To solve the com port “Access is denied” problem of Arduino IDE

When I try to upload my code to 3D pinrter (Renkforce RF100 XL), I met the fatal problem

avrdude: ser_open(): can’t open device “\\.\COM5”: Access is denied.

The cause of this problem is very simple that I have already open a cura software which is connected to the 3D printer. Really stupid mistake.
