2. 如何记录闹时间？

使用数组来存储闹时信息。

Dim NaoShi(0 To 3) As String '存储闹时时间

3. 如何设置闹时时间？

在文本框Text1.Text中输入所需要的时间，通过如下方法，将闹时时间基茄磨添加到List1中显示

List1.AddItem Text1.Text

4. 如何实现闹时判断？纳携

For I = 0 To 3

k = NaoShi(I)

If k = Label1.Caption Then

PlaySound1.URL = App.Path &RingFile

End If

Next

5. 如何设置和显示12小制？

Label1.Caption = Format(Time, "hh:mm:ss AM/PM")

6. 如何整点报时？

s = Second(Time)

m = Minute(Time)

h = Hour(Time)

If m = 0 And s = 0 Then

PlaySound1.URL = App.Path &"\bibi.wav"

End If

7. 如何绘制电子钟时分刻度？

Dim X, Y, rn As Single

Dim x0, y0 As Single

Dim I As Integer

x0 = Shape2(1).Left + Shape2(1).Width / 2

y0 = Shape2(1).Top + Shape2(1).Height / 2

rn = len_S + 100

FillStyle = 0

For I = 1 To 60

X = x0 + rn * Sin(pi * I / 30)

Y = y0 + rn * Cos(pi * I / 30)

If (I Mod 5 = 0) Then

FillColor = vbRed

Circle (X, Y), 100, vbRed '时的刻度

Else

FillColor = vbBlue

Circle (X, Y), 50, vbBlue '分的刻度

End If

Next I

8. 时、分、秒针的长度的计算。

len_S = Sqr((LineS.Y2 - LineS.Y1) ^ 2 + (LineS.X2 - LineS.X1) ^ 2) '秒针长度

len_M = Sqr((LineM.Y2 - LineM.Y1) ^ 2 + (LineM.X2 - LineM.X1) ^ 2) '分针长度

len_H = Sqr((LineH.Y2 - LineH.Y1) ^ 2 + (LineH.X2 - LineH.X1) ^ 2) '时针长度

9. 如何播放单个语音？

10. 如何连续播放语音？

1）时间的分解与语音播放文件的生成

' 语音报时模块

Dim s, m, h, I, n As Byte

Dim TimeNum(6) As Integer

'时间的获得

s = Second(Time)

m = Minute(Time)

h = Hour(Time)

'时间的分搏斗解

TimeNum(0) = Int(h / 10)

TimeNum(1) = h Mod 10

TimeNum(2) = Int(m / 10)

TimeNum(3) = m Mod 10

TimeNum(4) = Int(s / 10)

TimeNum(5) = s Mod 10

'语音文件名

I = 0

n = 0

If TimeNum(n) = 0 Then

n = n + 1

Sound(I) = "T" &Format(TimeNum(n), "00") &".wav"

Else

Sound(I) = "T" &Format(TimeNum(n), "00") &".wav"

I = I + 1

Sound(I) = "Shi.wav"

n = n + 1

If TimeNum(n) Then

I = I + 1

Sound(I) = "T" &Format(TimeNum(n), "00") &".wav"

End If

End If

'这时只给出时的分解与播放文件名处理。

2）通过定时器2进行定时，每隔一定时间，播放一个文件。Playlist数组中事先保存有时分秒所对应的语句文件名。

Private Sub Timer2_Timer()

PlaySound1.URL = Sound(Playlist)

If Playlist = PlayCont Then

Timer2.Interval = 0

Else

Playlist = Playlist + 1

End If

End Sub

11. 光标定位与校时修改实现

Option Explicit

Dim Temp As Variant

Dim SetStatus As Integer

Dim CurMinute, CurHour, CurSecond As Integer

Dim CurTime As Variant

Const EM_GETSEL = &HB0

Const EM_LINEFROMCHAR = &HC9

Const EM_LINEINDEX = &HBB

Dim LineNo As Long, ColNo As Long

Private Declare Function SendMessage Lib "user32" Alias "SendMessageA" (ByVal hwnd As Long, ByVal wMsg As Long, ByVal wParam As Long, lParam As Any) As Long

Public Sub GetCaretPos(ByVal TextHwnd As Long, LineNo As Long, ColNo As Long)

Dim I As Long, J As Long

Dim lParam As Long, wParam As Long

Dim k As Long

'首先向文本框传递EM_GETSEL消息以获取从起始位置到

'光标所在位置的字符数

I = SendMessage(TextHwnd, EM_GETSEL, wParam, lParam)

J = I / 2 ^ 16

'再向文本框传递EM_LINEFROMCHAR消息根据获得的字符

'数确定光标以获取所在行数

LineNo = SendMessage(TextHwnd, EM_LINEFROMCHAR, J, 0)

LineNo = LineNo + 1

'向文本框传递EM_LINEINDEX消息以获取所在列数

k = SendMessage(TextHwnd, EM_LINEINDEX, -1, 0)

ColNo = J - k + 1

End Sub

Private Sub Command1_Click()

Unload Me
