Save Printer Settings

The entirety of the PrinterSettings – including vendor specific options – can be stored by persisting the HDEVMODE structure received via PrinterSettings.GetHdevmode(), then restored via PrinterSettings.SetHdevmode(IntPtr).

The class below will add two extension methods to save and restore PrinterSettings to and from a byte array.

Caveat programmer: some printer drivers do not have backwards or forwards compatibility, and may crash if using persisted data from another version or architecture of the driver.

Example Use:

PrinterSettings CurrentSettings;
const string myAppKeyName = @"Software\MyApplicationName";
const string printerSettingValueName = "PrinterSettings"

// save
using (var sk = Registry.CurrentUser.CreateSubKey(myAppKeyName))
{
    sk.SetValue(printerSettingValueName, this.CurrentSettings.GetDevModeData(), RegistryValueKind.Binary);
}

// restore
using (var sk = Registry.CurrentUser.CreateSubKey(myAppKeyName))
{
    var data = sk.GetValue(printerSettingValueName, RegistryValueKind.Binary) as byte[];

    this.CurrentSettings = new PrinterSettings();
    if (data != null)
    {
        this.CurrentSettings.SetDevModeData(data);
    }
}

Non-closable window

Creates a WPF Window that has no "x" button.

<win32:NonClosableWindow x:Class="Example Window"
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
    xmlns:win32="clr-namespace:Esatto.Win32.Wpf;assembly=Esatto.Win32.CommonControls"
    xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006" mc:Ignorable="d"
    xmlns:d="http://schemas.microsoft.com/expression/blend/2008" 
    CanClose="{Binding Path=CanClose}"
    Title="Task Progress" ResizeMode="NoResize" SizeToContent="WidthAndHeight">
    <Grid>
    </Grid>
</win32:NonClosableWindow>

Watch for windows created from a specific process

this.WindowCreatedHook = new WinEventHook(this.FrameworkProcess, null, WinEvent.EVENT_OBJECT_SHOW, WinEvent.EVENT_OBJECT_HIDE, syncCtx: Sync);
this.WindowCreatedHook
    .Where(c => c.WinObject == WinObject.OBJID_WINDOW && c.WinChild == WinChild.CHILDID_SELF)
    .Subscribe(Hook_EventReceived);
    
private void Hook_EventReceived(WinEventEventArgs args)
{
    Console.WriteLine(args);
}

Create a "docked" window to some other process

var DockTarget = new Win32Window(0x12345678 /* Target HWND */)
this.LocationMonitor = new WindowLocationMonitor(DockTarget, DockTarget.GetParent());
this.LocationMonitor.WindowMoved += (_, e) => this.Location = Point.Add(e.WindowRect.Location.ToGdi(), DockTargetPositionOffset);
this.LocationMonitor.DragBegin += (_, _) => this.Hide();
this.LocationMonitor.DragEnd += (_, _) => this.Show();
this.LocationMonitor.Exception += (_, e) => Console.WriteLine("Exception on window location monitor: {0}", e.ExceptionObject);
this.Show();

Show Excel, Word, and other shell Preview handlers as a control

Add ShellPreviewControl to a Windows Form or WPF Window. Set DisplayedPath to an absolute path.

Create an "Open With" menu

var assocs = AssociatedHandler.ForPath(tempPath);
var cxm = new ContextMenu(
    assocs.Select(at => new MenuItem(at.DisplayName, (_1, _2) => at.Invoke())).ToArray());
cxm.Show(this, this.PointToClient(MousePosition));

Find and manipulate HWNDs

var foregroundCaption = Win32Window.GetForegrundWindow().CachedName;
var window = Win32Window.Find(process, w => w.CachedClass == "Example"" && window.GetIsShown());
var child = window.FindChild(ww => ww.CachedClass == FrameworkConstants.MdiClientClass);
child.Show();

Persist window location to registry

Create a window which when it opens will restore to the same location. Avoids restore if the window get's resized to be very small, or if monitor changes put it mostly outside of the desktop viewport. Restores maximized if the window is closed when maximized. Persists the restored size, and never restores minimized.

<Window x:Class="RememberWindowLocation.MainWindow"
        xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
        xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
        xmlns:win32="clr-namespace:Esatto.Win32.Wpf;assembly=Esatto.Win32.CommonControls"
        Title="MainWindow" Height="450" Width="800"
        win32:WindowPlacement.SavePath="Software\DemoApp\WindowPos">
</Window>
