解决方案
查看我为您制作的示例程序：
在Windows窗体中
放置一个按钮和Lable：
按钮名称为：Button1
Lable名称为：LBL1
定时器conral as Timer1
声明一个公共整数变量为ival
' ---- public variable
Dim ival As 整数 = 0
' ----按钮单击启动计时器
私有 Sub Button1_Click（发件人 A s 系统。对象，e As System.EventArgs）句柄 Button1.Click
LBL1.Visible = True
Timer1.Interval = 200
Timer1.Enabled = True
ival = 0
Timer1.Start（）
LBL1.Visible = True
结束 Sub
' ----计时器勾选事件使您的标签闪烁
私有 Sub Timer1_Tick（发件人 As System。 Object ，e As System.EventArgs） 句柄 Timer1.Tick
如果 LBL1.Visible = True 然后
LBL1.Visible = False
Else
LBL1.Visible = True
结束 如果
ival = ival + 1
如果 ival = 7 然后
如果 LBL1.Visible = False 然后
LBL1.Visible = True
结束 如果
Timer1 。停止（）
结束 如果
结束 Sub

尝试这个
< 正文 onload = changeColour（'flashtext'）; >
< script type = text / javascript >
函数changeColour（elementId）{
var interval = 1000;
var colour1 =＃ff0000;
var colour2 =＃000000;
if（document.getElementById）{
var element = document.getElementById（elementId）;
element.style.color =（element.style.color == colour1）？ colour2：colour1;
setTimeout（changeColour（'+ elementId +'），interval）;
}
}
< / script >
< p id = flashtext > 此文字将闪烁!!! < ; / p > < / body >

解决方案
Check this sample program i made for you :
In windows form
place one Button and Lable:
Button Name as :Button1
Lable Name as :LBL1
Timer conral as Timer1
Declare one public integer variable as ival
' ---- public variable Dim ival As Integer = 0 ' ---- Button Click Start the Timer Private Sub Button1_Click(sender As System.Object, e As System.EventArgs) Handles Button1.Click LBL1.Visible = True Timer1.Interval = 200 Timer1.Enabled = True ival = 0 Timer1.Start() LBL1.Visible = True End Sub ' ---- Timer Tick Event blink your label Private Sub Timer1_Tick(sender As System.Object, e As System.EventArgs) Handles Timer1.Tick If LBL1.Visible = True Then LBL1.Visible = False Else LBL1.Visible = True End If ival = ival + 1 If ival = 7 Then If LBL1.Visible = False Then LBL1.Visible = True End If Timer1.Stop() End If End Sub
