I need to create a desktop program on vb.net , based SQL compact edition. but I do not know how to connect to CE database. I already create the sdf file, but I can not connect it from the poject , is there any way to do it ?
View 1 RepliesIn my IPAQ, I have been using SQL CE for databases with various sizes without any problem. I am creating the databases on my desktop using VS 2005. After I moved to VISTA, I have upgraded my VS 2005 to SP1 and SQL CE to 3.1. My databases which were created before worked without any problem. After I have created my databases via 3.1 on the desktop and moved them to Mobile, I had problems.
1. I specify Max database size parameter as the size of the database
2. If the size of the database is smaller than 16 then I specify 128
3. If the database is old version then program runs without any problems whatever the database size is
4. If the database is created with 3.1 and size is small (20MB, 60MB, etc) no problems arise
5. İf the databse is created with 3.1 and size is large (133MB, 174MB) then dbconnection.Open() command runs indefinitely and program hangs up .
My IPAQ runs "Microsoft Pocket PC Version 4.20.1081" and desktop runs VISTA Home Premium. I have installed VS 2005 SP1.
Thanks for any help
Hello,
we've got a SQL Server 2005 which replicates with an SQL Server Compact 3.5. Every 10 to 20 synchronisations we're getting the error mentioned above. A Soft reset of the device helps to make the synchronization working again.
Why is this error happening and how can we resolve this?
BTW, we've also running system that replicates with an SQL Server Compact 3.0 without having this problems.
Thanks,
Markus

The device I'm working on has a filesystem on compact flash, but we're concerned about burning it up with excessive writes. One solution might be to keep the SQL database in the the object store, perhaps dumping a copy out to the CF as backup. Any pointers as to how to accomplish this? If we were to keep the db in a file on the CF, what's the SQL Server CE behavior for writing to the file? Does it write every time a record is created/updated, or is there any ability to control when the data is flushed to the file?
Thanks from an SQL newbie.
We have a plan to use Microsoft SQL Server 2005 Compact Edition RC1 as a backend. Our Front-end is VS .NET (VB.NET).
We want to know how to edit the Compact Edition database (.SDF). Is there any editor is available right now in the market? or microsoft provided any editor for this.
OR Can i use microsoft 2005 sql server standard edition for this.
Thanks
Is there any way to convert an Access or SQL server 2005 database to SQL server 2005 compact edition database??
Thank you very much!!
I'll try and ask one more time. Does anyone have a clue how to fix this?
"A SQL Server Compact Edition DLL could not be loaded. Reinstall SQL Server Compact Edition. [ DLL Name = sqlceca30.dll ]"
or
"SQL Server Compact Edition encountered problems when opening the database"
"Internal error: The database is not initialized."
I've been fighting this for well over a week now. My XP based version works fine but this error occurs routinely on my CE4.2 device. I cannot find anything meaningful using Google other than 'look for non disposed' replication objects which I've done. Is this bad hardware? I don't believe I'm out of memory as the app is about 1.2MB including about 8 DLL's and GC indicates I have about 300KB of objects at the time of the failure. I also use a bunch of static (global) objects that I use throughout the code.
It would be nice if I could get the lower level error messages causing these failures but that is probably too much to ask.
The odd thing is that it's only the replication engine that fails as even after the failure, the app can reopen the DB and work with the data just fine.
My basic order of the application is...
1 Open DB SqlCEConnection
2 Create/Prepare any SqlCECommand objects
3 Do work here
4 Dispose any SqlCECommand objects
5 Close DB
6 Dispose SqlCEConnection object
7 Create SqlCEReplication object
8 BeginSynchronize
9 ... error here..
10 Dispose SqlCEReplication object
11 Reopen DB SqlCEConnection
I've tried creating the Replication object at program start and that does not help. I'm guessing there is something about .net that I don't understand either with stack space, # dll's or whatever. I've rearranged the order of the Dispose, Create, SQL CE objects to include just about every permutation but still am hitting this same problem.
Are there any tools that can help me profile this app for memory problems or usage? Everything seems geared for .Net and not .NetCF.
thanks.

