  • This CodeProject comment does this by simulating keystrokes.
  • Vista + has an API for this, ShowDeskBand and HideDeskBand

  • Edit: this code can now add a desktop strip object (from Pinvoke.net and these two MSDN forum questions):

    [ComImport] [InterfaceType(ComInterfaceType.InterfaceIsIUnknown)] [Guid("4CF504B0-DE96-11D0-8B3F-00A0C911E8E5")] public interface IBandSite { [PreserveSig] uint AddBand([In, MarshalAs(UnmanagedType.IUnknown)] Object pUnkSite); [PreserveSig] void RemoveBand(uint dwBandID); } private uint AddDeskbandToTray(Guid Deskband) { Guid IUnknown = new Guid("{00000000-0000-0000-C000-000000000046}"); Guid ITrayBand = new Guid("{F60AD0A0-E5E1-45cb-B51A-E15B9F8B2934}"); Type TrayBandSiteService = Type.GetTypeFromCLSID(ITrayBand, true); IBandSite BandSite = Activator.CreateInstance(TrayBandSiteService) as IBandSite; object DeskbandObject = CoCreateInstance(Deskband, null, CLSCTX.CLSCTX_INPROC_SERVER, IUnknown); return BandSite.AddBand(DeskbandObject); }

And for example, use:

 Guid address_toolbar_guid = new Guid("{01E04581-4EEE-11D0-BFE9-00AA005B4383}"); uint band_id = AddDeskbandToTray(address_toolbar_guid);

It would be prudent that a similar call to RemoveBand would also do the trick, but so far I cannot get this code to work. Another problem: the added column closes when the added application closes.

You may want to check out this article . It looks like you can only do this (officially) in Vista using the ITrayDeskBand interface .

I can’t find the exact url right now, but I remember that it was discussed around the PDC2008, where basically it wasn’t included specifically so that random programs could not fill the task bar without user consent.

A side effect of this is that very few users even turned on the WMP panel by default.

From what I understand, the locations and values ​​of taskbars are stored in the registry (forgot the exact location), so if you find a specific registry key, you can take its location and make your installer insert the registry key on the computer to the taskbar.

Not quite the answer to your question, but please, please: do not write shell extensions (and the taskbar is a shell extension) in .NET!

That is why .

Basically, you are violating other applications.

if you check well, the google toolband exists while exe is running (GoogleDesktop.exe), so if you insist on how a web browser or search bar is created, you should check TrayBandSiteService again and make exe support ...
