Remarks

COM Signature

From ivsqueryeditquerysave2.idl

HRESULT DeclareUnreloadableFile(

   [in] const VSQEQS_FILE_ATTRIBUTE_DATA* pFileInfo
);

Use of this method is not recommended. Editors should support reload.

This method is called to ensure that the QueryEditFiles, QuerySaveFile, and QuerySaveFiles methods know that a file is not reloadable. It must be called in the following circumstances:

So the project, solution, or editor can ensure that the service knows the file is not reloadable,

-or-
When IsDocDataReloadable specifies that the file is not reloadable by returning false.

If the unreloadable file is being edited, you cannot get the latest version of it. It is possible for files to transition from being reloadable to unreloadable during the lifetime of an editor.
