);

Parameters

  • wParam
    [in] Specifies the device event. This parameter can be one of the values in the following table.

  • lParam
    [in] Pointer to a structure that contains event-specific data. Its format depends on the value of wParam. The following table shows possible values for this parameter.

Remarks

A container application that allows dynamic addition or removal of devices should process the WM_DEVICECHANGE message in its top-level window and forward the message to the control using the NotifyRedirectDeviceChange method. An example of a dynamic device change is when a redirected disk drive is added or removed while the system is running.

Header discodlg.h, mstsax.idl
Library Mstsax.lib
