I’m a novice with my coding so forgive me if my question seems basic but I’m having some trouble extracting my variables from this While Loop in order to then use the results of my SQL query for validation.
This script below is the event handling for a login button on an .aspx form processing an email and login field that will be listed in a correlating MSSQL database:
Public Class _Default
Inherits System.Web.UI.Page
Protected Sub submit_Click(sender As Object, e As EventArgs) Handles submit.Click
Dim Column1 As String
Dim Column2 As String
Dim SQL = "SELECT * FROM Logins WHERE Email='" & email.Text & "' AND Password='" & password.Text & "'"
Dim oSqlDataReader As System.Data.SqlClient.SqlDataReader = Nothing
Using oSqlConnection As New System.Data.SqlClient.SqlConnection("SERVER=[Server Name];UID=[User];PWD=[Pass];DATABASE=[Database Name]")
oSqlConnection.Open()
Using oSqlCommand As New System.Data.SqlClient.SqlCommand(SQL, oSqlConnection)
oSqlDataReader = oSqlCommand.ExecuteReader
While oSqlDataReader.Read
Column1 = oSqlDataReader(name:="Email")
Column2 = oSqlDataReader(name:="Password")
End While
End Using
oSqlConnection.Close()
End Using
If "Column 1 etc....."
End if
End Sub
End Class
As far as I can tell my code is working with no errors but everytime I try and create an If statement my Variable ‘Column 1 and Column 2’ are undeclared making them useless.
If anyone could help with the correct layout for my code or missing areas and an explanation as to where I’ve gone wrong that’d be great.
