实验报告

系别：电子信息科学与技术班级：电子2班姓名：张猛日期：3月18号

一：试验目的

1.图片设计

2.随机图形

二：实验内容

1先界面设置和属性设置

2编写代码

图片设计

public TopBottom, LeftRight As String

Private Sub Form_Click()

If Timer1.Enabled = False Then

Timer1.Enabled = True

Else

Timer1.Enabled = False

End If

End Sub

Private Sub Form_KeyPress(KeyAscii As Integer)

Select Case KeyAscii

Case 61

Timer1.Interval = 10

Case 45

Timer1.Interval = 100

End Select

End Sub

Private Sub Form_Load()

TopBottom = "0"

LeftRight = "0"

End Sub

Private Sub Timer1_Timer()

Select Case TopBottom & LeftRight

Case "00"

Form1.Image1.Top = Form1.Image1.Top - 10

Form1.Image1.Left = Form1.Image1.Left - 10

Form1.Image1.Move _

Form1.Image1.Left - 10, Form1.Image1.Top - 10

If Form1.Image1.Top <= 0 Then

TopBottom = "1"

End If

If Form1.Image1.Left <= 0 Then

LeftRight = "1"

End If

Case "10"

Form1.Image1.Top = Form1.Image1.Top + 10

Form1.Image1.Left = Form1.Image1.Left - 10

If Form1.Image1.Top >= _

Form1.ScaleHeight - Form1.Image1.Height Then

TopBottom = "0"

End If

If Form1.Image1.Left <= 0 Then

LeftRight = "1"

End If

Case "01"

Form1.Image1.Top = Form1.Image1.Top - 10

Form1.Image1.Left = Form1.Image1.Left + 10

If Form1.Image1.Top <= 0 Then

TopBottom = "1"

End If

If Form1.Image1.Left >= _

Form1.ScaleWidth - Form1.Image1.Width Then

TopBottom = "0"

End If

Case "11"

Form1.Image1.Top = Form1.Image1.Top + 10

Form1.Image1.Left = Form1.Image1.Left + 10

If Form1.Image1.Top >= _

Form1.ScaleHeight - Form1.Image1.Height Then

TopBottom = "0"

End If

If Form1.Image1.Left >= _

Form1.ScaleWidth - Form1.Image1.Width Then

LeftRight = "0"

End If

End Select

End Sub

2随机图形代码

Private Sub Command1_Click()

Timer1.Enabled = True

Timer1.Interval = 100

End Sub

Private Sub Command2_Click()

Form1.Cls

End Sub

Private Sub Command3_Click()

Timer1 = False

End Sub

Private Sub Form_MouseDown(Button As Integer, Shift As Integer, X As Single, Y As Single)

'Form1.Circle (Int(Rnd * 8000), Int(Rnd * 8000)), Int(Rnd * 800)

'FillStyle = Int(Rnd * 7)

'FillColor = QBColor(Int(Rnd * 15))

'Timer1.Interval = 10

End Sub

Private Sub Timer1_Timer()

Form1.Circle (Int(Rnd * 8000), Int(Rnd * 8000)), Int(Rnd * 800)

FillStyle = Int(Rnd * 7)

FillColor = QBColor(Int(Rnd * 15))

Line (Int(Rnd * 8000), Int(Rnd * 8000))-(Int(Rnd * 8000) + 1000, Int(Rnd * 8000))

End Sub

三：心得体会

1随机图形要用到Rnd（x）的函数

2在设计图形时应该灵活运用各种函数，发挥想象，使自己的程序活起来。

3shape是图形函数

4Topbottom,Leftright函数分别表示上下左右，区分运动方向。

四：解决问题

在编完代码后无法执行程序，逐项检测各个阶段编码，找到问题的所在。以后还得多多练习。

五：没有解决的问题

不知道函数的正确使用方法，只知道安课本的步骤作，以后要灵活应用，举一反三，多多看课本或者视频来学习vb编程。
