南京理工大学能源与动力工程学院
知识点：（1）控件数组；（2）绘图；（3）菜单；（4）文本文件的读写；（5）多
模块设计；（6）资源文件的使用。

一、功能简介：
（1）启动程序后，进入初始界面(form1)，游戏共有3种预定义的难度级别，为初级（9行9列10个雷），中级（16行16列40个雷），高级（16
行30列99个雷），还有“自定义”命令，可以自行定义雷区行数，
列数和雷数；
（2）雷区上面的小脸可以变化，显示微笑，惊讶，痛苦，胜利。

在任何情况下单击小脸可以重新开始游戏；
（3）鼠标左击排雷，右击插小旗，打问号；
（4）方格里面的数字表示方格周围的雷数；
（5）扫雷成功时候，调用文件看有没有打破该级别的记录。

二、课程设计的详细设计
（1）.绘制方格，使用如下程序：
Dim picf As New StdPicture 'picf保存图片对象
form1.pic2.ScaleMode = 3 '以像素为单位
form1.pic2.Cls '图片框清空
Set picf = LoadPicture(App.Path & "1.bmp")
For i = 0 To m - 1
For j = 0 To n - 1
form1.pic2.PaintPicture picf, j * 16, i * 16 '加载图片
Next
Next
（2）.放雷的方法：定义一个二维数组aarMine,行数为inthang，列数为intlie，雷的个数intlei，使用下面的程序来解决：
Randomize
ReDim arrMine(inthang, intlie)
Do While int3 < intlei '雷数的随机分布
col = Int(Rnd * intlie)
ln = Int(Rnd * inthang)
If arrMine(ln, col) = False Then
arrMine(ln, col) = True
int3 = int3 + 1
End If
Loop
（3）.使用三个pictureclip控件来管理图片：
form1.PictureClip1.Picture = LoadPicture(App.Path & "face.bmp")
form1.PictureClip1.Rows = 1
form1.PictureClip1.Cols = 5
form1.PictureClip2.Picture = LoadPicture(App.Path & "number.bmp")
form1.PictureClip2.Rows = 1
form1.PictureClip2.Cols = 12
form1.PictureClip3.Picture = LoadPicture(App.Path & "mine.bmp")
form1.PictureClip3.Rows = 1
form1.PictureClip3.Cols = 15
（4）.使用递归过程（fangkai）来开启方格：
Private Sub fankai(ByVal int1 As Integer, ByVal int2 As Integer) Dim hang As Integer
Dim lie As Integer
Top:
If int1 - 1 = 0 Then GoTo Below
If Sign(int1 - 1, int2) = False Then
Sign(int1 - 1, int2) = True
hang = int1 - 1
lie = int2
GoTo Ddd
End If
Below:
If int1 = inthang Then GoTo Left
If Sign(int1 + 1, int2) = False Then
Sign(int1 + 1, int2) = True
hang = int1 + 1
lie = int2
GoTo Ddd
End If
Left:
If int2 - 1 = 0 Then GoTo Right
If Sign(int1, int2 - 1) = False Then
Sign(int1, int2 - 1) = True
lie = int2 - 1
hang = int1
GoTo Ddd
End If
Right:
If int2 = intlie Then GoTo Righttop
If Sign(int1, int2 + 1) = False Then
Sign(int1, int2 + 1) = True
lie = int2 + 1
hang = int1
GoTo Ddd
End If
Righttop:
If int2 = intlie Or int1 - 1 = 0 Then GoTo Lefttop
If Sign(int1 - 1, int2 + 1) = False Then
Sign(int1 - 1, int2 + 1) = True
lie = int2 + 1
hang = int1 - 1
GoTo Ddd
End If
Lefttop:
If int2 = 1 Or int1 - 1 = 0 Then GoTo Leftbelow
If Sign(int1 - 1, int2 - 1) = False Then
Sign(int1 - 1, int2 - 1) = True
lie = int2 - 1
hang = int1 - 1
GoTo Ddd
End If
Leftbelow:
If int2 = 1 Or int1 = inthang Then GoTo Rightbelow
If Sign(int1 + 1, int2 - 1) = False Then
Sign(int1 + 1, int2 - 1) = True
lie = int2 - 1
hang = int1 + 1
GoTo Ddd
End If
Rightbelow:
If int2 = intlie Or int1 = inthang Then Exit Sub
If Sign(int1 + 1, int2 + 1) = False Then
Sign(int1 + 1, int2 + 1) = True
lie = int2 + 1
hang = int1 + 1
GoTo Ddd
Else
Exit Sub
End If
Ddd:
If leishu(hang, lie) <> 0 Then
pic2.PaintPicture PictureClip3.GraphicCell(15 - leishu(hang, lie)), (lie - 1) * 16, (hang - 1) * 16
GoTo Top
Else
pic2.PaintPicture PictureClip3.GraphicCell(15), (lie - 1) * 16, (hang - 1) * 16
Call fankai(hang, lie)
GoTo Top
End If
（5）.“扫雷英雄榜”分3个文件夹保存（chuji,zhongji,gaoji ）
If inthang = 9 And intlie = 9 Then
Open App.Path & "\chuji.txt" For Input As 1
Line Input #1, str1(0)
str2(0) = CInt(Left(str1(0), InStr(str1(0), " ")))
If intNum < CInt(str2(0)) Then
InputBox " 恭喜你破了本难度的记录！请留下大名", , "无名侠"
End If
Close 1
ElseIf intlie = 16 And inthang = 9 Then
Open App.Path & "\zhongji.txt" For Input As 1
Line Input #1, str1(1)
str2(1) = CInt(Left(str1(1), InStr(str1(1), " ")))
If intNum < CInt(str2(1)) Then
InputBox " 恭喜你破了本难度的记录！请留下大名", , "无名侠"
End If
Close 1
ElseIf intlie = 30 And inthang = 16 Then
Open App.Path & "\gaoji.txt" For Input As 1
Line Input #1, str1(2)
str2(2) = CInt(Left(str1(2), InStr(str1(2), " ")))
If intNum < CInt(str2(2)) Then
InputBox " 恭喜你破了本难度的记录！请留下大名", , "无名侠"
End If
Close 1
End If
（7）.通过数组a（）来确定插小旗，同时右上角的雷数随之改变：先在Module1中定义数组Sign()和a()：
ReDim Sign(1 To inthang, 1 To intlie)
ReDim a(0 To inthang - 1, 0 To intlie - 1)
然后在form1写如以下程序：
If Sign(int1 + 1, int2 + 1) = False Then
a(int1, int2) = a(int1, int2) + 1
If a(int1, int2) Mod 3 = 1 Then
pic2.PaintPicture PictureClip3.GraphicCell(1), int2 * 16, int1 * 16
k = k - 1
End If
If a(int1, int2) Mod 3 = 2 Then
pic2.PaintPicture PictureClip3.GraphicCell(2), int2 * 16, int1 * 16
k = k + 1
End If
If a(int1, int2) Mod 3 = 0 Then
pic2.PaintPicture PictureClip3.GraphicCell(0), int2 * 16, int1
* 16
End If
If k >= 0 Then
imglei(0).Picture = form1.PictureClip2.GraphicCell(11 - k \ 100)
imglei(1).Picture = form1.PictureClip2.GraphicCell(11 - k \
10 Mod 10)
imglei(2).Picture = form1.PictureClip2.GraphicCell(11 - k Mod 10)
Else
imglei(0).Picture = form1.PictureClip2.GraphicCell(0)
imglei(1).Picture = form1.PictureClip2.GraphicCell(11 + k \
10 Mod 10)
imglei(2).Picture = form1.PictureClip2.GraphicCell(11 + k Mod 10)
End If
End If
三、调试程序的过程
（1）在写程序时，刚开始自己没有想到要用标准模块来定义全局变量和过程，这样虽然也能实现功能，但增加了调试程序的
难度，最后，自己试着运用标准模块来定义，果然收到不同
的效果；
（2）在显示LED风格的数字时，自己想过要用LoadResPicture 函数加载图片并使用PaintPicture方法绘制，而且书上也介
绍了相应代码，但自己还是感觉使用PictureClip控件更方
便，更容易理解，于是自己便选择了运用后者；
（3）在记录游戏成绩时文件打不开，提示信息说是类型不匹配和路径错误，自己调试了好久，现把前后的代码记录如下：
错误的代码：
If inthang = 9 and intlie=9 Then
Open "F:\chuji.txt" For Input As 1
Line Input #1, str1(0)
str2(0) = Left(str1(0), " ")
If intNum < CInt(str2(0)) Then
InputBox " 恭喜你破了本难度的记录！请留下大名", , "无名侠"
End If
Close 1
ElseIf intlie = 16 and inthang=16Then
Open "F:\zhongji.txt" For Input As 1
Line Input #1, str1(1)
str2(1) = Left(str1(1), " ")
If intNum < CInt(str2(1)) Then
InputBox " 恭喜你破了本难度的记录！请留下大名", , "无名侠"
End If
Close 1
ElseIf intlie = 30 and inthang =16 Then
Open "F:\gaojiji.txt" For Input As 1
Line Input #1, str1(2)
str2(2) = Left(str1(2), " ")
If intNum < CInt(str2(2)) Then
InputBox " 恭喜你破了本难度的记录！请留下大名", , "无名侠"
End If
Close 1
End If
End If
改过的代码：如上述课程设计的详细设计中的（5）的代码。

