I have a SQL database names TestSQLVB
In it a table called tblTest2, with a three fieldstest2id , int, pk, increment by 1field1, varchar(50)field2, varchar(50)
I have a dataset named Dataset2.xsd
A tableadapter named tblTest2TableAdapter
A insert query names InsertTest2 with fields @f1, @f2 and ExecuteMode = Scalar
When I run the following code per MSDN [URL] the database does not get updated.

When you are working with a database, is it then possible to make the program save stuff, so when you close and open the program, it could etc. save a text in a textbox?
I have a form that contains a Textbox + Three sets of radiobuttons.
my project idea is to store in any database the values selected or entered by the user.
Textbox goes Name.
First set of radiobuttons are the job position - manager - superviser etc.... Second set "" "" the Period (Shift)- day - nite Third set "" "" The Condition - part-time - full-time
Anyway, my problem is how to insert those values into a database, something very simple such as MSAccess (is possible?)
Okay, I've made a local database now and everything is okay. But I don't want the normal data grid view, I want to display the information in a list view. How can I do that? Do I have to make some sql queries or something?
I have made a small form where I have bound textbox with records from database.Although my code for inserting and updating the record seems fine and working. But when I view the database, tables i see no inserts/updates made there. But When I run my application again, I see the records in the bound textbox but only for some seconds (for around 1 and half minutes), although they are not shown in the database (tables) actually.
When I close the application and run again it after 1-2 minutes there are no more records bound to the textbox, since no records at all.How can this be possible. I don't have any idea what's going on.
I have been using visual studio 2008 and sql server.Code I have been using for ::
'Update the Records Private Sub btnUpdate_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnUpdate.Click

I need to import data from Excel into a MySQL 5 database. The format of the column in excel is set to "Time". the field value looks something like this:
17:20:00 If I do this in my vb.net
strTimeIn1 = Trim(jobdt.Rows(j).Item(7).ToString)
I get this in my Immediate window when debugging:
"12/30/1899 4:10:00 PM"
what's the correct way to convert that string to a time value so I can insert into a datetime field in my database with no issues.
I'm quite new into the programming game, I've been working on this program for a few weeks now, and its coming along, but the method I searched for entering new rows of data into my table doesn't seem to update my tables after I try entering data. I have a feeling it may be something very simple that i am over looking.

I am using this code to Add rows to a SQL database, and it adds the row to the SQL database if column 7 is not null. After it adds the row to the SQL database, it deletes it from the Access Dataset, and updates the Access Database. Sometimes double rows seem to get inserted into the database, so I'm thinking there is an error in my logic somewhere here.
Dim rowcount As Integer = AccessDataSet.AccessTbl.Rows.Count Dim y As Integer = 0 For x = 0 To rowcount - 1 txtRow = AccessDataSet.AccessTbl(y) If IsDBNull(txtRow(7)) = False Then [Code] .....
I am looking at Visual Basic 2008 Step By Step. I need to read a flat file and insert the records into my SQL database. My code so far:

The INPUT line needs to be fixed. From what I can see, I need to move it all to a single field and use a split to parse it, correct? As I look at the entries on this site, all the code seems to use stream readers. Why would the book not do that? Am I missing something?
the codes run with no errors, but the data is not save in the sql server table event though the codes run.Dim connection As New SqlClient.SqlConnection
connection.ConnectionString = ("Data Source=.\SQLEXPRESS;AttachDbFilename=|DataDirectory|\DB.mdf;Integrated Security=True;User Instance=True") connection.Open() Dim command As New SqlClient.SqlCommand command.CommandText = "INSERT INTO [studentsummary] (sum1,sum2) VALUES (@sum1,@sum2)" command.Connection = connection
I am creating a feature in my application that will allow a logged in user to add additional users to be logged in. The usernames and passwords are kept in a single database created in Access 2007. The table has 3 columns: ID, UserName, and Password. I am trying to insert user-inputted data through a TableAdapter function in a DataSet. It has worked once but for some reason it stopped working, and I can't figure out why.
Calling the TableAdapter function... Me.UsersTableAdapter1.AddUser(Me.txtID.Text, Me.txtUsername.Text, Me.txtPassword.Text)
[Code].....
Visual Studio isn't throwing any errors my way or anything so I am not sure what's going on here. The fact that the code worked once but isn't working now is also confusing, and I don't recall making any changes related to this feature since it worked that one time.

I'm running into a slight problem with an SQL INSERT INTO statement. I've tried setting this up first as a command statement and now as a stored procedure. When the process runs it's not signaling any errors and it appears that it's working properly. However when I check the database nothing new has been added. I have the statement within a try catch and it's not catching any errors. I've gone so far as to delete the table and recreate it, still nothing. I should also point out that this entire statement was essentially a copy & paste from another program that's working perfectly.
vb.net code below
Code: Try Dim cmd As New SqlCommand cmd.Connection = con
