Hi,

I have some source from http://www.relisoft.com/ (great place for Win32), but I can't compile them under RSXNTDJ. Probably problem is in templates :

Functions are defined like this :
template <class T>
inline T GetWinLong (HWND hwnd, int which = GWL_USERDATA)
{
    return reinterpret_cast<T> (GetWindowLong (hwnd, which));
}

template <class T>
inline void SetWinLong (HWND hwnd, T value, int which = GWL_USERDATA)
{
    SetWindowLong (hwnd, which, reinterpret_cast<long> (value));
}

and later used :

.....(code fragment)

	// Pointer to Controller is stored in Window
    Controller * pCtrl = GetWinLong<Controller *> (hwnd);		// line a

    switch (message)
    {
    case WM_CREATE:
        try
        {
            pCtrl = new Controller (hwnd, (CREATESTRUCT *) lParam);
			// Store pointer to Controller inside Window
            SetWinLong<Controller *> (hwnd, pCtrl);			// line b
        }

during compile I.ve got a messages (for line a, b and other) :

parse error before '*'

Is it standard template construction or VC++ specific?

Thanks.

Ps. Sorry for my English.
