I am writing a Desktop application accessing a SSCE database. I am running Windows XP SP2, VS2005 SP1, and have SQLServerCE3.1 installed. Debugging the application shows that ds.m_spInit->QueryInterface() returns E_NOINTERFACE. I have checked that SSCE runtime library is installed, IDBCreateSession uuid exists in the registry and m_spInit.CoCreateInstance(CLSID_SQLSERVERCE_3_0) return S_OK. Can you suggest me what need adding/installing to get the CSession.Open(datasource) working?
I am thinking of using my web database as the database to use for my program, though not sure how feasible due to connection speeds and having to transfer that info.
what I am using as the connection string is
con.ConnectionString = "Data Source=databse ipadress inserted here; Initial Catalog=databasename here;Integrated Security=True"; with real data obviously inserted into the ip and tables, but when i try and send values there it just hangs and then crashes. I am thinking its not finding the database. Is there something else im to do?
I am using the exact same code as when i use my own machine as the server, and it works great that way, only thing different is the trying to send to the web server.
The sample application provided with Access Database Synchronizer fires a "A request to send data to the computer running IIS has failed. For more information, see HRESULT." exception on my WinCE 4.2 device.
I debugged it with VS2005 to see what was going on and found that the problem resides in the line:
m_connDesktop.Pull("MSysObjects","SELECT Name FROM MSysObjects WHERE Type=1 and flags=0",accessSysConnectString,RDATrackOption.TrackingOff,"Err_MSysObjects");
It seems that connection m_connDesktop is ok but calling Pull method fails.
I've verified that SSEvAccessSync service is started when ActiveSync detects device connection and that firewall rules are correctly updated.
Also, i verified my System.mdw and i discovered that there is no "MSysObjects" table (only MSysGroupList, MSysGroupMembers, MSysUserList and MSysUserMemberships queries are there).
Do you think the problem is there?
How can i solve it without damaging System.mdw?
I cannot figure out what's the purpose of this line of code, can you help me?
you see these are the requirements.. 1. there is a text file named "Loan" 2. i must create a program using ASP.net wherein the text file can be imported in the system. 3. after importing, i must save the whole text file in a database.
my questions are:
1. what code can i do to open up a text file? 2. how can i save the text file into a database? 3. is there any way that i could import the file and view its content in my application? 4. after viewing, how can i save the text file as a text file in a database?
i have an application that uses sqlce.. now i want to install sqlce with my installer instead of seperate installer... could you please guide me how can i do this? i have created installer for my application but how to integrate sqlce with it...
I was thinking of replacing my desktop programs I do in Microsoft Access to SSEE. I am getting up to speed by some books and tutorials.
How would I distribute a program that has a SSEE database? I currently have in my application startup path a folder called "Database" that contains the .mdb, could I do the same thing with SQL Server. If so, what does that do to the connection string.
I am interested in synchronising 2 sdf files which are sitting on 2 different PDAs and I want to synchronise both of them with or without desktop application. C# applications are used to talk to the applications.
Is it possible or not and if possible how can i do that. Any code snippets or any links to similar forum posts or anything will be of great help. I am a C# programmer but not SQL Developer.
I was migrating one of my applications to VS.NET 2008 to start testing the new platform and encountered an error. One of my application requires the use of System.Data.SqlServerCe namespace to create a SQL Server CE database on a desktop machine.
The error is raised when I try to use a SqlCeCommand to insert rows in a table using parameters. If the order of the fields in the INSERT command does not match the order of the fields in which the table was created, an error is raised.
Investigating further, I noticed that the INSERT command was trying to insert the value of a parameter in an incorrect field. For example, the value for the field23 was being inserted into field22.
It looks like the SQL CE engine is rearranging the fields in the INSERT command to match the order of the fields in the table, but forgets to rearrange the parameters of the SqlCeCommand as well.
I give the example codes in the next posts. I will give it in both VB.NET and C#.
