OK button does not work..

Hello,

I am using the below code, but when I click OK in popup window, Nothing is displayed. The code resumes when the popup window is closed.

message = sprintf("Hello World!\nClick the OK button to continue');
uiwait(msgbox(message));
disp('This will print after you click Continue');

Oshin, use

 message = sprintf('Hello World!\nClick the OK button to continue');

instead. Notice the single prime (') in front of the Hello.

The error msg you are receiving now ("Subscript indices...") indicates that the issue is located somewhere else in your code. I recommend posting a separate question for that.

Please post follow-up questions and comments as comments , not as answers.

Please help... The code is given below:

try to run the execute only the "process" tab as the error occurs in the shell1 code only.

Answer 2

[oshin]

Thank you for the help. I have already corrected that mistake. The main issue is that if I am running the code as a standalone code it is running successfully but if the gui and database are connected with the same code, then this type of error is occuring:

"Subscript indices must either be real positive integers or logicals.

Error using waitfor Error while evaluating uicontrol Callback"

 and after the error,if the same code ie without gui and database is executed,it continuously gives the same error again and again.

Please post comments to answers in the corresponding comment section and open a new thread for a new problem. Then post a complete copy of the error message and the line of code, which causes the error.

Did you redefine the name "msgbox" as a variable?
