I don't think so... I've seen similar issues in Visual Studio 2008 working on web projects where the build and rebuild would fail time after time. I knew that my changes shouldn't have affected the build so I just kept cleaning and building each of the individual projects in my solution until finally (and I do mean fin... |

If you're using SQL-Server then you should use a distributed transaction, since both MSMQ and SQL-Server support it. What happens is you wrap your database write in a TransactionScope block and call scope.Complete() only if it succeeds.

From my experience import/export is probably the way to go. Export creates a logical snapshot of your DB so you won't find it useful for big DBs or exacting performance requirements. However it works great for making snapshots and whatnot to use on a number of machines.

Delphi Out of resources |

Every project I compile with Delphi 7, in which I do ***not*** compile with run-time packages, gives a linker error: "Too many resources". Even a blank application gives this error.
In other words: Delphi died on me. |
Python has a pretty good IPC library: see <a href="http://docs.python.org/lib/ipc.html">http://docs.python.org/lib/ipc.html</a> |
A simple solution could be:
- Place the divergent classes outside of your normal classpath.
- Write a simple custom classloader and install it in main as your default.
- For all classes apart from the 5/6 ones the cassloader can defer to its parent (the normal system classloader)
- For the 5/6 ones (which... |
Unfortunately there is no tag in the standard JSP/JSTL libraries that I know of that would allow you to do this date calculation.

However, I'm not seeing why the right border isn't showing up.... |
With explicit cursors, you have complete control over how to access information in the database.

If you need to keep it "forever" probably the safest way is to print out the code and stick that in a plastic envelope to keep it safe from the elements.

Every form has "Opacity" property. Set it to 50% (or 0.5 from code) so will be half transparent. Remove borders and show it maximized before the form you want to have focus. You can change BackColor of the form or even set background image for different effects. |

- I would avoid putting in numeric OIDs and instead use 'OID names' and leave that hard work (of translating) to whatever SNMP API you are using.
If that is not possible, then it is okay to use OIDs as they should not change per the SNMP MIB guidelines. Unless the device itself changes but that requires a new MIB... |
I have played this game before. I don't necessarily think parallel processing is the way to go. You have shared objects in the game (levers, boxes, elevators, etc) that will need to be shared between processes, possibly with every delta, thereby reducing the effectiveness of the parallelism.

I'd recommend just creating an entirely separate model for this.
class Assignment(Model):
user = ForeignKey(User)
role = ForeignKey(Role)

This lets you do all the usual model stuff, such as

Just to point out; if this is a personal (home) server, as opposed to one in a corporate environment, then it's better not to bother hosting it - you won't necessarily have the bandwidth, and your ISP may not allow it.
As mentioned above, you will also need a static IP address, and you'll need to set up DNS records ... |

In my situation mocks work **really nice.** But I'm using Python, which is so dynamic that it makes many things involving testing much, much easier.

The best way is to run checks as you develop so you know where your pain points are.

D2009 uses UTF-16 for the default string type, although you can make variables UTF-8 if you need to.

String literals in DFMs have been UTF-8 since at least D7. Hence, there will be no increase in size due to strings in DFMs with D2009.

I personally like the [WWW::Mechanize][1] Perl module for these kinds of tasks. It gives you an object that is modeled after a typical web browser, (i.e. you can follow links, fill out forms, or use the "back button" by calling methods on it).

Drupal's include system should keep everything relatively lightweight as long as you only include what you need.

I tend to use setters when a value is write-only or there are multiple values to be set at once (obviously). Also my instinct, like yours, is to use getters and setters as a signal that a process may be long-running, spawn threads, or do some other non-trivial work. Also, if a setter has non-obvious prerequisites in th... |
Forget the Getter and Setter methods. Just use Properties.
An interesting thing to mention is that Properties are ending up as Setter and/or Getter method(s) in the assembly. Setter and/or Getter become a Property just by a little bit of metadata. So in fact, properties = setter/getter methods. |
