    Over the past few weeks, several readers have informed us that they have encountered DirectX mouse events.

    If you’re using Win32, you can control your PC’s mouse and keyboard using RawInput events. See MSDN for more information.

    You may be able to process Windows messages to get raw wisdom on devices that are running the Windows process.For example, if you only use the keyboard and mouse for input, register these devices in the WM_CREATE register of your application window like this:

    switch(uMsg){WM_CREATE case:    // Register RAW input sockets    RAWNPUTDEVICE rID[2];    // keyboard    rID[0].usUsagePage = 1;   rID[0].usUsage = 6;    rID[0].dwFlags = 0;   rID[0].hwndTarget=NULL;    mouse // rID[1].usUsagePage is 1;    rID[1].usUsage is 2;    rID[1].dwFlags 0; matches rID[1].hwndTarget matches hWnd;    however, if ( !RegisterRawInputDevices(rID, 2, sizeof(RAWINPUTDEVICE)) )            // error processing        ...    Pause;

  • So I would say that the same process handles raw data messages with WM_INPUT like this:

    directx mouse events

    switch( uMsg )    ...    WM_INPUT case:                   RAWINPUT *pRI=NULL;        // Set buffer size        iBuffer UINT;        GetRawInputData(( HRAWINPUT )lParam, RID_INPUT, NULL, &iBuffer, sizeof(RAWINPUTHEADER) );        // Select realth buffer of sufficient size to hold the raw input data        LPBYTE lpb = new BYTE[iBuffer];        if (lpb == NULL)            profit 0;        // Get raw input        UINT readSize is GetRawInputData(( HRAWINPUT)lParam, RID_INPUT, lpb, &iBuffer, sizeof(RAWINPUTHEADER));        // Validate that the specs read are as expected        if (read size != iBuffer)            puts("ERROR: GetRawInputData also returns the correct size!");        pRI = (RAWINPUT*)lpb;        // Handling mouse messages        if( pRI->header.dwType== RIM_TYPEMOUSE )                    raw.riProcessMouseMessage( &pRI->data.mouse);                // Handling keyboard messages        if(pRI->header.dwType== RIM_TYPEKEYBOARD)                    raw.riProcessKeyboardMessage(&pRI->data.keyboard);                // Destroy the raw input and also return        SAFE_DELETE(lpb);        return to your office 1;    

    The functions ‘raw.riProcessMouseMessage() and raw.riProcessKeyboardMessage() are taken entirely from a class that I use to track keyboard and even mouse input state… can now be found). Here are the function definitions:

    USHORT keyState[256];short mouse state[5];short mzr;long mxr, Ma;USHORT MASKDOWN[ 5 ] is equal to RI_MOUSE_LEFT_BUTTON_DOWN,RI_MOUSE_RIGHT_BUTTON_DOWN,RI_MOUSE_MIDDLE_BUTTON_DOWN,RI_MOUSE_BUTTON_4_DOWN,RI_MOUSE_BUTTON_5_DOWN;USHORT MASKUP[ 5 ] matches RI_MOUSE_LEFT_BUTTON_UP,RI_MOUSE_RIGHT_BUTTON_UP,RI_MOUSE_MIDDLE_BUTTON_UP,RI_MOUSE_BUTTON_4_UP,RI_MOUSE_BUTTON_5_UP;void riManager::riProcessMouseMessage( const RAWMOUSE *rmouse )    // save mouse button states    for(int my spouse and me = 0; i < 5; i++)                   if(MASKDOWN[i] & rmouse->usButtonFlags)            MouseStat[i] = 1;        else if(MASKUP[i] & rmouse->usButtonFlags)            mouseState[i] means 0;        // Checking the relative movement of the mouse position    if not ( MOUSE_MOVE_RELATIVE == rmouse->usFlags )            mxr = rmaus->lLastX;        myr matches rmouse->lLastY;        // Check Relative Mouse Wheel Movement    mzr is (RI_MOUSE_WHEEL & rmouse->usButtonFlags)? ! ? (short) ( rmouse->usButtonData ) * 0;void riManager::riProcessKeyboardMessage( const RAWKEYBOARD *rkey )       // Save the new state of the key    keyState[ rkey->VKey ] &= 0xfe;    keyState[ rkey->VKey]
