Method AutomationObject():invoke() Foundation
Invokes a method or property.
:invoke( <cName> | <nID>, <nNamedArgs>, <nFlags> [, <xParam, ...>] ) --> xValue
Constant | Usage |
---|---|
DISPATCH_METHOD | Call a method or set a property with more then one parameter |
DISPATCH_PROPERTYGET | Get a property value |
DISPATCH_PROPERTYPUT | Set a property value |
DISPATCH_PROPERTYPUTREF | Set a property value by reference |
|
The result depends on the return value of the method or property that is invoked. In case a method or property is invoked which is not known to the ActiveX component, a runtime error occurs.
:invoke() can be used to accessing elements of a COM/ActiveX object. This element can be either a method or a property. A property can be invoked for read or write access.
Normally, :invoke() does not need to be called directly. The methods :callMethod(), :setProperty() or :getProperty() should be used instead.
When methods are called or properties are accessed, then Xbase++ data types are automatically converted to/from COM/ActiveX data types. See the method :callMethod() for further reference.
