晕，那样能得到才奇怪呢<br>LB_GETTEXT的调用规则：<br>An application sends an LB_GETTEXT message to retrieve a string from a list box. <br><br>LB_GETTEXT <br>wParam = (WPARAM) index; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;// item index <br>lParam = (LPARAM) (LPCTSTR) lpszBuffer; // address of buffer <br>不过在其它程序中，也许需要注入DLL解决指针问题
