推荐答案

你好Viswanthan，


您已创建用于插入数据的连接.然后使用该连接从数据表中的数据库存储中检索数据，并检查用户名和密码.如果匹配，则显示下一个窗口，否则显示消息，提示用户名密码错误.

您可以在登录按钮单击事件上做的所有事情



谢谢

hello Viswanthan,


you have created connection to insert the data. then use that connection to retrieve the data from ur DB store in Data table and check against ur username and password. if it matches then show the next window else show the message that username password is wrong.

this all you can do on login button click event



thanks

取决于您存储用户名和密码的位置(数据库，文件等) .

您需要编写逻辑，以便它检查此存储，然后仅在密码匹配时登录.

Depends on where you are storing your username and password (database, file etc).

You need to write your logic so that it checks against this store and then login only if the password matches.
