enumeration
Properties and arguments of this type have a predefined list of possible values beginning with the letters "rc." You can use one of the "rc" values or the equivalent number (referenced in Rwinapi.txt).
In returning an enumeration value to a program, Reflection always returns a number. Use If...Then...Else statements to test for the value:
Dim integerValue As Integer
integerValue = Session.BlockTransferUnit
If integerValue = rcPage Then
Use an integer variable to hold an enumeration value.
