I'm developing an web application using VB.Net, and I would like to know, if is there any way to make a namespace to be viewed by all project without necessary Imports?
View 1 RepliesI've started to use a Vista machine for development. In case it is significant: I'm using MSBee so that I can code in the Visual Studio 2005 IDE while still building against the 1.1 framework.On the Vista machine, when I tried to build a particular vb project, I got this error:
error BC30464: Namespace or type'Compatibility' in the project-level Imports 'Microsoft.VisualBasic.Compatibility' cannot be found.
The same project built fine on my old XP machine. I checked in this folder on my Vista machine:
C:windowsmicrosoft.netFrameworkv1.1.4322
...and sure enough, "Microsoft.VisualBasic.Compatibility.dll" was missing. So was "Microsoft.VisualBasic.Compatibility.Data.dll". Copying them from my XP machine to my Vista machine allowed me to build the project successfully.I'm just a bit puzzled as to why this happened. Why was "Microsoft.VisualBasic.Compatibility.dll" missing? I'm also not very comfortable with my chosen solution - copying the DLL manually. It works, but surely there must be a better way.
As far as the configuration:
Vista:
.Net Framework 1.1
.Net Framework 1.1 SP1
.Net Framework 1.1 SDK

In my Solutions in Visual Studio, I have 3 projects.
- Common (Root namespace: PodcastPlayer.Common)
-PodcastPlayer (Root namespace: PodcastPlayer) This is the Silverlight project.
-PodcastPlayer.Web (Root namespace: PodcastPlayer.Web)
In Common, I have several classes and service references.But my problem is that I can`t not use PodcastPlayer.Common namespace in PodcastPlayer project.
I knew from here that we have to do the explicit imports for child namespace because imports will not include the child namespace.But my question is that if I do "imports System" whether it will include all the classes/methods inside that namespace in the IL/native code or only referred ( used inside the application) will be included in the IL/native code.

Imports System.Xml
Result: Error Namespace or type doesn't contain any public members or cannot be found...
VS 2008 equivalent example recognizes the Imports statement fine.I know this has to be me, but I'm stumped.

I have a WPF VB.NET project in Visual Studio 2008. For some reason, Visual Studio thinks that it needs to add anImports MS.Internal.Xaml.Builtinsto every auto-generated XAML partial class (= the nameOfXamlFile.g.vb files), resulting in the following warning:warning BC40056: Namespace or type specified in the Imports 'MS.Internal.Xaml.Builtins' doesn't contain any public member or cannot be found. Make sure the namespace or the type is defined and contains at least one public member. Make sure the imported element name doesn't use any aliases.I can remove the Imports line, but, since this is an auto-generated file, it reappears every time that the project is rebuilt.

Imports xyz = ProjectABC.ClassABC
But if I want to use the Project Properties, Reference tab to select a namespace to allow a project-wide setting, is it possible to alias that namespace?
I have a Web Service Application Project in Visual Studio 2008. This is supposed to be an ASP.Net 2.0 project and at some point this has been rebuilt using 3.5.VS has kindly added in project level imports to System.Linq and System.Xml.Linq, but when I have re-targeted the project at 2.0 these project level imports have remained.Because the Web Service Application Project does not have the detailed window for editing project references I cannot find how to remove these project level imports.There is no .proj file which is where I would assume these were included.I cannot now build the project as it fails, even though I only get warnings (no errors reported) such as this:Namespace or type specified in the project-level Imports 'System.Linq' doesn't contain any public member or cannot be found. Make sure the namespace or the type is defined and contains at least one public member. Make sure the imported element name doesn't use any aliases.

Im using Visual Basic Express 2010.This is from a tutorial in Microsoft Visual Basic 2010 Step by Step
a common VB.NET class should look like the following:
Public Class MyClassName
End Class
Besides, I have already seen, if I remember correctly, all of the import statements visible just like in C#:
Imports System
Imports System.Data
Imports System.Linq
Public Class MyClassName
End Class
How to make these default imports visible by default in VB.NET using Visual Studio 2008?Is there some setting or the like in the options I shall set?
Generally speaking, a common VB.NET class should look like the following:Public Class MyClassNameEnd Class
View 1 RepliesI have 2 projects, one built in VB.NET and another in C#.NET. I want to use certain functionality of VB.NET into C#.NET and hence I have added the dll file of VB.NET solution into C#.NET as a reference by browsing the dll from my system. Say dll name for VB.NET is myData.dll. In my C#.NET project I am trying to declare it as a namespace i.e. "using myData;" and its giving me an error of "Type or namespace name could not be found"
View 1 RepliesI have a vb.net 3.5 class library project that needs to reference two assemblies that have the same namespace. We have two third party dll's in which one is version 5.1 and the other is version 6.1. They have the same dll filename and they utilize the same namespace and functions/class names. The project needs to use one or the other depending on a specific situation. I've investigated up on a c# process that uses the "extern alias" feature to pull in the different assemblies.
[URL]
What use is the Aliases property of assembly references in Visual Studio 8.It seems that this feature isn't fully available for vb.net. Things I've Tried I've renamed the 2nd dll and added both references to my project. At this point I get tons of: 'blah' is ambiguous in the namespace. So I need to alias the different versions. In vb.net you can do aliases on an imports statement like:
Imports version5 = Somedll.Something
The problem is I can't setup an assembly reference alias for the different versions of the dll. Apparently in vb.net you can't set these up in the reference properties window. So I tried setting them in in my project file like this:
<Reference Include="somedll.5.Navigation">
<HintPath>....UtilityThirdPartyDLLSsomedll.5.dll</HintPath>
<Aliases>SomeDLL5</Aliases>
[code]....
I would then expect this to work:
Imports version5 = SomeDLL5.Something
Imports version6 = SomeDLL6.Something
But the "SomeDLL5/6" doesn't show up in intellisense. So how can I reference both dll's in the same project?
I'm trying to make more use of namespaces and giving my project a more rigorous design, as it has been getting pretty messy.I was wondering,before I get started, is there a standard convention for the names and organization of namespaces?For instance,for a 3-tier program, should there always be a "UI", "Business",and "DataAccess" namespace (and is this what they're typically called)?Or should I just organize the project as I see fit?

