I had already done like that, but when I change the priority using SetPriorityClass it change it but not correctly!!!

For example, if the priority of a process created is IDLE and I change it into HIGH it sets the process priority to NORMAL!!!!!!!!!!

This is my problem!!!!

Under NT &Win2K, you have to have setpriv privilege to set priority above NORMAL. An ordinary user doens't have that privilege token.

.. I do have that privilege!!!!

The problem is that the priorities don't chenge correctly!!!
