winmmԴ??
1）
启动visual basic6.0 ，打开一个新的PAQ算法源码标准工程。
2）
在窗体上Form1上添加6个标签空间（Label） 2个命令按钮（CommandButton）和1个计时器（Timer）。飞飞影音系统源码命令按钮的量价决策公式源码Caption属性分别为“启动”“停止”
Timer1的Interval属性为
Label1 Label2 Label3的Caption属性分别为“开始时间”“结束时间”“经过时间” Timer1的Enable属性为False
3）代码
Dim Starttime As Variant
Dim End time As Variant
Dim Elapsed As Variant
Private Sub cmdStart_Click()
'显示开始时间
lblStart.Caption=Time$
Starttime=Now
'启动时钟控件
Timer1.Enabled=Ture
End Sub
Private Sub cmdStop_Click()
'记录停止时间
Endtime=Now
'关闭时钟控件
Timer1.Enabled=False
'显示经过时间
lblApaed.Caption=Format(Endtime-Starttime,"hh:mm:ss"
End Sub
Private Sub Timer1_Timer()
lblStop.Caption=Time$
End Sub
以上是用VB6.0实现的
