Question

我正在尝试追踪此错误，甚至陷阱以防止它崩溃应用程序。该应用程序使用.NET 4在VB.NET中编写。

Application: Satcom Discovery Socket.exe
Framework Version: v4.0.30319
Description: The process was terminated due to an unhandled exception.
Exception Info: System.AccessViolationException

事件日志中的另一个错误是

错误应用程序名称：Satcom Discovery Socket.exe，版本：1.0.0.0，时间戳：0x5465cfdd 错误模块名称：ntdll.dll，版本：6.1.7601.18247，时间戳：0x521ea8e7 异常代码：0xc0000005 故障偏移：0x0002e3be 错误进程id：0x94c 错误应用程序启动时间：0x01d004411406ec37 错误的应用程序路径：D：\ SocketDaemon \ Satcom Discovery Socket.exe 错误模块路径：C：\ Windows \ SysWOW64 \ ntdll.dll 报告编号：2cefa3fd-70d4-11e4-8cc0-002219a5cbd1

有什么想法吗？

我以为我有未处理的异常被以下代码

所困

            'for regular unhandled stuff 
        AddHandler AppDomain.CurrentDomain.UnhandledException, AddressOf MYGeneralExceptionHandler
        'for threads behind forms 
        AddHandler Application.ThreadException, AddressOf MyThreadExceptionHandler

任何指针都会非常感激。

谢谢，
