SQL Server 2005 Mobile: Problem With Connection To Database
Aug 3, 2006
Hi, everyone! I have a small problem.
It consists in:
1. I'm trying to connect to database on my Pocket PC within Visual Studio 2005 (C#)
Connection string looks like this:
SqlCeConnection1.ConnectionString = "data source = '\storage card\mobiluser.sdf'";
But when i'm deploying it to Pocket PC the error "An error message cannot be displayed because an optional resource assembly containing it cannot be found" appears.
2. When I'm doing te same on Pocket PC Emulator everything is normal.
Off course, I have the .sdf file on Pocket PC which is placed to Storage Card into root directory.
If anyone knows where I get a mistake, help me please!
Thanks for your help!

Hello Everyone,
I'm trying to connect to Desktop SQL Server 2000 from Windows mobile PC Emulator (VS 2005). I need a direct connection using connection string to SQL Server 2000 through local wireless network without IIS.
Bellow is the code that I use. After executing this code I get an error on line Conn.Open(). Error says SQL Server does not exist or access denied.
SQL is un and running, and I can log in using SA username from the desktop. Even if I chance IP for another SQL server in my connection string I still get the same error. There is no firewall of any kind running.
Dim connectionSTR As String = "Persist Security Info=False;Integrated Security=False;Server=192.168.0.202,1433;initial catalog=MyDB;user id=sa;password=;"
Dim Conn As SqlConnection
Conn = New SqlConnection(connectionSTR)
Conn.Open()
If Conn.State = ConnectionState.Open Then
MessageBox.Show("Open")
End If
About my environment: SQL Server 2000 is running on Desktop PC with Windows XP SP2. Application which I need to connect to SQL Server is in Visual Studio 2005. I execute the application in Windows Mobile PC Emulator and try to connect to SQL Server from emulator.
Your advice and help is very appreciated
Thank you
Ika

I have a working Pocket PC 2003 app that uses RDA to exchange data with SQL Server 2000. I'm attempting to port it to a Windows CE 5.0 device. (I'll be porting to Mobile 5 in the near future, but the gadget I have at the moment is CE).
I installed SQL Server 2005 Mobile Edition on the computer running IIS according to package directions, and used the wizard to set up a virtual directory with sscesa30.dll.
The directory I was previously using with sscesa20.dll is still there, and still works.
I set up the virtual directory to use basic authentication without SSL. (I know that's not advisable). I have confirmed that I can reach the URL using the username and password I supplied to the wizard.
When I try to pull data I get the following:
------------------- SQL CE Exception
Error Code: 80004005
Message : An error has occurred on the computer running IIS. Try restarting the IIS server.
Minor Err.: 28022
Source : Microsoft SQL Server 2005 Mobile Edition
I have tried restarting IIS without effect. Any clues?

Good day,
I am writing an application using VB.Net 2005 for the Windows CE 5.0 device and it is connecting to a SQL Server 2005 Mobile Edition Database.
The trouble I'm having is establishing a connection to a SQL Server Mobile database on the device.
Here is the code I am using:
Code Snippet
Public gConnectionString As String = "Data Source=Program FilesMobAppMobDB.sdf;Persist Security Info=False;"
Code Snippet
Imports System.Data.SqlServerCe
Public Class DBManager
Public Shared gSQLCEConnection As SqlCeConnection
Public Shared Function OpenDB() As Boolean
If gSQLCEConnection IsNot Nothing Then
Throw New InvalidOperationException("Connection already open.")
End If
gSQLCEConnection = New SqlCeConnection(gConnectionString)
Try
gSQLCEConnection.Open() 'Error occurs here
Return True
Catch ex As SqlCeException
MsgBox(ex.Message & vbCrLf & ex.HResult & vbCrLf & ex.NativeError & vbCrLf & ex.Source)
Return False
End Try
End Function
In the immediate window I recieve the following messages:
A first chance exception of type 'System.IO.FileNotFoundException' occurred in mscorlib.dll
A first chance exception of type 'System.IO.FileNotFoundException' occurred in mscorlib.dll
A first chance exception of type 'System.UnauthorizedAccessException' occurred in mscorlib.dll
A first chance exception of type 'System.UnauthorizedAccessException' occurred in mscorlib.dll
A first chance exception of type 'System.UnauthorizedAccessException' occurred in mscorlib.dll
A first chance exception of type 'System.IO.FileNotFoundException' occurred in mscorlib.dll
A first chance exception of type 'System.IO.FileNotFoundException' occurred in mscorlib.dll
A first chance exception of type 'System.UnauthorizedAccessException' occurred in mscorlib.dll
A first chance exception of type 'System.Data.SqlServerCe.SqlCeException' occurred in System.Data.SqlServerCe.dll
I believe that the first few lines are caused by the icons/pictures that I have included with my app, but the SqlCeException line occurs when the connection to the .SDF file is trying to be established.
Here is the exception output:
Message: "" (Blank)
HResult: -2147024882
NativeError: 0
Source: SQL Server 2005 Mobile Edition ADO.NET Data Provider
Programs under Remove Programs on the PDA are:

