I have a few syncing routines that I'd like to use for FTP uploads. However they all use the functions in the IO namespace, and I was wondering whether I could use it to access distant files stored on an FTP server.

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 have a device (a few actually) that connects via USB to a PC. From here it acts like a basic storage device using FAT32 as the file system. The other thing is that it won't accept drive names (C:, E:, G: etc) to it so instead you need to use its Volume GUID to connect. I have retrieved this painlessley through MountVol.exe but thats where the difficulties ended.I am not trying to access the file system through VB.NET/C#.net (either will be fine - fluent in both ;) ). In Windows Explorer I can easily visit '\?Volume{71E4C2C7-E511-4B2A-BF5C-569B2B25784E}apic' to access the device and its files. I can also use CMD and the Dir command to go through the files. Just .NET cant seem to cope. I understand the GUID changes on each PC and I am OK with this as I can use MountVol to get the GUID and run the console app with command arguments as it will always be a human initiating the command.
I have tried manually entering the path via Console.ReadKeys but this also fails to even see the directory above and any of the files inside one being 'dev' without an extention. I can use System.IO operations without extensions on "normal" drives (ie those
with letters) so I know it's not the extension causing problems. I did a Try/Catch with a StreamReader pointing to the file to see what was spurted out:
System.ArgumentException: Illegal characters in path.
at System.Security.Permissions.FileIOPermission.HasIllegalCharacters(String[]
str)

I have a VB Web Site project that has recently (and mysteriously) stopped importing the "System" namespace by default.
I'm having to either place an Imports System line at the top of each code behind, or preface everything with System, which is fairly annoying, not to mention redundant. I can't for the life of me figure out how to get the System namespace back to being imported by default.
I've already checked to see that WINDOWSMicrosoft.NETFrameworkv2.0.50727CONFIGweb.config contains the <add namespace="System"/> line--it does. That was my best lead.
I have references to several namespaces within the System namespace in the <assemblies> node (e.g. System.Design, System.Web.Extensions of my website's web.config. There is no <namespaces> node. This has not been changed recently.
Where is directoryentry, directorysearcher, searchscope, etc.?

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)
View 2 RepliesI'm currently working on an existing ASP.NET project. At the moment I have to integrate
a new componant so for that purpose I had to change the framework target from 2.0 to 3.5. After regenerating the solution, I'm now dealing with a strange issue.
Here's the code :
<WebService(Namespace:="http://tempuri.org/")> _
<WebServiceBinding(ConformsTo:=WsiProfiles.BasicProfile1_1)> _
<Global.Microsoft.VisualBasic.CompilerServices.DesignerGenerated()> _
<System.Web.Script.Services.ScriptService()> _
And the last line returns that error 'ScriptServiceAttribute' is ambiguous in the namespace 'System.Web.Script.Services'I have definitely no clue what's going on in my code ?! Is it an internal error of the ScriptService constructor ?
I have a number of very useful extension methods that I'd like to use in my Silverlight project.I've pasted the Module here [URL]The problem I'm having is that visual studio complains that the dlls my module have been written against have not been built against the Silverlight runtime.Is there an easy way to get these extension methods working in Silverlight?I'm thinking my main hurdle is getting IObjectSet and ObjectContext to run against the Silverlight run-time - perhaps there's another way to expose these methods that I'm not aware of.

I want to add full GPS support into my application. The .Net 4.0 System.Device.Location namespace information here is perfect for my needs. When this was first announced and the Beta release was out, I got a GPS dongle, but I could never get Windows 7 to see it as a sensor and therefore make use of System.Device.Location. After many e-mails to Microsoft they would only confirm that they were using the GPS dongle that comes with a M$ Mapping product..
Does anyone know of any other Dongles that definately will appear as a sensor in Win7? I like the look of this one, it gets good reviews and is a nice size.Is there anyway of knowing that it will work, for example what Chipsets are supported as a Windows 7 Sensor, a lot of the information out there says that the Win7 implementation is really lacking..
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 RepliesI'm setting up a simple XML read-write demo (VB Winforms) in Visual Studio 2010 Premium (tried in both the RC and RTM) and added:
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.
Note: I tried this with the app targeting both .Net 3.5 and 4.0. Same result.
