how to undo changes made by micro
 

Hello!

After we change cell values with our micro procedures, we can not use the
undo button to resume previous values.
How can we undo changes made by our micro procedures, as if the changes are
made in excel spread sheet by hand?

Thanks!

No built in support for it - you have to do the work. Here is one approach:

Thank you, Tom.

In the link you provided, the approach actually undo one backward step
only. After one undo, the undo button becomes disable, and there is no way to
undo backward further with the undo button.

On the other post, the procedure sounds also can only undo one step back:

Dear Zhu,

i´m sorry: after the VBA-Program has run, it is game over. Further all
previous actions in the "Undo"-list are extinguished.

It is possible to define other macros within your program to be listed as
"Undo"-Actions. (Therefor they have to be defined at the very end of the
program by Application.OnUndo "Undo : change all values" ,"MacroXX").

Best regards, Kai

I don't have a canned solution for you. You get the point, however, that
you have to store the changes and write code to undo them. If you only set
up your code to do one level of undo, then you are restricted to one level.
If you write your code to handle more than one level, then you have more
than one level. The link shows you the basics. The link you posted shows
another implementation, but it is also storing the situation before the
change.

If you want to integrate the undo with the built in undo, so you can run a
macro, make manual changes, run a macro, make manual changes, then unless
you implement that all in your own code, you are correct that it won't work.
