Recalculates all dynamic properties in the current document.
HRESULT retVal = object.recalc(fForce);
- fForce [in, optional]
A VARIANT_BOOL that specifies one of the following values.
If this method succeeds, it returns S_OK. Otherwise, it returns an HRESULT error code.
There are no standards that apply here.
Implicit dependencies, internal property changes, and related properties can cause some expressions not to recalculate, even though the referenced properties might have changed. For example, resizing the main window changes the IHTMLElement2::clientWidth property. Expressions that reference IHTMLElement2::clientWidth might not be recalculated, because the change might not be recognized.
Implicit dependencies refer to properties that can be modified by changes in other properties. For example, the IHTMLScreen::height property of a div object implicitly depends on the IHTMLElement::innerHTML property of the div object. However, if an expression references the IHTMLScreen::height property, a change in the IHTMLElement::innerHTML property, which might modify the IHTMLScreen::height, does not cause a recalculation of the expression on a subsequent call to IHTMLDocument3::recalc.
Related properties can access or manipulate data or behaviors through one or more other properties. For example, IHTMLStyle::pixelLeft and IHTMLStyle::posLeft can set or get the left position of the element. However, if an expression that references IHTMLStyle::pixelLeft and IHTMLStyle::posLeft is modified, the expression might not be recalculated on subsequent calls to IHTMLDocument3::recalc.
Related properties that can cause this behavior include the following: IHTMLElement2::clientHeight, IHTMLElement2::clientLeft, IHTMLElement2::clientTop, IHTMLElement2::clientWidth, IHTMLScreen::height, IHTMLRuleStyle::left, IHTMLElement::offsetHeight, IHTMLElement::offsetLeft, IHTMLElement::offsetTop, IHTMLElement::offsetWidth, IHTMLStyle::pixelHeight, IHTMLStyle::pixelLeft, IHTMLStyle::pixelTop, IHTMLStyle::pixelWidth, IHTMLStyle::posHeight, IHTMLStyle::posLeft, IHTMLStyle::posTop, IHTMLStyle::posWidth, and IHTMLRuleStyle::top.
To force the recalculation of all expressions, refer to the same property name or manually call IHTMLDocument3::recalc(true).
