Usage of the WaterSteamPro in Microsoft Excel

Programming in the Microsoft Excel environment is executed by means of the language Visual Basic for Applications (VBA). The VBA language allows both reference to ActiveX-objects and direct reference to Windows system libraries. Thus there are two ways of "WaterSteamPro" package operation in the Excel environment. The first one - is operation through references to ActiveX-objects of "WSP.WSPCalculator". And the second one - is a direct operation of the "OKAWSP6.DLL" library.

The "WaterSteamPro" package delivery set contains the "WSP_EXCEL.XLS" file with an example of package operation in Microsoft Excel. The given file demonstrates ways of "WaterSteamPro" function access by various programs. The "WSP_EXCEL.XLS" file investigates not all functions but presents examples of water/water steam properties calculation using these functions.

In order to operate with functions for calculation of water and water steam properties directly in Microsoft Excel the user should apply the "OKAWSP6.XLA" add-in. The given add-in is also available in the "WaterSteamPro" package delivery set. Operation technique of the "OKAWSP6.XLA" add-in is presented in the section "The add-in operation in Microsoft Excel".
