VB.net迷宫代码 迷宫程序代码

求vb.net的源代码，最好说明其解决问题，越多越好，满意加50分。

下面这段代码，是我用来计算每个月存500元进银行，连续30年，最后连本带利能有多少钱。这里面涉及复利计算。界面中右边的文本框用来输出每一次计算的结果。

Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click

  Dim nianxian As Integer '年限变量

  Dim dingcun As Integer '定存变量

  Dim fuli_big As Long '大复利

  Dim fuli_small As Long '小复利

  Dim i As Integer '循环变量

  Dim DATAstring As String '数据字符串

  nianxian = Val(年限_TextBox.Text)

  dingcun = Val(定存_TextBox.Text)

  DATAstring = ""

  For i = 1 To nianxian

      fuli_small = dingcun * (1 + 0.1875)

      dingcun = fuli_small

      fuli_big = fuli_big + fuli_small

      DATAstring = DATAstring + "[" + Trim(Str(i)) + "]" + Str(fuli_big) + Chr(13) + Chr(10)

      'DATAstring = DATAstring + "[" + Trim(Str(i)) + "]" + Str(fuli_small) + Chr(13) + Chr(10)

  Next

  'fuli_big = fuli_small

  TextBox1.Text = DATAstring

  结果_TextBox.Text = Str(fuli_big) + "元"

跪求vb.net代码

新建窗口，添加picture控件

利用line()方法画线

line(开始x坐标,开始y坐标)-(结束x坐标,结束y坐标),线的颜色，画线的方式(默认为线，B为矩形无填充，BF为填充的矩形)

For i = 1 To 16

Picture1.Line (0, Picture1.Height / 2)-(i * (Picture1.Width / 16), 0), RGB(255, 0, 0)

Picture1.Line (0, Picture1.Height / 2)-(i * (Picture1.Width / 16), Picture1.Height), RGB(255, 0, 0)

Picture1.Line (Picture1.Width, Picture1.Height / 2)-(i * (Picture1.Width / 16), 0), RGB(0, 255, 0)

Picture1.Line (Picture1.Width, Picture1.Height / 2)-(i * (Picture1.Width / 16), Picture1.Height), RGB(0, 255, 0)

Next i

如果要在窗口上画也可以调用窗口的line方法即form.line()

求VB.net程序源代码 绘图板、二十一点游戏、计算器、井字棋游戏、屏幕保护程序等

说明：1.共有4个文本框其，其中三个是填入或输出数据的（名称分别是：txta txtb txtc），剩下的那个是符号(txtd)2.共7个按钮，4个是符号按钮，一个计算，一个清零．这是我弄的程序”袖珍计算器”代码也是自己编写的，代码如下：通用声明Dim j As Integer '定义j为整型

Private Sub Text1_Change()End SubPrivate Sub Command1_Click()

txtfuhao.Text = "+" '将”＋”显示到文本框txtfuhao.Text中

End SubPrivate Sub Command2_Click()

txtfuhao.Text = "-" ''将”-”显示到文本框txtfuhao.Text中

End SubPrivate Sub Command3_Click()

txtfuhao.Text = "×" '将”×”显示到文本框txtfuhao.Text中

End SubPrivate Sub Command4_Click()

txtfuhao.Text = "÷" 将”÷”'显示到文本框txtfuhao.Text中

End Sub

Private Sub Command5_Click()

Dim a, b, c As Integer

a = Val(txta.Text) '将txta.Text里的内容转化为数值型,然后再赋给a

b = Val(txtb.Text) '将txtb.Text里的内容转化为数值型,然后再赋给b

If txtfuhao.Text = "+" Then '运算过程

c = a + b '运算过程

ElseIf txtfuhao.Text = "-" Then '运算过程

c = a - b '运算过程

ElseIf txtfuhao.Text = "÷" Then '运算过程

c = a / b '运算过程

ElseIf txtfuhao.Text = "×" Then '运算过程

c = a * b '运算过程

Else

j = MsgBox("您输入的符号不正确", vbOKOnly, "错误信息")

End If

txtc.Text = c '将运算结果c输出到文本框txtc中

End SubPrivate Sub Command6_Click()

txta.Text = "" '将空字符输入到文本框内（刷新）

txtb.Text = "" '将空字符输入到文本框内（刷新）

txtc.Text = "" '将空字符输入到文本框内（刷新）

txtfuhao.Text = "" '将空字符输入到文本框内（刷新）

关于VB中A*寻路算法的提问

定理：穿越于一组互不相交的多边形障碍物S之间、从Pstart通往Pgoal的任何一条最短路径，都是一条多边形路径，其中所有的内部顶点都是S的顶点。

推广：所有最短路径问题。

结论：只有普遍适用的算法，没有普遍适用的代码。

补充：只有问题实例化才能写出适用代码。

你所遇到的可不只是寻路问题，二维寻路相对简单点，我猜测你的问题产生在“碰撞”上，建议你多学习一下“计算几何学”、“计算机图形学”、“机器人运动学”等，当然，编程的基本功也很重要。其实，带有运动的游戏编程是很复杂的。你也可以将你的程序包发给我等我有时间帮你看看。

谁能帮我用VB.net做个简单的游戏设计啊,我快愁死了

这是个vb6的BINGO小游戏的代码 如果要源程序 去我资料里找我网盘的地址 下载bingo.rar

因为没有任何第三方控件，可以直接转成vb.net的！~
