but the document not reference this variable,what is it? how i can use. thank you .Stoyan

i'm very sorry , when i use this function ,ClientToDocX function,this function have two parameters ,
long x.
long y.
this is device coordinate,but how i get it;
my screen is 1024*768,or positon of box?
this is my sample code:

    root = m_FlowChart.CreateBox(100, 30, 75, 40);
   ScriptHelper sc ;
   long *i =NULL ;
   sc.ClientToDocX(1024,768,i) ;
   long x = (long)&i ;
   x = x/2;

  ScriptHelper sc1;
  long *j = NULL ;
  sc1.ClientToDocY(1024,768,j);
  long y = (long)&j ;

  root.MoveTo(x, y) ;
  //TreeLayout tl;
     //tl.CreateDispatch(_T("FlowChartPro.TreeLayout"))
   //tl.SetRoot(root);
   //tl.SetType(tltCentralized);
   //tl.SetDirection(dir);
   //tl.SetArrowStyle(tlaStraight);
   //tl.SetNodeSpacing(15);
   //tl.SetLevelSpacing(30);
  //tl.SetKeepRootPos(TRUE);
  //tl.SetReversedArrows(FALSE);
  //tl.SetKeepGroupLayout(FALSE);
  ////m_FlowChart.ArrangeDiagram(tl);

thank you, i have not use that function ,but i do it , thank you very much.
