Direct3D9: (ERROR) :ResetEx failed and ResetEx/TestCooperativeLevel/Release are the only legal APIs to be called subsequently[/quote]

But I'm not using a IDirect3DDevice9Ex::ResetEx, why 'ResetEx' came out? I have tested both versions of 'DXSDK June 2010' and 'DXSDK April 2007', the output texts are same. Even though, the interface of IDirect3DDevice9Ex was not included in DXSDK April 2007, but it came out anyway! That's weird, can this caused by my system version? I'm using windows7 64-bit.

What I expect is this:

I just wonder how to enable the D3D creation stack trace when resource leak on device reset? I have set EnableCreationStack to 1 in system registry, that can't solve this.

Thanks for any help.

Not a direct answer to your specific questions, but if you're wondering which resource has leaked, there's a very high likelihood that you've created some D3DX objects (Sprite, Font or Effect are the most likely) but haven't called OnLostDevice on them. You'll need to call OnResetDevice when the device is back too.
