Thread: [win32] - how use joystick?

i understand how can i activate the joystick:

Code:

joySetCapture(inst->hWnd(),JOYSTICKID1,100,true);
                    joySetCapture(inst->hWnd(),JOYSTICKID2,100,true);

but i see 1 problem: i must activate for all connected joysticks, but how can i get the number of connected joysticks?
and then i must release the joystick(when i don't need it):

Code:

joyReleaseCapture(JOYSTICKID1);
                    joyReleaseCapture(JOYSTICKID2);

i activate the joystick, when the form is created, but i think that isn't the right way to do, because the user can connect the joystick when want's.
please anyone tell me something.
