• Processor upgrade on a laptop vs. Ram upgrade. Also does ram always matter?

  - by Evan

  I have a Dell Inspiron 14r (N4110) with an Intel Core i3 and 4gb of ram. It runs very smoothly, however gaming on this laptop is very limited. This is mostly because of integrated graphics but i have seen a computer with a Core i5, and very similar specs otherwise, run games that the N4110 cannot. This other computer has integrated graphics and 6gb of ram. I am wondering whether upgrading ram or upgrading the processor make the most difference in performance. Which setup would get better performance, an i5 with 4gb of ram or an i3 with 8 gb of ram? (Both with integrated graphics) Also, is there a certain point at which you have too much ram for the computer to ever possibly use? For instance is there really any difference in performance between 8 gb and 16 gb of ram?

• Local user vs. domain user? What is the right way here?

  - by ebeeb

  I'm a software developer in a company with 6 employees. Everyone has a machine for him-/herself, so none of the machines is shared. I'm currently setting up my machine with Windows 8 and was experimenting a bit with domain and local user accounts. Correct me please if I'm wrong, but I think the idea behind is, that domain users generally should not be able to modify the configuration of a machine (like installing software), since they are able to login on every single machine in the domain. The local user (usually just one local administrator per machine) is the one who cares about the configuration of the machine. But in my case the login into the domain is just for being able to access directories/servers in the domain (I do not really know the details, all I know is, that loggin into the domain user account is necessary). So overall I've got a local admin account and a domain account used on my machine. While working I'm logged in to my domain user account. But it annoys me, that I always need to enter the credentials of my local user account when I'm about to update/install something, which happens quite often as a software developer. I fixed this with adding the domain account into the user accounts in my control panel and putting it into the Administrators group. The only thing I wanted to know about this: is there something REALLY bad about doing this? Or is there maybe a more common way to be able to act like a local admin, while logged in as a domain user? PS: I'm sorry about the tags, but I don't know the proper ones. I'd be glad if some of the superuser experts could fix this :-)

• Install Visual Studio 2010 on SSD drive, or HDD for better performance?

  - by Steve

  I'm going to be installing Visual Studio 2010. I already have my source code on the SSD. For best performance, especially time to open the solution and compiling time, would it be better to install VS 2010 on the SSD or install it on the HDD. If both were on the SSD, loading the VS 2010 files would be quicker, but there would be contention between loading the source and the program files. Thanks!

• Does a receiving mail server (the ultimate destination) see emails delivered directly to it vs. to an external relay which then forwards them to it?

  - by Matt

  Let's say my users have accounts on some mail server mail.example.com. I currently have my mx record set to mail.example.com and all is good. Now let's say I want to have mails initially delivered to an external service (e.g. Postini. Note that this is not a postini-specific question though). In the normal situation where my mx is set directly to my mail server mail.example.com, sending MTAs will of course look up my MX and send to mail.example.com. In my new situation I'd have my mx set to mx.othermailservice.com and emails would be received there. OtherEmailService.com will then relay the emails (while keeping the return-path header the same) to mail.example.com. Do the emails that are received at mail.example.com after be relayed from the other service "look" any different than emails that go directly to it as would be the case where the mx was set to mail.example.com?

• Amazon EC2 - how to determine how busy each CPU is

  - by sally

  I have an Amazon EC2 micro instance. I believe that this is 1 core (or 2 for periodic bursts) with 4 CPU's. I'm getting confused with the terminology (ECU vs CPU vs Core) but really I would like to see how busy each CPU is. When I look at top it seems to be showing me just the cores. I want to see if my process is be spread out across the available processors and how busy each is, what is the appropriate command to do this?

• Oracle (xe) 10 vs 11 . Have I lost the SQL tuning pages ? Am I going out of my mind?

