I'm creating another database searcher, only this one is a little better user friendly than the one I made with a datagridview. I'm using the "details" of my dataset(CustomersDataSet) and trying to add a record into an existing database. I'm using this code
Me.TableAdapterManager.UpdateAll(Me.DatabaseDataSet)
which worked for me when using the datagridview, but for some reason it won't work now. Even when I check for my test "add a customer" in the access database itself, it isn't added.

I want to throw exception if user tries to insert same record having same CourseID and CPUserID.
i've added new item called service- based database. after that, i've created doctor table, course table, exam table, and an empty table called exam_report to allow program selects randomly from the other tables.
how it works: first the user will get a form with many buttons: courses, doctors, exams, and exam report. second if the user click over exam report, a new form will appear with many columns. this form should has exam course - exam day - exam time - 3 doctors name who will observe the students.
behind code: the doctors shouldn't be the instructors of the course - the doctor has no appoinment in this day - the doctor has no hloiday and so on..
okay my code is the following :
Public Class Form6
Dim j, a As Integer
Dim d, f, h As Integer

Now i want to update the existing record which has been populated from the gridviw of the paxsearchfrm and also want to have the option to delete the record.I am using the datacontrols(wizard) to make connection with the access2007 database.can someone give me some example of how to do the Edit and delete in the database pls.I already have a save button on the paxreportfrm(if i click on that, after changing the details on existing record, it just saves IT as a new record).so i really need something which will actually save the modifications on the existing record AND ALSO WILL BE ABLE TO DELETE IT FROM THE database. I have tried couple of methods but none of them are working.

For some reason my code is executing the INSERT query twice and putting duplicate records in my table. If I put a primary key on one of the fields I get a runtime error and it complains about the fact it can't add the record twice.The part of the code that INSERTs is near the bottom, bolded and italicized.

I am creating some basic software for our manufacturing department. I am using Visual Studio 2008 using Visual Basic.The software has a user log in. There is a form in which the choose the worker name, the item they were making, how many were made, damaged, or received damaged from the supplierHowever when they click on the "Update" button to insert the record..i get my custom message that it failed and the record is not inserted.
