I can toggle Console and Notes normally without issue. I do not see any "Find

Hi list,

Is it possible to generate a QR code image from gambas?

Thanks

You could shell out to the 'qrencode' command-line utility.

Or, look on the Gambas Farm for "QRCreator".

Hello
Thank you

I guess because I'm translating through Google into English so I'm not well 
understood, I'm sorry.

I'm not talking about the bold text

I'm talking about, adding space character, and it spoils the HTML code

For example:
<%
Dim sEnv As String
%>



But if I lower the% at the end
For example:
<%
Dim sEnv As String



< html >
< / html >

Look, this adds a space character


Of course, this is not HTML anymore, but Gambas code.

But why do you want to remove the "%" in the first place, and then move
the cursor to another line?

Re: [Gambas-user] Format function changes date value

[T Lee Davidson]

CDate uses UTC and, without the time information in the string, it would store 
midnight. Format uses local time.

So, anyone in a time zone behind UTC will get the previous day printed. Try 
this format string:
zTestResult = Format(CDate(zTestDate), "mm/dd/yy hh:nn ddd")

Does the difference in hours match your timezone offset?

The gambas3-script sub-package provides /usr/bin/gbs3.gambas which is symlinked 
from /usr/bin/gbs3.

To verify that, on the software search page under Gambas3, click on "Show 101 Sub-Packages". Scroll down to the bottom and click 
"script". (I'm not sure why "scripter" is even listed.)


And, yes, this is in the Education repository. You can also try the Packman 
repository: http://packman.links2linux.de

You located the gb.gsl component files only. These files mentioned (gsl_cblas.h, gsl_math.h, libgslcblas.so, libgsl.so) are

Try "locate gsl_".

You may need to ensure the GSL development package is installed.

Yes, when you use --depth=1, you only retrieve the latest commit,

so

it

can't know
about anything past it.
If you want to have the information locally, you can use the

following :


git fetch --unshallow

It will retrieve the missing pieces and you will end up with a full

clone,

as if you just ran git clone without the --depth argument.

You can also view the latest commits directly on gitlab here :

https://gitlab.com/gambas/gambas/commits/master

… or as a RSS feed here :

https://gitlab.com/gambas/gambas/commits/master?format=atom

If you have a Gitlab account, you can also configure it so it will

send

you
email notifications when something happens on the repository.

The latter is sth I could do, as I already host gambas-club.de at my
hosting provider. As I can see the traffic the Gambas lists creates is
not a big problem.

But I'm in holliday right now.

Alles Gute

OK, thanks. I will wait for your return.

If anyone has ideas about how and where to host at least two mailing-lists, you 
are welcome!

Regards,



There may be reason to be concerned about the long-term reliability of freelists.org. They use three different free software 
packages, two of which haven't been updated in over three years and the third's website doesn't even load.


The Gambas community might be better served by setting up Mailman at something like list.gambaswiki.org as suggested; even 
though Mailman setup does not, at first glance, appear simple and would take an initial time investment.

I assume you mean that you need (not necessarily greater accuracy which is dependent upon the server, but) greater precision by

You may have hinted at the solution within your question. Have you considered 
using a Structure?

http://gambaswiki.org/wiki/lang/read :
"... reads the stream Stream as binary data whose type is specified by the Datatype 
argument."

"The returned datatype can be one of the following: NULL, Boolean, Byte, Short, Integer, Long, Pointer, Single, Float, Date, 
String, Variant, any Array, Collection or structure."

I don't know why you are trying to use Eof() on a SQL Result. Eof is for a 
Stream.

See:
http://gambaswiki.org/wiki/comp/gb.db/result

"This class is enumerable with the FOR EACH keyword."

And, I believe 'ListBox1.Add(Lresult!"name")' should be 
'ListBox1.Add(Lresult!name)' or 'ListBox1.Add(Lresult["name"])'.


Also, please try to compose meaningful subject lines by creating a _new_ 
message instead of simply replying to a message that is 
not related to your issue. That helps those who view list messages in threaded

Disable (ie. comment out) targetpw and the "ALL  ALL=(ALL) ALL" line in

Then you should probably allow regular users to execute only certain commands

or a special group for 'privileged' users:
%wheel  ALL=/home/adminuser/bin/comando.sh

Thank you for your response, Tobi.

I was actually running the application from within the IDE. Making an 
executable and then executing that with "gbx3 -g" resulted in:
Welcome to the Gambas debugger.
*[15488]?

followed by the greater-than symbol () which is obviously an input prompt. 
"OK, now what?" (Since I find no documentation 
for gbx3.)

Typing "help" at the prompt gave, "W   Unknown command: help". Hmmm ... 
maybe "step"? Ooo, that does something:

 step
*[15488]Main.Main.7 sName   S: s:
 step
*[15488]Main.Main.8 sName   S: s: 

 step
15488 

*[15488]Main.Main.9 sName   S: s: 

 step
*[15488]Unable to open fifo Main.Main.9 sName   S: s:

And I discovered that there is a "quit" command that works too.

Given that Debug.Begin creates pipe files named according to the current 
process' ID (PID) and that the IDE and the executable 
would always have different PIDs, I cannot fathom how the two could "talk". Nor 
do I, at this point, have any clue whatsoever 
how the gb.debug component is intended to be used.

I was hoping it might give me access to the running properties of the 
HttpClient object. But, I am not going to spend any more 
time on this groping in the dark. I'll just have to look in a different 
direction, or wait until the issue somehow magically 
fixes itself.

Hi Hans,

The commonly used term, "web service", can be a bit misleading since not all 
services accessible over the web (internet) are 
necessarily served by a _web_ server.

The gb.xml.rpc component is not designed to run 'through' a web server in the 
same manner that PHP web services do. This means 
that, in this case, the RPC service cannot be called simply by fetching a file. 
The service must _first_ be started on whatever 
machine is acting as the server. Then, a request can be made to the service, 
already listening on a specific port, by making a 
call to it in the form of http://ip_address:port.

(PHP scripts must be executed by a web server which means the server is already 
running.)

If you are wanting to be able to access an actual web service (PHP-style), then 
I believe you are using the wrong component(s). 
In that case, you should probably use gb.web for the server side and 
gb.net.curl's HttpClient for the client side.

Your client/server application does indeed work just fine (even without gb.web 
and gb.net.curl), provided the server is started 
prior to making the call.

[Gambas-user] gb.debug: Unable to open fifo

[T Lee Davidson]

Hello folks,

I am trying to see if gb.debug will help me diagnose why HttpClient does not 
properly expose redirect response codes on my 
system (and reportedly Tobi's system) while it does so correctly on Benoît's 
system.

However, the documentation for gb.debug is so sparse that I am having to 
experiment and, of course, having a problem.

With the following command-line application code (using the gb.debug component):
' Gambas module file

Public Sub Main()

   Dim sName As String

   sName = Debug.Begin()
   Print sName
   Debug.Start ' Unable to open fifo
   Debug.Write("Hello world")
   Debug.Stop
   Debug.End

End

Public Sub Debug_Read(Data As String)

   Print Data

End
' End Gambas module file

Debug.Start causes an exception: "Unable to open fifo". By looking in 
/tmp/gambas.1000/, I can see that the process id input and 
output pipes are successfully created with the correct file mode permissions 
(600) for my user as owner. But, the Start 
procedure apparently cannot open the output fifo (ref. 
https://sourceforge.net/p/gambas/code/HEAD/tree/gambas/trunk/main/lib/debug/CDebug.c).

Am I attempting to use this component incorrectly?

Re: [Gambas-user] Best way to upgrade Gambas

[T Lee Davidson]

OpenSuse is not much different from any other RPM-based distribution.

On OpenSuse Leap 42, I rely on the Packman repo to keep my Gambas package up to 
date. I do not compile from source.

Uninstalling the packaged version should not remove the necessary libraries 
unless you specifically instruct Yast or Zypper to 
do so. You will, of course, need to have installed the development (-devel) 
versions of certain libraries in order to compile 
your own local version.

If you are attempting to read the data _into_ RxBuffer, it appears your syntax 
is incorrect.

According to http://gambaswiki.org/wiki/lang/read , the syntax for the READ 
statement is:
Variable = READ [ # Stream , ] Length

Perhaps try:
Try RxBuffer = Read #SerialPort1, Lof(SerialPort1)

Actually, I don't think it is a libcurl issue since the first response header 
does contain the appropriate text and code.

If I run the example project with slightly different output:

   rMatch = New RegExp(hClient.Headers[0], ".*? (\\d+) (.*)")
   TextArea1.Text = hClient.Headers[0] & "\n"
   TextArea1.Text &= "Parsed header code: " & IIf(rMatch[1], rMatch[1].Text, 
"No code found.") & "\n"
   TextArea1.Text &= "Parsed header reason: " & IIf(rMatch[2], rMatch[2].Text, 
"No reason found.") & "\n"
   TextArea1.Text &= "HttpClient.Code: " & hClient.Code & "\n"
   TextArea1.Text &= "HttpClient.Reason: " & hClient.Reason & "\n\n"

For the two problem sites, I get:

HTTP/1.1 301 Moved Permanently
Parsed header code: 301
Parsed header reason: Moved Permanently
HttpClient.Code: 0
HttpClient.Reason:

and

HTTP/1.1 302 Moved Temporarily
Parsed header code: 302
Parsed header reason: Moved Temporarily
HttpClient.Code: 0
HttpClient.Reason:


For the 200 & 404 codes, it works as expected.

Thinking it may be a Charset issue, I made sure to send a "Accept-Charset: 
utf-8" header - no difference.

I've taken a quick look at CHttpClient.c and found http_parse_header, but I 
don't understand what "ret = (ret * 10) + (*p - 
'0')", among others(!), does.

I thought so. But, I looked and looked and did not find any way to access that 
flag either in HttpClient or in Curl (gb.net.curl).

The version of libcurl on my system is libcurl4, Version 7.37.0-16.3.1 
(libcurl.so.4.3.0).

