Vb net code for updating access database
I believe the dataset.clear() method clears the whole dataset, is there something like a datatable.clear()?
Many examples demonstrate how to use parameters to insert variables. I renamed all my fields in the database and in my code to mmddyy and it started working, well sort of...is writing to the database now but it is not filling the database with the information from the form, instead all my fields say either: "System.

Add With Key Dim table As New Data Table 'Retrieve the data. New Row() row("Date") = mmddyy row("Driver") = Driver row("Truck") = Truck row("Customer") = Customer row("Rate") = Rate row("Where_From") = Where_From row("Where_To") = Where_To row("Pit_Ticket") = Pit_Ticket row("PO_Number") = Po_Number row("Yards_Tons") = Yards_Tons row("Description") = Description row("QP_Fee") = QP_Fee row("Fuel") = Fuel row("Expenses") = Expenses row("Advances") = Advances table. Ole Db Data Adapter("SELECT ID, Date, Driver, Truck, Customer, Rate, Where_From, Where_To, Pit_Ticket, PO_Number, Yards_Tons, Description, QP_Fee, Fuel, Expenses, Advances FROM Shenandoahs", connection) Dim insert As New Ole Db.
OLEDB.12.0; Data Source='C:\Users\Richard Colbert\Documents\Visual Studio 2008\Projects\Windows Application1\Windows Application1\shenandoah.accdb'") Dim adapter As New Ole Db.
Please don't clutter up Codebank threads with every question you may have that's remotely related to the topic.
And what would be the syntax for clearing a specific datatable, if there is such a method in .net?
Understanding what's above should help you understand how Table Adapters work internally though.

Additional Info: in the first scenario, im going to create a new data, and because this is a Time keeping System, First Im just going to get the Time IN and leave the Time OUT Column blank..

EDIT: Note that I have updated the code examples slightly in this post and post #3 to more accurately reflect real usage situations, particularly using a Data Adapter to get and save data in separate methods rather than in the same method. This situation is much like the fourth example above, except you don't need to retrieve any data to start with and you obviously don't need the Update Command and Delete Command: I should also point out that you don't actually need the Select Command and the Fill Schema call either. (This is my first post.) Still i would request a good class/module for db connection in access. I m trying to work in i have done little programmings in vb6 and 05. what i want to do is i want to retrive this recordset and update the Time OUT column. Table: TIME_IN_OUT Emp No Time IN Time OUT 00001 AM N/AThis thread already shows you how to retrieve the data from the database and save it back again.
There is all sorts of literature on this topic but people still keep asking the same questions. If you're not using SQL Server then it's a simple matter of switching to the corresponding types of the appropriate namespace for your data source. It can be used to execute a query but you'd never use it for that unless you were populating a view or temp table. Finally, this code uses all the "old style" data access types. NET 2.0 I suggest creating a Data Source to generate a typed Data Set and Table Adapters.
