Invalid ordinal (Error 452)

Your call to a dynamic-link library (DLL) indicated to use a number instead of a procedure name, using the #num syntax. This error has the following causes and solutions:

• An attempt to convert the num expression to an ordinal failed.

  Make sure the expression represents a valid number or call the procedure by name.

• The num specified doesn't specify any function in the DLL.

  Make sure num identifies a valid function in the DLL.

• A type library has an invalid declaration resulting in internal use of an invalid ordinal number.

  Comment out code to isolate the procedure call causing the problem. Write a Declare statement for the procedure and report the problem to the type library vendor.
