Multiple File Uploader C# Asp.Net (Jumploader)
Before few days i was developed a website where i was used asp.net file upload control. But the limitation is that user can select only single file at a time.But we require a file uploader with
- Multiple File Selection (i.e. user can select multiple files to upload)
- User can select only allowable Files (i.e. we can configure the file extention to upload)
- Auto update when all files uploaded
- It must be free control
I was tried a lot to find such file uploader and i was found that many multiple file uploader available with above mentioned features. But i like a JumpLoader
which is very useful and easy to use.
JumpLoader is a Java applet designed to upload files from the client to a server.
This is a valuable replacement for <input type=”file”>
you can read more about JumpLoader at www.jumploader.com
I was used jumploader in my project with c# Asp.Net.
How to use Jumploader with Asp.Net
UI
We used follow http handler to upload the files.

Bricks manufacturing
A brick is a block of ceramic material used in masonry construction, usually laid using various kinds of mortar.
History
The oldest discovered bricks, originally made from shaped mud and dating to 7500 B.C., were found in in the upper Tigris region and in southeast Anatolia close to Diyarbakir. Other more recent findings, dated between 7,000 and 6,395 B.C., come from Jericho and Catal Hüyük. The first sun-dried bricks were made in Mesopotamia (what is now Iraq), in the ancient city of Ur in about 4000 BC, although the arch used for drying the bricks was not actually found.
Other examples of civilizations who used mud brick include the ancient Egyptians and the Indus Valley Civilization, where it was used exclusively. In particular, it is evident from the ruins of Buhen, Mohenjo-daro and Harappa.
The trend of building upwards for offices that emerged towards the beginning of the 19th century displaced brick in favor of cast and wrought iron and later steel and concrete. Some early ‘skyscrapers’ were made in masonry, and demonstrated the limitations of the material – for example, the Monadnock Building in Chicago (opened in 1896) is masonry and just seventeen stories high; the ground walls are almost 6 feet (1.8 m) thick, clearly building any higher would lead to excessive loss of internal floor space on the lower floors. Brick was revived for high structures in the 1950s following work by the Swiss Federal Institute of Technology[disambiguation needed] and the Building Research Establishment in Watford, UK. This method produced eighteen-story structures with bearing walls no thicker than a single brick (150–225 mm). This potential has not been fully developed because of the ease and speed in building with other materials; in the late-20th century brick was confined to low- or medium-rise structures or as a thin decorative cladding over concrete-and-steel buildings or for internal non-load-bearing walls.
Methods of manufacture
Bricks may be made from clay, shale, soft slate, calcium silicate, concrete, or shaped from quarried stone.
Clay is the most common material, with modern clay bricks formed in one of three processes – soft mud, dry press, or extruded.
Normally, brick contains the following ingredients:
- Silica (sand) – 50% to 60% by weight
- Alumina (clay) – 20% to 30% by weight
- Lime – 2 to 5% by weight
- Iron oxide – 5 to 6% (not greater than 7%) by weight
- Magnesia – less than 1% by weight
- Clay Bricks
The soft mud method is the most common, as it is the most economical. It starts with the raw clay, preferably in a mix with 25-30% sand to reduce shrinkage. The clay is first ground and mixed with water to the desired consistency. The clay is then pressed into steel moulds with a hydraulic press. The shaped clay is then fired (“burned”) at 900-1000 °C to achieve strength.
- Rail kilns
In modern brickworks, this is usually done in a continuously fired tunnel kiln, in which the bricks move slowly through the kiln on conveyors, rails, or kiln cars to achieve consistency for all bricks. The bricks often have added lime, ash, and organic matter to speed the burning.
- Bull’s Trench Kilns
In India, brick making is typically a manual process. The most common type of brick kiln in use there are Bull’s Trench Kiln (BTK), based on a design developed by British engineer W. Bull in the late nineteenth century.
An oval or circular trench, 6–9 meters wide, 2-2.5 meters deep, and 100–150 meters in circumference, is dug. A tall exhaust chimney is constructed in the centre. Half or more of the trench is filled with “green” (unfired) bricks which are stacked in an open lattice pattern to allow airflow. The lattice is capped with a roofing layer of finished brick.
In operation, new green bricks, along with roofing bricks, are stacked at one end of the brick pile; cooled finished bricks are removed from the other end for transport. In the middle the brick workers create a firing zone by dropping fuel (coal, [wood], oil, debris, etc.) through access holes in the roof above the trench.
