DetectDevices

Detects disks on your computer. It is called automatically when the library is loaded.

BOOL DetectDevices();
Return values
If there are no errors, the function returns a nonzero value.
If some errors occur, the function returns a zero value. Call GetLastErrorDll to get detailed information about the error.
Comments

When the library is loaded, the code of this function is executed automatically, so you do not have to call it right after the library is loaded. When the application window gets the WM_DEVICECHANGED system message, you should call the DeviceChange function from the SDK and it will call DetectDevices if necessary.

DeviceChange

DeviceChange

Processes the WM_DEVICECHANGE system message.

BOOL DeviceChange(
  WPARAM nEventType,
  LPARAM dwData
);
Parameters
nEventType
[in] The wParam value of the WM_DEVICECHANGE system message.
dwData
[in] The lParam value of the WM_DEVICECHANGE system message.
Return values
If the configuration of disks in the system has changed, the function returns a nonzero value.
If the configuration of disks has not changed, the function returns a zero value.
Comments
During the work of your application disks and partitions can appear and disappear many times. When such events occur, the system sends the WM_DEVICECHANGE message to all applications that have open windows at the moment. When your application receives such a message, it should inform the Disk Password Protection library that there are some changes in the disk structure of the system. To do it, you should receive the WM_DEVICECHANGE message in the message handler and call the DeviceChange function from the SDK when it is received.
Below you can see examples of processing the WM_DEVICECHANGE message in applications. 

...
ON_MESSAGE( WM_DEVICECHANGE, OnDeviceChange)
...
LRESULT CMyDlg::OnDeviceChange( WPARAM nEventType, LPARAM dwData )
{
	if ( DeviceChange( nEventType, dwData ) )
	{
	...
	}
}
 


protected override void WndProc(ref Message m)
{
	if ( DiskPP.DeviceChange( ref m ) )
	{
	...
	}
	base.WndProc (ref m);
}
