Connection Path OK On Device, Not On Desktop
Oct 3, 2007
This code...
string Path = System.IO.Path.GetDirectoryName(System.Reflection.Assembly.GetExecutingAssembly().GetName().CodeBase);
// Create the connection fConnection = new SqlCeConnection("Data Source ="" + Path + "\TreeNotes.sdf" ;Password ="abcd1234";");
fConnection.Open();
...works on my device, but on my computer it gives SqlCeException with message:
The database file cannot be found. Check the path to the database. [ File name = Program FilesTreeNotesTreeNotes.sdf ]
I've tried all sorts of things, but the computer just can't find the database. I've even tried putting a copy of the database into...
C:Program FilesTreeNotesTreeNotes.sdf...hoping that the computer will find it there.
What am I missing?

Basically I've been using Visual Studio 2005 for a few weeks now moving a Pocket PC project from 2003 to 2005. When I hit the Start Debugging Button every time until today the project would rebuild and deploy to my pocket PC allowing me to debug etc but now I get
The remote connection to the device has been lost.
Please verify the device conection and restart debugging.
I used to get this problem in VS2003 sometimes and just like the numerous posts on different sites that I've looked at the problem eventually goes away and I'm none the wiser. One guy said that he found that if he went to bed the problem was resolved when he came back!
My PDA running Windows 2003 2nd Edition is directly connected to my PC via a USB port. I've rebooted my PC and done a soft reset on the PDA but it didn't help. I'm using ActiveSync 4.1.
Does anyone know how to resolve this problem?

I want to create an application that will have support two platforms, Window's desktop and Windows Mobile 5/6. The application will need to have the data synchronized when the device is put in the cradle via ActiveSync on WinXP or Sync Center on Vista.
I want to use the new SQL Compact Edition to do this. The problem I'm having is how do I sync the data? I know about RDA and Merge Replication, but for a generally distributed application to customers via the internet, how do I make this work seamlessly without a complicated setup? This application will be sold to thousands of users without technical knowhow of how to use advanced synchronization configurations.
I have to assume other developers must be interested in a scenario like this, but I have yet to see a good solution in my searches on the web or Microsoft's site.
I don't want to use Access on the desktop. I also don't want to use RAPI to transfer files as there are security issues with newer devices.
I'm coming close to scoping out a 3rd party database or home-grown solution, but this would not be optimal.

I want to create an application for home users which runs on their mobile device (smartphone) and their desktop PC and keeps the data synchronized between them. On their desktop I want to run either SSCE or SSExpress. There are so many options in the SSCE literature, which options should I use? How do I synchronize the data?
The literature has so many options I don't know where to start.

Hi,
I am trying to write a desktop application using C# and .NET that can edit an SQL Server Mobile database stored on a device. The problem is no matter how I specify the data source, I get an error the path was not found. Heres the bit of the code:
string strConn = "Data Source=" + "Mobile Device\My Documents\Nutricom.sdf";
SqlCeConnection connDB = new SqlCeConnection(strConn);
connDB.Open();
And the error i get is..
The path is not valid. Check the directory for the database. [ Path = Mobile DeviceMy DocumentsNutricom.sdf ]
Everytime it thorws an error saying the path is invalid and to check the locaiton of the database. Ive tried it without the "Mobile Device" bit of the string and still nothing. The database is definately in this location.
Any help? It's driving me insane.

I'm trying to set a backup job to back up my databases to a server other than the server where Sql server is installed. The only options I can see are the local drives on my sql server when I try to set a location or backup device. If I want my backups to go to another server , How do I do that. Currently I'm trying to use a UNC path like \ServerNameBackups. When I try to use a UNC path I get an invalid directory error.
I'm fairly new to SQL Server as you can tell!
Can anyone help me? (I'm using sql server 2000)
Thanks

Dear All,
i have a question abt winCE 4.2 and SQL server CE.
i am using VB.net of Visual Studio 2005
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

Long story short -
Have two C# applications - one WinForms desktop app, the other a WinForms smart device app. Both use SQL Server Compact CE 3.5 to store data locally. Both work just fine.
Now the desktop app needs to open and update the .SDF file that is stored on the Windows Mobile device. (Device will be docked via USB.)
What format would the path to the .SDF look like that the WinForms application would need to specify in order to open it?
Thanks for reading.

Hi there,I sincerely hope that someone out there can help. I have twoinstances of the SQL 2000 Desktop Engine running. One is on my localmachine for development and the other is on another machine on ournetwork which is the production environment. I have built an Access2003 front end application which connects to this database. Thisworks fine locally, as you would expect. I successfully installed thedatabase on the production machine and am able to connect to it viaAccess 2003 (using the Data Link Properties window) and from thirdparty database manager software (similar to Enterprise Manager). I amnot able to to connect to the database via my application.I am using the "sa" account with a strong password. This is myconnection string:strConnection = "Provider=sqloledb;DataSource=server02;UserId=sa;Password=strong;Initial Catalog=Test"The error I'm getting is:"Connection cannot be used to perform this operation. It is eitherclosed or invalid in this context."The connection string is the only thing that changes in my code when Iswitch from my local to my production database. Is there some reasonthat I can't use the "sa" account in this fashion that I'm not awareof? I'd rather not use integrated security for simplicity's sake asthis is a small, internal application. Also, I would have thoughtthat if that was the issue, I couldn't use "sa" at all, even locally.I'm going to post to the Access group as well but thought someone heremight have some advice to offer as well.Thanks,Barb

