如何改变系统菜单？

[niya3]

比如说：把菜单里的“新建”改成“打开”！

怎么让新建的子窗口全屏

[niya3]

我说的是控制系统菜单！

还没入门，能具体点吗？比如说我想让子窗口全屏，怎么改？

[niya3]

wuxuan(真心英雄)：

我看看！
我出去一会儿，问题解决了，今天一定给分！

[niya3]

具体点吧！

如何把“窗口”---“层叠”项换成平铺功能！

[jesion]

void CChildFrame::ActivateFrame(int nCmdShow)
{

CMDIChildWnd::ActivateFrame(SW_SHOWMAXIMIZED);
}
//这个是让子窗口最大化的方法
需要通过传递CChildFrame类中的消息ActivateFrame函数来实现。

[niya3]

最大化不行，没法子平铺窗口！
就是实现平铺子窗口！我找不见系统菜单的功能在那里修改！

[niya3]

等待有人回答！

[niya3]

服务器可真忙！

[jesion]

void CChildFrame::ActivateFrame(int nCmdShow)
{

CMDIChildWnd::ActivateFrame(SW_SHOWMAXIMIZED);
}
//这个是让子窗口最大化的方法
需要通过传递CChildFrame类中的消息ActivateFrame函数来实现。
多文档的程序子窗口就是这样最大化的,调试通过...
不行????你试了??

[闻缺陷则喜何志丹]

AfxGetApp()->GetMainWnd()->SetMenu(...);

今天一直进不来，我试试！

最大化行，我是说要平铺窗口！

[niya3]

我怎么不能留言！

[daniceexiedong]

要想改住菜单，直接改它的消息接收函数，两个互换就可以了！

在子框架的PreCreateWindow()中加入cs.style |= WS_VISIBLE | WS_MAXIMIZE;
