VS 2010 need to write lines of output depending on number of lines entered from input box

I have a input box asking what to write and another seperate input box asking how many times to write the text. I am new to VB 2010 and wondering how to write a loop statement for this.

So 1st input box asks: what to write? I answer 'Merry Xmas'
the 2nd input box asks: how many times to write it? I answer '10'

need help to understand loops.

Thanks
