In an earlier post, I explained how to host Preview Handlers in Windows Forms. You may recall that Preview Handlers are implementations of the COM interface IPreview. Handler and are initialised either by a file or a stream depending on whether they implement IInitialize. Windows Vista X86 Sp1 Activator Technique At HomeWith. Stream or IInitialize. With. File. I observed recently that the MAPI Mail Preview Handler the handler registered for Outlook. MSG files did not implement either of the aforementioned interfaces. After some further research, I have discovered that there is a third initialisation technique which some preview handler implementations support to the exclusion of all others. The COM interface IInitialize. With. Item is used to initialise a preview handler or thumbnail provider, etc with an implementation of IShell. Item. The latter interface is used by the Windows Shell API and represents a file, folder or virtual item in Windows Explorer. So why insist on a shell item instead of initialising the preview handler with a file or stream Well, you have to remember that the primary host for preview handlers is, of course, Windows Explorer which works primarily with shell items, rather than raw files or streams. They also remove the need for preview handlers to know the location of the item on disk if indeed it is even on disk, allowing a wider variety of content to be loaded into them. Declaration. The declaration for the interface is as follows internal const string GUIDISHELLITEM 4. Dont worry, ill explain that later. Interface. TypeCom. Interface. Type. Interface. Is. IUnknown. Guid7.

Recalling the implementation of Preview. Handler. Host my Windows Forms control, we can add a third condition to the section which initialises the preview handler if m. Current. Preview.

There are two versions of the interface, one for compatibility with Windows XP SP1 and the other for Vista and onwards, the parameter determines which one to create. Final words. So, what does this enable us to do Well, to date ive only come across one preview handler that insists on being initialised in this manner the MAPI Mail Preview Handler 4. Ucla Medical Programs For High School Students. However, in the business software I write, being able to preview Outlook messages is a significant requirement unto itself. Since Windows 7 ships with several more preview handlers than Vista did, it follows that the likelihood of encountering more which are initialised from shell items will increase. Download.
