Hello,
I am currently having trouble adding items to the Outlook 2003 Context menu with Add-in Express and I was hoping someone could help me.
I have seen the examples of how to add a button directly to the context menu and that works perfectly when using the same code in the sample. What I would like to do, however, is add a Menu to the context menu and in that new menu, add 3 buttons. I was able to implement this and everything shows up correctly, however, right clicking, on an email 2 or 3 times causes Outlook to freeze until I kill the process. If I only add the menu (no buttons on the new menu), outlook doesn't freeze.
If anyone could give me a hand I would greatly appreciate it!
Here is the code I am currently using, it is broken up into a few methods and most of the code was taken from the samples. HandleContextMenu is called from the adxOutlookEvents_CommandBarsUpdate event:
==============================================================
public override void HandleContextMenu(object sender, object commandBar, object target)
{
Selection sel = null;
NameSpace nameSpace = null;
Explorer activeExplorer = null;
MAPIFolder currentFolder = null;
try
{
nameSpace = _outlookApp.GetNamespace("MAPI");
activeExplorer = _outlookApp.ActiveExplorer();
try
{
currentFolder = activeExplorer.CurrentFolder;
try
{
sel = activeExplorer.Selection;
}
catch { }
Office.CommandBar contextBar = null;
if (!AreAllSelectedItemsMail(sel))
return;
_module.CommandBarsObj = activeExplorer.CommandBars;
try
{
contextBar = _module.FindCommandBarObj("Context Menu") as Office.CommandBar;
if (contextBar == null || contextBar.Controls.Count < 1)
return;
try
{
try
{
const string irMenuTag = "My Menu";
const string caption = "New Menu";
AddContextMenu(contextBar, caption, irMenuTag);
}
catch (Exception err)
{
MessageBox.Show(err.Message, err.Source);
}
}
catch
{
}
}
finally
{
if (contextBar != null)
Marshal.ReleaseComObject(contextBar);
}
_module.CommandBarsObj = null;
}
finally
{
if (sel != null)
Marshal.ReleaseComObject(sel);
if (currentFolder != null)
Marshal.ReleaseComObject(currentFolder);
}
}
finally
{
if (nameSpace != null)
Marshal.ReleaseComObject(nameSpace);
if (activeExplorer != null)
Marshal.ReleaseComObject(activeExplorer);
}
}
private void AddContextMenu(Office.CommandBar contextBar, string caption, string controlTag)
{
// Try to find the New Menu on the context menu
Office.CommandBarControl irMenu =
contextBar.FindControl(Office.MsoControlType.msoControlPopup, Type.Missing, controlTag, Type.Missing, Type.Missing);
ADXCommandBarPopup barPopup;
if (irMenu == null)
{
contextBar.Protection = Office.MsoBarProtection.msoBarNoProtection;
if (_adxCommandBar == null)
{
_adxCommandBar = new ADXCommandBar();
_adxCommandBar.CommandBarObj = contextBar;
}
else
{
barPopup = _adxCommandBar.Controls.GetControlByControlTag(controlTag, false) as ADXCommandBarPopup;
if (barPopup != null)
{
barPopup.ControlObj = null;
_adxCommandBar.Controls.RemoveAt(_adxCommandBar.Controls.IndexOf(barPopup));
}
}
barPopup = new ADXCommandBarPopup();
barPopup.ControlTag = controlTag;
barPopup.Caption = caption;
if (_adxCommandBar.Controls.Add(barPopup) != null)
{
barPopup.ControlObj = contextBar.Controls.Add(Office.MsoControlType.msoControlPopup,
Type.Missing, Type.Missing,
(barPopup.Before > 0
? barPopup.Before
: Type.Missing), true);
barPopup.Temporary = true;
AddControl(barPopup, "Button 1", "Button Context Button", _clickHandler.DoClick, ImageIcons.Button1);
AddControl(barPopup, "Button 2", "Button 2 Context Button", _clickHandler.DoClick,
ImageIcons.Button2);
AddControl(barPopup, "Button 3", "Button 3 Context Button", _clickHandler.DoClick,
ImageIcons.Button3);
barPopup.UpdateControlObj(_module);
}
}
else
{
Marshal.ReleaseComObject(irMenu);
}
}
private ADXCommandBarControl AddControl(ADXCommandBarPopup popup, string caption, string controlTag, ADXClick_EventHandler clickHandler, ImageIcons imageIcon)
{
ADXCommandBarControl control = popup.Controls.Add(typeof (ADXCommandBarButton), controlTag, 1, 1, false);
ADXCommandBarButton button = control.AsButton;
button.ControlTag = controlTag;
button.Caption = caption;
button.Click -= clickHandler;
button.Click += clickHandler;
button.ImageList = _imageList;
button.Style = ADXMsoButtonStyle.adxMsoButtonIconAndCaption;
if (imageIcon != ImageIcons.None)
{
button.ImageTransparentColor = Color.Fuchsia;
if (_imageList.Images.Count > (int)imageIcon)
button.Image = (int)imageIcon;
}
return button;
}
==============================================================
Thanks,

Hello Ryan,
Below I post the code that works fine for me. There are moments I'd like to point to:
1. In AddContextMenu and in HandleContextMenu, I introduced new variables to keep contextBar.Controls. Your code doesn't release these COM objects. The same mistake exists in the original sample for VS 2003 (http://www.add-in-express.com/files/projects_pub/olitemscontextmenu.zip) which adds a custom toolbar button or two to the Context Menu in Outlook, is this correct? Another version of this sample (VS 2005-2008) is also available as http://www.add-in-express.com/files/projects_pub/olitemscontextmenu-vs2005.zip
2. What I really do is removing custom buttons from the popup correctly. See RemoveControlFromPopup.
3. Note that the custom popup is also shown when you right-click navigation pane shortcuts in Outlook 2003. To prevent this, you need to check if the Navigation Pane Options built-in button exists in the Context Menu. Its Office ID is 7887. This also applies to Outlook 2007.

Hi Andrei,
Thank you very much for your help with this, it worked perfectly! I guess properly removing the buttons along with the COM object references was the key. I also didn't realize about the Navigation pane options, good to know.
Again, thanks!
