Java Apache releasing new HttpComponents
http://hc.apache.org improved library and better code. bug fixes over earlier versions. but its a new set of packages so cannot port directly. but worth the time as its better than the earlier blokes. Quick Start Enjoy!
HttpComponents is used to make requests to a page web page as get/ post. site scraping etc. Contact us for a solution Sel2In

Low-Tech Fixes for High-Tech Problems
Dry Ink Cartridge
If your printer's ink cartridge runs dry near the end of an important print job, remove the cartridge and run a hair dryer on it for two to three minutes. Then place the cartridge back into the printer and try again while it is still warm.
"The heat from the hair dryer heats the thick ink, and helps it to flow through the tiny nozzles in the cartridge," says Alex Cox, a software engineer in Seattle. "When the cartridge is almost dead, those nozzles are often nearly clogged with dried ink, so helping the ink to flow will let more ink out of the nozzles." The hair dryer trick can squeeze a few more pages out of a cartridge after the printer declares it is empty.
Remote Car Key
Suppose your remote car door opener does not have the range to reach your car across the parking lot. Hold the metal key part of your key fob against your chin, then push the unlock button. The trick turns your head into an antenna, says Tim Pozar, a Silicon Valley radio engineer.
Mr. Pozar explains, "You are capacitively coupling the fob to your head. With all the fluids in your head it ends up being a nice conductor. Not a great one, but it works." Using your head can extend the key's wireless range by a few car lengths.
Credit Card wont swipe
...he reaches beneath the counter for a black plastic bag. He wraps one layer of the plastic around the card and swipes it again. Success. The sale is rung up. "I don't know how it works, it just does," says Mr. Azar, who learned the trick years ago from another clerk. Verifone, the company that makes the store's card reader, would not confirm or deny that the plastic bag trick works. But it's one of many low-tech fixes for high-tech failures that people without engineering degrees have discovered, often out of desperation, and shared.

Java HTTP Client 4 beta2
SOLUTION
TO :
cannot determine the required jar files to compile samples/ own files
example org.apache.http.examples.client.ClientFormLogin
used
set CLASSPATH=P:\j\samples\httpClient\examples;j:\j\j5\h;P:\j\e\mysql.jar;P:\j\e\commons-logging-api-1.1.1.jar;P:\j\e\commons-logging-1.1.1.jar;P:\j\e\4\httpmime-4.0-beta2.jar;P:\j\e\4\httpclient-4.0-beta2.jar;P:\j\e\4\h\e\4\httpcore-4.0-beta3.jar;P:\j\e\4\httpcore-nio-4.0-beta3.jar
but still needs org.apache.http.*; ... where are these jars? a quick start guide / link to all jars for one version would help
- only known workaround - go back to old version 3.1

Select Files & Folders: C# dotnet project excerpts
I recently had to do a MS Visual Studio DotNet C# project to mimic the back up tab of the Backup utility (attached image)
Two sites that helped : http://www.tangiblesoftwaresolutions.com/ and http://www.infragistics.com/ (tree view, over riding how a control is to be drawn, native support for 3 states of check boxes)
Interesting part is how it has to select parent nodes and gray them when you select a node whose parent/ grand parents are not selected.
Here is my altervative to using a image list and instead caching a few images

html javascript: change page title
To change the title of a document can use
<script type="text/javascript">
document.title = document.title + " :Run Mailer"; </script>
Useful when the title comes from a template but you want to customize
Ofcouse you dont have to append old title can just be
<script type="text/javascript">
document.title = "Run Mailer";
</script>
