So the problem I have is this - I need to store a Date for expiry where *only* the date part is required and I don't want any timezone conversion. So for example if I have an expiry set to "08 March 2008" I want that value to be returned to any client - no matter what their timezone is.
The problem with remoting it as a DateTime is that it gets stored/sent as "08 March 2008 00:00", which means for clients connecting from any timezone West of me it gets converted and therefore flipped to "07 March 2008"
Any suggestions for cleanly handling this scenario ? Obviously sending it as a string would work. anything else ?
thanks,

The "intelligent" routers live in the server room. As the company has grown, we've annexed additional space and not very elegantly run various lengths of CAT5 thru the ceilings etc. I've been finding various hubs and switches in the ceilings -- none of which is labeled or documented in any way.
Of course, das blinken-lights tell me that *someone* is connected to these devices, I just have no way of finding out *who*.
I can run traditional network map tools (there are tons of these things) and it shows me the IP-based things in the network. That's nice, but information I already have. What I need to know is the network topology -- how the switches (bridges) are interconnected etc.. And since they are off-the-shelf linksys unmanaged-types, they don't respond to SNMP so I can't use that...
What's the best/cheapest tool out there that I can use to analyze and detect things like hubs and switches in the network that don't respond to SNMP?
If there's no tool that you're aware of -- what generalized algorithm would you suggest to find this out? My guess would be that I could look at the ARP tables for the devices (switches, desktops, etc.) and build a chain that way, but I don't know if it's possible to get that from an unmanaged switch (let alone a hub).

I've been using jEdit for years, which is a uber-powerful text editor. It has syntax highlighting, but it doesn't have any language-specific features like code completion and intelligent refactoring. I'm finding that's hindering my productivity. I *desperately* want to like Eclipse. I really do. But I keep running into problem after problem.
1. Now that Eclipse can use an ant script to build, instead of just creating its own build environment from an ant script then ignoring any changes to it, I found some online guides and set it up. It doesn't seem ready for prime time, though. My ant script builds fine from the command line, but I get all these build errors because I need to tell Eclipse all this stuff the build.xml already has in it, like the CLASSPATH, and where external jars are.
2. When I leave Eclipse running for too long, or sometimes after my laptop wakes up from hibernate, the UI starts breaking. For instance, the tabs on the editor pane disappear, so I can only edit one file at a time, and it doesn't say which one it is.
3. We have faced several instances where classes weren't rebuilt that should have been, leading to inaccurate line numbers in debugging walkthroughs and other unpredictable behavior (this isn't just me; the two other developers trying it out with me are seeing the same thing).
4. I find it a huge hassle that the workspace is in a different place than my source code. I have other files I need to edit (xml files, etc), and for each directory I want to edit files in, I need to set up a special entry, and it doesn't even default to where my source code is when setting that up.
Do others face these same issues?
Are there better alternatives?

===
Our team is setting up nightly and continuous integration builds. We own Team Foundation Server and could use Team Foundation Build. I'm more familiar with CC.Net and lean that way but management sees all the money spent on TFS and wants to use it.
Some things I like better about CC.Net is the flexibility of notifications as well as the ease of implementing custom scripts.

I would like to replicate this behaviour for other (shorter) columns.

I can then serialize the Person using a DTO and send it down to the client. If the client changes the object, it can have an IsDirty flag on there so when it gets sent back to the server I know to update it.
But what if I have an Order object? This has the main header informaton, customer, supplier, required date, etc. Then it has OrderItems which is a List< OrderItem>, being the items to be ordered. I want to be able to use this business object on my UI. So I have some textboxes hooked up to the location, supplier, required date, etc and a grid hooked up to OrderItems. Since OrderItems is a List I can easily add and delete records to it. But how do I track this, especially the deleted items. I don't want the deleted items to be visible in my grid and I shouldn't be able to iterate over them if I used foreach, because they have been deleted. But I still need to track the fact there was a deletion. How do I track the changes. I think I need to use a unit of work? But then the code seems to become quite complex. So then I wonder why not simply use DataTables and get the change tracking for free? But then I read how business objects are the way to go.
I’ve found various examples on simple Person examples, bnut not header-detail examples like Orders.
BTW using C# 3.5 for this.

The system uses SQL Server 2000 as its database engine and I need to set up a system for refreshing the data in the training database with the data from the production database on a regular basis.
I want to use SSIS as we have SQL 2005 servers I can run the process from. I have a fair bit of SQL experience, but not much with SSIS. I have been trying to do this with the "Transfer Database Task" but haven't been having much luck, as it always throws an error.
If we ignore the use of configuration items etc and pretend all the database names and so forth are hard-coded, I have the following:
A Single SSIS "Transfer Database Task" with the following properties:
- Destination Overwrite: True
- Action: Copy
- Method: DatabaseOnline
The error I receive is:
> Error: The Execute method on the task returned error code 0x80131500 (ERROR : errorCode=-1073548784 description=Executing the query "EXEC dbo.sp_addrole @rolename = N'XXXXX' " failed with the following error: "The role 'XXXXX' already exists in the current database.".

The Execute method must succeed, and indicate the result using an "out" parameter.
I'm sure there is something obvious going on here, but surely if the task is set to overwrite the pre-existance of the role shouldn't matter? Does anyone know what I need to do to get this working?

Essentially I'm tasked with writing something that will cut down outbound spam on a zombified pc through a system of packet interception and evaluation. We have a number of algorithms we'll use on the captured messages, but it's the actual capture -- full on interception rather than just sniffing -- that has me a bit stumped.
The app is being designed for windows, so I can't use IP tables. I could use the winpcap libraries, but I don't want to reinvent the wheel if I don't have to. Ettercap seemed a good option, but a test run on vista using the unofficial binaries resulted in nothing but crashes.