BTW, I just tried again to see if it was just a transient issue, but, no, I 
still get neither 301 nor 302.

Thank you for taking the time to check into that, Benoît.

In the meantime, for anyone else needing to loop through redirects (currently 
scanning for a "Location" header), here's a short 
example subroutine:

Private Sub TestPage(sUrl As String)

   Dim hClient As New HttpClient
   Dim iMaxRedirects As Integer = 5 'Prevent infinite loop bot trap
   Dim iCurrentRedirects As Integer = 0
   Dim bFound As Boolean

   hClient.UserAgent = "AppleWebKit"
   hClient.Async = False
   hClient.URL = sUrl
   hClient.Timeout = 15
   Inc Application.Busy
   Do
 bFound = True 'Reset redirect flag
 hClient.Get
 If hClient.Headers.Find("Location:*", gb.Like) > -1 Then
   bFound = False 'Redirection
   If iCurrentRedirects = iMaxRedirects Then Break
   Inc iCurrentRedirects
   hClient.URL = Replace(hClient.Headers[hClient.Headers.Find("Location:*", 
gb.Like)], "Location: ", "")
   Print hClient.URL
   hClient.Headers.Clear 'Must manually clear headers array or "Location" 
header will persist causing redundant looping
 Endif
   Loop Until bFound = True
   Dec Application.Busy

   If hClient.Status < 0 Then
 Print "ERROR"
   End If

   Print "Success? -> " & hClient.Code

End

[Gambas-user] HttpClient not exposing redirect response codes

[T Lee Davidson]

I have run into a couple of sites that are responding with 301 (Moved Permanently) and 302 (Moved Temporarily) codes. However, 
HttpClient.Code yields "0" for both of those sites/codes (and HttpClient.Reason is empty). 200 & 404 codes are reported 
successfully.


Have I missed something in the properties that is preventing proper disclosure 
of redirect response codes?

Or is this a bug?

LOL. To get ungreedy behavior, use greedy quantifiers. That's logical.


Thank you very much, Tobi, for digging that up and updating the documentation.

Perhaps, though, more intuitive behavior would be achieved if the 
RegExp.Ungreedy flag was not set by default. Just a thought.

Thanks again.

[Gambas-user] Problem with lazy regexp

[T Lee Davidson]

According to http://gambaswiki.org/wiki/doc/pcre , using "*?" in a regular expression should lazily match 0 or more characters. 
However, it appears to act greedily.


I am trying to do some very simple HTML tag stripping with 'Regex.Replace(sText, "<.*?>", "")', and it takes out way more than 
just the tags.


Have I misunderstood the documentation?

Re: [Gambas-user] How to dynamically add & populate variable number of tabs at runtime?

[T Lee Davidson]

Thank you, Matti. That got me started.

I now have a working test model that will create a variable (unknown at 
design-time) number of tabs and populate each of them 
with a _visible_ GridView. It works great.

The form now has a ValueBox to input the number of tabs to create, an AddTabs 
button, a PopulateGrids button, and of course a 
TabStrip. Here's the code for anyone else looking for a basic demo. (Note the 
use of the Object.Add method.)


[code]
' Gambas class file

Private aGridViews As New Object[]

Public Sub Form_Open()

   Dim hGridView As GridView

   ValueBox1.Value = 3 'convenience

   TabStrip1[0].Text = "Tab 0"
   TabStrip1.Index = 0

   hGridView = New GridView(TabStrip1) As "GridViews"
   aGridViews.Add(hGridView, 0)
   With aGridViews[0]
 .X = 0
 .Y = 0
 .Width = .Parent.Width
 .Height = .Parent.Height
 .Columns.Count = 2
 .Rows.Count = 2
 .Columns.Width = .Width / 2
   End With

End

Public Sub TabStrip1_Close(Index As Integer)

   TabStrip1.Index = Index
   TabStrip1.Current.Children[0].Delete() 'Comment out to test if tab is empty
   TabStrip1.Current.Delete()

End

Public Sub btnAddTabs_Click()
   Dim i As Integer
   Dim hGridView As GridView

   If ValueBox1.Value = 0 Then Return

   TabStrip1.Count += ValueBox1.Value
   For i = 1 To ValueBox1.Value
 TabStrip1[i].Text = "Tab " & i
 TabStrip1.Index = i

 hGridView = New GridView(TabStrip1) As "GridViews"
 aGridViews.Add(hGridView, i)
 With aGridViews[i]
   .X = 0
   .Y = 0
   .Width = .Parent.Width
   .Height = .Parent.Height
   .Columns.Count = 2
   .Rows.Count = 2
   .Columns.Width = .Width / 2
 End With
   Next

End

Public Sub btnPopulateGrids_Click()
   Dim i As Integer

   For i = 0 To aGridViews.Max
 aGridViews[i][0, 0].Text = "Tab " & i & ": [0,0]"
 aGridViews[i][0, 1].Text = "[0,1]"
 aGridViews[i][1, 0].Text = "Tab " & i & ": [1,0]"
 aGridViews[i][1, 1].Text = "[1,1]"
   Next

End
[/code]

[Gambas-user] How to dynamically add & populate variable number of tabs at runtime?

