n=6

Console.WriteLine("{0}!={1}",n,fact(n))

n=10

For i As Integer=1 To n

Console.Write("{0}{1}",fibo(i),IIF(n=i,vbCrLf,","))

Next

Console.Write("按任意键继续。。。 ")

Console.ReadKey(True)

End Sub

' 递归算阶乘

Function fact(n As Long) As Long

If 0=n OrElse 1=n Then Return 1

Return n*fact(n-1)

End Function

' 递归算斐波那契数列

Function fibo(n As Long) As Long

If 1=n OrElse 2=n Then Return 1

Return fibo(n-1)+fibo(n-2)

End Function

VB.NET中的代码

大概的过程:

Imports System.Data

Imports System.Data.SqlClient

--------------

Dim a As New SqlDataAdapter

Dim con As SqlConnection

con = New SqlConnection( "Persist Security Info=False;Integrated Security=SSPI;database=northwind;server=.;Connect Timeout=30")

con.Open()

a.SelectCommand = New SqlCommand("select * from table where c=1", con)

a.UpdateCommand = New SqlCommand("update table set b=2 where c=1", con)

a.DeleteCommand = New SqlCommand("delete from table where c=1", con)

a.InsertCommand = New SqlCommand("insert into table values (1,2,3)", con)

a.SelectCommand.ExecuteNonQuery()

a.UpdateCommand.ExecuteNonQuery()

a.DeleteCommand.ExecuteNonQuery()

a.InsertCommand.ExecuteNonQuery()

con.Close()

a.Dispose()

跪求vb.net代码

新建窗口,添加picture控件

利用line()方法画线

line(开始x坐标,开始y坐标)-(结束x坐标,结束y坐标),线的颜色,画线的方式(默认为线,B为矩形无填充,BF为填充的矩形)

For i = 1 To 16

Picture1.Line (0, Picture1.Height / 2)-(i * (Picture1.Width / 16), 0), RGB(255, 0, 0)

Picture1.Line (0, Picture1.Height / 2)-(i * (Picture1.Width / 16), Picture1.Height), RGB(255, 0, 0)

Picture1.Line (Picture1.Width, Picture1.Height / 2)-(i * (Picture1.Width / 16), 0), RGB(0, 255, 0)

Picture1.Line (Picture1.Width, Picture1.Height / 2)-(i * (Picture1.Width / 16), Picture1.Height), RGB(0, 255, 0)

Next i

如果要在窗口上画也可以调用窗口的line方法即form.line()
