Do While rdr2.Read()
Dim var1 As String = rdr2.Item("Week").ToString
Dim var2 As String = rdr2.Item("L1").ToString
Dim var3 As String = rdr2.Item("L2").ToString
It generates the following error: A first chance exception of type 'System.Data.SqlServerCe.SqlCeException' occurred in System.Data.SqlServerCe.dll
Interestingly, if I use a numeric value for the variable it for LSArraytemp, it writes to the database no problem at all.

I have a VB app that uses a sqlServerCE database. Everything works quite fine on my computer.
When I try to install it on other computers I run into problems. The message "Unable to load the native components of SQL Server Compact corresponding to the ADO.net provider of version 8080"
I am testing on a Win XP virtual machine.
My first attempt was to use InstallShield LE to create the installer. I defined ServerCE as a prerequisite and when I check in add/remove programs it exists, but I still get the error.
Then I tried building the installer with the Microsoft installer. This adds the dll to the program directory automatically, but I still get the error.
I read the KB article referenced (874247) and recompiled the app as an x86 application only, and rebuilding the installer, but have the same problem.

I made a simple sql ce database with one table with the data explorer. Then I added the reference System.Data.SqlServerCe.dll to my project and I added this code:
Imports System.Data.Common
Imports System.Data.SqlServerCe
Public Class Form1
[Code]...
What do I wrong? The sql server ce (3.5 sp1) is fully installed with the vb express edition.

I am using VB code behind in Visual Studio 2008 to process data but can't figure out SQLConnection problems. I copied and pasted the connectionstring for my database from the explorer properties window but when I paste it inside the parenthesis of SqlConnection() it gives me an error. Also if I name a variable " dim myconnect As New SqlConnection" in does not give me all of the methods or attributes that are associated with it. Is this a Express Edition limitation or do I need to make some specific declarations to get it to work. this is what I have so far
Dim
connectString As String
Dim myconnect As New SqlConnection()
[code]....
myconnect. If I try to put open() at the end of this it says its not a member of SqlConnection. I have a dataset but no way to insert into the database

I am trying to connect to a database in VB 2008 express the book I am using is for an older model of VB. The book says to go to view and click on server explorer, and then a database wizard should open. VB 2008 express doesn't have a server explorer under the view section. I know what code I need to enter into to the two buttons I have I just do not know how to open the wizard.
