    Win32 API tooltip control

    Hi all, I am trying to get a tooltip to work, for some reason it just will not pop up. I have followed the MSDN examples exactly. There is also a full example on FoosYerDoos, which when I compile it without changing any of the code, it still doesn't show them up. I am using VC++ 2008.

    Here is my code
    Code:
     INITCOMMONCONTROLSEX ic;
     ic.dwSize = sizeof(INITCOMMONCONTROLSEX);
     ic.dwICC = ICC_TAB_CLASSES;
     InitCommonControlsEx(&ic);
    
     tooltiphWnd = CreateWindowEx(WS_EX_TOPMOST, TOOLTIPS_CLASS, L"", WS_POPUP | TTS_NOPREFIX | TTS_ALWAYSTIP, 10, 10, 10, 10, mainhWnd, NULL, mainhInst, NULL);
    
      SetWindowPos(tooltiphWnd, HWND_TOPMOST, 0, 0, 0, 0, SWP_NOMOVE | SWP_NOSIZE | SWP_NOACTIVATE);
      TOOLINFO ti;
      ti.cbSize = sizeof(TOOLINFO);
      ti.uFlags = TTF_IDISHWND | TTF_SUBCLASS;
      ti.uId = (UINT_PTR)mainexitButton->GethWnd();
      ti.lpszText = L"This is a button.";
      ti.hwnd = mainhWnd;
    
      SendMessage(tooltiphWnd, TTM_ADDTOOL, 0, (LPARAM)&ti);
      SendMessage(tooltiphWnd, TTM_ACTIVATE, true, NULL);
    It should show up when I hover over my exit button. The weird thing is it doesn't work when I compile the FoosYerDoos example either, which makes me think that maybe I am not including something?

    Any help would be greatly appreciated.

    Seems to be an issue with vc2008 as earlier versions and other compilers don't produce the same problem. If the executable has a manifest for 'kiddie control styles' then the tooltip works as expected.

    If you'd like to add the manifest, add the following, including quotes, to project settings -->linker--> Manifest File-->additional dependencies:
    Code:
    "type='win32' name='Microsoft.Windows.Common-Controls' version='6.0.0.0' processorArchitecture='x86' publicKeyToken='6595b64144ccf1df' language='*'"
