  • Should I avoid SharePoint Development in Visual Studio?

    - by SaphuA
    Not long ago I started an internship at a company that supplies SharePoint consultancy, hosting and development. While their consultancy seems to be pretty good and solid, I feel their development department lacks direction. The reason for this, most likely, is that they stopped outsourcing not too long ago. One thing that I've frequently bumped my head into is the following: My supervisor strongly insists that everything that can be done natively in SharePoint (somehow this includes editing xslt files in Designer) should be done in SharePoint. Even if this results in longer development time (at least when they make me write XSLT) and reduced usability. Her main arguments for this are: Better maintainability Editing the functionality doesn't require programming knowledge I feel the company is a little biassed and I am unable to get a decent discussion going. This is why I am looking for other places to get some responses on the subject (and not only on the arguments of my supervisor, but more on the subject in general). Kind regards

  • Page Inspector and Visual Studio 2012

    - by nikolaosk
    In this post I will be looking into a new feature that has been added to theVS 2012 IDE. I am talking about Page Inspector that gives developers a very good/handy way to identify layout issues and to find out which part of server side code is responsible for that HTML snippet of code.If you are interested in reading other posts about VS 2012 and .Net 4.5 please have a look here and here.This tool is integrated into the VS 2012 IDE.We can launch it in different ways. 1) We will create a new ASP.Net MVC application (an Internet application). I will not add any code.2) In the Solution Explorer I choose my project and right-click. From the available options select View in Page InspectorHave a look at the picture below.  3) We can launch Page Inspector from the Standard Toolbar. Please have a look at the picture below.   4) Let's view our application with Page Inspector. First I inspect the About link-menu.I can see very quickly the HTML that is rendering for that link to appear. I also see the server side code (the actual view, _Layout.cshtml) that is responsible for that link. This is something developers always craved for. We can also see the CSS styles that are used to style this link (About).Have a look at the picture below Obviously there are similar tools that I have been using in the past when I wanted to change a part of the HTML or see what piece of CSS code affects my layout. I used Firebug when viewing my web applications in the Firefox browser. Internet Explorer and Chrome have also great similar tools that help web developers to identify issues with a site's appearance/issues.Please bear in mind that Page Inspector works with all forms of the ASP.Net stack e.g Web Forms,Web Pages.Hope it helps!!!!!

  • Best approach for utility class library using Visual Studio

    - by gregsdennis
    I have a collection of classes that I commonly (but not always) use when developing WPF applications. The trouble I have is that if I want to use only a subset of the classes, I have three options: Distribute the entire DLL. While this approach makes code maintenance easier, it does require distributing a large DLL for minimal code functionality. Copy the classes I need to the current application. This approach solves the problem of not distributing unused code, but completely eliminates code maintenance. Maintain each class/feature in a separate project. This solves both problems from above, but then I have dramatically increased the number of files that need to be distributed, and it bloats my VS solution with tiny projects. Ideally, I'd like a combination of 1 & 3: A single project that contains all of my utility classes but builds to a DLL containing only the classes that are used in the current application. Are there any other common approaches that I haven't considered? Is there any way to do what I want? Thank you.

  • WiFi and Bluetooth will not work on Dell Studio XPS 1645

    - by Ross
    Today I acquired a Dell XPS 1645. Ubuntu seems to run alright on it however The bluetooth is not detected and the WiFi doesn't work. The WiFi is especially weird because I actually have the restricted driver enabled for it. It also worked for a short while when I first booted into Ubuntu however now there isn't even an option to enable wireless. If anyone could possibly help me out with this I'd deeply appreciate it. I've not had to return to Windows for a good while and it's not something I want to have to do now.

