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'. The 'Value' column is supposed to contain rather long string values. However, when I try to store a string that is longer than 4000 characters, the v...
I am writing a SQL Compact database app with an SDF database that I need to install on the user's machine. The user needs to be able to read and write to the database, and the database needs to be available to all users. The app has to run with normal user rights, and UAC can't be disabled. Where is the best place to place the database ...

Here is the code I...

The new data types in SQL Server 2008 are mapped to nchar, nvarchar, image, etc. F...
I am writing some code to store names in a database. I limit the names to only certain characters, but last names are a challenge. Since some people have single quotes in their name (example O'Brian) I need to allow this. So I wrote a regex replace to replace the ' with a \' which I assumed should make the ' a literal. It works as far...

Essentially we want to push around arbitrary flat typed datasets of under 4 Gb each and have a good editing experience for manipulating this data.

All I want to do is insert a record into my table which is in a SQL Server Compact database in my VS 2010 app. But when I run it, it acts like it executes fine (no errors), but a record is never inserted into my SQL Compact 3.5 database when I go to view the tabl...