[T Lee Davidson]

Hello Folks,

I have been trying to figure out how to, at runtime, create a variable number 
of new tabs in a TabStrip, populate those tabs 
with Controls, and then be able to reference those controls, all dynamically.

There seems to be little information available as to how to 1) dynamically 
create controls, and 2) reference dynamically named 
controls after creation.

Even with just a simple experiment, I cannot get a GridView to display in a new 
tab. The Form has been given, at design-time, a 
TabStrip and two buttons. The tabs are 'closable'. One button, 'btnAddTab', 
creates a new tab and a GridView with the new, 
current tab as parent. (At least that's what I think it is doing.) The other 
button, 'btnTabInfo', displays info about the 
currently selected tab.

And, I am assuming the GridViews need to have unique names.

[code]
' Gambas class file


Public Sub btnAddTab_Click()
   Dim hGridView As GridView

   TabStrip1.Count += 1
   TabStrip1.Text = "Tab " & TabStrip1.Index
   hGridView = New GridView(TabStrip1) As "GridView" & TabStrip1.Index
   hGridView.Show
   TabStrip1.Refresh

End

Public Sub btnTabInfo_Click()

   Print TabStrip1.Children[0].Name
   Print TabStrip1.Children[0].Enabled
   Print TabStrip1.Children[0].Visible

End

Public Sub TabStrip1_Close(Index As Integer)

   TabStrip1.Index = Index
'   TabStrip1.Current.Children[0].Delete() 'Comment out to test if tab is empty
   TabStrip1.Current.Delete()

End
[/code]


Tab creation works, but the GridView control does not display. Any attempt to 
close a tab without first deleting its children 
causes an exception, showing that the tab is indeed being populated with a 
child control. Clicking on btnTabInfo for "Tab 1" gives:
GridView1
True
True

So, the program is doing at least some of what I've told it to. I'm obviously 
not telling it the right thing.

How does one:
1. Create new controls and make them visible?
2. Reference new controls after creation [ie. (de-)reference a string as a the 
name of a control]?

I'm not certain it is an error in _your_ source code.

Whatever distribution you are using may likely did not automatically install 
ALL of the Gambas components. For this particular 
project, you will probably need to also install the gambas3-gb-desktop and 
gambas3-gb-media (however they are named in your 
distro) components.

I am really confused as to what you are attempting. You say the Main form has 
no code, but then you show code for a private 
subroutine named "$load" which, as far as I know, does not exist in Gambas.

And, if you are creating a graphical application with the IDE, there should be 
no need to include the "Inherits Form" statement. 
It appears as though you may be trying to create a (graphical) form from a 
non-graphical command line application. But, that is 
difficult to determine without seeing your code.

If you could attach a small project file so we can better see what you are 
trying to do, it might help.

In the meantime, perhaps what you need is the Form_Open event handler:

Public Sub Form_Open()

   With Me
 .MoveScaled(0,0,64,64)
   End With

End

If applicable, see the examples at: http://gambaswiki.org/wiki/comp/gb.qt4/form

Wait, duh. I forgot you don't actually need code when using the DataBrowser.

I got it to run. It works as expected here.

I don't know what happened with the archive, but after extraction there is no 
code in the FMain.class file. Just the default 
comment, "' Gambas class file", and nothing else.

FMain.form is there, though, with a DataSource containing a DataBrowser.

[Gambas-user] Set timeout for Webview?

[T Lee Davidson]

I am trying to fetch a web page through a private SOCKS5 proxy using Basic 
Authentication with:
   Try hWebView.Url = sUrl
   If Error Then Message.Error("Error retrieving page", "OK")

If the proxy is nonresponsive, the application just hangs, apparently doing 
nothing. Sometimes it will timeout after 120-some 
seconds. But I get no error message, just an empty response. (HttpClient has a 
Timeout, but I cannot use that for this application.)

I see no timeout property for either WebView or WebSettings. Is it possible to 
set a timeout for WebView?

[code]
' Gambas class file

Public sOutput As String

Public Sub Form_Open()
   TextArea1.Insert("#>")
End

Public Sub TextArea1_KeyPress()
   If Key.Code <> Key.Enter And Key.Code <> Key.Return Then Return
   Stop Event
   Shell Right(Split(TextArea1.Text, "\n").Pop(), -2) To sOutput
   TextArea1.Insert("\n" & sOutput & "#>")
   TextArea1.EnsureVisible   ' (That's nice, Benoît.)
End
[/code]


You can of course change the default colors of the TextArea to a light on dark 
to simulate a terminal. But, the cursor will 
likely become invisible and is not easily changed.

I have to assume that "fntexc" is a 'global' since it is not declared in the 
Sub.

This code...

' Gambas module file

Public fntexc As String[]

Public Sub Main()

   Dim sFont As String

   fntexc = []
   setFontNameList(["courier", "helvetica", "arial"])
   For Each sFont In fntexc
 Print sFont
   Next
End

Public Sub setFontNameList(fontliste As String[])
   Dim i As Integer

   Debug fontliste.Count

   fntexc.Clear

   For i = 0 To fontliste.count - 1
 fntexc.Add(fontliste[i])
   Next

End

...works, and outputs:
MMain.setFontNameList.19: 3
courier
helvetica
arial


Hope that helps,

[Gambas-user] How to set HttpClient Accept headers?

