SHLoadNonloadedIconOverlayIdentifiers function (shellapi.h)

  • Άρθρο

Signals the Shell that during the next operation requiring overlay information, it should load icon overlay identifiers that either failed creation or were not present for creation at startup. Identifiers that have already been loaded are not affected.

Syntax

SHSTDAPI SHLoadNonloadedIconOverlayIdentifiers();

Return value

Type: HRESULT

Always returns S_OK.

Remarks

A call to SHLoadNonloadedIconOverlayIdentifiers does not result in the immediate loading of a Shell extension, nor does it cause an icon overlay handler to be loaded. A call to SHLoadNonloadedIconOverlayIdentifiers results in a situation such that the next code to ask for icon overlay information triggers a comparison of icon overlays in the registry to those that are already loaded. If an icon overlay is newly registered and the system has not already reached its upper limit of fifteen icon overlays, the new overlay is loaded. SHLoadNonloadedIconOverlayIdentifiers alone does not load a new icon overlay; you also need to trigger an action that uses the overlay, such as a refresh of a Windows Explorer view.
