> ## RGB-VALUE function

> Returns an integer that represents a combination of a red, green, and blue color value. This function allows you to define an arbitrary color, expanding beyond those colors defined in the color table.

> #### Syntax

>     RGB-VALUE ( redval , greenval , blueval )

> ``redval`, `greenval`, `blueval``

> Identifies red, green, and blue color values which can be combined to define a unique color value.

> Example

> The following code fragment shows how to set the background color of an ActiveX control:

>     DEFINE VARIABLE hdlControl AS COM-HANDLE.
>     /* Complete code to get a handle to a control in a control-frame.*/
>     .
>     .
>     .
>     hdlControl:BackColor = RGB(128, 0, 256).

> For detailed information on programming ActiveX Controls, see OpenEdge Development: Programming Interfaces manual.
