Remarks
COM Signature
From vsshell.idl:
HRESULT IVsSolution::GetProjrefOfItem(
[in] IVsHierarchy *pHierarchy,
[in] VSITEMID itemid,
[out] BSTR *pbstrProjref
);
The following is a description of how the GetProjrefOfItem method is used to support drag-and-drop operations:
The CF_VSPROJECTITEMS and CF_VSPROJECTS clipboard formats use the DROPFILES structure in the same manner as CF_HDROP or CF_PRINTERS. The data that follows the DROPFILES structure is a double-NULL-terminated list of Projref strings. The consumer of the drop operation can use the Windows API DragQueryFile to examine the data in the DROPFILES structure. CF_VSPROJECTS format is offered when the Projref strings identify projects as a whole, that is, *pitemid == VSITEMID_ROOT. The CF_VSPROJECTITEMS format is offered when the Projref strings identify one or more individual project items. Either CF_VSPROJECTS or CF_VSPROJECTITEMS should be offered, but never both.
