I add a new record into my access table using.
Dim comm As New OleDbCommand("INSERT INTO SaleInfo VALUES ('" & ListBox1.Text & "', '" & TextBox1.Text & "', '" & TextBox2.Text & "')", Con)

How can you add a new row at a certain index in the table?
I've got the web browser with tabs in all working fine, but there's one bug, i can add tabs, delete em, etc.. but when i delete a tab then go to create a new tab, it gives me the error: InvalidArgument=Value of '6' is not valid for 'index'. Parameter name: index '6' is the number of tabs i had open.Here's the bit of code i use to create the tabs with the browser in it:
vbcode
Dim browse As New WebBrowser
browse.Name = "b1"
browse.Dock = DockStyle.Fill
[code]....
When the selected index changes I for a second time this code errors.
vb.net
lvReports.SelectedItems.Item(0).SubItems.Item(2).Text
with this error message
InvalidArgument=Value of '0' is not valid for 'index'. Parameter name: index
Why is this?It worked for the listviews.click event perfectly.
I want to create an index on my table. I used the following command Code:
cn = New OleDbConnection("Provider=Microsoft.Jet.OLEDB.4.0;Data Source=D:database.mdb;Persist Security Info=False")
cn.Open()
cmd = New OleDbCommand("Create INDEX itmno_idx ON INVENT (ITEM_NO)", cn)
cmd.ExecuteNonQuery()
Now I want to use this. Is there a file created with some extension when i do an Indexing?. Is the above statment actually index the field, ITEM_NO or do i have to use ALTER TABLE command? Currently I am getting error "Cannot execute data definition statements on linked data sources"

I have a foxpro table <b> INVENT.DBF</b> linked in MS ACCESS. When I tried to do a search in the table from vb.net application, it is taking a long time. So I want to index the foxpro table and then use it for search.
Here is the sample code I wrote in vb.net <i>
cn = New OleDbConnection("Provider=Microsoft.Jet.OLEDB.4.0;Data Source=D:database.mdb;Persist Security Info=False")
cn.open()
cmd = New OleDbCommand("Create INDEX itmno_idx ON INVENT(ITEM_NO) ", cn)
cmd.ExecuteNonQuery()</i>
But I am getting error "Cannot execute data definition statements on linked data sources"
What needs to be done to index a linked foxpro table using VB.NET.
I'm, using a SQL Server table in a DataGridView and I'm having trouble adding records. I'm new to vb.net but used vb6 for a lot of years so the transition is a little difficult. For now I'm just trying to add a record using a button click but the record key which is setup as integer and to automatically increment by 1 shows as -1 after the record is created. While the data does show in the grid it is never actually posted in the table. Once created I want to select the record just entered.
Here's what I have:
' Declare
Private addedRowIndex As Integer
Code:
Dim newMessagesRow As ArcadeDataSet.messagesRow
newMessagesRow = ArcadeDataSet.messages.NewmessagesRow
newMessagesRow.movie_title = "Added Programmatically"

View 2 RepliesI am an old VB2 programmer and in the process of moving up. In VB2 I could obtain a data row via and index on an access table. I can not find an example on how to do this. I can retrieve a single row using a query, but an index would be faster. I know in Oracle use can use a hirt to direct the query to use the index.Here is what I was during in VB2 (Sample) with no hint.

I am coding a program for a movie trivia game that randomly shows a movie quote and the the user selects a movie name from a combo box that matches. I used a array for the movie quotes and a comboBox for the movie names. I have coded a portion of the program but I am stuck on how to compare the array quote being shown to what movie the user selects from the comboBox. I have tried numerous different things but none seem to work right. The way I have it coded now it shows that every movie I pick that it is right even if it is wrong. I am going to show part of the code here and also attach the entire solution for anyone that needs it .
