The ActiveX Server capabilities of WAFERMAP are quite extensive. WAFERMAP functions (methods) can be called directly from other programs. WAFERMAP can be used in the background as an ActiveX server to do specific tasks for the custom application.
For example:

- Run the custom application.
- Run WAFERMAP in the minimized mode. It will not be used directly, but it must run in the background.
- The custom application then calls the WAFERMAP function to draw a 2D colored plot into a picture box that has been defined within the custom application.

The following picture illustrates the methodology:

WAFERMAP can be used in this mode to provide not only plotting capabilities (this is presently implemented), but also other features like file operations, analysis, SPC, etc. Discussions with customers will determine what additional ActiveX server features are available.
