   Check your return codes for errors, and report them including GLE/LE, your variable values, and the market. That way we would know that at least you are calling your code.

   Don't look at GLE/LE unless you have an error. Don't just silence the compiler, it is trying to help you.

   Looks like decompiled code.
   

   Decompiled code is stolen code. Either you are a thief, a fence, or the receiver of stolen (intellectual) property. Either way we will not be an accomplice after the fact to that theft.

   If you post decompiled code again, you will likely be banned.

   Don't tell us you found it on the 'net: if someone stole your bank details and uploaded them on to the internet, is it OK for everyone to use them because "someone uploaded it, I don't know why I can't use that"?
