Creating Library using QTCreator (hiddevice)

[AlphaWolfXV]

Hello all,
I am working with QT Creator 1.2.1 on Windows Vista 32bit and I would like to create a library file fora hiddevice class. I have the project set up as below... Basically I created these cpp/h files for using an hiddevice with QT and the files work fine when included in a project and utilized. Now I thought that I should put them into a ".a" file or a ".dll" file and just reference the library in the pro file of a project, negating the need to "#include <hiddevice.h>" in my project. When I build the Library project, it completes fine. When I load the libary in the other project to use, I get issues with "DWORD not naming a type" and others like it. Obviously the library was created incorrectly or my linking process is skewed. If anyone has some light they can shed on library creation with QTCreator or perhaps a better way to go about implementing what I am after, please advise!!
Thanks as always,
AlphaWolfXV
