C updating database

Almost on a daily basis we run across posts that ask about using a . Oh it might have a slight variation like “How do I load a value from a database into a textbox?” or “How do I read a database into _______ control and then update the database?The second method I will show you is again using a dataset but this time we will loop through it to load the listbox.This method is good for times where you want to modify each value before adding it to the listbox.

We will work on reading a simple column (name) from an Access Database table (Employees) and stick those names into a listbox for selection.The first example will be to use a Data Adapter class and its fill method to load it into a Data Set.Think of this method like using a hose to fill up a bucket.Once we have it in the bucket, we can use the data independent of the connection or adapter.This example will use the Data Set to “bind” to the listbox and empty its contents into the listbox control. The only trick here is that we bind the database to the listbox and tell the listbox to use the name column as both the names we display to the user as well as the value each item has.It is also good in that it is directly tied to the dataset itself.So if we modify the dataset, the listbox automatically changes as well.Nothing much to see here other than how to create the class and use a connection string to tell the connection where to find the database.Since we now have a database connection made, we have a few choices on how to query and load our data. Some have their advantages and disadvantages, so be sure to research which one might fit your needs the most.These are my codes: public partial class Edit Permit : Form { Ole Db Command command; Ole Db Data Adapter da; private Binding Source binding Source = null; private Ole Db Command Builder ole Command Builder = null; Data Table data Table = new Data Table(); public Edit Permit() private void Edit Permit Permit_Load(object sender, Event Args e) private void btn Sv_Click(object sender, Event Args e) private void Data Bind() I have the same kind of project at home, I do not have the source code with me but if needed I can check somewhere this weekend to see what exactly I have done, but I believe it's some of the following: Since you are using a I have implemented a solution that inserts/updates/deletes data in MS SQL database directly from Data Grid View.To accomplish this I have used the following events: Row Validating and User Deleting Row.
