    Some spammers sign up to CC and then they leave their account hidden so they think it won't get noticed but with an obvious name like "SaxophoneRetailSingapore" it's hard not to know they are a spam bot. #ModLife

    Programming is something that I enjoy and want to make a career out of. But, I usually tend to start things and not finish them. Any advice on how I can finish what I start?

In Windows, users may swapped mouse button to make physical right button to be considered as left button, and vice versa. This feature is to support left-handled people. And if you need to detect this possibility (like after you detect a mouse button is pressed, like in this code snippet), you can use the following code.

 

uses
  ...
  , Windows
  ...
  ;

(* This function returns true if the mouse buttons are swapped *)
function IsMouseBtnSwapped: Boolean;
begin
  Result := GetSystemMetrics(SM_SWAPBUTTON) <> 0;
end;
