It runs fine for a little while (19 rows...19 full loop cycles) then I get a runtime exception being thrown by connection.Open() I have the entire loop inside a try catch block in order to catch the exception and produce the message then http://stackoverflow.com/questions/19323236/system-data-oledb-oledbexception0x80004005-unspecified-error 2 blank lines then the stack trace. I have tried to read this and figure out what to do but I am a bit of a Novice when it comes to DB connections. I have looked elsewhere but do not seem to find a question that quite fits my situation. FYI: C# 4.0 Windows Form Application, Access DB I am hoping to find some suggestions on where to begin looking. I am positive that my connection is closed when this error is thrown due to the validation i implemented as shown here: internal IDbConnection GetConnection() { try { var connection = _assemblyProvider.Factory.CreateConnection(); connection.ConnectionString = _connectionString; _connectionState = connection.State.ToString(); if (_connectionState == "Open") GetConnection(); else { connection.Open(); } return connection; } catch (Exception exept) { throw new Exception(exept.ToString() + "\n\n" + exept.StackTrace.ToString()); } } This method is being called from here: public DataTable ExecuteDataTable(string commandText, string tableName, DbParameterCollection paramCollection, CommandType commandType) { DataTable dtReturn; IDbConnection connection = null; try { connection = _connectionManager.GetConnection(); dtReturn = _dbAdapterManager.GetDataTable(commandText, paramCollection, connection, tableName, commandType); } finally { if (connection != null) { connection.Close(); connection.Dispose(); } } return dtReturn; } public DataTable ExecuteDataTable(string commandText, string tableName, CommandType commandType) { return ExecuteDataTable(commandText, tableName, new DbParameterCollection(), com

I've moved oledbexception was caught it from database forum to here in hopes that someone can help. If anyone can help me, please do so. Here's what i posted: I have been given a task to normalize a table. To that end, I have split up the original table into smaller, normalized ones. Part of the process requires that I rename all the PrimaryKeys and their associated Foreign keys. Im trying to create a program that will go through all the tables, and renaming the pk and fk. each table has about 8000 records.
