Raw input functions on windows wouldnt compile| jcylam (104) |  |
| Ok I'm new to programming in c++ and i need help on working with raw functions in windows for this function: http://msdn.microsoft.com/en-us/library/ms645600(VS.85).aspx i cannot get it to compile without seeing see declaration of blah blah blah. I clicked and i looked, and its not helpful at all. nor is the MS website. Can you help me? an example would be great eg for a mouse or something. THANKSSSS | |

| #pragma once #include "stdafx.h" void register_device () { USHORT usUsagePage = 0; USHORT usUsage = 0; DWORD dwFlags = RIDEV_INPUTSINK; HWND hwndTarget; typedef struct tagRAWINPUTDEVICE { //Defines information for the raw input device USHORT usUsagePage; /*Top level collection Usage page for the raw input device*/ USHORT usUsage; /*Top level collection Usage for the raw input device*/ DWORD dwFlags; /*Mode flag that specifies how to interpret the information provided by usUsagePage and usUsage*/ HWND hwndTarget; //Handle to the target window } RAWINPUTDEVICE, *PRAWINPUTDEVICE, *LPRAWINPUTDEVICE; BOOL RegisterRawInputDevices ( //Registers the devices that supply the raw input data PCRAWINPUTDEVICE pRawInputDevices, /*Pointer to an array of RAWINPUTDEVICE structure that represent the devices that supply the raw input*/ UINT uiNumDevices, /*Number of RAWINPUTDEVICE structures pointed to by pRawInputDevices*/ UINT cbSize ); //Size, in bytes, of a RAWINPUTDEVICE structure if (RegisterRawInputDevices <= 0) { cout << GetLastError (); //Print out error if occurred } UINT GetRawInputDeviceList ( //Enumerates the raw input devices attached to the system PRAWINPUTDEVICELIST pRawInputDeviceList, /*Pointer tp buffer that holds an array of RAWINPUTDEVICELIST structures for the devices attached to the system*/ PUINT puiNumDevices, //Pointer to a variable UINT cbSize ); /*Size of a RAWINPUTDEVICELIST structure*/ UINT GetRawInputDeviceInfo ( /*Gets information about the raw input device*/ HANDLE hDevice, //Handle to the raw input device UINT uiCommand, //Specifies what data will be returned in pData LPVOID pData, /*Pointer to a buffer that contains the information specified by uiCommand*/ PUINT pcbSize ); /*Pointer to a variable that contains the size, in bytes, of the data in pData*/ UINT GetRegisteredRawInputDevices ( /*Gets information about the raw input devices for the current application*/ PRAWINPUTDEVICE pRawInputDevices, /*Pointer tp an array pf RAWINPUTDEVICE structures for the application*/ PUINT puiNumDevices, /*Number of RAWINPUTDEVICE structure in *pRawInputDevices*/ UINT cbSize ); //Size, in bytes, of a RAWINPUTDEVICE structure } Ok this the layout format that i have written so far by looking at the msdn website. Can you guys help me out by pointing out the problems of how to fix it. Thanks so much | |
