deskband toolbar button is not showing when IE protected mode is enabled

I have developed an add-on button that sends a tcp message to another process with the URL of the current tab. That's all it does

Since my experience is limited to managed code, I have used this article Extending Explorer with Band Objects using .NET and Windows Forms

to create my toolbar button. Problem is that it's completely not showing when IE protected mode is enabled on Windows vista and 7.

I read this article http://msdn.microsoft.com/en-us/library/bb250462(VS.85).aspx#wpm_elebp

and created an e开发者_运维百科levation policy with the GUID of my deskband , but still no use

Is there any way to handle this situation from a managed code perspective?

Try to install the add-on as an Administrator. Also, see FAQ section at http://msdn.microsoft.com/en-us/library/bb250462(VS.85).aspx#faq about APIs that will lead to Access Denied.
