The IT GmbH offers also a collection of controls. The Professional ActiveX library from iocomp iocomp includes 56 both graphicaly and technicaly high quality controls, you can use in Elvis since version 2.2.

You can buy the iocomp controls directly here. The IT GmbH has purchased OEM-licenses of the iocomp Professional controls (= Instrumation Pack Pro) for developers and offers them on very good terms: the regular price of an iocomp Professional License is US$ 895.-, we offer this license to our Elvis developers for 350,- Euro.
You get a good overview over the 56 controls of the professional package at Instrumation Pack Pro and Demoversion.
The Developer License is not limited to a number of projects. On the computer, where you develop the Elvis visualisation, you have to install the licenced iocomp controls (there is a separate setup).
On the computer, where the visualisation is running (terminal), you are only allowed to install the Runtime setup of the controls. In Elvis version 2.5 and higher, the Runtime setup of the iocomp controls is integrated.
You can also use ActiveX controls in Elvis, which are not from IT GmbH. But often it is difficult to find out the function of an unknown control because of a faulty documentation.
