Supports most Windows C/C++ compilers (Microsoft (all versions Visual C++, C#, and .NET), Borland, Watcom, LCC-WIN32, etc.). Can be used with Microsoft Foundation Class and Borland C++ Builder programs. Does not depend on support libraries. Makes calls to Windows API functions only. Can also use with Delphi, Visual Basic (VB.NET), PowerBASIC, Visual FoxPro, Visual dBase, Xbase++, and COBOL. Can be ordered with or without source code for the DLL.
