一个典型的vc++智能电表校表软件应用程序源码 some code here: switch (wParam) { case NM_OB_ITEMCLICK: // cast the lParam to an integer to get the clicked item { int index = (int) lParam; CString cs, cs1; cs1 = wndBar.GetItemText(index); cs.Format("Clicked on %d - <%s>", (int)lParam, cs1); // AfxMessageBox(cs); // AfxMessageBox(cs1); if (cs1=="允许校表") { yu_allowxb(); } if (cs1=="清校表数据") { yu_clearmeter(); } if (cs1=="禁止校表") { yu_noxb(); }
