How to post properly:

Create a new thread in 2-6 forums, which don't match your problem.
Give the threads a title, which explains your problem in a few words. For example: "I need help!"
Post your complete program code in the threads. Important: Don't use code tags! And don't say what your problem is! Simply post the code!
Ignore the first (right) solution from somebody, who did some effort and guessed from your code, what problem you have.
Instead make up your own (wrong) solution and ask in a post, if it would work. Do not try it yourself!
After finding out that your solution is wrong, take a look at the suggested solution and copy-paste it in your code.
Complain that the solution does not work. Then after getting response find out that you have to change "FooBar" to the function name you are using.
Thank the forum member, which helped you, by rating his post "I disapprove" (optionally with a comment like "Thanks. It works!").
Edit your first post to "problem solved". Additionally you can also request "delete this thread".
Three years later, when you have a similar problem, simply post in your old threads. You don't need to create new threads this way. Isn't this perfect?
