Opening custom files by Drag and Drop in standalone application

[Alejandro Tejada]

Hi Developers,

Before sending an attachment to bugzilla,
i want to recap the whole issue, for your
additions, confirmations and corrections:

Begin Report

Problem:
When i drag and drop a Rev or MC stack to a
Windows standalone i had created, it opens the
application and the stack dropped over
the executable.

Workaround:
(posted by Frank D. Engels jr.)
Under Windows, you would need to check 
the $1 variable when starting
the standalone, if a stack is
specified, close it right away, 
display an error message, and quit.

(code tested by Alejandro Tejada)

-- use this code in the card script
-- of the first card in the mainstack
-- of the standalone executable

on startup
lock messages 
-- by locking messages, you
-- do not give permission to dropped stacks
-- to execute any script...

if $1 is not empty
then
answer "Please, open this application by double
clicking it's shorcut or the executable file and then
drag and drop your file inside the application's open 
window or click the Open file button within the 
application window."
quit
end if

end startup

Problems of this workaround:
(Ken Ray)
The problem is that the document stack always 
displays before you can do anything about it, 
so it looks funky.

(Alejandro Tejada)
And your file association are rendered
useless, because when you double click
on a document associated to your standalone
application, you trigguer this startup handler
and your application only shows a message and close.

What additional information needs this report?

Honestly, i don't know... but in Windows
if i drop a stack over any executable created 
with MC or RR, the stack opens and the application 
is launched.

I'll give it a try. :-)
