Parameters

• grfChange
  Type: System.UInt32
  [in] Specifies the type of change made to the file. For more information, see _VSFILECHANGEFLAGS.

• dwFileAttrs
  Type: System.UInt32
  [in] File attributes that changed.

Remarks

COM Signature

From textmgr.idl:

HRESULT IVsTextBufferDataEvents::OnFileChanged(
   [in] DWORD grfChange, 
   [in] DWORD dwFileAttrs
);

The non-TextEditorView, such as a Form view, should connect to this event to manage whether "[ReadOnly]" should be included in the document window caption. You can access this caption be calling GetProperty and specifying a value of VSFPROPID_EditorCaption for the propid parameter.

注意

The parameter dwFileAttrs is only valid if the element VSFILECHG_Attr is set in a call to FilesChanged, in which case it returns the result of the GetFileAttributes function.
