I'll try to explain in more detail what I plan to do.
I have got a table like the following containing the composition of
several streams in a chemical process:

component stream 1 stream 2 stream 3 ...
COMP1 1 t/h 0.2 t/h ....
COMP2 0.5 t/h ....
COMP3 2 t/h ....
....

Further I have a flowsheet of the process as for example shown he
http://de.wikipedia.org/wiki/RI-Flie%C3%9Fbild.

What I want to do is to draw textboxes for each stream into this
flowsheet and copy the content from the table into the respective
textbox.

Since I will run several simulations I would like to update the data
in the textboxes without having to redraw and replace them.
A sub or function of this type would be nice:

update_textbox(textbox_ID As WhatEver, cells_to_copy_into_textbox As
Range)

Thanks for suggestions
