Awhile ago I wrote a Connect 4esque program. I had to handle mouse selections.

I don''t know much about Direct3D, but I''ll assume that you still get all of the regular windows messages.

I''m not sure if this will help you but:

Every time something happens you''ll get a message from windows. In the case of a mouse click you''ll get WM_LBUTTONDOWN. The event data will include the mouse coordinates.

Check to see if these coordinates are on top of on of your ''items''. In a board game, this is usually really easy because the ''board'' is broken up in to logical regions.

This mouse down will ''SELECT'' the selection, but not activate it. To demonstrate this, move the mouse over a button in your web browser, then hold the mouse button down. The button becomes depressed, but no action is taken.

So you remember what item was selected, and then wait for a WM_LBUTTONUP event. Check the coordinates from the message, and if they''re in the same object as the WM_LBUTTONDOWN event, you assume the user wants to activate the control. This could mean anything, depending on your program.

You can probably find tons of code out there that uses this model.

Hope this helped.
