ARCgis engine开发，添加指北针的时候出错了！

[worldofwest]

pPoint = formTemp.returnPageLayoutControl().ActiveView.ScreenDisplay.DisplayTransformation.ToMapPoint(X, Y);
xMap = pPoint.X;
yMap = pPoint.Y;
formTemp.returnTextbox1().Location = new System.Drawing.Point(X,Y);
formTemp.returnTextbox1().Visible = true;
formTemp.returnTextbox1().Focus();
formTemp.returnTextbox1().Text = "请在此输入图名";


returnPageLayoutControl()这个函数不存在！
