A view that displays database records in controls.
The view is a form view directly connected to a CRecordset object. The view is created from a dialog template resource and displays the fields of the CRecordset object in the dialog template's controls. The CRecordView object uses dialog data exchange (DDX) and record field exchange (RFX) to automate the movement of data between the controls on the form and the fields of the recordset. CRecordView also supplies a default implementation for moving to the first, next, previous, or last record and an interface for updating the record currently on view.
If you are working with the Data Access Objects (DAO) classes rather than the Open Database Connectivity (ODBC) classes, use class CDaoRecordView instead. For more information, see the article Overview: Database Programming.
The most common way to create your record view is with the Application Wizard. Tge Application Wizard creates both the record view class and its associated recordset class as part of your skeleton starter application. If you don't create the record view class with the Application Wizard, you can create it later with ClassWizard. If you simply need a single form, the Application Wizard approach is easier. ClassWizard lets you decide to use a record view later in the development process. Using ClassWizard to create a record view and a recordset separately and then connect them is the most flexible approach because it gives you more control in naming the recordset class and its .H/.CPP files. This approach also lets you have multiple record views on the same recordset class.
To make it easy for end-users to move from record to record in the record view, the Application Wizard creates menu (and optionally toolbar) resources for moving to the first, next, previous, or last record. If you create a record view class with ClassWizard, you need to create these resources yourself with the menu and bitmap editors.
For information about the default implementation for moving from record to record, see IsOnFirstRecord and IsOnLastRecord and the article Using a Record View.
CRecordView keeps track of the user's position in the recordset so that the record view can update the user interface. When the user moves to either end of the recordset, the record view disables user interface objects — such as menu items or toolbar buttons — for moving further in the same direction.
