I am trying to search a drive letter (C drive) for a file in Vb.Net 2010. After I find the file path I want to run the executable. This is the code I am trying to use to find the file:
path = Convert.ToString(IO.Directory.GetFiles("C:", "wswc.exe", System.IO.SearchOption.AllDirectories))

Is there any way to avoid UnauthorizedAccessException, i get it every time when I try to do this:
Code:My.Computer.Registry.ClassesRoot.OpenSubKey("Applications").CreateSubKey("Explorer.exe")
Is there any way to make that script read-write?
I'm using My.Computer.Filesystem.WriteAllBytes to write out an executable stored in my application's resources to it's startup directory. After running the executable, I then delete it. Everything works fine; however, I'll randomly get an UnauthorizedAccessException for no reason. After getting the exception, I can manually delete the file with no problem. Here's the full code:
' Convert MP3
' First, copy out converter
Dim Path = New IO.FileInfo(SoundPath)
[code]....
What perplexes me is that I literally just wrote out the executable, and nothing else could possibly be using it. I've checked the file attributes and it's not read-only. My application is also running as an administrator.
I knew that what I have doesn't create the username and password in the same .txt file. when i create a new user they both get thier own file with no text in them. When I tried to get the streamreader to access the previously created accounts, the only password acceptable is 'password'. I think it only accepts 'password' because 'Password.Read()' and it only created a .txt file Password when I typed it in. (I can't be for sure though). The top code is my Create User and the bottom code is my OK(accept created user).

I'm running windows 7 64 bit and using VS 2010. I'm trying to use the filesystem.getfiles to find a file on the computer and return the path for it. However, when I search C:/ and its subdirectories, it always throws an error: "A first chance exception of type 'System.UnauthorizedAccessException' occurred in mscorlib.dll"
I've looked everyone online and can't find a solution. I have administrator privileges and really I dont want people who use my app to have to adjust security settings for this to work. Is there not a way to search the C drive for a specific file and return its path? [Code]
I will have a directory of files (IFO, BUP, and VOB; DVD files for anyone who cares), I need to find the first one by sorting these like this: Filter out everything that does not have a .VOB in it, then find the one like this VTS_**_1.VOB. It will always have a "1" before the extension, but the two numbers before that change, lastly I need that file returned as a variable.
View 4 RepliesIs there a better way of finding the path of a file that was opened with the open file dialogue? This is what I did. It works, but it seems like there should be a way to get the path through one of the open dialogue options.

I need my published vb 2008 application to open a helpfile that I wrote. It is a simple .txt-file and this piece of code does the trick as long as the program is not published because I already know where I placed the Helpfile:
System.Windows.Forms.Help.ShowHelp(Me, "C:Helpfile.txt", HelpNavigator.TableOfContents)
After it is published on another pc, the helpfile is not on the root of the c-drive but in the application folder of the program. However, I can not know where the path to the program folder of someone else's pc is. It all depends on where they decide to place the program when they install, right?
It seems I need to replace this little: "C:Helpfile.txt" with some code that searches all the drives and directories and/or points directly to the Helpfile's placement - i.e. the parent directory of the program.
Dim filePath As String = "~/Images/FleaMarket/uploadedImages/" & User.Identity.Name.ToString & "/" & itemID & Path.GetExtension(fuImage.FileName)
MsgBox(filePath)

I've been doing a lot of coding latley and I'm interested in some things that vb can do. I was wondering if vb has the ability to search a directory for a file or mutipule files within a folder. Like in dos I can do C:user*.* and I can get all files that have . in them. Is there a similer way to do this in VB, I don't think VB has a wildcard or I've not heard that it does so I'm comfused on how I would find a file if I didn't know the path.

I'm using Visual Basic Professional 2010, I have two directories of XML files. The naming convention in directory one is a user's name, a six digit date and ending in ".xml_CREATE.xml". So, I perform some work on a file in directory two. During the course of that processing I discover that a file exists in directory one called "Mike" an unknown six digit date and ending with ".xml_CREATE.xml", so while I have no way to know the date, I know it exists and would look something like Mike030312.xml_CREATE.xml. So, now I want to load that file as an XElement that I will eventually incorporate into an XDocument, so I need to perform a Load similar to:
myXMLFile = XElement.Load(My.Settings.XMLDir & "" & Mike030312.xml_CREATE.xml),
However, since I don't know the date, I need to insert wildcards at that spot. How do I make that happen?
I am trying to figure out the numSamples in this:The canonical WAVE format starts with the RIFF header:

This works fine for getting the wave file info, It just doesn't display the numSamples which I need.
It seems like FileSystem.GetFiles() is unable to recover from the UnauthorizedAccessException exception that .Net triggers when trying to access an off-limit directory.In this case, does it mean this class/method isn't useful when scanning a whole drive and I should use some other solution (in which case: Which one?)?

I am working on a program that opens a .txt file, finds the length of each line in the file, and then outputs the minimum and maximum lengths. For example, assuming this is the .txt file I am opening:

27598493

I would like to return something like this:
Minimum length: 6
Maximum length: 9
I cannot use arrays for this assignment. I figured out how to get the maximum length but cannot figure out how to get the minimum. Am I going about this the right way or is there an easier way to do this? Here is what I have thus far:
