Retrieves the height of the object relative to the layout or coordinate parent, as specified by the IHTMLElement::offsetParent property.
Syntax
HRESULT IHTMLElement::get_offsetHeight(long *p);
Parameters
- p
- Pointer to a variable of type long that
receives the height, in pixels.
Return Value
Returns S_OK if successful, or an error value otherwise.
Remarks
You can determine the location, width, and height of an object by using a combination of the IHTMLElement::offsetLeft, IHTMLElement::offsetTop, IHTMLElement::offsetHeight, and IHTMLElement::offsetWidth
properties. These numeric properties specify the physical coordinates
and dimensions of the object relative to the object's offset parent.
For
more information about how to access the dimension and location of
elements on the page through the Dynamic HTML (DHTML) Document Object
Model (DOM), see Measuring Element Dimension and Location.
To comply with the Cascading Style Sheets, Level 1 (CSS1) 
box model, Microsoft Internet Explorer 6 and later calculate the height of objects differently when you use the !DOCTYPE declaration in your document to switch on standards-compliant mode. This difference may affect the value of the IHTMLElement::offsetHeight propety. When standards-compliant mode is switched on, the IHTMLStyle::height
property specifies the distance between the top and bottom edges of the
bounding box that surrounds the object's content. When
standards-compliant mode is not switched on, and with earlier versions
of Windows Internet Explorer, the IHTMLStyle::height property also includes the IHTMLStyle::border and IHTMLStyle::padding belts that surround the object's bounding box. For more information, see CSS Enhancements in Internet Explorer 6.
