DSWaitForFile with '*'

Hola mis amigos.....

I'm trying to execute a DSWaitForFile with something like *.TXT as parameter to the function.

Is this possible ? Is there any special hint to take into account to have this working ?

Thanks in advance.

Not possible, the stage does not support wildcards.

Dang site is acting up for me today. Push the button once, wait forever and then get two posts for the price of one. Sheesh.

As Craig says (says), the Wait For File activity does not support wildcards. However, such a routine would be easy to write, and could be invoked from a Routine activity.

In a loop, execute an operating system command to list whatever the wildcard refers to, and to return if the number of items listed is more than zero. Include a short SLEEP (or a NAP) in the loop so that the routine does not become a CPU hog, and handle the timeout sensibly.
