MFC 怎么将窗口句柄转化成窗口指针

主对话框创建子对话框，我想在主对话框中调用子对话框的函数来操作子对话框

Answer 1

貌似创建子对话框的时候主对话框类里是有个成员变量的 这个成员变量 就是子窗口类的指针

CWnd::FromHandle

static CWnd* PASCAL FromHandle( HWND
hWnd ); 用它 再加个 指针类型强制转换

Return Value

Returns a pointer to a CWnd object when given a handle to a window. If
a CWnd object is not attached to the handle, a temporary CWnd
object is created and attached.

The pointer may be temporary and should not be stored for later use.
