You didn't say what line was causing the error but for starters you should change

 cmd.CommandText = "UPDATE tblResidence " & _
                 ", ReId='" & Me.txtstdID.Text & "'" & _
                 ", Previous='" & Me.txtPrev.Text & "'" & _
                 ", Present='" & Me.txtPresent.Text & "'" & _
                 ", Reading='" & Me.txtRead.Text & "'" & _
                 ", Amount='" & Me.txtAmount.Text & "'" & _
                 ", Total_Amount='" & Me.txtTAmount.Text & "'" & _
                 ", Date='" & Me.txtDate.Text & "'" & _
                 " WHERE ReID=" & Me.txtstdID.Tag

to

 cmd.CommandText = "UPDATE tblResidence " & _
                 " "   SET ReId         = '" & txtstdID.Text & "'" & _
                 ",        Previous     = '" & txtPrev.Text & "'" & _
                 ",        Present      = '" & txtPresent.Text & "'" & _
                 ",        Reading      = '" & txtRead.Text & "'" & _
                 ",        Amount       = '" & txtAmount.Text & "'" & _
                 ",        Total_Amount = '" & txtTAmount.Text & "'" & _
                 ",        Date         = '" & txtDate.Text & "'" & _
                 "   WHERE ReID         =  " & txtstdID.Tag

but you should really be using parameterized queries. The link takes you to a thread with examples for both SqlClient and OLEDB. Note that it is not necessary to add "Me." to qualify all of your textbox controls.
