Using ActiveX Value Objects

Follow the Microsoft guidelines on how to invoke COM and automation objects.

If you are using the IBM Informix ESQL/C client API, it is recommended that you write the application in C++ and place only the SQL-specific code in the .ec files through embedded C code.

If you are using Visual Basic, you must cast the Informix lvarchar data type to char before you can work with ActiveX value objects.

Important:

As you use ActiveX value objects, keep in mind that object persistence between server and client objects is not supported. In other words, although you can modify an ActiveX value object, an associated modification does not occur to the database data represented by that object unless you issue an SQL query.
