oledbconnection

I am using an OleDbConnection, OldDbCommand, and OleDbReader against an Access database. I have a named query in the database which I am calling from the code. The query works correctly when it is ran from access. Several resources indicate the error could be caused by using reserved words in the query and to wrap them with brackets. I am not using any reserved words and have wrapped all column names in brackets anyway to rule it out. Trying to determine where the problem is, I have simplified the query to a simple SELECT id FROM table1 WHERE id = 5 which the Ole connection does not throw an

I'm using the OleDbConnection class to retrieve data from an Excel 2000/2003 workbook: string connectionString = "Provider=Microsoft.Jet.OLEDB.4.0;" + "Data Source=" + filename + ";" + "Extended Properties=\"Excel 8.0;IMEX=1\";"; OleDbConnection connection = new OleDbConnection(connectionString); connection.Open(); // code to get table name from schema omitted var dataAdapter = new OleDbDataAdapter(string.Format("SELECT * FROM [{0}]", name),connection); var myDataSet = new DataSet(); dataAdapter.Fill(myDataSet, "ExcelInfo"); Now it turns out that cells in the worksheet with length greater than

I currently have a handler which takes the filepath and tabname for an excel file, processes the file into a datatable and then serializes the table into a json string to return. This is working until I try to process large file, and then I get an out of memory exception. I was thinking that it would reduce the memory usage if I didn't load everything into the datatable first, and instead loaded straight into the json string. However, I have been unable to find any examples of how to do this. Can I serialize directly from the OleDbConnection into a string? How? public void ProcessRequest

The problem i'm having is that the data adapter is looking at only the first row in each column to determine the data type. In my case the first column "SKU" is numbers for the first 500 rows then I happen to have SKU's which are mixed numbers and letters. So what ends up happening is rows in the SKU column are left blank, but I still get the other information for each column row. I believe it is the connection string that controls that and with my current settings it should work, however it is not. Connection String: conn.ConnectionString = @"Provider=Microsoft.ACE.OLEDB.12.0;Data Source=C:

I know this topic is done to death but I am at wits end. I need to parse a csv. It's a pretty average CSV and the parsing logic has been written using OleDB by another developer who swore that it work before he went on vacation :) CSV sample: Dispatch Date,Master Tape,Master Time Code,Material ID,Channel,Title,Version,Duration,Language,Producer,Edit Date,Packaging,1 st TX,Last TX,Usage,S&P Rating,Comments,Replace,Event TX Date,Alternate Title ,a,b,c,d,e,f,g,h,,i,,j,k,,l,m,,n, The problem I have is that I get various errors depending on the connection string I try. when I try the connection
