NOTE
・If the operating system is a 64-bit version, those DLLs can be linked into only
64-bit applications.
32-bit applications cannot use those DLLs.
The following functions have been provided to maintain backward
compatibility with Windows NT® programs and old equipment, but 64-bit

・Do not copy or move w2kras.dll, hfwras.dll, hfwraid.dll, and ctrl7seg.dll to
another directory. If you do, the RAS feature of this equipment cannot run
properly.
The functions offered by w2kras.dll and ctrl7seg.dll can be called from Visual Basic®
(.NET is required for 64-bit operating systems). When you call functions number 1
through 7, 9, and 13 through 15 from Visual Basic®, add "_VB" to the end of the name
of each function. Function parameters are the same. For example, when you call the
WdtControl function from Visual Basic®, use the function name "WdtControl_VB".
The following files are provided as import libraries:
%ProgramFiles%\HFWRAS\lib\w2kras.lib
%ProgramFiles%\HFWRAS\lib\hfwras.lib
%ProgramFiles%\HFWRAS\lib\ctrl7seg.lib
%ProgramFiles%\HFWRAS\lib\hfwraid.lib
When you use a library, link the corresponding import library.
