Hi,
I am a total beginner to Pocket PC, and a 2-month beginner to SQL Server 2005 and Visual Studio 2005. I made a database Pillbox.mdf, and wrote a Windows Forms program to access it. It's really easy. I just added a Data Source, chose tables and Stored Procedures, and dragged them onto my forms. It automatically created adapter classes and a DataGrid for me.
Next, I wanted to do the same thing for Pocket PC. I did the same drag and drop thing, and was happy to see the empty DataGrid in the emulator (design-time) form. From here on, trouble. When I ran it, it said it could not connect.
So some questions:
1) Does my connection string have to change? It has 3 parts: machine name, database name, and security spec. It specifies my machine name. Is that ok? Is it known by the Pocket PC, or do I have to specify http something? Does my machine have to change any settings to become a "server"? It's just a standalone PC with no network. I understand the emulator chooses to pretend that it's not "on" my computer. Is the database name known by the Pocket PC? (Same type of question.) And is Windows authentication ok on a Pocket PC? Or must I create a name/password pair on SQL server?
2) When I went to modify my connection string, I noticed a setting to specify the Data source. For SQL Server 2005, it asks me for a dbo, but for SQL Server Mobile, it asks me for a *.sdf file. What type of file is this? Is there a way to generate this from my other database? Is it not possible to have the the Pocket PC app point to the same database as the Windows app? Oh... does the sdf represent the Pocket PC's local database? If so, then my question is just how to populate it. But I will also have to update the main database at some point. I guess I'm confused about how Pocket PC's are supposed to work.
3) Do I have to deploy SQL CE or something? I think I read that Visual Studio does it automatically. It's a bit hard reading blogs because many comments talk about things that are now contained in VS. One blog was talking about 7 dlls that need to be downloaded to the Pocket PC.
4) My application just has to get a table, store it on the Pocket PC, and allow the user to modify and update records. The bandwidth should be low, as the table is small and updates should not be frequent. Is this a reasonable design? What I am asking is if it's ok to have direct database access, or if I should package up the data in some custom format, and use a Web service to pass the data back and forth. I have read and understood articles why you should not pass a Dataset in a web service, but the point was just that web services can be interoperable, so why spoil that with MS-only Datasets. In my case, I just want to get this simple app up and running quickly.
Thanks in advance.
Hello
i am working on a project in which i have to handle redundant servers.
There are 2 Sql Servers which are online.one is the primary and the other is a redundant server. The application reads data from primary in normal conditions.But data will be updated to both servers.
in case when primary server goes down the data retrieval is from the redundant server which now acts as the primary server.
i should monitor in either case when the server is up have to synconize data from the other server.For this case i have used DTS to copy/append tables.
My concern is will this update all the data that is to the database,even while there is an update of data during when the DTS is running.
As servers will be running for 24 hrs

i have 4 databases:
DA
DB
DC
DD
Database D has three instances:
IA
IB
IC
I would like to syncronise information to move from instances in DD to the appropriate other databse
e.g:
IA => DA
IB => DB
IC => DC
is this possible using code or features in sql server 2005?
thank you
How can I to syncronize two database with the same structure ?

View 1 Replies View RelatedHi All,
My question is regarding syncronization between two databases in MS SQL Server. If we wanted to do MERGE REPLICATION then we can set up pulishers and subscribers using the PS/SQL script (stored procedures) without having to use Enterprise Manager gui tools. I see that after you set all the publishers, distributors and subscribers and you want to start syncronization explicitly the only way you could do is go to Enterprise Manager and find the Publishing/Subscribing Items and right click on them and choost "Start Syncronization" (Sorry I have omitted the nitty-gritty details about how to find those Publishing/Subscribing items in Enterprise Manager).
I am wondering whether we could trigger the start of syncronization using any system stored procedures or without using Enterprise Manager.
Please let me know if you have any idea about it.
I will highly appreciate your response.
Thanks,

Hi,
I am developing an applicaiton through which, i want to print from pocket pc emulator 2003. I am using PrinterCE.NETCF SDK to do this task. I am able to print from my applicaiton like we do in ASP (Printing one line at a time). In PrinterCE, there is an option of printing the output to a file. But, I am not able to find how we do it.
So, I want to know how we can print the output through PrinterCe into a file. Can anybody help me??

