question about textures

It can only be associated with one device when you create it, so no you can't use it with another device.

I know that this is an issue when you want to use multiple viewports (ie - a 3D modeler). There are ways around this, I *think* you can create multiple viewports with one device (don't quote me on that...). Otherwise, you will have to load all the textures to each device. The same thing has to be done if you re-create a device after it was lost. Hope that helps...

then is i posible to create two windows that display differnt things but use the same device (multitask safe)?

i never had to do this

Yes, I have never had to do this, so I can't be of much help... I think it involves rendering to a surface, having multiple PRESENT_PARAMETERS, and a few other things... I'm sure someone else in this forum would be a much better help than myself...

PS, the only tutorial I know of for this is for VB6 and DX8, but I'm sure the basic concepts are still the same... The site is:

DirectX4VB.com

Just scroll down to the "Quick Snippets section, there is a section in there dealing with Multiple Viewports...

Present allows you to present your backbuffer to any window. If you want a different sized backbuffer for a different sized window, or just want different present parameters you'll want swap chains. Look into CreateAdditionalSwapChain.

When using swapchains some things are a bit odd... you can ask a swapchain what it's backbuffer surface is (for use in SetRenderTarget()), but you can't query it's ZBuffer. As such, in your swapchain's presentparameters it's useless (and a waste of video memory) to use AutoDepthStencil... I'm surprised to see that problem still exists in DX9.

Swapchains and present to different windows are fine for single monitor (or single device multi-mon) situations. If you're hoping to display to a second window on a second monitor, you'll need to create a second device. On the second device you'll need to create it's own versions of textures, vertex buffers, etc.
