abstract member GetProjrefOfItem : Microsoft.VisualStudio.Shell.Interop.IVsHierarchy * uint32 * string -> int

Public Function GetProjrefOfItem (pHierarchy As IVsHierarchy, itemid As UInteger, ByRef pbstrProjref As String) As Integer

Parameters

pHierarchy: IVsHierarchy

[in] Pointer to the IVsHierarchy interface.

itemid: UInt32

[in] Valid item identifier within the project; not a VSITEMID value.

pbstrProjref: String

[out] Pointer to the project reference string.

Returns

Int32

If the method succeeds, it returns S_OK. If it fails, it returns an error code.

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.