View 1 RepliesI have an VS2008 solution with 2 projects, WebUI and Domain; WebUI references domain. The Root Namespace in the WebUI project is:MyCompany. MyProjectName.WebUI. The Root Namespace in the Domain project is blank. (Namespaces are manually declared for all classes). So everything has been working fine, until I tried to reference a class in Domain via a fully qualified path: [Code]
Does this make any sense? So, then I cleared my WebUI Root Namespace, and voila, the fully qualified declaration then does work. However, doing this then seemed to invalidate the registration of all my user controls on my pages. The only thing that seemed to solve this was in the codebehind of each user control, manually add a namespace of MyCompany.MyProjectName.WebUI. which might make sense as perhaps the namespaces of the pages somehow had still retained the root namespace value. But, if I was to create a brand new aspx page and drop a user control on (this is before manually adding the namespace), even that page couldn't properly register it. Yet, the user control properly rendered in design view. so the VS UI seemed to be able to properly resolve it, but the compiler seemingly can't.
So from what I can tell, I can at least get things to work by manually wrapping user controls in the proper namespace. Why this is necessary for aspx pages, that have no namespace specified, to see the user controls, seems to make no sense. Is there some fundamental principle I am misunderstanding??
I VB 2005 you can set the root namespace name of a project under the project properties. Where can I set this using VB2008?
View 4 RepliesI am trying to create a custom LabelFor helper to apply by default instead of the standard LabelFor helper include in System.Web.Mvc.Html. I want my LabelFor to take model properties that are PascalCase and make a label that appears as multiple words. For example the property FirstName would appear as "First Name".
I found this post that shows how to make a custom LabelFor helper that allows the addition of html attributes. I recreated this helper in VB.Net and modified it to do what I want, but I am not able to get it to work.
[Code]...
The sample includes this Module in Namespace System.Web.Mvc.Html but when I add the namespace declaration to this module everything in the rest of the project goes haywire. For example, each of my models has a Primary Key property that is a Guid datatype and as soon as I add the namespace above to the module, I get several errors stating that System.Guid is not defined among other similar errors.
I've tried to import my project namespace into a view in order to use the custom helper, but then I get an error that says Overload resolution failed because no 'LabelFor' is most specific for these arguments.I am trying to avoid having to specify a DisplayName for every PascalCase property I have in many models.
Is that possible to create a class in vb.net that is not in the default namespace of the project?
for example, say you have a project call sample1, then automatially IDE will have everything default to the Sample1 as your namespace root rather than under global, which is find for most case.but I want to create some classes that is directly under global namespace
I've just picked up a project from someone who has recently left our company, and the project file for the project has somehow had XML documentation deactivated. Typing ''' no longer automatically creates XML documentation segments, and existing XML documentation within the code does not show up in Intellisense, and is also not correctly highlighted as XML documentation.
In addition, the Intellisense for the My. namespace contains only MySettings, Resources and Setting under the "All" tab. Everything else is missing. Attempting to manually write My. namespace code results in compile errors. These are not problems with the IDE; I can start a new project and both Intellisense and My. work fine in these new projects. I can only assume that this is something which has been set on the project itself.
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.
View 2 RepliesHow does one gain programatic access to the information that is entered into the "My Project" properties Application section?I am able to pick up the assembly name from those properties, but I haven't been able to pick these up.Below is the line of code that makes me interested in picking this up programatically.

I am working on a solution that does not name namespaces in code files. Instead it uses the root name space of the project (which is the same across all assemblies). Basically there is only one implicit namespace.
Well, I am trying to isolate some code so that I can run FxCop against it. I explicated named the code file with a namespace to do this. This works for FxCop, but it bricks the entire solution.Visual Studio is now asking me to prefix all uses of the implicit namespace with Global. So instead of:
[Code]...
I got some set of base classes within one namespace and few sets of derived classes in other namespaces. Everything in one project.[code]...
OK, it can be done declaring .SubElements as Protected in BaseElement class. But in this case I cannot access this property from other classes in Base namespace that are not derived from it.
I tried adding Friend keyword, but it made this property visible when I'm instantiating derived classes too.
So... any way to hide some properties when using derived classes while being able to use them using base class?
Would there be a way to make the system.drawing namespace available to a console application? ( i know this sounds silly, but all my application does is take a bitmap of a window and saves it to file, so whats the point in my application being form based)
