Get Stock Quotes on the Web with SSL Sockets for .NET

This sample demonstrates how easy it is to get files or data from an Internet resource in ASP.NET with the PowerTCP SSL Sockets for .NET. This sample connects to "finance.yahoo.com" on port 80 (the well-known port for HTTP). An HTTP GET request is then sent for the Yahoo Stock Quote Display Page, specifying the stock quote to get as a query string parameter in the url. This causes the Yahoo server to return an HTML formatted page containing the information for the stock quote, including the current price. The current price is then parsed from the response and displayed. Other information is parsed from the page as well, such as the name of the company, and the percentage change.

... just finished an automated ftp process with PowerTCP and Visual Basic 4 ... works great!!! Thanks for a great product
-- Pat Todd, Cycon Publishing, Inc.

...we are very impressed with your .NET RapidSpell product...
-- J.D.L., Monster.com

Again thank you! I have been in this business a long time, and have very rarely come across your level of professionalism and responsiveness. With each interaction I am more confident in my decision to use your product. Thought you might like to know, this isn't being used in any small scale application. It is for a Fortune 50 company, with thousands of users. So far they love this new feature!
-- A.A., Concurrent Technologies

Because we have several hundred users of PowerVT in our large facility, being able to configure the system once and put it on the file server for distribution was a life saver!

Bottom line, coding and deployment went like a charm. User is happy, my boss is happy, I am happy.
-- Geoff Sutcliffe, Datagaard Pty Ltd

Dart's PowerTCP FTP for .NET does everything we need it to and does it very well at that. One thing I see with a lot of .NET products, but NOT yours, is poor documentation... Dart has always done this right.
-- Eric Zimmerman

Dart's PowerTCP SNMP Tool really meets our needs for our project of making managed network gear. We tried another company's product, but it fell short of meeting our needs. As a programmer, I am really impressed with Dart's SNMP Tool. With the PowerTCP SNMP Tool, in minimal time, I was able to create a full-blown Visual manager that shows our network cards visually in a rack on the screen in real time. With full trap support to boot. Great work on Dart's part!
-- M. Aarons

Dart's PowerTCP Tools are excellent and the staff is very professional. Dart's Web Enterprise Tool is great; it took me just one day to learn this component and add it in my application. PowerTCP is perfect!
-- J. Duchemin

Dart's PowerTCP WebServer Tool is brilliant! In only two days, I was able to build a finished application for controlling lights in large buildings.
-- S.Sidwell

Easy to integrate, nice interfaces, very speedy even with a medical dictionary. We evaluated several spell checking engines and chose Keyoti; It was a good decision. Works well, easy to integrate.
-- Tim Bassett, CHCSII

Having tried several TCP toolkits and even writing our own components in Delphi against the Winsock DLL, we found the PowerTCP kit to be far superior to any other method of implementing TCP/IP communications. The ease of installation, clean straightforward properties and methods made conversion a quick and painless procedure. PowerTCP is at the top of a long list of 3rd party tools and components we use, a position it earned and deserves.
-- Ed Purkiss, W. D. Macodi Corporation

I am truly happy that we purchased this product. I have seen no other package that provides the level of professionalism and support of Dart's PowerTCP. You guys are great. This is by far the best support response I have encountered in my development career ... Anyway, thanks once again for the fast response. We currently have 4 development kits of PowerTCP and I would highly recommend your product over any other. Keep up the good work.
-- Layne Grantham , Coca-Cola Enterprise

I am using Dart's PowerTCP FTP Tool in developing a software program to do automatic upgrades of our website. Compared to other commercial products I have seen on the market, PowerTCP is the best!
-- S. Normand

I am very happy with Dart's PowerTCP Tools. I have used the Web Tool for web scraping applications and for retrieving XML documents. It has worked flawlessly!
-- F. Biondo

I am very happy with my purchase. Your product has saved me much time and aggravation.
-- Duane Kiser, JS Express Inc.

I don't know how to thank you for the help you provided regarding my FTP server question. I looked at what you sent me and things just started to fall into place. I was able to get the server working on an NT machine using VB5.
-- Mike, Warner Lambert

I have been in the computing industry for 20 years, and this is the best customer relation response that I have ever experienced with the exception of the former Digital. If your company has a stock offering someday, please let me know, I am interested in investing ...
-- Gene Hirschel, Chase, STO

I just wanted to extend my thanks for all the assistance you have provided me and my company in straightening out our software version issues and quickly processing our purchase order for the Telnet licensing. I regularly deal with a large number of customer and vendor issues and understand the problems that urgent requests like ours can incur. As such, I felt it necessary to let you know that your efforts did not go unappreciated. Thank you.
-- Marc Alan Asher , National Systems Corporation

