Schengen Visa to France Help

Hi Friends,

I am a 28 year old guy from Sri Lanka. I have applied for schengen visa to France on 2012 May (Right after the completion of my Bachelors Degree) tourist visa to visit my uncle in France. Even though I provided all the required documents my visa was rejected (Stamped passport) saying The intention to leave schengen territory before expiration of visa has not been proved. This can mainly because I did not have a job and it was just after my degree. My uncle advised me to apply again with his letter to visa officer within a month. So I applied again in 2012 June but got rejected again (Silly me!)
Now I am going to apply again saying I am sponsoring for everything and my uncle is only going to provide lodging. This time I am going to apply with my parents. Now I am working as a Senior Engineer in a reputable company with a high grade salary and I have more than enough money in my account to finance for three people. My father is also working as a Deputy Manager at a bank and my mother has retired. My father owns two houses and a vehicle. I am also currently following an MBA and I got the letter from university saying they approve leave. Also I am going to get married on July 2015, so I am going to attach copies of my wedding related bills as proof. My brother is not going on this trip because he is still studying in the university for his Bachelors. I am going to provide all the required documents alongside with the docs I have mentioned above with my uncle's salary and bank details even though he is not sponsoring. Do you think me and my family have a chance of getting visa this time? I am worried of my previous refusals. Also please note that I have traveled previously to Thailand and Singapore for personal visits and to South Africa for business purpose. But my parents have not traveled outside the country before.

Please help me
