Q1: 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.Count 1 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.Count 1 Then Exit Sub

If PicIndex ListBox1.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

Q2: 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

Q3: 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

Q4: 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
