This function writes to a TXT file, The question of writing in just one look or skip line by line comes from the writeline or write function, thus: Writeline = write by jumping a line. write = write in the same beautiful.

Do this:

wr.Write("linha");
wr.Write("mesma linha");
wr.Close();

I hope it helps.
