Using system icons

I was thinking of using standard system icons via the SHGetFileInfo function specified by index; however I am concerned about the consistency of this list, will it/does it change from each version of windows, from system to system?
I.E. if index #25 was the folder icon in win98, will it also be the same index in winXP, Vista etc? If not, is there any way I can find the index of a desired icon in the standard system image list? (i.e. is there a set of constants that I could use in place of indexes to garauntee finding a certain icon?)
Thanks.

There is a function, "SHGetStockIconInfo()", however its only implemented under windows vista.. I need to find a function/method/solution of extracting an icon from the set of system icons,
thanks (bump!)
