vb.net編寫一個照片瀏覽器程序，程序執(zhí)行時單擊下一張，將會顯示下一張照片

我說選把打開多個圖片路徑加載到一個listbox里，利用listbox寫代碼

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

怎樣用vb.net做一個圖片瀏覽器？

在自定義工具箱中選擇dirlistbox，drivelistbox，filelistbox，添加這3個控件，然后在窗體上添加這些控件和一個picturebox控件，代碼如下：

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

你可以自己在修改下，這只是個模型，呵呵！

用vb.net如何編寫圖片瀏覽器的基本步驟功能是：圖片的打開、顯示、縮放、旋轉(zhuǎn)。

窗體上放一個PictureBox，兩個CommandButton，一個FileListBox

Private Sub Command1_Click()

If File1.ListIndex = 0 Then

ShowPic File1.ListCount - 1

Else

ShowPic File1.ListIndex - 1

End If

End Sub

Private Sub Command2_Click()

If File1.ListIndex = File1.ListCount - 1 Then

ShowPic 0

Else

ShowPic File1.ListIndex + 1

End If

End Sub

Private Sub Form_Load()

File1.Visible = False

File1.Pattern = "*.jpg;*.gif" '可以瀏覽的文件類型，使用分號隔開

File1.Path = App.Path '改成你需要瀏覽的目錄，比如"C:\Pic"

If File1.ListCount 1 Then '目錄中圖片在兩張以上可以瀏覽

ShowPic 0

Exit Sub

ElseIf File1.ListCount = 1 Then '目錄中只有一張圖片時只顯示這一張

ShowPic 0

End If

Command1.Enabled = False

Command2.Enabled = False

End Sub

Private Sub ShowPic(Index As Long)

File1.ListIndex = Index

Picture1.Picture = LoadPicture(File1.Path "\" File1.List(Index))

End Sub

如果對您有幫助，請記得采納為滿意答案，謝謝！祝您生活愉快！
