Accessing Excel Using ADO

I'm trying to access an Excel document as a database using ADO. I've found several snippets of code on the subject but I'm not having any luck getting it going. So far I am using just this fragment of code to connect but I'm getting an error that I don't know how to correct: Code: <? $conn = new COM("ADODB.Connection"); $dsn = "DRIVER={Microsoft.Jet.OLEDB.4.0}; DBQ=" . realpath("D:\public\testing\touchContactsWithTatumEmails.xls"); $conn->Open($dsn); ?> Error: Warning: Invoke() failed: Exception occurred. Source: Microsoft OLE DB Provider for ODBC Drivers Description: [Microsoft][ODBC Driver Manager] Data source name not found and no default driver specified in D:\public\testing\excelCOM.php on line 10 I'm not sure what I am doing wrong or how to correct it. If you have any information on this subject or have any ideas, I would be grateful for your input. -- Ron Herhuth -- Senior Developer -- ron.herhuth@tatumpartners.com
