???public void widgetSelected(final SelectionEvent e) {
????
????String sname = name.getText();
????String spwd = pwd.getText();

????try {
?????Class.forName("sun.jdbc.odbc.JdbcOdbcDriver");
?????Connection con = DriverManager.getConnection(
???????"jdbc:odbc:test", "", "");
?????Statement stmt = con.createStatement();
?????ResultSet rs = stmt
???????.executeQuery("select * from userid where name='"+sname+"'and psw='"+spwd+"'");

?????if (rs.next()) {
??????MessageDialog.openInformation(shell, "",
????????"謝謝你的登錄!你是合法用戶!");
?????} else {
??????MessageDialog.openInformation(shell, "",
????????"請你正確登錄!用戶名或密碼不正確!");
?????}

?????rs.close();
?????stmt.close();
?????con.close();
????} catch (Exception e1) {
?????e1.printStackTrace();
????}

???}
