Can anyone help me complete with this API declaration?

Code:
Declare Function rtcCallByName Lib "Msvbvm60.dll"
(AClass As Variant, 
 Procedure As String, 
 Something As Long) As Long
As you see I am trying to use an API call to VB6's CallByName to use it with VB5 and/or VBA. The declaration function as it is, crashes when I call it. I am not quite sure of the declaration types of CallByName. Anyone with VB6 can see the types when they fill in the parameters, but I don't have VB6. Can anyone help me solve this?
