为什么在程序中加入了MOVETO 在编译时没有出错，但是在连接时就出错了？（附程序完整代码！）

Answer 1

确保包含这些库
kernel32.lib user32.lib gdi32.lib winspool.lib comdlg32.lib advapi32.lib shell32.lib ole32.lib oleaut32.lib uuid.lib odbc32.lib odbccp32.lib

Answer 2

不是MoveToEx吗？
楼主为什么要用MoveTo？好像没有这个函数哦！

Answer 3

MoveToEx试一下
MoveTo是windows3.X下的.

Answer 5

你改一下版本
#define WINVER 0X300

Answer 6

#define WINVER 0X300
 是什么意思？？？
