This application works reliably most of the time. Recently, the application has begun intermittently throwing "System.Data.OleDb.OleDbException: Unspecified error" when the OleDbConnection.Open() method is called. The error continues until the application pool is recycled, at which time everything functions as expected again. No errors are captured within the Windows Application event log. The ASP.NET web application is hosted within web parts in WSS 3.0 on a Windows Server 2003 32 bit machine. Any insight would be much appreciated. We are using the following code to retrieve data from an Excel 2003 file: public static DataTable GetWorksheetData(string filePath) { OleDbConnectionStringBuilder builder = new OleDbConnectionStringBuilder { DataSource = filePath }; builder.Provider = "Microsoft.Jet.OLEDB.4.0"; builder["Extended Properties"] = "Excel 8.0;IMEX=1;HDR=YES"; DataTable table = new DataTable(); try { // Creates an OleDbConnection for the excel file using (OleDbConnection connection = new OleDbConnection(builder.Connec

The upload and writing of the file to the file system works fine but I get an error when trying to open the file on our production server only. The application works fine on two other servers (development and testing servers). The following code generates an 'Unspecified Error' in the Exception.Message.

See more: C# .NET MS-Excel Errors Hello All, I have an application that reads an excel file(.xls) but occasionally an error is thrown: Unspecified Error. I use an OleDbConnection to open a connection. OleDbCommand to execute a query. And DbDataReader to read the rows. My program logic is like this: 1. Open the excel file 2. Read each row 3. Validate each column - some validation may require opening the connection again 4. Save it to the database when no errors occur When I upload a small file(less than 70 rows) the error is never thrown. But when I upload a large file(71 rows and above)the error shows. This is where the error occur: string myconnection1 = @"provider=Microsoft.Jet.OLEDB.4.0; data source=" + _excelFile + ";Extended Properties='Excel 8.0;IMEX=1';"; OleDbConnection Connection1 = new OleDbConnection(myconnection1); OleDbCommand mycommand1 = new OleDbCommand("Select * FROM [MASTERLIST FORMAT$] where F6 = '" + _insured.StrDepLname + "' and F7 = '" + _insured.StrDepFname + "' and F8 = '" +