[T Lee Davidson]

I know that the ACCEPT_ENCODING client header can be set using 
HttpClient.Encoding per the wiki. And, I believe 
HttpClient.Headers are only the server response headers.

Is it possible to also set the ACCEPT and ACCEPT_LANGUAGE client headers for 
HttpClient?

Re: [Gambas-user] Create a Form like Panel on Desktop

[T Lee Davidson]

You shouldn't need to do anything special in Gambas to accomplish that. Your 
window manager should be able to do that.

For example, in KDE, you would click the application icon at the very top-left 
in the title bar, choose "More Actions" and then 
"Keep Above Others". I don't know about other window managers.

Or, is that not what you meant?

I don't know if it's related, but I noticed that Gambas does not seem to

I cannot help you understand it, GianLuigi, because I don't understand it either. But, I can say that it didn't play nice with 
my KDE Plasma v5.5.5 on Qt v5.5.1. It kept repeatedly crashing Plasma in a loop until I killed it.

Re: [Gambas-user] Repository of GAMBAS programs

Yes: http://gambaswiki.org/wiki/app

But, some of the apps are a bit outdated.

The new repository is the Gambas Farm which is accessible from within the 
Gambas IDE in versions, I think, greater than 3.8.X. 
(Someone please correct or confirm the version number.)

Re: [Gambas-user] Gambas mime type

[T Lee Davidson]

Matti,

I was wrong about the pattern in 
"/usr/share/mimelnk/application/x-gambas3.desktop". That mimetype file is for 
Gambas scripts, 
not Gambas executables.

And, I recommend ignoring my instruction to create 
"~/.local/share/applications/gbr3.desktop". It might be much better to just 
create the association in System Settings.

Once there, go to Applications -> File Associations and search on "gambas". 
There should be two there already which you can use 
as examples to create a "x-gambas" type. You can switch back an forth between 
the types as you create the new one.

I chose the "application-x-gambas" icon from System icons, added "*.gambas" as 
a filename pattern, described it as "Gambas 
executable", and added "/usr/bin/gbr3" in Application Preference Order.

Once I clicked Apply, the file, "~/.local/share/applications/gbr3.desktop", was 
created and the mimetype database updated 
automatically.

Matti,

I think the mistake in "/usr/share/mimelnk/application/x-gambas3.desktop" is 
the Patterns being set to "*.g;*.G". I tried 
correcting that to "*.gambas;*.Gambas" on my system. But, I got impatient and 
didn't want bother seeing if a reboot would cause 
the new pattern to be picked up.

Here's a quick fix.

Ensure that you have a file "~/.local/share/applications/gbr3.desktop" with the 
content:
[Desktop Entry]
Exec=/usr/bin/gbr3
MimeType=application/gambas;
Name=gbr3
NoDisplay=true
Type=Application

(It can sometimes take a minute or so for the system to recognize changes in 
"~/.local/share/applications".)

Then go to System Settings -> Applications -> File Associations. Search for 
"gambas". It should be:
Filename patterns: *.gambas
Description: application/gambas
Application Preference Order: gbr3

If it's not there, add it.

Yes, I agree since the Mode for String[].Sort is integer and 
GridView.Columns.Ascending is boolean.

But, how about this?
ValueSorted.Sort(IIf(TableView1.Columns.Ascending, gb.Ascent, gb.Descent))

That's exactly what I needed, Gianluigi. Thank you.

It works well even preserving distinct rows with duplicate key values.

I added a few comments to your code and added it as an example to 
http://gambaswiki.org/wiki/comp/gb.qt4/gridview/sorted. (I 
hope that's okay with you. If not, please let me know and I'll modify or remove 
it.)

Re: [Gambas-user] How to sort a TableView?

[T Lee Davidson]

Thank you, Frank.

That is an interesting example. It uses an array of variant arrays as the 
underlying data-store similar to what I had done in 
the past with objects. And, they extend Object[] with a custom sort routine. 
Neat.

Re: [Gambas-user] How to sort a TableView?

[T Lee Davidson]

Thank you for your effort, Gianluigi. But, I am not using a database; just a 
TableView of data.

When a TableView's Sorted property is set to True, clicking on a column header 
toggles the sort indicator and raises the 
TableView's Sort event.

I need to sort the TableView rows based on the values in whichever column the 
header was clicked.

[Gambas-user] How to sort a TableView?

[T Lee Davidson]

The documentation for TableView shows a Sorted property which says, "Sorting 
the data is not done automatically. It must be done 
by user code." But, the page does not give any clues regarding how to 
accomplish that. Though, obviously, sorting should be done 
in the Sort event handler.

In the past, I have used an array of objects to store the data represented in 
the TableView. This provided use of Object[].Sort 
with the _compare function.

