DirectInput SetDataFormat error -


i want write program interacting joystick. using standard sdk example , dinput8.lib.

here's code. guid taken enumjoystickscallback function. throw away minimise chance of error.

lpdirectinput8          g_pdi = null; lpdirectinputdevice8    g_pjoystick = null;  hresult hr = directinput8create ( getmodulehandle( null ), directinput_version, iid_idirectinput8, (void**)&g_pdi, null );      guid  *guid_saitek = new _guid ;     guid_saitek->data1 = 0xa00dbd70;     guid_saitek->data2 = 0x7fb5;     guid_saitek->data3 = 0x11e3;     char tmp[8] = { 0x80, 0x3, 0x44, 0x45, 0x53, 0x54, 0x0, 0x0 };     memcpy(guid_saitek->data4, tmp, 8);      g_pdi->createdevice( *guid_saitek, &g_pjoystick, null );     hr = g_pjoystick->setdataformat( &c_dfdijoystick2 ) ;

program fails on string 

hr = g_pjoystick->setdataformat( &c_dfdijoystick2 );

hr returns 0x80070216 seems error_arithmetic_overflow.

&c_dfdijoystick instead of &c_dfdijoystick2 not too.

for mouse same...

lpdirectinput8          di = null; lpdirectinputdevice8    mouse = null; hresult hr = directinput8create(getmodulehandle( null ),  directinput_version, iid_idirectinput8,  (void**)&di, null); hr = di->createdevice( guid_sysmouse, &mouse, null ); hr = mouse->setdataformat( &c_dfdimouse ) ;

hr returns 0x80070216 again example application "joystick.exe" works no problem.

getcapabilities returns random stuff definately not true

  • embarcadero rad studio xe5/borland cpp builder 6 (both have same results)
  • directinput saitek rudder pedals/saitek x52 controllers (both crash program)
  • 32bit app
  • standard sdk example "joystick"

what wrong? error not match related directinput. device creates no errors work leads errors.

thanks!

update: setcooperativelevel function returns 0x80070006 error_invalid_handle

finally found out problem. lied here: &c_dfdijoystick2

for reason microsoft attached pre-defined structures not match anythig. &c_dfdimouse not match simple 3 button mouse. answer came sample code "custom format". have make new format structure each device because enumobjects function not make you, makes directinput quite inconvenient.