I am attempting to use the SQL Server 2008 Developer Edition (Management Studio) to create/manage a Compact Edition 3.5 database. My problem is that I cannot even create/open the compact database in Management Studio. Any help would be GREATLY appreciated. TIA
Problem Creating the Compact Database:
Open 2008 Management Studio
From menu choose File | Connect Object Explorer...
Choose SQL Server Compact Edition as the Server type.
Choose <New Database...> as the Database file.
Browse to folder where file will be created (C:MyDatabase#1.sdf was used in my example)
Leave all other field as default selections OR make changes, either way it does not work.

Hello everybody,
Wrote before but did not go any answer , try again.
I have two question about SQL compact edition (SQLCE) (.sdf) and SQL Express edition (SQLED) (.mdf).
I have been testing SQLED and have many tables and data in it.
I want know to test SQLCD and hopefully be able to communicate with the SQLED.
For this reason I was wondering the following:
1. IIs it possible to move all the tables and it constratints into the SQLCE from the SQED ?
2. Another possibility I was thinking about was to use some tables in the SQLED in the SQLCE and move data between these two databases through RDA .
However, does this two versions aloud this kind of communciation...between them....?
Thanks in forehand,
Matilde
Hello
I recently downloaded the sql mobile edition, and then I found out about the compact edition.
I understand that these are relational lite version of sql server that can run on mobile devices.
However, what is the difference between the CF and mobile edition? Why should I choice one over the other?
I have just heard about sql everywhere, seems there are all these edtions and how would you choice the right tool for the right job?
Many thanks if someone could explain further,

Does Sql Server Compact Edition 3.5 support RDA synchronization with Sql Server 2000 database?
Hello,
there are some limitations in SQL Server 2005 Mobile Edition - e.g. there is no TRUNCATE TABLE statement, the UPDATE .. FROM clause is not allowed etc. Are these limitations in Compact Edition too? Is T-SQL in these editions functionally equal or different? Is there any comparison of T-SQL features in both editions?
I'm currently looking at adding a database to my company's WinCE 4.2 -based device, running applications coded with embedded CE 4.0. We want to start tracking potentially large quantities of user data (10K-30K 500 byte records) and are looking at a database engine to support this. The database would reside on the device although we would potentially dump the data from the devices to a central workstation that would be used to pull reports about the data across multiple devices. SQL Server Compact Edition sounds like a possible solution, but I'm unclear if it's supported on CE 4.2 or how to install it if it is. It's clearly supported on CE 5.0, but it may be a while before we upgrade to CE 5.0 or 6.0. I've seen references that say that SQL Server Compact Edition is the same as SQL Server Mobile Edition, and references that Mobile Edition is supported on CE 4.2, but I'm unclear if I can install and use SQL Server Compact Edition on CE 4.2 or if I'm on a wild goose chase. If not, can I use SQL Server Mobile Edition and migrate to SQL Server Compact Edition when we upgrade CE to 5.0 or 6.0? If not Mobile Edition, what about Microsoft SQL Server CE 2.0? Is that going too far back in the archives?
Thanks for any guidance/enlightenment you can offer.

