Hello NG,

I have some problem using DInput... I wrote this code following the example 
from
Directx 9 SDK (December 2004/April 2005).

The problem is how to check the button status i.e. in this piece of code:

        for( int i = 0; i < LAST_BTN; i++ )
        {
                if( js.rgbButtons[GEARUP_BTN] & 0x80 )
                        Gear++;
                else if( js.rgbButtons[GEARDOWN_BTN] & 0x80 )
                        Gear--;
                else if( js.rgbButtons[CHANGECAMERA_BTN] & 0x80 )
                        SWITCH_CAMERA( Camera );
                else if( js.rgbButtons[ARM_BTN] & 0x80 )
                        SWITCH_ARM( ArmStatus );
        }

after the first time I push one of the checked buttons the if statement is 
executed correctly
but after that each other check of the same button returns true even if the 
button have been
released. Why? How can I fix this?

HRESULT TfrmJoyState::UpdateInputState()
{
        HRESULT     hr;
        DIJOYSTATE2 js;

        if( NULL == g_pJoystick )
                return S_OK;

        hr = g_pJoystick->Poll();
        if( FAILED(hr) )
        {
                hr = g_pJoystick->Acquire();
                while( hr == DIERR_INPUTLOST )
                        hr = g_pJoystick->Acquire();

                return S_OK;
        }

        if( FAILED( hr = g_pJoystick->GetDeviceState( sizeof(DIJOYSTATE), 
&js ) ) )
                return hr;

        FSteering    = js.lX;
        FTrust         = js.lY;

        for( int i = 0; i < LAST_BTN; i++ )
        {
                if( js.rgbButtons[GEARUP_BTN] & 0x80 )
                        Gear++;
                else if( js.rgbButtons[GEARDOWN_BTN] & 0x80 )
                        Gear--;
                else if( js.rgbButtons[CHANGECAMERA_BTN] & 0x80 )
                        SWITCH_CAMERA( Camera );
                else if( js.rgbButtons[ARM_BTN] & 0x80 )
                        SWITCH_ARM( ArmStatus );
        }

        return S_OK;
}
