How to create random number generator with ascending numbers and without duplicates?

How to create a generator which will generate random numbers 1-39 with no duplicate numbers and numbers should be ascending...

Thanks for your reply. Does that work with Text field -sprites too? Now there was text area but what If I put couple of Text fields and Button to generate numbers in fields...does that work same way?

Hi, the text box is there purely for testing purposes. If you understand how my example works you understand that the important part is the number generation event. You can trigger the number generation events anyway you want and then use the numbers any way you want from the array, it does not matter whether you trigger the number generation with a button or print the generated numbers out in text or sprite font objects or use them in some other way.
