vblistview导出数据(vb中list)
vb listview 导出问题
Private Sub Command1_Click()
For i = 1 To ListView1.ListItems.Count
If Val(ListView1.ListItems(i).SubItems(1)) 10 Then
'导出到文本框中
Text1.Text = Text1.Text ListView1.ListItems(i).Text "(" ListView1.ListItems(i).SubItems(1) ")" vbCrLf
'导出到listbox中
List1.AddItem ListView1.ListItems(i).Text "(" ListView1.ListItems(i).SubItems(1) ")"
End If
Next i
End Sub
'以下是测试时用的.
Private Sub Form_Load()
ListView1.View = lvwReport
ListView1.ColumnHeaders(1).Text = "姓名"
ListView1.ColumnHeaders(2).Text = "成绩"
Dim a()
a() = Array("aaa", " 16", "bbb", "8", "ccc", "13", "ddd", "11", "zzz", " 5", "eee", "6")
For i = 0 To UBound(a) - 1 Step 2
Set lv = ListView1.ListItems.Add(, "a" CStr(i), a(i), 1)
lv.SubItems(1) = a(i + 1)
Next i
End Sub
VB中listview导出excel?
For i = 1 To Me.ListView1.ListItems.Count - 1
xl.Range("A" i + 1).Value = Me.ListView1.ListItems(i).Text
xl.Range("B" i + 1).Value = Me.ListView1.ListItems(i).SubItems(1)
xl.Range("C" i + 1).Value = Me.ListView1.ListItems(i).SubItems(2)
xl.Range("D" i + 1).Value = Me.ListView1.ListItems(i).SubItems(3)
xl.Range("E" i + 1).Value = Me.ListView1.ListItems(i).SubItems(4)
xl.Range("F" i + 1).Value = Me.ListView1.ListItems(i).SubItems(5)
xl.Range("G" i + 1).Value = Me.ListView1.ListItems(i).SubItems(6)
xl.Range("H" i + 1).Value = FormatStr(Me.ListView1.ListItems(i).SubItems(7))
Next i
xl.Visible = True
VB listview 导出到excel很慢
你可以使用数据库插入,VB用ADO连接那个空EXCEL,用sql语然插入,就很快了。
[vb.net] 怎么把listview中数据 导出保存到成excel文件
我回答你的第一个问题,因为后面的看不懂你的意思
函数:
Public Function ListViewtoExcel(ByVal LV As ListView) As Boolean
Try
If LV.Items.Count = 0 Then '判断记录数,如果没有记录就退出
MessageBox.Show("没有记录可以导出", "没有可以导出的项目", MessageBoxButtons.OK, MessageBoxIcon.Information)
Return False
End If
'如果有记录就导出到Excel
Dim AP_Excel As Object '定义Excel对象
Dim wk As Object '定义Workbook对象
AP_Excel = CreateObject("Excel.Application") '创建Excel对象
wk = AP_Excel.workbooks.add()
Dim i As Integer, u As Integer = 0, v As Integer = 0 '定义循环变量,行变量,列变量
For i = 1 To LV.Columns.Count '把表头写入Excel
wk.worksheets(1).cells(1, i) = LV.Columns(i - 1).Text.Trim
Next
Dim str(LV.Items.Count - 1, LV.Columns.Count - 1) '定义一个二维数组
For u = 0 To LV.Items.Count - 1 '行循环
For v = 0 To LV.Columns.Count - 1 '列循环
If v LV.Items(u).SubItems.Count Then '如果该行该列项存在
str(u, v) = LV.Items(u).SubItems(v).Text.Trim
Else '如果该行该列项不存在
str(u, v) = ""
End If
Next
Next
wk.worksheets(1).range("A2").Resize(LV.Items.Count, LV.Columns.Count).Value = str '把数组一起写入Excel
wk.worksheets(1).Cells.EntireColumn.AutoFit() '自动调整Excel列
' yy.worksheets(1).name = LV.TopLeftHeaderCell.Value.ToString '表标题写入作为Excel工作表名称
AP_Excel.visible = True '设置Excel可见
wk = Nothing '销毁组建释放资源
AP_Excel = Nothing '销毁组建释放资源
Return True '返回真
Catch ex As Exception '错误处理
MessageBox.Show(Err.Description.ToString, "错误", MessageBoxButtons.OK, MessageBoxIcon.Error) '出错提示
Return False '返回假
End Try
End Function
调用函数:如 ListViewtoExcel(Me.ListView1)
