用VB.NET制作图片浏览器时 ，打开图片文件时只能一张一张的打开，如何设置可以一次打开多个图片文件

Public Class Form1

Dim Files() As String

Dim ImgNum As Integer = 0

Dim CurIdx As Integer = 0

Sub OpenFiles()

InitialSet()

Try

If OpenFileDialog1.ShowDialog = Windows.Forms.DialogResult.OK Then

If Not OpenFileDialog1.FileNames Is Nothing Then

Files = OpenFileDialog1.FileNames

Else

Files(0) = OpenFileDialog1.FileName

End If

ImgNum = Files.Length

Dim s As String = String.Format("你共打开 {0} 张图片", ImgNum)

Me.Text = s

StateSet()

CurIdx = 1

DisplayImage(CurIdx)

Else

StateSet()

Me.PictureBox1.Image = Nothing

End If

Catch ex As Exception

MsgBox(ex.Message)

End Try

End Sub

Sub InitialSet()

Me.OpenFileDialog1.Multiselect = True

Me.OpenFileDialog1.Filter = "(*.jpg)|*jpg"

Me.OpenFileDialog1.FilterIndex = 0

ImgNum = 0

CurIdx = 0

If Not Files Is Nothing Then

Array.Clear(Files, 0, Files.Length - 1)

End If

End Sub

Sub DisplayImage(ByRef Idx As Integer)

If IO.Path.GetExtension(Files(Idx - 1)).ToLower = ".jpg" Then

Me.PictureBox1.Load(Files(Idx - 1))

End If

StateSet()

End Sub

Sub StateSet()

If ImgNum 1 Then

Me.btnNext.Enabled = True

Else

Me.btnNext.Enabled = False

Me.btnPervious.Enabled = False

Exit Sub

End If

If CurIdx 1 And ImgNum 1 Then

End If

End Sub

Sub NextIamge(ByRef Idx As Integer)

If Idx ImgNum Then

Idx += 1

Else

Exit Sub

End If

DisplayImage(Idx)

End Sub

Sub PerviousIagme(ByRef Idx As Integer)

If Idx 1 Then

Idx -= 1

Else

Exit Sub

End If

DisplayImage(Idx)

End Sub

Private Sub btnNext_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnNext.Click

Try

NextIamge(CurIdx)

Catch ex As Exception

MsgBox(ex.Message)

End Try

End Sub

Private Sub btnOpen_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnOpen.Click

OpenFiles()

End Sub

VB.NET如何装载一个文件夹的所有图片 就是FolderBrowserDialog选定一个文件夹 自动装载里面所有图片

‘ 导入图片按钮

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

FolderBrowserDialog1.Description = "选择图片文件夹导入图片"

FolderBrowserDialog1.ShowDialog()

path = FolderBrowserDialog1.SelectedPath()

If path = "" Then Return

strSrcFile = Dir(path "\*.tif")

PictureBox1.Image = Image.FromFile(path "\" strSrcFile)

dirFiles.Add(path "\" strSrcFile)

FileNames.Add(strSrcFile)

Do

strSrcFile = Dir()

dirFiles.Add(path "\" strSrcFile)

If (strSrcFile IsNot Nothing) Then

FileNames.Add(strSrcFile)

End If

Loop Until Len(strSrcFile) = 0

End Sub

’ 上一张图片（我做的按钮，鼠标左键的话原理也是一样 的，你放到鼠标左键事件中就可以了）

Private Sub Button6_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button6.Click '向前

If path "" Then

If (saveDirFiles.Count = 0) Then

Return

End If

MyPos = 0

PictureBox1.Image = Image.FromFile(saveDirFiles(saveDirFiles.Count - 1).ToString())

dirFiles.Insert(0, saveDirFiles(saveDirFiles.Count - 1).ToString())

saveDirFiles.RemoveAt(saveDirFiles.Count - 1)

End If

End Sub

’ 下一张图片

Private Sub Button7_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button7.Click '向后

If path "" Then

If (dirFiles.Count = 0) Then

Return

End If

MyPos = 0

Dim iCurrentPos As Integer = 0

Try

PictureBox1.Image = Image.FromFile(dirFiles(iCurrentPos + 1).ToString())

Catch ex As Exception

MsgBox("已翻至图片的最后一页")

Return

End Try

saveDirFiles.Add(dirFiles(iCurrentPos))

dirFiles.RemoveAt(iCurrentPos)

End sub

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

在VB.NET中浏览图片

转换成位图肯定是可以浏览的，WMF文件没试过。

你可以将图片以二进制形式存储在数据库中，如果是SQL Server，对应字段的类型应该是image。
