• Is there a standard dialog for constructing an ADO.Net connection string (that is redistributable)?

  - by rathkopf

  I want to use a standard dialog to solicit user input of an ADO.net connection string. It is trivial to do for the oledb connection string as described here: MSDN Article on MSDASC.DataLinks().Prompt I've also found examples that use Microsoft.Data.ConnectionUI.dll and MicrosoftData.ConnectionUI.Dialog.dll from VS (HOWTO: Using the Choose Data Source dialog of Visual Studio 2005 from your own code). Unfortunately these DLLs are not licensed for redistribution. Is there a standard dialog for choosing a data source that can be distributed with my application?

• JavaScript/JSON Serializer

  - by Water Cooler v2

  I see that a JSON serializer is present in the System.Web.Script.Serialization namespace, and is shipped in the System.Web.Extensions.dll assembly. Is this assembly distributed with the .NET framework v4.0 redistributable? Is it also guaranteed to be present on a user's machine if any edition of Visual Studio 2010 is installed?

• Can I cache a ManyToOne hibernate object without it being lazy loaded?

  - by Andrew

  @ManyToOne @JoinColumn(name = "play_template_id", table = "team_play_mapping" ) public Play getPlay() { return play; } public void setPlay( Play play ) { this.play = play; } By default, this is eager loading. Can I get it so that it will read the play object from a cache without making it lazy loading? Am I correct that eager loading will force it to do a join query and hence no caching?

• How to choose between UUIDs, autoincrement/sequence keys and sequence tables for database primary keys?

  - by Tim

  I'm looking at the pros and cons of these three primary methods of coming up with primary keys for database rows. So assuming I am using a database that supports more than one of these methods, is there a simple heuristic to determine what the best option would be for me? How do considerations such a distributed/multiple masters, performance requirements, ORM use, security and testing have on the choice? Any unexpected drawbacks that one might run into?

• Accessing Erlang business layer via REST

  - by Polyn

  For a college project i'm thinking of implementing the business layer in Erlang and then accessing it via multiple front-ends using REST. I would like to avail of OTP features like distributed applications, etc. My question is how do I expose gen_server calls/casts to other applications? Obviously I could make RPC calls via language specific "bridges" like OTP.net or JInterface, but I want a consistent way to access it like REST.

• Working with the IE cache from C# & WPF

  - by Eric

  I'm writing a program in C# using the WPF framework. I need to display images, and I'd like to cache them to avoid downloading them constantly. I can code my own cache, however, IE already has a caching system. I can find code to read entries out of the IE cache, however I've found nothing dealing with the issue of adding items to the cache. Is there a good way to do it, or should I just implement a separate cache?

• Mercurial Workflow for small team

  - by Tarski

  I'm working in a team of 3 developers and we have recently switched from CVS to Mercurial. We are using Mercurial by having local repositories on each of our workstations and pulling/pushing to a development server. I'm not sure this is the best workflow, as it is easy to forget to Push after a Commit, and 3 way merge conflicts can cause a real headache. Is there a better workflow we could use, as I think the complexity of distributed VC is outweighing the benefits at the moment. Thanks

• How to get a list of the latest revision number for each file in a Mercurial repository?

  - by Kimble

  I have made a build system for my web application that's rewriting all resource url's to include the file's revision number (to improve client caching). As of today I'm running this command for each file to get the revision number: hg log --template '{rev}\n' path-to-file Executing hg for each file is really time consuming. Is there a fast way to list all files in a repository with the latest revision number?

• How and/or Why is Merging in GIT Better than in SVN?

  - by John

  I've heard a few places that one of the main ways distributed version control systems shine, is much better merging than traditional tools like SVN. Is this actually due to inherent differences in how the two systems work, or do specific DVCS implementations like GIT/Mercurial just have cleverer merging algorithms than SVN?

• LInux C++: how do profile time wasted due to cache misses?

  - by anon

  I know that I can use gprof to benchmark my code. However, I have this problem -- I have a smart pointer that has an extra level of indirection (think of it as a proxy object). As a result, I have this extra layer that effects pretty much all functions, and screws with caching. Is there a way to measure the time my CPU wastes due to cache misses? Thanks!

• C++ application as a service with high performance

  - by sand

  I need to provide a C++ application as a service. Client of the service and the service can be on the same machine or distributed on different machines based on the load. This application takes a ~2KB string as input and returns almost similar size of string after some processing. Turnaround time for the client should be really quick. What is the best mechanism to implement this?

• What binary architectures should be cross-compiled when building Mac OS X packages?

  - by Alex Leach

  Currently, Apple's native binaries and libraries are distributed as fat files, with support for both i386 and x86_64 architectures. The SDK (Xcode 4.4 w/ command line tools) doesn't support cross-compiling powerpc binaries any more, so they can be safely ignored I think, but there doesn't seem to be any specific guidelines or recommendations about which Intel architectures to support. So, when compiling code for distribution on OS X, do people still cross-compile for the i386 architecture? Or are x86_64 binaries the only architecture worth bothering with nowadays?

• Maven2: How do I generate a file that contains the names of the project's dependencies?

  - by Jin Kim

  I would like to place the names of the dependencies in a text file that is distributed inside a package that is built with Maven. I am planning to use the maven assembly plugin to generate the tarball package, and use filtering to put the names in the text file. The only problem is, I don't know how to reference the dependencies in the first place.

• traits in php – any real world examples/best practices?

  - by Max

  Traits have been one of the biggest additions for PHP 5.4. I know the synatax and understand the idea behind traits, like horizontal code re-usage for common stuff like logging, security, caching etc. However, I still dont know yet how I would make use of traits in my projects. Are there any open source projects that already use traits? Any good articles/reading material on how to structure architectures using traits?

• Exiting full screen mode in Flash

  - by OleK

  I am working on a flash game, that will be distributed as and EXE file. I would very much like the game to run full screen, which is not a problem, but I am struggling with replacing flash default behavior when escape is pressed. When escape is pressed I would like to display a custom menu asking the user if they want to exit the game or continue playing, not just exit full screen more. Is this possible in Flash?
