Jon,
RunThrough does work under Windows 95/NT, but there are a few things you
need to observe. It appears that RunThrough does not handle long file names
correctly, particularly if the path to the application you want to execute
contains spaces. So the following command will probably not work on your
system:
RunThrough[
"C:\\Program Files\\Wolfram Research\\Mathematica\\3.0\\myapp.exe",
""
]
The reason seems to be that Mathematica interprets this command as
RunThrough["C:\\Program" ...]
with arguments "Files\\Wolfram" and "Research\\Mathematica\\3.0\\myapp.exe".
To avoid this problem, move your external applications to a directory with a
short name, say "C:\\extapps", and call your executable with
RunThrough["C:\\extapps\\myapp.exe", ""]
Alternatively, you can add your application path to your system's PATH
variable. Then,
RunThrough["myapp.exe", ""]
should do the job.
Best regards,
Eckhard
