QA: How can I insert menu in a dialog?

Question
In VC I can edit dialog's menu in a resource editor. I cannot find menu editing
in eVC dialog resource editor. How can I use menu in dialogs?
Answer
In eVC menu is not a part of a window but is a separate control that takes
place in the client area and has its own handle. There are several ways to add
menu into a dialog.
Using CCeCommandBar class
MFC dialogs have built-in command bar (read more). You can insert menu using InsertMenuBar
method of this command bar. The best place to insert menu into a dialog is OnInitDialog method.
<![CDATA[
CCeCommandBar *pCommandBar = (CCeCommandBar*)m_pWndEmptyCB;
pCommandBar->InsertMenuBar(IDR_MENUBAR);
]]>
Using SHCreateMenuBar function
Since Pocket PC Windows CE provides SHCreateMenuBar function for adding a menu
to a window. Here is a sample of using this funtion:
<![CDATA[
SHMENUBARINFO info;
info.cbSize = sizeof(info);
info.hwndParent = m_hWnd;
info.dwFlags = 0;
info.nToolBarId = IDR_MENUBAR;
info.hInstRes = ::AfxGetInstanceHandle();
info.nBmpId = 0;
info.cBmpImages = 0;
SHCreateMenuBar(&info);
]]>
Sample
You can download a sample project (27 Kb) that demonstrates using menus
if dialogs. The most important part of this project is OnInitDialog method of the dialog.
Here it is:
<![CDATA[
BOOL CMenuInDialogDlg::OnInitDialog()
{
CDialog::OnInitDialog();
// Set the icon for this dialog. The framework does this automatically
// when the application's main window is not a dialog
SetIcon(m_hIcon, TRUE); // Set big icon
SetIcon(m_hIcon, FALSE); // Set small icon
CenterWindow(GetDesktopWindow()); // center to the hpc screen
//The first way. Using CCeCommandBar class.
CCeCommandBar *pCommandBar = (CCeCommandBar*)m_pWndEmptyCB;
pCommandBar->InsertMenuBar(IDR_MENUBAR);
/*
//The second way. Using SHCreateMenuBar function.
SHMENUBARINFO info;
info.cbSize = sizeof(info);
info.hwndParent = m_hWnd;
info.dwFlags = 0;
info.nToolBarId = IDR_MENUBAR;
info.hInstRes = ::AfxGetInstanceHandle();
info.nBmpId = 0;
info.cBmpImages = 0;
SHCreateMenuBar(&info);
*/
return TRUE; // return TRUE unless you set the focus to a control
}
