Manager.GetDevices (DirectX?)
lazarus / 34-Windows

I want to use Manager.GetDevices to get a list of pointing devices
(mice, trackpads etc) on a Windows machine.

I've looked at MSDN (https://msdn.microsoft.com/en-
us/library/windows/desktop/bb153253(v=vs.85).aspx) but I can't figure
out how to instantiate an instance of Manager to get at the GetDevices
function.

I'm guessing that this will just be my first stumbling block,
especially as once I have that list I want to be able to disable and
enable these devices... but just getting access to that Manager[/tt/
object would be a good start - if, indeed, that is the best way to get
access to these devices from Lazarus/FPC.

Thanks,

FM

Hi, acording to microsoft https://msdn.microsoft.com/en-
us/library/windows/desktop/ms835107.aspx
This function is part of DirectX implementation. So you need include
in your program DirectX headers.
Here is some information about DirectX and freepascal/lazarus

I spotted that reference and wondered if that was the case...

I've included the files that seem relevant (DirectInput.pas,
DirectX.inc, DXTypes.pas, Jedi.inc, Xinput.pas - some of which may not
actually be needed, I'll play with dependencies if/once I get things
working), but I guess I still need to create the Manager object and I
can't figure that out...

(Or does anyone know of a way of getting this info without DirectX?)

It looks like those fpc DirectX libraries don't contain the same
functions and things that the MSDN example I linked to requires.

So I've hit a complete dead end right now.

Is there any other way to do this?

I'm getting somewhere now without using DirectX.. I'll start another
thread that is more relevant.
