Displaying an Excel Spreadsheet

  • 아티클

This lesson requires that you have Microsoft Excel installed on your system and is not supported on 64-bit platforms until Excel is developed for 64-bit platforms.

This lesson demonstrates how to display a Microsoft Excel spreadsheet in a Web page. As in the previous lesson, you use ADO. However, in this lesson you connect to an Excel spreadsheet instead of an Access database.

Prepare your Excel spreadsheet to display in an Active Server Page

  1. Using either Excel 98 or Excel 2000, create a spreadsheet and save it as ASPTOC.xls in x:\Inetpub\Wwwroot\Tutorial. Do not include any special formatting or column labels when creating the spreadsheet.

  2. Fill in some of the fields with random data. Treat the first row of cells as column names.

  3. Highlight the rows and columns on the spreadsheet that you want to display in the Web page. (Click one of the fields and drag your mouse diagonally to highlight a block of fields.)

  4. On the Insert menu, select Name, and click Define. This is where all your workbooks are defined by name and range of cells.

  5. Make sure the cell range you highlighted is displayed correctly at the bottom. Type the name MYBOOK for your workbook, and select Add. Whenever you change MYBOOK, make sure the correct cell range is displayed in the Refers to text box at the bottom of the Define Name window. Simply selecting MYBOOK after highlighting a new block of cells does not update the cell range.

  6. If the name shows up in the workbook list, click OK. Save your spreadsheet.

  7. Close Excel to remove the lock on the file so that your ASP page can access it.

In the examples in Lesson 3, you specified a provider name in the connection string, which maps to a specific ADO DLL. In this example, you use a driver name, which causes ASP to use the default provider for that driver name.

Copy and paste the following code in your text editor, and save the file as ViewExcel.asp in the x:\Inetpub\Wwwroot\Tutorial directory. View the example with your browser by typing https://localhost/Tutorial/ViewExcel.asp in the address bar.

   Set objConn = Server.CreateObject("ADODB.Connection")  
   objConn.Open strDriver  

   'Selects the records from the Excel spreadsheet using the workbook name you saved. 
   strSELECT = "SELECT * from `MYBOOK`"  

   'Create an instance of the ADO Recordset object, and connect it to objConn.

   Response.Write "<table border=1 ><tr>"  

   'For each column in the current row...  
   For i = 0 to (objRS.Fields.Count - 1)  
     ' write out the field name.  
     Response.Write "<td><font face=&quot;MS Gothic&quot;><B>" & objRS(i).Name & "</B></font></td>"  
   Next

       %><td><font face="MS Gothic"><%=objRS(i)%></font></td><%  
     Next  

     'Move to the next row.  
     objRS.MoveNext  

   Wend  

   Response.Write "</tr></table>" 

   'Close the Connection. 
   objConn.Close
