To designate a block of five rows, we define three rows (consisting of a td element spanning three columns): Roll 101-105, Roll 106-110, and Roll 111-115. These rows (td element spanning three columns) are assigned the class name studgroup so as to identify and use them in jQuery. To highlight the rows, we define a style rule .hover in the style sheet file. The style sheet file style.css is shown here: style.css .hover { background-color: #00f; color: #fff; } The jQuery code to expand hidden rows when their corresponding row is hovered over is shown here: $(document).ready(function() { $('table tbody tr').hide(); $('table tbody').find('.studgroup').parent().show(); $('tbody tr').hover( function(){ var tr=$('table tbody tr'); var rindex=$(this).parent().children().index(this); for(var i=rindex;i<=rindex+5;i++) { asp.net ean 13, java pdf 417 reader, winforms ean 13 reader, free code 128 font crystal reports, c# code 128 auto, data matrix reader .net java barcode library open source Java Barcode Generation & Recognition API - Export Barcodes to ...

The Oracle and MySQL databases (and some other databases such as Sybase) support transactions; meanwhile, the Microsoft Access database does not support transactions. The following code presents the general solution, and then I will show how to test the solution against Oracle and MySQL databases. import java.sql.Connection; import java.sql.DatabaseMetaData; import jcb.util.DatabaseUtil; ... Connection conn = null; try { conn = <get-a-database-connection>; DatabaseMetaData dbMetaData = conn.getMetaData(); if (dbMetaData.supportsTransactions()) { // Transactions are supported } else { // Transactions are not supported } } catch (SQLException e) { // handle the exception: // could not determine if database // server supports transactions } finally { DatabaseUtil.close(conn); } $(tr[i]).show(); } $(this).addClass('hover'); }, function(){ $('table tbody tr').hide(); $('table tbody').find('.studgroup').parent().show(); $(this).removeClass('hover'); } ); }); java barcode reader library download QR Code Scanner - Barcode Scanner for Android - JournalDev
