Re: [Gambas-user] collection of collection problem
Hi Lenz,
GambasForge was not an Community project but my own project at first.
That's why it is not conventionnal.
The goal was just to give a place for french people to share gambas
programs and code piece. This was also for me my first try on gambas
cgi.
Why hidding urls ? well in fact it's not really hidding it's making it
more human readable. In fact in a rewritted url you have all the
needed stuff to generate the true url.
http://gambasforge.org?section=forge&action=code&id=2
Main Sub Main()
Call the dispacher thatcall the Function CCode.VoirCode
'It's ShowCode for english speakers
Public Sub VoirCode()
Dim tCode As Code
Dim id As Integer
'check the id value integrity
If IsInteger(Request.Get!id) Then id = Request.Get!id
If id < 1 Then Error.Raise("Invalid id.")
'Getting the code datas in a specialzed structure
tCode = MCode.VoirCode(Id)
If Not tCode Then
Main.Erreur("Ce code n'existe pas.")
Main.RedirectPage("forge.html")
Return
Endif
' Get the code commentary if any
tCode.Commentaires = MCode.VoirCommentaires(tCode.Id)
'Drawing the page
' Call the common header
CMain.Top()
'Add some scripts
ThisPage.Scripts.Add("js/forge.js")
ThisPage.StyleSheets.Add("css/code.css")
' Adding the codepage
VCode.VoirCode(tCode, MMain.MembreConnecte())
'add the bottom
CMain.Bottom
'Render the full tree at once
Main.Show
End
All the site is based on a virtual html Dom Tree. That during this
period that i've begin my idea of Html tree. And then Adrien have re
writted all the stuff in C and generated the gb.xml.html component.
The advantage of the tree is I can modify my header or adding some
script from every where. So for example the VoirCode function can
display Messages in the standart header. Then with the time some part
become objects like HtmlRecaptcha there are all stored in FormElements
sub directory.

[Gambas-user] Help with Observer 'Stop Event'
I have an observer on a ValueBox control to prevent it changing to zero and to prevent it becoming larger than the value in a different ValueBox. Public Sub valNumObserver_change() If valNum.value = 0 Then valNum.Value = 1 If valNum.Value > valDen.Value Then Stop Event End With first case, where the zero value is changed to one, works. But the Stop Event doesn't do what I expect (it does nothing actually) in the second line... -- View this message in context: http://gambas.8142.n7.nabble.com/Help-with-Observer-Stop-Event-tp58715.html Sent from the gambas-user mailing list archive at Nabble.com. -- Check out the vibrant tech community on one of the world's most engaging tech sites, Slashdot.org! http://sdm.link/slashdot ___ Gambas-user mailing list Gambas-user@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/gambas-user

But the Stop > Event doesn't do what I expect (it does nothing actually) in the second > line... > The documentation about Stop Event [1] says: This statement must be used in an event handler. It tells the interpreter that the event that called the event handler must be cancelled. This may have mislead you to overestimate what the interpreter does when it encounters a Stop Event. What roughly happens when an object raises an event, by using the Raise keyword, is: (1) all "before" observers receive the event, then (2) the default observer of the object receives the event, and lastly (3) all "after" observers receive the event. For each observer, the corresponding event handler is called and as soon as one of these event handlers use Stop Event, this whole chain is aborted. But that's about all the interpreter can do. It stops propagation of the event to later observers. Imagine that your Observer object is one of potentially many observers waiting in line to be notified of the ValueBox Change event. By using Stop Event you tell the interpreter to skip those observers behind you, which have not seen the event yet. At that point, the program flow gets back to the ValueBox -- but the important fact is, for the component programmer, the one who wrote the ValueBox code, obeying Stop Event is completely voluntary. What he does is out of the interpreter's reach. The programmer can choose to get a notification of whether the event was aborted by getting the return value of the Raise keyword: Dim bCancel As Boolean bCancel = Raise Change This value tells him if someone called Stop Event or not. But he is free to ignore that value, or to react to it however he wants. He may even abort the event whenever you tell him not to. Now look at the source code of ValueBox (comp/src/gb.form/.src/ValueBox.class): --8<---[ $ grep -C 2 "Raise Change" ValueBox.class ] If $hTextBox.Text <> $sLastText Then $sLastText = $hTextBox.Text Raise Change Endif -- Public Sub DateBox_Change() Raise Change End -- Public Sub CurrencyBox_Change() Raise Change End -- Public Sub IpAddressBox_Change() Raise Change End --8< The programmer chose to ignore Stop Event for every instance of raising the Change event [*]. I'm not sure if there is anything you can do about it, apart from dirty hacks or writing your own ValueBox. Maybe you should just try and ask Benoit to add support for Stop Event in the ValueBox. Regards, Tobi [*] This is normal actually. You can grep through the source tree for "= Raise" on the one hand and "^ *Raise" on the other. It gives me a ratio of 28/865, so about 3% of Raise statements even consider the possibility that the user Stop Event's them. This is only counting non-native Gambas events, though.

that's awesome.. the gb.xml module are so usefully for parsing some socket
messages and emulates and webservice.. my only problem its a lack of
authentication and session handler
now that's the reason of the tree parsing mode of the code.. thanks for

Re: [Gambas-user] Time, date & Settings
OK, forgot to update Gambas on my virtual machine... But now there is another problem. I'm in UTC+3, and when I write the time (example 12:00) with CStr(), it will be 15:00 in the settings file. Now if I go to UTC-0, I will get the alarm when my computer clock shows 15:00. I want it always assume local time. Example if I have meeting in UK at 31.3.2017 12:00, I want simply set the alarm for 31.3.2017 12:00, independently of where I'm now. The device I'm using should worry about timezones not me.
