SFDocuments.Base service

The Base service provides a number of methods and properties to facilitate the management and handling of LibreOffice Base documents.

This service is closely related to the Document service, which provides generic methods for handling LibreOffice documents, including Base documents. Hence, the Base service extends the Document service and provides additional methods that are specific for Base documents, enabling users to:

• Get access to the database contained in a Base document.

• Open form documents stored in a Base document.

• Check if a form document from a Base document is currently loaded.

This service is available from LibreOffice 7.2 onwards.

Refer to the Document service to learn more about methods and properties that can be used to manage LibreOffice documents.

Service invocation

The Base service can be invoked in a variety of ways. The code snippet below uses the method CreateBaseDocument from the UI service to create a new Base file.

Note that in all examples the object oDoc is an instance of the Base service.

    Dim ui As Object, oDoc As Object
    Set ui = CreateScriptService("UI")
    Set oDoc = ui.CreateBaseDocument("C:\Documents\MyFile.odb")
  

The Base service can also be instantiated while opening an existing Base file, as shown below:

    Set oDoc = ui.OpenBaseDocument("C:\Documents\MyFile.odb")
  

If a Base document is already open, it is possible to instantiate the Base service directly:

    Dim oDoc As Object
    Set oDoc = CreateScriptService("SFDocuments.Document", "MyFile.odb")
  

The examples above can be translated to Python as follows:

    from scriptforge import CreateScriptService
    ui = CreateScriptService("UI")
    doc = ui.CreateBaseDocument(r"C:\Documents\MyFile.odb")
  

    doc = ui.OpenBaseDocument(r"C:\Documents\MyFile.odb")
  

    doc = CreateScriptService("SFDocuments.Document", "MyFile.odb")
  

The use of the "SFDocuments." substring in the previous example is optional.

FormDocuments

Returns an array with the full names (path/name) of all form documents in the Base document as an zero-based Array of strings.

svc.FormDocuments(): str[0..*]

The code snippet below prints the names of all form documents in the current Base document.

    Dim oDoc as Object, myForms as Object, formName as String
    Set oDoc = CreateScriptService("Document", ThisDataBaseDocument)
    Set myForms = oDoc.FormDocuments()
    For Each formName In myForms
        MsgBox formName
    Next formName
  

    bas = CreateScriptService("Basic")
    doc = CreateScriptService("Document", bas.ThisDataBaseDocument)
    myForms = oDoc.FormDocuments()
    for formName in myForms:
        bas.MsgBox(formName)
  

To learn more about form documents, refer to the Form service help page.

Forms

Depending on the parameters provided this method will return:

• A zero-based Array with the names of all the forms contained in a form document (if the Form argument is absent)

• A SFDocuments.Form object representing the form specified in the Form argument.

svc.Forms(formdocument: str): str[0..*]

svc.Forms(formdocument: str, form: str = ''): svc

svc.Forms(formdocument: str, form: int): svc

formdocument: The name of a valid form document as a case-sensitive string.

form: The name or index number of the form stored in the form document. If this argument is absent, the method will return a list with the names of all forms available in the form document.

Although it is possible to use index numbers to refer to forms, this is only recommended when there is just one form in the form document. If there are two or more forms, it is preferable to use the form name instead.

The first line of the example below returns a list of all forms in the form document "myFormDocument". The second line returns an instance of the Form service representing the form "myForm".

    Dim formsList as Object : formsList = oDoc.Forms("myFormDocument")
    Dim oForm as Object : oForm = oDoc.Forms("myFormDocument", "myForm")
  

    formsList = doc.Forms("myFormDocument")
    form = doc.Forms("myFormDocument", "myForm")
  

GetDatabase

Returns an instance of the Database service that allows the execution of SQL commands on the database defined and/or stored in the current Base document

svc.GetDatabase(user: str = '', password: str = ''): svc

user, password: Optional login parameters as strings. The default value for both parameters is an empty string "".

    Dim myDoc As Object, myDatabase As Object, ui As Object
    Set ui = CreateScriptService("UI")
    Set myDoc = ui.OpenBaseDocument("C:\Documents\myDb.odb")
    ' User and password are supplied below, if needed
    Set myDatabase = myDoc.GetDatabase()
    '   ... Run queries, SQL statements, ...
    myDatabase.CloseDatabase()
    myDoc.CloseDocument()
  

    ui = CreateScriptService("UI")
    myDoc = ui.OpenBaseDocument(r"C:\Documents\myDb.odb")
    myDatabase = myDoc.GetDatabase()
    '   ... Run queries, SQL statements, ...
    myDatabase.CloseDatabase()
    myDoc.CloseDocument()
  

IsLoaded

Returns True if the specified FormDocument is currently open.

svc.IsLoaded(formdocument: str): bool

formdocument: The name of a FormDocument to be checked, as a case-sensitive string.

    If Not oDoc.IsLoaded("myFormDocument") Then
        oDoc.OpenFormDocument("myFormDocument")
    End If
  

    if not doc.IsLoaded("myFormDocument"):
        doc.OpenFormDocument("myFormDocument")
  

OpenFormDocument

Opens the specified FormDocument either in normal or in design mode.

If the form document is already open, it is activated without changing its mode. The method returns True if the form document could be opened.

svc.OpenFormDocument(formdocument: str, designmode: bool = False): bool

formDocument: The name of the FormDocument to be opened, as a case-sensitive string.

designmode: If this argument is True the FormDocument will be opened in design mode.

Most form documents are stored in the root of the Base document and they can be opened simply using their names, as in the example below:

    oDoc.OpenFormDocument("myFormDocument")
  

If form documents are organized in folders, it becomes necessary to include the folder name to specify the form document to be opened, as illustrated in the following example:

    oDoc.OpenFormDocument("myFolder/myFormDocument")
  

    doc.OpenFormDocument("myFormDocument")
  

    doc.OpenFormDocument("myFolder/myFormDocument")
