vb 设计新建一个工程，完成“秒表计时”程序的设计，如图13-11所示。具体要求如下：_CMS教程

一秒的速度太慢，我给你设置了001秒

这什么东西啊，也太乱了吧！用一个GetTickCount这个API函数；

GetTickCount函数

函数功能：GetTickCount返回（retrieve）从 *** 作系统启动到现在所经过（elapsed）的毫秒数，它的返回值是DWORD。

函数原型： DWORD GetTickCount(void);

C/C++头文件：winbaseh

windows程序设计中可以使用头文件windowsh

程序示例

//代替time函数来初始化随机数生成器

#include<stdioh>

#include<windowsh>

int main()

　{

int i,k,r;

for(i=0;i<10;i++)

{

srand(GetTickCount());

printf("\n");

for(k=0;k<5;k++)

{

r=rand();

printf("%d ",r);

}

return 0;

}

注意事项

GetTickcount函数：它返回从 *** 作系统启动到当前所经过的毫秒数，常常用来判断某个方法执行的时间，其函数原型是DWORD GetTickCount(void)，返回值以32位的双字类型DWORD存储，因此可以存储的最大值是2-1 ms约为4971天，因此若系统运行时间超过4971天时，这个数就会归0，MSDN中也明确的提到了:"Retrieves the number of milliseconds that have elapsed since the system was started, up to 497 days"。因此，如果是编写服务器端程序，此处一定要万分注意，避免引起意外的状况。
