我正在开发 VC++ 应用程序，其中所有汇款交易都显示在动态网格控件之一中。用户必须双击该主网格控件，然后弹出详细信息窗口。在该详细级别中，会显示该主条目的交易记录。（这就像向下钻取细节级别）。现在在这个细节窗口网格控件中，第一次只显示 1000 条记录。要在动态网格 ctrl 中显示下一个 10000 条记录，用户单击“获取下一个”按钮。这是应用程序出错的要点：
“Qpay.exe 中 0x78594826 处未处理的异常：0x800000x26：已执行长跳转。” 和应用程序被关闭。
应用程序使用 Oracel11g 数据库。
有时它的错误消息就像“未处理的异常错误...”，下面的错误代码显示：

************** JIT Debugging **************
To enable just-in-time (JIT) debugging, the .config file for this
application or computer (machine.config) must have the
jitDebugging value set in the system.windows.forms section.
The application must also be compiled with debugging
enabled.
For example:
<configuration>
<system.windows.forms jitDebugging="true" />
</configuration>
When JIT debugging is enabled, any unhandled exception
will be sent to the JIT debugger registered on the computer
rather than be handled by this dialog box.
