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:

  1. a simplified and extensible API for forms, dialogs and controls manipulations similar with the Microsoft Access object model,

  2. an API for database access with the table, query, recordset and field objects,

  3. a number of actions with a syntax identical to their corresponding Microsoft Access macros/actions,

  4. the DLookup, DSum, ... database functions,

  5. el suport de la notació curta com Forms!myForm!myControl

in addition

  1. a consistent errors and exceptions handler,

  2. facilities for programming form, dialog and control events and

  3. the support of both embedded forms and standalone (Writer) forms.

   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
