VS 2010 Getting A 505 File Unavailable Error?
Nov 16, 2011
so here's my code. I'm testing to see if a user exists on the server before I let them log in.
'Creates test file
Dim write As New StreamWriter("c:/test.ping")
write.Write("This is a test string used to log in a user.")
write.Close()
[Code]...
Dim mStream As Stream = mReq.GetRequestStream()Another strange thing: the streamwriter won't write to C:/test.ping. I changed it to E:/test.ping and it wrote (E is my Ext HDD) but I still got the same answer.I'm using Windows 7 Home Professional. On my old XP PC I got it to work but that was a while ago.

I'm trying to upload a file via FTP from my local computer to an FTP server, which is also on my local computer at the moment. I've got this sub I'm calling:
Public Sub UploadFTPFile(ByVal ftpservername, ByVal fullfilepath, ByVal filename, ByVal username, ByVal password)Dim clsRequest As System.Net.FtpWebRequest = _
DirectCast(System.Net.WebRequest.Create("ftp://" & ftpservername & "/" & filename), System.Net.FtpWebRequest)
clsRequest.Credentials = New System.Net.NetworkCredential(username, password)
clsRequest.Method = System.Net.WebRequestMethods.Ftp.UploadFile

I'm running an FTP Server using Golder FTP Server, which is freeware. I think it's setup correctly because connecting to the FTP Server using the exact same string as above using Windows Explorer works great.

I've just rebuilt my PC and have upgraded to visual web developer express 2010. I have imported my projects which use the charting control quite a bit. Unfortunately my projects are failing to run. In design view the control is now showing as "unknown server tag asp:chart". I can see the Chart control in the data tab in the toolbox but it is greyed out.

This is a bit of unusual problem that I'm experiencing, but recently one of the users of a production application started reporting errors in the system. These were traced to a 503 Service Unavailable error when making a call to a web service used by the application.
Now here's the odd part, only the one user is affected by this issue. Other users of the application have not reported any errors. When the user logged on to a different machine that worked for another user, they still received the error.

My application connects to several SQL Server instances (Using SMO and ADO.net), these connections are all closed properly (I'm using Using), one connection is a SqlDependency for table change notification.
Part of the application establishes an encapsulated VPN connection to a remote system, this causes all network resources to be unavailable, including the SQL instances.
What would be recommended method of handling this scenario? Where a networksql disconnect is frequent but predictable.
I'm using connection pooling so have no control over re-establishing a connection, if I attempt to open a connection (Which retrieves an available connection from the pool) it will fail as soon as I attempt to use it. (As pooled connections are not tested to save overhead).

Dim excel As New Microsoft.Office.Interop.Excel.Application()
Dim wb As Microsoft.Office.Interop.Excel.Workbook = excel.Workbooks.Open(txtFileLocations.Lines(w))
Dim ws As Microsoft.Office.Interop.Excel.Worksheet = TryCast(excel.ActiveSheet, Microsoft.Office.Interop.Excel.Worksheet)
when the program tries to opens an excel file, it always throws me an error "Office has detected a problem with this file. Editing may hard your computer" and my program crushes.......The problem appears on the SECOND line, on DIM wb...blahblah.. i went to the office and unclicked the "protected view" checkboxes.. but it still throws me those errors. my guess is that the office i have in the computer is not the same as the one that my program uses to open excel files (i mean, i loaded/imported some excel.dll files in the program so i guess that will be the one) But how do i make the program not care if the excel file is "potentially dangerous"?

I have some coding which edits my text file and saves two versions, the first version removes all multiple space with one space and saves it as a text file and the second replaces the spaces with a comma and saves it as a csv file. The problem I have is however later on when I run other code using the saved text and csv files, it looks like the processes are in use. I get the following error:
The process cannot access the file 'Path' because it is being used by another process.My actual coding:
Private OpenFileName As String = IO.Path.Combine(Application.StartupPath, "TextFile1.txt")
Private SaveFileName As String = IO.Path.Combine(Application.StartupPath, "TextFile2.txt")
Private SaveFileName2 As String = IO.Path.Combine(Application.StartupPath, "TextFile3.csv")

I am trying to run simple application (e.g. generated from template by VS.NET 2010) on IIS6. I changed it to run with .NET 4.0 (its application pool) and checked with regiis (this pool has 4.0). I also changed all possible httpHandlers (svc etc), to run with NET4.0. All possible rights are checked (i think so). Almost every request results in "Server Application Unavailable" (sometimes it is empty page with -2146232576 (0x80131700) value) and "...Please review this log entry to discover what caused this error to occur." but EventViewer and IIS Log are empty.

I have a class that needs to check for errors in the data contained in a object.The routines that will check for errors could be implemented in concrete interfaces of supertype IErrorCheck. That way error checks can be discrete and added or removed from the class that requests the error checks.Each IErrorCheck implementation would be programmed against the supertype IErrorCheck (Strategy).But it would be nice not to recompile when checks are added or removed.Is there an accepted procedure for abstracting the error checks all the way out of the program, such as to read the checks from a file?

I am in trouble with publishing my project that uses an embedded database file. I publish my project but when I try to install and run it, it gives me an error as "Unhandled excception occured in your application. Database.accdb file could not be found." I understand that the problem comes from the missing database file. But in the project I assign this file as "content" and I believe that it should copy the file to the required folder that way, right? I also tried to "compile the file" in project but if I make it, visual studio gives an error.
