  • Java Date vs Calendar

    - by Marty Pitt
    Could someone please advise the current "best practice" around Date and Calendar types. When writing new code, is it best to always favour Calendar over Date, or are there circumstances where Date is the more appropriate datatype?

  • What is your custom exception hierrarchy?

    - by bonefisher
    My question is: how would you create exception hierarchy in your application? Designing the architecture of an application, from my perspective, we could have three types of exceptions: the built-in (e.g.: InvalidOperationException) custom internal system faults (DB transaction failed on commit, DbTransactionFailedException) custom business exceptions (BusinessRuleViolationException) Class hierarchy: Exception MyAppInternalException DbTransactionFailedException MyServerTimeoutException ... MyAppBusinessRuleViolationException UsernameAlreadyExistsException ... where only MyAppInternalException & MyAppBusinessRuleViolationException would be catched.

  • Get script of SQL Server data

    - by Jared
    I'm looking for a way to do something analogous to the MySql dump from SQL Server. I need to be able to pick the tables and export the schema and the data (or I can export the schema via SQL Server Management Studio and export the data separately somehow). I need this data to be able to turn around and go back into SQL Server so it needs to maintain GUIDs/uniqueidentifiers and other column types. Does anyone know of a good tool for this?

  • How Ubuntu cloud version enforces the "no root login" over ssh ?

    - by Maxim Veksler
    Hello, I'm looking to tweak ubuntu cloud version default setup where is denies root login. Attempting to connect to such machine yields: maxim@maxim-desktop:~/workspace/integration/deployengine$ ssh [email protected] The authenticity of host 'ec2-204-236-252-95.compute-1.amazonaws.com (204.236.252.95)' can't be established. RSA key fingerprint is 3f:96:f4:b3:b9:4b:4f:21:5f:00:38:2a:bb:41:19:1a. Are you sure you want to continue connecting (yes/no)? yes Warning: Permanently added 'ec2-204-236-252-95.compute-1.amazonaws.com' (RSA) to the list of known hosts. Please login as the ubuntu user rather than root user. Connection to ec2-204-236-252-95.compute-1.amazonaws.com closed.

  • EloTouch touchscreen suspends correctly but does not come out of standby on Ubuntu 10.04

    - by Ton van den Heuvel
    I am using an EloTouch touchscreen on a minimal Ubuntu 10.04 installation. I have a bare Xserver running without any desktop environment, just an xterm. The touchscreen is working great, but there is still one small problem. As soon as the touchscreen goes to standby, it is not coming out of standby when touching the screen. Using a keyboard or mouse does get it out of standby though. I am looking for any hints or directions to a cause of this problem. Is this an x.org configuration problem? A driver problem? Is this a known problem with touchscreens in general? Any pointers are welcome. The driver I am using is an unreleased EloTouch driver (3.5.0). I received it through a reseller who can not give me any technical information unfortunately.

  • EnvDTE Retrieving the data type from a CodeElement

    - by chrischu
    I am using EnvDTE to generate some code in my latest project. I have a reference to a CodeClass-Object for a given C#-Class but now I wanted to loop through all of its members (in codeClass.Members) and check their types. However I can't manage to retrieve the type of the given member from the CodeElement-Object that I get when looping through codeClass.Members. How can I retrieve the type (int, string etc.)? PS: Reflection is not an option for my usecase.

  • Scala 2.8: _ behaviour changed?

    - by Alexey Romanov
    Using XScalaWT, this compiled under Scala 2.7: class NodeView(parent: Composite) extends Composite(parent) { var nodeName: Label = null this.contains( label( nodeName = _ ) ) } With 2.8.0 RC1, I get this error: type mismatch; found : main.scala.NodeView required: org.eclipse.swt.widgets.Label The types are: label(setups: (Label => Unit)*)(parent: Composite) : Label contains(setups: (W => Unit)*) : W So it looks like _ now binds to the outer function instead of inner. Is this change intentional?

  • Best approach for coding ?

    - by ahmed
    What should or how should I decide the best approach for coding as a smart programmer. I have just started programming last year in VB, and I keep on listening this statement. But I never could find by myself to choose the best approach for coding. When I search for a coding example on internet I find different types of approach to achieve the same target. So help me finding the best approach. (asp.net,vb.net)

  • SQL Server backward compatibility in Entity Framework?

    - by shake
    Is there any backward compatibility in the entity framework between SQL Server 2008 and 2005? It seems the framework forces you to use the same provider for all the .edmx files in a solution. If you use the 2008 provider, data types like DateTime2 and functions like SysDateTime that are emitted by the framework to the underlying SQL query make it useless to use them against a SQL 2005 Server. Any way around this?

