    Hi, there,

    I know there are many questions whose names are quite similar to mine, but their answers don't meet my demand. My problem is:

    Now, I have created a notify icon in notification area, implemented the handler of WM_CONTEXTMENU message, so when I right click the notify icon, a context menu will popup. Then I want the first menu item of the context menu to be a owner-drawn one. I have already changed the flag of the first menu item with following code

    ModifyMenu(hmenu, menuItemId, MF_BYCOMMAND | MF_OWNERDRAW, menuItemId, (LPTSTR) this)

    And this function return correctly. 

    But in my windows main procedure, the WM_MEASUREITEM message is never received. 

    Is there any other configuration I miss? Or the owner of the context menu is not my main windows?

    Thanks in advance for any help.

    Cheers,

    Add Window call back function like this: 

    case WM_CONTEXTMENU:
		{
			POINT pt = {LOWORD(lParam), HIWORD(lParam)};
			HMENU hMenu = LoadMenu(hInst, MAKEINTRESOURCE(IDR_MENU1));
			if(NULL == hMenu)
			{
				return 0;
			}
			HMENU hSubMenu = GetSubMenu(hMenu, 0);
			
			int nCount = GetMenuItemCount(hSubMenu);
			UINT nID = 0;
			const UINT MAX_COUNT = 64;
			TCHAR szText[MAX_COUNT] = {0};
			for(int i=0; i<nCount; i++)
			{
				nID = GetMenuItemID(hSubMenu, i);
				if((-1 != nID) && (0 != nID))
				{
					GetMenuString(hSubMenu, nID, szText, MAX_COUNT, MF_BYCOMMAND);
					ModifyMenu(hSubMenu, nID, MF_BYCOMMAND | MF_OWNERDRAW, nID, szText);
				}
			}
			TrackPopupMenu(hSubMenu, TPM_LEFTALIGN | TPM_RIGHTBUTTON, pt.x, pt.y, NULL, hWnd, NULL);
			DestroyMenu(hMenu);
		}
		break;
	case WM_MEASUREITEM:
		{
			static int i = 0;
			TCHAR buf[32] = {0};
			_stprintf(buf, _T("MenuItem: %d"), ++i);
			MessageBox(hWnd, buf, _T("Message"), 0);
		}
		break;
