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
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 里面没有 Winsock 和 AxActiveMovie
这两个在 VB 6.0 里
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
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