Microsoft SQL Server 2005 Compact...
Microsoft SQL Server 2005 Compact...
Microsoft SQL Server 2005 Compact...
Microsoft SQLCE 2.0
Microsoft SQLCE 2.0 Dev
Any ideas on what could be stopping this connection from being established? It was working before but all of a sudden just stopped. I have warm booted, cold booted, and rebuilt with no luck and also checked that SQL Query Analyzer is not running on the PDA and that the connection string is valid.
The call to OpenDB occurs in the form_load of the startup object.
Thanks in advance,

Dear ppl,
I am writing an application for a device (MDA Pro T-Mobile) having Windows Mobile 5.0 using
-MS .NET Compact Framework 2.0 SP-1
-SQL Mobile 2005.
-VS 2005 .NET
The application uses Merge Replication. The error occurs in the Synchronise() Method of the SqlCeReplication object.
"SQL Server Mobile encountered problems when opening the database."
repl.AddSubscription(AddOption.CreateDatabase);
repl.Synchronize();
I don't understand why I am having this error. It does create the database on AddSubscription() method but it is failing opening the database on Synchronise(). I have also tried uninstalling and then reinstalling all the SQL Mobile components in the following order.
-sqlce30.wce5.armv4i.cab
-sqlce30.repl.wce5.armv4i.cab
-sqlce30.dev.ENU.wce5.armv4i.cab
However, when i run this application on a device(Dell X50 AXIM) with Pocket PC 2003, it runs fine creating the database and sysnchronising it.
The target platform for the project is Windows Mobile 5.0 Pocket PC SDK.
Does any one have any clue what could be the problem ?
Regards
Nabeel

Hello,
I am developping a non-managed C++ application for PocketPC using a SQL Server mobile database.
The application is compiled for PocketPC 2003 and uses SQL Server Mobile v2. I use Visual Studio 2005. But I need to compile the application for Windows Mobile 5.0 devices. So I installed the WM5 SDK and had the WM5 into my project configuration.
The "ssceoledb.h" which I include incluses the "transact.h" file. But my problem is that this file is only provided with the PocketPC 2003 SDK and not in the WM5 SDK.
So I cannot use the WM5 configuration project with SQL Server. I also tried with the last SQL Server Mobile 2005 (ie v3.0) and the "ssceoledb30.h" also includes "transact.h".
Did I miss something to install ?
Do you know how I can resolve the problem ?
By advance, thank you for any answer.

Hi,
I was wondering if someone could help me as this is a bit of a puzzle.
I have created a database using a password, the create table scripts are executed successfully using the connection string however when I try and use the same connection string to insert some data into the database an error is produced, with the following message 'The specified password does not match the database password'.
I have opened the database using the SQL Server 2005 Management Studio and provide the password and I can access the database without a problem.
When the connection object is first instantiated all the Connection String property, the connStr variable and the modifiedConnStr are all correct (by this I mean that the data source and the password are present). However when the connection object is accessed again the Connection String property and the connStr variable are both set incorrectly (by this I mean that the password= section of the string is missing) however the modifiedConnStr is set correctly (by this I mean that the password= section is present in the string).
The connection object does not get set in between creating and accessing the connection object.
I have resorted to using no password, however I really need to be able to use a password.
Here is a copy of the connection string I am using (Copied directly from the quick watch window):
"Data Source = '\Program Files\Application\DataBase\MyDatabase.sdf'; password="Pa55word";"
I am sorry this a little long winded however I would like to provide as much information as possible. I hope someone can help me with this problem.
Thank you for reading.

