CYDAS UDR Library User’s Guide CYDAS UDR Library for .NET Description & Use

MccService class

The MccService class contains all members for calling utility UDR Library functions. This class contains

nine static methods (you do not need to create an instance of the

MccService class to call these methods):

 DeclareRevision()

 WinArrayToBuf()

 ErrHandling()

 WinBufToArray()

 GetRevision()

 WinBufAlloc()

 FileGetInfo()

 WinBufFree()

 FileRead()

The following code examples demonstrate how to call a UDR Library for .NET memory management method

from within a CYDAS UDR Library program:

WindowHandle=MccService.WinBuffAlloc(1000)

MccService.WinBuffFree(WindowHandle)

GlobalConfig class

The GlobalConfig class contains all of the members for getting global configuration information. This class

contains three properties:

 MccDaq.GlobalConfig.NumBoards property returns the maximum number of boards that you can install

at one time.

ConfigGlobal=MccDaq.GlobalConfig.NumBoards

 MccDaq.GlobalConfig.NumExpBoards property returns the maximum number of expansions boards that

are allowed to be installed on the board.

ConfigGlobal=MccDaq.GlobalConfig.NumExpBoards

 MccDaq.GlobalConfig.Version property is used to determine compatibility with the library version.

ConfigGlobal=MccDaq.GlobalConfig.Version

Each of these properties is typed as an Integer.

MccDaq enumerations

The MccDaq Namespace contains enumerated values which are used by many of the methods available from

the MccDaq classes (see Table 5-1). Refer to specific method descriptions in the CYDAS UDR Library

Function Reference for the values of each enumerated type. This document is available on our website, on this

software CD, and C:\MCC\Documents (by default) after software is installed.

Table 5-1. MccDaq Enumerated Values

Enumeration Name Description

MccDaq.BCDMode Lists all of the counting format options.

MccDaq.C8254Mode Lists all of the operating modes for 8254 counters.

MccDaq.CompareValue List all options for comparing values while configuring a 9513 counter.

MccDaq.ConnectionPin

Defines the connector pins to associate with the signal type and direction when
