我剛剛將一個項目從Delphi 2006升級到Delphi XE。一切都按預期工作,除非我關閉我的應用程序時發生異常。從Delphi 2006升級到Delphi XE後關閉應用程序時出現無效的指針異常
它不會破壞代碼行。它在LEAVE命令中切換到CPU窗口。 如果有任何幫助,我附上了Eureka日誌。

好吧,我試過程序部分的旋轉直到錯誤走了,找到了肇事者。
這是我的webservice WSDL生成的代理。如果我在不調用服務上的任何函數的情況下創建代理對象,則會引發錯誤。
我創建了一個測試項目,但不包含代理對象創建以外的任何其他代碼,它也會引發錯誤。我也試過用另一個web服務,同樣的錯誤。這兩個Web服務都是使用Delphi 2006(.net 1.1)創建的。
最後,我嘗試使用在VS2010中創建的.net 4.0 webservice。沒問題。所以無論是德爾福XE是項目不兼容.NET 1.1 Web服務或Delphi 2006 Web服務。無論哪種方式,這是一個混亂。
任何關於如何解決這個問題,或許是一種解決方法?
這是沒有足夠的信息讓我們知道是什麼問題,請提供調用堆棧(第二個標籤在異常對話框中) – ComputerSaysNo 2010-12-14 16:41:47
使用接口? IInterface/IUnknown的? – 2010-12-14 19:00:33
