MaskEdBox Control for Visual Basic 6.0 Users
The MaskEdBox control in Visual Basic 6.0 is replaced by the Windows Forms MaskedTextBox control in Visual Basic 2008. The names of some properties, methods, events, and constants are different, and in some cases there are differences in behavior.
Conceptual Differences
In Visual Basic 6.0, the AutoTab property determines whether the next control in the TAB order receives focus as soon as the Text property of a MaskEdBox control is filled with valid data.
In Visual Basic 2008, there is no equivalent for the AutoTab property. You can achieve the same effect by monitoring and validating the input, and setting the focus to the next control yourself.
In Visual Basic 6.0, the PasswordChar property is of type String; in Visual Basic 2008 it is of type Char.
In addition, there are numerous conceptual differences that apply to all controls, including differences in data binding, font handling, drag-and-drop, Help support and more. For more information, see Windows Forms Concepts for Visual Basic 6.0 Users.
MaskedEdBox Control Property, Method, and Event Equivalencies
The following tables list Visual Basic 6.0 properties, methods, and events, along with their Visual Basic 2008 equivalents. Those properties, methods, and events that have the same name and behavior are not listed. All Visual Basic 2008 enumerations map to the System.Windows.Forms namespace unless otherwise noted.
This table provides links to topics explaining behavior differences. Where there is no direct equivalent in Visual Basic 2008, links are provided to topics that present alternatives.

Upgrade Notes
When a Visual Basic 6.0 application is upgraded to Visual Basic 2008, any MaskEdBox controls are upgraded to Windows Forms MaskedTextBox controls, and properties, methods and events are upgraded to their equivalents. Where there may be differences in behavior, upgrade comments are inserted into the code.
