Native Exception at at SqlCeCommand.set_CommandText(String value)

Posted By:      Posted Date: April 10, 2011    Points: 0   Category :

I am having random native exception and all of those exceptions have this method common i.e  at SqlCeCommand.set_CommandText(String value). I am using .NETCE 3.5, SQLCE 3.5 SP2, i.e. System.Data.SqlServerCe.dll version 3.5.8080.0 and I also verified the version of Native dlls and it matches with managed dll.

Can anyone know why I am getting this native exception?

Here is the exception stack

ExceptionCode: 0x80000002

ExceptionAddress: 0x00e8c440

Faulting module: sqlceqp35.dll

Offset: 0x000bc440

Error: A native exception has occurred in my_file.exe

Hello everyone,   This error is occurring with me when I am working with SSCE in my pocket PC. Can anyone tell me why?   Thanks!

Native exception 0xc0000005 when using SQLCE 3.0/3.1 and .NET CF 2.0?!

Greetings, I have written a very basic C# console test app to check the performance and reliability of SQLCE on Windows CE 5.0 (source code below). Running this on different Windows CE 5.0 devices, I always get a 0xc0000005 native exception error when reaching 25592 inserts. It doesn't matter whether the database is empty or not when the test is run, it always fails at that exact number of inserts. Given that I would expect a managed application not to be able to generate native exceptions anyway, and can't really see any reason why it would in this case, I'm at a bit of a loss as to what's going wrong... Any ideas? Using: VS2005 w/ SP1 Windows CE 5.0 (on custom SH4 platform and HTC WM5 smartphone) .NET CF 2.0 w/ SP1 and post SP1 patch SQLCE 3.0.3600.0 TIA PS. The same code (with some SQLCE 3.0 specific bits removed - version and result set for checking table existence) works perfectly under .NET CF 1.0 and SQLCE 2.0). Source code: using System.Data; using System.Data.SqlServerCe; namespace TestDB {     class Program     {         static void Main(string[] args)         {             SqlCeConnection sqlConnection = new SqlCeConnection();             SqlCeCommand sqlCommand = sqlConnection.CreateCommand();             SqlCeResultSet sqlResult;             string strDatabase = "\\TestDB.sdf";             string strTable = "TestTable";        

Exception when initializing private key from xml string (RSACryptoServiceProvider using FromXmlStrin

Hi, I'm trying to create a private key using the following code segment   System.Security.Cryptography.AsymmetricAlgorithm key = new System.Security.Cryptography.RSACryptoServiceProvider();string privateKeyXml = File.ReadAllText(fullPathPrivateKey);key.FromXmlString(privateKeyXml);   It does work with .NET Framework 3.5 SP1 on Windows XP, but when I try to run it on .NET Framework 4.0 on Windows 7 I get the following exception ((System.Security.Cryptography.RSACryptoServiceProvider)(key)).CspKeyContainerInfo.Exportable' threw an exception of type 'System.Security.Cryptography.CryptographicException', with message "Key does not exist". Full stack trace is shown below: System.Security.Cryptography.CryptographicException: Key does not exist. at System.Security.Cryptography.CryptographicException.ThrowCryptographicException(Int32 hr) at System.Security.Cryptography.Utils._GetProviderParameter(SafeProvHandle hProv, Int32 keyNumber, UInt32 paramID) at System.Security.Cryptography.CspKeyContainerInfo.get_Exportable() Does anyone have a clue to why this doesn't work on .NET 4.0? Regards, Simon

Native Exception in GetKeyInfo()

We developed a product on Win CE 5 using Visual Studio 2005. I am evaluating an upgrade to Visual Studio 2008 because we believe the SQL Server CE 3.5 database format is better supported.

We installed updates in platform builder to get SQL Server CE 3.5 and we rebuilt the platform. I have installed Visual Studio 2008 with SP1 for both .net and SQL Server CE.

I tried making an entirely new project with a fresh DB for testing, so that everything will agree and there won't be any strange faults lingering from settings in any old project. All the Properties sheets seems to indicate that my database is a 3.5 database. The project builds and deploys with no problems, but after the connection is open, any attempt to fill a table from the database results in this exception:

Exception Code: 0x80000002
Exception Address: 0x03194008
Faulting Module: sqlceme35.dll
at NativeMethods.GetKeyInfo( IntPtr pTx, String pwszBaseTable, IntPtr prgDbKeyInfo, Int32 cDbKeyInfo, IntPtr pError )
at SqlCeDataReader.FillMetaData( SqlCeCommand command )
at SqlCeCommand.InitializeDataReader( SqlCeDataReader reader, Int32 resultType )

The fault is happening in MS code that I cannot step into...anyone recognize this problem?

SQL Server Native Client Connection String



Currently we are using many config files with SQLNCLI. Is there a way if we would like to use SQLNCLI10 features without changing so many files?




Every self-respected programmer should include exception handling techniques. Sometimes your application will generate an error. Regardless of who was responsible for this error, the programmer or the user, it is up to the first to include the necessary exception handling techniques to keep his/her program from crashing. The .Net environment provides useful techniques for avoiding disastrous errors such as try-catch statements and user-defined exceptions.

Global Exception Handling with ASP.NET

After your global exception handler has done its work, you'll want to redirect the users of your website to a friendly page that tells them that something has gone wrong, and then provide them with customer support information as well as a link back to your web application's home page.

SQL Server 2005 Try and Catch Exception Handling

I'm pretty excited to see that there is some real error handling for T-SQL code in SQL Server 2005. It's pretty painful to have your wonderfully architected .NET solution tainted by less-than-VBScript error handling for stored procedures in the database. The big difference being the addition of TRY..CATCH blocks. Let's take a look:

SQL Connection String

We can learn or know how can we connect the database from our .net. This will help for freshers or .NET beginners!

Built-in Functions - String Functions

String functions let you extract various portions of character strings, change the case of strings, concatenate and reverse strings and perform many other types of manipulations. All built-in string functions are deterministic with the exception of CHARINDEX and PATINDEX

abstract away the source of the connection string using a class with a static property.

ASP.NET provides a configuration system we can use to keep our applications flexible at runtime. In this article we will examine some tips and best practices for using the configuration system for the best results.

The element of a web.config file is a place to store connection strings, server names, file paths, and other miscellaneous settings needed by an application to perform work. The items inside appSettings are items that need to be configurable depending upon the environment, for instance, any database connection strings will change as you move your application from a testing and staging server into production.

Let's abstract away the source of the connection string using a class with a static property.

connection string question from a newbie


when publishing  in the webmatrix dialogue it asks for "destination connection string" for my "database.mdf"

I was not sure what it was so I pasted this from my web.config file :

Data Source=.\SQLEXPRESS;AttachDbFilename=|DataDirectory|\database.mdf;Integrated Security=True;User Instance=True

it all published ok, but wont run, so I guess it has somthing to do with this connection string or some kind of configuration issue.

My question is this, What should go in the field for "Destination connection string"
