It is dead right on topic. Read again, what this fellow asked. Nothing but basics, he cannot figure out. And what you do. Sending him to read something he probebly read even before he decided to try to write application.
Forum is full of references to that Wiki you are sending us to, but, it is not useful. Example shown there does not work. It is related to some old version of Feng Office, and in latest versions it does not work that way at all, because all system is changed.
I do not know how many volunteers you have, but I guess none, if that page is the only product of volunteer work.
Sure, I would like to help, but I cannot. Althrough I am an experienced developer, I cannot do anything without some documentation. I am not willing to guess things out. I expect you to provide some useful API docs (or at least working examples) so I can learn how to use it and then I would be able to contribute to make that documentation better.
What you are expecting is that users should hack around and investigate code to find out how things work and then to write documentation for you. That does not go that way.
I am sure, one of your developres can, in very short time, write simple but enough documentation about basics of developing for FengOffice that would realu make things going on.
What I can see is that this problem with documentation is not from yesterday, but goes on for years back. It is like you are deliberately denying request for documetnation so you can earn more money form sponsorships. It loks like you are forcing people to sponsor even basic options they need jsut because tehy cannot do changes on their own, simply because there si no documentation.
Here is plastic example. soemtime ago, I needed option. The only responce on my question was comment that I actually do not need that option. And, when I managed to hack around workable soltion, i got no responce for several request for help to do it properly, so it can be reused by others. I got not one simple clue how to do what I need, althrough I did show will to do learn and do it it by myself, and share my knowledge.
So, what kind of volunteering you ask for when you are not willing to help with bassic stuff people ask. This forum is full of unanswered questions, especialy when development is subject.
On first sight, FengOffice loks like dead project. There is no active user base. Forum is almost dead, documentation does not exist, almost every qestion ends up with your direct or indirect requests for sponsorship, and most of the questions stay not just unanswered, but without any response.
So, when you are providing so little to your userbase, how come you expect so much from them?

So, instead asking us to do your work, why dont you for change, at least try to help this fellow by answering questions he asked, becuase what he asks interests all of us, and that is not written in any documentation you provided.
