// Description://   Creates a tooltip for an item in a dialog box. // Parameters://   idTool - identifier of an dialog box item.//   nDlg - window handle of the dialog box.//   pszText - string to use as the tooltip text.// Returns://   The handle to the tooltip.//HWND CreateToolTip(int toolID, HWND hDlg, PTSTR pszText){    if (!toolID || !hDlg || !pszText)    {        return FALSE;    }    // Get the window of the tool.    HWND hwndTool = GetDlgItem(hDlg, toolID);        // Create the tooltip. g_hInst is the global instance handle.    HWND hwndTip = CreateWindowEx(NULL, TOOLTIPS_CLASS, NULL,                              WS_POPUP |TTS_ALWAYSTIP | TTS_BALLOON,                              CW_USEDEFAULT, CW_USEDEFAULT,                              CW_USEDEFAULT, CW_USEDEFAULT,                              hDlg, NULL,                               g_hInst, NULL);       if (!hwndTool || !hwndTip)   {       return (HWND)NULL;   }                                                                // Associate the tooltip with the tool.    TOOLINFO toolInfo = { 0 };    toolInfo.cbSize = sizeof(toolInfo);    toolInfo.hwnd = hDlg;    toolInfo.uFlags = TTF_IDISHWND | TTF_SUBCLASS;    toolInfo.uId = (UINT_PTR)hwndTool;    toolInfo.lpszText = pszText;    SendMessage(hwndTip, TTM_ADDTOOL, 0, (LPARAM)&toolInfo);    return hwndTip;}
