[Qt-interest] Including Win32 SDK header and Lib dir to my project?

[Huan "KDE Zealot" Truong]

Thanks for the comment, Karol.

Actually I needed to call API functions RegisterDeviceNotification and
UnregisterDeviceNotification (as defined in windows.h) to check if
there is a USB flash drive plugged into the system.

Now the only two errors I had were from link.exe complaining about not
being able to resolve those functions.

mainwindow.obj : error LNK2019: unresolved external symbol
__imp__UnregisterDeviceNotification at 4 referenced in function "public:
virtual __thiscall Window::~Window(void)" (??1Window@@UAE at XZ)
mainwindow.obj : error LNK2019: unresolved external symbol
__imp__RegisterDeviceNotificationW at 12 referenced in function "private:
bool __thiscall Window::doRegisterForDevNotification(void)"

Looks like for some reason the functions didn't get defined. I am
using MS VC Express 2008 with Windows SDK 6.0A. I tried to add:

DEFINES         += WINVER=0x0501 _WIN32_WINNT=0x0501 _MSC_VER=900

to my .pro file.

So my makefile has:
DEFINES       = -DUNICODE -DWIN32 -DQT_LARGEFILE_SUPPORT
-DWINVER=0x0501 -D_WIN32_WINNT=0x0501 -D_MSC_VER=900 -DQT_DLL
-DQT_XML_LIB -DQT_GUI_LIB -DQT_NETWORK_LIB -DQT_CORE_LIB
-DQT_THREAD_SUPPORT

It didn't resolve the problem. Anyone has any idea?

Thanks,

- Huan T.
