Hi all

I use the following code from the wiki to launch the default web
browser on Windows XP

catch {eval exec [auto_execok start] [list $url] &} err

and this works fine when my code is executed from the command line e.g
tclsh85 myprog.tcl.

However when I wrap the application into a .exe using TclApp (from
tclDevKit) all I get is a Windows command window the browser isn't
launched. The same problem occurs if I create a .kit instead of
the .exe.

The url being launched is a file on the disk external to the VFS in
the kit.

As ever all help gratefully recieved

kind regards

Does [auto_execok start] return the same thing?

In all cases (.kit, .exe & .tcl) auto_execok start returns C:/WINDOWS/
system32/cmd.exe /c start

Hi Julian,

To launch the default browser on Windows I do that:

set url [regsub -all -nocase {htm} $url {ht%6D}]
exec rundll32 url.dll,FileProtocolHandler $url &

Ok, so then we have the refined question, "Why does [exec
C:/WINDOWS/system32/cmd.exe /c start $url &] have
different behavior in the different contexts?" Test and confirm that's
the root issue.
