Im Trying to insert the values of the datagridview into my table but im having some problems i keep getting the error "Object reference not set to an instance of an object"... need this urgently.. heres my code:
For i As Integer = 0 To DataGridView1.RowCount - 1
DataGridView1.Rows(i).Cells(4).Value = CInt(DataGridView1.Rows(i).Cells(2).Value) * CInt(DataGridView1.Rows(i).Cells(3).Value)
[code].....
How will I insert the output of my DataGridView to another table in the database? I have 4 Columns. The First and Second Columns are Check Boxes. The Third is The Stockholder Code. The Forth is The Stockholder Name. What I want to happen is, my selected records(The Stockholder Code, The Stockholder Name ) via check boxes will be inserted in my database.
Here's what I've done so far:
Try
For Each row As DataGridViewRow In DataGridView1.Rows
Dim cell As DataGridViewCheckBoxCell = CType(row.Cells("checkboxchild"), DataGridViewCheckBoxCell)
[Code].....

The problem, The INSERT statement works fine in the form load but not in the button click event?
Im getting an error with my insert statment "Syntax Error in INSERT INTO statement". I do not understand why. Im using global variables from form 1 and using them in form2 and trying to insert them from form2 into the database.

here is my code so far:
Public Sub cmdSave_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles cmdSave.Click
Dim i As Integer
[Code].....
when i click the button, i get a error message saying "Syntax error in INSERT INTO statement". as far as i can tell, i have everything i need to insert a new row into the database, and i dont see why this problem is occuring.
item(0) is an autonumber key field, so that should make a new record by itself, and i have declared the input textboxes as the data() array
I am using Visual Studio 2008 and have connected a database correctly as I have done a login that works fine, although when I try to insert information submitted in the text boxes a different table, it doesn't enter after I end program to check it still has no data in.
Dim con As SqlCeConnection = New SqlCeConnection("Data Source=NESdb.sdf")
Dim myDA As SqlCeDataAdapter
Dim myDataSet As DataSet

I am having a critical problem in using Insert Into Statement.I made a small program with Two Textboxes 1. txtName 2. txtRollNoWhen I Enter any data in these fields, the Programs runs fine

I am receiving syntax error in my insert into statement when I try to use try and catch phrase. The highlighted one is the cmd.ExecuteNonQuery() . What seems to be the problem in my code? I'm using autonumber for the ID so I won't put it manually. I am able to insert records when I don't use auto numbering but I need it so don't have a choice. For my database, I only have 3 fields which are AdminID, Username, Password.

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.

Using a sqlcommand is it possible to use subqueries in an INSERT statement? I attempted the following (and numerous variations playing around with syntax):-
Using insertuser As New SqlCommand("INSERT INTO Users (UserID, Name, Password, Phone) " _
+ "VALUES((Select MAX(UserId)+1 as UserId FROM Users), @name, @password, @phone)", conn)
Errors with 1046: Subqueries are not allowed in this contect. Only scalar expressions are allowed. The scenrio is the userID is hidden from the user and does not appear on the form, I want to find the last value (MAX) userId (integer) and increment by 1. Errorcode 1046 suggests I can't but was wondering if it can be done but was going the wrong way about it.
