如何从父窗口句柄获得子窗口的控件的句柄？？

[张大宝]

我做的是一个网络通信客户端，用一个单独的文件Exchange.h来处理接收信息，然后在这个文件中获得句柄，给子窗口的控件附值。比如：Exchange.h收到聊天信息，然后把聊天信息显示在客户端的一个切分窗口的Edit控件上。但是我在Exchange.h只能获得主框架窗口的句柄，得不到子窗口句柄和控件句柄。下面是我的代码。
HWND hMainFrame = ::FindWindow("CMainFrame",NULL);
HWND hMEG = ::FindWindowEx(hMainFrame,NULL,"CMegFormView",NULL);
HWND hLIST = ::FindWindowEx(hMEG,NULL,"CListBox",NULL);

得不到hMEG和hLIST阿。
请高手帮帮忙。

试试这样吧:
给这个控件设一个类:CReadEdit, 继承自CEditView
CMainFrame* pFrame = (CMainFrame*)AfxGetMainFrame();
CXXDoc* pDoc = (CXXDoc*)pFrame->GetActiveDocument();
POSITION pos = pDoc->GetFirstViewPosition();
while(pos != NULL)
{
CView* pView = pDoc->GetNextView(pos);
if(pView != NULL)
{
if(pView->IsKindOf(RUNTIME_CLASS(CReadEdit)))
{
CReadEdit* pEdit = (CReadEdit*)pView;
if(pEdit)
{
CString sMsg = _T("hello.");
pEdit->GetEditCtrl().SetWindowText(sMsg);
}
}
}
}

得到主窗口指针后再访问它的成员变量m_splitterwnd。然后用GetPane函数得到CMegFormView。得到了CMegFormView的指针后再枚举他的子控件。
//pWnd指向CMegFormView
CWnd *pwnd=pWnd->GetWindow(GW_CHILD);
while(pwnd!=NULL)
{
GetClassName(...);
pwnd = pwnd->GetNextWindow();
}

试试这个
GetWindow
The GetWindow function retrieves a handle to a window that has the specified relationship (Z order or owner) to the specified window.

HWND GetWindow(
HWND hWnd, // handle to original window
UINT uCmd // relationship flag
);

Parameters
hWnd
Handle to a window. The window handle retrieved is relative to this window, based on the value of the uCmd parameter.
uCmd
Specifies the relationship between the specified window and the window whose handle is to be retrieved. This parameter can be one of the following values: Value Meaning
GW_CHILD The retrieved handle identifies the child window at the top of the Z order, if the specified window is a parent window; otherwise, the retrieved handle is NULL. The function examines only child windows of the specified window. It does not examine descendant windows.
GW_ENABLEDPOPUP Windows NT 5.0 and later: The retrieved handle identifies the enabled popup window owned by the specified window (the search uses the first such window found using GW_HWNDNEXT); otherwise, if there are no enabled popup windows, the retrieved handle is that of the specified window.
GW_HWNDFIRST The retrieved handle identifies the window of the same type that is highest in the Z order. If the specified window is a topmost window, the handle identifies the topmost window that is highest in the Z order. If the specified window is a top-level window, the handle identifies the top-level window that is highest in the Z order. If the specified window is a child window, the handle identifies the sibling window that is highest in the Z order.
GW_HWNDLAST The retrieved handle identifies the window of the same type that is lowest in the Z order. If the specified window is a topmost window, the handle identifies the topmost window that is lowest in the Z order. If the specified window is a top-level window, the handle identifies the top-level window that is lowest in the Z order. If the specified window is a child window, the handle identifies the sibling window that is lowest in the Z order.
GW_HWNDNEXT The retrieved handle identifies the window below the specified window in the Z order. If the specified window is a topmost window, the handle identifies the topmost window below the specified window. If the specified window is a top-level window, the handle identifies the top-level window below the specified window. If the specified window is a child window, the handle identifies the sibling window below the specified window.
GW_HWNDPREV The retrieved handle identifies the window above the specified window in the Z order. If the specified window is a topmost window, the handle identifies the topmost window above the specified window. If the specified window is a top-level window, the handle identifies the top-level window above the specified window. If the specified window is a child window, the handle identifies the sibling window above the specified window.
GW_OWNER The retrieved handle identifies the specified window's owner window, if any.

可以得到。。。
我只能告诉你查SDK文档，FindWindow函数。。

你知道这个edit控件id就可以了
如：

CEdit* pBoxOne;
pBoxOne = (CEdit*) GetDlgItem(IDC_EDIT1);
