Method AutomationObject():setProperty() Foundation
Sets the value of a property
:setProperty( <cName> | <nID>, [<xParam, ...>] <xValue> ) --> xValue
:setProperty() returns the property value passed.
:setProperty() is used to set a value of a property exposed by a COM/ActiveX component. In case a property is accessed that is not member of the connected COM/ActiveX component, a runtime error is generated.
Normally, :setProperty() need not be called directly by applications. Instead, property values can be assigned via the assignment operator (:=).
// Property assignment via method :setProperty()
oAuto:setProperty( "Prop", oProp )
is equivalent to
// Property assignment via assignment operator
oAuto:prop := oProp
Calling :setProperty() is required when accessing a property of a COM/ActiveX component that has the same name as an instance variable of the AutomationObject. Using :setProperty() is also required to when more than one value must be passed for qualifying the property of the connected COM/ActiveX component.
The first parameter profile
:setProperty( <cName> | <nID>, <xValue> ) --> xValue
directly corresponds to normal property access via the assignment operator, eg.:
oCOM:Test := 1
The second parameter profile is used for accessing properties that require parameters for qualification. To access a cell in a grid, for instance, the corresponding call to :setProperty() might look as follows:
oGrid:setProperty( "Cells", nRow, nCol, "Cell Value" )
When values are assigned to a property, then Xbase++ data types are automatically converted to COM/ActiveX data types. See the method :callMethod() for further reference.
