KTP stands for potassium titanyl-phosphate; the KTP laser is used to treat blood vessels on the face and redness from rosacea. The KTP laser treatment can give a dramatic improvement in the appearance of redness and vessels on the face in only one to two treatments.
ActiveX control. An ActiveX control is a component program object that can be re-used by many application programs within a computer or among computers in a network. The technology for creating ActiveX controls is part of Microsoft's overall ActiveX set of technologies, chief of which is the Component Object Model (COM).
Summary. By combining multiple controls into one custom control, you can create a complex mix of code and layout that can be easily packaged and distributed. This style of control is useful for something simple, such as combining a Label and a TextBox, or for something complex, such as a complete address entry control. Regardless of how you use this style of control, it is the closest in form to the ActiveX control development model of Visual Basic 5.0 and 6.0.