This time around, I am attempting to eliminate the redundancy of duplicate data 
containers (store and view) and the cumbersome 
syncing of the data and the view. (Perhaps I should just simply use a SQLite DB 
and a DataView?)

There appears to be no TableView/GridView or GridView.Columns Sort method.

Does anyone have any hints as to how to sort a TableView?

So, does anyone know how I might be able to log in to the Wiki? Either by 
retrieving or resetting my password? Or, by 
re-registering?

In other words:

If it exists, where is the Reset Password link?
Or, where is the Register link?

Thanks Tobi. And, yes, I did not think there should be any documentation 
necessary for logging in.

But as I said, I cannot log in. After submitting the login form, the "Login" 
button remains; no "Logout" button. I get no error 
message, nor any link to retrieve password, nor any link to register. I just 
figured there _must_ be something I am missing that 
is perhaps documented somewhere that I cannot find.

[Gambas-user] How to register and login to the Wiki?

[T Lee Davidson]

I used to be able to login to the Wiki (http://gambaswiki.org/). This was prior 
to it receiving its new face.

Now, I cannot login apparently. When I enter my login credentials, I see no 
evidence of being logged in and still see the 
"Login" button. There is also no recover password, nor register, link.

Has the procedure for registering/logging in changed, and I simply cannot find 
the documentation explaining it?

I am also interested in this issue since I think it may be related to why I am 
unable to install the IDE on OpenSUSE Leap 42.1.

Just for informational purposes since I do not wish to highjack this thread, 
the SPEC file from the OpenSUSE Build Service 
defines a "gb-qt5-ext" component as required for the IDE when not "with qt4". 
But, as far as I can tell, this component is not 
provided by the sources.

Hopefully a resolution to this issue on Debian will also provide a path to 
resolve the issue on OpenSUSE.

I thought indeed this was my solution, Fabien. But alas, it does not work for 
me on Qt.

I don't have 'xdotools', Charlie, so I didn't give your interesting solution a 
try. But, it did give me an idea. And the 
solution is so simple.

This works for me on Qt:

Public Sub TableView1_Activate()

   TableView1.Edit()
   Desktop.SendKeys("{[Control_R]a}")

   Return

End


Thank you all for your responses.

[Gambas-user] How to automatically select all text when first entering editable TableView cell?

[T Lee Davidson]

I have a project with a TableView that has the cells of certain columns defined 
as editable since the content can change.

The problem is when the user is editing a row and uses either ENTER or an arrow 
key to move to the next editable cell, any 
existing text in the cell gets in the way and needs to be manually deleted. 
It's a little annoying to have to continually use 
the delete key, or double-click to select all the text.

I'd like all the text to be selected when the cell is first entered via the 
keyboard, but I cannot figure out how to do that.

The TableView.Activate event is raised when a cell is entered, and so I have 
tried the following:

[code]
Public Sub TableView1_Activate()

   Dim hTextBox As TextBox

   TableView1.Edit()
   hTextBox = TableView1.Editor
   hTextBox.Select()

End
[/code]

(Note: TableView.Editor is a Control and hence does not have a Select method. 
But TableView.Edit uses a TextBox control by 
default to edit the cell.)

But, it doesn't work. No error is raised, but the text is not selected.

Any ideas?

So here I thought I was helping others who may have been in the same situation. 
As it turns out, I've just caused alot of noise 
because the issue was not related to the DBus Name at all. Unfortunately, I 
haven't the slightest clue how I didn't get an error 
with the fix I presented.

The original DBus object class file I was using:
--
' DBusInterface class file

Inherits DBusObject
Create Static

Public Sub Receiver(myString As String)
   Print "Received: " & myString
End
--

And, I said the fix was to do some name swapping before sending the data:

 ' ' Send command line args to existing instance
 ReceiverDbusName = DBus.Name 'Preserve receiver name
 DBus.Name = "org.gambas.Transient" & Application.Name  ' Set different 
name for transient relay of args.
 DBus[ReceiverDbusName]["/DBusInterface"].Receiver("command line arguments")


WRONG!!

Don't bother with name swapping. It isn't necessary. When Gambas makes a call 
of the format 
"DBus[Application][ObjectPath].Method(Arguments)", it does not create a 
connection on the bus with the name of DBus.Name. It 
allows the DBus daemon to create a generic, number-formatted-name connection.

The real problem, I've discovered, was in the DBusInterface class code.

According to 
https://dbus.freedesktop.org/doc/dbus-specification.html#message-protocol-types 
:
"When an application handles a method call message, it is required to return a 
reply."

And, as you can see, the created DBusInterface object would do no such thing. 
The example class code should be:
--
' DBusInterface class file

Inherits DBusObject
Create Static

Public Sub Receiver(myString As String) As Boolean '** Return type
Print "Received: " & myString
Return True '** Return a reply
End
--

[Gambas-user] 'Single instance' app cannot reuse DBus.Name

[T Lee Davidson]

A single instance application is one in which only one instance is allowed to 
be running at the same time. Checking for an 
existing instance is quite regularly done simply with some sort of lock file or 
socket. If a lock is found, then just quit the 
app. But suppose you want to pass the current command line arguments along to 
the existing instance.

