Access2Base
What is Access2Base?
L'Access2Base és una biblioteca de macros del LibreOffice Basic per a desenvolupadors d'aplicacions (de negocis o personals) i usuaris avançats. És una de les biblioteques emmagatzemades a «Macros i diàlegs del LibreOffice».
The functionalities provided by the implemented macros are all directly inspired by Microsoft Access. The macros are callable mainly from a LibreOffice Base application, but also from any LibreOffice document (Writer, Calc, ...) where access to data stored in a database makes sense.
L'API de l'Access2Base està dissenyada per ser més concisa, intuïtiva i fàcil d'aprendre que l'API estàndard de l'UNO (API = interfície de programació d'aplicacions, per les seues sigles en anglés).
The library is documented online on http://www.access2base.com.
Les macros implementades inclouen:
-
a simplified and extensible API for forms, dialogs and controls manipulations similar with the Microsoft Access object model,
-
an API for database access with the table, query, recordset and field objects,
-
a number of actions with a syntax identical to their corresponding Microsoft Access macros/actions,
-
the DLookup, DSum, ... database functions,
-
el suport de la notació curta com Forms!myForm!myControl
in addition
-
a consistent errors and exceptions handler,
-
facilities for programming form, dialog and control events and
-
the support of both embedded forms and standalone (Writer) forms.
Compare Access2Base with Microsoft Access VBA
REM Open a form ...
OpenForm("myForm")
REM Move a form to new left-top coordinates ...
Dim ofForm As Object ' In VBA => Dim ofForm As Form
Set ofForm = Forms("myForm")
ofForm.Move(100, 200)
REM Get the value of a control ...
Dim ocControl As Object
ocControl = ofForm.Controls("myControl")
MsgBox ocControl.Value
REM Hide a control ...
ocControl.Visible = False
REM ... or alternatively ...
setValue("Forms!myForm!myControl.Visible", False) ' Shortcut notation
' In VBA => Forms!myForm!myControl.Visible = False
