[Openroad-users] Word ActiveX (again!) - External Class Events

Tue Jul 8 21:04:23 EST 2008

I've seen this before - the names are ok, but the parameters are passed
in the wrong order.
I think there should be a bug fix available.

trying that produced this error:

E_WT0029 Error at line 27 of main_go.

E_WR0003 Value passed to parameter of incompatible type.
    A value of type '_document' was passed to the parameter 'cancel' in
the
    frame 'main_go'.  The type '_document' is not compatible with the
type
    of the parameter, 'i4'.

E_AF2001_NO_CONVERSION Object can not be converted to i4.
E_WR006C Error assigning a value to parameter 'doc'.

E_OM000B A non-object typed value passed to an object.
    A value whose type is not a class was passed to a parameter that is
an
    object.

This seemed to suggest incorrect naming of parameters, having swapped
them around, all is ok!?

So my code is now:

ON EXTCLASSEVENT 'DocumentBeforeClose' (cancel = WinWord!Document
DEFAULT NULL,doc = INTEGER NOT NULL)=
BEGIN

    IF cancel IS NOT NULL THEN

        CurFrame.Trace ( text = 'closing:' + VARCHAR(cancel.Name) );

    ENDIF;

END;

I guess there is something wrong in the OR interface to the ActiveX?

	The definition of the COM event shows 2 parameters, but you only
specified one of them.
	In addition, the parameter names do not match - it has to be
"doc" rather than "doc_closing".

	Try:

	ON EXTCLASSEVENT 'DocumentBeforeClose' (doc = WinWord!Document
DEFAULT NULL, cancel = INTEGER NOT NULL)=
	...

	thanks to Ian & Bodo for the same idea, whilst it does stop a
new blank document opening, due to doc_closing now being NULL, this
parameter really should have the closing document in it.  I noticed my
trace message was actually reporting the name of the newly opened blank
document and not the one that was closing down ... the closing document
reference is obviously not coming back?

	here is the Microsoft definition:

		Have you tried declaring the "doc_closing" parameter
with DEFAULT NULL?

		I'm working in OR4.1 SP3, as External Class Events in
OR2006 are not working correctly, so whilst I wait for a fix ... 

		I want to know what document is closing, so I trap the
external class event as follows: 

		ON EXTCLASSEVENT 'DocumentBeforeClose' (doc_closing =
WinWord!Document)= 
		BEGIN 

		CurFrame.Trace ( text = 'closing:' +
VARCHAR(doc_closing.Name) ); 

		END; 

		Now this works in the sense, in that it reports the
document name closing, however it seems the declaration in the parameter
list of 'WinWord!Document' actually initiates a new document to be
opened/created ... not quite what I was expecting 

		is this a bug, and is there away around it? I've tried
having the parameter as type ExtClass but that was of no use.
