I have a system that I need to connect to an access database. Once connected, I have a form that allows a new customer to be entered into text boxes. I need to then take the data in the text boxes and save them in the database table.On a similar note, I have another form, where the customer details can be updated. Basically, by searching for a Customer reference number in the database, the form is populated with the table data. Then I want a button that will update/overwrite any chages made.
I have made DataGridView in the designers and connected an Access database to the datagridvies and the Column headers appear as they should and when I check in preview mode all the fields are correctly populated. However, the DataGrid is not populated in normal mode at all. I have been trying to run the project but nothing is happening. What can I do to populate the field.

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)

I'm writing an asp.net page with a simple registration form that connects to my access database and inserts the values in the table.

I am trying to populate my combobox from Access, I decided to use a function in a separate module to connect, querry and return the result to my combobox for the sake of diminishing the number of lines, but I can't get it to work in .net.
Here is the module I modified from what I found on the net: Module DataModule Dim cnn As Data.OleDb.OleDbConnection = Nothing Dim DBpath As String = My.Settings.SDBPATH Dim SQLString As String Private cnnOpen As Boolean = False [Code] .....
I remember .eof method for my "While Not" loop but I can't seem to make it work. Basically the table in my DB consist of 2 columns, the first being ID (autonumbers) and the second are the records I want to access via my combobox, there is about 10 rows for now but it is subject to change.
I have created the code to take the input of excel but i don't have any idea how to go ahead. Supposing my excel has only 1 sheet with huge amount of data, and i want to upgrade my Access database everyday using excel sheet then how to do it?[code]...
I have an accdb named base.accdb in the root folder of the program. Basically I have several tables in my database and I need to show their values in listboxes (essentially allowing menus to be edited by adding/removing items in the table)I can't figure out how to connect the database (according to my friends/classmates), and i can't figure out how to pull the information from the table.
Ultimately, it would be nice if someone could tell me how I can pull out the information into maybe an array? so that if i add 3 items into the table, then it will create 3 variables in the program and put the values from the table into those variables.
I am using VB and have created a Access Table with a few columns. Simple things like....user name, password, etc. I created this table for my login form. I just want a simple login form where the user enters their user name and password. Then it is checked to see if it matches the Access Table. If so they are allowed in if not prompt and error message. For starters: I have the table created (it will only need apx. a dozen user names/passwords) I have the data source linked to the form already. My realy problem is getting the User validation information to compare with the access table accurrately. The Access Table is linked and the first row of the table is arleady in the text boxes. So, I went ahead and replaced them with noting on the form load.
That's the code I am using. It is not working. It either lets you in no matter what as long as there is data in each text box or it will not let you in even if your data exactly matches. I am trying to get the first instance to work before I try to get all the login names and passwords to work.
I have a form with a list that shows information from a database. I want the list the update in run time (or almost real time) every time something changes in the database. These are the three ways I can think of to accomplish this:Set up a timer on the client to check every few seconds: I know how to do this now, but it would involve making and closing a new connection to the database hundreds of times an hour, regardless of whether there was any change Build something sort of like a TCP/IP chat server, and every time a program updates the database it would also send a message to the TCP/IP server, which in turn would send a message to the client's form: I have no idea how to do this right now Create a web service that returns the date and time of when the last time the table was changed, and the client would compare that time to the last time the client updated: I could figure out how to build a web service, but I don't how to do this without making a connection to the database anyway The second option doesn't seem like it would be very reliable, and the first seems like it would consume more resources than necessary. Is there some way to tell the client every time there is a change in the database without making a connection every few seconds, or is it not that big of a deal to make that many connections to a database?
I am trying to learn how I can enter data into a Microsoft Visual Basic 2010 TextBox on a form and when I Tab to the next TextBox, the data from the first TextBox is automatically appended to a Microsoft Access 2007 table. For this question, no other controls or objects are necessary.

I have a table called MEMBER with fields for mem_id, mem_name, mem_addr, mem_city,mem_state, mem_zip and another table called STATE with state_id, state_addr, state_name in Access 2007.On the Visual Studio 2008 form, there is a combo box for the state. The goal here is to display the state abbreviations, but use the state_id value for the mem_state (there is a foreign key between those two fields).The mem_state is defined as number, the state_id is autonumber. Under the mem_state definition in Access, I used the lookup wizard (on the database that is in the bin/debug folder) to set the following properties:
Display Control - combo box, Row Source Type - Table/Query, Row Source - SELECT [State].[state_id], [State].[state_abbr] FROM State ORDER BY
