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

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()

'在窗體上添加一個DataGridView控件,在這個位置加一句代碼

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

End Sub

vb.net的小程序

你要做一個考試系統(tǒng)？？這可不是小程序，不過如果是超精簡的話，我倒可以寫個思路給你。

在form添加一個label 和四個command1(組成一個控件組修改index屬性，按順序設置為ABCD)和一個command2(可要可不要，這個是作為跳過用的)

定義全局變量 questions() as string,questionid as integer，answers() as string

在form_load中，將問題和答案讀入questions()和answers()中，然后將第一個問題顯示在label中，設置questionid=1

之后在command1_click(index as integer)中用select語句根據questionid將答案和回答比較，然后顯示下一題，同時更改questionid。。。大概就這樣

command2_Click()就直接顯示下一題和更改questionid

問題結束后就OK了，之后要加什么可以自己加上去~
