Thanks for your help.
I'm still trying to solve the loss of the cut/copy/paste when using code like .calculate or .calculation
There are already some options, but they all have there restrictions. Most only keep the values to copy. Others use pasting the copied range to extract the address from the formula, but that doesn't work with "cut"!
Using the previous selection as the cut/copy range together with GetClipboardSequenceNumber to know there is an new cut/copy is the best way, but that doesn't work when using undo/redo. Because last selection isn't the cut/copy range!

So I was thinking on checking and counting undo.redo and hold the according cut/copy range in memory. I could just count the differences with the previous amount of unod/redo's but this doesn't work when redo the last one. Because the undo/redo amount is the same as typing in something new and thereby adding an undo and deleting the last redo.

Now I'm trying to read the office-clipboard ("bosa_sdm_XL9", "Collect and Paste 2.0") it's there but I can't seen to get the data from the screen in the code. So where can I find out how to read these "windowless label controls" ?

thanks
