我试过用getscrollrange得到滚动条的范围,然后用setscrollpos,滚动条是拉下来了,但是文本却还是第一行,怎么解决呢?

  cedit   overview   |   class   members   |   hierarchy   chart   |   cedit::lineindex  
  call   this   function   to   scroll   the   text   of   a   multiple-line   edit   control.  
   
  void   linescroll(  
        int   nlines,  
        int   nchars   =   0    
  );  
  parameters  
  nlines    
  specifies   the   number   of   lines   to   scroll   vertically.    
  nchars    
  specifies   the   number   of   character   positions   to   scroll   horizontally.   this   value   is   ignored   if   the   edit   control   has   either   the   es_right   or   es_center   style.    
  remarks  
  this   member   function   is   processed   only   by   multiple-line   edit   controls.    
   
  the   edit   control   does   not   scroll   vertically   past   the   last   line   of   text   in   the   edit   control.   if   the   current   line   plus   the   number   of   lines   specified   by   nlines   exceeds   the   total   number   of   lines   in   the   edit   control,   the   value   is   adjusted   so   that   the   last   line   of   the   edit   control   is   scrolled   to   the   top   of   the   edit-control   window.    
   
  linescroll   can   be   used   to   scroll   horizontally   past   the   last   character   of   any   line.  
   
  for   more   information,   see   em_linescroll   in   the   platform   sdk.  
   
  example  
  see   the   example   for   cedit::getfirstvisibleline.
