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.
This sample code is intended to illustrate a concept, and it shows only the code that is relevant to that concept. It may not meet the security requirements for a specific environment, and it should not be used exactly as shown. We recommend that you add security and error-handling code to make your projects more secure and robust. Microsoft provides this sample code "AS IS" with no warranties.