Hi,
I experienced this problems on both Windows Mobile 2003 SE and Windows Mobile 5.0.
Its native development (c++, oledb, atl and mfc).
It's quite simple to reproduce...
1. open a database
2. open a rowset on table A (whatever, valid of course and with both IOpenRowset and ICommandText), read datas and close rowset
3. power off
4. power on
5. try step 2 with another table (failed on openrowset with error 0x80004005) or try table A (sometimes working because of cached memory, sometims failed on Read Datas).
6. being stuck ;-)
Our work-around was, in case we loose our connection (identified by error 0x80004005 on openrowset), we close it and re-open database... ugly for sure, but working.
What I'm looking now is to use some kind of "detection method" like what people in .Net develoment are using "if ConnectionState.Open <> ...) for reopening my database only on demand...
Thanks in advance for any hints,
Fabien.

Hi everyone,
I am working on a Hospital Information System project with a team of 6.Each one of us builds or modifies a part of the system and shares the project over a common repository. The problem here is that we use the absolute path of the database in our connection string. Although the directory structure of our project is the same for each member, since the main project folder itself is stored in different locations on each person's computer (for example, one may have it stored in c:My Documents and the other in d: My Documents), we are forced to modify the connection string manually each time someone else from the team updates the repository with the database. How do we make the path of the database relative so that we don't have to modify the connection string manually each time after receiving an update from the repository?
Your help is greatly appreciated.

I have a database in development in SQL Server 6.5 that needs to be occasionally deleted and rebuilt from a script when table structures are changed. I found that when very complex queries were performed, the 2 MB default size of tempdb filled up and returned errors, so I went to the Enterprise Manager to expand tempdb, learned that I had to first expand a device to expand tempdb into, and foolishly chose to expand tempdb into the same device space used by my application, instead of into one of the system databases. Now when I try to delete the device in preparation for its rebuild, the Enterprise Manager responds with an error message saying the device can't be deleted because it contains system tables. Is there any way to get the expanded portion of tempdb out of my application device so that the device can be deleted, without reinstalling SQL Server?

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

Hi,
I€™ve developed a BI system using the SQL Server 2005 Developer€™s Edition.
SSAS, SSIS and SSRS have been added to a SQL Server 2005 Standard Edition Server in preparation for delivering the developed database to this live environment.
So I am able to connect directly to the Database Engine, SSAS, SSIS and SSRS successfully from the actual SQL Server 2005 Standard Edition box which is sat on a Windows 2003 Server operating system.
However when I launch SQL Server Management Studio from a desk top PC which is connected to the SQL Server Standard Edition box I can€™t connect to either SSIS or SSRS, however I can connect to the Database Engine and it also seems that I can connect to SSAS OK.
I am using Windows Authentication where the I used a SQL Server account which exists with €œsysadmin€? permissions and this SQL Server account has the same login name as the Windows Server 2003 desktop login.
What do I do next please?

When trying to install Business Contact Manager (BCM) for Outlook 2007, the setup failed and I was refered to a log file in my Local Settings/Temp folder. The log actually says that Business Contact Manager was installed sucessfully! BCM is supposed to install SQL Express 2005 as an instance or as instance if SQL Express is already installed. There is an MSSMLBIZ instance in Services..
Who can I send the Log File to for analysis and the fix feedback?
When I first went into Computer Management and clicked on Services and Applications in the left panel, the error message appeared "Snap-in failed to intialize. Name: SQL Server Configuration Manager CLSID:{CA9F8727-31DF-41D2-975C-887D84903967} This message diappeared when I clicked on Services and Applications again. Under Services, there are 3 SQL services - one is an application that was uninstalled 3-4 weeks ago and I disabled this service. The other 2 are: SQL Server (MSSMLBIZ) and the other one is SQL Server (SQLEXPRESS) When I tried to start either of the last 2, the message appeared: Services "Could not start the SQL Server (MSSMLBIZ) service on Local Computer. Error 3: The system cannot find the path specified. Under Program Files/Microsoft SQL Server/MSSGL.1 folder is mostly empty. So, it seems like the Path in the Registry is not valid and that nothing is being installed in the MSSQL.1 folder. If so, how do I fix this?
How do I get the BCM SQL instance to install and run properly? what do the messages in Services mean and how do I resolve these.
Thank you!
Gary

My organization supports both SQL 7 and SQL 2K. Therefore I have the Enterprise Manager
for SQL 2K on my desktop (it accesses both SQL 7 & SQL 2K, but the SQL 7 EM won't access
both).
I installed the SQL 7 desktop edition on my NT 4 (SP 6) workstation, but only the server (not
client connectivity or client tools).
When I attempt to perform a new server registration using EM (with the desktop server running),
I get the following message:
"SQL Server does not exist or access is denied"
I am attempting to logon as "sa" with a blank password since this will be my very first access of
the installed DB.
Startup of server specifies that the "local system" account be used. Server starts up fine as best
as I can tell.
For client connectivity I have both TCP and NAMED PIPES available.
Any help would be very much appreciated!!!!
Thanks Gary Andrews
andrews_gary_w@solarturbines.com
P.S.
Where blank passwords are used, do I enter a single space or not enter anything
and just press enter?
