數據庫都需要輸出輸入，其實我們程序員的數據庫也是大同小異的，但是在ASP將Excel文件作為數據庫鏈接進行操作的方法，大家知道嗎？別著急，一起跟著錯新技術頻道小編來看看吧！
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 %> <!DOCTYPEHTMLPUBLIC"-//W3C//DTDHTML4.0Transitional//EN"> <HTML> <HEAD> <TITLE>NewDocument</TITLE> <METANAME="Generator"CONTENT="MicrosoftFrontPage5.0"> <METANAME="Author"CONTENT=""> <METANAME="Keywords"CONTENT=""> <METANAME="Description"CONTENT=""> </HEAD> <BODY> </BODY> </HTML> 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>上述代碼中
'objExcelApp.Quit 'set objExcelApp=Nothing
作為取消執行,因為此處不要關閉excel.applicaition,不然數據填完后,excel會關閉掉.這時在客戶端打開的excel文件需要由客戶進行修改或打印等操作。
以上就是錯新技術頻道小編帶來的ASP輸出excel文件實例講解，希望可以幫助你更加了解這些專業知識。
