Error executing link.exe.
Creating browse info file...first.exe - 2 error(s), 0 warning(s)
这是怎么回事哎,谢谢各位了

Answer 1

你的工具类型是控制台的,改为win32

Answer 2

在工程设置Command line中把/SUBSYSTEM:CONSOLE改为/SUBSYSTEM:WINDOWS

Answer 3

还有个笨办法：重建一个工程，在类型里选择Win32 Appcation,再输入代码。你肯定选的是Win32 Consle类型才出现这样的状况的。

Answer 4

看《Windows 程序设计》。看前四章就可以大概掌握了。

Answer 5

建错工程类型了，不要建console的工程，间win32 applications的工程
