What Are DeskBands?
There are 4 types of deskbands. A Communications Band
which sits at the
bottom of an instance of IE4+. An Information Band
sits on the left hand
side of an instance of IE4+, like the search bar that allows you to search for
files or folders on a hard drive. A Desk Band
sits on the desktop, it can
float or dock to any of the 4 sides of your monitor. The final type is a Toolbar
which sits in the rebar space of Internet Explorer, like the address bar.
To see this, start
IE4+. Click the "View" menu item, go down to the "Explorer Bar" menu item. The
top half above the seperator are the available Information Bands, the bottom
half are the communication bands.
To see a deskband, right click on the
taskbar (area connected to the start button). Select the toolbar's menu item
from the context menu. listed are the available deskbands.
Deskbands can also reside as toolbars inside IE4+. The wizard does not currently provide this
code although I do have it available. I will be updating the wizard in the next
week or so to support toolbars and be more configurable.
In this version you no longer need the Microsoft Installer installed to be able to use this ATL Object
Wizard. In the past the files were stored in an MSI file which would install the files to the correct
location and allow for easy uninstalltion. To allow more people to use the Wizard. I have moved the files
out of the MSI and leave it to the user to place them in the correct location using the instructions below.
- Extract the files from the source zip above to your Visual Studio location under the following relative path
- Run the RegSvr32.exe from a command prompt on RBDeskband.dll.
Path Examples For Step 1:
C:\Program Files\Microsoft Visual Studio\Common\MSDev98\Template\ATL
To create a DeskBand base implementation, do the following:
- Start the ATL Object Wizard using the 'New ATL Object' option avalable from the Insert menu.
- Select the "DeskBand" ATL Object Wizard component from the "RadBytes" category.
- Fill in the Names Dialog page with your Deskband information.
- Select the "DeskBand ATL Object Wizard" Tab.
- Select at least one DeskBand type you want to expose your band as.
- Click Ok
- Your project will be updated with the associated class files needed to compile your base implemenation of a deskband.
I Ran The Wizard But Now What?
All that is required of you is to implement your content and inner workings for the band you created.
A base window exists that is a static. This is there for easy pullout and inseration of any replacement code.
I choose this instead of attaching a CWindowImpl directly to the deskband for ease of change, use, and adaptability.
My Deskband Is Not Listed In The Menu Items
Make sure that you are looking at the correct list of menu items for
the type of band you created.
Also remember that the
caches the list of Explorer Bars and Toolbars on first access of the menu for the life of your Windows session, not IE session.
So if you have accessed the menu during this session you will either need to log off and log back on or kill
Auto Generated Code
The output created is a Source, Header, and Registry Resource files from the Short Name supplied in the ATL
Object Wizard property page. The files that get modified by the wizard are: your main source, IDL, RC, and DSP
The code generated will compile both under UNICODE and ANSI.

Band Registration problem, Threading model was set to Single [Hwan, Erik Funkenbusch]
Removed MSI requirment. [Siddhartha Ghosal]
Removed the Thank you dialog. I decided it was annoying and useless.
Added new Wizard Page to allow creation of Band in multiple ways.
Added Internet Explorer toolbar support
Use ATL CATEGORY_MAP [Erik Funkenbusch]
Testing has shown that adding numerous Bands to a project using the Wizard causes VC to insert #include directives at the bottom of the project source file. No known fix and infrequent occurance.
Adding multiple Internet Explorer Toolbars to one project will cause redefinition of
HKEY hKeyLocal = NULL;. Fix is to remove redundant definition.
