CommandBars.FindControl throws an exception
I am trying to use the FindControl method of the CommandBars object in the VSTO Word add-on to get what else is a command line object The code looks like this
private void WireContextMenu(string MenuID,string Tag, string ID, ref Office.CommandBarButton Control)
{
try
{
object missing = System.Type.Missing;
Control = (Office.CommandBarButton)this.Application.CommandBars[MenuID].FindControl((object)Office.MsoControlType.msoControlButton, ID, Tag, missing, missing);
if (Control == null)
{
Control = (Office.CommandBarButton)this.Application.CommandBars[MenuID].Controls.Add(Office.MsoControlType.msoControlButton, ID, missing, missing, missing);
Control.Caption = "Biolit Markup Selection";
Control.Tag = Tag;
}
Control.Click += new Microsoft.Office.Core._CommandBarButtonEvents_ClickEventHandler(this.cb_Click);
}
catch (Exception Ex)
{
}
}
The FindControl method throws a type mismatch exception (-2147352571) Any ideas this is the right way to add an item to the word context menu, then make sure you haven't added it if it already exists Thanks

you are using Missing where Missing is not allowed as a ref parameter: link text http://msdn.microsoft.com/en-us/library/system.type.missing.aspx
use code like this:
object type = MsoControlType.msoControlPopup;
object id = 1;
object tag = null;
object visible = 1;
object recusive = false;
//object missing = System.Type.Missing;
CommandBarControl barControl = popParent.FindControl(type, id, tag, visible, recusive);
