how would a mobile phone control a PC?

think about it
if u have
xyz installed on ur pc
then it sends control messages to a web site and gets same from that website
on ur ohoine u justhave an app thats gets images, icon pos , click , type ...
from phone message goes to website
from website to the app on ur PC
where it is translated to native API
pretty simple
 
 
  personal computer/ desktop
  3rd party api on their app on ur pc  
 
   internet     3rd part web site    internet    mobile phone with app

MS Office excel VBA features

Instead of buttons: nice of a link could point to a macro. Click here to do this ... Can be dynamic create in scripts too.
 
Macro Security : keep a Code_Last_Modified_Date - if user trusts a code then a check box not to prompt to trust same file until code is modified.
 
Code Location: Keep code in a linked file - so can change classes etc via version control - in one go instead of having to go to the editor and pasting there. Anyway will be used by developers and when we distribute its our responsibility to tell the users to keep additional files in correct relative folders, or give an installer as with other programs.
 
Microsoft Office Macros are very powerful - and should be encouraged and new features added all the time.

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.
