ParamArray help needed

$

0

I have wrapper methods for database calls, so I can handle and more particularly log errors, and not have to pad out the main logic for every database call. So, for ExecuteSQL, I might have this:

dbexec (Extends dbh as sqlitedatabase, sql as string, ParamArray args as Variant) as Boolean
try
  dbh.ExecuteSQL (sql, args)
  Return True                      // Worked fine, just return
Catch e as DatabaseException
  dblogargs (args)                 // Log argument values here
end try

.
What I want to do in dblogargs is to pick out the args which are integers, and log only those, so I might end up with a message in the log file something like:

arg0=27, arg3=5, arg4=7

(in this picture, I skip arg1 and arg2 because they are strings)

Where I’m getting into trouble is getting the type of each element of args, the ParamArray. If I look at VarType(arg) or arg.Type(), then each arg appears to be type 9 (Object). And if I have an arg that I know to be an integer, then something like:

Var  i as Integer = arg.IntegerValue

just gives me a TypeMismatchException. How do I get at the integer that must be hidden in there somehow?
