Usage Examples

Basic Usage

// Extract from imageres.dll
var shield = GraphicsExtensions.ExtractIconFromImageres(
    (int)ImageresIconID.Shield, 
    IconSize.Medium
);

// Extract from shell32.dll
var folder = GraphicsExtensions.ExtractIconFromShell32(
    (int)Shell32IconID.Folder, 
    IconSize.Large
);

// Extract from ieframe.dll
var browser = GraphicsExtensions.ExtractIconFromIeFrame(
    (int)IeFrameIconID.InternetExplorer, 
    IconSize.Medium
);

// Extract from network shell
var wifi = GraphicsExtensions.ExtractIconFromNetShell(
    (int)NetShellIconID.WirelessNetwork, 
    IconSize.ExtraLarge
);

With Krypton Controls

// Button with UAC shield
var shieldIcon = GraphicsExtensions.ExtractIconFromImageres(
    (int)ImageresIconID.Shield, 
    IconSize.Medium
);
if (shieldIcon != null)
{
    kryptonButton1.Values.Image = shieldIcon.ToBitmap();
    kryptonButton1.Values.Text = "Run as Administrator";
}

// Picture box with folder icon
var folderIcon = GraphicsExtensions.ExtractIconFromShell32(
    (int)Shell32IconID.FolderOpen, 
    IconSize.ExtraLarge
);
if (folderIcon != null)
{
    kryptonPictureBox1.Image = folderIcon.ToBitmap();
}

Key Features

Type Safety

  • All icon IDs are strongly typed enums
  • IntelliSense support with full XML documentation
  • Compile-time checking prevents invalid icon IDs

Comprehensive Coverage

  • 300+ imageres.dll icons (modern Windows icons)
  • 300+ shell32.dll icons (classic Windows icons)
  • 200+ ieframe.dll icons (Internet Explorer icons)
  • 100+ moricons.dll icons (miscellaneous icons)
  • 100+ compstui.dll icons (printer/device icons)
  • 60+ setupapi.dll icons (hardware/setup icons)
  • 40+ netshell.dll icons (network icons)

Size Flexibility

All methods support the IconSize enum:

  • Tiny (8x8)
  • ExtraSmall (16x16)
  • Small (20x20)
  • MediumSmall (24x24)
  • Medium (32x32) - default
  • Large (48x48)
  • ExtraLarge (64x64)
  • Jumbo (96x96)
  • ExtraJumbo (128x128)
  • Huge (256x256)

Access to Unlisted Icons

You can access any icon by index, even if not in the enum:

// Access shell32.dll icon at index 500
var icon = GraphicsExtensions.ExtractIconFromShell32(500, IconSize.Medium);

// Access any DLL directly
var customIcon = GraphicsExtensions.ExtractIcon(
    @"C:\Windows\System32\mydll.dll", 
    42, 
    largeIcon: true
);

Benefits

  1. No Embedded Resources - Use Windows system icons directly
  2. Consistent UI - Icons match the Windows version
  3. Automatic Scaling - Extract at any size
  4. Type Safe - Strongly typed enums prevent errors
  5. Well Documented - Full XML documentation for all icons
  6. Cross-Version - Works on all Windows versions (with appropriate DLL availability)
  7. Memory Efficient - Extract icons on demand
