Your rude post does NOT answer the OP's question.
hi Dougie, I don't see any reason for condescension or a patronizing tone. My intend was not to be rude; my intent was to help the OP help themselves. Often it is clear that a person does not make the slightest effort to find their own answer before posting a question (and often just a quick google search is what was needed).
We do not help people by answering ALL of their questions. Sometimes we help people the most by pointing them at the right tools, and by helping them help themselves; learning how to ask intelligent questions, and encouraging them to do a little of their own footwork first. Its just better, that's all... not rude.
