How to use these classes in your WTL App

1. Add two files RegSettings.h and RegSettings.cpp to your project.
2. Add the header file RegSettings.h to the Frame or Window source code that will be using the classes.
3. Load window settings from registry by adding the following code to the method that shows the window (the global Run function for a main frame):

   CWindowSettings ws;
   if(ws.Load("Software\\WTLApps\\DemoApp", "MainFrame"))
      ws.ApplyTo(wndMain, nCmdShow);
   else
      wndMain.ShowWindow(nCmdShow);
   

4. Load rebar settings from registry by adding the following code to the OnCreate method of the frame class:

   CReBarSettings rs;
   CReBarCtrl rbc = m_hWndToolBar;
   if(rs.Load("Software\\WTLApps\\DemoApp", "ReBar"))
     rs.ApplyTo(rbc);
   

5. Save window and rebar settings to registry by adding the following code to the OnDestroy method of the frame class:

   CWindowSettings ws;
   ws.GetFrom(*this);
   ws.Save("Software\\WTLApps\\DemoApp", "MainFrame");
   
   CReBarSettings rs;
   CReBarCtrl rbc = m_hWndToolBar;
   rs.GetFrom(rbc);
   rs.Save("Software\\WTLApps\\DemoApp", "ReBar");
