Can't P/Invoke Sqlceme35.dll With Headless Compact Framework
May 19, 2008
I am aware of the many posts that have addressed this issue in the past - I resolved this issue many months ago when it first happened to me. However, I have recently created a headless version of my Windows CE 6.0 based project that uses the Headless versions of the Compact Framework and this problem has suddenly re-surfaced. As in my UI equipped versions, the SQL CE cab files are copied to the device and have been installed. I have also tried copying the sqlceme35.dll to the application folder. The only real difference I can see is that the device is using the headless version so I suspect that there may be some incompatibility.
Has anyone successfully deployed a SCQL CE aplication to a headless device and if so were there any special steps that had to be taken to make it work?
Thanks

you can, with a dataset do something like myDataSet.WriteXml(m_XmlFile, XmlWriteMode.IgnoreSchema) and get XML for a record....
is it possible to do something like that with SQLserverCeresultset?
i know i could probably loop thru the columns and create the xml manually... but using somethinglike writexml will give better performance?
right now im not using anything from the XML class... from my previous exp with using XML classes on the Compact framework gives slow performance...

I have two instances of SQL Server on the same PC:
Default instance: SQL Server 2000
Named instance with name €śMS2005€?: SQL Server 2005.
Also I have another SQL Server 2005 on another PC.
I created a .NET 2.0 Compact Framework application that connects to the database and executes simple query. This application can connect to any instance of the SQL Server when it is executed on the PC (not on the server). But the problem is that when I try to execute the application from the windows CE 5.0 device, the application can only connect to the default instance (SQL 2000 and 2005) and can not connect to the named instance (Name: MS2005).
Is it some kind of limitation of the SqlClient library for the compact framework?
Below are the code and connection strings:
string connectionString = €śServer=1.1.1.1;Database=DB1;Uid=sa;Pwd=€?
string connectionString = €śServer=1.1.1.1\MS2005;Database=DB1;Uid=sa;Pwd=€?
using (SqlConnection connection = new SqlConnection(connectionString))
{
connection.Open(); //This is the point where exception is generated
using (SqlCommand command = connection.CreateCommand())
{
command.CommandText = "select count(*) from users";
object result = command.ExecuteScalar();
Console.WriteLine("Result: [{0}]", result);
}
connection.Close();
}
Thank you for your time and advice.

How can I tell if the System.Data.SqlServerCe assembly I am referencing is meant for Desktop use as opposed to Compact development? We are using NUnit as our testing framework and I get the following error when I attempt to execute nunit-console on my test fixture referencing SqlServerCe:
System.IO.FileLoadException : Could not load file or assembly 'System.Data.SqlServerCe, Version=9.0.242.0, Culture=neutral, PublicKeyToken=89845dcd8080cc91' or one of its dependencies. The located assembly's manifest definition does not match the assembly reference. (Exception from HRESULT: 0x80131040) ---->
System.IO.FileLoadException : Could not load file or assembly 'System.Data.SqlServerCe, Version=3.0.3600.0, Culture=neutral, PublicKeyToken=3be235df1c8d2ad3, Retargetable=Yes' or one of its dependencies. The located assembly's manifest definition does not match the assembly reference. (Exception from HRESULT: 0x80131040)
The unit tests run fine from inside of Visual Studio using the Resharper Unit Test Runner...

Hi all,
I am trying to access my SQL Server database through SqlCeConnection:
cecon = new SqlCeConnection("Data Source=D:\D_Drive\csharppract\nddbpda\nddbpda\nddbpdadatabase.sdf");
cecon.Open();
I am getting the following error:
System.Data.SqlServerCe.SqlCeException was unhandled

When I tried to get the path from which the database file is being accepted, I got a different path:
string path;
path = System.IO.Path.GetDirectoryName(
System.Reflection.Assembly.GetExecutingAssembly().GetName().CodeBase);
MessageBox.Show(path);
This code gives me this path:
Program Filesddbpda
Then I changed the path in my connection string to this:
cecon = new SqlCeConnection("Data Source=\Program Files\nddbpda\nddbpdadatabase.sdf");
cecon.Open();
When I ran my application it worked (virtually), but the database is not getting updated (for obvious reasons).
What should I do now to correct this?
Thanks in advance.

