ACTIVEX (ocx) COMPONENTS FOR VISUAL BASIC

Download these free versions of our "ec" components and try them out.  They are fully functional, but will display a small demo message.  To convert them to registered versions without the message,  purchase a license and registration key from us.  There are no royalty or runtime fees for distributing the registered components with your compiled applications.

Powerful 2D graph plotting ActiveX control for Visual Basic applications.  Add it to your programs to create graphs in a huge range of styles.  Get a graph up and running with just a few lines of code, and manipulate the graph layout from your own programs.  Zoom and scroll;  multiple x- and y-axes per graph;  plot data points, bars, math functions, text;  log or linear scales;  multiple graphs per page;  click and drag to move or resize graphs on the page;  demo projects   supplied to show how all the features work;  hundreds of other features.

ecMathExpr

Compile and evaluate math functions & expressions in Visual Basic applications.  Much faster than simple math parser routines. Define any number of variables and assign values to them.  Define up to 20 'user-defined' functions to use in other math expressions.  Compile any number of math expressions that can use the pre-defined variables and user functions. Evaluate (fast and repeatedly) any of the compiled expressions.  Includes trigonometric and hyperbolic trig functions, logarithmic and exponential, logical function such as IIf(condition, truepart, falsepart), max and min, random, arithmetic and boolean operators, logical and conditional operators.
