VB.net做一个小程序 求教

Private Sub Form1_Load(sender As Object, e As EventArgs) Handles MyBase.Load

Dim oleDbConnection1 As OleDb.OleDbConnection

Dim oledbDataAdapter As OleDb.OleDbDataAdapter

Dim oledbData As DataSet = New DataSet

Dim strConnect As String = "Provider= OraOLEDB.Oracle;Data Source=888;User ID=888;Password=888;"

oleDbConnection1 = New System.Data.OleDb.OleDbConnection(strConnect)

Dim strSql As String

strSql = "select *" " from xx"

Dim oledbCommand As OleDb.OleDbCommand

oledbCommand.CommandText = strSql

oledbCommand.CommandType = CommandType.Text

oledbCommand.Connection = oleDbConnection1

oledbDataAdapter.SelectCommand = oledbCommand

oleDbConnection1.Open()

oledbDataAdapter.Fill(oledbData, "gy_bingrenxx")

oleDbConnection1.Close()

'在窗体上添加一个DataGridView控件,在这个位置加一句代码

DataGridView1.DataSource = oledbDataAdapter.Tables("gy_bingrenxx")

End Sub

求写一个VB.Net小程序

随机生成2-5阶方阵：

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

Dim d(,) As Integer

Dim n As Integer

Dim i As Integer

Dim j As Integer

Randomize()

n = Int(4 * Rnd() + 2)

ReDim d(n, n)

Label1.Text = ""

For i = 1 To n

For j = 1 To n

d(i, j) = Int(Rnd() + 0.5)

Label1.Text = Label1.Text d(i, j) " "

Next

Label1.Text = Label1.Text vbCrLf

Next

End Sub
