Windows cannot open this file: foo.BAR

[woodBeeProgrammer]

CONTEXT ok, so if i register the file extension .bar
Windows is happy and when a user double clicks myApp gets
called. but if the user double clicks my data file
BEFORE i get to register, the user gets: Windows cannot
open this file: FOO.bar. To open this file, Windows
needs to know what program created it..
--OR-- Use the Web service
--OR-- Select the program from a list

QUESTION: is there any way (such as including
information about myApp in the file itself) to let the
user know that they need to INSTALL myApp in order to
open FOO.bar?

Thanks in advance!

Hi,

I'm afraid no. Unless you register the file type, Windows will be displaying
the standard dialog box prompting the user to choose a program.
