Question

我已经使用Visual Studio 2008编译和.exe。在任何其他PC上的w7上，它的工作正常。但是在带有XP的PC上，它给了我一些我不明白的错误：

    See the end of this message for details on invoking 
just-in-time (JIT) debugging instead of this dialog box.

************** 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>

我是.net的新用户，所以请清楚说明我该怎么做谢谢。

您是否尝试实例化未在XP计算机上安装的字体？也许是默认情况下安装Windows 7而不是XP？
