MFCCALC Sample: Demonstrates an Automation Server Application

The MFCCALC sample is an Automation (formerly OLE Automation) server. It implements a simple calculator similar to the CALC application in Windows. It can be driven with Automation with the CALCDRIV sample or run stand alone.

For more information, see the CALCDRIV sample.