I am trying to make a simple example like sql management studio but stuck in the get table names part :) in first step. are there any easy way to get just table names from sdf file ?
I have tried to use SMO but no success.
Regards.
We have been using Sql Server 2005 Compact Edition 3.1 RDA synchronization method successfully on Sql Server 2000 database. Recently we moved the database to Sql Server 2005, sync doesn't work anymore, it just hangs on one table. On further investigation, we found out that it's the index on that table that causes this. We removed the index, it works fine. We are wondering the root cause, removing the index is not a solution for us. Any thoughts?. Thanks.
View 1 Replies View RelatedI am writing an application that is designed for the desktop, or small group (3 or less) desktops. The application is being deployed using the Cassini web server as a complete "embedded" solution. I wanted to use SQL Server Compact because of its small footprint and because of the synchronization capabilities with SQLServer. Also, it is very easy to deploy vs. SQL Server Express. The idea behind this APP is that someone might use it locally and then decide to subscribe to the service and then connect the same application to a web services application.
That being said, and with knowledge of Microsoft's stance on SQL Compact under ASP.NET, I have most everything working and it works great except for one thing. When I add a SQLDataSource to the page and set the connection string to my file and the DataProvider to System.Data.SqlServerCe and then bind a data grid to the SQLDataSource, it runs fine on my development machine, but when I deploy to my clean test machine, I get an error when the page loads saying:
Unable to find the requested .Net Framework Data Provider. It may not be installed.
I can create a dataset in code (in fact,in several other places I do) and it works fine. It is just the SQLDataSource(s) that are throwing this error. I have a copy of System.Data.SqlServerCe.dll in the bin folder and I have all of the compact DLL's in the bin folder as well. I can't figure out what I need to do. I also have a reference to the System.Data.SqlServerCe in the web.config file.
Can anyone help?
I am using SQL Server Compact Edition under ASP.NET. I am aware of the limitations and warnings from Microsoft for SSCE under ASP.NET, but this app is designed as a desktop deployed ASP.NET application running under the Cassini web browser. I wanted to use SQL Server Compact because of the RDA capabilities with SQL Server without the overhead of installing SQL Server Express. There would be 1-3 users at most running the application. SSCE seemed to make the most sense.
That being said, I have everything working fine except for this. I have added several SQLDataSource controls to several web forms and then I have GridViews bound to these controls. I like using the controls because of the built in sorting, grouping and updating I can do. When I run this on my development machine, it runs fine. When I move to one of my clean test machines and install the app, the SQLDataSouce controls throw the following error:
Unable to find the requested .Net Framework Data Provider. It may not be installed
I have the System.Data.SqlServerCe.dll in the bin folder along with all of the files from the the SQLServer Compact 3.1 install, a reference to it in the web.config file etc. In fact, I have several other database related datasets and tableadapters that are created throughout the application and they all work fine and can access and display data from my sdf file. It seems to only be with the SQLDataSource controls.
Any help would be greatly appreciated.
I'm trying to start an application in C# with visual Studio 2008 and I want to connect it to a SQL CE 3.5 Database (local .sdf file).
I only found samples or How-to guides that use the wizard to add the datasource and the way dragging the dataset to the form. All things binded to the database where you don't have to do coding.
I don't want to have the binding navigator bar, I just want to use text box, date picker and buttons and Save that to the database myself. That way I think it will be more easy for me to validate or manipulate data before the insertion in the DB.
Some time ago a make an ASP.net that was doing same kind of thing with an Access DB...
Hope this can help to show what i really want...
(sorry for my bad english....)

Hi all.
We are developing a desktop windows forms app that uses tha database as storage for application configuration.
It may be used by one user locally OR used locally by multiple but sharing the database.
Now, i'm really sure that I have read that sharing the .sdf file over a network is supported and thus have started developing against the 3.5 compact db (sdf file).
But when testing this scenario we get a message that sharing over network is not supported. I'm really surprised and frankly puzzled since I know I have read about this being supported.
So, can someone more into this subject exlpain to this to me? Is it supported, and if not, should we use the express version instead?
Also, if we have to change strategy, is there an easy migration path regarding development (app. is not even in beta stage so no migrations will be necessary with customers.).
Thankful for any help since this might cause a lot of extra work...
If this leads down the synchronization path, could someone please explain how this is set up. Is it one "master" that acts as a publisher?
If we would like to have the solution where several users access the same db-file (be it sdf or mdf), do we have any choice here?
/Regards
i had read information about sce and i had not unsderstood a little thing:
is it possible or not to use a dataset with that version of sql server? i have a class that access the database with some functions and one of then return a dataset. the dataset is not to be used because it does not make sense with sql server compact edition or it cannot by use at all cause sql server compact edition does not support it?
thkx and by the way i think that it's a great product!
Is it possible to run SQL Server Compact Edition as a standalone application from a DVD?
i.e. it would not leave anything installed on the users computer after the DVD was ejected.
Dear all, Anybody knows where to download the beta release of SQL Compact Edition 3.5. Please provide the URL to download this 3.5 of SQL CE. Thanks Gops Sofist India gopalan@sofist.com