四、课程设计心得
通过该程序,让我充分体会到了理论与实践相结合的重要性.VB课程设计，它不比期末考试与二级考试，它更看重的是应用技巧。

而其，其中有好多的算法和技巧要求了解和掌握，不去问同学或老师，仅凭一己之力，是很难预期完成的。

在编程时的收获不少，除了对编程语言有了更深一步的了解，还有同学之间的友谊加深。

在自己有了困难时，同学或老师的大力帮助，自己真的很感动。

再一次谢谢我的同学和老师。

当然在编程时还有许多经验和教训值得反思，现在自己整理一下：
（1）在开始编程之前，要先构思各种功能实现的算法，想好了以后在上机编写，不要急于上机；
（2）编程时一定要注意变量的使用，切勿胡乱使用变量。

我在编程时候最大
的问题就是变量总是搞错，那就要反复调试，最后才搞清楚变量的含义；（3）编程不要过于复杂，多调用过程；
（4）编程过程中，由于自己对理论知识的欠缺，很多方面都很模糊。

自己不得不花大量时间去查阅资料并且整理出来，这充分证明了自己对VB的了解甚少，需要在以后的学习中来完善。

（5）编程结束，自己再多运行，调试几次可能有某个方面自己没注意到，当中得到了很多同学的帮助，我再一次谢谢他们。
