My D3DApp has the following problem:-

Direct3D8: (ERROR) :GetTransform does not work in pure-device

What does this mean ?

Don't create a device with D3DCREATE_PUREDEVICE if you're going to use
GetTransform.

It means you created a Pure Device (probably done for you if you use the
sample framework). When this is done, D3D can't retreive the transform
(what you are essentially asking D3D to do when you call GetTransform() ).
You have two options, either:

a) Don't create a pure device. You probably don't need to unless your app
needs the absolute fastest FPS. With most apps, you won't see a difference
in FPS at all.

b) Store the transform instead of asking D3D for it. Since you are setting
it initially, you already have. Just hang on to it and use it where you are
calling GetTransform().

Good luck.