Hello
We currently use SQL Mobile and SQL Server 2005. We depend heavily on merge replication for data to the field handheld devices.
We are going to be starting some new projects and I was wondering about moving to SQL Compact Edition as the first step to migrating all of our applications.
I am concerned, however, about the server side and replication. If we simply deploy SQL Compact Edition will there need to be any changes to the server for replication?
Thanks,

I have a Symbol MK1200 device (Intel XScale processor) running CE.NET 4.2 and when I try
to reference any SQL objects I get the error:
Can't find PInvoke DLL 'sqlceme30.dll'
The documentation says that Compact Edition is supported on CE.NET 4.2,
(ms-help://MS.SSCE.v31.EN/ssmmain3/html/ee220634-55c9-4123-85c4-4e6ceb07f942.htm)
but I came across a hotfix (http://support.microsoft.com/kb/924811/) which
contradicts this and says CE.NET 4.2 is not supported by default.
Can someone clarify this for me? I know that VS.NET 2005 doesn't support debugging of CF 2.0
apps to CE.NET 4.2 devices but I thought I could manully deploy a CF 2.0 SP1 application with SQL
Compact Edition (although I'm still not sure whether I need the hotfix) ?
Either way I've been playing around and here is what I found ...
1. I installed CF 2.0 SP1 and verified a simple 'Hello World' application could deploy. All worked ok.
2. I downloaded & installed the SQL Compact Edition CABs on the device manually from
'SmartDevicesSDKSQL ServerMobilev3.0wce400armv4'.
I opened Query Analyzer on the device and it worked i.e. I could open a database, run query, etc.
3. I modified my application with the following sample code:
try
{
SqlCeCommand sqlCmd = new SqlCeCommand();
}
catch (Exception exception)
{
MessageBox.Show(exception.ToString());
}
Once again, just deploying (not debugging) the app. and got the error above 'Can't find PInvoke DLL 'sqlceme30.dll'
4. I installled the HotFix from http://support.microsoft.com/kb/924811/, now Query Anaylzer did not work even though it did work pre-hotfix install, and I'm still getting the same error when I test my code.
Can anyone shed any light on this? It's driving me up the wall ;o)
I have not seen much info on this so I thought I would ask the forum. I have VS2005, no SP1 and SQL Mobile installed on my computer. I started developing an app for Windows Mobile 5 using RDA and it appears to work fine. Now I want to know what happens to SQL Mobile if I install SQL CE. Is it going to affect my app? Do I have to install the SQL CE merge replications tools for IIS again? I already have them for SQL Mobile? Will this affect the operation of my app? It looks like the installation procedures call for installing SQL CE tools to VS2005 before installing VS2005 SP1 then install VS2005 SP1 and finally install SQL CE tools for VS2005 SP1. Any help, thoughts or experiences involving this would be appreciated.
View 3 Replies View RelatedIf my research is correct SQL CE as of this date does not support STORED PROCEDURES (queries).
If this is true, how can it hope to compete with MS ACCESS or MS Foxpro as a Desktop database.
This seems to be a lot of hype for something that appears to be totally in-adequate.
I thought this was a way to wean off of MS ACCESS.
Can someone tell me what I am missing ?
Thanks