Hi,
I'm trying to get my first replication going, and I have set up a database successfully, along with merge replication, however when I attempt to create the first subscriber, I get a permissions issue, regardless of what I do. In the SQLCESA30.LOG file, I get the following entries:

I posted the initial thread under the "Replication" forum, but am including this 'pointer' post here due to a lack of replies there, and the relevance of this thread to this forum. Please see http://forums.microsoft.com/MSDN/ShowPost.aspx?PostID=193693&SiteID=1 for more details.

When I try and connecto to SQL CE I always get an invalid operation exception. I"m afraid that I did not follow the proper install for Orcas Beta 2. I can't remember if I was supposed to uninstall SQL Mobile 2005 first or not.
All I know is when I try and use my SQL CE I can't connecto to a DB / sdf file ?
Any help would be appreciated I"m just starting to use SQL CE.

I'm seeking suggestions on how to go about encrypting a database connection string in the compact framework. It's something that I thought would be relatively straight forward as I've accomplished it without much difficulty in the full framework, but I'm stuggling to find a solution.
I've been trying to implement a solution using public/private key asymmetric encryption using the RSA provider. I've essentially been trying to encrypt the connection string once on my development machine so that I can include both the encrypted connection string value and public key in either code or an external file. I'd then keep the private key out of harms reach. The problem I've encountered in doing this is that that RSA provider seemingly only allows new "in session" keys to be generated and I can't figure out a way of importing a public key from a file or other similar means.
I found the following code which is meant to allow a key to be retrieved from a signed assembly or an SNK file, which I've converted to VB but haven't been able to get working:
http://www.topxml.com/-NET-XML-System-XML/re-2963_Get-RSA-Public-key-from-Assembly-or-SNK-File.aspx
After the code seems to successfully prepare the CspParameters from an SNK files, I get an unspecified error when executing ImportParameters on the RSA provider.
I'd imagine this to be a common requirement, but haven't been able to find much information specific to the compact framework on the web. Any guidance would be much appreciated.
Thanks,
Steve

I want to physically move my .SDF file to my desktop and then access this file from VS 2005 VB.NET. Ideally, I would want to access this .SDF file from MS Access 2003 but I undersand this is not possible.
Here are my VS 2005 VB.NET statements....
Dim ConnPPC As New System.Data.SqlClient.SqlConnection("Data Source = C:Documents and SettingsG014436My DocumentsSQL
MobileActMgr6CE.sdf")
Dim mySqlDataAdapter2 As New SqlDataAdapter("select * from T0002_AE_Activity_Entry", ConnPPC)
mySqlDataAdapter2.Fill(myDataSet2)
On executing the last statement(fill)...I get the following error.
function failed: An error has occurred while establishing a connection to the server. When connecting to SQL Server 2005, this failure may be caused by the fact that under the default settings SQL Server does not allow remote connections. (provider: SQL Network Interfaces, error: 26 - Error Locating Server/Instance Specified)
Does anyone have any suggestions?

I am migrating a pocket PC application from VS 2003 to VS 2005 and a few weeks ago I hit the following problem when replicating
A SQL Mobile DLL could not be loaded. Reinstall SQL Mobile. [ DLL Name=sqlceca30.dll]
Scanning forums for help I saw that other people had had this problem and one
http://www.eggheadcafe.com/aspnet_answers/NETFrameworkCompactFramework/Feb2006/post25814466.asp
suggested that this problem could be circumvented by getting the replication object early and then continuously using the same object for subsequent replications.
I did this and it works a lot better now but ever so often I get another error which is
Native Error 28559 SQL Mobile encountered problems when opening the database
My only option at this point is to stop and start the application which cures the problem.

