在窗体上添加两个计时器,设置Timer1的属性:Interval=200,设置Timer2的属性:Enabled=False,interval=5000
- '如何实现文本动态显示
- Dim l As Integer, i As Integer, x As Integer, y As Integer
- Dim page As Integer
- Dim filenum As Integer
- Dim words As String
- Private Sub form_load()
- ChDrive App.Path
- ChDir App.Path
- FileName$ = "c:\text.txt"
- filenum = FreeFile
- Open FileName$ For Input As #filenum
- Do While Not EOF(filenum)
- Line Input #filenum, Text$
- words = words + Text$ + Chr(13) + Chr(10) '将文本内容赋值给words串变量,包括回车符和换行符
- Loop
- Close #filenum
- l = Len(words) '计算words串变量长度(字符个数)
- End Sub
- Private Sub Timer1_Timer()
- If page = 1 Then '满一页后清除窗体内容
- Form1.Cls
- page = 0
- Timer1.Interval = 200 '重置打字速度
- End If
- typewrite '调用打字子例程
- End Sub
- Public Sub typewrite()
- i = i + 1 '字符计数器
- x = x + 1
- CurrentX = 100 '设置打字的起始点
- CurrentY = 300
- CurrentX = CurrentX + x * 250 '设置字间距
- CurrentY = CurrentY + y * 280 '设置行间距
- t$ = Mid$(words, i, 1) '从words串中指定位置取一个汉字或标点符号
- Print t$ '在窗体上打印一个字符
- If x = 20 Or Mid$(words, i, 2) = Chr$(13) + Chr$(10) Then '设置行字符个数,若行字数满或段落结束(遇回车换行符)则换行
- y = y + 1
- x = 0
- End If
- If y = 12 Then '设置行数
- page = 1 '行数满为一页
- y = 0
- Timer1.Interval = 6000 '设置页显示停留时间
- End If
- If i > l Then '文本内容打印完毕,计时器2打开
- Timer1.Enabled = False
- Timer2.Enabled = True
- End If
- End Sub
- Private Sub Timer2_Timer()
- Timer2.Enabled = False
- Timer2.Enabled = False
- End '改变END,可执行其它子例程
- End Sub
