vb.net 怎么来回切换图片?

vb.net 怎么来回切换图片?1、添加控件Picturebox1和控件Timer1,将Timer1的Interval属性改为1000(即1秒),Enabled属性改为True

2、假设你要循环切换4张图片,你可以添加如下代码即可实现:

Dim a As Integer = 0

Private Sub Timer1_Tick(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Timer1.Tick

If a = 4 Then

a = 0

Else

a = a + 1

End If

If a = 0 Then Me.PictureBox1.Image = Image.FromFile("1.jpg")

If a = 1 Then Me.PictureBox1.Image = Image.FromFile("2.jpg")

If a = 2 Then Me.PictureBox1.Image = Image.FromFile("3.jpg")

If a = 3 Then Me.PictureBox1.Image = Image.FromFile("4.jpg")

End Sub

VB.NET 如何实现局域网内即时会话

楼主你好,你所指的那个指令就是"winchat",Windows自带的局域网聊天工具.使用方法:开始--运行--输入winchat,就可以打开Winchat了.只能实现很简单的功能,并且是中文,没什么好介绍的,相信你一看就懂,希望可以帮到你!

ps:你所说的电影是杜拉拉升职记吧?貌似那是用的邮件发的,不小心点成群发了~嘿嘿..

VB.NET容易做局域网简单的聊天工具吗?用TCP协议

Dim th As Threading.Thread

2 Dim tcpl As System.Net.Sockets.TcpListener

3

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

5 th = New System.Threading.Thread(New System.Threading.ThreadStart(AddressOf MyListen))

6 th.Start()

7 End Sub

8

9 Public Sub SendMessage()Sub SendMessage(ByVal IP As String, ByVal SendMsg As String)

10 Try

11 If IP "" Then

12 Dim tcpc As New System.Net.Sockets.TcpClient(IP, 5656)

13 Dim tcpStream As Net.Sockets.NetworkStream = tcpc.GetStream

14 Dim reqStream As New IO.StreamWriter(tcpStream)

15 reqStream.Write(SendMsg)

16 reqStream.Flush()

17 tcpStream.Close()

18 tcpc.Close()

19 End If

20 Catch ex As Exception

21 MsgBox(ex.Message.ToString)

22 End Try

23 End Sub

24 Private Sub MyListen()Sub MyListen()

25 Try

26 Dim ipAddress As System.Net.IPAddress = System.Net.Dns.Resolve(System.Net.Dns.GetHostName).AddressList(0)

27 tcpl = New System.Net.Sockets.TcpListener(ipAddress, 5656)

28 tcpl.Start()

29 While True

30 Dim s As System.Net.Sockets.Socket = tcpl.AcceptSocket()

31 Dim MyBuffer(1024) As Byte

32 Dim i As Integer

33 i = s.Receive(MyBuffer)

34 If i 0 Then

35 Dim lstrRec As String

36 Dim j As Integer

37 For j = 0 To i - 1

38 TextBox1.Text += Chr(MyBuffer(j)) ","

39 Next

40 End If

41 End While

42 Catch ex As Exception

43 MsgBox(ex.Message.ToString)

44 End Try

45 End Sub

46

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

48 SendMessage("192.168.0.61", TextBox2.Text)

49 End Sub

请教VB.NET的问题????????急!!

Imports System.Net.Socket

VB.NET 里面没有 Winsock 和 AxActiveMovie

这两个在 VB 6.0 里

VB.net Socket

麻烦给我发下vb2010下Socket类的使用方法,最好是有代码。就是怎样实现同一台电脑上两个程序的通讯,1窗体有按钮,文本框,2窗体有文本框,当单机1窗体的按钮时该窗体文本框的内容在2窗体的文本框中显示。。。十万火急啊。 邮箱523484850@qq.com

VB.NET中能否做一个像QQ那样的聊天框,可以输入文字和图片?

第一个问题 qq聊天室 必须能 用vb都可以做

第二个问题 vb.net插入数学公式 可以把这些公式封装到一个类中,调用就是了
