Vista "glossy text" effect

[bojan.dosen]

Hi,
I'm searching on the Internet how to draw glossy text (text effect like in window title bar in Vista) in window with DrawThemeText or DrawThemeTextEx but I don't understand! It's for C++: <link>. Can you help me?
Thanks!

Yeah, I can't stand the CodeProject, they do everything within their own little format.

Here is a short C tutorial from the original documentation.

The WinAPI is a pain in the butt, ain't it.

I don't understand this part:

Code: Select all

if ((message == WM_NCCALCSIZE) && (wParam == TRUE))
    {
        // Calculate new NCCALCSIZE_PARAMS based on custom NCA inset.
        NCCALCSIZE_PARAMS *pncsp = reinterpret_cast<NCCALCSIZE_PARAMS*>(lParam);

        pncsp->rgrc[0].left   = pncsp->rgrc[0].left   + 0;
        pncsp->rgrc[0].top    = pncsp->rgrc[0].top    + 0;
        pncsp->rgrc[0].right  = pncsp->rgrc[0].right  - 0;
        pncsp->rgrc[0].bottom = pncsp->rgrc[0].bottom - 0;

        lRet = 0;
        // No need to pass message on to the DefWindowProc.
        fCallDWP = false;
    }

Can someone explain?

It doesn't appear to do anything, but if you're wondering what "reinterpret_cast" is, it's just an unsafe cast. If you use CPtr(NCCALCSIZE_PARAMS Ptr, lParam), you'll have the same effect.
