move layer up and down doesn't work

yosiwidiyanto — Sat, 16 Oct 2010 09:46:34 GMT

I???m writing code with vba to build tool layer order (move layer up and down), switch from data view to layout view conversely, and turn on and off layer. I have 2 layers named river and lake. What I want is in data view: the position of layer (0) is river and lake is invisible. And in layout view: the position of layer (0) is lake and river is invisible. The result is layer only move one time every after opening file mxd, whatever the selected layer is, the 2nd run and so on only switching and turning on or off layer. And surprisingly, although the layer lake is invisible but I can see in layout view.
Below are my code and no error. Could anyone please tell me where the mistake is?
Thanks
