在asp中利用excel的一个方法是将excel文件作为一个数据库进行链接,然后的操作和对access数据库操作类似.但是这个方法不是总能有用的，应为excel不是关系型的数据库。对于一个固定格式,这个格式里有复杂的单元格合并,边框线条样式,还有图案,单元格之间还有公式关系等等的,我想最容易理解的就是在后台打开一个已有设定好模板的文件,然后在需要的地方插入数据,保存,输出... ... 这里提到的这种方法是直接建立一个excel对象,在后台可以更方便的对excel文档进行各种操作。 服务器端还必须要设置的一点是COM组件的操作权限。在命令行键入“DCOMCNFG”，则进入COM组件配置界面，选择MicrosoftExcel后点击属性按钮，将三个单选项一律选择自定义，编辑中将Everyone加入所有权限。保存完毕后重新启动服务器。 很重要.不设置的话,别的电脑将无法完成excel对象的建立.

操作完excel文件需要将文件进行输出,实际弄一下,用ASP的redirect到excel方法,有时候是在IE中直接打开,有时候是弹出"下载 打开 保存"窗口.如果需要直接在IE中打开,不放用FSO载入excel文件,然后在IE中输出.

Dim Fso,FileExt,strFilePath,Mime
strFilePath = "f:\aspxuexi.doc"
Set Fso=Server.CreateObject("Scripting.FileSystemObject")
FileExt = Fso.GetExtensionName(strFilePath)
Set fso=Nothing
Select Case FileExt
Case "doc"
Mime="Application/msword"
Case "xls"
Mime="Application/msexcel"
End Select
Call OutPut(strFilePath,Mime)
'######################################################
Function OutPut(strFilePath,Mime)

Const adTypeBinary = 1
Set objStream = Server.CreateObject("ADODB.Stream")
objStream.Open
objStream.Type = adTypeBinary
objStream.LoadFromFile strFilePath
Response.BinaryWrite objStream.Read
objStream.Close

在实际应用中.当服务器端正在运行excel或ACCESS程序时,客户端提交建立excel.application对象无法成功.另一种情况,当一个客户端提交请求时,并没有结束时,另一个客户端提交的请求也无法成功!或许这个问题有别的解决方案,但是至少这是不稳定的.
<script language="vbscript">
set objExcelApp=CreateObject("Excel.Application")
objExcelApp.DisplayAlerts=true
objExcelApp.WorkBooks.Open("http://XXX.XXX.XXX/XXX.xls")
'完整网路地址的xls文件,这个文件已经设置好格式及打印样式,保存在服务器上
set objExcelBook=objExcelApp.ActiveWorkBook
set objExcelSheets=objExcelBook.Worksheets
set objExcelSheet=objExcelBook.Sheets(1)
'====此处为对excel单元格进行填写数据的语句,如果是从数据库提取数据,可由后台程序生成这些语句,ASP中的示列:
'如:response.write "objExcelSheet.Range(""B2"").Value="""&rs("XXX")&""""
'或 objExcelSheet.Range("B2").Value="<%=rs("XXX")%>"
objExcelSheet.Range("B2:k2").Value=Array("Week1","Week2","Week3","Week4","Week5","Week6","Week7")
objExcelSheet.Range("B3:k3").Value=Array("67","87","5","9","7","45","45","54","54","10")
objExcelSheet.Range("B4:k4").Value=Array("10","10","8","27","33","37","50","54","10","10")
objExcelSheet.Range("B5:k5").Value=Array("23","3","86","64","60","18","5","1","36","80")
objExcelSheet.Cells(3,1).Value="InternetExplorer"
objExcelSheet.Cells(4,1).Value="Netscape"
objExcelSheet.Cells(5,1).Value="Other"
'==================
'objExcelApp.Quit
'set objExcelApp=Nothing
</script>
上述代码中 'objExcelApp.Quit 'set objExcelApp=Nothing 作为取消执行,因为此处不要关闭excel.applicaition,不然数据填完后,excel会关闭掉.这时在客户端打开的excel文件需要由客户进行修改或打印等操作。 以上就是利用ASP输出excel文件的全部过程，希望对大家的学习有所帮助。 |
