insert a break point to button_click event handler and then run the application in the debug mode, make sure to see if all the lines are executed. or attach your solution as zip file so we can test to see what's going on.

Look at the output window after you click the button. Do you see an exception similar to:

A first chance exception of type 'System.Data.SqlClient.SqlException' occurred in System.Data.dll

Use bb code tags.

Look at bin folder's database1.mdf.

Hi

This Code is very useful to display data from textbox to sqldatabase

OnButton Click

Dim sqlStmt As String
Dim conString As String
Dim cn As Sqlconnection (Won't reconize SQL connection)
Dim cmd As SqlCommand (Won't reconize SQL command)
Try
sqlStmt = "insert into Table1 (FName) Values (@Fname) "
conString = "Server and connection here is correct;"
cn = New SqlConnection(conString)
cmd = New SqlCommand(sqlStmt, cn)
cmd.Parameters.Add(New SqlParameter("@FName", SqlDbType.NVarChar, 11))
cmd.Parameters("@FName").Value = TxtBoxNewRN.Text
cn.Open()
cmd.ExecuteNonQuery()
Finally
cn.Close()
End Try
