Command PV OPEN DOCUMENT

PV OPEN DOCUMENT

version 6.8

PV OPEN DOCUMENT (area; document; template)

Parameter	Type		Description
area	Longint		4D View area
document	String		Document name
template	Integer		0 = Document; 1 = Template

The PV OPEN DOCUMENT command opens in area the requested document.

Pass in document the full path name of the document to open. If you pass an empty string ("") in this parameter, a standard open file dialog box appears and the user can select the document. If the user clicks Cancel in this case, no document will be opened.

The template parameter allows you to set whether the document should be opened as a standard document (template=0) or as a template (template=1).

When a document is opened as a template, a new document "Untitled" is actually created, containing a copy of the requested document. The original document remains intact.

If the value of template is 1, the document is opened as if it were a template regardless of its actual status (document or template), set by PV SAVE DOCUMENT.

Note: The "document" template mechanism is managed by the OS. It is different from the one used with 4D View "templates", attached to included areas (accessible using the Save as template menu command). For more information on area templates, refer to the 4D View User manual.

Open a standard open file dialog box, applied to 4D View:

   PV OPEN DOCUMENT (Area;"";0)  `Document choice

PV SAVE DOCUMENT.

The Document variable system contains either the name or the access path and the name of the last disk file opened (see the 4D Language Reference manual, System Variables section).

The system variable OK uses 1 as its value if the document was correctly opened.
