.NET / Windows Forms: remember windows size and location

by

If you add this code to your FormClosing event handler:

if (WindowState == FormWindowState.Maximized)
{
    Properties.Settings.Default.Location = RestoreBounds.Location;
    Properties.Settings.Default.Size = RestoreBounds.Size;
    Properties.Settings.Default.Maximised = true;
    Properties.Settings.Default.Minimised = false;
}
else if (WindowState == FormWindowState.Normal)
{
    Properties.Settings.Default.Location = Location;
    Properties.Settings.Default.Size = Size;
    Properties.Settings.Default.Maximised = false;
    Properties.Settings.Default.Minimised = false;
}
else
{
    Properties.Settings.Default.Location = RestoreBounds.Location;
    Properties.Settings.Default.Size = RestoreBounds.Size;
    Properties.Settings.Default.Maximised = false;
    Properties.Settings.Default.Minimised = true;
}
Properties.Settings.Default.Save();

It will save the current state.

Then add this code to your form’s OnLoad handler:

if (Properties.Settings.Default.Maximised)
{
    Location = Properties.Settings.Default.Location;
    WindowState = FormWindowState.Maximized;
    Size = Properties.Settings.Default.Size;
}
else if (Properties.Settings.Default.Minimised)
{
    Location = Properties.Settings.Default.Location;
    WindowState = FormWindowState.Minimized;
    Size = Properties.Settings.Default.Size;
}
else
{
    Location = Properties.Settings.Default.Location;
    Size = Properties.Settings.Default.Size;
}

It will restore the last state.

It even remembers which monitor in a multi monitor set up the application was maximised to.
