Extended data with ODA library

Hi!

I have read about extended data for some time and I am currently trying to store the value of the attributes of a block (the block used is the standard that opens with the CAD, a block to make the electrical design) in the extended data, but I am encountering difficulties. The program is not doing anything the way I did and it's been a while since I'm trying to modify this code, but I do not know what I could do differently. This is trying to put in the extended data the value of the insertion point of the block and then the part of all the attributes of the block (but this still barely started because I am well lost).
If anyone can help me I really appreciate it and I notice that I am very lay person myself, I learned c ++ a short time ago and now I am venturing into this library to program to CAD.


I'm programming in C ++ in Visual Studio using the ODA library to make applications for CAD.

Code:

        const CString string = "Select a block: ";
        CString code = "POINTS_APP";

        fdt_point objPoint;
        fdt_name ename;
        fdt_name nextName;
        fdt_point point;

        OdDbObjectId objID;

        ACTIVE_DOCUMENT()->GetFxAPI()->fdt_entselW(string, ename, point);
        ACTIVE_DOCUMENT()->GetFxAPI()->GetObjectId(ename, objID);
        ACTIVE_DOCUMENT()->GetFxAPI()->fdt_entnext(ename, nextName);
       
        fdt_resbufW * objList = new fdt_resbufW();
        objList->restype = RTSTR;
        objList->resval.rstring = _T("*");

        fdt_resbufW * objEnt = ACTIVE_DOCUMENT()->GetFxAPI()->fdt_entgetxW(ename, objList); //entget
        fdt_resbufW * aux = objEnt;
        fdt_resbufW * aux2 = ACTIVE_DOCUMENT()->GetFxAPI()->fdt_entgetxW(nextName, objList);

        while(aux2 != NULL)

                if(aux2->restype == 10)
                {

                        objPoint[1] = aux2->resval.rpoint[1];
                        objPoint[2] = aux2->resval.rpoint[2];
                }
                aux2 = aux2->rbnext;
        }
        while(aux->rbnext!=NULL)
        {
                aux = aux->rbnext;
        }
       
        fdt_resbufW * objListApp = new fdt_resbufW();
        objListApp->restype = RTSHORT;
        objListApp->resval.rint = -3;
       
        objListApp->rbnext = new fdt_resbufW();
        objListApp->rbnext->restype = 1001; //appname

        objListApp->rbnext->resval.rstring = _T("POINTS_APP");
       
        objListApp->rbnext->rbnext = new fdt_resbufW();
        objListApp->rbnext->rbnext->restype = 1010; //3D point
        objListApp->rbnext->rbnext->resval.rpoint[0] = objPoint[0];
        objListApp->rbnext->rbnext->resval.rpoint[1] = objPoint[1];
        objListApp->rbnext->rbnext->resval.rpoint[2] = objPoint[2];
        aux->rbnext = objListApp;
        ACTIVE_DOCUMENT()->GetFxAPI()->fdt_entmodW(objEnt);

        return 0;
