[cfaussie] Re: cfexecute problem...

[gary menzel]

So... I was right with my reply to Andrew (who is also having CFEXECUTE problems).

Interestingly enough, the Cold Fusion Manual (yes, those paper things that have also made their way into our computers as slabs of HTML) clearly states how the ARGUMENTS parameter is parsed and used.....

You can pass a string or an array.

If it's a string - then under Windows it just passes the string on to the application (in the case of a C/C++ app - this will be parsed into argv/argc).  Under Unix/Linux it is parsed into and array of arguments (separator is a space using normal Unix command line parsing rules).

If it's an aray - then under Windows they are all concatenated back into a string!!! (duh!!! - they could have used the exec api as they are doing in Unix).  In Unix/Linux the array is copied into the arguments of the exec() call.

So - there you have it - and it's in black and white too - page 83 in my book.

I don't often rant like I am about to - but.......

<rant>
Why do people automatically just jump onto a list at the slightest sign of trouble?  What ever happened to the pride of tracking down a problem by searching through the documentation?  And then, when all hope was lost, firing up a browser and searching for all manner of things - probablly through Google - to see if there were any answers already out there?  But no - these days we just seem to throw a query onto the list - even when half the syntax of what we are trying to do is not "kosher" within what we are trying to do!!!

You know - I rather have Scott's "off topic" raves!!!
</rant>

Geee - I must have woken up on the wrong side of the pool this morning!!
