SftMask/DLL 7.0 - Masked Edit Control

DateTime Sample (C++/MFC)

This sample illustrates date input with a dropdown calendar (defaulting to today's date using the =Today default text) and date/time input with up-down buttons, hosted in an MFC dialog through CSftMask and DDX_Control.

The source code is located at C:\Program Files (x86)\Softelvdm\SftMask DLL 7.0\Samples\MFC\DateTime or C:\Program Files\Softelvdm\SftMask DLL 7.0\Samples\MFC\DateTime (on 32-bit Windows versions).