DBus is handy for that. We can check to see if our DBus.Name, 
"org.gambas.[Application.Name]" by default, is already registered 
on the bus and behave accordingly. The pseudo-logic is:

If DBusName.IsRegistered.With.DbusSessionDaemon  ' There is already an instance 
running
   Send the command line args, via message, to the existing (primary) instance 
and quit out of the transient instance
Else
   Go ahead and start a 'primary' instance and register our DBus.Name on the bus
End


In Gambas, we would send the message to the existing instance using the general 
format 
"DBus[DBus.Name][/Path/To/MyDBusObject].inMethod()".  But, apparently, this 
particular format invisibly tries to register a 
connection on the bus using DBus.Name. This causes a problem, because you 
cannot register the same name on the bus more than once.

In other words, even if you don't explicitly connect and register a name on the 
bus, simply trying to send a message on the bus 
causes an intrinsic registration; and, an exception.  And you cannot use a 
random, guaranteed-unique name for DBus.Name or else 
you wouldn't know what it is and would have no way of knowing 'who' to send the 
message to.

The solution is to change Dbus.Name in the transient instance just prior to 
passing along the command line data. Here is my 
original, error-producing code:

--
' DBusInterface class file

Inherits DBusObject
Create Static

Public Sub Receiver(myString As String)
   Print "Received: " & myString
End

---

' Gambas module file

Public Sub Main()
   If DBus["org.freedesktop.DBus"]["/"].NameHasOwner(DBus.Name)
 Print DBus.Name & " already has an owner."  ' Only one instance allowed
 ' ' Send command line args to existing instance
 DBus[DBus.Name]["/DBusInterface"].Receiver("command line arguments")  ' 
*[1] *[2]
 Quit
   Else
 DBus.Session.Register(DBusInterface, "/DBusInterface")
 Print "Press Ctrl+C to quit."
 While True
   Wait 0.1
 Wend
 DBus.Session.Unregister(DBusInterface)
   Endif
End
--

*[1]:   That line caused "org.freedesktop.DBus.Error.Failed: No return value",
and a Segmentation Fault; even though no return value should have been 
expected.


The fix was to do some name swapping:

 ' ' Send command line args to existing instance
 ReceiverDbusName = DBus.Name 'Preserve receiver name
 DBus.Name = "org.gambas.Transient" & Application.Name  ' Set different 
name for transient relay of args.
 DBus[ReceiverDbusName]["/DBusInterface"].Receiver("command line arguments")


Problem solved! :-)

[Gambas-user] DBus.IsRegistered --> Unknown symbol

[T Lee Davidson]

I am developing an application that conditionally registers an object on the 
DBus session bus. I have to use the Form_Close 
event to, if it was registered, unregister the object or the form will close 
but the application will not stop.

Based on http://gambaswiki.org/wiki/comp/gb.dbus/dbus/isregistered :
[quote]
DBus.IsRegistered (gb.dbus)

Static Function IsRegistered ( Object As DBusObject ) As Boolean

Return if the specified object is registered on a DBus bus.
[/quote]

my code is:
[code]
Public Sub Form_Close()

   If DBus.IsRegistered(MyDBusObject) Then
 DBus.Session.Unregister(MyDBusObject)
   Endif

End
[/code]

When the form is closed, I get, "Unknown symbol 'IsRegistered' in class 'Dbus'".

Did I miss something in the documented syntax?


As a temporary workaround, I can use:
[code]
   If DBus["org.freedesktop.DBus"]["/"].NameHasOwner(DBus.Name) Then
 DBus.Session.Unregister(MyDBusObject)
   Endif
[/code]

But that is not very granular.

To be in compliance with the Linux Filesystem Hierarchy Standard, shouldn't the 
use of '/usr/local' be considered?

http://refspecs.linuxfoundation.org/FHS_3.0/fhs/ch04s09.html:
"4.9.1. Purpose

The /usr/local hierarchy is for use by the system administrator when installing

I think that means different *formats* of the same data. For example, mail 
generally can be sent in text only, in HTML, or in 
both text and HTML. Those are just different formats of the same email message 
(data).

Sending the message formatted as both text and HTML allows the mail client to 
choose which format it prefers. Apparently, though 
I cannot say with certainty, attachments can be handled similarly.

There are a couple of reasons why the code doesn't work as I think you are 
expecting.

1. Because the syntax, dbclick = +1, assigns positive 1 to dbclick each time 
it is executed. The syntax should be dbclick += 
1, or Inc dbclick.

2. You have declared dbclick within the function and it therefore gets, 
essentially, reset to 0 on each call of the function.

I think it may actually be working. You just cannot see that it is, because the 
code after the just_keep_moveing label is 
resetting the value of TextBox1.text.

After performing the If $dbclick = 8 test the program drops through and 
executes the just_keep_moveing code no matter what 
the value of dbclick is. Depending on what the just_keep_moveing code is 
supposed to do, you may need to move it to *inside* 
the Else block.

