I am developing an application that reads from a network shared folder on a separate Windows Server. When the application attempts to read, I am receiving the error message "System.IO.IOException: The Device Is Not Ready". I have tried running the application as an Administrator, however I still receive the same error.The files in question do not appear to be in use by any other application.

We have an in-house developed VB.Net Windows Forms application that is losing users' individual connections to the SQL Server 2008 R2 database.The bolded message below is what appears.
A transport-level error has occurred when sending the request to the server. (provider: TCP Provider, error: 0 - An existing connection was forcibly closed by the remote host.)I have looked at many numerous articles both from Microsoft and others, but have been unable to pinpoint the issue.Sometimes it occurs when the user has been away from the open application for a long-time; others maybe less than 20 minutes.
I have a report ready to print document, however you will make it stop reading when the records end up, give it displays this error:
Index was out of range. It should be non-negative and less than the size of the collection.Parameter name: index
I've tried an index = 0 to no avail, I think that has to do with the End print. Because I cannot make it stop reading after all the records appear on the leaves.
Is there an error list in vs 2003? I can't remeber if there was and can't find it in the options... The TaskList window shows the errors but also messages like 'Visual Studio is ready to deploy XY' and it is distracting.

View 10 RepliesMy ISP's DNS server goes down all of a sudden sometimes. This is very annoying while surfing the internet. So, I'm trying to make an application which has the following characteristics :
Runs in system tray
Pings the server periodically
Notifies when the server becomes unreachable/active
Now, I know that the existing workarounds are to use OpenDNS or ping <IP Address> -t in command prompt. I don't want to use them... the reason being that the former gives much higher pings than my DNS & for the latter, I'll have to switch windows.
I 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?

I'm currently working on an VB.net application using Win forms and SQL Server Express 2008. One of the major functions of our program is to generate work orders for field engineers. These engineers typically work in a factory and have to walk around the factory to complete these work orders doing things such as recording pressures and voltages of certain equipment. Right now they are printing out the work orders and writing down these values then entering them into the computer when they get back from doing the work.
We would like them to have some sort of handheld device we could push their work orders out to that would allow them to enter values/complete work orders and then come back and sync up with our app. Something like an ipod touch or maybe a bit larger seems like a good kind of device. Not really sure what kind of device would work for this and what OS it should run. I'm guessing it will be easiest if I can get something that can run SQL server on it. Also, how would I implement something like this?
I am a ASP Classic Programmer, professionally for a little over a year, I have developed some rather nice sites, including the one in my signature (Still a work in progress).
I have been forced to use ASP.NET (VB) for a FileUpload control, as it offers a self controlled way of creating Thumbnails, without the use of 3rd party controls, which is great, as my hosting server does not allow for 3rd party installs on their servers.
So.
The code below is what I have so far for connecting to the database and displaying a record is the "cookie" exist on the users computer.
Unfortunantly, this is not working, and to be honest with you, their is not a whole lot of resources available to show how to do this correctly.
So I am stuck with a lot of post and hoping that someone can actually assist me with this and tell me what I am doing wrong and maybe correct my code.
I am getting an error about the "Connection is closed"
If you want to re-write my code, I prefer something simple and basic, as the only thing that I am doing to checking rather the user is logged in, and if so, display a record from the database. I am NOT in the need for the DataGrid, so please do not suggest it, as I am only needing to check this one thing.
I would like to also add, that I have successfully contect to my database with the FileUpload control and save file names of the images uploaded, so I know that my connection string is done properly> But, for some reason the "SELECT" statement is causing a HUGE issue. (It was easier to insert, than to select, I am not use to that)
CODE:
I have a VB2005 winforms application that will loads city data from my database table. This is to ensure that the user enters the correct city spelling, in order to receive an accurate quote. Currently, there are about 150K cities that are being loaded to the dropdown listbox on page load. It takes about 30-40 seconds for that page to load. My initial thought was to allow the user to select the state first. Then load the city values. But the user has the option of going back and requesting a quote for a different city / state.
