Shell launch with multiple files

Hi

I have my App associated with a file extension and I can launch a file from
explorer and parse the file using Command$ inside the App and that all works
OK.

If I highlicht a bunch of files in explorer and launch then I get separate
instances of my App.

Is there a way of getting all the files sent to the first instance of the
App?

Thanks

Have you tried modifying the registry string associated with your app to
include extra placeholders for files? Something like:

"C:\Program Files\my prog\myapp.exe" "%1" "%2" "%3" "%4"

Hi

After googling a bit I found:
http://www.vbaccelerator.com/home/VB/Code/Libraries/Shell_Projects/Registering_File_Associations/article.asp

Tried the %1 %2 method because the idea is much more elegant than the other
methods but it doesn't want to play ball on my machine!

Thanks

Hmmm, I would guess that you'll have to use App.PrevInstance to determine if
your app is already running and then have the non-first instance of your app
talk to the first and tell it to open the file that was passed to this
current instance (and then shut itself down).

Thanks

Did this and sent the filename using UDP to the main instance using
localhost.
