Hi All,

I have some issue with the OnDemand software installed in my machine. I am getting an issue with the OpenDoc functiobn which is used by the arsole.OCX file opening the document and writing the data in another file.

I am getting an error message no as "516".
And error message as FTDODWIN.dll could not be found.
Code used : lRet = m_oArs.OpenDoc(iDocCount, vbNullString, 0)

I assume there may be some dll installation missing in the installation process.

Please help me what will be the issue.

Thanks,

router protection from lightning

Posted: 18 Oct 2010 06:48 AM PDT

Can using wireless router give common mode surege protection?
i have a wireless router and like to know ways to protect router if a lighting strikes in the surrounding area. If i'm using the router wireless then there is no path between the computer and the router, so is it correct to say the over current which causes the router to burn will not flow and the router will be protected ?

Adobe Reader X expected within next 30 days

Posted: 18 Oct 2010 06:15 AM PDT

dobe Systems is expected to announce tomorrow the next version of its Acrobat software, dubbed Adobe Acrobat X.
The software will include the free PDF (portable document format) viewing software Adobe Reader X, which is expected to be available for download within 30 days, Adobe said.
The new version of Adobe Reader will feature sandboxing security technology designed to add an additional layer of protection against attacks targeting the popular PDF viewer. Adobe Reader Protected Mode will be enabled by default and included in Adobe Reader browser plug-ins for all the major browsers. The sandbox mechanism will keep PDF processing, such as JavaScript execution, 3D rendering, and image parsing, to a confined area and prevent applications from installing or deleting files, modifying system information, or accessing processes.



Microsoft uses sandboxing techniques in Office 2010 Protected View and Office 2007 and Google uses it in Chrome.


Adobe has more details about Adobe Reader Protected Mode. See here:

Father and Son send HD Camera in Space with iPhone: Homemade Spacecraft

Posted: 18 Oct 2010 06:10 AM PDT

Look at this video and read the description following it.



Video from a camera attached to a weather balloon that rose into the upper stratosphere and recorded the blackness of space. Seven-year-old Max Geissbuhler and his dad Luke Geissbuhler dreamed of visiting space. Armed with just a weather balloon, a video camera, and an iPhone, they basically did just that.

The father-and-son team from Brooklyn managed to send their homemade spacecraft up nearly 19 miles, high into the stratosphere, bringing back perhaps the most impressive amateur space footage ever. The duo housed the video camera, iPhone, and GPS equipment in a specially designed insulated casing, along with some hand-warmers and a note from Max requesting its safe return from whomever may find it after making it back to solid ground. All told, father and son spent eight months preparing for their homemade journey into space, in hopes of filming "the blackness beyond our earth."

Then, one day in August, Max, his father, and his friend Miles Horner headed out to a nearby park to see their dreams realized. After attaching their equipment to a 19-inch weather balloon and switching on the camera, they watched as their simple craft disappeared high into the sky.

"In August 2010, we set out to send a camera to space. The mission was to attach an HD video camera to a weather balloon and send it up into the upper stratosphere to film the blackness beyond our earth. Eventually, the balloon will grow from lack of atmospheric pressure, burst, and begin to fall.

"It would have to survive 100 mph winds, temperatures of 60 degrees below zero, speeds of over 150 mph, and the high risk of a water landing. To retrieve the craft, it would need to deploy a parachute, descend through the clouds and transmit a GPS coordinate to a cell phone tower. Then we have to find it.

"Needless to say, there are a lot of variables to overcome"

After a little over an hour, the craft reached the stratosphere, 100 thousand feet overhead, and captured some incredible footage of space before the balloon popped and fell back towards earth. They found their spacecraft 25 miles away from where they had let it go -- stuck up in a tree.

Although the camera's battery died some minutes before touching down, the footage the camera returned is impressive. And despite the fact that the craft didn't technically reach the boundaries of space, Max and his father are undoubtedly proud of their accomplishment.

Just as the space-race of the 1960s was driven by a spirit of exploration and ingenuity, so too was the bold idea of Max and Luke Geissbuhler to film the darkness beyond our planet with their homemade spacecraft. And just as mankind was at once emboldened by the success of science and the realm of possibility was widened for an entire generation -- perhaps this father-and-son team can inspire others to follow their dreams, too, do-it-yourself style.