  - by Richard Green

  Ok .. so perhaps the title needs calming down a bit, but basically I am after the xe 11g equivalent of the pages that you can see here : http://docs.oracle.com/cd/B25329_01/doc/admin.102/b25107/getstart.htm#BABHJAGE whcih you can then navigate to stuff like "top 50 queries" and "longest running queries" etc etc. For the life of me, I can't find that on the most recent xe edition. Please can someone direct me to where I might find these very useful admin pages ! Or was I imagining it all along :-/ Edit: These are the pages I am after: http://docs.oracle.com/cd/B25329_01/doc/admin.102/b25107/monitoring.htm

• Searching major search engines with text such as <%#

  - by Daniel Dyson

  If I type '<%# vs <%"' into any of the major search engines, everything is stripped out except the 'vs'. I understand why they do this. I would just like to know if anyone knows of a way to escape illegal characters so that they are searched properly. I know this is not strictly a programming question, but it is relevant.

• WPF, PreviewKeyDown event and underscore char

  - by commanderz

  Hi, I'm catching key hits with PreviewKeyDown event in my WPF component. I need to distinguish characters being typed: letters vs. numbers vs. underscore vs. anything else. Letters and numbers work fine (just convert the Key property of the KeyEventArgs object to string and work with character 0 of that string), but this won't work for underscore. It's ToString value depends on localized keyboard settings (it shows up as "OemMinus" on EN/US keyboard and "OemQuestion" on CZ/QWERTY keyboard). So how can I RELIABLY find out, if the typed char is underscore in the PreviewKeyDown event? Thanks for any help

• Unable to set TestContext property

  - by Brandon

  I have a visual studio 2008 Unit test and I'm getting the following runtime error: Unable to set TestContext property for the class JMPS.PlannerSuite.DataServices.MyUnitTest. Error: System.ArgumentException: Object of type 'Microsoft.VisualStudio.TestTools.TestTypes.Unit.UnitTestAdapterContext' cannot be converted to type 'Microsoft.VisualStudio.TestTools.UnitTesting.TestContext' I have read that VS 2008 does not properly update the references to the UnitTestFramework when converting 2005 projects. My unit test was created in 2008 but it inherits from a base class built in VS 2005. Is this where my problem is coming from? Does my base class have to be rebuilt in 2008? I would rather not do this as it will affect other projects. In other derived unit tests built in 2005, all that we needed to do was comment out the TestContext property in the derived unit test. I have tried this in the VS 2008 unit test with no luck. I have also tried to "new" the TestContext property which gives me a different runtime error. Any ideas?

• Custom app_offline.htm file during publish

  - by Charlino

  When I publish my ASP.NET MVC application it generates a app_offline.htm file to take the site offline while it updates the website and then deletes the file once the publish is successful. This is cool and I really like the idea, but I want to create my own custom app_offline.htm file that the publish action is aware of and put it somewhere where it doesn't effect my development site - i.e. it doesn't sit in the root of my development site rendering it offline all the time. TIA, Charles EDIT: From the comments on Scott Gu's post about app_offline.htm, it seems that customization of the app_offline.htm file wasn't possible with VS 2005 - has this changed with VS 2008 and now VS 2010?

• Cannot find System.Web.Script.Service namespace error after upgrading to Visual studio 2010

  - by Gavin

  I've just upgraded a VS 2008 project to VS 2010, converting the project but keeping the target as .NET 3.5 (SP1 is installed). My project worked without issue under VS 2008 on another machine. I've added references to System.Web.Extensions.dll but I'm still getting the following errors from code in the App_Code folder: 1) Cannot find System.Web.Script.Service namespace 2) Type 'System.Web.Script.Services.ScriptService' is not defined. 3) Type 'System.Runtime.Serialization.Json.DataContractJsonSerializer' is not defined. Anyone have any ideas what the problem might be as I'm pretty stumped? :(

• Fastest way to write large STL vector to file using STL

  - by ljubak

  I have a large vector (10^9 elements) of chars, and I was wondering what is the fastest way to write such vector to a file. So far I've been using next code: vector<char> vs; // ... Fill vector with data ofstream outfile("nanocube.txt", ios::out | ios::binary); ostream_iterator<char> oi(outfile, '\0'); copy(vs.begin(), vs.end(), oi); For this code it takes approximately two minutes to write all data to file. The actual question is: "Can I make it faster using STL and how"?

