You might wonder why your problem hasn't been answered. It is obvious that you haven't use the code tag which make it very unfriendly to read your code. I recommend you to tag your code and post your error messages.
Here is the key of having a successful question: (if you follow this guide correctly, I am sure that many people will answer your question)
Describe your problem clearly and fully!
So you have a great title and you're ready to compose a post. Resist the temptation to copy and paste your code and as an afterthought say "It doesn't work". That's not a description of the problem. If you want help, you have to give us enough information to work with. Include at least all of the following in your description of the problem:
1) An overview of what your program does.
2) The result of your current code.
3) What you expected your code to do.
4) The contents of any input files (if appropriate)
This tells us what context your program is in so that we can offer alternative solutions. It tells us exactly what your code does so that we can more easily pinpoint the problem without performing tedious troubleshooting steps. Finally, it tells us what you wanted your code to do so that we can compare what it does with what you wanted it to do. Most of the time, a knowledgeable member can answer your question almost immediately using just this information.
Keep the code short and sweet!
As much as we don't care, people insist on posting pages and pages of irrelevant code. Keep the code as short as possible. If the code isn't short, make it short by cutting out as much irrelevant code as possible. Ideally, we expect you to write a small test program that exhibits the problem you're having.
The benefit of this is twofold. First, you might end up solving the problem yourself. Second, if you can't solve the problem yourself, there's less code that we have to look at and the problem is more likely to jump out at us.
Use code tags!
There are two ways to wrap code in code tags. The easiest way to do this is to select all of your code and then click the # button on the message editor. This will automatically wrap the selected text in code tags. Without code tags, all leading whitespace will be removed from the code, so nicely formatted code ends up having no indentation. This makes the code very hard to read and many members will refuse to help you because they can't read your code.
