As updating an ms access db Sexwemn
We will work on reading a simple column (name) from an Access Database table (Employees) and stick those names into a listbox for selection.While there are many ways to do these things, I simply create 3 different ways that you can play with below.The code, minus exception-handling bits, looks like: Ole Db Data Adapter data Adapter = new Ole Db Data Adapter(); Data Set user Data = new Data Set(string. Remove(param User ID); // modify Data Table data user Data. 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.
We could have given it a different value than what it shows.
Just like you can give each option item in HTML select boxes a different value than its actual list item name.
The SELECT query always returns data when called on a command object using Execute Reader().
(Note that I've used this query both with and without the enclosing brackets around the field names.) Because of this failure, I attempted to use a Data Adapter instead. Update Command = update Command; Data Table dat Users = new Data Table(); retrieve Command.
