lewis

Re: [Gambas-user] IF Not (any boolean) then

[Lewis Balentine]

 >> The error is not the NOT it's the missing ()  <<
Actually the error turns out to be  "EXTRA" (Parenthesis).
The following two lines do not produce the error:

If Not True Then Print "False" Else Print "True"
If Not TestFunk() Then Print "False" Else Print "True"

It was my mistaken impresion that the parameters of an operator(s) could ALWAYS 
be enclosed within Parenthesis as in:

X = 1 + 1
X = (1) + (1)
X = (1 + 1) * 1

[Gambas-user] IF Not (any boolean) then

[Lewis Balentine]

If I use "NOT" in an "IF" statement with any boolean (function or value) 
then I get an error. example:

If NOT (BooleanFuntion) then Do this
unknown identifier: NOT

Am I mistaken in thinking that one should be able to use the NOT 
operator in this manner ?

I can get around this by changing the syntax to. example:
If BooleanFuntion = False then Do this

That is tad inconvenient for what I am trying to do. I want to write a console 
based application to process a number of files in the directory from which the 
application is run with no concept of what that directory might be at design 
time. I was going to use the 'cd' command to change to a target directory for 
development/testing --- then comment it out afterwards.

I think that can be used as an alternative solution to my problem.

Thank you Tobias.

[Gambas-user] File & Directory Functions: PWD, cd

[Lewis Balentine]

I can find out what the current directory is with:
 Print Application.Env["PWD"]

However there does not seem to be anything to change the present working 
directory within the "File & Directory Functions".
I did try using the shell function. It did not seem to have the desired 
effect.
   Print Application.Env["PWD"]
   Shell ("cd /mnt/Data/videos")
   Wait 0.1
   Print Application.Env["PWD"]
--
 /home/lewis
 /home/lewis

So I guess that I have missed something obvious again.
How does one change the current directory in a Gambas console based 
program ?

Thank you,

Lewis

[Gambas-user] What is the Gambas equivalent of Inkey ?

[Lewis Balentine]

For a console application I want to issue a prompt:
"Press any key to continue ..."
or
"Press 'X' to exit or 'C' to continue:"
and then wait for the user to press a key.

I can find no equivalent for the Basic "inkey" function. I have tried 
using wait/read but it seems one must press the "enter" key.
Private Function InKey(Prompt As String) As Byte
   Dim n As Byte
   If Prompt <> "" Then Print Prompt
   n = 0
   While n = 0
 Wait 0.01
 ' n = Read As Byte
 n = Read 1
   Wend
   Return n
End

Suggestions ?

Lewis

Re: [Gambas-user] Try not catching XmlDocument Error

[Lewis Balentine]

I can not. I assume that I would have to download, build/compile and 
install that particular or later version. I am just a month into the 
land of Linux and less than half of that into Gambas. I have not 
advanced that far yet (still on baby steps).

I worked around the problem. As of about 6 hours ago I have my first 
Gambas application running (if somewhat crudely).

Re: [Gambas-user] gb.settings comments deleted

[Lewis Balentine]

*.conf appears to be similar to *.ini files found for decades on the the 
ms windows platform. I have always preferred them in that environment 
rather than the newfangled and nearly unmanageable windows registry. 
They allow one to modify the operation of a program without having to go 
change the source code. It is handy to be able to modify these 
configuration files  with a plane text editor to meet requirements of a 
change in the environment (i.e. that critical shared network directory 
has been moved to another location). After number of years not touching 
a particular ini/conf file it may be useful to have a few comment in the 
file to refresh one memory cells. Another unusual feature of the conf 
files is that gb.setting reorders the order of the slots ... 
interestingly enough it maintains the order of the keys under the slots.

One needs to be adaptable. In the case in question I have inserted a few 
remarks as :
[0-kvpr]
remark0 = "all comment lines are stripped from this file by the application"
remark1 = "these directory paths must be terminated with a forward slash 
'/'."
...
[1-job control]
remark0 = "job 001 is a template, do not delete it."
...

Problem (at least mine) solved :-)

regards,

Lewis

[Gambas-user] gb.settings comments deleted

[Lewis Balentine]

When settings are written back to the ".conf" file all comments/remarks 
are stripped from the file.
Should not the documentation include a warning to this effect?
Better yet would be to keep those comments/remarks intact.

example incoming:
[slot]
; remark
# remark
; comment
Value0ne =1
ValueTwo =2
ValueThree =3
# end of file

example outgoing:
[slot]
Value0ne =1
ValueTwo =2
ValueThree =3

regards,

Lewis
