C++ language
The Informix® DataBlade Developers Kit (DBDK) currently allows you to write opaque data type support routines in C++.
You can also create ActiveX value objects to represent opaque data types on a client computer. If you want to include other database objects in your DataBlade module, the DataBlade Developers Kit allows you to code them in C or Java™.
The C++ support routines use DataBlade API routines
to process opaque data types in the database server. For more information
about the DataBlade API,
see the IBM® Informix DataBlade API Programmer's Guide.
Important: It is recommended that developers create DataBlade modules
in C++ only for client projects and for server projects that use Informix on Windows only.
