Hello all,
I want to open a text file after pressing the OK button in a message box, but I do not know how to do that.
I tried with a switch code, but it did not work.
If you know how to do that, please tell me.
Thank you !

Where is the file coming from? Why is it any different opening it after clicking an OK button to doing it anywhere else? If it is a message box I assume you don't mean uigetfile that returns a filename?

The file is a .txt that states the date and time of any block change in a Simulink model. If there is a change, a dialog box appears and after the user clicks the OK button I would like to open instantly the log file.