  • Overheating on Dell Studio XPS 1645

    - by pjtatlow
    So I was wondering if anyone else has come upon this problem, and/or has come up with a solution. When I use my Ubuntu partition, my computer becomes extremely hot, and the fan runs very noisily for a very long time. If I reboot into windows while this is happening, my computer actually begins to cool down while doing the exact same tasks. Thinking this might just be a bug with Ubuntu, I installed fedora on another partition, and the same problem occurs. Is this a problem with the kernel? Cpufreq tells me that my CPU is running at 933 MHz out of a possible 1.6 GHz from my Intel Core i7 CPU Q70. For anyone who wants more information, I have 8 GB of memory, and an ATI Mobility Raedon HD 5730 Graphics Card. I'm open to any ideas anyone might have. Thanks in advance!

  • Visual Studio 2010 editor painfully slow

    - by Daniel Gehriger
    I'm running out of patience with MS VisualStudio 2010: I'm working on a solution containing ~50 C++ projects. When using the editor, I experience a lag of 1 - 2 seconds whenever I move the cursor to a different line, or when I move to a different window, or generally when the editor losses and gains focus. I went through a whole series of optimizations, to no avail: installed all hotfixes for VS2010 disabled all add-ins and extensions disabled Intellisense deleted all temporary files created by VS2010 disabled hardware acceleration unloaded all but 15 projects disabled tracking changes closed all but one window and so on. This is on a Dual Core machine with SSD harddrive (verified throughput 100MB/s), enough free space on HD, Windows 7 Pro 32-bit with 3GB of RAM and most of it still free. Whenever I type a letter, CPU usage of devenv.exe goes to 50 - 90% in process monitor for 1 - 2 seconds before returning to 5%. I used Process Explorer to analyze registry and file system access, and I only notice frequent accesses to the .sln file (which is quiet small), and a few registry reads, but nothing that would raise a red flag. I don't have this problem with solutions containing less projects, so I'm inclined to think that it's related to the number of projects. For your information, the entire solution has been migrated over the years from VS2005 to VS2008 to now VS2010. Does anyone have any ideas what else I could do to resume work on this project, other than returning to VS2008?

  • converting dates things from visual basic to c-sharp

    - by sinrtb
    So as an excercise in utility i've taken it upon myself to convert one of our poor old vb .net 1.1 apps to C# .net 4.0. I used telerik code conversion for a starting point and ended up with ~150 errors (not too bad considering its over 20k of code and rarely can i get it to run without an error using the production source) many of which deal with time/date in vb versus c#. my question is this how would you represent the following statement in VB If oStruct.AH_DATE <> #1/1/1900# Then in C#? The converter gave me if (oStruct.AH_DATE != 1/1/1900 12:00:00 AM) { which is of course not correct but I cannot seem to work out how to make it correct.

  • Simple alternating text in Visual Basic 2008

    - by Josh Grate
    I have a simple completed program, but i would like to add one more feature to it but I'm not sure how. I have it set up to send a message automatically every 7 seconds when a text field is selected, repeating the message of course. What I would like for it to do is alternate between two separate messages, instead just repeating the one. I would like the new program to post at an interval of 12 seconds. Can you help me? Here is my coding. Public Class Form1 Private Sub Timer1_Tick(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Timer1.Tick SendKeys.Send(TextBox1.Text) SendKeys.Send("{ENTER}") End Sub Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click Timer1.Enabled = True Timer1.Interval = (TextBox2.Text) End Sub Private Sub Button2_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button2.Click Timer1.Enabled = False End Sub Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load Timer1.Enabled = False End Sub End Class

  • What does Visual studio debugger do, when condition should give error

    - by zacharmarz
    I'm debugging some code and I need to break everytime, when character in string (const char *) is equal to something. So I put there breakpoint and attach condition like: s[0] == 'e'. But code I'm debugging is in CRT and there is possibility, that s == 0 is true. So "addressing empty pointer" should give some kind of error. Yes - I could give there condition s != 0, but it would not be such fun :) And I'm curious, what will debugger do when trying to evaluate this condition? How it will behave internally? Obviously it's not giving any error nor stopping on this breakpoint when s == 0 Thanks for your answer.

