If you are coding and using
<cfexecute /> then don’t forget the
<cfexecute name="#exe#" variable="cmdLineOutput" errorVariable="errData" timeout="60" />
Without it the code will just file off the command line call to execute your
.exe without waiting for a response.
Don’t worry about making it too long: if you use a timeout of, say, 60 seconds your call will return if it finishes quicker than that.
