vb点虐 做闹钟步骤 vb添加时钟控件
用VB编写一个闹钟程序
做一个简单的闹钟程序很简单的。我这里不用if语句。首先我们在窗体上添加一个标签控件，再画一个“闹钟”，将闹钟得interval属性改为1000，双击闹钟，进入闹钟的代码视图，编写代码

private
sub
timer1_timer（）
label1.caption
=
time
end
sub就行了。谢谢采纳
跪求用vb点虐 做一个小闹钟！！
'加个定时器,textbox ,button,label Private Sub Timer1_Tick(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Timer1.Tick
Label1.Text = Now
If FF = Now And FF "2001-1-1" And Timer1.Tag = "" Then
Timer1.Tag = "1"
MsgBox("ff")
End If
End Sub Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
FF = TextBox1.Text
Timer1.Tag = ""
End Sub Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
FF = "2001-1-1"
End Sub'声音加个 AxMMControl控件 AxMMControl1.DeviceType = "waveaudio" ''''''''定义播放*.wav格式 AxMMControl1.FileName = "c:\1.wav" ''''''''载入文件， AxMMControl1.Command = "open" ''''''''打开载入的文件
AxMMControl1.From = 0 '从头开始
AxMMControl1.Command = "play"'保存时间,只要设定时把时间保存到文本文件就行,load 事件中读取,并对比是不是超时,.
利用vb点虐 实现小闹钟功能
Private Declare Function mciSendStringA Lib "winmm.dll" _
(ByVal lpstrCommand As String, ByVal lpstrReturnString As String, _
ByVal uReturnLength As Integer, ByVal hwndCallback As Integer) As Integer
Function PlayMidiFile(ByVal MusicFile As String) As Boolean
If System.IO.File.Exists(MusicFile) Then
mciSendStringA("stop music", "", 0, 0)
mciSendStringA("close music", "", 0, 0)
mciSendStringA("open " MusicFile " alias music", "", 0, 0)
PlayMidiFile = mciSendStringA("play music", "", 0, 0) = 0
End If
End Function
Private Sub Timer1_Tick(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Timer1.Tick
If TextBox1.Text = TimeOfDay Then
'具体提醒的东西，如你说的播放音乐
PlayMidiFile("自己添加路径")
End If
'时间格式要是这样的16:00:00
'timer的interval要设成1
'你还可以自己细化
End Sub
用vb做一个小闹钟
下面是一个时钟程序代码，你可以参考一下。
Const PI = 3.14159265
Dim H, W, R As Integer '窗体高、宽、圆半径
Private Sub BiaoKe()
Dim I As Integer
'外盘
Circle (W \ 2, H \ 2), R, vbBlue
'中心
Circle (W \ 2, H \ 2), 1, vbWhite
'盘面各点
For I = 0 To 59
If I Mod 5 = 0 Then
Circle (W \ 2 + R * Cos(I * PI / 30), H \ 2 + R * Sin(I * PI / 30)), 2, vbGreen
Else
Circle (W \ 2 + R * Cos(I * PI / 30), H \ 2 + R * Sin(I * PI / 30)), 1, vbWhite
End If
Next I
End Sub
Private Sub Form_Load()
Me.Show
Me.Cls
H = frmTime.ScaleHeight
W = frmTime.ScaleWidth
R = W \ 4
lbTime.Left = (frmTime.ScaleWidth - lbTime.Width) \ 2
lbTime.Top = frmTime.ScaleHeight - R \ 4
End Sub
Private Sub Form_Resize()
Call Form_Load
End Sub
Private Sub Timer1_Timer()
Dim T1, T2, T3 As Integer
Dim I, J, K As Integer
Me.Cls
T1 = Hour(Time): T2 = Minute(Time): T3 = Second(Time)
I = T1 - 15
J = T2 - 15
K = T3 - 15
'钟表外壳
Call BiaoKe
'画时针
Line (W \ 2, H \ 2)-(W \ 2 + 0.5 * (R * Cos((I + J / 60) * PI / 6)), H \ 2 + 0.5 * (R * Sin((I + J / 60) * PI / 6))), vbGreen
'画分针
Line (W \ 2, H \ 2)-(W \ 2 + 0.7 * (R * Cos((J + K / 60) * PI / 30)), H \ 2 + 0.7 * (R * Sin((J + K / 60) * PI / 30))), vbYellow
'画秒针
Line (W \ 2, H \ 2)-(W \ 2 + 0.9 * (R * Cos(K * PI / 30)), H \ 2 + 0.9 * (R * Sin(K * PI / 30))), vbRed
K = K + 1
If K 360 Then K = K Mod 360
lbTime.Caption = Time
End Sub
