Add/delete Data From A Specific Table In The Database?
Apr 8, 2011
I have a Form1 that is the main application form, that display certain data from a database. Then I have Form2 that add/delete data from a specific table in the database.My problem is, When I add data to the database, and save it, it work fine, But, it does not reflect on the main form, after I close Form2. Only when I exit the application, and open it again, it shows. Is there a setting or something I need to do to update/refresh the info added so I do not need to restart the application?

you would think that this would be simple, but with some sample code i found i could only get it to load and not save, or it would be written for a datagrid and not a datagridview.

I have a datasource linked to a table in a database.When I wnated to display this data on a form, I just dragged the datasource onto the form and it did everything for me, including the code to fill it;
Me.ProjectFileTableAdapter.Fill(Me.ProjectFileDataSet.ProjectFile)
My problem, is that this program will have multiple users, and I don't other users to be able to see each others data. So the problem with the above statement is that it fills the table with ALL the data in the datasource. How can I make it only display data that is for a specific user?Here's the code that is used to fill the tableadapter:
