vb.net数独源码 用vb编写数独游戏代码

IT技术源码

vb写的数独查找答案的源代码 ， 最好是vb6已发送 ， 
以下是递归的主要函数
Function TianChong1_1DA(x As Long, y As Long) As Boolean
Dim tmp As Long, JiXu As Boolean
For m = 1 To 9
If fDA(x, y, m) = 0 Then
If fDA(x, y, 0) = 0 Then fDA(x, y, 0) = m
TCJishuDA = TCJishuDA + 1
ReDim Preserve QingKong(TCJishuDA)
tmp = TianChongDA
If tmp1 And tmp2 Then
TianChong1_1DA tmp Mod 10, Int(tmp / 10)
End If
If jieJS0 Then TianChong1_1DA = True
If yuanSSJ(x, y) = 1 Then Exit Function
For n = 1 To 9
For nn1 = 1 To 9
For nn = 1 To 9
fDA(n, nn, nn1) = 0
Next
Next
Next
If fDA(x, y, 0) = m Then fDA(x, y, 0) = 0
QingKong_1DA (TCJishuDA)
TCJishuDA = TCJishuDA - 1
ReDim Preserve QingKong(TCJishuDA)
TCBiaojiDA
End If
Next
End Function

vb.net中如何利用api函数获取网页源代码？？？Dim MyClient As WebClient = New WebClient
Dim MyReader As New System.IO.StreamReader(MyClient.OpenRead(url), System.Text.Encoding.Default) '定义新vb.net数独源码的文件流并读取网页文件数据vb.net数独源码 ， url表示需要打开的网页地址
Dim longTxt As String = MyReader.ReadToEnd 'longtxt存储了网页的源码
MyReader.Close()
利用VB.NET实现导出DataTable数据到excel中，各位大侠帮帮忙，最好有源码，谢谢 ， 江湖救急刚好写了个Helper类vb.net数独源码，vb.net数独源码你试验一下DataTable2Exce(这个方法代码如下vb.net数独源码：
Imports System.IO
Imports System.Data
Imports System.Data.OleDb
Public MustInherit Class ExcelHelper
Private Shared Function buildConnStr(excelFilePath As String) As String
Dim excelFileInfo As New System.IO.FileInfo(excelFilePath)
Dim constr As String
If excelFileInfo.Extension = ".xlsx" Then
constr = String.Format("Provider=Microsoft.ACE.OLEDB.12.0;Data Source={0};Extended Properties='Excel 12.0 Xml;HDR=YES;IMEX=1'", excelFilePath)
Else
constr = String.Format("Provider=Microsoft.Jet.OLEDB.4.0;Data Source={0};Extended Properties='Excel 8.0;HDR=Yes;IMEX=1'", excelFilePath)
End If
Return constr
End Function
'将datatable导入到excel
Public Shared Function DataTable2Excel(dt As DataTable, excelFilePath As String) As Boolean
If File.Exists(excelFilePath) Then
Throw New Exception("该文件已经存在vb.net数独源码！")
End If
If dt.TableName.Trim.Length = 0 Or dt.TableName.ToLower = "table" Then
dt.TableName = "Sheet1"
End If
Dim colCount As Integer = dt.Columns.Count
Dim pa(colCount - 1) As OleDb.OleDbParameter
Dim tableStructStr As String = "Create Table "dt.TableName"("
Dim connString As String = buildConnStr(excelFilePath)
Dim objconn As New OleDbConnection(connString)
Dim objcmd As New OleDbCommand
objcmd.Connection = objconn
Dim dataTypeList As New ArrayList
dataTypeList.Add("System.Decimal")
dataTypeList.Add("System.Double")
dataTypeList.Add("System.Int16")
dataTypeList.Add("System.Int32")
dataTypeList.Add("System.Int64")
dataTypeList.Add("System.Single")
Dim i As Integer = 0
For Each col As DataColumn In dt.Columns
If dataTypeList.IndexOf(col.GetType.ToString)0 Then
pa(i) = New OleDbParameter("@"col.ColumnName, OleDbType.Double)
objcmd.Parameters.Add(pa(i))
If i + 1 = colCount Then
tableStructStr += col.ColumnName + " double)"
Else
tableStructStr += col.ColumnName + " double,"
End If
Else
pa(i) = New OleDbParameter("@"col.ColumnName, OleDbType.VarChar)
objcmd.Parameters.Add(pa(i))
If i + 1 = colCount Then
tableStructStr += col.ColumnName + " VarChar)"
