How create device without window?

When I set this parameter as null, is throwing exception "Error in the application". Why?

In MSDN -

renderWindowHandleSystem.IntPtr
Handle to a Form, Panel, or any other Control derived class. This parameter indicates the surface to bind to the device.

For full-screen mode, the window specified must be a top-level window.

For windowed mode, this parameter can be null. If null is specified, a non-null handle must be specified when calling Device.Present. This can be done either by setting the PresentParameters.DeviceWindow property, or by using the optional param_Control_overrideWindow parameter of the Device.Present method.

The simple answer is that you cannot do this...

I once try to do that for a Filter that was suppose to run in a DLL

And basicly you will need a Handle to an existing window

You can create a very basic window that will open briefly

or hide a Edit on a form and use this hiden window to get a Handle

This might be a bug in the Managed DX layer... But you're gonna need a window handle sooner or later... Why not pass it sooner?
