這篇文章主要內容是利用ASP輸出excel文件實例講解，感興趣的小伙伴們可以參考一下

在asp中利用excel的一個方法是將excel文件作為一個數據庫進行鏈接,然后的操作和對access數據庫操作類似.但是這個方法不是總能有用的，應為excel不是關系型的數據庫。對于一個固定格式,這個格式里有復雜的單元格合并,邊框線條樣式,還有圖案,單元格之間還有公式關系等等的,我想最容易理解的就是在后臺打開一個已有設定好模板的文件,然后在需要的地方插入數據,保存,輸出... ...

這里提到的這種方法是直接建立一個excel對象,在后臺可以更方便的對excel文檔進行各種操作。

服務器端還必須要設置的一點是COM組件的操作權限。在命令行鍵入“DCOMCNFG”，則進入COM組件配置界面，選擇MicrosoftExcel后點擊屬性按鈕，將三個單選項一律選擇自定義，編輯中將Everyone加入所有權限。保存完畢后重新啟動服務器。

很重要.不設置的話,別的電腦將無法完成excel對象的建立.

但是這種方法也有一個缺憾,在我實際操作中,如果服務器上已有打開的excel文件,再執行同一文件,就會出錯.暫時還搞不明白為何.可能還有一些地方沒設置好吧.

另外,上面引用的文章中實例代碼格式不太完整,其中很多換行和空格格式不準確,如果代碼完整,只要復制代碼,就可以運行成功,然后再慢慢進行研究修改,就很容易上手了.現把修改后的代碼如下(刪去了其中畫圖表的部分):

程序代碼：

<%

On Error Resume Next

strAddr=Server.MapPath(".")

set objExcelApp=CreateObject("Excel.Application")

objExcelApp.DisplayAlerts=false

objExcelApp.Application.Visible=false

objExcelApp.WorkBooks.Open(strAddr&"/Templet/Null.xls")

set objExcelBook=objExcelApp.ActiveWorkBook

set objExcelSheets=objExcelBook.Worksheets

set objExcelSheet=objExcelBook.Sheets(1)

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"

objExcelSheet.Range("b2:k5").Select

SaveAs(strAddr&"/Temp/Excel.xls")

objExcelApp.Quit

set objExcelApp=Nothing

操作完excel文件需要將文件進行輸出,實際弄一下,用ASP的redirect到excel方法,有時候是在IE中直接打開,有時候是彈出"下載打開保存"窗口.如果需要直接在IE中打開,不放用FSO載入excel文件,然后在IE中輸出.

程序代碼:

<%

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)

Response.ContentType = Mime

Const adTypeBinary = 1

Set objStream = Server.CreateObject("ADODB.Stream")

objStream.Open

objStream.Type = adTypeBinary

objStream.LoadFromFile strFilePath

Response.BinaryWrite objStream.Read

objStream.Close

Set objStream = Nothing

End Function

'######################################################

%>

在實際應用中.當服務器端正在運行excel或ACCESS程序時,客戶端提交建立excel.application對象無法成功.另一種情況,當一個客戶端提交請求時,并沒有結束時,另一個客戶端提交的請求也無法成功!或許這個問題有別的解決方案,但是至少這是不穩定的.

正好我們部門內部網上有相關成功的例子,挖出來看,原來是在客戶端建立excel.application的.這樣,服務器端不會再沖突.對于客戶端,因為是在局域網內運行,客戶IE安全級別可以設低,并允許運行相關activeX(就是在IE工具選項中把各類涉及安全的東西都設為允許,具體的哪一項沒有去追究),即使沒有設置,IE也會彈出警告窗口:"是否允許運行activeX?"

實現的代碼和上篇日志差不多,簡單的如下:

程序代碼:

<script language="vbscript">

set objExcelApp=CreateObject("Excel.Application")

objExcelApp.DisplayAlerts=true

objExcelApp.WorkBooks.Open("http://XXX.XXX.XXX/XXX.xls")

'完整網路地址的xls文件,這個文件已經設置好格式及打印樣式,保存在服務器上

set objExcelBook=objExcelApp.ActiveWorkBook

set objExcelSheets=objExcelBook.Worksheets

set objExcelSheet=objExcelBook.Sheets(1)

'====此處為對excel單元格進行填寫數據的語句,如果是從數據庫提取數據,可由后臺程序生成這些語句,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>
