Making user defined module available to VB programs using ODBC

[altctldel]

I think there is no REPLACE function in Access 2000.

I had written a module to replace a character in a field and the module name is Repl()

when tried to execute a query with the above method from Visual Basic application,
I got an ODBC Error : Undefined function Repl()

My question is how to execute the query from Visual BAsic Application.
Or
Is there is any Built-In function available to replace a character.
