Simple question about ActiveX controls

Hi

I've created a few activex controls before. I'm now working on a grid control.

There's one thing that puzzles me.

How can a make a public property be available only at run-time?

VB Code:

Public Property Get SomeProp() As Long
 
    If Not Ambient.UserMode Then Err.Raise -60001,Description:="This property not available until run-time"
 
    SomeProp = mSomeProp
 
End Property

Something like that.

:)