Facebook applications leak users' private information

Posted: 18 Oct 2010 06:06 AM PDT

I just read this news from Times of India.



The Wall Street Journal is reporting that 10 popular Facebook applications have been transmitting users' personal identifying information to dozens of advertising and Internet tracking companies.

The newspaper said that the breach also includes users who set all their information to be completely private. And in some cases, it says, the apps provided access to friends' names.

A Facebook spokesman told the Journal that the company would introduce new technology to contain the breach. It's not clear how long the breach went on.

The paper says Facebook also has taken immediate action to disable all applications that violated their terms. Most apps are made by independent software companies, not by Facebook.

Click, call, save: Call2 launches Microsoft Outlook dialler

Posted: 18 Oct 2010 04:43 AM PDT

London, 18 October 2010 Call2 (http://www.call2.com) , a leading provider of high quality, low cost telephony, today announced the launch of its Microsoft Office Outlook dialler for Small and Medium sized businesses. Call2's Microsoft Office Outlook dialler enables smaller businesses, no matter where they are located in the world, to enjoy the most competitive rates on telephone calls that are normally reserved for larger corporations.

Call2's Outlook dialler is a free software plug-in that allows businesses to easily integrate the Call2 service into Microsoft Outlook. Call2's Outlook dialler let users:
· Save money on every call: up to 95% of the cost of calls to and from abroad
· Generate phone calls directly from Microsoft Outlook by simply clicking on a telephone number and dialling it

When a user generates a call through Call2, they are immediately called back and connected to the person they are calling. Because both calls are generated by Call2, users benefit from the incredibly low cost call rates that Call2 has negotiated.

Andrew Try, Managing Director of Call2 commented: "Call2 is aimed at any business form anywhere in the world which wishes to save money on its telephony services. Call2 is a new way to centrally buy and globally distribute high quality low cost telephony giving businesses all over the world the buying power to match the low cost telephony enjoyed by the biggest corporations. Call2 will save businesses money on every call that they make. With the new Microsoft Outlook dialler, it is even easier to generate calls from emails or contacts and start slashing phone bills."

"Every Call2 telephone call is delivered across traditional telephone lines, which means there is no reduction in call quality that is sometimes experienced with Voice over IP telephony," continued Try. "Essentially Call2 delivers the same high quality telephony service to small businesses at a vastly reduced cost."

Call2's Microsoft Outlook Dialler is available to download for free from Call2's website: http://www.call2.com

Why are team meetings such a waste of time?

Posted: 18 Oct 2010 01:07 AM PDT

In my own, personal, humble opinion; the best decisions aren't taken by a group rather, they are taken by individuals working alone. :rolleyes:

I had thousands of such occasions where I thought we were wasting everyone's time by calling them to a meeting to decide something very trivial.

I always wondered why team meetings are such a waste of time? Well, it could be your final year project meeting with your project mates or office-meeting with your boss - 99/100, it's a time-waste meeting.

What do you think? Do you agree? Tell me!

How Much Say Did Your Parents Have In Deciding Your Career?

Posted: 18 Oct 2010 01:02 AM PDT

I'm surprised when many engineering students (and even professionals) say that the decision of choosing engineering was actually taken by their parents. There are few examples of wannabe doctors turned engineers.

I'm sure there are many among us. What's your experience? Looking back, what do you think? Are you happy or not happy with it?

For me, it was my decision to take up engineering because as a kid I was fascinated with anything electric. Plus I saw my father fix almost everything on his own without needing help from anyone. That made an impression on my mind that 'Engineers can do anything!'.

It's a different story that I ended up becoming an entrepreneur related to computers & software. But that was my own decision too.

What say you?

PLL VCO Temperature Instability

Posted: 17 Oct 2010 11:27 PM PDT

I recently constructed a PLL synthesized weather band receiver. When I apply heat using a hair drier, the reference oscillator crystal remains on frequency. The VCO LO only remains on frequency for a short time until the VCO control voltage reaches its limit 7V, then the PLL drops out of lock.

Why does the VCO control voltage reach its limit so quickly at only 90 degrees F?
