# 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.

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

## Service invocation

Before using the Base service the ScriptForge library needs to be loaded or imported:

• Basic macros require to load ScriptForge library using the following statement:
GlobalScope.BasicLibraries.loadLibrary("ScriptForge")
• Python scripts require an import from scriptforge module:
from scriptforge import CreateScriptService

##### In Basic

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")

##### In Python

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.

List of Methods in the Base Service
CloseFormDocument FormDocuments Forms | GetDatabase IsLoaded OpenFormDocument | PrintOut SetPrinter

## CloseFormDocument

Closes the given form document. Returns True if closure is successful.

### தொடரமைப்பு:

svc.CloseFormDocument(formdocument: str): bool

### அளவுருக்கள்:

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

### எடுத்துக்காட்டு:

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

##### In Basic

        oDoc.CloseFormDocument("Folder1/myFormDocument")

##### In Python

        doc.CloseFormDocument('Folder1/myFormDocument')

## FormDocuments

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

### தொடரமைப்பு:

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

### எடுத்துக்காட்டு:

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

##### In Basic

        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

##### In Python

        bas = CreateScriptService("Basic")
        doc = CreateScriptService("Document", bas.ThisDataBaseDocument)
        myForms = doc.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.

### தொடரமைப்பு:

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

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

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

### அளவுருக்கள்:

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.

### எடுத்துக்காட்டு:

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".

##### In Basic

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

##### In Python

        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

### தொடரமைப்பு:

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

### அளவுருக்கள்:

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

### எடுத்துக்காட்டு:

##### In Basic

        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()

##### In Python

        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.

### தொடரமைப்பு:

svc.IsLoaded(formdocument: str): bool

### அளவுருக்கள்:

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

### எடுத்துக்காட்டு:

##### In Basic

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

##### In Python

        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.

### தொடரமைப்பு:

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

### அளவுருக்கள்:

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.

### எடுத்துக்காட்டு:

##### In Basic

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")

##### In Python

        doc.OpenFormDocument("myFormDocument")

        doc.OpenFormDocument("myFolder/myFormDocument")

## PrintOut

This method sends the content of the given form document to a default printer or a printer defined by the SetPrinter() method.

Returns True if the document was successfully printed.

### தொடரமைப்பு:

svc.PrintOut(opt formdocument: str, pages: str = "", copies: num = 1): bool

### அளவுருக்கள்:

formdocument: A valid document form name as a case-sensitive string. The form document must be open. It is activated by the method.

pages: The pages to print as a string, like in the user interface. Example: "1-4;10;15-18". Default is all pages.

copies: The number of copies. Default is 1.

### எடுத்துக்காட்டு:

##### In Basic

        If oDoc.PrintOut("myForm", "1-4;10;15-18", Copies := 2) Then
            ' ...
        End If

##### In Python

        if doc.PrintOut('myForm', copies=3, pages='45-88'):
            # ...

## SetPrinter

Define the printer options for a form document. The form document must be open.

Returns True when successful.

### தொடரமைப்பு:

svc.SetPrinter(opt formdocument: str, opt printer: str, opt orientation: str, paperformat: str): bool

### அளவுருக்கள்:

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

printer: The name of the printer queue where to print to. When absent, the default printer is set.

orientation: Either PORTRAIT or LANDSCAPE. When absent, left unchanged with respect to the printer settings.

paperformat: Specifies the paper format as a string value that can be either A3, A4, A5, LETTER, LEGAL or TABLOID. Left unchanged when absent.

### எடுத்துக்காட்டு:
