DB/Reporting :: Adding A New Record To Access?
Apr 1, 2009
I just want to add a value from a textbox/variable and save it as a new record in a MS Access Database after a button click.
I've set up the database, set up the tables required.
From what I gather, I need to first link declare 'Imports System.Data' outside all the code. And also define a variable as a connection (Dim con As New OleDb.OleDbConnection) then access the database with "con.ConnectionString = "PROVIDER=Microsoft.Jet.OLEDB.4.0;Data Source = PathName").
What else do I need to include?

I have a self referenced table it contains Employee information, an employee reports to another employee, I've done this by including a field named ReportsTo as a foreign key that would be filled with the primary key. My first question is when using a strongly typed dataset how would I insert the first record without raising an error. the only solution that I could come up with is to insert an employee with the name NoOne and reports to himself i.e the employee number is the same as ReportsTo, this solution would be hardcoded in my program and only works when there is no records in the table. This is ok as long as I don't delete every employee from the table and try to insert new employees, in this case my insert will fail because the NoOne employee number is "1" and this would violate the index. this case calls for reseting the index each time I delete all the employees.

I have been following a tutorial in a book Vb 2005 Jumpstart Ch 4..Anyway I have followed the books code exactly and the program runs.It connects to Amazons web service and allows the user to search and display books, the application also allows the user to save the titles that they wish by clicking an Add Title button, when the user does this the current focus title is saved to the database and can be viewed off line.When I hit the add title the record gets saved as I can hit the catalog button which opens a new form with a datagrid that has all the titles I just saved in it!! But when I close the app and run it again the catalog is gone?? back to no records again?Now ive never worked with SQL databases before and this is me just having a go at .Net so I have no idea whats wrong or where to look.[code]

In an attempt to learn VB I'm trying to build a database project for a friend's business. This db will be used to track customer information, predominantly for targeted marketing purposes. So far, the development has been slow (I'm still trying to adapt from VBA to VB), but its all starting to make sense now. I'm using two different forms for adding new customers and reviewing the information of existing customers, mainly because the database will grow by about 2,500 customers per year and we wanted to be able to search the records without returning every record when the forms load. Most of this works so far, but I'm having trouble with two issues.
When I open the new customer entry form, I want the form to automatically begin entering data without clicking the "Add New" button. The second problem involves the row ID from the database. It keep showing up as "-1", "-2" etc. The row ID records properly in the table, so no big deal. I have read that this problem is a bug in VB and that its nothing to worry about. However, down the road I will need to access the correct row ID from this same form in order to print out a report for the customer (as needed).
For what its worth here is the code I have so far:
Code:
'Update current record when the form closes
Private Sub frmNewCustomer_FormClosing(ByVal sender As Object, ByVal e As System.Windows.Forms.FormClosingEventArgs) Handles Me.FormClosing
Me.TblCustomersBindingSource.EndEdit()
Me.TblCustomersTableAdapter.Update(Me.dsNewCustomer.tblCustomers)
[Code] .....

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've been having a problem adding a record to an Access database using datasets and da.update etc. I'm trying to create a simple program that displays the records of a database table in a series of text boxes. I've managed to get my next and previous buttons working correctly and my update button works correctly too. The problem occurs when I try to add a new record. I keep getting a "Syntax error in INSERT INTO statement" whenever I click my add button.

I have two tables Products and Categories with a many to many relationship. I am trying to copy the categories linked to one product (OriginalProduct) to another product (newProduct). The problem is when I execute the SaveChanges() method, I not only get the records in my linking table, but it also creates another copy of the categories in the categories table. I've tried this in many ways but here are the last couple that I've attempted:
' Copy Product/Categories
For Each oneProdCategory In OriginalProduct.Categories
Dim relatedCategory = _productContext.GetObjectByKey(New EntityKey ("ProductInfoEntities.Categories", "RecordId", oneProdCategory.RecordId))

I have a dataset; I want to create an equivalent record set. What I really want to do is create the XML that a record set can load; I have no other use for the record set per se. I want to be able to load recordsets on other machines (which use VB6 ins of vb.net) with this data. I found some code that loops through the columns in the dataset and creates the fields in the record set; that's executing. However, the code given to open the record set fails with "incompatible or incorrect parameters" or some such. [Code] I can see that a recordset is a construct meant to bridge between running code and a data store of some sort, but in this case the data is "stored" in the dataset, not anywhere else. I want to put that data in the XML form that the recordset uses, so that other code that can only use recordsets (ins of datasets) will be able to read it.

I am working with some DBF database files and have an interesting dilemma. I need to search through a table, find duplicates and delete them. Problem... Table doesnt contain a key.
So Table looks like this:
Name, BadgeNum
I need to be able to find instances like this:
John, 10
John, 10
and then delete just one iteration of John, 10.
Is this even possible? A "DELETE FROM TABLE WHERE BadgeNum=10" will delete both.....
