// Layout Utilities sample code [[ TestPrint ]] for VCS2008
//
// This program is the basic print sample cord which used a layout file.
// In addition, please understand that error processing is not performed.
//
// The command procedure that is necessary for print is as follows.
//
// [01] Creates the object.
// [02] Opens the layout file.                           Open
// [03] Initializes the object.                          BeginPrint
// [04] Gets an index of the frame.                      InitFrame
// [05] Gets an index of the part in the frame.          GetParts
// [06] Modifies the working area in the object.         SetPartsData
// [07] Copies the working area to the print area.       AddFrame
// [08] Starts the print.                                DoPrint
// [09] Cancels the work area.                           EndPrint
// [10] Clears all area in the object.                   Close
