Feb 24, 2012
Situation Overview I'm using Ext.NET GridPanel to display a list of projects which has tasks (i call it Sprints) inside it assigned to some user and a status. So I get this kind of relation:

ByVal e As DataGridViewCellEventArgs) _
Handles DataGridView14.CellEnter

I only want specific columns to show up in my DataGridView, so I run a dynamic sql query to select specific columns from a table on a sql server(I know its slow, but its only used once a day). However, every column from the table shows up in the datagrid, and I can't figure out what i'm doing wrong.
Public Class Assign_Priorities
Dim connect As New SqlConnection("Data Source=IRNTS4SQL;Initial Catalog=Materials;Integrated Security=True")
Dim ds As New DataSet
Dim da As New SqlDataAdapter("SELECT [Priority], [Tool Type], [Lot Number], [Process], [Priority Notes], [Quantity], [Time Job Entry] from [FPAD Process Log]", connect)

I need to get a table on my Form that has different columns from differen tables.As I call many tables by their Identity ID, I also need a way to show the information from that table.I created a query in my TableAdapter which selects information from 2 different tables. Tested it in the query builder and all was OK.I tried to put an empty DataGridView onto my Form and inserted the correct BindingSource for my Data Source.I then added a query and selected the query I created in my TableAdapter.

My goal is to connect to my database either manually or using an sqladapater, and get information from two of my databases on sql server 2005. Then I want to take this information and on run-time begin to add/subtract/divide/multiply certain columns and place the information into other columns. I can do this in queries, however, I want to do it on run-time what is the best way to achieve this.I had some of this working, but I just want to start fresh and see how you would go about doing this.

I am using the following code to alter an table imported from an Excel spreadsheet
Dim SQL As String = "ALTER TABLE receipts ADD payee integer, account integer, category integer, reconciled boolean"
Dim dataread As New OleDb.OleDbCommand()
dataread.Connection = Connection1

Both ExecuteNonQuery() actions yields the exception message {"Syntax error in field definition."}The error message does not happen with the first if the boolean column is not there (I tried Tes/No as a definition - but that also failed.The second query to modify the ID column from autonumber to integer I assume fails because it is a Primary KeyHas?

SQL statements:
SQL = "SHOW TABLES;"
Try
conn.Open()
The remarked area works fine when I'm accessing a specific table. I've successfully inserted the products_model field into the combobox too. The datagridview does show the table names in the db using the SHOW TABLES sql statment, but I'm not understanding how to get this info into the combobox instead.

I have a datatable property called prpParametersTable in a class called clsBatch. I have a procedure that sets a datatable variable called dtP equal to prpParametersTable at the beginning of the procedure. I then add three new columns to dtP.Here is my problem. When I add the three new columns to dtP my original table prpParametersTable also gets those columns added to it, why? I only want to add the three columns to dtP and not prpParametersTable. How can I do that?
Private Function prvfnc_InsertBatchParameters(ByRef cnn As SqlConnection, ByRef trans As SqlTransaction) As String
' set new columns that have BatchID, Insert DateTime, and UserID for the SQLBulkCopy method below
Dim clm As DataColumn
Dim dtP As DataTable = clsBatch.prpParametersTable
