Actually sir I told that I didn't work on any live project but I have worked on three projects those were not live in the company. My question is that Is any live project work compulsory of one year experience???Should I mention those dummy projects in my CV.
What did these 3 projects do ? If they are of comemercial / educational value, then yes you can mention them. If they were done just so you can hone your skills in programming language X and the end product is not used by anyone, then no. The project mentioned in the last statement is something like 'Calculator in VB'
IMHO, I don't see a problem with mentioning projects in the resume. If the projects are truely "dummy projects", its depth (and value) will come out in the interview, and the interviewer will dismiss it.
Why prematurely dismiss projects (when the pool of projects is small) ? Just be very open, and let the interviewer decide.... now, of course, many years from now, when you have lots more projects to choose from, then feel free to cull the list.
Also, as an addition to all of the above, be enthusiastic about your projects and in my opinion, you can learn more about technology/domain of your project(s) and discuss how you went about learning it.
Even if the project is simple or 'dummy' you can try to enhance it iteratively in various ways.
