Parameters

  • itemidCaller
    Type: System.UInt32

    [in] Hierarchy item identifier of the document in the project. Used with IDO_ActivateIfOpen. For more information, see VSITEMID.

  • pszMkDocument
    Type: System.String

    [in] String form of the unique moniker identifier of the document in the project system, for example, the full path to the file. In non-file cases, this identifier is often in the form of a URL.

  • rguidLogicalView
    Type: System.Guid%

    [in] GUID identifying the logical view. For a list of logical view GUIDS, see Logical View and Physical View.

  • grfIDO
    Type: System.UInt32

    [in] Flags that control what actions are performed on an open document. For more information, see __VSIDOFLAGS.

  • pitemidOpen
    Type: array<System.UInt32[]

    [out] Pointer to the hierarchy item identifier of the open document in the project system. For more information see VSITEMID.

  • pfOpen
    Type: System.Int32%

    [out, retval] true if the document is currently open; false if the document is not open.

Return Value

Type: System.Int32
If the method succeeds, it returns S_OK. If it fails, it returns an error code.
