This is what Procmail is for.
Set Sendmail up to use procmail as the mail delivery agent (MDA), or set up your .forward to pipe stuff through procmail. (See the man page.)
Then you can write your .procmailrc to do all sorts of things along these lines.
This filter predates gmail. Still useful if you're running... |

[There is a .NET version of QuickReports supported in Delphi 2005 and Delphi 2006][1]. You have to get the (non-free) "professional" version of QuickReports to get the .NET support, however.

For a long time I didn't understand pointers, but I understood array addressing. So I'd usually put together some storage area for objects in an array, and then use an index to that array as the 'pointer' concept.

SomeObject A = store[a_ptr];

It really depends on the specific JVM implementation. I assume you're wondering about Sun's Windows JVM, and I can tell you with certainty that the Sun JVM maps a Java thread to an OS thread.

I would say keep it as simple as possible. Internet on phones can be 3g/wifi or as slow as you can possibly imagine. I would keep the test large so it's easier to read, and links easy to click if you are targeting a touch device. I would also say no to images unless they are 1kb or less. |
