使用Tessnet2的.NET應用程序失敗

Question

我有一個使用Tessnet2的應用程序。當我嘗試調用其Init方法時，該應用程序失敗。
失敗只是可怕 - 沒有例外（任何），沒有任何錯誤的痕跡，甚至沒有「發送報告」窗口。該應用程序的流程只是被拒絕。

有問題的代碼是：

Recogniser = new Tesseract(); 
Recogniser.SetVariable("tessedit_char_whitelist", Whitelist); 
Recogniser.SetVariable("unlv_tilde_crunching", false); 
Recogniser.Init(null, "eng", false); // FAILURE IS HERE 

夫婦的音符可能會有所幫助：

• Tessnet2需要的Visual C++ 2008運行時。不知道它應該是msvcm90.dll，msvcm80.dll。
• 該應用程序是桌面WPF。它工作過（我認爲我添加了Web引用來消費SOAP Web服務，但我試圖刪除它沒有結果）。
• 單元測試與完美配合無故障。

從這些意見聽起來像WPF應用程序本身的問題。

只有一條信息，我已經是調試過程中的輸出：

而且最後一塊時，應用程序失敗：

更新：我已經檢查了事件日誌。 「SideBySide」來源沒有任何條目。只有與該問題有關的條目如下，但不幸的是它並沒有告訴我很多：

在此先感謝您的任何提示。

Answer 1

我想出了問題所在。

簡短回答： 使用SaveFileDialog後，該應用的工作目錄被更改。這導致Tesseract無法找到相關文件。

夫婦的我做了那件事：

1. 創建了一個使用Tessnet2一個新的WPF應用程序。
2. 啓動它 - >它失敗的方式完全一樣。
3. 我發現我錯過了添加tesseract所需的文件。
4. 添加它們 - >該應用程序開始工作。

比移動到我的應用程序：
我經過由正方體所需的文件。所有這些都是有效的。

所以一定有別的東西涉及到不能夠訪問文件：

1. 沒有權限。
2. 位置不正確。

檢查1日 - 一切正常。
檢查第二個 - 所有文件都在正確位置相對應用程序當前目錄。

看到了點??
但事實證明，應用程序的文件應該在相同的工作目錄。

使用SaveFileDialog後工作目錄已更改！

如果我不使用應用程序的對話框工作。
我怎麼可能從所有的「錯誤信息」中得出這個結論...
希望這會幫助別人。

Answer 2

看看windows系統事件日誌（開始 - >設置 - >控制面板 - >管理 - >事件查看器）。可能您會從Windows SideBySide經理那裏找到條目。

輸出的最後一行顯示SideBySide中的dll已被加載。

我最近有類似的問題。直到我們查看事件日誌，才提示故障原因。