I just got a shared hosting plan with godaddy (economy plan) ...
I wrote a simple application with a database. it works fine on my local PC.
I tried to upload my files to the server, but i couldn't get database file on godaddy's server. I did a little research and found out they dont allow uploading database files to their server nor they allow remote access either.
so I logged in to my account and found a database links and I created one (SQL Server)
Host Name
whsql-v44.prod.mesa4.secureserver.net
Database Name
DB_43434
Database Version
2000
Description
maindb
I then logged in to the database and created a new table .. but now I dont know how to make a connection between this database and my application on my pc.
I later found that I must modify my web.config file for the database to work. http://help.godaddy.com/article.php?article_id=689&topic_id=216&prog_id=GoDaddy&isc=
<connectionStrings><add name="Personal" connectionString="Server=whsql-v04.prod.mesa1.secureserver.net;Database=DB_675;User ID=user_id;Password=password;Trusted_Connection=False" providerName="System.Data.SqlClient" /><remove name="LocalSqlServer"/><add name="LocalSqlServer" connectionString="Server=whsql-v04.prod.mesa1.secureserver.net;Database=DB_675;User ID=user_id;Password=password;Trusted_Connection=False" providerName="System.Data.SqlClient" /></connectionStrings>
Now- I am new to web developing, but I do understand that this code is not enough to create the connection to the database. I researched alot but I cant get further.
What code/ settings/ steps do I need to do to get my gridview and other database items connect to the database on godaddy's server ?
any help would be greatly appreciated...

Hi,
Is there any way to measure bandwith usage during merge replication between sql server 2005 and sql server mobile 2005 running on a cradled wm5 mobile device.
Attaching the windows performance monitor to the network connection established over usb would work although I was wondering if there was something specific for this case integrated into Sql server 2005 / sql server mobile 2005 / Sql server management studio / third party tools that i could use ?
thnx,

Hi,
I have a central database server that is runnning on SQL 2005 standard edition and Windows server 2003 standard as OS.
I realise that I can use SQL statements to encrypt and decrypt the data inside the standard SQL.
However, how do I read and write the data via an web application coded in C#.net and is also running on the same machine?
Another issue is, I need to replicate some of the data in this SQL standard over to a SQL mobile running on a mobile device running on Windows CE 5.0.
The mobile device also needs to read and write data to the encrypted data via a C#.net application.
Question is, with all these requirements to be met, can I use AES? I know that AES is not available on Windows XP and Windows Server 2000 and I cant find AES in the .net compact framework.
how do i go about ensuring security? how do I ensure that the symmetric key is the same both on the SQL standard and SQL mobile?
thank you.

I'm attempting to use RDA to synchronize a pocket pc emulator with SQL Server 2005 database by following tutorial http://msdn2.microsoft.com/en-us/library/aa454892.aspx, which uses AdvWorksMobile database that comes with SQL Server 2005.
When get to testing of "To test application features " ( step 4 of the merge replication setup lab ), I am receiving SQLCe Exception errors.
ORIGINALLY, I was able to deploy an application and view the local database on the emulator, but once I clicked "InitSinc" button, I received an error.
"Failure to connect to SQL Server with provided connection information. SQL Server does not" exist, access is denied because the SQL user is not a valid user on the SQL Server, or the password is incorrect.
Found this error listed in Server Agent Errors log http://technet.microsoft.com/en-us/library/ms172357.aspx, but it wasn't very helpful since it doesn't provide any suggestions on fixing the problems.
I am brand new to SQL CE Server , mobile programming and .NET framework in general so please bare with me
All the connections / security settings, etc that were set up were taken from a tutorial so I am not sure what SQLCeServer is complaining about. Reading up on the error on the web didn't help, it all pointed to making sure that the snapshot folder had correct permissions set up. I verified that MACHINENAMEUISR_MACHINENAME guest user had Read rights to the database so I don't think that piece is the problem. Otherwise ,Merge publication has been setup in Microsoft SQL Server Management Studio by following the tutorial.
I am trying to run this sync on my home pc so there should be no issues with any user permissions
I have IIS installed
I did NOT have SQL Server Agent running in management studio at this time
I am trying to run this tutorial on an XP machine, which is my regular home PC so I dont think there are any special networking settings to consider
I am able to hit http://localhost/AdvWorksMobile/sqlcesa30.dll from my pc OK, but when I try to hit it from a cradled emulator ( after replacing "localhost" with "MACHINE_NAME" ), Internet Explorer on the emulator gives me a "Cannot Connect With Current Settings" error message. This part wasn't part of tutorial but decided so not sure if I am supposed to be able to hit it from my emulator..so I am not sure if the fact that I can't hit it is related to the problem.
AFTER STARTING SQL SERVER AGENTin Microsoft SQL Server Management Studio, I killed the application, and after relaunching it, it hits "The Specified table does not exist [Vendor]" error. This time it doesn't even launch first - that is I dont even get to pressing "InitSinc" button. Debugger is showing that this error is hit on the following line in AdvWorksMobile.AddWorksDataSetTableAdapters
int returnValue = this.Adapter.Fill(dataTable);
I am not sure why the errors changed on me after starting SQL Server Agent.
What can I do to fix this connection problem?
Thank you so much for your help!

