  • SQL SERVER Create Primary Key with Specific Name when Creating Table

    It is interesting how sometimes the documentation of simple concepts is not available online. I had received email from one of the reader where he has asked how to create Primary key with a specific name when creating the table itself. He said, he knows the method where he can create the table and then [...]...Did you know that DotNetSlackers also publishes .net articles written by top known .net Authors?

  • Computer Engineer in CS Interview

    - by blasteye
    As a Computer Engineering student, while in school I've primarily dealt with C, Matlab, and VHDL. On my own though, i learned a bit about OOP (Polymorphism, inheritance, encapsulation), and have done quite a bit of web development using JavaScript/PHP/Node.js While at coding interviews I've be asked academia CS questions such as "abstract vs interface". The problem is that I didn't know the official terminology, but I have dealt with this type of programming decisions/concepts. Could anyone recommend a good resource for me to learn these academia CS terms?

  • What are the advantages and Disadvantages of Using an Aspect Orientated Programming Paradigm

    - by JHarley1
    Ok so here is the question: What are the advantages and Disadvantages of Using an Aspect Orientated Programming Paradigm. My advantages and disadvantages thus far: Advantages: Complements object orientation. Modularizes cross-cutting concerns improving code maintainability and understandability. Disadvantage: Not the easiest of concepts to grasp - not as well documented as O-O O-O goes far enough in the separation of concerns... List item Would anyone like to challenge any of these/ add their own? Many Thanks, J

  • Débats autour de la branche 4.x d'Eclipse, la fondation Eclipse est elle en train de rater sa migration ?

    Depuis plusieurs années deux versions majeures d'Eclipse existent: la branche 3.x (historique) et la branche 4.x (précédemment baptisée e4, reposant sur de nombreux nouveaux concepts). En 2012, deux versions ont été publiées: la fondation Eclipse sort Eclipse Juno 3.8 /4.2. Dans la pratique, la version 4.2 est la version officielle, celle qui est mise en avant. Les versions packagées d'Eclipse (EPP builds) proposées sur la page des téléchargements reposent sur la version 4.2. Pourtant cette migration ...

  • TechEd 2014 Day 3

    - by John Paul Cook
    There is some confusion about durability of data stored in SQL Server in-memory tables, so some review of the concepts is appropriate. The in-memory option is enabled at the database level. Enabling it at the database level only gives you the option to specify the in-memory feature on a table by table basis. No existing tables or new tables will by default become in-memory tables when you enable the feature at the database level. If you choose to make a table an in-memory table, by default it is...(read more)

  • Are there any good Java/JVM libraries for my Expression Tree architecture?

    - by Snuggy
    My team and I are developing an enterprise-level application and I have devised an architecture for it that's best described as an "Expression Tree". The basic idea is that the leaf nodes of the tree are very simple expressions (perhaps simple values or strings). Nodes closer to the trunk will get more and more complex, taking the simpler nodes as their inputs and returning more complex results for their parents. Looking at it the other way, the application performs some task, and for this it creates a root expression. The root expression divides its input into smaller units and creates child expressions, which when evaluated it can use to build it's own result. The subdividing process continues until the simplest leaf nodes. There are two very important aspects of this architecture: It must be possible to manipulate nodes of the tree after it is built. The nodes may be given new input values to work with and any change in result for that node needs to be propagated back up the tree to the root node. The application must make best use of available processors and ultimately be scalable to other computers in a grid or in the cloud. Nodes in the tree will often be updating concurrently and notifying other interested nodes in the tree when they get a new value. Unfortunately, I'm not at liberty to discuss my actual application, but to aid understanding a little bit, you might imagine a kind of spreadsheet application being implemented with a similar architecture, where changes to cells in the table are propagated all over the place to other cells that need the result. The spreadsheet could get so massive that applying multi-core multi-computer distributed system to solve it would be of benefit. I've got my prototype "Expression Engine" working nicely on a single multi-core PC but I've started to run into a few concurrency issues (as expected because I haven't been taking too much care so far) so it's now time to start thinking about migrating the Engine to a more robust library, and that leads to a number of related questions: Is there any precedent for my "Expression Tree" architecture that I could research? What programming concepts should I consider. I realise this approach has many similarities to a functional programming style, and I'm already aware of the concepts of using futures and actors. Are there any others? Are there any languages or libraries that I should study? This question is inspired by my accidental discovery of Scala and the Akka library (which has good support for Actors, Futures, Distributed workloads etc.) and I'm wondering if there is anything else I should be looking at as well?

