In the Stackoverflow FAQ:
Why are some questions closed?
Questions that are deemed sufficiently off-topic may be closed by the community. Users with 3000 reputation can cast a limited number of close votes per day. When a question reaches 5 close votes, it is marked as closed, and will no longer accept answers. Closed questions may be opened by casting reopen votes in the same manner. However, you may only vote to close or reopen a question once.
An explanation of common reasons to close questions is available on meta.
And although your question is still open you may want to reread your question and check it for spelling or grammar mistakes.
In some cases if you appear to be demanding an answer to your question, or for example asking why people aren't answering you, you may get a negative response. All things considered, you still may just have an ol' fashion terrible question that nobody is interested in.
We also don't need your permission to close your question, that's the value in a peer-moderated community.
Make sure you read this on meta, and maybe take a look there for your answer.
