Most code samples included on this CD were developed with Microsoft Visual C++ version 5.0 and the Microsoft Windows CE Toolkit for Visual C++ version 5.0. The Sspi and Crypto samples were developed with Microsoft Visual C++ version 6.0 and the Microsoft Windows CE Toolkit for Visual C++ 6.0. The code in sample applications is ported for a Handheld PC, but the programming concepts that are presented apply to all Windows CE-based platforms. -Most code samples included on this CD were d eveloped with Microsoft Visual C version 5.0 an d the Microsoft Windows CE Toolkit for Visual C v ersion 5.0.