1. Xdebug and Eclipse. Eclipse launches a web browser, but the browser tries to access a non-existent file in Eclipse's .app bundle.
2. Xdebug and NetBeans. It does a little bit better; a browser opens a page in /tmp which says "Launching. Please wait…" but nothing happens beyond that.
3. Xdebug and debugclient, the CLI tool which comes with Xdebug. MacPorts (which I used to install PHP and Xdebug) doesn't seem to install this by itself, and when I try compiling it by hand, I get told "you have strange libedit". Installing libedit via MacPorts doesn't solve that.
4. Zend's debugger (the precise name escapes me right now) and Eclipse. I can't recall what the problem was, as this was some time ago, but it didn't work.
With regards to Xdebug, at least, I'm fairly confident I've installed it correctly. It shows up with both a phpinfo() in a PHP file and a `php -i` in the CLI.
If anyone has managed to get PHP debugging working in some way or other on the Mac, I'd appreciate it if you could share with me how. Littering code with `var_dump($foo);die();` gets old quick. Bonus points if it can be done *without* using some bloatware editor like Eclipse, or that expensive proprietary thing Zend wants to sell me.

The "progressAnimation" is defined as a resource in the user control.
I tried adding the DataTriggers as a Style on the UserControl, but when I try to start the StoryBoard I get the following error:

cannot specify a TargetName. Remove TargetName 'progressWheel'.
ProgressWheel is the name of the object I'm trying to animate, so removing target name is obvisouly NOT what I want.
I was hoping to solve this in XAML using data binding techniques, in stead of having to expose events and start/stop the animation through code.

How best to capture that event? | I am working on a legacy project in VC++/Win32/MFC. Recently it became a requirement that the application work on a **tablet pc**, and this ushered in a host of new issues:
> 1. the software keyboard has to use a "toggle" mode for shift and control
> keys because the stylus cannot "press"
> control and "C" at the same time.
> 2. You cannot very easily keep a "keyboard focus" on a window when the
> stylus has to trail out of the focused
> window to push a key on the virtual
> keyboard.
I have been able to work with, and around these issues, **but am left with one wherein I could use some expert suggestions.**
I have a particular bug that is induced by the "lift" of the stylus off of the active surface. Basically the mouse cursor disappears and then reappears when you "press" it back onto the screen.
It makes sense that this is unaccounted for in the application. you can't "lift" the cursor on a desktop pc. So what I am looking for is a good overview on what happens (in terms of windows messages, etc.) when the lift occurs. Does this translate to just focus changes and mouseover events? My bug seems to also involve cursor changes (may not be lift related though). Certainly the unexpected "lift" is breaking the state of the application's tool processing.
**So the tangible questions are:**
1. What happens when a stylus "lift" occurs? A press?
2. What API calls can be used to detect this? Does it just translate into standard messages with flags/values set?
3. Whats a good way to test/emulate this when your development pc is a desktop? Am I just flying blind here? (I only have periodic access to a tablet pc)
4. What represents correct behavior or best practice for tablet stylus awareness?
Thanks for your consideration,

When I call the 'Execute' method on the service from a console application
all actions preformed run under the context of the 'Network Service' account.
The Network Service account has not enough rights to create an organization
so many problems occur during the action.
* Registry access not allowed.
* Not the correct SQL Server rights
* Not enough AD rights.
* ...
Impersonation doesn't work, the service uses the process account to perform
the actions. The only thing that works is to run the CRMAppPool identity as
an administrator which has the deployment administrator rights (added through
the Deployment manager tool).
But this issues in CRM deployment doesnt seem to faceoff from me :(. now that i have a new issue after changing the Pool identity to the system administrator, the deployment service gives an error saying Unauthorized!!!! and further when i check the log it says..

There two points of interest for the lifetime of this file. The first is when the data is being abstracted and the second is when the file is archived so that it can be shared.
When data is being abstracted, I've thought that renaming the file to something unique or append a unique string to filename to keep it from overwriting other existing files.
When the file is going to be archived, I've thought of three strategies. One is to keep all files uploaded from a certain data in one folder. (2006/sept/04, 2008/jan/05) The other is to keep a folder and keep filling it until some max number of files I want to keep in folder and then create another one (/folder001/, /folder002/, /folder003/, etc..). Another one is to create subfolders once they reach some threshold. So like (/j/jd/jde/jdelator) I've seen this in unix not sure how to explain this.

The colleagues in question have been tasked with providing some reports from an internal application with a large Oracle database backend, and they simply don't have the skills to do this. While some might questions whether I have those skills either (grin), apparently enough people think I do to mean I can't weasel out of it.
So to my question - in order to extract the reports from the database, my script is obviously having to connect and run queries. So far I've not managed to come up with a good solution for where to store the username / password for the database except as plaintext in the script.
Is there a good solution for this that someone else has already written, perhaps as a CPAN module? Or is there something else that's better to do - like keep the user / password combo in a completely seperate file that's hidden away somewhere else on the filesystem? Or should I be keeping them trivially encrypted to just avoid them being pulled out of my scripts with a system-wide grep?
Thanks in advance! | perl | bash | ksh | oracle | null | null | open | Best practises for holding passwords in shell / perl scripts?

This led me to think about the best way to group 'helper' functions together. The Java/C# way would be to use a class of static functions with a private constructor, e.g.:
class Helper
{
private:
Helper() { }
public:
static int HelperFunc1();
static int HelperFunc2();
};
However, being C++ you could also use a namespace:
namespace Helper
{
int HelperFunc1();
int HelperFunc2();
}
In most cases I think I would prefer the namespace approach but I wanted to know what the pros and cons of each approach are. If used the class approach for example, would there be any overheads? | c++ | class | namespaces | null | null | null | open | 'Helper' functions in C++
