View 1 RepliesI had to add another table into my database and now I need to go back and update a page that allows inserts into more than one table. I didn't write this page, so I'm trying to clean everything up, but there are some parts that I don't really understand. Now I have broken the page and it only inserts into one table. The very first one that I insert into.ProductName: goes into the Product table.Description: goes into the Picklist table as Data.....it also is supposed to generate an insert into the marketing table based on the PicklistID which is an identity column. The marketing table tells the Picklist table that it is looking for a description. [code]
Like I said before, only the insert that goes into the Product table works. Before I added the Picklist table and tried to reconnect everything, this entire page worked. The code was a lot sloppier and didn't have parameters, so that could also be where I messed up since I am still trying to learn how to use them. I have gotten everything to INSERT except for the INSERT to the Marketing table.
I've got a form where a user enters data. When the user submits that data, it inserts a record to two separate tables via a dataset. One of the records has no problem being saved into the database (in the table it was put into), but the other record seems to temporarily be in there (according to a third form), because it exists for the duration of the application, but when I exit, and then check the database, it's not there, and it's not shown on the third form when I restart the application again either.
View 11 RepliesI need to get a table on my Form that has different columns from differen tables.As I call many tables by their Identity ID, I also need a way to show the information from that table.I created a query in my TableAdapter which selects information from 2 different tables. Tested it in the query builder and all was OK.I tried to put an empty DataGridView onto my Form and inserted the correct BindingSource for my Data Source.I then added a query and selected the query I created in my TableAdapter.

This is how I do now

There is a "how do I video" on how to properly control updates, inserts and deletes in multi-user applications on forms that edit master-detail related data. [URL] Massi worked through the process using Order (OrderID is PK) as the master table and Order Detail (OrderDetaiID is PK) as a related table in dataGridView. The dataGridView automatically generate orderDetailID whenever the mouse enters in a new row. I am doing a similar form, but placing order form and orderDetail form in two separate tabs in a tabcontrol, and also using Details view for both tables. When I click "new" button in BindingNavigator, the orderID is automatically generated. If I use dataGridView for my orderDetail tab, then the orderDetailID is automatically generated when the mouse enters. This allow me to insert/update tables correctly. However I need the Details View for my orderDetail form too. How do I get a orderDetailID automatically generated when user insert a new order and have the mouse click on OrderDtail tab?

I am a bit of a newbie when it comes to vb.net and databases and I have a small favor to ask anyone I am looking for a very basic example on how to connect, read, update and insert data into remote mysql database. I have successfully connected to my database with the code below,, and for the moment I am just trying to LIST data from it in a listview control,, and then would like to find a way to insert data into it and update data.
Al examples I find on the net are too long and usually have too many unnecessary data around the code I need so I get a bit lost in it.Can anyone point me in the direction of SIMPLE examples that are easy to follow or provide a bit of useful code I could learn form.
