Element.License Property (ExSurface)

The control supports ActiveX hosting, or in other words, any element can host another inside controls. The License property indicates a string expression that indicates the runtime license key for the component being inserted, if required. Only, the vendor of the component you are going to use is able to give you such of runtime license, so please contact the control's vendor for such of key. Your development license key is not compatible with the runtime license key, so it can't be used here. The Control property has effect only if the element's Type property is set on exElementHostControl. If you insert a runtime-licensed control you must specify the License property before calling the Control property. Use the ElementFormat property to specify the area where the inner control is displayed. The Object property returns a reference to newly created control. The ExSurface control fires the OLEEvent event if an inside ActiveX control fires an event.

The Control property must be formatted in one of the following ways:

A ProgID such as "Exontrol.Grid"
A CLSID such as "{8E27C92B-1264-101C-8A2F-040224009C02}"
A URL such as "https://www.exontrol.com"
A reference to an Active document such as "c:\temp\myfile.doc", or "c:\temp\picture.gif"
A fragment of HTML such as "MSHTML:<HTML><BODY>This is a line of text</BODY></HTML>"
A fragment of XML

The look and feel of the inner ActiveX control depends on the identifier you are using, and the version of the library that implements the ActiveX control, so you need to consult the documentation of the inner ActiveX control you are inserting inside the exSurface control.
