View 3 RepliesThe type or namespace name 'Messaging' does not exist in the namespace 'System' (are you missing an assembly reference?)
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?)?

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.

I have a large web app in vb.net 4.0. Its default namespace is configured in its project properties. None of the root-level classes in our app are surrounded by namespace declarations. When I add a .asmx file to the root folder of the website, it compiles fine, but it doesn't work for some reason (already asked why in other topics). So to get it to work, I try to surround the class declared in the .asmx by a namespace declaration. As soon as I do this, I go from zero compiler errors to about a zillion. My app can't find ANYTHING in the root namespace. But I haven't changed any other files, only this .asmx file.
WHY is it behaving this way? How do I prevent it from behaving this way without refactoring the entire app? I would love to blank out the default namespace and add them explicitly around every root-level class, but I'm not sure that would fly with our release manager, and I don't even know if it would fix the problem.
I would use the System.Linq.Dynamic. I added the specified Dynamic.vb file, that starts like this:

When we are typing the msconfig in Start>Run the window is appearing that is named System Configuration Utility . Now I want with WMI and API objects access this data and change them by programming in VB6. Specially, I want to change data on Start-up lists and Boot up services Can any one suggest me a solution?
Note: When I am going to use registry datas in compare of System Configuration Utility I have found that all of applications are not listed in registry + startup folder of windows. I think there is a provider for this issue in windows that returns or manages all applications on startup. I am searching for that.

I have a VS Solution with several projects. I want to set a specific project to the start project in Debug mode.

My app downloads multiple files, and its limited to 2 connections. Now I've read you can change this, by adding the following in the app.config file:
CODE:
And that does work, however I would like to hardcode it in, rather than use app.config file.
I've tried (importing System.Net.Configuration):
CODE:
But that doesn't work, still stays limited to 2 connections total.
I am trying to execute a VB .net console application called Application1 that I created using Visual Studio 2008 with .net framework 3.5. When I run it under the windows scheduler or from a command prompt it works fine. When I try to run it under a purchased job scheduler, I get a message stating that directory APPLIC~1.config is missing. What properties does system.configuration use when it tries to find an application's .config file? Can these be set when my application starts?
Note: I was able to use ConfigurationManager.OpenExeConfiguration(My.Application.Info.DirectoryPath & "" & My.Application.Info.AssemblyName & ".exe") to get around this issue but would like a cleaner solution. I do not want to do this each time I want to retrieve an appSetting entry.

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?
