编译这段代码时:
#include <windows.h>
int WINAPI WinMain(HINSTANCE hInsance,HINSTANCE hPrevInstance,PSTR cmdLine,int showCmd){
MessageBox(0,"First Win32 Program","Window Tittle",MB_OK);
}
我收到编译器错误:
错误 C2664:'MessageBoxW':无法将参数 2 从 'const char [20]' 转换为 'LPCWSTR' 1> 指向的类型不相关;转换需要 reinterpret_cast、C-style cast 或 function-style cast
Error C2664: 'MessageBoxW': cannot convert parameter 2 from 'const char [20]' to 'LPCWSTR' 1> Types pointed to are unrelated; conversion requires reinterpret_cast, C-style cast or function-style cast
我做错了什么?
你定义了 UNICODE
,所以 MessageBox
需要一个宽字符串.
You have UNICODE
defined, so MessageBox
is expecting a wide string.
