Tor Lillqvist 2b6a84c8f6 We might need to handle form controls as properties for OLE clients after all 
Start a bit of work on that.

// "convertDispparamsArgs" converts VARIANTS to their respecting Any counterparts
// The parameters "id", "wFlags" and "pdispparams" equal those as used in
// IDispatch::Invoke. The function handles special JavaScript
// cases where a VARIANT of type VT_DISPATCH is ambiguous and could represent
// an object, array ( JavaScript Array object), out parameter and in/out ( JavaScript Array object)
// parameter (JavaScript Array object)
// Because all those VT_DISPATCH objects need a different conversion
// we have to find out what the object is supposed to be. The function does this
// by either using type information or by help of a specialized ValueObject object.
// A. Type Information
// With the help of type information the kind of parameter can be exactly determined
// and an appropriate conversion can be chosen. A problem arises if a method expects
// an Any. Then the type info does not tell what the type of the value, that is kept
// by the any, should be. In this situation the decision whether the param is a
// sequence or an object is made upon the fact if the object has a property "0"
// ( see function "isJScriptArray"). Since this is unsafe it is recommended to use
// the JScript value objects within a JScript script on such an occasion.
// B. JavaScript Value Object ( class JScriptValue )
// A JScriptValue (ValueObject) object is a COM object in that it implements IDispatch and the
// IJScriptValue object interface. Such objects are provided by all UNO wrapper
// objects used within a JScript script. To obtain an instance one has to call
// "_GetValueObject() or Bridge_GetValueObject()" on an UNO wrapper object (class InterfaceOleWrapper).
// A value object is appropriately initialized within the script and passed as
// parameter to an UNO object method or property. The convertDispparamsArgs function
// can easily find out that a param is such an object by querying for the
// IJScriptValue interface. By this interface one the type and kind ( out, in/out)
// can be determined and the right conversion can be applied.
// Using ValueObjects we spare us the effort of acquiring and examining type information
// in order to figure out what the an IDispatch parameter is meant for.
// Normal JScript object parameter can be mixed with JScriptValue object. If an
// VARIANT contains an VT_DISPATCH that is no JScriptValue than the type information
// is used to find out about the required type.
