Can I Programatically Modify the IDE's Context Menu's?

Question

I am trying to create an additional menu item for the "Project and Solutions Context Menus>Solution" menu. However, I wanted this context menu to appear ONLY when a certain solution was opened, otherwise I don't want it to show. I figured I could use the MACROS within the Visual Studio IDE. There are events that run on the opening of solutions & projects, etc.

My question is, can I create the Context Menu I want programatically, point it to the MACRO I want it to run, and then programatically attach it to the CONTEXT menu inside the IDE that I want to display it in?

I found the answer to my question. I used the following code to create the menu items I needed:

Private WithEvents _objSolutionExplorer_ContextMenu_ItemHandler As EnvDTE.CommandBarEvents
Private _objHash_ContextMenuItemHandlers As New Hashtable

Private Function CreateContextMenuButtonItem(ByVal p_objMenuItem As Object, ByVal p_strMenuItemCaption As String) As CommandBarButton

            p_objMenuItem.Controls.Item(intCounter).Delete()
            Exit For
        End If
    Next
    If EnvironmentEvents._objHash_ContextMenuItemHandlers.Contains(p_strMenuItemCaption) Then
        EnvironmentEvents._objHash_ContextMenuItemHandlers.Remove(p_strMenuItemCaption)
    End If
