The recordset object also has a Delete method, which can only be invoked through code â€“ it cannot be accessed automatically through the data control.5.
When the user clicks on the Save button to save the data that was entered, the Update method should be called and the buttons should be redisplayed.
For example, if somewhere in your program you code the statement dat Authors. Update, when VB encounters this statement, any code in the Validate event will be executed first.
The Action argument tells you which particular action (Move First, Update, etc.) caused the Validate event to fire.
The Data Source is the name of the data control on the form (it should already be configured), and the Data Field is the name of the particular field in the database that should be displayed in the control (this field will be in the table that was chosen for the Record Source of the data control).5.
On any record, change the data in the author name or year born field.
Move ahead, then move back to the record you changed. The data control automatically updates a record when you move off of the record.
Note that this exercise demonstrated that you can create a simple but functional application that allows the user to browse through the rows of a database table (or result set) and to update rows in that table without writing any code.These articles use the two sample Access databases provided with Visual Basic (BIBLIO. Then, within the folder you have created, make separate subfolder for each exercise, one level below the root of your folder.The Database Name property for the Data control in these exercises assumes that the database file resides one directory level above the folder in which the exercise project files reside.You can also invoke these methods through code, which is what this exercise demonstrates.6. Type some data in all the fields (the author ID will be entered automatically), then move to a previous record.Move back to the last record to verify that your data is still there.In the previous exercise, you saw that by clicking specific buttons of the data control, you could move to the first, previous, next, or last record.
