This example adds an icon to a command bar button on a custom menu in Microsoft Office Outlook 2003. The icon is included in the project resources. For more information about project resources, see Adding and Editing Resources (Visual C#) and How to: Add or Remove Resources.

To add custom icons

  1. Add code to the Outlook project's ThisApplication.vb or ThisApplication.cs file to create CommandBarPopup and CommandBarButton controls that represent the custom menu and menu command. This code checks to see whether the menu exists. If it does exist, this code removes the menu. It then adds the new menu.

    Visual Basic 
    Private MenuBar As Office.CommandBar
Private newMenuBar As Office.CommandBarPopup
Private ButtonOne As Office.CommandBarButton
Private menuTag As String = "AUniqueName"


Private Sub ThisApplication_Startup(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Startup
    RemoveMenubar()
    AddMenuBar()
End Sub

Private Sub AddMenuBar()
    Try
        menuBar = Me.ActiveExplorer().CommandBars.ActiveMenuBar
        newMenuBar = menuBar.Controls.Add( _
            Office.MsoControlType.msoControlPopup, _
            Temporary:=False)
        If newMenuBar IsNot Nothing Then
            newMenuBar.Caption = "See New Icon"
            newMenuBar.Tag = menuTag
            buttonOne = newMenuBar.Controls.Add( _
                Office.MsoControlType.msoControlButton, _
                Before:=1, Temporary:=False)
            With buttonOne
                .Style = Office.MsoButtonStyle _
                .msoButtonIconAndCaption
                .Caption = "New Icon"
                .FaceId = 65
                .Tag = "c123"
                .Picture = getImage()
            End With
            newMenuBar.Visible = True
        End If
    Catch Ex As Exception
        MessageBox.Show(Ex.Message)
    End Try
End Sub

Private Sub RemoveMenubar()
    Try
        ' If the menu already exists, remove it.
        Dim foundMenu As Office.CommandBarPopup = _
            Me.ActiveExplorer().CommandBars.ActiveMenuBar. _
            FindControl(Office.MsoControlType.msoControlPopup, _
            System.Type.Missing, menuTag, True, True)
        If foundMenu IsNot Nothing Then
            foundMenu.Delete(True)
        End If
    Catch Ex As Exception
        MessageBox.Show(Ex.Message)
    End Try
End Sub
    C# 
    private Office.CommandBar menuBar;
private Office.CommandBarPopup newMenuBar;
private Office.CommandBarButton buttonOne;
private string menuTag = "AUniqueTag";

private void ThisApplication_Startup(object sender, System.EventArgs e)
{
    RemoveMenubar();
    AddMenuBar();
}

private void AddMenuBar()
{
    try
    {
        menuBar = this.ActiveExplorer().CommandBars.ActiveMenuBar;
        newMenuBar = (Office.CommandBarPopup)menuBar.Controls.Add(
            Office.MsoControlType.msoControlPopup, missing,
            missing, missing, false);
        if (newMenuBar != null)
        {
            newMenuBar.Caption = "See New Icon";
            newMenuBar.Tag = menuTag;
            buttonOne = (Office.CommandBarButton)
                newMenuBar.Controls.
            Add(Office.MsoControlType.msoControlButton, System.
                Type.Missing, System.Type.Missing, 1, true);
            buttonOne.Style = Office.MsoButtonStyle.
                msoButtonIconAndCaption;
            buttonOne.Caption = "New Icon";
            buttonOne.FaceId = 65;
            buttonOne.Tag = "c123";
            buttonOne.Picture = getImage();
            newMenuBar.Visible = true;
        }
    }
    catch (Exception ex)
    {
        MessageBox.Show(ex.Message);
    }
}

private void RemoveMenubar()
{
    // If the menu already exists, remove it.
    try
    {
        Office.CommandBarPopup foundMenu = (Office.CommandBarPopup)
            this.ActiveExplorer().CommandBars.ActiveMenuBar.
            FindControl(Office.MsoControlType.msoControlPopup,
            System.Type.Missing, menuTag, true, true);
        if (foundMenu != null)
        {
            foundMenu.Delete(true);
        }
    }
    catch (Exception ex)
    {
        MessageBox.Show(ex.Message);
    }
}

  2. Create a new class named ConvertImage. This class uses System.Forms.Axhost to convert an Image file to an image type that can be applied to the menu item.

