3.6.1.2 ocx (ActiveX Control Data)

This element specifies various information of an ActiveX control embedded in a document.

[Note: This element does not contain placement or application extended properties. The properties stored in this element are those that the ActiveX control can use regardless of container. end note]

[Example: Consider an ActiveX control embedded in a WordprocessingML. Various pieces of information about that control will be specified using the following WordprocessingML:

<ax:ocx ax:classid="{FDD0D569-5B7A-4E3D-820C-5C487DB7796C}" ax:persistence="persistPropertyBag" …>

<ax:ocxPr ax:name="_Version" ax:value="65536"/>

<ax:ocxPr ax:name="_ExtentX" ax:value="2646"/>

<ax:ocxPr ax:name="_ExtentY" ax:value="1323"/>

<ax:ocxPr ax:name="_StockProps" ax:value="0"/>

</ax:ocx>

Here, the classid attribute holds the class ID of the ActiveX control, {FDD0D569-5B7A-4E3D-820C-5C487DB7796C}. In this example, the persistence attribute indicates the persistPropertyBag method for persisting various properties of the control. The property bag is stored as a collection of child ocxPr elements. Each ocxPr element contains a single property. end example]
