Passing report listener between forms - VFP9

[DeCiacco]

I can't seem to figure out how to pass a report lister object to a form. The calling
form has the data needed for the report to run. I want to created the listener of
type 3, run my report to object and then pass it to my pop up form for display.

Thanks.

What have you tried so far? Did you get error messages?

Thanks for your reply.

I've been able to figure it out. I simply did a Do Form <formname> WITH <objectname>
and the init event of my form accepts the object. I just got confused because
<objectname> is really a pointer to the object and that's the only thing that gets
passed instead of the actual object.

That's the way objects are passed in Foxpro, to variables, to properties, to
parameters. Only the pointer to the object is copied. But this pointer is enough
to access the object.
Also in a line like this:
loOtherObject = loSomeObject
only the pointer from loSomeObject is assigned to loOtherObject, never a copy of
the object! Both variables reference the same object. If you lateron change a
property of loSomeObject, you see the new value in loOtherObject.

Do you store your object reference to a custom form property(good) in the
init or make your variable public(bad)?

When the init finishes all it's variables go out of scope.

Custom form property....
But I don't do that anymore as I use the default datasession due to a problem i've
been having with the "Report Form <rptname> Object" command not allowing the
datasession to release if issued more than one time.

Check this newsgroup for "Form session not being released when nopageeject used -
VFP9", make sure to take a look at the updates as I discovered more info on the problem.

Thanks!
