MFC: How to change default application look

gistfile1.cpp

//When using MFC wizard to generate a project, it will ask developer to choose an application look style. 
//Say we have chosen "Office 2007 Blue" as default and want to change it into "Windows 7". Here is how to:

//1. In MainFrm.cpp, we will see:

CMainFrame::CMainFrame()
{
	// TODO: add member initialization code here
	theApp.m_nAppLook = theApp.GetInt(_T("ApplicationLook"), ID_VIEW_APPLOOK_OFF_2007_BLUE);
}

//Replace ID_VIEW_APPLOOK_OFF_2007_BLUE with ID_VIEW_APPLOOK_WINDOWS_7 or whatever you want.

//2. We may see nothing changed if the application has launched before. 
//This is because that MFC application stores settings in Windows's registry. 
//Go regedit and delete \HKEY_CURRENT_USER\Software\[Company Name]\[Application Name]. 
//Or modify \HKEY_CURRENT_USER\Software\[Company Name]\[Application Name]\Workspace\ApplicationLook.
//[Company Name] is default to "Local AppWizard-Generated Applications".