- Dry pressed bricks
The dry press method is similar to Clay brick but starts with a much thicker clay mix, so it forms more accurate, sharper-edged bricks. The greater force in pressing and the longer burn make this method more expensive.
- Calcium silicate bricks (Fly ash Bricks)
The raw materials for calcium silicate bricks include lime mixed with quartz, crushed flint or crushed siliceous rock together with mineral colourants. The materials are mixed and left until the lime is completely hydrated, the mixture is then pressed into moulds and cured in an autoclave for two or three hours to speed the chemical hardening. The finished bricks are very accurate and uniform, although the sharp arrises need careful handling to avoid damage to brick (and brick-layer). The bricks can be made in a variety of colours, white is common but pastel shades can be achieved.
It is very common in Sweden, especially in houses built or renovated in the ’70s. Here it is referred to as “Mexitegel” (en: Mexi[can] Bricks).
In India these are known as Fly ash bricks, manufactured using the Falg process.
Optimal dimensions, characteristics, and strength
For efficient handling and laying bricks must be small enough and light enough to be picked up by the bricklayer using one hand (leaving the other hand free for the trowel). Bricks are usually laid flat and as a result the effective limit on the width of a brick is set by the distance which can conveniently be spanned between the thumb and fingers of one hand, normally about four inches (about 100 mm). In most cases, the length of a brick is about twice its width, about eight inches (about 200 mm) or slightly more. This allows bricks to be laid bonded in a structure to increase its stability and strength (for an example of this, see the illustration of bricks laid in English bond, at the head of this article). The wall is built using alternating courses of stretchers, bricks laid longways and headers, bricks laid crossways. The headers tie the wall together over its width.
A hastily-made wall of rough bricks without using cement or even mud in an Indian town. Only plainest type of bricks are used in India. Such constructions are often risky
A bigger brick makes for a thicker (and thus more insulating) wall. Historically, this meant that bigger bricks were necessary in colder climates (see for instance the slightly larger size of the Russian brick in table below), while a smaller brick was adequate, and more economical, in warmer regions. A notable illustration of this correlation is the Green Gate in Gdansk; built in 1571 of imported Dutch brick, too small for the colder climate of Gdansk, it was notorious for being a chilly and drafty residence. Nowadays this is no longer an issue, as modern walls typically incorporate specialized insulation materials.
The correct brick for a job can be picked from a choice of colour, surface texture, density, weight, absorption and pore structure, thermal characteristics, thermal and moisture movement, and fire resistance.
Use
Bricks are used for building and pavement. In the USA, brick pavement was found incapable of withstanding heavy traffic, but it is coming back into use as a method of traffic calming or as a decorative surface in pedestrian precincts. For example, in the early 1900s, most of the streets in the city of Grand Rapids, Michigan were paved with brick. Today, there are only about 20 blocks of brick paved streets remaining (totalling less than 0.5 percent of all the streets in the city limits).
Bricks are also used in the metallurgy and glass industries for lining furnaces. They have various uses, especially refractory bricks such as silica, magnesia, chamotte and neutral (chromomagnesite) refractory bricks. This type of brick must have good thermal shock resistance, refractoriness under load, high melting point, and satisfactory porosity. There is a large refractory brick industry, especially in the United Kingdom, Japan and the United States.
In the United Kingdom, bricks have been used in construction for centuries. Until recently, almost all houses were built almost entirely from bricks. Although many houses in the UK are now built using a mixture of concrete blocks and other materials, many houses are skinned with a layer of bricks on the outside for aesthetic appeal.
Keeping Your ASP.NET Session Alive Using jQuery
When we are working with Asp.Net,We should take care about Session timeout.The time before timing out is normally configured in the web.config file. Sometimes sessions time out at the most inconvenient time for your users. They could start a page, fill in some data, go to lunch then come back, click next and one of two things happen. Either the user is redirected back to the starting screen,hat means the developer is not checking the session object for a null reference before using it.
One workaround for this is to keep the users session alive by running a small snippet of code which updates a session object.
First we create a Generic Handler.Below is the code for Generic Handler(i.e. SessionAlive.ashx)
public class SessionAlive : IHttpHandler, IRequiresSessionState
{
public void ProcessRequest(HttpContext context)
{
context.Session["KeepSessionAlive"] = DateTime.Now;
}
public bool IsReusable
{
get
{
return false;
}
}
}
public class KeepSessionAlive : IHttpHandler, IRequiresSessionState
If we didn’t inherit class from this interface, the ASP.NET Session wouldn’t be available and a null reference exception would be thrown. When you inherit a class from IHttpHandler, the main method that you use is ProcessRequest. All this method is doing is touching one ASP.NET session object simply to keep the session alive.
