Open several custom extension files selected in single application

Hi Techies,


During my application installation I am setting registry entry to open our
custom file extension ".tes" in our application "testapp.exe"

..tes <Default> REG_SZ teststart

teststart
Shell
Open
Command <Default> REG_SZ
"C:\\test\testapp.exe" "%1"




When several files of ".tes" are selected and clicked open, this tries to
open each file in each instance of our application. I would like all to open
in a single application. How can I achieve this by adding registry entry.
Please tell me the complete procedure. Should this be used as
"REG_MULTI_SZ"??


Regards,
Karthik.

You can try using "%*" instead of %1 (the first delimited argument
passed) but that may not work. The application expects and handles
what from the commandline? If it cannot accept multiple fully
qualified paths or dbl-quoted fully qualified paths, then the
application needs to be modified.

No, REG_MULTI_SZ does not appear to be any solution.

What happens if you, (all one line) specify multiple fully
qualified paths to your application from a CMD session? I will
guess your app only "sees" the first one. Many unknowns from here
but perhaps that will help you pin down the problem.
