TextBox Control Changes in Visual Basic .NET

Visual Basic Concepts

The TextBox control in Visual Basic 6.0 is replaced by the Windows Forms TextBox control in Visual Basic .NET. The names of some properties, methods, events, and constants are different, and in some cases there are differences in behavior.

The following tables list Visual Basic 6.0 properties, methods, and events and their Visual Basic .NET equivalents. Where applicable, constants are indented beneath the property or method. All Visual Basic .NET constants map to the System.Windows.Forms namespace unless otherwise noted.

Links are provided as necessary to topics explaining differences in behavior. Where there is no direct equivalent in Visual Basic .NET, links are provided to topics that present alternatives.
