System Image List

My class declaration
class CFileListCtrl : public CFileList
In an instance of my class CFileListCtrl i need
access to the system image list which I get thrue
the usual way described here on codeguru's pages.
SHGetFileINfo that is....
I got two problems,
1.
I have five instances of CFileListCTrl in my application (a MDI application). Since it seem you can only get one HANDLE to the system image list how am I suppose to give access to all my CFileListCtrl. make it global or what?
2.
Because I have a MDI application theres a problem when i open a new MDI window which also needs a system image list. Should I Detach() the system Image List every time the MDI window goes out of scope or what?

You know how to get the system image list, right? Then do something like this.

CImageList myImgList;
myImgList.Attach(hSystemImgList);
myListCtrl.SetImageList(&myImgList,LVSIL_NORMAL);
myImgList.Detach();



I've done it before, and it works.
