问题 I'm having a problem using OLDEDB from C# to write entries into an excel file. Essentially I want to use an excel template file for formatting some information. The idea is that users can run a query, it'll populate the results into an excel file, where the user can then continue to use excel to maniulate the results.

问题 I am configuring a dataset through the query wizard. I want to generate the parametrized query. My query looks like this: SELECT Field1, Field2, Field3 FROM SomeTable WHERE Field1 = @field1 The data is being fetched from an Access 2007 database, where this query executes successfully. From code however, I am getting the error: Error in WHERE clause near '@'. Unable to parse query text. How can I solve this? 回答1: Access doesn't support named parameters and uses ? instead of @ (like SQL-Server)

问题 I'm not sure why this is happening. I've seen the same issue online with little help out there to correct it. When i run my query inside Access i get different values ranging from 0 - 10 but for some reason, it won't return that same value inside my code. static int OrdersPerHour(string User) { int? OrdersPerHour = 0; OleDbConnection conn = new OleDbConnection(strAccessConn); DateTime curTime = DateTime.Now; try { string query = "SELECT COUNT(ControlNumber) FROM Log WHERE DateChanged > #" +

问题 So i think ive tried everything now. Im trying to get the values from radiobuttons and checkboxes from an excel sheet. My first approach was to use the Excel Data Reader: http://exceldatareader.codeplex.com/. The cells with checkboxes render empty. Same thing if i use OLEDB; string filename = @"C:\\" + "uploads\\SmartAuditSheet.xls"; string connectionString = "Provider=Microsoft.Jet.OLEDB.4.0;" + "Data Source=" + filename + ";" + "Extended Properties=Excel 8.0;"; OleDbDataAdapter dataAdapter

问题 I was trying to add a new row to the database using the below code. Even though the Rundef table has a primary key that should auto increment, it's value is always zero. Why does this happen? Private oRunDefDS As DataSet Dim oDR As DataRow = oRunDefDS.Tables("RunDef").NewRow() The design of the Rundef table: 回答1: When you create a new row in code it hasn't been inserted into the database yet. This means the database engine hasn't assigned it's incremental ID and gives it a default of 0