Hi,
I'm a developer of VB.NET mobile applications at work. We have used Access in the past, and manually pushed flat files to and from the scanner. We are now exploring SQL CE.
Trouble is, I am having a difficult time figuring out how to open SQL CE databases on the Pocket PC emulator. I've worked more on the middleware programs in the past - and have just dealt with ADO.NET connection strings - not the actual development on the scanner itself.
I am try to figure out how to actually connect to SQL Server CE on the Pocket PC 2003 SE emulator.
When I deploy the application on the emulator, it installs SQL Server CE onto the emulator. However, I'm not sure how to install the sample database (starting off with Northwind.sdf for testing purposes) onto the emulator. I'm also not positive the connection string is correct - as it seems to be different than typical ADO.NET.
Here's my code (for connecting to the database) so far.
Code Snippet
Public Class SampleInventorySystem
Private _conn As SqlCeConnection
Public Sub New()
' This call is required by the Windows Form Designer.
InitializeComponent()
_conn = New SqlCeConnection("Data Source = .Northwind.sdf") 'This is one of 'many connection strings I've tried
End Sub
Private Sub SampleInventorySystem_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
Dim cmd As New SqlCeCommand()
cmd.Connection = _conn
cmd.CommandText = "SELECT [Employee ID], [Last Name], [First Name], Photo FROM Employees"
Try
_conn.Open()
Catch ex As Exception
MessageBox.Show("Error opening database", "Error")
End Try
End Sub
End Class
When I deploy the application, the Try Catch block catches the error "Error Opening Database". I've also tried putting the full path for the connection string. Is there a folder which I should directly put the .sdf file into the emulator - similar to the folder directory of the scanner? (i.e. Storage Card/...)
Thanks for your help!

Hi,everyone!
I'm new to this forum and also new to Visual Studio 2005 .NET.
I'm going to develop a pocket pc(windows mobile 2005) application which needs to save some data introduced by the user.Later that data should be syncronized with MS SQL Server database.
The application is going to be developed using Visual Studio 2005 with c#.
So I'm doubting wich is the best way of syncronising the data between Pocket Pc and a Desktop PC.Should i use MS SQL Server Mobile(RDA,Merge Replication) or XML(Xml Web Services) would help me better?Or is there any other better way of data syncronization/storage?
Could anyone help me,or post some links + code samples,please?
Thanks!
When I try to do a pull using a view I'm getting the following error message:
€œThe query cannot be tracked. There might not be a primary key, or the query might involve multiple tables. [ Query string = SELECT * FROM DATABASE_NAME.viewname ]€?
but when I do a select col1 from view I get my data. The view has some inner joins included in it, could that be the issue?
NOTE: this is from my handheld device, its not SQL Server related. I posted this earlier in this forum but it was moved to SQL Server.
I get the error on my handheld device and handheld device only
I have a Pocket PC application (VS2005, SQLCE 2005, Windows Moblile 5.0, SQL Server 2000) that can pull data with no problem but produces an error when an RDA push is attempted. The error message is: Error Code: 80072EE4 Minor Err: 28037. The information in TechNet has description of : A request to send data to the computer running IIS has failed. For more information, see HRESULT. It does produce a log in the folder for SQLCE 3.0 and has the following message: Hr=80070585 ERR:REQUEST NOT QUEUED for ulRSCBId = -1. Not sure if this means anything because I can't find much information on it. Anyone have any ideas on what this could be? Do I display the HRESULT the message mentions in Visual Studio debug? We have this working on our development server so I am not sure what is different here.
View 5 Replies View Relatedhi i tried to view a replication on a pocket pc app that i created. and i used the following code

try

repl.AddSubscription(AddOption.ExistingDatabase);
repl.Synchronize();
}
catch (SqlCeException e)
{
MessageBox.Show(e.ToString());
}
when i run it i keep on getting the error:
The SQL Mobile Subscription already exists. Publisher, PublisherDatabase, and Publication for this subscription should be different from any existing subscription.
However, i can still view the contents of the datagrid that refers to the database subscription.
1. What should i do in order to stop getting the error above?
2. If i edit the contents of the datagrid in the pocket pc app how will i update the replication in the sql server? thanks

I asked this question on another forum, and it was suggested that using SQL Server might be the way to go.
What I would like to do is create a database that can store detailed employee payroll information for workshop production. Included in this db would be employee info, job details, hours worked, pay rate, and so on and so forth. That will probably be the relatively easy part.
I would like to allow supervisors (job coaches) to enter this data on a Pocket PC (windows mobile) device, and then be able to synchronize the pocket pc to a workstation, allowing their data to be uploaded to the main database at the end of the day.
Can that be done using SQL Server as both the main networked database as well as having it (or a lite version of some sort) installed on a Pocket PC for synchronization purposes as described above?
Thanks for any input.

Thanks in advance
I'm writing an application for Windows Mobile 5 / Pocket PC using VB.NET 2005. The database is connected using an instance of SqlCeConnection and updated by an SqlCeCommand.
The application can perform select queries on data originally entered into the database through Visual Studio, or perform update / insert queries at run time. Anything inserted or updated can be returned by a select query whilst the application is running, however, anything I have inserted or updated doesn't appear to be written to the SDF file and hence is not in the database after restarting the application.
Am I missing something that's different between performing queries on an SQL CE database on Pocket PC and an ODBC source in a normal Windows application?
I am using VS 2005 to develop a Pocket PC 2003 application and for some reason I dont have the ability to assign my datasource to a SQL Mobile Database?
When opening Server Explorer, right clicking Data Connection, Add New Data Source, Change Data Source, the only options I get are
Microsoft Access Database File
Microsoft ODBC Data Source
Microsoft SQL Server
Microsoft SQL Server Database File
Oracle Database