For both versions, you just need to create a Windows Application and add a reference to System.Data.SqlServerCe.dll. Insert the corresponding code into the Form1 partial class.
In the example, the constant RaiseError can be set to Boolean.True in order to raise the error. Set it to Boolean.False to execute correctly.
Am I correct in assuming that installing a SQL EE application on to a local runtime desktop would require a lot of experienced user intervention to install the SQL to each local cpu? Can a SQL app be installed automatically w/o a user intervening?
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
I've just recently downloaded Visual Studio 2008 Express which comes with SQL Server 2005 Express and SQL Server Compact 3.5, both of which were installed when I installed the products.
I've been following the tutorial videos and trying some stuff of my own and I just can't seem to get a Compact 3.5 database to actually update! I'm doing EXACTLY what is shown in the tutorials and th dataset is being updated - changes and added records - and they will show up in a DataGrid control as expected, but when I accept the changes - nothing is changed and/or added to the actual .sdf file. When I open it again, it's the same as it was before. Using exactly the same code but with an SQL Server 2005 Express database (.mdf), updates are fine.
First I created a dataset that connects to the SSCE 3.5 database .SDF file. Then I simply drag the table from the dataset to the form which creates Dataset, Table Binding Source, Table Adapter Manager and BindingNavigator items, in addition to the toolbar and DataGrid controls. The code generated from this is below. I have added the Try/Catch block and messages to see if any errors are ocurring.
Code Snippet Public Class Form3
Private Sub TblMessageTypeBindingNavigatorSaveItem_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles TblMessageTypeBindingNavigatorSaveItem.Click
When I run the app, the data in the database table is displayed correctly. If I make a change and add a record then click the Save button, I get the expected "Changes Saved" message indicating that there are no errors. When I look a the contents of the table, the changes and additions did not happen and the data is exactly the way it was before.
I had the full SQL Serer 7.0 installed as well so I thought there might be a conflict or something became corrupted. In uninstalled SQL Server 7.0, SQL Server 2005 Express and SQL Server Compact 3.5. I "repaired" VB 2008 Express which reinstalled SQL Server Compact 3.5 and separately reinstalled SQL Server 2005 Express. Same problem.
As I mentioned above, what gets me is that if I use the same setup for a SQL Server 2005 Express database, changes and inserts work just fine. (Used the Northwind.mdf (Express) and the Northwind.sdf (Compact) sample databases and created my own sample .mdf and .sdf databases - same results.)
I've looked at whatever I can to see if I can find the problem but just can't put my finger on it. Very frustrating.
Does anyone have any advice on what I might be doing wrong with Compact or if there is something I've missed or if there's a property somewhere that needs to be set, or perhaps a configuration issue??
I've found a two different answers for this question:
one - on the http://support.microsoft.com/Default.aspx?kbid=920700 site where on the Performance improvements section there is a 128MB value in the Database size.
other is in the product datasheet there is a information that this version supports databases up to 4 GB.
What tool should I use to view SQL Server Compact Edition database?
I have VS2008 Professional, but I didn't find any tool in the installation. So I tried to install the SQL Server Developer Edition, which is included in the VS2008 package, but the installation has quit saying the that there is nothing to upgrade (there is probably newer version of SQL installed by VS2008 itself).
I also tried to download and install SQL Server Managment Studio Express. The installation went well, but then I wasn't able to select any SSCE database (there was only SQL Server Express or something like that selectable).
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?
I am developing a windows application that needs to communicate with a remote SQL server 2005 database. Server allows remote connections and MSDTC service also running. Do I need to run MSDTC service on the client machine where I use desktop application ? any ideas ? It's throwing some error like 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.
But my SQL Server allows remote connection, and I am able to do a select statement. But when I insert/update anything, it's throwing this error. I guess some problem with MSDCT. Anybody have any idea ?
