Because a few features in our C and Delphi versions are not implemented in our VB RT Tools. For example, VB has its own controls and event handling structure built-in, so we don’t supply our controls in the VB version of the RT Tools.

Therefore, the related callback functions for alarm events, DDE, and Quinn-Curtis child controls are not supported. – Control Objects – Visual Basic controls, such as various button types and scroll bars, can be used to provide essential input capabilities for instrument interfaces. These VB Controls are used in place of the Quinn-Curtis controls found in the C and Delphi versions of the tools. – DDE – display data provided by a server application.
