ActiveX programming task overview

About this task

After you generate code with BladeSmith, complete these general tasks to finish your DataBlade® module code:

Procedure

  1. Add code to these source code files to enable your routines to function as you intend:
    • OpaqueCommon.cpp: Contains the logic for the opaque type routines that are implemented both as ActiveX custom methods and server project routines.
    • OpaqueCommon.h: Contains the logic for the IsNull() and SetNullFlag() custom methods.
    • OpaqueServer.cpp: Contains the logic for the opaque type routines that are implemented only for the server project.

    See Implement ActiveX value objects for instructions.

  2. Compile your source code files by using the generated makefiles.
    See Compile client and server projects for instructions.

Results

To avoid merging conflicts when you regenerate your code, add code only in areas marked by Developer: comments or after the generated code. If you do modify code outside the designated areas, you might have two copies of the routine after you regenerate: the one you modified and the one BladeSmith generated. Although your changes remain, you must resolve conflicts in the two pieces of code.
Important: In addition to adding logic to the opaque support routines, you can add your own functions to the C++ classes in the OpaqueCommon, OpaqueClient, and OpaqueServer .cpp and .h files. Do not modify any of the other generated source files.
