Question

这个程序与win32编程中的Window Assets有关。当我执行它时，不是用英文打印出“在这里插入文本......”，而是用中文或日文打印出来。为什么呢？

#include "stdafx.h"
#include "Window-Assets.h"
#include <windows.h>
#define IDC_MAIN_BUTTON 101         // Button identifier
#define IDC_MAIN_EDIT   102         // Edit box identifier

Answer 1

似乎您的应用程序被定义为Unicode（=期望获得const wchar_t*个字符串），并且您在此行中发送了一些ASCII字符串（const char*）：

(LPARAM)"Insert text here...");

尝试将其更改为：

(LPARAM)L"Insert text here...");

Answer 2

你可以替换（LPARAM）“在这里插入文字......”）; 通过（LPARAM）TEXT（“在此处插入文字......”））; 检查windows TEXT宏。

为什么win32代码中的Window资产以中文或日文而不是英文打印？
