SUMMARY
You can use data access objects (DAO) to programmatically link a Microsoft Excel spreadsheet using Microsoft Visual Basic for Applications code.



MORE INFORMATION
Microsoft provides programming examples for illustration only, without warranty either expressed or implied. This includes, but is not limited to, the implied warranties of merchantability or fitness for a particular purpose. This article assumes that you are familiar with the programming language that is being demonstrated and with the tools that are used to create and to debug procedures. Microsoft support engineers can help explain the functionality of a particular procedure, but they will not modify these examples to provide added functionality or construct procedures to meet your specific requirements. The following example uses DAO in a Visual Basic procedure to link a Microsoft Excel spreadsheet.  Start Microsoft Excel.  On Sheet1 of a new workbook, type the following in cells A1:C3:      A1: First   B1: Last    C1: Middle. A2: Adam   B2: Smith   C2: A.      A3: Bob     B3: Jones   C3: B.                     Save the workbook as LinkTest.xls in the folder My Documents. Close the workbook and quit Microsoft Excel. Start Microsoft Access and create a new database.  Create a new module and type the following procedure in it: Sub XLLink(strNewAccTable as string, strXLFileName as String, _          strImportSheet as String)

' Variables: '  strNewAccTable - the name of your new linked table. '  strXLFileName - the path and name of your Excel file. This '                  should be in the form "C:\MyDir\MyFile.xls." '  strImportSheet - the name of the sheet you want to link. ' All these variable are strings, and should be supplied to the ' subroutine enclosed in quotation marks.

On Error GoTo XLError

Dim db As DATABASE Dim td As TableDef

Set db = CurrentDb

' Create a new TableDef using the passed name. Set td = db.CreateTableDef(strNewAccTable)

' Set the ConnectString property to the Excel file to link. ' In Microsoft Access 7.0, the ConnectString needs to reflect the ' version of Excel. Remove the apostrophe from the Excel 5.0 ' line and comment out the Excel 8.0 line when working with ' Excel 5.0/95. ' td.Connect = "Excel 5.0;DATABASE=" & strXLFileName & ";" td.Connect = "Excel 8.0;DATABASE=" & strXLFileName & ";" td.SourceTableName = strImportSheet & "$"

' Append the new TableDef to the TableDefs collection. db.TableDefs.Append td

Exit_XLLink: Exit Sub

XLError: MsgBox Err.Number & " " & Err.Description Resume Exit_XLLink

End Sub </li> On the Debug menu, click Compile Loaded Modules.</li> On the Tools menu, click Debug Window.</li> In the Debug window, type:

XLLink "New Link", "C:\My Documents\LinkTest.xls", "Sheet1"

</li></ol>
