定时器
除了用settime 以外
还可以怎么实现定时器
我现在是要求在一个星期内七天每天不同的时间做不同的事情
用settime可以实现
但是自我感觉效果不好
还有没有别的方法

也可以用线程实现定时器，这现还可以避免UI挂起....
#define TIMER_SLEEP 10000
DWORD WINAPI TimerThread(LPARAM pamaram)
{
UINT oldTickCount, newTickCount;
oldTickCount = GetTickCount();
while(TRUE)
{
while(TRUE)
{
newTickCount = GetTickCount();
if(newTickCount - oldTickCount >= TIMER_SLEEP)
{
oldTickCount = newTickCount;
break;
}
else
SwitchToThread();
}
// Call your function
}
return 0;
}
HANDLE hThread = CreateThread....phisherr 2010-08-07
定时器里面调用GetSystemTime，然后在根据时间决定该干什么

我现在用的就是GetSystemTime
不过大家的意见我会先试验一下
有结果了我给大家分

可以用CreateWaitableTimer创建一个等待定时器内核对象来达到定时的效果
MSDN有个例子：
Using Waitable Timer Objects
The following example creates a timer that will be signaled after a 10 second delay. First, the code uses the CreateWaitableTimer function to create a waitable timer object. Then it uses the SetWaitableTimer function to set the timer. The code uses the WaitForSingleObject function to determine when the timer has been signaled.
#define _WIN32_WINNT 0x0500
#include <windows.h>
#include <stdio.h>
int main()
{
HANDLE hTimer = NULL;
LARGE_INTEGER liDueTime;
liDueTime.QuadPart=-100000000;
// Create a waitable timer.
hTimer = CreateWaitableTimer(NULL, TRUE, "WaitableTimer");
if (!hTimer)
{
printf("CreateWaitableTimer failed (%d)\n", GetLastError());
return 1;
}
printf("Waiting for 10 seconds...\n");
// Set a timer to wait for 10 seconds.
if (!SetWaitableTimer(hTimer, &liDueTime, 0, NULL, NULL, 0))
{
printf("SetWaitableTimer failed (%d)\n", GetLastError());
return 2;
}
// Wait for the timer.
if (WaitForSingleObject(hTimer, INFINITE) != WAIT_OBJECT_0)
printf("WaitForSingleObject failed (%d)\n", GetLastError());
else printf("Timer was signaled.\n");
return 0;
}

方法多了去了, 动动脑子, 用GetSystemTime总可以吧.

如果是隔了天的话，应该是要考虑关机的情况的，而不是考虑定时器的问题。
是不是应该让程序自启动，然后监视计算机时间然后根据时间来判断该做什么！
GetSystemTime不错！

用SetTimer或其它的定时器, 你一周七天不关机? 断电怎么办? Windows DOWN怎么半?
想想Windows Schedule怎么做...
