The immediate problem is that you have missed out a quote:

VB

SavInto1.CommandText = "UPDATE PrintDetails set BaseFabricColor=" & "'" & TextBox3.Text & "'" & ",ArtWorkRef = " & "'" & TextBox4.Text & "'" & " WHERE OrderNo =" & "'" & TextBox1.Text & " AND PrintOn=" & "'" & TextBox2.Text & " '"

Should be

VB

SavInto1.CommandText = "UPDATE PrintDetails set BaseFabricColor='" & TextBox3.Text & "', ArtWorkRef = '" & TextBox4.Text & "' WHERE OrderNo ='" & TextBox1.Text & "' AND PrintOn='" & TextBox2.Text & "'"

But please don't do it like that!
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.
