C++中有四种强制类型转换:static_cast、dynamic_cast、reinterpret_cast和const_cast。 它们之间的区别和适用场景分别如下: 1. static_cast static_cast用于基本数据类型之间以及具有继承关系的指针或引用之间的类型转换,还可以用于隐式类型转换(例如将float转换为int)。此外,它还可以用于将void指针转换为任意其他类型指针。

static BOOL LoadResource(CWnd* pHostWnd, LPVOID lpResource, DWORD dwSize); 参数 pHostWnd 指向主机窗口的指针。 lpResource 指向包含 AFX_DIALOG_LAYOUT 资源的缓冲区的指针。 dwSize 缓冲区大小(以字节为单位)。 返回值 如果已加载资源并将其应用于主机窗口,则为 TRUE;否则为 FALSE。
C语言风格的强制转换:通过使用圆括号包围要转换的数据类型来实现强制类型转换。该转换与static_cast功能相似,但没有编译时或运行时的安全检查,因此可能会导致未定义行为。 总之,推荐使用safe_cast和dynamic_cast进行类型转换,以确保转换的安全性。而C语言风格的强制转换应该尽量避免使用。
