sqlQuery = "insert into voucher(VoucherName, Account_Code, Amount)
values ('" & TxtVoucher & "', " & TxtAmount & ", '" & TxtAccount & "')"

Change the above line to this:

sqlQuery = _
"insert into voucher(VoucherName, Account_Code, Amount) values ('" & _
TxtVoucher.Text & "', " & TxtAmount.Text & ", '" & TxtAccount.Text & _
"')"