  • Loading a Reusable UITableViewCell from a Nib

    - by Greg Martin
    I am able to design custom UITableViewCells and load them just fine using the technique described in the thread found at http://forums.macrumors.com/showthread.php?t=545061. However, using that method no longer allows you to init the cell with a reuseIdentifier which means you have to create whole new instances of each cell at every call. Has anyone figured out a good way to still cache particular cell types for reuses, but still be able to design them in Interface Builder?

  • Linq to object - Select Distinct

    - by Ben
    Hi, I can't quite figure out why this Linq Statement isn't working as i would expect: Dim distinctSurchargesList = (From thisparent As Parent In ThisParentCollection _ From thisChild As Child In thisparent.theseChildren _ Select New With {.childId = thischild.Id}).Distinct() I would assume that this would create a new collection of anonymous types, that would be distinct. Instead it creates a collection the size of the "ThisParentCollection" with duplicate "MyAnonymousType" in it (duplicate id's). Can anyone tell me where im going wrong? Thanks

Are there any common pattern, description of the system core which will events, making lists?

  • Polymorphism, Autoboxing, and Implicit Conversions

    - by dbyrne
    Would you consider autoboxing in Java to be a form of polymorphism? Put another way, do you think autoboxing extends the polymorphic capabilities of Java? What about implicit conversions in Scala? My opinion is that they are both examples of polymorphism. Both features allow values of different data types to be handled in a uniform manner. My colleague disagrees with me. Who is right?

  • Suspended Laptop Cannot Wake Up - Ubuntu

    - by Zack
    I've got an ASUS G73JH, and whenever I suspend it or hibernate it, it will not wake up. The screen stays backlight but is black. I can't: Awaken it with the keyboard Awaken it with the mouse Soft power-off by pressing the power button I have to hold down the power button and shut it down that way, and this seems a little unreasonable. Is there a place I could look for more detail as to what's causing this? Is there a known quick-fix to this issue?

  • Web-based interface is mangled

    - by justSteve
    Linksys WRT54 - over the last couple days i've been in and out of network configuration screens of my DSL modem and the router (and the commandline for that matter) as I've installed the DynDNS service. (thankx to subsonic and DynDNS.com i'm now able to stream my workstations MP3 catalog over my wife's Droid - making me her tech hero all over again) Somewhere after getting all the net ducks lined up - ports forwarded and firewalls configured - the web-interface for the router ceased rendering the full page - it's only rendering parts, i can F5/refresh and it re-renders and displays some of the cells (table-based webpage) but omits others that _had rendered before the refresh. Happens for both IE and FF. And continues after a reboot. Probably need to re-cycle the router itself but is this known behavior or should i look deeper for a cause? thx

  • Adobe Illustrator Saving to PSD: "Not enough memory to save the file"

    - by fiskfisk
    This is on CS5.5 under Windows XP Professional. There seems to be a known issue about saving (large) Adobe Illustrator files to PSD (thoroughly discussed), where the exporter will complain about "Not enough memory to save the file". This happens regardless of the available memory on the computer, and seems to be a limitation in the PSD exporter itself. The only possible solution so far seems to be to copy-n-paste each layer separately from the illustrator file and into the open Photoshop file. We need to keep the layers intact (and not merged), so selecting all the layers at the same time doesn't work. Do anyone have a workaround to the actual, original export issue, or a way to be able to get the layer information into Photoshop without handling each layer separately?

  • Javascript Chart to Excel

    - by George
    Hi I'm using highcharts to create some charts (pie, bar, etc...) using just Javascript. These charts do not use Flash or anything like that. Is it possible for me to convert the resulting HTML page with the Javascript chart to an excel document that properly shows the image? I've tried the standard change mime types for excel and so far I've only been able to export an HTML table on the page, but no chart.

  • SQL Server iSCSI session issue with a NetApp SAN

    - by Matt Beckman
    We had an issue early this morning when iSCSI issues broke connectivity with a few of our databases (resulting in a SQL Server Error 21). Attempts to DBCC CheckDB did not work, and the only solution was to restart the SQL Service. Is there a known reason why an iSCSI initiator session would reset itself out of the blue? Example below from the NetApp syslog. This set of errors was replicated 4 times (once for each SQL server in production). Only one SQL server was noticeably impacted, however. [san1: iscsi.notice:notice]: ISCSI: iswta, ISID Rule: new connection from same initiator, shutting down old session 7 [san1: iscsi.notice:notice]: ISCSI: iswta, New session from initiator iqn.1991-05.com.microsoft:sql1.example.corp at IP addr 10.xxx.xxx.123
