As I told you 15 minutes ago: ID IS bigint. while compiling it is showing some problem in textbox1.text[^] do not concatenate strings to build a SQL command. It leaves you wide open to accidental or deliberate SQL Injection attack which can destroy your entire database. Use Parametrized queries instead.

An example would be:

VB

Using con As New SqlConnection(strConnect)
    con.Open()
    Using com As New SqlCommand("INSERT INTO myTable (myColumn1, myColumn2) VALUES (@C1, @C2)", con)
        com.Parameters.AddWithValue("@C1", myValueForColumn1)
        com.Parameters.AddWithValue("@C2", myValueForColumn2)
        com.ExecuteNonQuery()
    End Using
End Using
