Article
02/22/2024

Forces selected links to connect to their source and retrieve current information.

Syntax

HRESULT UpdateLink(
  [in] DWORD dwLink,
  [in] BOOL  fErrorMessage,
  [in] BOOL  fReserved
);

Parameters

[in] dwLink

Container-defined unique identifier for a single link. Containers can use the pointer to the link's container site for this value.

[in] fErrorMessage

Determines whether the caller (implementer of IOleUILinkContainer) should show an error message upon failure to update a link. The Update Links dialog box sets this to FALSE. The Object Properties and Links dialog boxes set it to TRUE.

[in] fReserved

This parameter is reserved and must be set to FALSE.

Return value

This method returns S_OK on success. Other possible return values include the following.

Return code	Description
E_ACCESSDENIED	Insufficient access permissions.
E_FAIL	The operation failed.
E_INVALIDARG	The specified identifier is invalid.
E_OUTOFMEMORY	There is insufficient memory available for this operation.

Remarks

Notes to Callers

Call this method with fErrorMessage set to TRUE in cases where the user expressly presses a button to have a link updated, that is, presses the links' Update Now button. Call it with FALSE in cases where the container should never display an error message, that is, where a large set of operations are being performed and the error should be propagated back to the user later, as might occur with the Update links progress meter. Rather than providing one message for each failure, assuming there are failures, provide a single message for all failures at the end of the operation.

Notes to Implementers

For OLE links, call IOleObject::Update.