You could either set a breakpoint at or just before the Else and examine the 
value of TextBox1.text, or place a 'Print hello' 
statement just after If $dbclick = 8 then to see if hello is printed to the 
IDE console. If it is, then the If $dbclick = 
8 test *is* working and you need to rethink the program's logic.

Re: [Gambas-user] Question on preserving Windows EOL

[T Lee Davidson]

On 05/17/2015 10:18 AM, Willy@develop wrote:
 Hi All,

 I've been struggling with something I would like to implement.

 A user asked me if it would be possible to preserve Windows EOL (CRLF)
 for files originating from Windows, but opened and modified in gbEdit
 (Gambas written texteditor).

 What happens now is that, if I add a few new lines to a windows
 originated text file, the new lines will be saved with a linux EOL (LF).
 The lines already having the Windows EOL (CRLF) are preserved.

 gbEdit makes use of a Editor control. Saving the contents is now done
 with a simple:

 File.Save($sPathFileLoaded, editMain.Text)

 Where $sPathFileLoaded is the full path and name of the file
 AND
 editMain.Text is the name of the Editor control holding the content.

 Upon opening a file gbEdit determines the EOL and returns either:
 CRLF for Windows EOL
 LF for Unix EOL
 CR for Classic Apple Mac EOL

 So I have all in place to determine when Windows EOL needs to be used
 upon saving.

 What I need is that new lines added, to a file already using Windows
 EOL, have to be saved with Windows EOL as well.

 I imagine I could save the file as a stream, making sure the proper EOL
 is added, but was wondering if there might be any easier way in Gambas
 that can do the job (as somehow that often turns out to be the case).

 Any suggestions?



Effect the necessary EOL-type upon data entry by either:

#1) A new property for the Editor control that is set to the EOL-type of the 
text and ensures that RETURN and ENTER effect the appropriate characters, or

#2) Trapping the RETURN and ENTER key events to effect the appropriate 
characters.

I haven't looked further into either idea. They are just off the top of my head.

The environment variable for the user's home folder is not $home, but 
$HOME. 
Maybe also try ~/.myprogram.

Re: [Gambas-user] Embed a specific SQLite version

[T Lee Davidson]

Hi Christian,

To use SQLite  3.8.3, you'll probably just need to install it on your system; 
either by compiling and installing, or by building a .deb package to install. I 
don't use any flavor of Ubuntu, so I can't help with that.

Nor can I help with your deployment question.

 Hi Folks,
 Is it possible to make Gambas access a specific version of SQLIte?

 I mean, I'm using a Linux Mint 17.1 (based on Ubuntu 14.04 packages).
 In this way, the system installs the SQLIte version 3.8.2 (that's the
 only that is available at the repositories 14.04). But I need to use
 SQLIte version 3.8.8 (at least 3.8.3 ahead...). Is it possible to
 embed a specific SQLite driver in my Gambas application so it can
 access the database independent of the SQLite driver of the Linux
 System.

 Is it possible to deploy my application with this specific SQLite driver?

 It's so important because I need to use Common Table Expressions
 (CTE), that's available only in SQLIte 3.8.3 ahead.

I haven't actually done this, so I hope someone will correct me if I am wrong. 
But, I believe you would list your .so file in the Extra Files (step #8)

This may be over-simplified, but couldn't you define a DateRange structure? Or

 I could ignore the array length and just use DateRange[0] and DateRange[1] as 
 the limits but that may produce confusing outcomes, or an error if DateRange 
 contains only one element.

 I would like to define the function as GetCurrent(DateRange as Date[2]) but 
 this is apparently a syntax error.

 Obviously, in this trivialised example, I could check the bounds of the 
 passed array in the function body, I just expected that the runtime would  
 check an explicitly sized array parameter. The real function is (of course) 
 much more complex. The function requires an array of Dates[3][2] and another 
 5 parameters, some of which are optional.

 Any thoughts?

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

[T Lee Davidson]

Could be a problem with the keyring on your desktop. On KDE, the default 
keyring 
is 'kwallet'. Not sure what it would be on Linux Mint 17 with Mate. Perhaps 
'mate-keyring', or, more likely, 'gnome-keyring'.

If you have it disabled or it is having issues, Gambas would/could have 
difficulty connecting with it.

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

[T Lee Davidson]

Martin,

I must apologize for slightly misleading you.
The .Update method is the more appropriate one to use to reload the data in the 
event of a canceled edit.
The .Update method can be applied to the DataSource and it will update all 
bound children.

And, yes, logically, if you create a record and then do not populate it with 
data, you would have added a blank record to the DB.
But it really depends on how you create the record to begin with.

For example, the clicking the New button in the Databrowser does not create a 
new record in the database until the data is Saved.

[T Lee Davidson]

Well, looks like I was wrong again.

Despite the documentation for DataSource.Update saying,
Reload the DataSource data and update all bound child controls accordingly,
it apparently tries to write to the database.

The .Cancel method is the one to use to, uh, cancel any current modifications.
DataSource.Cancel: Cancel any current edition of child controls.


Simple sample attached.

 Mr. Speaker,

 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  :-\

 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.
