Don't form a sql string, use parametrized query.

..
com.CommandText = "update BCA2 set [Rollno]= " & trollno.Text & ",[Stu_Name]='" & tname.Text & "', [FORTRAN]= " & tfor.Text & ", [Data Structures]= " & tds.Text & ", [Oracle]=" & toracle.Text & ", [C++]=" & tcpp.Text & ", [Unix] = " & tunix.Text & " , [Lab1] = " & tlab1.Text & ", [Lab2] = " & tlab2.Text & " where [Rollno] = " & ComboBox1.Text