  • Help with understanding why UAC dialog pops up on Win7 for our application

    - by Tim
    We have a C++ unmanaged application that appears to cause a UAC prompt. It seems to happen on Win7 and NOT on Vista Unfortunately the UAC dlg is system modal so I can't attach a debugger to check in the code where it is, and running under msdev (we're using 2008) runs in elevated mode. We put a message box at the start of our program/winmain but it doesn't even get that far, so apparently this is in the startup code. What can cause a UAC notification so early and what other things can I do to track down the cause? EDIT Apparently the manifest is an important issue here, but it seems not to be helping me - or perhaps I am not configuring the manifest file correctly. Can someone provide a sample manifest? Also, does the linker/UAC magic figure out that the program "might" write to the registry and set its UAC requirements based on that? There are code paths that might trigger UAC, but we are not even at that point when the UAC dlg comes up. An additional oddity is that this does not seem to happen on Vista with UAC turned on. Here is a manifest (that I think is/was generated automatically): <?xml version='1.0' encoding='UTF-8' standalone='yes'?> <assembly xmlns='urn:schemas-microsoft-com:asm.v1' manifestVersion='1.0'> <trustInfo xmlns="urn:schemas-microsoft-com:asm.v3"> <security> <requestedPrivileges> <requestedExecutionLevel level='asInvoker' uiAccess='false' /> </requestedPrivileges> </security> </trustInfo> <dependency> <dependentAssembly> <assemblyIdentity type='win32' name='Microsoft.Windows.Common-Controls' version='6.0.0.0' processorArchitecture='*' publicKeyToken='6595b64144ccf1df' language='*' /> </dependentAssembly> </dependency> <dependency> <dependentAssembly> <assemblyIdentity type='win32' name='Microsoft.Windows.Common-Controls' version='6.0.0.0' processorArchitecture='x86' publicKeyToken='6595b64144ccf1df' language='*' /> </dependentAssembly> </dependency> </assembly> And then this one was added to the manifest list to see if it would help <?xml version="1.0" encoding="UTF-8" standalone="yes"?> <assembly xmlns="urn:schemas-microsoft-com:asm.v1" manifestVersion="1.0"> <assemblyIdentity version="1.0.0.0" processorArchitecture="x86" name="[removed for anonymity]" type="win32" /> <description> [removed for anonymity] </description> <dependency> <dependentAssembly> <assemblyIdentity type="win32" name="Microsoft.Windows.Common-Controls" version="6.0.0.0" processorArchitecture="x86" publicKeyToken="6595b64144ccf1df" language="*" /> </dependentAssembly> </dependency> <trustInfo xmlns="urn:schemas-microsoft-com:asm.v2"> <security> <requestedPrivileges> <requestedExecutionLevel level="asInvoker" uiAccess="false"/> </requestedPrivileges> </security> </trustInfo> </assembly> The following is from the actual EXE using the ManifestViewer tool - <assembly xmlns="urn:schemas-microsoft-com:asm.v1" manifestVersion="1.0"> <assemblyIdentity version="1.0.0.0" processorArchitecture="x86" name="[removed]" type="win32" /> <description>[removed]</description> - <dependency> - <dependentAssembly> <assemblyIdentity type="win32" name="Microsoft.Windows.Common-Controls" version="6.0.0.0" processorArchitecture="x86" publicKeyToken="6595b64144ccf1df" language="*" /> </dependentAssembly> </dependency> - <dependency> - <dependentAssembly> <assemblyIdentity type="win32" name="Microsoft.Windows.Common-Controls" version="6.0.0.0" processorArchitecture="*" publicKeyToken="6595b64144ccf1df" language="*" /> </dependentAssembly> </dependency> - <trustInfo xmlns="urn:schemas-microsoft-com:asm.v2"> - <security> - <requestedPrivileges> <requestedExecutionLevel level="asInvoker" uiAccess="false" /> </requestedPrivileges> </security> </trustInfo> </assembly> It appears that it might be due to the xp compatibility setting on our app. I'll have to test that. (we set that in the installer I found out because some sound drivers don't work correctly on win7)

  • Concept of bit fields

    - by user1369975
    Whenever I read a code like this: struct node { int x : 2; int p : 4; }n; with bit fields involved, I get really confused, as to how they are represented in memory, what is sizeof(n) etc., how does it differ with normal members of structures? I tried referring K&R and http://en.wikipedia.org/wiki/Bit_field but they little to remove my confusion. What concepts of bit fields am I failing to grasp?
