Hi everyone, HungVB.Com will share a trick to generate a random string or random number, like a barcode :D
Here, I only write string or numeric constructors, not complete the tools for everyone to apply to create more new and better tricks.
Code String constructor : https://notepad.vn/fxS87N143
Code Random number generator. : https://notepad.vn/GTmuipD38
With the above two functions, you can customize according to your ability.
Good Luck For You.
