Hello everyone,

I just started working with .net and need to create a simple login page. I have the design page but am struggling with the code behind. This is what I have so far. Alot of it is what I got from samples over the net. Below are the errors I'm getting when compiling it. I am not familiar with the commands for sqlclient so am not able to figure out what is wrong here. Any help would be appreciated.

Thanks,
Kathy

hi kathy,

There is an error in ur code if u notice.

System.Data.SqlClient.SqlDataAdapter SqlCmd=new System.Data.SqlClient.SqlDataAdapter("Select * From Person Where Username='" +
UserName.Text + "' And Password = '" +
Password.Text + "'");


SqlCmd.Fill( ds );


The error which u get

'System.Data.SqlClient.SqlDataAdapter' is a 'type', which is not valid in the given context.

explains that sqldataadapter is a type.u have not created an object for the type and the type sqldataadapter cannot be used as such.

Secondly,
The name 'SqlCmd' does not exist in the current context.

U have used SqlCmd here but u have not delcared it.

Hope you understand.

Thanks

Use parameters in SQL query, do not use direct insertion in query.
