    Using Predefined Constants
    In This Topic

    InfoConnect frequently uses predefined constants in place of numbers to make macros easier to read. Predefined constants may be used as method arguments, property values, or error codes.

    The last two lines in the following example show equivalent ways to handle errors in IBM sessions. The first statement uses an InfoConnect predefined constant, and the second statement uses the numeric equivalent:

    Using a predefined constant
    Copy Code
    Dim ret As ReturnCode
    ret=ThisIbmScreen.WaitForHostSett(6000, 3000)
    If ret = ReturnCode.ReturnCode_Timeout Then MsgBox "Time out"
    If ret = 4 Then MsgBox "Time out"
    

    Using Predefined Constants in Other Applications

    You can use InfoConnect predefined constants in other applications by selecting the InfoConnect class libraries.

    1. In the Visual Basic Editor, choose Tools > References.
    2. Select the Reflection class libraries:

      Attachmate_Reflection_Objects_Framework

      Attachmate_Reflection_Objects

      Attachmate_Reflection_Objects_Emulation_IbmHosts

      Attachmate_Reflection_Objects_Emulation_OpenSystems

    3. To use legacy predefined constants in other applications, select the appropriate class library.
