Any body has idea what is the cause and fix? Tuesday, June 13, 2006 7:48 PM Reply | Quote Answers 7 Sign in to vote Weird errors like this are often the result of multi-threading access to objects that are not threadsafe. Even if your code is not explicitly creating multiple threads, you have to be careful of
Internal .net Framework Data Provider Error 1025
situations where multiple threads may be used internally. I noticed that your call stack shows that the SqlDataReader.Close call is coming from your Finalize method (it's directly coming from Dispose, but Dispose is being called by Finalize). It is not safe to call any managed objects in Finalize, because it is called non-deterministically by the garbage collector on a separate thread. The SqlDataReader.Close documentation explicitly calls this out: SqlDataReader.Close Method http://msdn2.microsoft.com/en-us/library/system.data.sqlclient.sqldatareader.close.aspx Caution Do not call Close or Dispose on a Connection, a DataReader, or any other managed object in the Finalize method of your class. In a finalizer, you should only release unmanaged resources that your class owns directly. If your class does not own any unmanaged resources, do not include a Finalize method in your class definition. For more information, see Garbage Collection. You should explicitly close the SqlDataReader when you are done using it, before finalization. If you do that and are still running into problems, post back again with a new error message and call stack (if they have changed).Thanks,Sarah Thursday, June 15, 2006 12:12 AM Reply | Quote All replies 0 Sign in to vote Could you please give a complete call stack

Where is source of error? There is a class library DLL created by another person. I used C# (VS 2005 Professional Edition) and SQL Server 2005 Express Edition and also used Visual SourceSafe 6.0.In this class,There is a constructor and net framework destructor in the destructor it calls the CloseConnection() method where the error occurs.Code:private void CloseConnection() {if (m_Connection != null) {try {// Check if connection is already closed, if not, then close itif (m_Connection.State != ConnectionState.Closed)m_Connection.Close(); <<---Error Occurs here// Dispose the connection object and set it to null to release resources used by the objectm_Connection.Dispose();m_Connection = null;}catch {throw;}}}***RESOLVED*** I created new class net framework data to do same function without using destructor to close connection. I am puzzled why this class works with version 1.1 and SQL 2000...Confuse?:confused:denpsia -----------------------------------------------------------------------------------------Please make sure if problem in your post is solved, add Resolved icon and/or add "[Resolved]" in your title on first post.

I'm not 100% sure but I think there might be a problem with trying to close a connection that has a ConnectionStatus other then Open.

Internal .Net Framework Data Provider error 1 P: n/a Andrew Win2k3 IIS6 ..NET 2.0 In my ASP.NET 2.0 app I create an open an SQL connection in the page's constructor and call objSQL.Dispose() in the destructor. The SQLConnection object is a class member of the page. Here's the destructor code: /// Destructor ~Officer() { if( m_objConn != null ) m_objConn.Dispose(); } /// End Destructor When running this particular page through some testing I get the following exception in the destructor at the "m_objConn.Dispose();" line: System.InvalidOperationException was unhandled Message="Internal .Net Framework Data Provider error 1." Source="System.Data" StackTrace: at System.Data.ProviderBase.DbConnectionInternal.PreP ush(Object expectedOwner) at System.Data.ProviderBase.DbConnectionPool.PutObjec t(DbConnectionInternal obj, Object owningObject) at System.Data.ProviderBase.DbConnectionInternal.Clos eConnection(DbConnection owningObject, DbConnectionFactory connectionFactory) at System.Data.SqlClient.SqlConnection.Close() at System.Data.SqlClient.SqlConnection.Dispose(Boolea n disposing) at System.ComponentModel.Component.Dispose() at Officer.Finalize() in c:\sys\projects\AddOfficer.aspx.cs:line 46 When I stop debugging VS2k5 pops up the JIT debugging dialog stating an unhandled exception occurred in w3wp.exe. 1) Is this a bug? 2) Do I need a try/catch in a destructor? Is it good programming practice? 3) Why is this happening? 4) What is the meaning of life? Any help is appreciated.

Open and close the connection each time you need to. Let Connection Pooling work for you. Jeff "Andrew"