I recently bought the PowerTCP Emulation Tool from your company and integrated it into my [Delphi] application. It does a GREAT job for me and is just what I needed to implement a custom terminal emulator in my application!
-- Phillip H. Blanton, Sprint Corporate Security, LAN Systems

I think Dart's PowerTCP Tools are wonderful! PowerTCP works like a champ. I am using the PowerTCP FTP Tool for a current project and I love it!
-- G. Veduccio

I think the PowerTCP Server Tool is absolutely fantastic! I wished for someone to develop a component that would take care of multithreading incoming connections so I could just write the logic, and then I found Dart’s PowerTCP Server Tool.
-- C. Davies

I think you have a GREAT product. I have bought others that cost more and could not even get them to work.
-- L.R., Nashville Government

I used the FTP control ... and was able to add the functionality needed by my application within a single afternoon. It was very easy to use and the code worked the first time I tested it. It was a godsend because I spent 3 days trying to get the Internet Transfer Control (that comes with Microsoft Visual Basic Version 5) to work and couldn't.
-- Chris, Xerox Corporation

I was very pleased by the way your Telnet tool works. The documentation and example applications are head and shoulders above the competition.
-- Richard Anderson, Canyon Software

It's a great tool. It's so well designed and written that I don't think I'll ever need any technical support. I've written several small apps with it already.
-- Neil McAliece

Just like to say that you have created the best ever set of controls with the PowerWeb LiveControls. Absolutely amazing !!!
-- Martin Oliver Madsen

Just to tell you that your WebServer product is just wonderful. Thanks to it I am now smiling when I develop web applications...My wife is happy too!
-- Christian Nicaud

Modelled completely on MS Word's spell checking capability, this component is thorough in its offering and easy to implement. This looks, feels, and works exactly like MS Word's spell checker. It even supports multiple languages. Nice, well thought out component.
-- William Lucking, Orange Rocket

Not only did I receive a quick response to my PowerVT support issue, but the fix was right on - very impressive! I was able to finish my financial reporting on time for the med center.

Not only was PowerVT among the best products tested, it also proved extremely economical and the support offered by staff at Dart Communications has been first rate. So satisfied have I been with the service provided that I have no hesitation in recommending this product to others.
-- Duncan Burr, Lion Publishing

Overall an excellent product. By using the SNMP tools, we have been able to implement an SNMP capability into our Network Management System at a fraction of the cost of using an SNMP 'expert' such as HP OV.
-- Andrew Williams, Network Management Systems

PowerTCP is a great product. From day one of installing the software I had TCP/IP and FTP demos ready the same day. Your package makes it very easy doing either synchronous or asynchronous communication. I've tried other products and they just don't have what it takes for rapid development and reliability. It literally only took about 10 minutes for me to start passing and receiving packets over the Internet. I've been using VB for the past three years and this product is definitely on my top 5 of third party controls.
-- Ryan Ragle, Walsh Distribution

PowerVT allows us to print critical information directly from the PC - significantly reducing the time spent printing patient reports and reporting pharmacy orders.

PowerVT's multiple window feature has proven very helpful in the IT department, as it allows multiple SQL sessions to be set up when compiling reports. It will also be useful when the new finance system is in operation, as wards will be able to have patient and inventory open simultaneously, without running multiple instances of a program.

So far, it [ PowerTCP ] has far surpassed our expectations! We needed to change the default keycode sequences in the VT client, and you included that information right on the front page of the product! VERY IMPRESSIVE! Thanks for such a great product!
-- Robert May, Direct Communications

SOESoft relies entirely on the Dart PowerTCP range of ActiveX controls for all our network related functions for our product suite. By exhaustive research SOESoft has proven beyond a doubt that Dart controls are the most robust, reliable and industrial strength controls on the market. Due to the nature of our products second best is not an option. Additionally, SOESoft contracted Dart to produce a custom control for us. This was a great experience for us with the control developed to the best standards and on time. SOESoft sincerely thank Dart for their professionalism and quality of product.
-- Simon Manners, Product Development Manager, SOESoft Pty Ltd

Thank you for your quick response again. You really did a very good job to support us. I just want to tell you my appreciation.
-- Jack Chiang , Lucent Technologies

Thank you VERY MUCH for your immediate response. This relays a very positive impression about Dart Communications. Your responsibilites to communicate with your customers is very reassuring. The same goes for support@dart.com, too.
-- Michael Beer

Thanks for the quick response and the great service.
-- Jim Baron, Logica

The combination of PowerTCP FTP for .NET and the .NET Framework will provide an easy-to-use solution to meet the needs of our mutual customers.
-- John Montgomery, Microsoft Group Product Manager

