Win32控制台程序的定时器实现(转载)
在控制台中使用定时器不能简单的SetTimer了事,这在控制台里这种SetTimer的方式是有点麻烦的,需要自己写消息循环投递WM_TIMER消息。其实在控制台里可以使用多媒体时钟来计时:
example:
//启动计时器
MMRESULT nIDTimerEvent = timeSetEvent(
1000,//延时1秒
0,
TimeProc,
0,
(UINT)TIME_PERIODIC);
if( nIDTimerEvent == 0 )
cout<<"启动计时器失败"<<endl;
//回调过程(时钟到来,回调函数被系统自动调用)
void CALLBACK TimeProc(
UINT uID,
UINT uMsg,
DWORD dwUser,
DWORD dw1,
DWORD dw2
)
{
cout<<"时钟到来"<<endl;
}
当然了,你要是习惯于SetTimer,那就用SetTimer吧:
下面是我在Console下用SetTimer写的一个例子:
#include <windows.h>
#include <iostream>
using namespace std;
void CALLBACK TimeProc(
HWND hwnd,
UINT message,
UINT idTimer,
DWORD dwTime);
int main()
{
SetTimer(NULL,1,1000,TimeProc);
MSG msg;
while(GetMessage(&msg,NULL,0,0))
{
if(msg.message==WM_TIMER)
{
DispatchMessage(&msg);
}
}
return 0;
}
void CALLBACK TimeProc(
HWND hwnd,
UINT message,
UINT idTimer,
DWORD dwTime)
{
cout<<"a timer comming"<<endl;
}
example:
//启动计时器
MMRESULT nIDTimerEvent = timeSetEvent(
1000,//延时1秒
0,
TimeProc,
0,
(UINT)TIME_PERIODIC);
if( nIDTimerEvent == 0 )
cout<<"启动计时器失败"<<endl;
//回调过程(时钟到来,回调函数被系统自动调用)
void CALLBACK TimeProc(
UINT uID,
UINT uMsg,
DWORD dwUser,
DWORD dw1,
DWORD dw2
)
{
cout<<"时钟到来"<<endl;
