Reading DLL.Config File Fails?
Oct 27, 2010
In out app we use dll that are loaded as addins. At startup we search the config files for these dlls in the application folder.The config files are named MyAddin.dll.config. On a win2003 R2 server running terminal services (in a domain with a SBS 2008) some of the users have problems reading the config files. I get an UnauthorizedAccessException when opening the config files like this:
Dim fs As New FileStream(strfile, FileMode.Open, FileAccess.Read)
reader = New System.Xml.XmlTextReader(fs)
fs.Close()
When I rename the files to MyAddin.config this works fine. Is the OS restricting the access to xxx.dll.config files?

I'm using vs2010 and can't get this to work. The same code has worked in earlier versions. What has changed?
config file:
<appSettings>
<add key="ConnectionString" value="Data Source=MikeLaptop;Initial Catalog=AdventureWorksDW2008R2;Integrated Security=True"/>
</appSettings>
Code:
Dim strProvider As String = ConfigurationManager.AppSettings("ConnectionString")
strProvider is always = nothing
How to do this now?

I am connecting to a data stream that pushes data continuously and when I tried to set up a network stream I just could not connect and kept getting the 'not found' error. I used the httpwebrequest with webrequest.keepalive = true and started to consume the data by reading into a buffer and then appending to a stringbuilder. Once the stringbuilder reaches max size I flush it to a text file. The problem is that I get disconnected from the data stream because I am not reading the data fast enough. I need to keep the connection open and read the data while ensuring data gets stored in text files. If I use method "CONNECT" it does not connect to the stream.
While (True)
webrequest = DirectCast(Net.WebRequest.Create(url), HttpWebRequest)
webrequest.Credentials = New System.Net.NetworkCredential(username, password)
webrequest.Method = "GET"
[code]....
should I increase the buffer size and if so what is the max? that would mean I can read more data at a time and keep up with incoming push. Disparate here.
ACtually also I noticed that it gets stuck on this line
numbytesread = responseStream.Read(bufferread, 0, BUFFER_SIZE)
and then eventually I get disconnected.

I have this method:
Private Sub SetIfNotNull(ByVal input As Object, ByRef destination As Object, ByVal ConversionType As ConversionType)
If input IsNot Nothing AndAlso input <> "" Then
Select Case ConversionType
Case DealerTrackConnection.ConversionType._String
destination = input
[Code] .....
And here is one call in which it fails:
SetIfNotNull(ApplicantElement.Element("suffix").Value, NewApplicant.Suffix, ConversionType._String)
If the element from the XML file is nothing (there is no tag), the method call fails. but I am checking for nothing.

I'm looking for a way to specify the location for the User.config file that is used for storing the My.Settings object. It appears that this is not possible. The problem for me is, I don't want to be responsible for creating several different files on the users computer that really have no use and are difficult to find and clean once an update is released. For most users, this is not a serious problem, as many will probably never update the software, and most will probably only go through a couple of updates. On my system, there are config files for every build of the application, and the same to a lesser extent will be true for my beta testers.
I can understand that MS wants to make sure that no two applications will use the same location for storing application data, but a simple [UserData] [CompanyName][ApplicationName] for storing application data will probably suffice for 99.9999 percent of the legitimate applications in the world. Bogging a user's system down with erroneous files, no matter how small, is an unnecessary drain on system resources and a potential source of problems for the user. It's bad enough that most programs leave bits and pieces of themselves all over a user's system after De-installation - this to me seems only to exaggerate this problem.
Is the only way to get around this problem to write a whole new Settings Class? Is there a way to change the location of the UserConfig file to a more friendly (and more predictable) location that I am not finding for myself? It would seem that having at least the OPTION to specify a location for the User.Config file would be OBVIOUS and easy to implement, so why did they leave this out?

I have just written an application in visual studio 2005, and would like to publish it for use on another computer. When I try to run the publisher, it fails and reports that it is missing an XML file that is located in the bin folder. I have checked the bin folder and the file is there. I am not sure what I am doing wrong? Has anyone else seen this type of error before?
Also, I should point out that while I was creating this app, I would some times copy the project to my desk top, and then change the name of the project folder. For example: myProgramV0 would be come myProgramV1. Then I would copy this back into where I normally keep my VB projects. I do not know if this had an effect on the program or not.

I have written a generic file serving handler in asp.net/vb.net..I recently moved to a windows 7 box and am now debugging under IIS7, and this is where the problems occure.Whenever I serve a file to either FireFox or Chrome (IE8 works fine) from IIS 7, the download will fail.
- In FireFox the error is "[some file name and path].part could not be saved, because the source file could not be read."
- In Chrome the error is "Error 330 (net::ERR_CONTENT_DECODING_FAILED): Unknown error."
- In IE8 it works fine
If I run the same code in IIS6, it works fine.If I run the same code in the Visual Studio virtual web server, it works fine (on windows 7 or XP).I am rather concerned about this as our production web server will soon be IIS7; which I'm starting to really love, and would hate to revert to IIS6 just because this won't work in IIS7.I've tried a number of different patterns.It seems to always fail on the Flush() line with the error "System. Web.HttpException = {"The remote host closed the connection. The error code is 0x8007 0040."}"One thing I have noticed, if I move the flush statment to the finally clause or remove it all together; firefox will attempt to read the entire file - it appears to be looping through the entire block of code just fine, until it hits the flush statement.If I remove the flush statment I still get an error and it still tries to read the entire file before asking me to save it.[code]

I have set up several tasks on a new installation of Windows 7 and they are working as expected.But when I attempted to run a batch file it fails. It works fine from the command line and I can run it from the scheduler on Windows XP manually (although not on the timer yet).What is about batch files that I need to know to make them run from the Task Scheduler?

I have this pretty simple application, it uses a webService to transfer data to my servers DataBase. Now it is very important for me to keep this application as one single file, and not having some XML files needed for it to work, but this is the case. I think the XML file holds the information to this webService, so without it the application crashes. Is there a way to get the application to work without this XML file, or a way to put the XML inside the exe archive?

I have a little vb.net script that will copy a file, set its attributes to Normal, update the file time, and then set back the attributes to match those of the source file.
If IO.File.Exists(Destination) Then IO.File.SetAttributes(Destination, IO.FileAttributes.Normal)
IO.File.Copy(Source, Destination, True)
IO.File.SetAttributes(Destination, IO.FileAttributes.Normal)
[code]....
I however I'm encountering a quite strange problem. On some configurations, IO.File.SetLastWriteTimeUtc triggers an UnauthorizedAccess error, although the IO.File.Copy instruction worked very well.

I have existing file named myapp.exe.config . What I would like to do is have a little app where user could specify path to app database. I know how to get file path but I dont know how to change existing line in myapp.exe.config file. No changes during runtime. Just simple app to change string in app.config file. I would like to enable user to select path to database and store that path in app.config file. Line which I would to change has a string "|DataDirectory|mydatabase.accdb" and i would like to change it with for ex. "C:Myappmydatabase.accdb" ( if it is selected file's path).

I've never thought about it before; but I recently learned how I could modify the app.config file to add/remove trace listeners (for example, to redirect all of the Trace.WriteLine output to a text file).But I don't quite understand how it works? I know the corresponding C# code to do the same as the config (in this example) - does that code get generated/executed before my application's entry point?

As a practice exercise at my college we have to make a simple room booking system, complete with its own config file. We're not allowed to use the one built into VB.NET (the professor wants us to adapt to not relying on things like that) so I've made my own. This is a sample:
// Config file.
// First column is the variable name that will be used to
// reference the value in the second column. Seperate each
