I am looking for a way to run a VBA macro automatically when the text in a text box overflows. With the help from this community, I was able to develop a macro and now I am looking for a way to run or trigger it. I have read many posts regarding how to trigger an event in MS Word to run a macro. However, there seem no good solutions. The existing methods are all when the documents are opened, created or closed. They are not what I need. I need the macro to be run (and the results will be displayed) when users are using the documents. Any suggestions?
