If PageBack() is called, PageForward() will restore the previously displayed page in the window. PageForward requires PageBack to have been called and no other page display functions to have been called in between. Calling the display functions PageDisplay or PageGoto will remove the forward pages from the display stack.
Optional parameter to specify the number of pages to move forward. Default value is 1.
CT_ERROR_NO_ERROR (0) on success. CT_ERROR_BAD_HANDLE (269) if current window handle does not correspond to a valid window. CT_ERROR_INVALID_ARG (274) if count is outside of allowable bounds.