    Visual Basic 
    Public Class ConvertImage
    Inherits System.Windows.Forms.AxHost
    Public Sub New()
        MyBase.New("59EE46BA-677D-4d20-BF10-8D8067CB8B32")
    End Sub

    Public Shared Function Convert(ByVal Image _
        As System.Drawing.Image) As stdole.IPictureDisp
        Convert = GetIPictureFromPicture(Image)
    End Function
End Class
    C# 
    sealed public class ConvertImage : System.Windows.Forms.AxHost
{
    private ConvertImage()
        : base(null)
    {
    }
    public static stdole.IPictureDisp Convert
        (System.Drawing.Image image)
    {
        return (stdole.IPictureDisp)System.
            Windows.Forms.AxHost
            .GetIPictureDispFromPicture(image);
    }
}

  3. Add a method to convert the icon file into an Image file by adding it to an ImageList. This code sends the Image file to the ConvertImage.Convert method you created and then returns the file to the caller.

    Visual Basic 
    Private Function getImage() As stdole.IPictureDisp
    Dim tempImage As stdole.IPictureDisp = Nothing
    Try
        Dim newIcon As Icon = My.Resources.Icon1
        Dim newImageList As New ImageList
        newImageList.Images.Add(newIcon)
        tempImage = ConvertImage.Convert(newImageList.Images(0))
    Catch ex As Exception
        MessageBox.Show(ex.Message)
    End Try
    Return tempImage
End Function
    C# 
    private stdole.IPictureDisp getImage()
{
    stdole.IPictureDisp tempImage = null;
    try
    {
        System.Drawing.Icon newIcon = 
            Properties.Resources.Icon1;

        ImageList newImageList = new ImageList();
        newImageList.Images.Add(newIcon);
        tempImage = ConvertImage.Convert(newImageList.Images[0]);
    }
    catch (Exception ex)
    {
        MessageBox.Show(ex.Message);
    }
    return tempImage;
}

Compiling the Code

This example requires:

  • An icon named Icon1 in the project resources.

Adding a Mask      Ragna ... Dwz2006   |   Edit   |   Show History

If you want to also have a mask created the following code change creates a quick mask

        private void SetImage(CommandBarButton button, Icon newIcon)
        {
            try
            {
                ImageList newImageList = new ImageList();
                newImageList.ColorDepth = ColorDepth.Depth8Bit;
                newImageList.ImageSize = new Size(16, 16);
                newImageList.Images.Add(newIcon);

                button.Picture = ConvertImage.Convert(newImageList.Images[0]);

                Bitmap mask = (Bitmap)newImageList.Images[0].Clone();
                for (int x = 0; x < 16; x++)
                {
                    for (int y = 0; y < 16; y++)
                    {
                        mask.SetPixel(x,y, (mask.GetPixel(x, y) == Color.Transparent || mask.GetPixel(x,y).Name == "0") ? 
                                            Color.White : Color.Black);
                    }
                }
                button.Mask = ConvertImage.Convert(mask);
            }
            catch (Exception ex)
            {
                MessageBox.Show(ex.Message);
            }
        }

Adding a Mask in VB.NET, accounting for semi-transparent pixels      iosys   |   Edit   |   Show History
Thanks to the previous comment I was able to understand how to use an image mask. I adapted the code to VB.NET and modified it to create a gray scale mask instead of just a black and white mask.

Public Class IPictureDisp
    Inherits System.Windows.Forms.AxHost
    Public Sub New()
        MyBase.New("59EE46BA-677D-4d20-BF10-8D8067CB8B32")
    End Sub

    Public Shared Function FromImage(ByVal pImg As System.Drawing.Image) As stdole.IPictureDisp
        Dim b As New Bitmap(16, 16)
        Dim g As Graphics = Graphics.FromImage(b)
        ' fill the bitmap with white
        g.FillRectangle(Brushes.White, 0, 0, 16, 16)
        ' draw the image over the white bitmap
        g.DrawImage(pImg, 0, 0, 16, 16)
        ' return the opaque image
        Return GetIPictureFromPicture(b)
    End Function

    Public Shared Function MaskFromImage(ByVal pImg As System.Drawing.Image) As stdole.IPictureDisp
        Dim b As New Bitmap(16, 16)
        Dim g As Graphics = Graphics.FromImage(b)
        ' draw the image over the transparent bitmap
        g.DrawImage(pImg, 0, 0, 16, 16)
        ' convert pixels to grayscale
        For x As Integer = 0 To 15
            For y As Integer = 0 To 15
                ' get the pixel alpha
                Dim pa As Integer
                pa = b.GetPixel(x, y).A
                ' get the grayscale alpha equivalent of the pixel alpha
                Dim pg As Integer
                pg = 255 - pa
                ' replace the current pixel with a grayscale equivalent
                b.SetPixel(x, y, Color.FromArgb(pg, pg, pg))
            Next
        Next
        ' return the picture
        Return GetIPictureFromPicture(b)
    End Function
End Class

To use the code, just do something like:

button.Picture = IPictureDisp.FromImage(my.resources.icon1)
button.Mask = IPictureDisp.MaskFromImage(my.resources.icon1)