I get the below error only when my IDE open. It connects well when it is found closed. [SqlException (0x80131904): Cannot open user default database. Login failed.Login failed for user 'JPASPNET'.] I could solve this by giving the logged in windows user to impersonate under IIS window > WEBSITE > ASP.NET tab > EDIT CONFIG > APPLICATION tab But I wish someone could give me the proper solution. I almost tried all from giving ASPNET user as a administrator to configuring the same in Express management tool. Environment: XP pro, VWD and SQL Express
I know that with traditional SQL systems, it is important to only open connections to a sql server when they are needed. However, since there is no "server" in mobile apps, is it bad practice to leave one open throughout the duration of an application?
The application is going to be constantly reading and writing to the data tables and it seems like it might be a good idea to leave it open.
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?
Hi, I would create a vb2005 application that allow me to edit a sdf database stored into a pda connected at pc with activesyn directly on my desktop as well as "SQLCE Database View". How can i do it??
I hav emulator Windows CE 4.0 with Visual Studio 2003, C#.
I want connect to sql server 2000......after read all posts of this subject and try all varieties modes of connecting string.....in sql profile i see that application in emulator try to connect the sql server but i have the same exception :
I am dealing with an old ASP.NET 1.1 web app that I want to fix and update. The existing site has an SQL database on the web host's SQL server. I want to rip a complete copy of this database (it isn't large, only 9MB) onto my desktop computer, so I can alter it and "bench test" the changes I'm making to the overall application in VS2005.
Now, I have tried to yank a copy of this database and its structure using GUI programs like Visual Studio 2005, SQL Studio Manager Express, and EMS SQL Manager, none seem to offer a "Save As" option. While I can easily make changes to the database and its tables on the web host's server (sql.hostname.net) with no problem, I can't figure out how to pull a copy off of their server and onto my machine...
Does this problem have a very simple solution that I am overlooking?
I have searched through this forum and the news group
microsoft.public.sqlserver.ce
for this topic. I only find a post from Darren Shaffer and I requested a document.
Unfortunately, there is not a clear example of how to create a mobile database (sdf) on a desktop machine which contains VS 2005 and SQL server 2005 by using Visual Basic 2005.
I am sure a clear example in VB for this problem would help a lot of people. Hence anybody who knows how to perform this task, Please help these people.
I am running 7.0 standard desktop on Workstation 4.0 and have run into a database size limitation of 10GB. I have all the newest patches and have found no documentation that refers to a 10GB limitation. A September copy of VBA developer says that this edition has a limitation of 4GB while the guides say that the Small Business Server edition would have a 10GB limitation. All other forms of documentation say that there should be the standard mega-terabyte limit. I'm completely confused by this [lack of] documentation. Any help???
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)
I have developed a C# desktop application which uses SQL express as its database. It works just fine as I installed the application, used SQL express Server Management Studio CTP to create database with tables , stored procedures etc.
Now, I want to create an installer that will not only install my application to other machines but also create the database with all the tables and stored procedures with it.
How do I do so? I searched the answer in several places but none worked out for me. Can anyone please help me on this??
For your convenience I'm giving the following informations:
Database name: NorthPoleSQL sever Name: IshtiaqueSqlexpress (used Windows Authentication Mode)
I have detached the database from the original machine and have the NorthPole.mdf and NorthPole_Log.ldf files. I want to use these files and create the database in target machine rather than writing sql scrips and executing them.
Please help me with a descriptive, step by step instruction as I am new to this technology. Thank you.

I don't know why my application on the internet try to access the SQL Server 2005, when the host still having the 2000 edition. I put the following connection string: Data Source=##DBSERVER##;Initial Catalog=##DBNAME##;User ID=##DBUSER##;Password=##DBPASSWORD##;
Isn’t everything fine with that? I created the table by host but dosen’t work. I’m wondering if can I conect straight with Data Base, without register in the server, like with mdb?
This is the error that I’m getting. 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: Named Pipes Provider, error: 40 - Could not open a connection to SQL Server)
