我要做一个用vb编写的图片浏览器，怎样使用定时器控件使其每间隔1000毫秒，就自动显示下一张图片？？？vb.net图片浏览器我的是VS2010的VB.Netvb.net图片浏览器，已经调试通过。
组成vb.net图片浏览器：一个窗体、一个PictureBox控件、一个ListBox控件、一个Timer控件
作用：把vb.net图片浏览器我的文档中图片文档的所有jpe和gif图片加载到ListBox控件中，然后Timer控件就每隔一秒读取ListBox中的图片路径文件名列表显示到PictureBox上。
代码：
Public Class Form1
Dim PicIndex As Long
Private Sub Form1_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
Me.ListBox1.Items.Clear()
Me.PictureBox1.ImageLocation = ""
For Each foundImage As String In _
My.Computer.FileSystem.GetFiles( _
My.Computer.FileSystem.SpecialDirectories.MyPictures, _
FileIO.SearchOption.SearchTopLevelOnly, "*.gif*", "*.jpg*")
Me.ListBox1.Items.Add(foundImage)
Next
If Me.ListBox1.Items.Count1 Then
MsgBox("There are no JPEG or GIF images in" _
" the Picture folder.")
End If
Me.PictureBox1.SizeMode = PictureBoxSizeMode.Zoom
Timer1.Enabled = True
Timer1.Interval = 1000
End Sub
Private Sub ListBox1_SelectedIndexChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles ListBox1.SelectedIndexChanged
Me.PictureBox1.ImageLocation = Me.ListBox1.SelectedItem
End Sub
Private Sub Timer1_Tick(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Timer1.Tick
If ListBox1.Items.Count1 Then Exit Sub
If PicIndexListBox1.Items.Count Then
Me.PictureBox1.ImageLocation = ListBox1.Items(PicIndex)
Me.Text = "当前图片路径和文件名: "ListBox1.Items(PicIndex)
PicIndex = PicIndex + 1
Else
PicIndex = 0
End If
End Sub
End Class
在vb.net下怎么制作一个图片浏览器，根据用户选择的文件夹，程序自动搜索改文件夹下的图片文件。Public Class Form1
Private TPS As Integer
Private TPPath() As String '定义不确定元素个数组，及动态数组
Private Sub LoadPhoto()
'将图片路径及图片名加载到数组
Dim JS As Integer '计数用
For Each foundFile As String In My.Computer.FileSystem.GetFiles(CurDir()"\职员图片")
TPS = TPS + 1 '将图片数存入变量中
Next
ReDim TPPath(TPS - 1) '确定数组大小
For Each FoundFile As String In My.Computer.FileSystem.GetFiles(CurDir()"\职员图片")
'将图片路径存入数组
TPPath(JS) = FoundFile
JS = JS + 1
Next
End Sub
Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
LoadPhoto()
End Sub
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
Label1.Text = TPPath.Length '获取数组大小
Label1.Text = TPPath(1) '获取数组中第2个元素的值
End Sub
vb.net编写一个照片浏览器程序，程序执行时单击下一张，将会显示下一张照片我说选把打开多个图片路径加载到一个listbox里，利用listbox写代码
Private Sub picbox_Click(ByVal sender As System.Object, ByVal e As System.EventArgs)
If ListBox1.SelectedIndex = count Then
Try
ListBox1.SelectedIndex = ListBox1.SelectedIndex + 1
Catch
ListBox1.SelectedIndex = 0
End Try
End If
picbox.Image = ListBox1.SelectedItem.ToString
End Sub
怎样用vb.net做一个图片浏览器？在自定义工具箱中选择dirlistboxvb.net图片浏览器，drivelistbox ， filelistbox，添加这3个控件，然后在窗体上添加这些控件和一个picturebox控件，代码如下vb.net图片浏览器：
Public Class Form1
Private Sub DirListBox1_SelectedIndexChanged(ByVal sender As Object, ByVal e As System.EventArgs) Handles DirListBox1.SelectedIndexChanged
FileListBox1.Path = DirListBox1.Path
End Sub
Private Sub DriveListBox1_SelectedIndexChanged(ByVal sender As Object, ByVal e As System.EventArgs) Handles DriveListBox1.SelectedIndexChanged
DirListBox1.Path = DriveListBox1.Drive
End Sub
Private Sub FileListBox1_SelectedIndexChanged(ByVal sender As Object, ByVal e As System.EventArgs) Handles FileListBox1.SelectedIndexChanged
PictureBox1.Image = Image.FromFile(FileListBox1.Path + "\" + FileListBox1.SelectedItem.ToString())
End Sub
End Class
