I can't import the System.DirectoryServices namespace. It doesn't pop up if that little box thing.Why?
View 2 RepliesI just converted UberSite, a vb.net web site to a web application. I get run-time errors saying that there is no such thing as type foo. When I drill down to the page in the code-view, it gives me an error-correction suggestion: import namespace UberSite.
If I create a new web application and define foo there, there is no need to import any namespace to use foo in the new application.
How can this be? Why does my web application seemingly need to import its own namespace?
I put this on a file

In my application there is a feature that lets you get the current song from itunes, but itunes opens up upon my applications launch.
So I'm assuming that it is opening when:
Imports iTunesLib
Is called. Is there a way that I can import something after a launch, and on a event, like a button push?
I can't seem to find a clear answer as to how to import the proper namespace for ReportingService [URL]. I tried to follow the instruction here [URL] but there is no Add Web Service option showing when I create a console application. There is a service account. Should I just use that instead?
View 2 RepliesI have a bizarre vb.net problem.I'm working with a 3rd party library with a namespace called Telerik.Webcontrols. The library is in a web site project that I am in the process of converting to a web application project.
Telerik.WebControls contains a class called RadAjaxControl.In the original web site project, I have code that looks like this:
public sub page_load(...)
dim foo as Telerik.Webcontrols.RadAjaxControl
Once I convert to a web application project, it says that Telerik.Webcontrols doesn't exist.
However, the truly bizarre thing is that the following code does compile:
imports Telerik.WebControls public sub page_load(...)dim foo as RadAjaxControl
I am having problem with importing Crystal Report, each time I type the following commands, they are underlined:
Imports CrystalDecisions.CrystalReports.EngineImports CrystalDecisions.SharedImports System.Data
It tells me the namespace dosen't contain any public member. So I am unable to declare any crystal report object because the namespace is refusing to be imported.

View 1 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.
I got a graphic that I got to rotate about a specific point. So, I got to define the centerX and centerY, the point about which to rotate. For that, I am importing the namespace: "system.windows.media.rotatetransform"The following problem then arises when the above namespace gets underlined with a green curly line and when I place the mouse over it, the following message is displayed:"Namespace or type specified in the Imports'System.Windows.media.rotatetransform' doesn't contain any public member or cannot be found. Make sure the namespae or type is defined and contains at least one public member. Make sure the imported element name doesn't use any aliases."
View 4 Replieshow 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 RepliesThis class is located in the namespace Acme.Infrastructure.Interface.A class with the same name EventArgs exists in the System namespace.In another project in my solution I have a class Acme.BusinessModules.MyModule.MyClass.When attempting to use the EventArgs class I have to fully qualify the class name or the compiler thinks I am using the System.EventArgs class.My understanding of namespace resolution was that the compiler would first look for the class in the current namespace, and then its parents. It seems that the compiler checks in System before it checks in sibling namespaces. Is it correct that System is checked before the sibling? Or is this behaviour caused by other issues (Imports order?)?

I've currently got a class that has a bunch of functions within it that I'd like to group up. I can't seem to find a way to do this, as the functions interact with the objects within the class (so I can't use a structure for example). Namespaces are only allowed outside of Classes as are modules. Let's say I have Class Foo. Inside Class Foo there are six functions, three that are logically grouped together and another three that are as well.
Class Foo
Public Function moneyFoo1()
Public Function moneyFoo2()
Public Function moneyFoo3()

I VB 2005 you can set the root namespace name of a project under the project properties. Where can I set this using VB2008?

When you develop a class library that will be used by others, are there any guidelines on how you decide what namespace to put it under? I often find third party classes just use the company name as the root namespace but I was also wondering if it is frowned upon (or even possible) to add one of your own classes to an existing framework namespace.

Which is the best way to store global variables, in My.Settings or My.Namespace. The reason I ask is because I need to know certain boolean values if certain forms are open from other forms. At present I am defining Global Boolean variables in My.Application, which give the result I require.
View 3 Replies[URL] The jist of the problem is in fact that in the weka.classifiers.trees namespace you have the following members:

and
public class J48 : weka.classifiers.Classifier (Member of weka.classifiers.trees)
Lamentably VB .NET in VS 2008 does not seem to be smart enough to distinguish betweem the two (which is odd, because there is no such problem in VS 2003, or in C# in VS 2008) because of it's lack of case sensitivity. Or possibly because of the fact that ikvmc emits an assembly compiled for the 1.1 run time... I'm not sure. I'm also not quite sure how you would resolve this particular issue and given the time sensitivity of this project I do not have the time to learn C# or Java to an extensive degree.

I am trying to import some hex data into the registry with my program.
Instead of importing it as a binary type, I need to import it as RegistryValueKind.ExpandString. What is the proper way to convert this over to import it?
