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:
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
