Sorry guys, but I deduct from your replies that I definitely did not express myself clearly enough. Sorry. Here I try again
For a given (or known) cell, I can find the x and y coordinates by invoking the .left and .top properties of the range. Typically this is
x=thisworkbook.worksheets(1).cells(10,10).lef
y=thisworkbook.worksheets(1).cells(10,10).to
What I need is the opposite i.e. find the range object, given 2 integers that represent the x and y in the same units as are expressed .left and .top above. Do you know how to find that 1-cell range object given those x and y?
