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

我在.net中新，所以请解释清楚，我应该怎么办谢谢。

Answer 1

你是否试图实例化未安装在XP机器上的字体？也许是默认安装了Windows 7而不是XP的一款软件？
