//===========================================================================
// Summary:
//     CSPPropertyGridItemNumber is a CSPPropertyGridItem derived class.
//     It is used to create an integer value item in a Property Grid control.
//===========================================================================
class  CSPPropertyGridItemNumber : public CSPPropertyGridItem
{
public:

	//-----------------------------------------------------------------------
	// Summary:
	//     Constructs a CSPPropertyGridItemNumber object
	// Parameters:
	//     strCaption  - Caption of the item.
	//     nID  	   - Identifier of the item.
	//     nValue      - Initial value of item.
	//     pBindNumber - If not NULL, then the value of this item
	//  				 is bound the value of this variable.
	// Remarks:
	//     Class CSPPropertyGridItemNumber has no default constructor.
	//
	//  		When using the second constructor, the Identifier (nID) of the
	//  		second constructor can be linked with a STRINGTABLE resource
	//  		with the same id in such form "Caption\\nDescription".
	//
	//  		BINDING:
	//  		  Variables can be bound to an item in two ways, the first is
	//  		  to pass in a variable at the time of creation, the second allows
	//  		  variables to be bound to an item after creation with the
	//  		  BindToNumber member.
	//
	//  		  Bound variables store the values of the property grid items
	//  		  and can be accessed without using the property grid methods
	//  		  and properties.  Bound variables allow the property grid to
	//  		  store data in variables.  When the value of a PropertyGridItem
	//  		  is changed, the value of the bound variable will be changed to
	//  		  the PropertyGridItem value.  The advantage of binding is that
	//  		  the variable can be used and manipulated without using
	//  		  PropertyGridItem methods and properties.
	//
	//  		  NOTE:  If the value of the variable is changed without using
	//  		  the PropertyGrid, the PropertyGridItem value will not be
	//  		  updated until you call CSPPropertyGrid::Refresh.
	// See Also: BindToNumber
