The framework calls this member function when the current window gets raw input.

afx_msg void OnRawInput(
    UINT nInputCode,
    HRAWINPUT hRawInput



[in] nInputCode

Input code that indicates whether the input occurred while the application was in the foreground or not. In either case, the application must call CWnd::DefWindowProc so the system can perform cleanup.

This parameter can be one of the following values:

  • RIM_INPUT - Input occurred while the application was in the foreground.

  • RIM_INPUTSINK - Input occurred while the application was not in the foreground.

[in] hRawInput

Handle to a RAWINPUT structure that contains the raw input from the device.

This method receives the WM_INPUT notification, which is described in the Windows SDK.


This member function is called by the framework to allow your application to handle a Windows message. The parameters passed to your function reflect the parameters received by the framework when the message was received. If you call the base-class implementation of this function, that implementation will use the parameters originally passed with the message and not the parameters you supply to the function.

This method is supported in Windows Vista and later.

Additional requirements for this method are described in Build Requirements for Windows Vista Common Controls.
