1.1 用WM_TIMER来设置定时器
先请看SetTimer这个API函数的原型
UINT_PTR SetTimer(
HWND hWnd, // 窗口句柄
UINT_PTR nIDEvent, // 定时器ID,多个定时器时,可以通过该ID判断是哪个定时器
UINT uElapse, // 时间间隔,单位为毫秒
TIMERPROC lpTimerFunc // 回调函数
);
void CTimerTestDlg::OnTimer(UINT nIDEvent)
{
switch (nIDEvent)
{
case 24: ///处理ID为24的定时器
Draw1();
break;
case 25: ///处理ID为25的定时器
Draw2();
break;
}
CDialog::OnTimer(nIDEvent);
}
void CALLBACK TimerProc(HWND hWnd,UINT nMsg,UINT nTimerid,DWORD dwTime)
{
switch(nTimerid)
{
case 1: ///处理ID为1的定时器
Do1();
break;
case 2: ///处理ID为2的定时器
Do2();
break;
}
}
BOOL KillTimer(
HWND hWnd, // 窗口句柄
UINT_PTR uIDEvent // ID
);
#include
#include
VOID CALLBACK TimerProc(HWND hwnd,UINT uMsg,UINT idEvent,DWORD dwTime);
VOID CALLBACK TimerProc(HWND hwnd,UINT uMsg,UINT idEvent,DWORD dwTime)
{
std::cout < < "hello " < < std::endl;
}
void main()
{
int timer1 = 1;
HWND hwndTimer;
MSG msg;
SetTimer(NULL,timer1,5000,TimerProc);
int itemp;
while ( (itemp = GetMessage(&msg, NULL,NULL,NULL))&& (itemp!=0) && (-1 != itemp))
{
if (msg.message == WM_TIMER)
{
std::cout < < "i got the message " < < std::endl;
TranslateMessage(&msg);
DispatchMessage(&msg);
}
}
}
