Simple, but useful classes to save/restore window appearance
<!-- Add the rest of your HTML here -->


Now you can use simple classes CWindowSettings, CReBarSettings, CSplitterSettings with your WTL projects to quickly save/restore window appearance (size, position). Settings are saved in registry. Additional properties saved for ReBar Control including bands sequence and position. So your window will appear next time when opened as user customized him.

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

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

    Also you can save/restore splitter position using CSplitterSettings class

I mentionned in a previous message, I suggest using GetWindowPlacement and SetWindowPlacement as it will properly save the current state including the restored size if the window is maximized or minimized and it will also save the "restore to maximized" flag properly so that you or the user ca restore a minimized window to the previous state.
Generally it is good to have a minimum of validation to ensure that the window will be (at least partially) visible if the user changes its screen resolution (or edit the registry).
For application windows, if "start maximized" or "start minimized" was specified, it should have priority over saved settings. Also, if the window was saved minimized, you may want to start it to its last non-minimized state (You may call ShowWindow after SetWindowPlacement for that).
