I've developed a software using VB.Net and SQL compact edition database. (.sdf file) Now i want to add my .sdf file to setup file. I've search internet and create setup file. when i install the software, it is created new folders in program files including my database file and exe file. after double clicking exe file, it is open the software. but when using, it's shown a message "connection current state is closed". but when i run my vb project, it is working well.
Other details.
1) I create data base inside of /bin/debug
2) I've created setup file using this method. File menu --> add --> new project Then, Setup and deployment -> Visual studio installer After that I selected Setup project, then click OK.
3) I add database using this Right click on setup file -> add -> file (In solution explorer window) Then i selected my .sdf file.
This is my connection string
CODE:
It is created only 3 files in Program files.
1. my exe
2. my sdf file
3. System.Data.SqlServerCe.dll file
can the code below be modified for use with a SQL Server Compact edition DB? Public Function Querymode1(ByVal SpecifiedYear As String) As DataSet
'Dim DBConnection As New System.Data.OleDb.OleDbConnection("Provider=Microsoft.Jet.OLEDB.4.0;Jet OLEDB:Database Password=charlyX;Persist Security Info=False;Data Source=c:mydata" & DBName)
Dim DBConnection As New System.Data.OleDb.OleDbConnection("Provider=Microsoft.Jet.OLEDB.4.0;Jet OLEDB:Database Password=charlyX;Persist Security Info=False;Data Source=" & Trim$(MitsSetUpFile.MainDataLocation) & "" & MDBName)

I am trying to do multiple joins within a single query in SQL Server CE. I know that SQL Server CE doesn't support multiple SELECTs but I can't find any information on multiple INNER JOINs. I keep getting token errors on ProjectItemMaster (after the FROM) and the first INNER JOIN. Warning this is a big ugly query used to generate reports.
[Code]...
If I can't uses multiple INNER JOINs I can I break the query down into a number of different queries but I would prefer not to. So it is easier to maintain a SQL Server CE and an SQL Server version of the program.

View 11 RepliesI have an application that is currently using DAO and would like to move it to ADO.Net. The problem I'm having is that when I do, I cannot do any queries that take variables if the database is Access or SQL Server Compact Edition. For example: SELECT RecipeName FROM tblMasterRecipe WHERE CategoryID = iCategoryID..The database is a local standalone database. Of course if I use the Standard SQL Server I can add parameters just fine using the TableAdapter Query Configuration Wizard. How do I do something similar for Access or SQL Server Compact Edition? The Create new stored procedure radio button is greayed out when the database is Access or SQL Server Compact Edition.

View 1 RepliesMicrosoft Access 2007 A Students.mdb database file Visual Basic 2008 Express Edition. I was informed that one can connect to Access files with ease from the Express Edition and most of the tutorials on the internet also show this however I am encountering a problem.
I open Visual Basic 2008 Express Edition Start a new project, with a form, and then click on the Data window, and add new data sources from the Data menu.
I click on database. The problem starts with the data connection. I click New Connection Change the Data Source from Microsoft SQL Server Compact 3.5 to Microsoft Access Database File and instead of then leading back to the other window (as happens on the tutorials for me to browse for the mdb file). Another window pops up asking me to Add a Connection.
It has the data source listed as Access and asks for a Connection String under the misc section. I type in
CODE:
When I click on Ok I get this error: Format of the initialization string does not conform to specification starting at index 0.
The Test connection button works and says connection success whether the Connection String field is empty or not but when I click OK it still gives me the same error. So I can't leave it blank either
So basically I can't connect to the Access database since I can't change the connection type and it won't just let me browse and add the file anyway.
I am building a VB 2008 Express Edition application.I have built a database (with a single table) using SQL Server Compact 3.5 and have connected it to the project. I am able to view and edit the data using a DataGridView on a second form (tutorial made this very easy). I need to work with the data in the table within the application. how to easily load the entire table into an array or even read the table a row or cell at a time so that I can make all of the data available for manipulation within the application (the tutorials only seem to show how to display the data).
