I'm trying to insert data onto a SQL server database. The Database connects up fine and retrieves data but I'm having difficulty inserting new data. [code] The query works if I run it through the table in database explorer and value of dim h shows 1 (rows affected). However, nothing gets updated.

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 trouble inserting values into my Account table that's in a SQL Server Compact Edition database. I keep on getting an error that states [code]....
I am not sure if this should be in the SQL or vb.net section.But, Basically I have a vb.net application from where I insert a datetime field into the SQL Server Database. Now for some reason the SQL server field(which is datetime) will not display AM/PM, I have referred this link where my code looks like this:
Dim dateToDisplay As DateTime = DateTime.Now dsNewRow.Item("date_created") = dateToDisplay.ToString("MM.dd.yyyy hh:mm:ss tt")
I tried stepping into the code by debugging and it seems to be inserting the PM but is not displayed in the table QuotedateToDisplay#8/12/2011 6:01:06 PM#Date

I am using VB.NET 2010 and SQL Sever CE 3.5 database. I insert some data into my database (SDF file) and I can do any all manipulations with those data. But I cannot see those data in the data table using Data Source or Server Explorer in Visual Studio. Even If I check it once in Server Explorer, all data in the database will be deleted.
I have a VB.net app (which I will turn into a webform soon), my app generates a datatable of values (3 columns and on average about 1000-3000 rows).What is the best way to get this data table into an SQL Server? I can create a table on SQL Server no problem but I've found simply looping through the datatable and doing 1000-3000 insert statements is slow (a few seconds). I'd like to make this as streamlined as possible so was wondering is there is a native way to insert all records in a batch via ADO.net or something.
In my SQL Server database I created a Table called "QUESTION" with the same fields. QuestionNumber is defined as integer unique key, auto increment
Now, when i make a bulk copy to insert the DataTable into the SQL Server, the database overwrites my QuestionNumber from the DataTable and generates new ones (starting from 1 increment 1).
How do i have to change my database setup, that the original QuestionNumbers are copied into the database?
I just re did my question and added a few other scripts needed to pull everything together This is the small script I am using to receive the post and push the data into the SQL Server (2008 if that matters):
when i try to insert data from database into dataset using data adapter, it takes long time, i want to use hourglass but i'm confused how or when i type the code so user will know that application still work.
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()
Dim myConn As SqlConnection Dim cmd As SqlCommand Dim sqlstring, DNAME, DEXP, DCREATION, DLASTUPDATE, DCOMMENTS As String
[code]....
When I execute, it gives me this error:Cannot open database "DOMAIN_NAME" requested by the login. The login failed.Login failed for user 'comm-pc10pcuser10.comm'.and it highlights myConn.Open() I have SQLServer 2008 and a user name and pass for my database.
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 verified data types that are being inserted to insure that this is my problem. I dont see any exception errors.Am i missing a veriable or something that is related to my connection.
