This is not recommended. Stack Overflow is not your personal debugging service. Ideally you should narrow your problem down to a simple, isolated section of code. Something we could try for ourselves without having to wade through your entire project. This also means that if you have a large project, you should not include all your sources within your post. Keep it small.
And please don't "hide" your code in a zip file which we have to download from somewhere. Your posts should be self-contained. Should the link to your zip-file ever go down, then your question is no longer valid and useful to others. We can after all no longer see the actual sources that you are having a problem with.
And as stated by @sixlettervariables, downloading zip files is not really something many like to do to begin with. You never know what you might drag onto your computer. (Malware, viruses, trojans, pictures of cats) So they are best avoided.
