How to get the number of page which exists the change bar ?

Question

In FDK development, I want to find the number of page which exists the change bar.

zhaopeng,
You can get the page number by querying the FP_PageNum property of the FO_Page object:
pageNum = F_ApiGetInt(docId, pageId, FP_PageNum);
...or you can use FP_PageNumString if you are using string page numbers.
If you do not have the ID of the FO_Page object, you can get it from the paragraph ID using the following function, courtesy of Rick Quatro, posted to the Yahoo Framedev list. Send the paragraph (FO_Pgf) ID as oObj and it will return the page ID:
F_ObjHandleT GetPage(F_ObjHandleT oDoc, F_ObjHandleT oObj)
F_ObjHandleT oFrame = 0;
IntT iObjType;
F_ObjHandleT oRow, oCell;
while(oObj)
oFrame = oObj;
iObjType = F_ApiGetObjectType(oDoc, oObj);
switch(iObjType){
case FO_SubCol:
oObj = F_ApiGetId(oDoc, oObj, FP_ParentTextFrame);
break;
case FO_Tbl:
oRow = F_ApiGetId(oDoc, oObj, FP_FirstRowInTbl);
oCell = F_ApiGetId(oDoc, oRow, FP_FirstCellInRow);
oObj = oCell;
break;
case FO_Row:
oCell = F_ApiGetId(oDoc, oObj, FP_FirstCellInRow);
oObj = oCell;
break;
case FO_Cell:
// handle FO_Pgf case
case FO_Pgf:
// handle FO_AFrame case
case FO_AFrame:
oObj = F_ApiGetId(oDoc, oObj, FP_InTextFrame);
break;
// handle graphic object cases
case FO_TextLine:
case FO_TextFrame:
case FO_UnanchoredFrame:
case FO_Arc:
case FO_Ellipse:
case FO_Group:
case FO_Inset:
case FO_Line:
case FO_Math:
case FO_Polygon:
case FO_Polyline:
case FO_Rectangle:
case FO_RoundRect:
oObj = F_ApiGetId(oDoc, oObj, FP_FrameParent);
break;
default:
// prevents loop if unknown object type is found.
oObj = 0;
break;
if(oFrame){
// Use FP_PageFramePage to get the page identifier of the object.
return (F_ApiGetId(oDoc, oFrame, FP_PageFramePage));
else
return(0);
