.net - What GPS Dongles Work With Windows 7 And The .Net 4.0 System.Device.Location Namespace
Jun 29, 2010
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..
A Problem in accessing a device from VB Windows cannot load the device driver for this hardware because there is a duplicate device already running in the system. (Code 42) This error is because i am using 2 devices of the same company which has the mass usb storage on it and when i install one of the device the other hides. So one is detected the Other is not. It also give a error called designed dragnonacally something...
When trying to compile my newly created ClassLibrary class 'Validator' that validates entries made into TextBoxs or MaskedTextBoxs, I get the following error:
Warning 1 Namespace or type specified in the Imports 'System.Windows.Forms' 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. C:Users erryDocumentsVisual Studio 2008ProjectsMillerClassLibMillerClassLibValidator.vb 1 9 MillerClassLib.
Following is the first part of code in the class:
Imports
System.Windows.Forms Public Class Validator
[code]....
What can I do to resolve this problem? The classes in this class library will be used to validate forms data input in a number of varied projects.
This 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?)?