We are developing Microsoft SQL Server CE 2.0 Merge Replication Using .NET Compact Framework. There is need of sinhronizations between SQL 2005 Mobile Edition witch resides on Barcode terminal (Windows CE) and SQL 2005 Developer Edition (on Windows XP). Everything is done by the book. There is few lines of code that we are using:
public bool Replicate()
{ bool ret = true;
SqlCeReplication repl = null;
try {
// Instantiate and configure
SqlCeReplication object repl = new SqlCeReplication();
string dbFile = ........
repl.InternetUrl = this.InternetUrl;
repl.InternetLogin = this.InternetLogin;
repl.InternetPassword = this.InternetPassword;
repl.Publisher = this.Publisher;
repl.PublisherDatabase = this.PublisherDatabase;
repl.PublisherLogin = this.PublisherLogin;
repl.PublisherPassword = this.PublisherPassword;
repl.Publication = this.Publication;
repl.Subscriber = this.Subscriber;
repl.SubscriberConnectionString ="Data Source=" +dbFile;
if (!System.IO.File.Exists(dbFile))
{ repl.AddSubscription(AddOption.CreateDatabase);
}
repl.Synchronize();
}
IIS is configured, but in log on the server we've got this error:

Hi! I tried to save some image data, but it get truncated at 8000 (the table column is defined as Image). I then wrote a converter to try ntext-datatype instead, but it gets truncated at 4000.
Error message:
System.Data.SqlServerCe: @3 : String truncation: max=4000, len=4168
The code uses only ADO entity framework for database access. Is there a way to store binary data larger than 8000 bytes? I am running SQL Compact 3.5 sp 1 BETA.

Hello
I have recently downloaded Orcas beta VS product and had no previous version of VS before. The install went clean and I have been able to generate Window apps and web apps with very little issues; however, I have one issue with running a web app using the "view in browser" option for checking an aspx page for validity. If I use the default Northwind database provided and generate an aspx form using the "DataSet" toolbox widget, the tool prompts for the datasource etc. required to generate the required code. I can select the Northwind database and select the desired columns from one of the tables. Once completed, I build the project (clean build) and then select the "view in browser" option to verify the results. The result is an error page indicating a server error ->
Failed to find or load the registered .Net Framework Data Provider.
Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.
Exception Details: System.Configuration.ConfigurationErrorsException: Failed to find or load the registered .Net Framework Data Provider.
I created on odbc connection to an iSeries(as400) box and was successfull in displaying the table on the webpage! I looked into the web.config file and it appears that all the required XML data is present. Any help would be appreciated as I am fairly green when it comes the .NET world.
Thanks

As you all know, in Framework 2.0 on the desktop platform you have the convenient "abstract" Db* classes that can be used to write more generic code. For instance System.Data.SqlClient.SqlConnection inherits from System.Data.Common.DbConnection, and so forth. Now the docs clearly say that this applies to the corresponding classes in the Compact Framework. And i have seen this implied by other web searchs I've done. However this does not seem to be the case -- or, I'm missing something somewhere.
The following simple code on the desktop platform compiles OK:
using System.Data;
using System.Data.Common;
using System.Data.SqlClient;
DbConnection conn = new SqlConnection();
However it doesn't compile in a compact framework project: "Cannot implicitly convert type 'System.Data.SqlClient.SqlConnection' to 'System.Data.Common.DbConnection'".
Reflector also indicates that the Compact Framework class doesn't inherit from DbConnection.
OK, so am I missing something here, or what was the reason that Microsoft did it differently??

I watched and followed the Intro to VB 2008 Express, but in the final part of the video, when you add a database, i did everything as the video says, still i get:
An error occurred creating the form. See Exception.InnerException for details. The error is: Unable to load DLL 'sqlceme35.dll': The specified module could not be found. (Exception from HRESULT: 0x8007007E)
Ive tried the fix stated in another forum, the one about changing the "Target CPU" but the option doesn appear, what does appear its the "Platfrom" dropdown list, but its fixed to "Any CPU" and dont have any more options.
Ive also downloaded Microsoft SQL Server Compact 3.5 ENU and "re-installed" and selected repair, followed the steps, rebooted and still nothing.
The problem persists, any ideas, please?

