IOleLink::SetSourceDisplayName

Specifies the new link source of a linked object using a display name.

HRESULT SetSourceDisplayName(

LPCOLESTR pszStatusText	//Display name of new link source
);

Parameter
pszStatusText

[in] The display name of the new link source. It may not be NULL.

Return Values
S_OK

The display name was set successfully.

MkParseDisplayName errors
Setting the display name requires calling this function; therefore, this method may return errors generated by this function.

Comments
Notes to Callers
Your container application can call IOleLink::SetSourceDisplayName when the end user changes the source of a link or breaks a link. Note that this requires the linked object to create a moniker out of the display name. If you'd rather parse the display name into a moniker yourself, your container can call IOleLink::SetSourceMoniker instead of IOleLink::SetSourceDisplayName.

If you use the OleUIEditLinks API function to display the Links dialog box, you must implement the IOleUILinkContainer interface. The dialog box calls your implementations of IOleUILinkContainer::SetLinkSource and IOleUILinkContainer::CancelLink. Your implementation of these methods can call IOleLink::SetSourceDisplayName.

If your container application is immediately going to bind to a newly specified link source, you should call MkParseDisplayName and IOleLink::SetSourceMoniker instead, and then call IOleLink::BindToSource using the bind context from the parsing operation. By reusing the bind context, you can avoid redundant loading of objects that might otherwise occur.

Notes on Provided Implementation
The contract for IOleLink::SetSourceDisplayName does not specify when the linked object will parse the display name into a moniker. The parsing can occur before IOleLink::SetSourceDisplayName returns, or the linked object can store the display name and parse it only when it needs to bind to the link source. Note that parsing the display name is potentially an expensive operation because it might require binding to the link source. The provided implementation of IOleLink::SetSourceDisplayName parses the display name and then releases the bind context used in the parse operation. This can result in running and then stopping the link source server.

If the linked object is bound to the current link source, the implementation of IOleLink::SetSourceDisplayName breaks the connection.

For more information on how the linked object stores and uses the moniker to the link source, see IOleLink::SetSourceMoniker.

    Nostalgia .Net     .Net is powerful, but not all-powerful, so sometimes we need to use Win32 API for our .Net applications. It's simple enough with Platform Invoke if you have Win32 skill, but we do not always have time to dig the ancient documentation, declare the special types that are compatible with Win32, find the values of the Win32's constants and so on. Nostalgia .Net offers several simple-to-use classes, and components that will allow you to forget about the headache of Win32 and just use the power of Win32 in your application the same way as you use the native.
