copied!<p>I finally came up with a Form subclass that solves this, once and for all. To use it:</p> <ol> <li>Inherit from RestorableForm instead of Form.</li> <li>Add a binding in (ApplicationSettings) -> (PropertyBinding) to WindowRestoreState.</li> <li>Call Properties.Settings.Default.Save() when the window is about to close.</li> </ol> <p>Now window position and state will be remembered between sessions. Following the suggestions from other posters below, I included a function ConstrainToScreen that makes sure the window fits nicely on the available displays when restoring itself.</p> <h3>Code</h3> <pre><code>// Consider this code public domain. If you want, you can even tell // your boss, attractive women, or the other guy in your cube that // you wrote it. Enjoy! using System; using System.Windows.Forms; using System.ComponentModel; using System.Drawing; namespace Utilities { public class RestorableForm : Form, INotifyPropertyChanged { // We invoke this event when the binding needs to be updated. public event PropertyChangedEventHandler PropertyChanged; // This stores the last window position and state private WindowRestoreStateInfo windowRestoreState; // Now we define the property that we will bind to our settings. [Browsable(false)] // Don't show it in the Properties list [SettingsBindable(true)] // But do enable binding to settings public WindowRestoreStateInfo WindowRestoreState { get { return windowRestoreState; } set { windowRestoreState = value; if (PropertyChanged != null) { // If anybody's listening, let them know the // binding needs to be updated: PropertyChanged(this, new PropertyChangedEventArgs("WindowRestoreState")); } } } protected override void OnClosing(CancelEventArgs e) { WindowRestoreState = new WindowRestoreStateInfo(); WindowRestoreState.Bounds = WindowState == FormWindowState.Normal ? Bounds : RestoreBounds; WindowRestoreState.WindowState = WindowState; base.OnClosing(e); } protected override void OnLoad(EventArgs e) { base.OnLoad(e); if (WindowRestoreState != null) { Bounds = ConstrainToScreen(WindowRestoreState.Bounds); WindowState = WindowRestoreState.WindowState; } } // This helper class stores both position and state. // That way, we only have to set one binding. public class WindowRestoreStateInfo { Rectangle bounds; public Rectangle Bounds { get { return bounds; } set { bounds = value; } } FormWindowState windowState; public FormWindowState WindowState { get { return windowState; } set { windowState = value; } } } private Rectangle ConstrainToScreen(Rectangle bounds) { Screen screen = Screen.FromRectangle(WindowRestoreState.Bounds); Rectangle workingArea = screen.WorkingArea; int width = Math.Min(bounds.Width, workingArea.Width); int height = Math.Min(bounds.Height, workingArea.Height); // mmm....minimax int left = Math.Min(workingArea.Right - width, Math.Max(bounds.Left, workingArea.Left)); int top = Math.Min(workingArea.Bottom - height, Math.Max(bounds.Top, workingArea.Top)); return new Rectangle(left, top, width, height); } } } </code></pre> <h3>Settings Bindings References</h3> <ul> <li><a href="http://msdn.microsoft.com/en-us/library/system.componentmodel.settingsbindableattribute.aspx" rel="noreferrer">SettingsBindableAttribute</a></li> <li><a href="http://msdn.microsoft.com/en-us/library/system.componentmodel.inotifypropertychanged.aspx" rel="noreferrer">INotifyPropertyChanged</a></li> </ul>
