Passing An Object’s Property As a Parameter

Why Trust Us

When you pass a read-writable property directly as a ByRef parameter to a function or subroutine, the property will not be changed. This is because in VB 6.0 or previous versions, the parameter will be copied to stack as specified data type, but the object is not referenced. Try the following example:

 Sub Test()    Dim oMyObj As CMyClass    Set oMyObj = New CMyClass    Call GetName(oMyObj.MyName)    ' oMyObj.MyName will be empty string.    Debug.Print
