Re: how to differentiate a single click from a double click in CTreeviewCtrl

I have no other choice because the request is from a spec defined by my PD colleague. On a single click, an item is selected and I need to do a lot of graphic stuffs that consuming lots of computer power. The PD allow users to double click another item which may not be the one user just select. Because of performance, I don't want to perform the graphic stuffs twice if user double clicks an item.

Then set a status flag in your "graphics stuff" to be, say, "valid" or "invalid".

Set it valid after a single click, and invalid at any time thereafter when another click somewhere would require it to be redone. Then on single clicking act according to the flag.
