.net - The System.Linq.Dynamic Namespace - Visual Studio Does Not Recognize In The Project Files The System.XXX References
Aug 11, 2011
I would use the System.Linq.Dynamic. I added the specified Dynamic.vb file, that starts like this:

to my (VB.NET)solution. Now Visual Studio does not recognize anymore in the project files the System.XXX references, proposing me to change them to Global.System.XXX

I was trying to finish up a VB.NET class library project when I tried to remove all unused references. I know for a fact that I'm not explicitly using any thing from the System.Xml and System.Xml.Linq assemblies yet the "Unused References..." button never flags them for removal.In fact I even tried "Unused References..." on a blank project and it still never flagged them.

I have a Windows project in Visual Studio 2010 in which I store all images in the project's resource file that Visual Studio created for me. However, it's getting cluttered and I'd like to separate images into multiple resource files if possible. I created a new resource file, but Visual Studio doesn't recognize it when I go to the form designer and try to change an image. The only file that comes up under the Project resource files available are MyProjectResources.resx. The one that I just created isn't there.

I have created a user control which is inside a folder called Controls and the class is a partial class which inherits from Web.UI.UserControl. Now from my page which is one level up I just try to access the method inside the usercontrol and so trying to cast it as the type of user control.
But I get build errors. It just cannot recognize that class. I get Type not defined error. But at times it has recognized the class. Dont know why it does that.

I had a code segment on an asp.net page in the code-behind file. I decided to move it into a public subroutine in a module (general_functions.vb). Once I did this, however, the code no longer works - it throws an error. On the original code-behind I replaced the original code with a call like so:

Just curious. I recently had an incident in which I was called to troubleshoot a VB Winforms app. I have 2 versions of a package (LeadTools) installed on my machine. These packages contain numerous dlls and it is not unusual for a dozen or more to be referenced in a single program.

In my VS2010 VB project I have a lot of external references to DLLs, to the point that organization has become a major headache and I'm wondering if I am going about it the wrong way. My assembly references include common redistributables (SQL Server Compact 3.5 SP1, ReportViewer 2010 SP1, DataVisualization, as well as some useful 3rd party dlls from CodeProject and CodePlex.
Currently, I am copying each DLL into a 1st level folder (/dll_lib) under my named project folder (under the solution folder), and adding the reference from that path. However, I see that Visual Studio copies the DLLs to various other locations (/bin/debug or /bin/release) in my project when I build the project or solution, and some of the 3rd party DLLs come with instructions to copy them manually to /bin.
What is the "best practice" for where to put the DLLs? Can I just put all of them under /bin and let the build event copy to /bin/debug or /bin/release as required? Should I try to force a single reference path for the dlls in the project output?

how can I import the System.ServiceProcess namespace into a WPF project in VB.net (not C#)? The ServiceController object is not in the toolbox in VS2008 and can't see to figure it out. Any ideas? If that particular namespace cannot be imported into WPF projects, could somebody suggest another way of controlling windows services from a WPF application? I know this framework is focused more on multimedia apps, but would really like to switch over some of my tools to WPF.

I was just wondering I heard you can get an on-screen help system, a friend said you can change this in the settings or whatever and when running your application you hit F10 or another key and it will come up with an on-screen help system.

I am just wondering how I can add Direct X references to Visual Basic in Visual Studio 2010 Beta 2. I cant find them in the .NET reference list, or the reference list, or anywhere. I downloaded the Direct X SDK for August 2009, but I can not add the .dll files to the reference list. Is there anything I can do to add them? I need the references for programming reasons.

I've build a large program with many references. F.e.:
System.Data.DataSetExtensions
System.Linq.Dynamic
I've to write a Dynamic Linq Expression: [URL]
In my case: Dim query As IEnumerable = ds.Sales.Where(strWhere)
But with System.Data.DataSetExtensions Where is misinterpreted. The compiler expects (Datarow, Integer, Boolean). If I delete System.Data.DataSetExtensions everything is ok with this expression, but I get many other errors, so I need this reference. What can I do that the Where is interpreted correctly?

I have an desktop application that references several dlls. All are targeted for .Net 3.5, x86. The applicaiton has been deployed for several years and was upgraded from visual studion 2008 to 2010 last year. I have made several changes to the app since then (as recently as last Thursday) with out any issues. Now, everything builds, but when I run the application, I get a type initialiazer error when one of the projects is loaded by the main application.
The error messsage is {"Could not load file or assembly 'System.Drawing, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a' or one of its dependencies. The system cannot find the file specified.":"System.Drawing, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a"}.
There were no changes to this project since the last successfuly deployment last week, but today I am getting this error.

I've decided to learn Visual Basic .Net as this is what some of my colleagues work with, and this will allow me to work with them on projects.I have purchased Microsoft Visual Basic 2010 Step by Step and downloaded the sample files. When I am trying to debug the first sample application (a Windows form), it is telling me that it can't load System.Drawing V4.0.0.0. However, if I create a new Windows Form application (C# or VB.Net) this works fine.
I had a look at the References tab in the project settings and System.Windows.Forms is referenced, but the version referenced is 2.0.0.0. I have removed and re-added this reference and it stays at 2.0.0.0 and I still get the error.Does anybody have any ideas as to what may be going on?

in our project I'm using System.Linq.Dynamic library but I just noticed that I cannot do the folowing:
myDataSource.OrderByDescending("someColumnName")
Because I get the following error:Overload resolution failed because no accessable OrderByDescending can be called with these arguments...
It seems that the Library only support OrderBy("someColumnName"). Is there a reason for this and how would I bypass this issue if I want to reorder the records in descending order? Do I have to user Reverse() for example OrderBy("someColumnName").Reverse()? Seems like a hack...
