running an executable from a perl cgi

[stfaprc]

We are in the midst of attempting to get a perl script to run an executable when it is running via a browser.

we have tried system() and open (IN,"|-") || exec

in both cases we get an error message about being unable to spawn cmd.exe (this is running on IIS4) .
When I put the executable in the cgi-bin directory,
the exe will start but that is all it does. The only way that I know it started is that it shows in the 'Task Manager', where it stays until reboot since I can't terminate it.

I normally use backticks if you are wanting it to block (wait till it is done executing to continue)..

Like


$output = `c:/test.exe`;
print "Output from script is $output\n";

ok, that seems to have stopped the problem of the exe staying in memory. but it still did not actually run,
still have the error that cmd.exe can not spawn.

check that you are passing the full path to you output.

I.e. don't pass `test.pl` but `/path/to/file/test.pl`;
