View 1 RepliesI am working with VB.NET.. i have a DataTable called "QUESTION", containing 3 fields:
QuestionNumber (unique integer key)
QuestionText
QuestionType
In my SQL Server database I created a Table called "QUESTION" with the same fields.
QuestionNumber is defined as integer unique key, auto increment
Now, when i make a bulk copy to insert the DataTable into the SQL Server, the database overwrites my QuestionNumber from the DataTable and generates new ones (starting from 1 increment 1).
How do i have to change my database setup, that the original QuestionNumbers are copied into the database?

The system should not insert selected records from my datagridviewcheckboxcolumn if it's already existed in the database.It's like when you're registering online. If you're username/email address already registered,it would inform you that youre username/email is already registered and the site would ask you to change your username/email to new ones.The difference in my system is that i have 2 datagridviewcheckbox columns not just textboxes . Parent and Child in the datagridview. What i want to happen is that once the Code has been registered as Parent it cant be registered again as Child anymore.

View 3 Replieshow to update records on an existing access database using vb.net with just a textbox and a command button and how a specific record of a field can show up in a label or a textbox
i connected vb.net to my access database by just clicking on "add new data source">>"new connection">>"microsoft access database file" and just continue..tested connection and done.
you can see in the screenshot of my form, by default the left side textboxes are disabled but they're enabled if the user checks the checkboxes and disabled again if unchecked.
assuming that the textbox is already enabled and i want to enter a value in the Brewed Coffee area of the form...for example 5. when i click on my Submit button the value of that particular record in the database will be updated, so in my table the value of the quantity field in Brewed Coffee will be 5.
another thing is that how can i see a particular value on a label or textbox from my database like on the Prices area. in my database if a product's price is 80 then it should show a 80 in the label. the values of the prices from the screesnshot of the form are not the ones on the database xD i just typed them in.