  • Writing scripts for Visual Studio project

    - by oillio
    What is the best way to write and run small scripts and tasks that are specific to a particular .Net project? Such things as configuring a database or confirming proper connections to servers. In Ruby, I would build rake tasks for this sort of thing. I am currently using unit tests for these tasks as they are easy to run within VS and they have access to all the necessary libraries and project code. However, this is not really their intended purpose and, with the dropping of Test Lists in VS 2012, it does not work nearly as well as it used to. Is there a better solution than writing a console project to handle these little code snippets I need to run periodically?

  • Good practice on Visual Studio Solutions

    - by JonWillis
    Hopefully a relativity simple question. I'm starting work on a new internal project to create tractability of repaired devices within the buildings. The database is stored remotely on a webserver, and will be accessed via web API (JSON output) and protected with OAuth. The front end GUI is being done in WPF, and the business code in C#. From this, I see the different layers Presentation/Application/Datastore. There will be code for managing all the authenticated calls to the API, class to represent entities (business objects), classes to construct the entities (business objects), parts for WPF GUI, parts of the WPF viewmodels, and so on. Is it best to create this in a single project, or split them into individual projects? In my heart I say it should be multiple projects. I have done it both ways previously, and found testing to be easier with a single project solution, however with multiple projects then recursive dependencies can crop up. Especially when classes have interfaces to make it easier to test, I've found things can become awkward.

  • SmartOS reboots spontaneously

    - by Alex
    I run a SmartOS system on a Hetzner EX4S (Intel Core i7-2600, 32G RAM, 2x3Tb SATA HDD). There are six virtual machines on the host: [root@10-bf-48-7f-e7-03 ~]# vmadm list UUID TYPE RAM STATE ALIAS d2223467-bbe5-4b81-a9d1-439e9a66d43f KVM 512 running xxxx1 5f36358f-68fa-4351-b66f-830484b9a6ee KVM 1024 running xxxx2 d570e9ac-9eac-4e4f-8fda-2b1d721c8358 OS 1024 running xxxx3 ef88979e-fb7f-460c-bf56-905755e0a399 KVM 1024 running xxxx4 d8e06def-c9c9-4d17-b975-47dd4836f962 KVM 4096 running xxxx5 4b06fe88-db6e-4cf3-aadd-e1006ada7188 KVM 9216 running xxxx5 [root@10-bf-48-7f-e7-03 ~]# The host reboots several times a week with no crash dump in /var/crash and no messages in the /var/adm/messages log.

We do not have physical or virtual access to the server console - no KVM, no iLO or anything like this. So, the only way to debug is to analyze crash dumps/log files. I am not a SmartOS/Solaris expert so I am not sure how to proceed. Is there any equivalent of Linux netconsole for SmartOS? Can I just redirect the console output to the network port somehow? Maybe I am missing something obvious and crash information is located somewhere else.

  • broken upgrade from 10.04 to 12.04 on a VPS - recoverable?

