because i need to distribution memory to write something, if memory is not enough, tip to user

please post your code

i already find the reason, beacause

"
m_menu.LoadMenuW(IDR_MENU);

dlg.SetMenu(&m_menu);
"

should be put in Dialog InitDialog method;

How can insert menu to dialog by ce application?

CMenu m_menu;

m_menu.LoadMenuW(IDR_MENU_MAIN);

CMyCEApplicationDlg dlg;
m_pMainWnd = &dlg;

dlg.SetMenu(&m_menu);

RunTime the code "dlg.SetMenu(&m_menu);" is error.
