1:先想清楚,(包括先设想下页面,涉及的功能等)
2:编写文档
3:设计数据库,编写代码
4:
调试程序
,生成,查错
5:部署安装。
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
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
