It is not clear (or wasn't to me) how to use QT4 with Visual Studio. The key to the problem is that you need to re-compile QT4 for Visual Studio. If you are not using MingGW at all then you can do all this in the original QT directory. Otherwise copy the entire c:\qt\2009.03 directory to something like c:\qt\2009.03_vs2008
Open a VS command line prompt so that all the env vars are set up.
Run the configure script, my suggestion is:
C:\Qt\2009.03\qt>configure -no-qt3support -no-opengl -platform win32-msvc2005 -no-libtiff -no-dbus -no-phonon -no-phonon-backend -opensource -debug-and-release
Let it do it's thing
Then type nmake to build the VS libraries
Notes:
Use nmake confclean to clean the directory before running a new configure cmd