• Tutorials for .NET database app using SQLite

  - by ChrisC

  I have some MS Access experience, and had a class on console c++ apps, now I am trying to develop my first program. It's a little C# db app. I have the db tables and columns planned and keyed into VS, but that's where I'm stuck. I'm needing C#/VS tutorials that will guide me on configuring relationships, datatyping, etc, on the db so I can get it ready for testing of the schema. The only tutorials I've been able to find either talk about general db basics (ie, not helping me with VS/C#), or about C# communications with an existing SQL db. Thank you. (In case it matters, I'm using the open source System.Data.SQLite (sqlite.phxsoftware.com) for the db. I chose it over SQL Server CE after seeing a comparison between the two. Also I wanted a server-less version of SQL because this little app will be on other people's computers and I want to to do as little support as possible.)

• Sql Server 2008 Install

  - by Steve

  I already have Visual Studio 2008 installed. When installing developer Sql Server 2008, do I need to check the Business Intelligence Development Studio option? I'm guessing not. I assume if I already have VS 2008, the install will just add the relevant Sql Server related project types into VS 2008. EDIT: I marked the question answered before I did the install - I've installed Sql Server before and I thought this was what happened, but on doing this install, leaving the BI studio option unchecked does NOT install the SQL Server projects in Visual Studio. I had to go back and install it, so the answer is... Check it! I was overthinking the install - it's smart enough not to install VS twice.

  - by Kamilos

  Hi, I want to install SQL Server 2008 express. I have already Visual Studio 2008 Team System with SP1. VS in help about shows me: MVS version: 9.0.30729.1 SP .NET Framework version: 3.5 SP1 but installator of SQL Server shows me that Visual Studio doesn't have SP1. Anyway I tricked up him by change in win registry HKLM Software Microsoft DevDiv VS Servicing 9.0 IDE 1033 value from RTM on SP1 and instalation runs. But during instalation error was occured about SP1 again. SQL Server was installed without SQL Managment. When I try install it I have allways the same error about SP1. I was install SP1 couple times with success but it does nothing. I was instal SQL Server SP1 also but it does nothing. Reinstall of VS 2008 and SP1 does nothing. What can I do? Thanks for any help, Kamilos

• How to add flags to RC.EXE through QMake .pro makefiles

  - by Hernán

  I've the following definition in my .pro file: RC_FILE = app.rc This RC file contains a global include at the top: #include "version_info.h" The version_info.h header is on a common header files directory. Since RC.EXE takes INCLUDE environment variable in consideration, according to MS documentation, my build process batch sets up that accordingly: SET INCLUDE=%PROJECTDIR%\version;%INCLUDE% ... QMAKE project.pro -spec win32-msvc2008 -r CONFIG += release This works perfect as RC seems to read that INCLUDE var so the "version_info.h" file is including on every RC file properly. The problem is when I generate a VS solution (or Import it through the VS Addin). The RC invocation does not contain any /I flag (as I expect) but does not read any INCLUDE variable, even when I've setup through system 'environment variables' dialog in XP. So I'm stuck with this problem, with two alternatives I could not get to work: Make VS RC.exe invocation honour the INCLUDE variable (didn't work either as user or system variable). Force QMAKE to pass /I flag to RC invocation, and get that /I flag imported into the project settings (Resource Compiler properties). Thanks in advance.

• Visual Studio 2008/2010 & SQL Server 2008 on Windows 7 Home Premium

  - by Steve

  Are there any limitations with respect to developing ASP.NET and WPF apps using VS 2008/2010 and SQL Server 2008 on Windows 7 Home Premium? I know you can run IIS 7.5 on Home Premium. I Googled and Binged on Home Premium and VS/SQL Server and couldn't find much. It doesn't look like the features missing from Home Premium, domain joining, xp mode, etc... shouldn't prevent one from running and developing in VS/SQL Server. Update I did discover one limitation w/IIS 7.5 and it applies to all versions of Windows 7 I think. You can't create your own self signed SSL certificate specifying a name other than the machine name. You're stuck with your machine name which isn't that big a deal, but it is a change from previous versions.

