用vb编了个数独计算器

平时很喜欢玩数独游戏，每天只要信报上有数独游戏，那就不看别的了，专心致志玩一路。

昨天突然想自己编一个软件来算吧，于是就有了这篇文章和一个vb的数独计算器。

谈思想吧，思想最重要：我用了最最笨的方法，就是每个空位都从1～9挨个填，出了问题再折回来重新填。

 

所以这样的想法一定要用到递归了，就是不断调用自身来达到目的。

 

东西简单，所以代码也简单：

我用了81个text来填数：text1（0）～text1(80),存到一个 Mtx(81)的数组中。

而且先写了一个填写检查程序：（目的是检查是否可以在x,y这个位置填入此Num。）

Function Tcheck(arrayc() As Integer, x As Integer, y As Integer,num As Integer)
For i = 0 To 8
    If Mtx(i, y) = num Then
        Tcheck = False
        Exit Function
    End If
    If Mtx(x, i) = num Then
        Tcheck = False
        Exit Function
    End If
Next i

            For i = 0 To 2
                For j = 0 To 2
                        If (arrayc((x/3)*3 + i, (y/3)*3 + j) = num) Then
                            Tcheck = False
                            Exit Function
                        End If
                Next j
            Next i
Tcheck = True

End Function

 

Private Function checkexistNum()
'检查现有的数据是否存在问题
Dim i As Integer
Dim j As Integer
Dim temp As Integer

For i = 0 To 8
    For j = 0 To 8
        If (Mtx(i, j) <> 0) Then
            temp = Mtx(i, j)
            Mtx(i, j) = 0
            If Tcheck(Mtx, i, j, temp) = False Then
                checkexistNum = False
                errorstr = temp
                Text1(i * 9 + j).SetFocus
                Exit Function
            End If
            Mtx(i, j) = temp
        End If
    Next j
Next i
checkexistNum = True
End Function

 

下面这个程序就是最重要的递归函数了：

Function CalcArray(arrayn() As Integer)
Dim k As Integer
Dim i As Integer
Dim j As Integer

 For i = 0 To 8
    For j = 0 To 8
        If arrayn(i * 9 + j) = 0 Then '原来的值为０才能进行赋值试验
            Dim flag As Boolean
            flag = False
           
            For k = 1 To 9 '准备填数
                flag = Tcheck(arrayn(), i, j, k)
                If flag = True Then
                    arrayn(i * 9 + j) = k
                    If CalcArray(arrayn) = False Then
                        arrayn(i * 9 + j) = 0
                        flag = False
                    Else
                        CalcArray= True
                        Exit Function
                    End If
                End If
            Next k
           
            If flag = False Then
                CalcArray = False
                Exit Function
            End If
           
        End If
    Next j
 Next i
 CalcArray = True
 End Function

 

ok，最后一步就是主函数了：

Private Sub CalculatorCT_Click()

Dim i, j As Integer

SodoError = 0
t = Timer
transfer '这个就是将text1转到Mtx()中去
If SodoError = 1 Then
    Exit Sub
End If

If checkexistNum = False Then
 MsgBox "现有数据存在问题:" & errorstr
 Exit Sub
End If

If CalcArray(Mtx) = False Then
    MsgBox "无法解出", , "龙卷风数独"
Else
        '将资料填回Text1中
        For i = 0 To 8
           For j = 0 To 8
                Text1(j + (i * 9)) = Mtx(i, j)
           Next j
        Next i
        MsgBox "计算完成", , "龙卷风数独"
End If

End Sub

呵呵，简单吧！
