我是Windows编程的新手，我创建了一个在64位机器上运行的应用程序。该应用程序也有一个水晶报告。该应用程序完全适用于我的机器，但是当我尝试将其安装在其他机器上时，它会抛出以下错误。我已在目标PC上安装了Crystal报表运行时13，以使其正常工作，但没有任何成功。 以下是我在打开页面时遇到的错误。

************** 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.
这种例外的原因是什么？
答案 0 :(得分：1)
这与Crystal Reports无关。问题出在FillList中的MovedItems方法中。该错误意味着您在设置DataSource属性后无法将项插入ComboBox。尝试将项目添加到数据源。