Team:
How to invoke a stored procedure "out of process", meaning i want to add it to a queue.
Reason: we have a proc that is fired real-time each time an order comes into the system and it take a few seconds and when there is plenty of order activity in the system, the process times out. I would like to essentially add this to a queue and move on and some other process will process from the queue. Is CLR call the way to do? I know that the easiest way can be to add to a table and process from the table every 5 mins or something like that. Thoughts?
Thx

Hi!
I have developed DTS package for various tasks and scheduled to run some time. I have included SQL Mail task to notify me for each process when it fails. The questions is, When I open the package and execute from the menu, it works and it notifies me through SQL Mail task when it fails but when DTS package invokes at scheduled time and it got failed but it did not notify me that process in between has failed. It seems like SQL Mail task does not work when i schedule the package. Is there any one did come across this situation? or is there any way to resolve this issue? Any help would be appreciated!
Thanks,

I've got an application uses a WPF GUI, is built in VS2008 final, targets .Net Framework 3.5, and uses a Sql Ce 3.5 database for local storage. After a specific WPF window is rebound the application hangs. Hitting pause on the debugger reveals the offending method is a call to SqlCeConnection.Dispose(). Via Reflector I can see this method calls SqlCeConnection+ObjectLifeTimeTracker.Close() which in turn calls GC.WaitForPendingFinalizers(). Within WPF there are some objects (specifically TextBox) which need to have their resources freed on the main application thread. The finalizer thread is waiting on the main application thread, which is in turn waiting on the finalizer thread, resulting in a deadlock.
You can see some additional discussion of the topic including our temporary resolution in this thread.
My question is why is there a call to GC.WaitForPendingFinalizers() buried within the SqlCeConnection.Dispose() call tree?

Dear all,
I'm trying to create a BLL for an objectdatasource to used for a sorted DataGrid. I am trying to learn about how to use LINQ and I'm sure this is a simple question.
var query = (from p in db.MP3Collections select p).OrderBy(?????????);
Now I want to invoke the following method List<MP3Collection> GetAllMP3s(string sortColumns), which can contain a string name for the field in MP3Collection that is to be sorted (and optionally the "desc" tag).
Now I'm resorting tocoding the query on a case by case basis, which is very tiresome (see the partial code below). This works fine, but is very long and tedious coding. I'm not sure how to go about neatening the code, though am sure it involves the ?????? space above.
Any ideas?
public static List<MP3Collection> GetAllMP3s(string sortColumns)
{System.Diagnostics.Debug.WriteLine("Pure sort expression: " + sortColumns);
bool descending = false;if (sortColumns.ToLowerInvariant().EndsWith(" desc"))
{
sortColumns = sortColumns.Substring(0, sortColumns.Length - 5);descending = true;
}string[] columnNames = sortColumns.Split(',');
MP3DataClassesDataContext db = new MP3DataClassesDataContext();
List<MP3Collection> query = (from p in db.MP3Collections select p).OrderByDescending(p => p.fileName).ToList<MP3Collection>();foreach (string columnName in columnNames)
{switch (columnName.Trim().ToLowerInvariant())
{case "filename":if (descending)
{
query = (from p in db.MP3Collections select p).OrderByDescending(p => p.fileName).ToList<MP3Collection>();System.Diagnostics.Debug.WriteLine("Sorting filename descending");
}
else
{query = (from p in db.MP3Collections select p).OrderBy(p => p.fileName).ToList<MP3Collection>();System.Diagnostics.Debug.WriteLine("Sorting filename ascending");
}
break;case "filepath":if (descending)
{
query = (from p in db.MP3Collections select p).OrderByDescending(p => p.filePath).ToList<MP3Collection>();System.Diagnostics.Debug.WriteLine("Sorting filepath descending");
}
else
{query = (from p in db.MP3Collections select p).OrderBy(p => p.filePath).ToList<MP3Collection>();System.Diagnostics.Debug.WriteLine("Sorting filepath ascending");
}
break;
//OTHER CASES HEREdefault:
query = (from p in db.MP3Collections select p).OrderBy(p => p.filePath).ToList<MP3Collection>();
//throw new ArgumentException("SortColumns contains an invalid column name.");break;
}
}
//var query = (from p in db.MP3Collections select p).OrderBy(p=>p.fileName).ToList<MP3Collection>();return query;

Until now we worked with SQL Server 7.0, now we're migrating to SQL Server 2005.
With SQL Server 7.0 we had an MS Access application (located on a file server) used by several users, from which's form a batchfile (located on the same server) can be started. The Batchfile deletes an existing TXT-file called import_result.txt, then invokes a DTS-Package (located on a SQL Database server) which imports data to the Access-DB and creates a new file with the result of the DTS-execution (again called import_result.txt). Like that the user gets some information about success (or failure) of the data import.
How could this be implemented with SQL Server 2005 without having to install (and to licencse) SQL Express Engine on the clients? I found some threads about how to invoke an SQL Agent Job from the client to execute the SSIS-Package on the server, but I think that's not exactly what we need. Besides I'm not quite sure how exactly the SQL Agent Job could be invoked from Access.
Do you have any proposals?
