(Q) about Dx7 and MsgBox???

Hi Friends
Did any body Show The Game called
(Roller Coaster Tycoon) ???
will it's good game but in it if you want to save mission it give you CommonDialog asking for the Savename and etc
then the game returns back
I want to know (in Dx7) how can I show MsgBox then the game returns back good???

there is some command like "SwitchtoGDISurface" that lets show windows and have window procedures. A little vague, I know, but I hope it helps. Look at the DirectX object, and then the surface objects. I think it is called "FlipToGDISurface"

well Thank you for your help

actualy it's DirctDraw Object NotThe DirectX and not the Surfaces

and it works so good

thank you
