利用OWC建立EXECL的例子
类别: 数据库教程
呵呵,这个是我介绍制作EXECL的第三种方法了,对于OWC,我在前面的文章里也已经有所介绍,废话少说,请看代码:
<%
Option Explicit
Class ExcelGen
Private objSpreadsheet
Private iColOffset
Private iRowOffset
Sub Class_Initialize()
Set objSpreadsheet = Server.CreateObject("OWC.Spreadsheet")
iRowOffset = 2
iColOffset = 2
End Sub
Sub Class_Terminate()
Set objSpreadsheet = Nothing \'Clean up
End Sub
Public Property Let ColumnOffset(iColOff)
If iColOff > 0 then
iColOffset = iColOff
Else
iColOffset = 2
End If
End Property
Public Property Let RowOffset(iRowOff)
If iRowOff > 0 then
iRowOffset = iRowOff
Else
iRowOffset = 2
End If
End Property
Sub GenerateWorksheet(objRS)
\'Populates the Excel worksheet based on a Recordset\'s contents
\'Start by displaying the titles
If objRS.EOF then Exit Sub
Dim objField, iCol, iRow
iCol = iColOffset
iRow = iRowOffset
For Each objField in objRS.Fields
objSpreadsheet.Cells(iRow, iCol).Value = objField.Name
iCol = iCol + 1
Next \'objField
\'Display all of the data
Do While Not objRS.EOF
iRow = iRow + 1
iCol = iColOffset
For Each objField in objRS.Fields
If IsNull(objField.Value) then
objSpreadsheet.Cells(iRow, iCol).Value = ""
Else
objSpreadsheet.Cells(iRow, iCol).Value = objField.Value
End If
iCol = iCol + 1
Next \'objField
objRS.MoveNext
Loop
End Sub
Function SaveWorksheet(strFileName)
\'Save the worksheet to a specified filename
On Error Resume Next
Call objSpreadsheet.ActiveSheet.Export(strFileName, 0)
SaveWorksheet = (Err.Number = 0)
End Function
End Class
%>
<%
Dim objRS
Set objRS = Server.CreateObject("ADODB.Recordset")
objRS.Open "SELECT * FROM titles", "DSN=FooBar"
Dim objExcel
Set objExcel = New ExcelGen
objExcel.RowOffset = 4
objExcel.ColumnOffset = 1
objExcel.GenerateWorksheet(objRS)
If objExcel.SaveWorksheet(Server.MapPath("foo.xls")) then
Response.Write "Worksheet saved. <a href=""foo.xls"">Download</a>"
Else
Response.Write "Error in saving worksheet!"
End If
Set objExcel = Nothing
objRS.Close
Set objRS = Nothing
%>
注意:请注意权限的问题……经常有人发EMAIL给我关于这方面的问题,实际上你只要给iuser_machine以适当的权限就可以了,比如对存放在EXECL文件的地方要有写的权限
:),下次我看看会再介绍一种生成EXECL的方法,可以利用BCP做的。