    - by HorusKol
    I have a VPS hosted 1500 km away. It originally came with 9.10 - and this morning I decided that I really should get to an LTS release, and figured I'd jump to 12.04. Researching, I discovered that there is no direct path between 9.10 and 12.04, but that I could upgrade via 10.04. After backing up my data, I dove in. The upgrade to 10.04 was successful, and I proceeded to upgrade to 12.04. Things started to go wrong. First, I got an error with GLIBC - I retried and got the same error. That's when I stopped the upgrade. I then tried another round of apt-get update && apt-get upgrade and got a list of "unmet dependencies": apt: Depends: ubuntu-keyring but it is not going to be installed Depends: libc6 (>= 2.15) but 2.11.1-0ubuntu7.11 is to be installed Depends: libstdc++6 (>= 4.6) but 4.4.3-4ubuntu5.1 is to be installed PreDepends: dpkg (>= 1.15.7.2) but 1.15.5.6ubuntu4.6 is to be installed apt-utils: Depends: libapt-pkg-libc6.10-6-4.8 libapt-inst1.4: Depends: libc6 (>= 2.14) but 2.11.1-0ubuntu7.11 is to be installed libapt-pkg4.12: Depends: libc6 (>= 2.15) but 2.11.1-0ubuntu7.11 is to be installed Depends: libstdc++6 (>= 4.6) but 4.4.3-4ubuntu5.1 is to be installed libc6: Depends: libc-bin (= 2.11.1-0ubuntu7.11) but 2.15-0ubuntu10.2 is to be installed libept0: Depends: libapt-pkg-libc6.10-6-4.8 libnih-dbus1: Depends: libnih1 (= 1.0.3-4ubuntu9) but 1.0.1-1 is to be installed I tried to see if I could do something about these - using apt-get -f install. This told me that I would need to upgrade my kernel. I found instructions on how to do this, but when I ran apt-get to install the new linux headers, I got the same dependency errors. I found another answer here where someone else had had an interruption in their upgrade - and tried the solution that worked for them: sudo apt-get -f dist-upgrade This resulted in the error: E: Could not perform immediate configuration on 'python2.7-minimal'.Please see man 5 apt.conf under APT::Immediate-Configure for details. (2) I tried to resolve this by: apt-get install -o APT::Immediate-Configure=false -f apt python-minimal But this simply ended up with this last list of dependency errors: apt: Depends: ubuntu-keyring but it is not going to be installed Depends: libc6 (>= 2.15) but 2.11.1-0ubuntu7.11 is to be installed Depends: libstdc++6 (>= 4.6) but 4.4.3-4ubuntu5.1 is to be installed PreDepends: dpkg (>= 1.15.7.2) but 1.15.5.6ubuntu4.6 is to be installed apt-utils: Depends: libapt-pkg-libc6.10-6-4.8 libapt-inst1.4: Depends: libc6 (>= 2.14) but 2.11.1-0ubuntu7.11 is to be installed libapt-pkg4.12: Depends: libc6 (>= 2.15) but 2.11.1-0ubuntu7.11 is to be installed Depends: libstdc++6 (>= 4.6) but 4.4.3-4ubuntu5.1 is to be installed libc6: Depends: libc-bin (= 2.11.1-0ubuntu7.11) but 2.15-0ubuntu10.2 is to be installed libept0: Depends: libapt-pkg-libc6.10-6-4.8 libnih-dbus1: Depends: libnih1 (= 1.0.3-4ubuntu9) but 1.0.1-1 is to be installed python: Depends: python-minimal (= 2.6.5-0ubuntu1) but 2.7.3-0ubuntu2 is to be installed python-apt: Depends: libapt-pkg-libc6.10-6-4.8 python-minimal: Depends: python2.7-minimal (>= 2.7.3) but it is not going to be installed Breaks: python-support (< 1.0.10ubuntu2) but 1.0.4ubuntu1 is to be installed synaptic: Depends: libapt-pkg-libc6.10-6-4.8 Any ideas on how to dig out of this hole?

  • Returning std::vector by value

    - by deft_code
    It is oft said that in C++11 it is sane to return std::vector by value. In C++03 this was mostly true as RVO should optimize away the copy. But that should scared most developers away. In C++11 will a returned std::vector local variable always be moved? What if that vector is a member of a local variable instead of a local variable itself? Obviously returning a global variable will not be moved. What other cases will it not be moved?

    Almost everyday my server is crashing due to hight server load, and even restarting apache or mysql can't solve the problem.

But it looks that the solution is just to update the kernel or disk driver, thinks that I don't know how to do. In this url http://bugs.centos.org/view.php?id=4515 a lot o people report similar problems, except the fact that they are not related to httpd like mine. According to one member, one solution would be to add "elevator=noop " to /etc/grub.conf like in this example: title CentOS (2.6.18-238.12.1.el5xen) root (hd0,0) kernel /vmlinuz-2.6.18-238.12.1.el5xen ro root=/dev/VolGroup00/LogVol00 elevator=noop initrd /initrd-2.6.18-238.12.1.el5xen.img Would this really solve the problem? My disk are working in RAID. Can this cause some problem to my server? Is there any other solution?

