Problem with GUI

[rohan22]

heu guys i am new to this.i created my first gui for arduino uno..but i don't know how to save it permanently as a".exe" file. and bigger issue iis..after somtimes it stops responding.sorry for bad English
here is diialog code.
.```

thank you guys for helping me!!!!

Hi,

What do you mean by "save it permanently as an exe" ? If you can run your application then it's already an executable.

As for your bug, you should run a debug build and break when you see it's getting locked.

Note that you are also not checking whether the serial port opening is successful.

when i am building program in release mode it is not showing any error but in debug mode t is showing error with <QSerialPort> header file

[SGaist]

What exact error are you getting ?
