将EXCELL表格中的六列中的每一行的值都读出来,然后写入一个TXT文本文件中..
谢谢!!
首先在窗体上添加一个标签控件和一个命令按钮,然后在工程中添加对DAO引用。利用下面的程序代码就可将表中的数据导出到电子表格中。
Option Explicit
Private Sub Command1_Click()
Dim tempDB As Database
Dim i As Integer ' 循环计数器
Dim j As Integer
Dim rCount As Long ' 记录的个数
Dim xl As Object ' OLE自动化对象
Dim Sn As Recordset
Screen.MousePointer = 11
Label1.Caption = "打开数据库..."
Label1.Refresh
Set tempDB = Workspaces(0).OpenDatabase("Nwind.mdb")
Label1.Caption = "创建Excel对象..."
Label1.Refresh
Set xl = CreateObject("Excel.Sheet.8")
Label1.Caption = "创建快照型记录集..."
Label1.Refresh
Set Sn = tempDB.OpenRecordset("Customers", dbOpenSnapshot)
If Sn.RecordCount > 0 Then
Label1.Caption = "将字段名添加到电子表格中"
Label1.Refresh
For i = 0 To Sn.Fields.Count - 1
xl.Worksheets(1).cells(1, i + 1).Value = Sn(i).Name
Next
Sn.MoveLast
Sn.MoveFirst
rCount = Sn.RecordCount
' 在记录中循环
i = 0
Do While Not Sn.EOF
Label1.Caption = "Record:" & Str(i + 1) & " of" & _
Str(rCount)
Label1.Refresh
For j = 0 To Sn.Fields.Count - 1
' 加每个字段的值加到工作表中
If Sn(j).Type < 11 Then
xl.Worksheets(1).cells(i + 2, j + 1).Value = Sn(j)
Else
' 处理Memo和LongBinary 类型的字段
xl.Worksheets(1).cells(i + 2, j + 1).Value = "Memo or Binary Data"
End If
Next j
Sn.MoveNext
i = i + 1
Loop
' 保存工作表
Label1.Caption = "保存文件..."
Label1.Refresh
xl.SaveAs "c:\Customers.XLS"
'从内存中删除Excel对象
Label1.Caption = "退出Excel"
Label1.Refresh
xl.Application.Quit
Else
' 没有记录
End If
' 清除
Label1.Caption = "清除对象"
Label1.Refresh
Set xl = Nothing
Set Sn = Nothing
Set tempDB = Nothing
Screen.MousePointer = 0 ' 恢复鼠标指针
Label1.Caption = "Ready"
Label1.Refresh
End Sub
Private Sub Form_Load()
Label1.AutoSize = True
Label1.Caption = "Ready"
Label1.Refresh
