Cant Insert Data To SqlCe Database
Sep 14, 2009
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

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 am trying to add a new record to a table, well first it checks if there is already a duplicate record in the table, and if not it makes one. If there is a duplicate, it tells the user.[code]

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 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)

I got a system which i want to insert, delete, update the data into my database and the data from database will be display using datagrid. The below is the coding for one of my button, delete.
Private Sub btnDelete_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnDelete.Click
Try
btnSearchEmpNo.Enabled = False[code].....
Now I wanna set when user click on this button to delete a employee (for example) then the datagrid that i have in my application will not show the data of the deleted employee but in the background, the employee haven't been deleted from database.The employee only will be deleted from database when the user click on SAVE button.I know this application have to use RowState but how?

What I want to happen is that the button from my system will remove the previous data from database and then insert new data to database from text file. Im done with inserting new data. The thing is that I dont how to control or where to put the Delete Command from my code.

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'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.
The problem is, when I open up the table by right clicking on it in the database explorer and selecting "Show table data", I click on the record I want to delete and the following error comes up in a message box[code]...

In the below code, it is supposed to load the data from the dataset, into the table, so that I can view and navigate the records.My problem is, that when the statement runs, it errors with:
System.Data.ConstraintException was unhandled "Failed to enable constraints. One or more rows contain values violating non-null, unique, or foreign-key constraints."
Here's the code:

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
z = 5

I'm using visual studio 2005 to develop a mobile application. The database i'm using is sql compact edition. I know in normal sql like mysql, ms sql i can do a multiple insert of data but in sql ce it don't work!
I know of a long way that is to just create a createVendor1, createVendor2 as many time as i need to insert the data..but i don't think this is the right way to do it. this is what i have currently, if i remove the 2nd insert , it works. NOTE: There is a semi colon at the end of the insert but that is not the problem as removing it also doesn't work.
Private Sub FormOrder_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
Dim createVendor As SqlCeCommand = connection.CreateCommand()