Hi, all. I am using VS.NET 2005 and SQL Server 2005 Express. I tried to use the following code to connect to a database named "AMSPROD" that I attached to SQL Server 2005 Express:
dbConn = new OleDbConnection(Data Source=.SQLEXPRESS;AttachDbFilename="C:Program FilesMicrosoft SQL ServerMSSQL.1MSSQLDataAMSPROD_Data.MDF";Integrated Security=True;Connect Timeout=30;User Instance=True);
dbConn.Open();
I got an error asking for provider with the above connection string, then I changed the conncection string to be like follows:
Data Source=.SQLEXPRESS;AttachDbFilename="C:Program FilesMicrosoft SQL ServerMSSQL.1MSSQLDataAMSPROD_Data.MDF";Provider=SQLNCLI;Integrated Security=True;Connect Timeout=30;User Instance=True
I got error: No error message available, result code: DB_E_ERRORSOCCURRED(0x80040E21)
Then I changed the Provider to be like: Provider=SQLOLEDB, now I am getting the following error:
Message: "Invalid authorization specification
Invalid connection string attribute"
Source: "Microsoft SQL Native Client"
StackTrace: " at System.Data.OleDb.OleDbConnectionInternal..ctor(OleDbConnectionString constr, OleDbConnection connection)

Strange thing is, when I use the Connect To Database under Tool menu of VS.NET 2005, I could make the connection to this database. Then I copied this connection string to the code, the connection couln't be made. I feel very confused.
I am wondering if I need to add ASP.NET user to SQLExpress. But I don't know how to do it?
Can anyone please help me out! Many thanks!

I have a SQL Server 2005 database (called BDHSE) in a PC which i call PC1. I have a second PC (PC2) and both are within a network (a WLAN).
What i want is to have access to BDHSE from an application in VB6 (APP1) running in PC2. All the INSERT, DELETE, UPDATE records process is done through APP1.
APP1 ia currently running in PC1 and is to be installed on PC2.
I have these questions:
1. What do i need to install in PC2 since all the INSERT, DELETE, and UPDATE is done using APP1? I guess i only have to install the Microsoft SQL Native Client (with all the prerequisites of course) but i am not sure.
2. In the APP1 made in VB6, do i have to change the connectionstring since i am accesing the database which physically is at PC1 and the APP1 will be used in PC2?
3. Any advice you can give me on doing this will be well received.
Thanks in advance,

My platform is using a PDA with winCE 4.2 and SQL server CE. The Host program is using dbf files on desktop side.
I got a problem of how to sync / read the sql CE data from a windows application.
so, i wanna ask,
1. any method to access the data from winCE data by windows application? or can i convert the sdf file to windows readable files? or any others?
2. Can i use a MDB to sync with SQL server CE?
can i synchronize the mobile device which has a SQL Server CE database with the Access database on the desktop?
last question,
3. is that windows CE .net 4.2 not support pocket access (cdb) anymore?
please help me out

I am setting up a web server and I'm having some issues with database connections. I am running Windows Server 2k3 and SQL Server 2005. The error I get is when I attempt to connect to the database, it's the following:
Cannot open database "dbReseacher" requested by the login. The login failed. Login failed for user 'userRes'.
The following is my connection string:
<add name="RESEARCHER" connectionString="Data Source={Sql Server}; Server=THRALL2; Database=dbReseacher; Uid=userRes; Pwd=password;"/>
In SQL Server Management Studio, the user userRes is listed under Security -> Logins, but it is not listed under Database -> dbResearcher -> Security -> Users. Originally it was listed under both and this didn't solve the problem.
Please let me know if you any ideas or questions that I can answer. Thanks a lot.
