procedureexists(
DATABASE
,
PROCEDURE
)
The procedureexists( function checks to see whether a procedure exists or not.
Parameters
This function has two parameters:
database – The database that contains the procedure you want information about, or "" for the current database (or can be omitted entirely).
procedure – The name of the procedure you want to check for existence.
Description
This function checks to see whether a procedure exists or not. This function works even if the code author does not have the authorization to examine the database structure (so they cannot see a list of procedures).
Here is a simple exmple that checks to see if an .IntializeMenu procedure exists, and if so, calls it.
if procedureexixts(".InitializeMenu")
call .InitializeMenu
dndif
This function can also be used to check if a procedure exists in another open database.
if procedureexists("Contacta","dialphone")
farcall "Contacts","dialphone","555-1212"
endif
Note that if the Contacts database isn’t open, this code will stop with an error. A well placed catcherror( function can cure that problem.
if catcherror(false(),procedureexists("Contacta","dialphone"))
farcall "Contacts","dialphone","555-1212"
endif
This code will not fail even if the Contacts database is not open.
