// possible combinations of image and check margins.
internal ContextMenuStrip CreateCheckImageContextMenuStrip()
{
    // Create a new ContextMenuStrip control.
    ContextMenuStrip checkImageContextMenuStrip = new ContextMenuStrip();

    // check margin and an image margin.
    ToolStripMenuItem yesCheckYesImage = 
        new ToolStripMenuItem("Check, Image");
    yesCheckYesImage.Checked = true;
    yesCheckYesImage.Image = CreateSampleBitmap();

    // Create a ToolStripMenuItem with no
    // check margin and with an image margin.
    ToolStripMenuItem noCheckYesImage = 
        new ToolStripMenuItem("No Check, Image");
    noCheckYesImage.Checked = false;
    noCheckYesImage.Image = CreateSampleBitmap();

    // Create a ToolStripMenuItem with a
    // check margin and without an image margin.
    ToolStripMenuItem yesCheckNoImage = 
        new ToolStripMenuItem("Check, No Image");
    yesCheckNoImage.Checked = true;

    // Create a ToolStripMenuItem with no
    // check margin and no image margin.
    ToolStripMenuItem noCheckNoImage = 
        new ToolStripMenuItem("No Check, No Image");
    noCheckNoImage.Checked = false;

    // Add the ToolStripMenuItems to the ContextMenuStrip control.
    checkImageContextMenuStrip.Items.Add(yesCheckYesImage);
    checkImageContextMenuStrip.Items.Add(noCheckYesImage);
    checkImageContextMenuStrip.Items.Add(yesCheckNoImage);
