问题 I am trying the following solution and not having much luck: How can i update app.config connectionstring Datasource value in C#? The code I have is: Configuration config = ConfigurationManager.OpenExeConfiguration(ConfigurationUserLevel.None); // Because it's an EF connection string it's not a normal connection string // so we pull it into the EntityConnectionStringBuilder instead EntityConnectionStringBuilder efb = new EntityConnectionStringBuilder( config.ConnectionStrings

问题 I'm very new to SQL Server, Flot.js, working with databases in general. I'm working on a project in ASP.NET MVC 4 (using VS 2012) which has a Microsoft SQL Server Compact 4.0 database filled with data, and I would like to visually display this data using flot.js. I haven't been able to find any information on the general steps one would take to manipulate the data. Starting with the DB entries in the SQL CE database, and ending with a JSON file (or a CSV - anything flot.js could use as input)

问题 I have an app that uses the OdbcConnection classes to connect to Oracle and Sql Server. Works great. But I'm writng some tests and want to connect to Sql Serve CE, which is built into VS2010. What is the connection string to use? This fails: Data Source=Testing.sdf 回答1: There is no ODBC provider for SQL CE so no kind of connection string will work for you.

问题 I am experiencing some strange behavior with SQL Server CE 3.5 SP2. I have a table with 2 columns; one of type int named ID, which is the primary key, and one of type ntext named 'Value'.

I have 2 test projects (one for Effort and the other for SQL CE). If I'm running both separately everthing's fine.
