I need to generate n random varibales with Beta Distribution with specified mean, variance, meninmum and maximum limit. I would be thankful if you can help me.

You write you want to generate random numbers with specified mean and variance.
Mean and variance are functions of alpha and beta:
https://en.wikipedia.org/wiki/Beta_distribution
So solve these relations E[X]=f(alpha,beta), Var[X]=g(alpha,beta) for alpha and beta.

The difficulty with the above is that Wikipedia only deals with the case of x ~ [0, 1] or x ~ (0,1) rather than a more generalized range.
