PictureViewer控件后面的管理栏能否隐藏，只显示红色框内部分？

此主题相关图片如下：0098.gif

或是PictureBox能否显示多张图片？

方法一：你可以把控件放在一个panel里面，然后控制panal的高度，不就行了？

方法二：你可以隐藏按钮 http://www.foxtable.com/webhelp/scr/2286.htm

方式三：

Dim obj1 As object = e.Form.Controls("PictureViewer1").basecontrol.Controls(0)
obj1.panel2.controls("FlowLayoutPanel2").visible = False

有多张的图片，做个上一张，下一张的按钮，怎么去判断上一张，下一张呢？

上一行的代码，参考

Dim obj As object = Forms("窗口2").Controls("PictureViewer1").basecontrol.Controls(0)
Dim pic As Object = obj.panel1.controls("PictureSplitContainer").Panel1.controls("panel2").controls("C1PictureBox1")
Dim r As Row = Tables("表A").current
Dim ls As List(Of String) = r.DataRow.Lines("第一列")
Dim piv As WinForm.PictureViewer = Forms("窗口2").Controls("PictureViewer1")
Dim str As String = FileSys.GetName(piv.SelectedItem)
If vars("str") <> str Then
    vars("str") = str
    vars("idx") = -1
End If
If vars("idx") = -1 Then
    For i As Integer = 0 To ls.count-1
        If ls(i).Contains(vars("str")) Then
            If i = ls.count-1 Then
                pic.image = getimage(ProjectPath & "attachments/" & ls(0))
                vars("idx") = 0
            Else
                pic.image = getimage(ProjectPath & "attachments/" & ls(i+1))
                vars("idx") = i+1
            End If
        End If
    Next
ElseIf vars("idx") = ls.count-1
    pic.image = getimage(ProjectPath & "attachments/" & ls(0))
    vars("idx") = 0
Else
    pic.image = getimage(ProjectPath & "attachments/" & ls(vars("idx")+1))
    vars("idx") += 1
End If
