View 2 RepliesHow do I connect to a device through a USB port. Saying I know what the device ID is. I want to open up serialized communication between me and the device.
View 3 Repliesi'm kind of new to this. I'm using VB2008 and i need to write a code for recognizing a usb's details. like port number and letter and serial number if they have one. if i need to be more specific, then i have to say its for a machine that records data and i need to transfer that data over to my laptop through a gpib to usb cable. the cable has a specific "id" and i need to find that out and type it into the program interface that i'll make when i know how to detect that "id" so it can connect.i've read a few forum posts by others and they are really informative but not what i could use or i could not make it work.(yet)[URL]..and the other links posted there.for reading and helping. thats the clearest way i can explain. if anyone needs a more specific detail, just ask because i dont know if i left out anything else.

View 4 RepliesI am working on a way to send commands to an Arduino board from a web site. The Arduino board is connected to the computer via a USB port (a COM port).
I have managed to connect and control the board using a VB.NET program. I also wrote a VB.NET class that can instantiate a COM connection and send and receive messages.
My next step is to basically create a program that will act as a proxy between my web server (IIS 7 running on Windows Vista) and the Arduino board. When a user gets to my ASP.NET page, the page will then send a command to the proxy to open the COM connection. When the connection is open and ready then I can send commands to the proxy. In turn, the proxy will send these commands to the board and listen for the responses it receives from the board. The proxy will then pass these messages back to the ASP.NET page.
The main issue I see occurring is that if a second user opens the web page and tries to open the COM port, there will be an error. Will this cause the first connection to fail? I guess I can first check if the port is already in use and give the second user a message. Are there any other potential challenges I am missing or not seeing?

View 1 RepliesI 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..
I am looking at implementing a Web Service API for our product. I have figured out how you go about the general architecture/fault handling within WCF. My question is a more general one of how to design the overall error handling system. For example I have a method called SaveCompany (companyobject). Each company name needs to be unique. Say you tried to save a second company called "ABC Inc.". Would you expect to get back a fault named "DuplicateCompanyFault", or would you expect to get back an error code, or something else? I guess the root of my question is would you prefer to receive faults to handle, error code, or some combination? These services are going to be consumed by multiple different entities outside our company on multiple non-.NET platforms.

View 2 RepliesWe have two systems, one is created in VB.Net 2003 and the other is created in VB6. Both systems are client/server desktop application system. There is a requirement that we need to send and response data to each systems. The data will come as result of process of each system and then transfer it to the other system. These is formatted in a message format. Is it likely to become socket programming? how can I send and response data between servers?

I have been developing some components for our products at work, and one of them is based off the flow layout panel.What i would like to do is provide a custom designer for it, but without loosing the features provided by it's default designer (System.Windows.Forms.Design.FlowLayoutPanelDesigner) which is marked as internal.Using Reflector i thought i would just implement it again myself, seeing as it inherits from 'FlowPanelDesigner and that from PanelDesigner` all of which are internal.
Why would these classes be specifically marked as internal? Is it due to them being specifically for Visual Studio use, and thus not 'framework' code?Also, is there an easier option that re-implementing all the functionality?
