I am working on code in Visual Basic 2010 that will read from an Access 2007 data table. If the row has one of the fields marked as processed then do nothing with it, but it not, then process the data in that record, and update the field as processed, and move on to the next one marked as needing processing, looping through all of them. Later I'll go back and repeat this again.
I am able to read from the database and get all the information from it just fine, but I can't then update the 'processed' field. I'd rather like to avoid having the database integrated with the project as other processes will need to access it when this process (program) is not working on it.

I am using this code to Add rows to a SQL database, and it adds the row to the SQL database if column 7 is not null. After it adds the row to the SQL database, it deletes it from the Access Dataset, and updates the Access Database. Sometimes double rows seem to get inserted into the database, so I'm thinking there is an error in my logic somewhere here.
Dim rowcount As Integer = AccessDataSet.AccessTbl.Rows.Count
Dim y As Integer = 0
For x = 0 To rowcount - 1
txtRow = AccessDataSet.AccessTbl(y)
If IsDBNull(txtRow(7)) = False Then

I'm writing a program for Employees Management and i need to automatically generate a Payroll for each one then calculate some things and save it to another table.

For a project i am working on, i am taking bookings. These bookings are stored in a database alongside a users personal details. The personal details are assigned an ID according to the user who booked it. A user can book more than once with different personal details.
My problem is that i want a user to be able to edit a booking. I want a list of all the names that user booked to be listed in a combo box. This is the part i am having trouble with. i am using an access database and using sql statements to pull out the data. This is what i have tried so far:
SELECT [First Name]
FROM PersonalDetails
GROUP BY [First Name], UserID
HAVING (UserID = ?)
If i execute this query in the query editor, it works and shows the two records currently assigned the input id. However, if i try to output this to, for example, a text box, then it remains blank. I am assuming thisis because there is more than one output, but i'm not sure.

I am trying to create a sign in program for my members. They come to the computer, input their birthday (already in the database), and up pops a Form with DataGrid that shows all the members with that birthday. Here is where im getting stuck. I want the user to select their name (row) from the DataGrid, click the button Sign In, and have the database be updated in the "Attendances" column to previous+1.
I first approached using the DataGrid1.SelectedRows.CopyTo method but had no luck. If someone could please help me to read which row the user selected, and then search the database for that persons name (which the row contains), and add 1 to a column in the database.

Any method that can effectively get the total number of rows that is StartRows to EndRows in a database table and then get the corresponding data from that row as currently I am having difficulty in retrieving out the correct row of data to the column that I am comparing. It will always get the first row of data regardless of which row I put in the handphone number which I'm comparing to. The codes below is the one which I am currently using now to detect the maxrows in the database and also to retrieve the corresponding information.
MaxRows = ds2.Tables("CustDetail").Rows.Count
MaxRows = MaxRows - 1
Dim numbers() As Integer
Dim EndAt As Integer
inc = 0
[Code] .....
I used a msgbox(n) to see the number of rows in the database but it displays only one where I have two rows in my database. The for loop is the one which will detect the number of maxrows and also retrieve out the corresponding details. But apparently this is not the appropriate way.
I've created a Point of Sale program using Access and VB.net. I have an Inventory table from which items are sold. There is a quantity column and I want to be able to reduce the quantity for any item by the quantity that was sold in the point of sale front end. For example, there are 5 bracelets in inventory and 1 is sold. The quantity is typed into a textbox. The inventory quantity should now be 4 in Access. I don't know how to make this happen from the point of sale screen.

I am trying to append multiple rows in a SQL Server.I have connected to the MS SQL Server and with a DataAdapter, I have downloaded the Table into a DataTable and displayed it in DataGridView.I now want to programatically enter multiple rows into the DataTable and later to update the SQL Table.
I am trying to build an application to do this generically.The problem I have is that the Table and DataTable has an 'ID' Field. In the SQL DB, i is an Auto-incrementing field.When the code loops through creating new rows and entering field values, how do I handle the ID Field that is the Primary Key?

I'm working on a project and my boss insists I use a DataGrid for this. The grid holds information for work orders, one of the cols has a check box in it. I need the user to be able to select any number of those checkboxes/rows and then return a value to the table "stamping" that users ID. This is what I have so far to get the grids populated... I'm using 2005 with a 2000 Access Database if that helps. Though this will be changed to SQL Server once we get it working (yay more work)...
[code]...
I removed the code from the second grid to make it easier to read, obviously once I can get one to work the second shouldn't be as much trouble.
This is the check box: dgvNewBiz.Columns(1).HeaderText = "Select"At this point if someone knows how to get it to recognize the click event of the check box and pass that row info to a variable that would be super as I'm sure I could probably figure it out from there.
