Subject RE: Problems with exec task

Actually, wscript.exe is usually associated with Windows scripting
languages. I suggested cscript.exe because it is more appropriate for
console usage. Wscript.exe displays debug and echo messages in dialog
boxes. Cscript.exe displays messages as text.

BTW, this is a Windows thing and doesn't have much to do with ant.

The command line is special. There is an ENV varialble, PATHEXT which 
declares which things to start, using ::ShellExecute , which does the 
mapping from file ext to program, and runs the program with the program 
passed in. If you add something like .mp3 to PATHEXT, then all you need 
to do is type in the name of your mp3 file and will autorun in winamp or

other chosen player.

1. look up the binding in the registry to find out which app gets run 
next to .vbs. I dont know what it is, but you need to recreate the 
command line.

2. I have an exe , "open.exe" that takes any file arg and hands it off 
to ShellExecute. I can email it to you if you like, though its only 
about three lines of code, something like

#include "shell32.h"

void main(char*[] argv) {
 
::ShellExecute(NULL,"open",argv[1],NULL,::GetCurrentDirectory(),SW_SHOWD
EFAULT);

}

file binding for VBS is, unless changed (I normally bind it to notepad 
for security reasons):

C:\WINDOWS\System32\WScript.exe "%1" %*

I wouldnt use the spawn option; all output gets dropped.

its an shell integration problem, which is something java itself is weak

on. There is a limit to what ant can do with the minimal underpinnings, 
but as a reward we dont have to worry about windows internals, or care 
about what win vista is going to do with unsigned binaries.
