excellent.
it works perfectly with my ps2 pad and my usb adapter

(and the interface is beautiful)

what is the difference with DirectInput programming (i mean directly use dinput.dll) ? no disadvantages ?

In case you don't know: Enumeration is used when you DON'T want to declare any
constants with a value, so having Enumeration/EndEnumeration above, while it
does work, is pointless -- like declaring a Global variable that isn't used globally.

I don't know exactly, i assumed it's easier to use the winmm.lib than the dinput.dll, but it's as you wish.
I noticed that the driver of my controller device (Saitek) use DirectX and the DINPUT.dll, so...

Yes PB i know that. I often do this way just to be able to 'fold' the constant declaration.

But i assume i should use the brackets ';{' and '};'

well, after some research, the main limitations are : only two joysticks, and no force feedback.
but it's perfect for what I need.

>only two joysticks

not only two joystick !
you can use up to 16 joysticks (i only have 2 joysticks so i have not tested but it's somewhere on the doc).
#JOYSTICKID1 and #JOYSTICKID2 are defined in the winmm.h but you can specify 3, 4, 5, and so on...

Code: Select all

joyGetPosEx

The joyGetPosEx function queries a joystick for its position and button status.

MMRESULT joyGetPosEx(
  UINT uJoyID,     
  LPJOYINFOEX pji  
);

Parameters

uJoyID

Identifier of the joystick to be queried. Valid values for uJoyID range from zero (JOYSTICKID1) to 15, except for Windows NT 4.0. For Windows NT 4.0, valid values are limited to JOYSTICKID1 and JOYSTICKID2.

>force feedback

You are surely true because i don't see anything about that in the winmm.

I thought it was only possible to capture 2 of the 16 max joysticks (but use anyone of them).
but I think you're right, the 2 joysticks limitation should be just with NT.
Only two joysticks too, I can't test :roll:

#JOYCAPS_HASZ = 1
#JOYCAPS_HASR = 2
#JOYCAPS_HASU = 4
#JOYCAPS_HASV = 8
#JOYCAPS_HASPOV = 16
#JOYCAPS_POV4DIR = 32
#JOYCAPS_POVCTS = 64

What do these all mean?

TIA

#JOYCAPS_HASZ = Does your controller have a 3rd axis
#JOYCAPS_HASR = Does your controller have a 4th axis
#JOYCAPS_HASU = Does your controller have a 5th axis
#JOYCAPS_HASV = Does your controller have a 6th axis
#JOYCAPS_HASPOV = Does your controller have a Point Of Vue
#JOYCAPS_POV4DIR = Does your Point Of Vue have 4 directions
#JOYCAPS_POVCTS = Does your Point Of Vue supports degrees
