static LRESULT __stdcall ChangeCaptions(int nCode, WPARAM wParam, LPARAM lParam)
{
    if (nCode == HCBT_ACTIVATE) {
        SetWindowText(GetDlgItem((HWND) wParam, IDOK), L10N(GUI_OK_MSG));
        SetWindowText(GetDlgItem((HWND) wParam, IDCANCEL), L10N(GUI_CANCEL_MSG));
        SetWindowText(GetDlgItem((HWND) wParam, IDYES), L10N(GUI_YES_MSG));
        SetWindowText(GetDlgItem((HWND) wParam, IDNO), L10N(GUI_NO_MSG));
    }
    return 0;
}

int addon_gui_messagebox(HWND parentHWnd, HINSTANCE hInstance, void *text, void *caption, int type)
{
    int ret;
    hook = SetWindowsHookEx(WH_CBT, ChangeCaptions, hInstance, GetCurrentThreadId());
    ret = MessageBox(parentHWnd, text, caption, type);
    UnhookWindowsHookEx(hook);
    return ret;
