Pass string and long array from VB ActiveX to VC++ ?

[marwic]

I have written a VB ActiveX control. I use this control in a dialog based
VC++ MFC application.
How can a string and a long array be passed from the VB ActiveX control
to the MFC application.

How to declare in VB ActiveX control?
public Sub GetString(Text as ??)
End Sub

public Sub GetLongArray(LongData as ??)
End Sub



..and how to call and get in VC++ MFC application?
?? Text;
m_MyControl.GetString( Text );

?? LongData;
m_MyControl.GetLongArray( LongData );



Any help appreciated ;-)
