How to know when an Ole Object can be Destroyed - Word Doc

How to know when an Ole Object can be Destroyed - Word Doc

How to know when an Ole Object can be Destroyed - Word Doc

PB 12.6
I have an OLE Object being used to open a Word Document for the user to view. The issue that I have is that I do not know when or if the user closes the session of Word that gets launched so am not sure how to handle Destroying the object.

I appreciate any comments, examples, recommendations on how to handle this situation.

code snippet
at this point, the word document file name is stored in string variable ls_doc_file

// Declare local Ole Word Doc Object
OLEObject ole_obj_word_doc

// instantiate the ole object
ole_obj_word_doc = CREATE oleobject

// connect to WORD app
li_retval = ole_obj_word_doc.ConnectToNewObject("word.application")
IF li_retval < 0 THEN
DESTROY ole_obj_word_doc
MessageBox("Connecting to COM Object Failed", &
"Error: " + String(li_retval))

// open the file

// Make the object visible and display the
ole_obj_word_doc.Application.Visible = True

// *********************************************
// These are commented out because I don't know
// when the user closes the file.
// *********************************************
// shut down the server
// destroy the object
//??DESTROY ole_obj_word_doc
// *********************************************

RE: How to know when an Ole Object can be Destroyed - Word Doc

You won't ever know when/if the user closes the word doc. About the only thing you can do is to issue a DisconnectObject command when the window/application closes. I wouldn't worry about using DESTROY as the garbage collection will take care of this.