  • Visual Basic 2010 Language Enhancements

    Earlier this month Microsoft released Visual Studio 2010, the .NET Framework 4.0 (which includes ASP.NET 4.0), and new versions of their core programming languages: C# 4.0 and Visual Basic 10 (also referred to as Visual Basic 2010). Previously, the C# and Visual Basic programming languages were managed by two separate teams within Microsoft, which helps explain why features found in one language was not necessarily found in the other. For example, C# 3.0 introduced collection initializers, which enable developers to define the contents of a collection when declaring it; however, Visual Basic 9 did not support collection initializers. Conversely, Visual Basic has long supported optional parameters in methods, whereas C# did not. Recently, Microsoft merged the Visual Basic and C# teams to help ensure that C# and Visual Basic grow together. As explained by Microsoft program manager Jonathan Aneja, "The intent is to make the languages advance together. When major functionality is introduced in one language, it should appear in the other as well. ... [T]hat any task you can do in one language should be as simple in the other." To this end, with version 4.0 C# now supports optional parameters and named arguments, two features that have long been part of Visual Basic's vernacular. And, likewise, Visual Basic has been updated to include a number of C# features that it was previously missing. This article explores some of these new features that were added to Visual Basic 2010. Read on to learn more! Read More >Did you know that DotNetSlackers also publishes .net articles written by top known .net Authors?

  • Now Available: Visual Studio 2010 Release Candidate Virtual Machines with Sample Data and Hands-on-L

    - by John Alexander
    From a message from Brian Keller: “Back in December we posted a set of virtual machines pre-configured with Visual Studio 2010 Beta 2, Visual Studio Team Foundation Server 2010 Beta 2, and 7 hands-on-labs. I am pleased to announce that today we have shipped an updated virtual machine using the Visual Studio 2010 Release Candidate bits, a brand new sample application, and 9 hands-on-labs. This VM is customer-ready and includes everything you need to learn and/or deliver demonstrations of many of my favorite application lifecycle management (ALM) capabilities in Visual Studio 2010. This VM is available in the virtualization platform of your choice (Hyper-V, Virtual PC 2007 SP1, and Windows [7] Virtual PC). Hyper-V is highly recommended because of the performance benefits and snapshotting capabilities. Tailspin Toys The sample application we are using in this virtual machine is a simple ASP.NET MVC 2 storefront called Tailspin Toys. Tailspin Toys sells model airplanes and relies on the application lifecycle management capabilities of Visual Studio 2010 to help them build, test, and maintain their storefront. Major kudos go to Dan Massey for building out this great application for us. Hands-on-Labs / Demo Scripts The 9 hands-on-labs / demo scripts which accompany this virtual machine cover several of the core capabilities of conducting application lifecycle management with Visual Studio 2010. Each document can be used by an individual in a hands-on-lab capacity, to learn how to perform a given set of tasks, or used by a presenter to deliver a demonstration or classroom-style training. Unlike the beta 2 release, 100% of these labs target Tailspin Toys to help ensure a consistent storytelling experience. Software quality: Authoring and Running Manual Tests using Microsoft Test Manager 2010 Introduction to Test Case Management with Microsoft Test Manager 2010 Introduction to Coded UI Tests with Visual Studio 2010 Ultimate Debugging with IntelliTrace using Visual Studio 2010 Ultimate Software architecture: Code Discovery using the architecture tools in Visual Studio 2010 Ultimate Understanding Class Coupling with Visual Studio 2010 Ultimate Using the Architecture Explore in Visual Studio 2010 Ultimate to Analyze Your Code Software Configuration Management: Planning your Projects with Team Foundation Server 2010 Branching and Merging Visualization with Team Foundation Server 2010 “ Check out Brian’s Post for more info including download instructions…
