Now using a TimerProc.
VOID CALLBACK TimerProc(
HWND hwnd, // handle of window for timer messages
UINT uMsg, // WM_TIMER message
UINT idEvent, // timer identifier
DWORD dwTime // current system time
);
It is called by the system to process an associated Timer's WM_TIMER message. Let's see some code.
#define IDT_TIMER1 1001
...
/* The Timer Procedure */
VOID CALLBACK TimerProc(HWND hwnd,
UINT uMsg,
UINT idEvent,
DWORD dwTime)
MessageBox(NULL, "One second is passed, the timer procedure is called, killing the timer", "Timer Procedure", MB_OK);
KillTimer(hwnd, idEvent);
...
/* Creating the timer */
SetTimer(hwnd, IDT_TIMER1, 1000, (TIMERPROC)TimerProc);
...
How do I obtain IDT_TIMER1 in the TimerProc? the idEvent doesn't match this value and uMsg is always 0x110 (WM_TIMER), is it encoded somehow because the idEvent is like 0x739B while IDT_TIMER1 is 1001 (0x3E9)

Your code is simply incorrect. The definition of TimerProc (msdn.microsoft.com/en-us/windows/desktop/ms644907) is different than yours.

Figured out from documentation.
idEvent - Specifies a nonzero timer identifier. If the `hWnd` parameter is NULL, this parameter is ignored.
so it's getting ignored.
Fixed it like this
#define IDT_TIMER_1 1001
UINT_PTR Timer1IdEvent;
Timer1IdEvent = SetTimer(hwnd, IDT_TIMER1, 1000, (TIMERPROC)TimerProc);
...
VOID CALLBACK TimerProc(HWND hwnd,
UINT uMsg,
UINT idEvent,
DWORD dwTime)
if( Timer1IdEvent == idEvent)
MessageBox(NULL, "One second is passed, the timer procedure is called, killing the timer", "Timer Procedure", MB_OK);
KillTimer(hwnd, idEvent);
