[_铭子_]

请问各位高手，当单击右键时，程序如何得到这个消息呢？
谢谢

添加OnTrayNotification()方法,然后加入响应代码就是了:

LRESULT CSystemTray::OnTrayNotification(UINT wParam, LONG lParam)
{
//Return quickly if its not for this tray icon
if (wParam != m_tnd.uID)
return 0L;

CMenu menu, *pSubMenu;
CWnd* pTarget = AfxGetMainWnd();

// Clicking with right button brings up a context menu
if (LOWORD(lParam) == WM_RBUTTONUP)//右键放开
{
if (!menu.LoadMenu(m_tnd.uID)) return 0;
if (!(pSubMenu = menu.GetSubMenu(0))) return 0;

// Make chosen menu item the default (bold font)
::SetMenuDefaultItem(pSubMenu->m_hMenu, m_DefaultMenuItemID, m_DefaultMenuItemByPos);

// Display and track the popup menu
CPoint pos;
GetCursorPos(&pos);

pTarget->SetForegroundWindow();
::TrackPopupMenu(pSubMenu->m_hMenu, 0, pos.x, pos.y, 0,
pTarget->GetSafeHwnd(), NULL);

// BUGFIX: See "PRB: Menus for Notification Icons Don't Work Correctly"
pTarget->PostMessage(WM_NULL, 0, 0);

menu.DestroyMenu();
}
else if (LOWORD(lParam) == WM_LBUTTONDBLCLK) //左键双击
{
// double click received, the default action is to execute default menu item
pTarget->SetForegroundWindow();

UINT uItem;
if (m_DefaultMenuItemByPos)
{
if (!menu.LoadMenu(m_tnd.uID)) return 0;
if (!(pSubMenu = menu.GetSubMenu(0))) return 0;
uItem = pSubMenu->GetMenuItemID(m_DefaultMenuItemID);
}
else
uItem = m_DefaultMenuItemID;

pTarget->SendMessage(WM_COMMAND, uItem, 0);

menu.DestroyMenu();
}

return 1;
}

希望对你有帮助

对不起,可能是系统问题(我的是繁体的WIN200),所以再说一次:

添加OnTrayNotification()方法,然后加入响应代码就是了

LRESULT CSystemTray::OnTrayNotification(UINT wParam, LONG lParam)
{
if (wParam != m_tnd.uID)
return 0L;

CMenu menu, *pSubMenu; //建立菜单对象
CWnd* pTarget = AfxGetMainWnd();

if (LOWORD(lParam) == WM_RBUTTONCLK)//如果右键单击显示菜单
{
if (!menu.LoadMenu(m_tnd.uID)) return 0;
if (!(pSubMenu = menu.GetSubMenu(0))) return 0;
::SetMenuDefaultItem(pSubMenu->m_hMenu, m_DefaultMenuItemID, m_DefaultMenuItemByPos);

CPoint pos;
GetCursorPos(&pos);
pTarget->SetForegroundWindow();
::TrackPopupMenu(pSubMenu->m_hMenu, 0, pos.x, pos.y, 0, pTarget->GetSafeHwnd(), NULL);
pTarget->PostMessage(WM_NULL, 0, 0);
menu.DestroyMenu();
}

return 1;
}


你可以先在资源编辑器里做一个菜单,也可以动态生成菜单.希望对你有帮助
