How to check if OK is pressed or not in a msgbox

Hi,

I would like to know how I can check if OK is pressed or not in a msgbox

I tried using strcmp but there seems to be a problem.

       Button = msgbox(sprintf('The TryNumber is %d.\nClick OK to Stop',TryNumber));
       if strcmp(Button , 'OK')
          #do_something
       else
          #do_something
       end

Can somebody help me resolve this issue. Thank you.

The msgbox help shows that the output is a figure object. Why are you using strcmp on a graphics object?

Note that a msgbox only has one button "OK": what do you want the user to do that would run your alternative code?

Thank you very much for your response. Yes, I figured it out. I managed to do it using isgraphics command.

Try using questdlg() instead:

promptMessage = sprintf('Do you want to Continue processing,\nor Quit processing?');
titleBarCaption = 'Continue?';
buttonText = questdlg(promptMessage, titleBarCaption, 'Continue', 'Quit', 'Continue');
if contains(buttonText, 'Quit')
  return;
end

Thank you very much for your response. This message appears in each iteration in a loop. So while using questdlg I need to press 'continue' or 'quit' or something during each iteration. So it was not ideal for my project. But other than that it works fine. Thank you for your time.

You could add a third option for "non-stop" where if they click that, you set a flag where you basically don't ask them anymore.
