When you implement an Interface in your Class the arguments are automatically named RHS as shown on MDSN https://msdn.microsoft.com/en-us/library/office/gg264387.aspx
For example, if I create IInterface as so:
Public Property Let Value1(strValue1 As String)
End Property
Public Property Let Value2(strValue2 As String)
End Property
And implement it, the class would look like this:
Implements IInterface
Private Property Let IInterface_Value1(RHS As String)
End Property
Private Property Let IInterface_Value2(RHS As String)
End Property
It's a best practice to name your arguments in such a way as to provide some level of abstraction and make it easier to read and write code. I can actually change the arguments to whatever I want in the class after I've implemented the statements, as shown below, but my question is why does this happen? Is RHS a leftover from another language or is there a particular reason it's named like this?
Implements IInterface
Private Property Let IInterface_Value1(strValue1 As String)
End Property
Private Property Let IInterface_Value2(strValue2 As String)
End Property
The above compiles fine if I manually change it.
rhs stands for right hand side of operator = and lhs for left hand side of =. Why is this named like this here? Maybe its something which comes from c++ conventions. By the properties you have consider this code:
Dim test As IInterface
Set test = New ClassTest
test.Value1 = "rhsVal"
The new string value is actually on the right side of the = so therefor rhs.
