子窗口如何动态创建控件CWND指针如何获取

[wjm1990]

单文档视图分割弄了很多子对话框，现在相对子对话框动态添加控件
CWND*用的是AfxGetMainWnd()，所以控件都添到视图里了，没在子对话框上
应该怎么操作

[sumos]

把子对话框记录下来， std::map<std::wstring, CDialogEx*> windows_; 根据id去找到对应的对话框，然后在对话框上创建CWND。

AfxGetMainWnd返回的不是框架主窗口指针就是活动视图指针，你网对画框添加控件，需要对话框的指针，对话框是你自己创建的，你应该在创建他们的时候把它们的指针保存起来，这样你才能动态创建子控件的时候对号入座

我用的creatview创建视图，这个怎么操作

FindWindowEx The FindWindowEx function retrieves a handle to a window whose class name and window name match the specified strings. The function searches child windows, beginning with the one following the given child window. This function does not perform a case-sensitive search. HWND FindWindowEx( HWND hwndParent, // handle to parent window HWND hwndChildAfter, // handle to a child window LPCTSTR lpszClass, // pointer to class name LPCTSTR lpszWindow // pointer to window name ); Parameters hwndParent Handle to the parent window whose child windows are to be searched. If hwndParent is NULL, the function uses the desktop window as the parent window. The function searches among windows that are child windows of the desktop. Windows NT 5.0 and later: If hwndParent is HWND_MESSAGE, the function searches all message-only windows. hwndChildAfter Handle to a child window. The search begins with the next child window in the Z order. The child window must be a direct child window of hwndParent, not just a descendant window. If hwndChildAfter is NULL, the search begins with the first child window of hwndParent. Note that if both hwndParent and hwndChildAfter are NULL, the function searches all top-level and message-only windows. lpszClass Pointer to a null-terminated string that specifies the class name or is an atom that identifies the class-name string. If this parameter is an atom, it must be a global atom created by a previous call to theGlobalAddAtom function. The atom, a 16-bit value, must be placed in the low-order word of lpszClass; the high-order word must be zero. lpszWindow Pointer to a null-terminated string that specifies the window name (the window's title). If this parameter is NULL, all window names match. Return Values If the function succeeds, the return value is a handle to the window that has the specified class and window names. If the function fails, the return value is NULL. To get extended error information, callGetLastError. QuickInfo Windows NT: Requires version 4.0 or later. Windows: Requires Windows 95 or later. Windows CE: Unsupported. Header: Declared in winuser.h. Import Library: Use user32.lib. Unicode: Implemented as Unicode and ANSI versions on Windows NT.

你把对话框指针保存在数组里这个不困难吧，这个数组你搞成全局变量都可以
