I added a table to my Access database. I added that table to my dataset. Using Database Designer VB Studio, my table and tableadapter show up in the design view.

View 3 RepliesI copy/paste one datagridview from one form to another (different solutions) using two instances of VS 2005.The target form has the datagridview with all settings, including the DataSet and tableAdapter used by the original form. The datagridview also has all old settings. Everything is fine, it works as expected, with one drawback: every time I make any change in the target form surface, VS tells me that the dataset and the tableadapter are not defined and no longer loads the form in design mode giving errors mention that the dataset and the tableadapter are not defined.To be able to view the form surface in Design Mode, I have to edit the form.Designer.vb file and replace the references to the dataset and tableadapter as follows

View 1 Replies[Code] my issue is that now i need two cases, first i need a query that will return the date created and modified of the table and i also need to know if its possible to query a list of table names in the database ordered by date created but that have a certain thing in their names. for example the database contains the following tables: [Code] and what i need the query to return is the tables that contain "Data", settings and employees are for the other functions of the program. so the query should return the 4 data tables in order of date created. but i have no idea how to go about doing that in the query, does anyone know how this is done?
View 6 RepliesTo get an id value after a table insert into an Access database you do a SELECT @@IDENTITY. I would like to know if this will work if your INSERT query is a table adapter query? I created an INSERT query for a table in the dataset designer which is working. My concern is that if I make another query with SELECT @@IDENTITY it won't work because table adapters make a new connection each time. Can someone clear me up on this?

View 1 RepliesI have a form that has a datagridview and a table adapter that displays data from a SQL database. What I'd like to do is that when edits are made to the data in the datagrid, I'd like to post all of the data back to the table. I know that you can do that with a dataset and a data adapter, but I don't know how to do that with a table adapter. Here is the code for my page:
Public Class ExceptionEdit
Private Sub ExceptionEdit_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
'TODO: This line of code loads data into the 'MDRDataSet.scratchpad3' table. You can move, or remove it, as needed.

When people click on the Save Exception button, I'd like to save back to the update the database with the new data.
I can do this easily with table adapter, but I can't seem to use variables in the table adapters connection string, or specify the connection string to use before "filling". Is there a way to populate the form without using any sort of binding? Currently I've used this method - a search form that populates a list box, and on the double click action I have this:
Private Sub lstResults_CellMouseDoubleClick(ByVal sender As Object, ByVal e As System.Windows.Forms.DataGridViewCellMouseEventArgs) Handles lstResults.CellMouseDoubleClick
'Fills Main Form
Dim firstcellvalue As String = lstResults.Rows(e.RowIndex).Cells(0).Value.ToString()
frm_IMT.intPendingID = CInt(lstResults.Rows(e.RowIndex).Cells(0).Value.ToString())
frm_IMT.Show()
Then When the form loads:
Me.PendingTableAdapter.Fill(Me.Phone_memo_backendDataSet.Tables("Pending"), intPendingID)
