How to include a function call as a parameter in another function?

[C_Huegel]

For example:

Public Function RefreshPages(ctl1 as control, ctl2 as control, ctl3 as control, sub_name as ??????)
 
     ctl1.do something
     ctl2.do something
     ctl3.do something
 
     'now call the sub or function that was passed as a paramater
 
     sub_name()
 
End Function

So whenever i finish doing whatever with the controls that the function was passed, i can then call the sub or function that was also passed.
