Used in conjunction with the value shown above, the following optional value is also necessary if you want to use the Explorer Bar to display HTML. Another optional value defines the default width or height of the Explorer Bar, depending on whether it is vertical or horizontal, respectively. The BarSize value should be set to the width or height of the bar. The value requires eight bytes and is placed in the registry as a binary value.
The first four bytes specify the size in pixels, in hexadecimal format, starting from the leftmost byte. The last four bytes are reserved and should be set to zero. As an example, the full registry entries for an HTML-capable Explorer Bar with a default width of 0x pixels are shown here.
This example goes through the implementation of the sample vertical Explorer Bar shown in the introduction. The very simple implementation used in the Explorer Bar sample could actually be used for either type of Explorer Bar, or a desk band, by simply registering it for the appropriate component category.
More sophisticated implementations will need to be customized for each object type's display region and container. However, much of this customization can be accomplished by taking the sample code and extending it by applying familiar Windows programming techniques to the child window. For example, you can add controls for user interaction, or graphics for a richer display. The first three functions are standard implementations and will not be discussed here.
The Class Factory implementation is also standard. The constructor, destructor, and IUnknown implementations are straightforward, and will not be discussed here. See the sample code for details. The punkSite parameter will be set to the site's IUnknown pointer. In general, a SetSite implementation should perform the following steps:. The Explorer Bar sample implements SetSite in the following way. In this sample, window creation is also handled. If the window does not exist, this method creates the Explorer Bar's window as an appropriately sized child of the parent window obtained by SetSite.
The sample's GetSite implementation simply wraps a call to the site's QueryInterface method, using the site pointer saved by SetSite. If there is no persistent data, the methods must still return a success code. The Explorer Bar sample does not use any persistent data and has only a minimal implementation of IPersistStream. The IDeskBand interface is specific to band objects. The IDockingWindow interface has three methods.
The ShowDW method either shows or hides the Explorer Bar's window, depending on the value of its parameter. Type the paths to your custom folder locations in the Item text boxes and click OK. Keep in mind that once you enable this setting, you must manually specify all five locations.
If you want to keep some of the default locations or specify other common locations, in addition to your custom items, you must use one of the following special shortcuts:.

DockPosition - the available positions are vertical at the left of the Internet Explorer window and horizontal at the bottom. MaxSize -specifies the maximal size of the bar; the default value, which is -1, means "no restrictions".
