[英]Can't handle exceptions when invoking C# function from unmanaged C++ code
[英]Troubleshooting: Can't find a referenced unmanaged dll when invoking custom code via a Word code-behind
內容:
我在問題行上放置了一個斷點,清除了輸出窗口,按F10鍵,在運行該行時比較了輸出(將對象添加到ObservableCollection中,該對象的CollectionChanged處理程序具有加載非托管代碼的代碼)
情況1:雙擊EXE。

The thread 'Win32 Thread' (0x12ec) has exited with code 0 (0x0).
情況2:運行同一行,但從.cs文件后面的Word代碼中啟動
A first chance exception of type 'System.IO.FileNotFoundException' occurred in WindowsBase.dll
The program '[5320] WINWORD.EXE: Managed' has exited with code 0 (0x0).
我努力了
我注意到Word似乎正在通過托管引用程序集將其復制到以下代碼段中所示的位置..這可能是調查的結果。 但是,為什么要這么做呢?為什么要解析非托管的DLL ?。我不知道。 同樣在第一個片段中,從WinSXS路徑中加載了一些DLL,這也可能是另一個線索。
'WINWORD.EXE' (Managed): Loaded 'C:\Documents and Settings\pillaigi\Local Settings\Application Data\assembly\dl3\6HQYB5GK.LY0\KC4WN109.HT4\4d81c901\70abeb86_124ec901\MyWPFPlotPopup.DLL', Symbols loaded.
終於優雅地關閉了...幫助!
要找出導致問題的dll是什么,以及在哪里尋找dll,請使用ProcessMon(不包含sysinternals)。
