No, there are not different or many more constants as the defined constants are Or'ed together to produce added values.

For ex. if constant WS_EX_CUSTOM1 = 1 and WS_EX_CUSTOM2 = 2 when you Or them together for a value designating the two separate propertys you get a value of 3. There will be no constant defined for 3 so Windows can reverse the process and determine that 3 = WS_EX_CUSTOM1 and WS_EX_CUSTOM2.
