How to get the progress of a timer made with SetTimer() - c++

Question

Is there any way to get the current progress of a timer, which is created by the SetTimer function?

Answer 1

Here's an implementation of Hans' comment. Clicking the button shows the time remaining until the next scheduled (expected) WM_TIMER message. By building in debug mode, I get a console to display my messages, since it's such a quick and easy (read: dirty) way of getting both a GUI and a console.
main.cpp
#include <windows.h>
#include <commctrl.h>
#include <stdio.h>
#include "resource.h"
HINSTANCE hInst;
DWORD tickCountInitial;
DWORD timerInterval = 10000;
DWORD nextTimerFired;
BOOL CALLBACK DlgMain(HWND hwndDlg, UINT uMsg, WPARAM wParam, LPARAM lParam)
{
switch(uMsg)
{
case WM_INITDIALOG:
{
tickCountInitial = GetTickCount();
SetTimer(hwndDlg, 666, timerInterval, NULL);
nextTimerFired = tickCountInitial + timerInterval;
}
return TRUE;
case WM_TIMER:
{
DWORD tickCountCurrent = GetTickCount();
printf("Ticks elapsed: %d\n", tickCountCurrent - tickCountInitial);
nextTimerFired = tickCountCurrent + timerInterval;
MessageBeep(MB_OK);
}
return 0;
case WM_CLOSE:
{
EndDialog(hwndDlg, 0);
}
return TRUE;
case WM_COMMAND:
{
switch(LOWORD(wParam))
{
case IDC_BUTTON1:
{
DWORD tickCountCurrent = GetTickCount();
printf("Ticks till next WM_TIMER message: %d\n", nextTimerFired - tickCountCurrent);
}
break;
}
}
return TRUE;
}
return FALSE;
}
int APIENTRY WinMain(HINSTANCE hInstance, HINSTANCE hPrevInstance, LPSTR lpCmdLine, int nShowCmd)
{
hInst=hInstance;
InitCommonControls();
return DialogBox(hInst, MAKEINTRESOURCE(DLG_MAIN), NULL, (DLGPROC)DlgMain);
}
