VB版

VB声明:

Declare Function GetTickCount Lib "kernel32" Alias "GetTickCount" () As Long

例如：实现延时

Public Sub Sleep(numa As Long)

Dim num1 As Long

Dim num2 As Long

Dim numb As Long

numb = 0

num1 = GetTickCount

Do While numa - numb > 0

num2 = GetTickCount

numb = num2 - num1

DoEvents

Loop

End Sub

C++版

CString s;

DWORD k=::GetTickCount(); //获取毫秒级数目

int hm=k/3600000; //hm为小时数

int ms=(k-3600000*hm)/60000; //ms为分钟数

int se=(k-3600000*hm-60000*ms)/1000; //se为秒数（除以1000是因为k精确到毫秒）

s.Format("%d:%d:%d",hm,ms,se); //输出时、分、秒
