为什么会出现这种错误？？？

[dreamup]

编绎能够正常通过，但却无法创建.exe文件。。。。。

提示说：

这段程序可以运行！！！！！！
你应该新建一个空的“Win32 Application”,然后新建一个空的C++ Source File加到项目中，然后把这段代码拷贝到文件中即可编译运行，没问题的。

恩，的确
工程中多了个模块

LINK : fatal error LNK1168: cannot open Debug/keyboard.exe for writing
如果我没猜错的话,你的程序名就叫keyboard.
这说明你的keyboard.exe正在运行,指上一次运行的那个.
所以它不可写入.只要把它关掉,再链接就不会有问题了!

打开进程管理器,把keyboard结束掉
