Load Sheet to Memory in TTY Mode

The PmLoadSheet object can be used to load the graphical representation of a SHEE element to the memory. This is necessary before certain other objects can be used in TTY mode, for example, the PmlRevisionControlobject. Refer to PML Customisation Support for Revision Control Snapshot Capability for further information. Loading a sheet in graphical mode using PmlLoadSheet is also possible, this does not cause the sheet to be displayed on the canvas. Refer to Accessing DRAW 2D View for further information.

Only one sheet can be loaded at any time, irrespective of how many PmlLoadSheet objects are created. Loading a second sheet causes the first sheet to close. It is important to call the Close() method when finished to free resources associated with the sheet. PmlLoadSheet can also be used in graphical mode, although other pml objects will always use the current canvas sheet (if any) in preference over a sheet loaded via the pml object.
