Hi guys,

I am developing a music library application in visual studio using C#. I have crated a login form which will be showing the "user form" after successful login. In the login form i am using "Id" and "Password" . In sql server database there is name related to each Ids.

I want to show on "User" form something like "Welcome : User Name"

My question is how can I show the name on User form after logging in with ID from LogIn form . Any process to retrieve the name from sql server and show it in User form??

Please help.

Thank you..

Hai,

In your login click read the particular id details in database then save the username of given id to Session variable,like this..

obj.readvalue(str);//read your table using given password and userid
//save the particular id username into session
Session["Username"] = obj.username;

So when you are Checking UserID and password you can get username as well if ID and password is fine from db and store it in Global variable/Session Variable and you can use it.

Hi..

You can use session variables...

Eg -
say on Login button click event -

if - login is successful
session["username"] = txt_Username.text.trim();
---
Then...

string s = "Welcome"+"\t"+ session["username"].ToString().Trim();

There are different ways You can store username in session if login is successful and you can fetch it after login from that session variable.
