IMessageFilter爲BackgroundWorker的[EXCEL]

Question

運行下面的代碼時，我目前得到以下錯誤：
錯誤：

COMException was unhandled
An unhandled exception of type 'System.Runtime.InteropServices.COMException' occurred in mscorlib.dll

Additional information: Call was rejected by callee. (Exception from HRESULT: 0x80010001 (RPC_E_CALL_REJECTED))

代碼：

Sub DisplayInfo() 
     txtSample1.Text = worksheet.Cells(((CurrentPage * 8) + 1), 3).Value 

我懷疑這是這個背景的結果w orker：

Private Sub bwSaveAndLoad_DoWork(sender As Object, e As DoWorkEventArgs) Handles bwSaveAndLoad.DoWork 
    Try 
      workbook.Save() 
    Catch 
    End Try 
End Sub 

這裏的WorkCompleted爲DoWork的：

Private Sub bwSaveAndLoad_RunWorkerCompleted(sender As Object, e As RunWorkerCompletedEventArgs) Handles bwSaveAndLoad.RunWorkerCompleted 
    Call DisplayInfo() 

與谷歌一個漫長而乏味的交談後，我被告知，我需要實現IMessageFilter錯誤處理程序。我看了一下它的文檔，但我仍然不知道該怎麼做。有人能夠指出我正確的方向嗎？

這裏是一個很好的例子。我不知道我在找CoRegisterMessageFilter。這整個過程中我只是谷歌搜索IMessageFilter，但周圍使用CoRegisterMessageFilter（）這個工作很漂亮！：
