i have design a window base application by using VB.NET 2008 and use database SQLCE 3.5 SP1. The application is working fine on all the window 32bits system, but if executive on window 64bits (like windows Vista 64) come out this error message.
[Code]...
i know oledb is not supported in 64b. I have read the application must to be compiled in x86. But it doesnt work.
As i said:
-windows 7 64b
-vb.net in visual studio 2008
-office 2003
I want to access the Windows mobile SQLCE database from the desktop application when device is connected to my PC.
View 1 RepliesA few years ago I created an application using VB6. It works fine on all OS but considering vb6 is no longer supported and it lacks lots of features, I've decided to upgrade to VB.NET. Plus I also want my software to run on all future OS correctly. I was using the ADODC control on many of my forms. In VB.NET, if I go to Tools > Choose Toolbox Items, I see ADODC under the .NET framework components tab. Can I still use this or is it outdated/no longer supported? If I use it, will my software work on 32bits and 64bits systems? [code]But in VB.NET when I write this I get the error As Any is not supported in Declare statements. How should I write this in VB.NET?

i convert to a VB DateTime(), it converts at this way: Day/Month/Year.After that, i insert it to the sql, everything good but the problem is, on the database is always showing as 01/01/1900, what im doing wrong?
Also i put a Console.WriteLine to check if there is any error, no errors as i expected.

I'm attempting to insert rows into an SQLCE database, and it's returning that 1 row is affected, there's no exception, and no syntax error in the query as far as I can see - but it's having no effect, when I look in the table from the Database Explorer.
Here's the code, though it probably doesn't make a difference:
Using conn As New SqlCeConnection(My.Settings.DietSafetyCheckerReportsConnectionString)
conn.Open()
Using cmd As SqlCeCommand = conn.CreateCommand()
[code]....
I have used Access databases before so thought I'd try something different. My problem is that when I try to add a new record to one of the tables in the databasethe code runs through fine, but the data is not added into the table :S have probably missed something simple, but it's been a while since I did any projects using a database.Here's my code:
Imports System.Data.SqlServerCe
Public Class Form1
Dim con As SqlCeConnection = New SqlCeConnection("Data Source=C:UsersMattDocumentsVisual
[code].....
I get an error using the connection string (url...) to connect to my SQL CE saying that "Provider 'Microsoft.SqlServerCe. Client.3.5' is not registered in the local PC.".In my project I have a table connected (with the wizard) to the same database and it works fine, but when i try to connect with my own code it FAIL.

View 1 RepliesI have filled a DataSet from a SQL Server table and I have also set up synchronisation with a local copy (for offline use). The local copy is saved to a SQL Compact Editon database file.

2. Execute a stored procedure (a copy resides in the DataSet) against the SQLCE database
My app currently uses both SQLExpress and SQLCE, depending on the choice of the user.In my database class I have non query command objects for the CE connection and non query command objects for the express version.
Essentially, this is duplicating code as Parameters.Add etc. has to be repeated on both objects.Is there a way just to add do it once on a common object?
Dim MyConnection As SqlConnection
Dim MyCEConnection As SqlCeConnection
Dim MyNQCommand As SqlCommand
Dim MyCENQCommand As SqlCeCommand
I am having some issues with an application written in VB.net.
As part of a routine, an sqlce database gets backed up before the routine then if an error occurred gets restored. I am using system.io methods copy and delete.
I have released all the objects (connections, commands, datareaders) asscociated with the sqlce database by disposing them if they are not nothing. I also do a GC.COLLECT however when my delete command runs, an error message says it is open by another process. The PROCEXP.exe process explorer tool says it is attached to 4 undefined processes. After a while in debug mode, these clear and I am able to delete the file. However this is not acceptable as my program cannot "wait around" until they are released! I was under the impression that object.dispose forced an immediate disposal rather than waiting for the garbage collector to clean up (if you were just to use object=nothing), but still there appears to be a finite time before these objects are released.
My question is, is there an alternative way of checking (programatically in vb) for what is holding open an sqlce database (or in fact any other file for that matter) then killing these processes?
I'm about to pull my hair out on this guys I do not know where I'm going wrong but basically I receive a web request response formatted in XML and I need to insert that data into an SQLCE database. I have tried using LINQ queries but there are no matching ID fields to Join or Group.

I've been messing around trying to get an INSERT statement to work, and because of this, it has created lots of records in my database that I dont need or want.

I have an issue that I can't seem to tackle. Going on 3 weeks. I have a VB.NET app with an sqlce 3.5 database. I have created several tables in this database. I have attached them to my form using DataSet then BindingSets and so forth. Done this many time before. VS automatically created a TableAdapterManager for me.I was having an issue getting the Refresh of the primary key value of a newly inserted row. Ok, find out that sqlce does not do big transaction, or multiples rows at a time, found Beth Massi's blog on how to work around this:Ok, got it somewhat to work, but I had to take one of the tables out of the tableadaptermanager so I can update it by itself so insted of doing this:
frmMain.Validate()
frmMain.bsRunInformation.EndEdit()
frmMain.TableAdapterManager1.UpdateAll(frmMain.DS1)

Getting some errors with a loop. It's a log-in app that has username, passwords & account type stored in a SqlCe database. I would like it to sync with a larger database for updates that has not been made so i left it out but I have started to make a loop that would connect it to the larger DB and if connection failed would try a set number of times before stopping the program. I'm coding this project with Visual Studio 08 pro
Dim conndb As New SqlCeConnection("Data Source = |DataDirectory|\Mydb.sdf")
Dim x, y, z As Double
x = 1
y = x + 1

I'm designing a PC-based app that has a little local database. I'm using VB.NET with SQL Server Compact Edition. The user will only ever have access to one database file, because it's all about storing a user specific data. However I'm thinking of the situation where there could be multiple users that access the PC, each with their own Windows account. So ideally I'd need separate database files for each User.
I'm not sure how to implement this. I was hoping to deploy the 'empty' database as a ClickOnce deployment, but I can't see how I can have a database per user doing this. Also I'm not sure where to store the database files anyway. perhaps in MyDocuments for each user? Or perhaps I need to stick to just one database, but add a 'User' column into every table, so it can hold data for every user. I didn't want to do this though - because I wanted to keep the nice separation between the data offered by physically separate files.
I have a SQL CE database (SDF) that I tried to edit with Database.net v3, but it is now not opening in Visual Basic Express 2010.[code]I've installed SQL Server Compact 4.0 ENU CTP1, but it is still not working.Is there any way to revert the version back? Or anything else I can do to fix this error?
View 4 RepliesI am working on moving applications from Windows 2000 to new server Windows 2003 R2(64 Bit). I noticed that there are some VB programs and config files for those programs have been placed in Windows 2000 Registry. Some other applications are using them from different servers.Why do we use registry here? How can i move these to registry in windows 2003? Can I just move these or do I have to write VB programs to place them in 2003 registry?
