Control is a language independent software component. Consequently ActiveX
Controls can be incorporated into a wide range of software development
environments for use by client application developers. Development environments
supported include Visual Basic, Labview, Visual C++, C++ Builder, HPVEE, Matlab,
VB.NET, C#.NET and, via VBA, Microsoft Office applications such as Excel and Word.
Consider the ActiveX Control supplied for the KBD101 APT Brushless DC Servo
driver unit.
This Control provides a complete user graphical instrument panel to allow the motor
unit to be manually operated, as well as a complete set of software functions (often
called methods) to allow all parameters to be set and motor operations to be
automated by a client application. The instrument panel reflects the current operating
state of the driver unit to which it is associated (e.g. such as motor position). Updates
to the panel take place automatically when a user (client) application is making
software calls into the same Control. For example, if a client application instructs the
associated DC motor Control to move a motor, the progress of that move is reflected
automatically by changing position readouts on the graphical interface, without the
need for further programming intervention.
