Parameters
dwLink
[in]
Container-defined unique 32-bit identifier for a single link. See IOleUILinkContainer::GetNextLink.
lplpszDisplayName
[out]
Indirect pointer to the allocated full-link source display name string. The
Links dialog box will free this string.
lplenFileName
[out] Pointer
to the length of the leading file name portion of the lplpszDisplayName
string. If the link source is not stored in a file, then *lplenFileName
should be 0. For OLE links, call IOleLink::GetSourceDisplayName.
lplpszFullLinkType
[out]
Indirect pointer to the allocated full-link type string that is displayed at
the bottom of the Links dialog box. The Links dialog box will free this string.
For OLE links, this should be the full User Type name. Use IOleObject::GetUserType, specifying
USERCLASSTYPE_FULL for dwFormOfType.
lplpszShortLinkType
[out]
Indirect pointer to the allocated short-link type string that is displayed in
the listbox of the Links dialog box. The Links dialog box will free this
string. For OLE links, this should be the short User Type name. Use IOleObject::GetUserType,
specifying USERCLASSTYPE_SHORT for dwFormOfType.
lpfSourceAvailable
[out] Pointer
that returns FALSE if it is known that a link is unavailable since the link is
to some known but unavailable document. Certain options, such as Update Now,
are disabled (grayed in the UI) for such cases.
lpfIsSelected
[out] Pointer
to a BOOL variable that tells the Edit Links dialog box that this link s entry
should be selected in the dialog s multi-selection listbox. OleUIEditLinks calls this method at least
once for each item to be placed in the links list. If none of them return TRUE,
then none of them will be selected when the dialog box is first displayed. If
all of them return TRUE, then all will be displayed. That is, it returns TRUE
if this link is currently part of the selection in the underlying document,
FALSE if not. Any links that are selected in the underlying document are
selected in the dialog box; this way, the user can select a set of links and
use the dialog box to update them or change their source(s) simultaneously.
Return Values
This
method supports the standard return values E_FAIL,
E_INVALIDARG,
and E_OUTOFMEMORY, as well as the following:
S_OK
Successfully
returned link information.
E_ACCESSDENIED
Insufficient
access permissions.
Remarks
Notes To Callers
Call this
method during dialog box initialization, after returning from the Change Source
dialog box.
