Remarks

COM Signature

From textmgr.idl:

HRESULT IVsProvideColorableItems::GetItemCount(
   [out] int *piCount
);

The core editor calls GetItemCount when it is loading a language service and needs to know how many custom colorable items the language service is proffering. This count includes only the number of colors the language service actually provides. If the language service chooses to include a placeholder for index 0, that placeholder should not be included in the count returned from this method.
