I have a macro which is normally invoked by a button on a worksheet. Before
the macro is run, there is a MsgBox prompt asking for confirmation.

Now I want to call this macro from another macro. In this case, I want to
skip the MsgBox prompt part and go ahead with the macro right away.

How can I check whether the macro has been called by a button or another
macro? Or is there a better way handling this problem?

TIA