Now we write a javascript to call this SessionAlive.ashx code.For this we are using setInterval function.
Below is the Javascript Code
// <![CDATA[
javascript" type="text/javascript" src="http://code.jquery.com/jquery-latest.js">
// ]]>
<script language=”javascript” type=”text/javascript”>
$(function() {
setInterval(KeepSessionAlive, 10000); });
function KeepSessionAlive() { $.post(“/Shared/KeepSessionAlive.ashx”, null, function() {
$(“#result”).append(“<p>Session is alive and kicking!<p/>”); }); }
</script>
<h2>Will my session die?</h2> <div id=”result”></div>
setInterval(KeepSessionAlive, 10000); That function runs a jQuery post to the HttpHandler KeepSessionAlive.ashx:
$.post(“/Shared/KeepSessionAlive.ashx”, null, function() {
This means every 10 seconds the session will be updated behind the scenes. This will give the impression to the user that their session will not time out.

The DEMO-CAMP East/West, the first complex event for the IT-branch and the Internet start-up in Poznan.
On 22nd and 23rd October 2010 the DEMO-CAMP East/West, the first complex event for the IT-branch and the Internet start-up happening this year, will take place in Poznan.
The international event will gather Internet start-ups, venture capital, speakers and observers from all over Europe!
DEMOCAMP East/West 2010 stands for the already third edition of the fair for IT and start-up branches. The first edition of DEMOCAMP was held in 2008, and in May 2009 was followed with a more international focus. The great interest from start-ups and media was to be considered as an undoubted success, and that interest proved that there were many creative and unique ideas worth promoting and showing.
Encouraged by the success of previous editions, organizer the Polak 2.0 Foundation, decided to give it a go and continue the event, as it is the only one of its kind to be organized in Central Europe.
The whole event consists of modules like presentations of invited international speakers, the start-up exhibition, ‘unconference’ sessions and presentation stands as well as a discussion panel on co-investing with venture capital.
About 400 guests and participants as well as international competitors are expected to arrive and actively participate in this year DEMOCAMP edition.
There was an increase in the amount of initiatives aiming at the Internet start-ups this year, and DEMOCAMP will be something definitely outstanding!
The activities of the first day are going to be quite exciting, as the international Internet start-up competition will take place! Open to visitors, judged by experts, the competition allows each qualified team (15 this year) to present their ideas and to prove their concepts and business models in front of the public and jury, limited by 5 minutes only presentation time.
The first day also means the discussion panel for the venture capital on co-investing, that gives the companies and support institutions an opportunity to set up new business contacts.
The second day of the DEMOCAMP is marked by the ‘unconference’ session. The formula of ‘unconference’ prescribes that the division into observers and speakers is not natural any more. As the access to knowledge is widespread and easy, everyone with correspondending experience can share and discuss it with others. Numerous ‘unconference’ sessions will be simultaneously run by the participants of the event. An ‘unconference’ session means that every interested person can take the floor and share ideas, solutions and expectations. Recommended topics are those connected with setting up and developing a start-up company and Internet marketing.
So do not wait and join DEMOCAMP today! Become part of a great international event!
Organizer
DEMOCAMP is organized by the Polak 2.0 Foundation, which was established 2008 by a Polish company netguru ltd. As an experienced organizer of open meetings and Internet-related workshops, the Foundation can be proud of events like Barcamps in its home town of Poznan (more than 20 meetings and 2000 participants in total so far!) and 24-hour marathon for programmers Hackfest as well as 2 previous editions of DEMOCAMP that happened in only less than two years mostly helped by private donations. The Foundation is open to new experiences and ideas , and 2010 new events like ShopCamp for the Internet shops or FoodCamp for catering industry took place, and got a very positive feedback from its participants. It also recognizes the challenges that every NGO faces, and in September 2010 for the second time, it facilitated BridgeCamp to promote IT among non-governmental organizations.
DEMOCAMP will be held in Poznan, at Poznan International Fair grounds, from 22nd to 23rd October 2010.

Control Webcams With JavaScript (jQuery)
jQuery Webcam is a plugin which creates a transparent layer forcommunicating with a camera directly in JavaScript.
This plugin provides three different modes to access a webcam through a small API directly with JavaScript – or more precisely jQuery. Thus, it is possible to bring the image on a Canvas (callback mode), to store the image on the server (save mode) and to stream the live image of the Flash element on a Canvas (stream mode).
