How do I make a timer work in c++ WM_PAINT? I'm trying to "print" it via Wm_Paint, because at the moment I don't know another method of adding a timer, googling didn't help.
Here's what I have declared in CALLBACK
:
TCHAR s[10], str[20] = _T("Seconds: ");
static int t;
case WM_CREATE:
SetTimer(hwnd, 1, 1000, NULL);
And here's how I try to draw the timer:
hdc = BeginPaint(hwnd, &ps);
hBrush = CreateSolidBrush(g_color);
hPen = CreatePen(PS_NULL, 1, RGB(0, 0, 0));
holdPen = HPEN(SelectObject(hdc, hPen));
holdBrush = (HBRUSH)SelectObject(hdc, hBrush);
_tcscat(str + 9, _itot(t, s, 10));
TextOut(hdc, 10, 300, str, _tcsclen(str));
SelectObject(hdc, holdBrush);
SelectObject(hdc, holdPen);
DeleteObject(hPen);
DeleteObject(hBrush);
EndPaint(hwnd, &ps);
So far, it just prints out "Seconds: 0" and stops updating.
Ok so, for me to make it work, I've had to create a
WM_TIMER
case in myCALLBACK
function, in the end it looked like this:
