Remarks

COM Signature

From vsshell.idl:

HRESULT IVsLibraryMgr::ToggleCheckAt(
   [in] ULONG nLibIndex
);

IVsLibraryMgr.ToggleCheckAt and GetCheckAt are used only if the IVsLibrary in question is not expandable (_LIB_FLAGS LF_EXPANDABLE is not set and GetLibList is not implemented), yet provides a global component for browsing. In such a case, the user sees a check box with the library's display name in the Selected Libraries dialog of the Object Browser. ToggleCheckAt is called as the user selects or un-selects this check box.

Hinweis

The Object Manager persists this checked state across Visual Studio.NET sessions.
