I have just asked this http://goo.gl/bo4O5T question, and it yelled at me to include something i have already tried, i googled 10 mins how to do this, with no answer, so i asked on SO, but do i HAVE TO write something like "i have already tried this and that"?

I mean, of course i have tried to solve it mysleft, but everything went to compile errors, i guess nobody needs to know that, or that i googled it 10 mins.

So is it really nesserely to say "i have already tried XXX", i mean i **had** to write it and then i removed it by edit, any thoughts?