• Anyone using Moles / Pex in production?

  - by dferraro

  Hi all, I did search the forum and did not find a similar question. I'm looking to make a final decision on our mocking framework of choice moving forward as a best practice - I've decided on Moq... untill I just recently discovered MS has finally created a mocking framework called Moles which seems to work similar to TypeMock via the profiler API sexyness etc.. There's a million 'NMock vs Moq vs TypeMock vs Rhino....' threads on here. But I never see Moles involved.In fact, I did not even know if its existence until a short time ago. Anyone using it? In Production? Anyone dump their old mocking framework for it, and if so, which one? How did it compare to ther mocking frameworks you've used? thanks.. ps, we are using VS2008 and are moving to 2010 shortly.

• Visual Studio 2008 setup looking at wrong drive

  - by Keith G

  I'm trying to add a feature to VS 2008. However, the initial install was done with a DVD in drive D: ... I don't currently have the DVD, so I'm trying to do the updating using an .iso mounted as drive E: ... The VS setup program is not able to find the setup files. Is there a way for me to tell VS 2008 setup to look for files in E: instead of D:? Maybe a registry or ini setting? Edit: The specific error message I got was: A selected drive is no longer valid

• Asp.Net 1 -> Asp.Net 2 upgrade - Machine.Config - unrecognized parameter

  - by Chris

  Hi All, I am working on upgrading a web app to asp.net 2 from 1. VS 2008 did its conversion things, and everything is building successfully and has been converted to a web application via the appropriate menu item in VS 2008. On launching the site using the Asp.net development server I am receiving a configuration error on the appsettings line in the machine config of Unrecognized attribute 'restartOnExternalChanges'. The app targets asp.net 2 in the projects properties in VS, and the error page indicates similar : Version Information: Microsoft .NET Framework Version:2.0.50727.3053; ASP.NET Version:2.0.50727.3053 The error message seems to indicate I am trying to run this in an asp.net 1 environment, but surely that isnt the case, and if so how do I rectify this. Any help would be appreciated Thanks,

• SQL CE not loading from network share

  - by David Veeneman

  I installed VS 2010 RC yesterday, and suddenly, SQL Server CE isn't loading files from a network share. In projects compiled with VS 2008, if I try to open a SQL CE file located on a network share, I get an error that reads like this: Internal error: Cannot open the shared memory region. If I try to create a data connection in VS 2010 to a SQL CE file on a network share, I get this error: SQL Server Compact does not support opening database files on a network share. Can anyone shed any light on what's going on? Thanks.

• Best open source alternative for MS Visual Source Safe?

  - by afsharm

  We are leaving VSS for TFS or any other alternatives. I'm the one who persists to go for an open source alternative like SVN. Now I'm searching for a good open source Version Control regarding following aspects: We are in love with open source movement and cross-platform. Could it be possible to use it with Mono, SharpDevelop and Express editions of VS instead of Visual Studio itself? What about backup? Is it integrated with VS without serious problems? Any API or command prompt access? Please notice I've read following previous texts about it but still need more help: http://stackoverflow.com/questions/690766/vss-or-svn-for-a-net-project http://stackoverflow.com/questions/61959/tfs-vs-open-source-alternatives http://stackoverflow.com/questions/44588/how-to-convince-a-company-to-switch-their-source-control

• Running Visual Studio 2008 and 2010 at the same time

  - by aip.cd.aish

  A group of us are working on a project which we built with .NET 3.5 in Visual Studio 2008. I want to test out Visual Studio 2010 and .NET 4 (well, mainly for WPF 4). I am just wondering if I install VS 2010, will I still be able to use VS 2008 to open the first project. I know when I open older projects made in VS 2003/2005, I get an upgrade wizard. I do not want to upgrade the first project to 2010, since that would probably mean every one else has to use it too. I have not done this before, is it possible to run both versions of Visual Studio, where each version opens its own projects (this may not even be an issue, but I just wanted someone to confirm this, so that I don't spend a lot of time trying to undo changes)?