The most stable and reliable product I have ever worked with and it is very easy too. It is part of a program made in PowerBuilder handling requests from a voice response system; this program has been running for the last 5 months without being restarted once. It handles 2-5 thousand calls per day. Great product!
-- Thomas Ulrich

The PowerTCP FTP Tool that we purchased from Dart is excellent! It did everything we asked of it. We met our goal using it. We were able to successfully navigate various firewall configurations at our client sites and get them all using FTP to access our proprietary data. I evaluated several other FTP controls and utilities and none of them provided the same flexibility that Dart’s FTP control did!
-- J.Fade

The PowerTCP Mail Tool and FTP Tool are excellent. They are both feature rich and robust and the technical usage documentation is helpful. I love both products.
-- J. Palmer

The PowerTCP Zip Tool enabled me to encrypt data and send it over the Internet without creating a physical file on the server ! I did this using the native stream capability. This enables a client to ask for data from the server, have the data compressed into a zip file on the server, and then sent to the client without any extra files being created on the server. Furthermore, the FileStore concept allows me to store multiple files in a single compressed file, allowing for a really clean client/server distribution model. Other controls let me compress, encrypt, etc., but your design allows for a clean delivery mechanism, which is not easily accomplished with other products.
-- JR, Developer, Sunnyvale, CA

This is the best FTP product I've seen yet!
-- Steve Jantzi

Until now I've used the zlib control. After encountering problems with it, I was happy to find your control was as easy to use (if not easier), had much more functionality and a very good help file.
-- Philip Jeary

Using PowerTCP makes a great pleasure to me. When I received the copy, I could include immediately the TCP/IP connection into my application using your tools. It works very well.
-- Dietmar Käppeli, Miratec AG

Using PowerVT via Telnet allows physicians to connect to critical mainframe data through their laptops while off-site - a necessity for doctors in our facility.

We are extremely happy with the product. It works well, which is the highest praise we can give a product.
-- Frank Carey, W. J. Schafer Associates

We are using Dart's PowerTCP FTP Tool in a product developed for the medical industry. The FTP Tool is used to download files from a website. PowerTCP solved my problems and did the job admirably.
-- C. Martin

We have a few other toolkits that we’re working with in-house. Of all, I personally, have found PowerTCP to be most useful.
-- Gabriel Perez, NetSolve

We know that the reputation of our product depends on the quality of the components we OEM. Dart's professional approach to its products and its customers has resulted in trouble-free integration of some great technology and a great OEM relationship.
-- Juan Guillen, Simware Inc

We tried repeatedly to use Microsoft Windows' built-in FTP features in our applications, but found that they were not reliable or stable enough to meet the needs of our end-users. Dart's ActiveX FTP component fit the bill perfectly -- bulletproof and easy to deploy. Additionally, we found the staff at Dart to be very responsive, knowledgeable and professional. In the future, we'll look to Dart first for our development component needs, especially as we move toward the .Net environment.
-- Jim Erwin, President and CEO of Synapse Software, Inc

We’re using the PowerTCP Mail Tool in an application we’re currently developing to do an application ‘auto-update’. Dart’s PowerTCP tools work perfectly.
-- A. Powell

Well, am I impressed with this stuff of yours. Calls up the dial up network connection and just goes right to it. Please tell whoever is coding down there that they have one impressed puppy up here in Canada. It took me 30 days to install the Distinct software and only a few hours to put in your code.
-- Glenn Brand

What can I say....I am sold, I have developed my own set of TCP Tools, and am going to back them out in favor of Dart Tools! This stuff is fantastic! I have worked with a number of toolkits over the years and this Secure TCP is one of the best yet.
-- Janet Broadway, Jan-Net Technical

You have been very good communicating with us (which I still find to be a rarity) for net based businesses, that is why I will not wish you good luck as Luck as a commodity you do not need when you exhibit such a degree of professionalism as your company does.
-- Jase H. Przychodzen, EDS, Australia at Adelaide Institute of TAFE

You have no idea how much easier your product (PowerTCP) has made my current project. P.S. I love this product
-- Daron Lord, Arizona Superior Court in Pima County

Your FTP component, which I'm using in an important project, is very robust and flexible, and the documentation is probably the clearest and most thorough I have encountered in ANY software product. Everything shows the highest level of professionalism and forethought!
-- Michael Nachison, Horizon Real-Time Systems

Your FTP Tool was powerful and intuitive. I really liked the consistent and logical structuring of the control. Also, I was impressed with your attention to customer service. I will definitely look to Dart for my future project needs.
-- J. Iverson

I love these Controls! They've allowed me to create a web-application that I couldn't even dream of doing without them...my boss now thinks I'm a genius!
-- Clive Jenkins
