> I have tried it but all I got was "Please don't post UNTESTED solution" or so.
When?
That is NOT a normal behavior.
Nobody ALWAYS have time to post tested code. We posted ideas, not code the readers of these ideas should transform the code to themselves.
Who is responsible for smooth application working?
Not me or you or anybody else. The author of the application is. So He/She must test even TESTED code just to be sure that this code will work for Him/Her in His/Her environment.
