-- ListView显示文件问题
如下代码：
Dim path As String = "\\标准库\\冷却系列\\HASCO"
Dim lvw As WinForm.ListView = Forms("客户标准").controls("ListView1")
Dim ha As Integer = lvw.Position
lvw.Font = New Font("宋体", 12)\'设置字体型号与大小
lvw.StopRedraw() \'停止绘制
lvw.Groups.Clear() \'清除原来的分组
lvw.Columns.Clear() \'清除原来的列
lvw.Rows.Clear() \'清除原来的行
lvw.Images.Clear() \'清除原来的图片
lvw.View = ViewMode.Details \'显示模式为详细信息
lvw.Images.LargeSize = New size(32, 32)
Dim ics As String() = {"swf", "accdb", "mdb", "psd", "png", "xls", "xlsx", "bmp", "rar", "jpg", "doc", "docx", "zip", "pdf", "txt", "ppt", "pptx", "exe", "other", "dwg", "prt", "SLDPRT", "dxf", "eml", "stp", "step", "igs", "x_t"} \'定义扩展名数组
Dim kzms As String = "swf accdb mdb psd png xls xlsx bmp rar jpg doc docx zip pdf txt ppt pptx exe dwg prt SLDPRT dxf eml stp step igs x_t" \'定义已知扩展名的文本串
For Each ic As String In ics
lvw.Images.AddImage(ic, ic & ".png", ic & ".png") \'向listview里添加图标
Next
Dim cls() As String = {"序号", "文件名称", "图档上传日期", "大小"} \'定义列名
Dim wds() As Integer = {50, 350, 180, 150} \'定义列宽
For i As Integer = 0 To cls.Length - 1 \'增加列
Dim c As WinForm.ListViewColumn = lvw.Columns.Add()
c.Name = cls(i) \'指定列名
c.Text = cls(i) \'指定标题,这里标题和列名相同
c.Width = wds(i) \'指定列宽
Next
Dim dls As List(Of String)
dls = ftp.GetDetailList(path)
If dls.Count < = 0 Then
Dim r As WinForm.ListViewRow = lvw.Rows.Add() \'增加一行
r("文件名称") = "暂时没有文件"
Else
Dim dics As New SortedDictionary(Of String, String)
For Each dl As String In dls
Dim Parts() As String = dl.Split("*")
dics.Add(Parts(1) & dl, dl)
Next
Dim arr(dics.keys.count - 1) As String
dics.keys.copyto(arr, 0)
For i As Integer = arr.length - 1 To 0 Step - 1
Dim dl As String = dics(arr(i))
Dim Parts() As String = dl.Split("*")
Dim r As WinForm.ListViewRow = lvw.Rows.Add() \'增加一行
Dim Dot As Integer = parts(0).LastIndexOf(".") \'定义.的位置
Dim kzm As String = parts(0).SubString(Dot + 1) \'获取扩展名
\'
If kzms.Contains(kzm) = True Then \'若为已知扩展名
r.ImageKey = kzm \'指定行的图标键值
Else
r.ImageKey = "other"
End If
r("序号") = i + 1
r("文件名称") = Parts(0)
MessageBox.Show(Parts(0))
r("图档上传日期") = Parts(1)
If parts(2) > 1024 Then
r("大小") = format(parts(2) / 1048576, "0.0") & "MB"
Else
r("大小") = Parts(2) & "B"
End If
Next
