最终问题出在不是强制类型转换上,而是
1。char count[6]; 改成wchar count[6];
2.把m_CharNumber.SetWindowTextW(count); 改成
m_CharNumber.SetWindowText(count);把W去掉,还有些类似的函数都要去掉,在项目(project)->属性(property)中通常(general)中有个字符选项(我是英文版的,中文叫什么我不知道,不知道你什么版本),里面有选用多字节还是Unicode改成多字节(Multi-Byte)
使用第2中方法中在项目(project)->属性(property)中通常(general)中有个字符选项(我是英文版的,中文叫什么我不知道,不知道你什么版本),里面有选用多字节还是Unicode改成多字节(Multi-Byte)
