I am looking for the simplest way to push a new row to a database by inserting one record and then retrieving the Primary Key generated by inserting that row.
I know there are several ways this can be done but I can't seem to get any of them to work yet.
I have made a form that has three labels and textboxs and two buttons. The labels arelblPersonID, lblFirstName and lblLastname. The textboxs are txbPersoonID, txbFirstName and txbLastName. The two buttons are btnSave and btnQuit with "End" in htis button. I have also made a database "MyFriends" with a table that has PersonId, FirstName and LastName.
I want to be able to type into my textboxs and have that information saved as a neww row.

I have a project I created for my VB class where you enter what type of ticket(combobox), how many tickets(textbox), what type of tickets(listbox) and will give you the total amount.I want to do a little more to the program and was wondering about adding the person's name, address, phone, city, state, zip and then having all the information put into a database. I wanted to also take the information entered from the program and use the printPreview control to view a report from Access(possible?).
I've only worked with viewing database information on the forms in VB but I've never entered data into the database. Is this possible?Can I have the information entered on the form be entered into a database that keeps track of all tickets purchased and customer information?I can see this working in my head but don't know if it's logistically possible.

View 13 RepliesMy program has an access database with a table called "Contacts". This table stores many values. I have a seperate table that stores surveys. Each contact should have a column for every survey, indicating whether or not the survey has been completed. However, this means I need to add columns to the database while the program is running. I tried the following code, which runs WITHOUT errors, but does not seem to actually add the column.
contactsDataAdapter = New OleDb.OleDbDataAdapter("SELECT * FROM Contacts", frmAdmin.con)
contactsCommandBuilder = New OleDb.OleDbCommandBuilder(contactsDataAdapter)
dtContacts.Clear()

I'm at another wall in my project. I've been trying to get it to add a new record to a table but I got a message that said "Object reference not set to an instance of an object" but I have no clue where the error is popping up. I am also unsure of whether the coding for adding a record will actually work on not.Here is the code for the form with the bits subs that I'm sure aren't the problem removed (as they have no relevance to adding a record);

We're trying to work out some code for saving from a textbox to a database field without using DataGridViiew. We have it working using the automated controls that Visual Studio gives us, but if we have a form with text boxes, can we make it so that, on a button click, it dumps that stuff into a field in a table?

I'm new to databasing. How do you make it so you can add an item to a database on a form, Then follow a link to another form which has the database on, then what you put in on the previous form will be there?
How's it done? Sorry - Haven't been using VB very long >.<
