[求助]：如何向setWindowPos传递点坐标

zhoufs_1205

请问高手：
    我想实现在CAD中当鼠标放开时，对话框弹出，且左上角为鼠标处。鼠标放开返回AcGePoint3d，如何向setWindowPos传递点坐标。

AcGePoint3d p1,p2;
        acedGetPoint(NULL,"\n Select pOINT:",asDblArray(p1));
        ZhouAcEdJig *pJig=new ZhouAcEdJig(p1);
        p2=pJig->doIt();//由鼠标拖动返回点
        delete pJig;
        pDialog=new ZhouDialog(acedGetAcadFrame());
        pDialog->Create(IDD_DIALOG1);
        pDialog->ShowWindow(SW_SHOW);
        pDialog->SetWindowPos(acedGetAcadDockCmdLine(),p2[X],p2[Y] ,0,0,SWP_NOSIZE);

该成以下后还不行
        AcGePoint3d p1,p2;
        CPoint p3;
        CString str;
        acedDwgPoint cpt;
        acedGetPoint(NULL,"\n Select pOINT:",asDblArray(p1));
        ZhouAcEdJig *pJig=new ZhouAcEdJig(p1);
        p2=pJig->doIt();//由鼠标拖动返回点
        delete pJig;
        pDialog=new ZhouDialog(acedGetAcadFrame());
        pDialog->Create(IDD_DIALOG1);
        pDialog->ShowWindow(SW_SHOW);
        //
        cpt[0]=p2[X],cpt[1]=p2[Y];
        acedCoordFromWorldToPixel(0,cpt,p3);
        //
        str.Format("%g",p2[X]);
        pDialog->m_edit1.SetWindowText(str);
        pDialog->m_edit1.UpdateData();
    str.Format("%g",p3.x);
        pDialog->m_edit2.SetWindowText(str);
        pDialog->m_edit2.UpdateData();

        pDialog->SetWindowPos(acedGetAcadDockCmdLine(),p3.x ,p3.y ,0,0,SWP_NOSIZE);


请帮我想想办法

你要把那个函数定义成HOOK，就能动态监视鼠标的动作了。

我的意思是说：
  p2返回的是wcs坐标，而pDialog->SetWindowPos(acedGetAcadDockCmdLine(),p2[X],p2[Y] ,0,0,SWP_NOSIZE); 显然这样是错误的，需要将p2转换为窗体的坐标，怎么办？
