System.UnauthorizedAccessException was unhandled. I'm following motcom's tutorial on creating a simple directory explorer, and everytime I try to expand I get the error above. How can I be getting that error on my own computer ? I'm on my administrator account, it happens even if I compile it and run it as administrator also. What could be causuing this ?

View 2 RepliesMy application needs to change the default signature of outlook and I need to change the value of a registry key for this. But I get a error that I probaly don't have enough permissions. Strange thing is, if I change it manually it doesn't complain.
Error:System.UnauthorizedAccessException : Cannot write to the registry key.
Happens at the 2nd line:

the service is for now working correctly. Anyone have any ideas what would cause such an intermittent failing? I'm assured by co-workers that nothing was changed over the weekend (not manually at least). Baffled...
Ok so I have a small problem with an error I am catching. It only produces the file name and not the actual path of the file.I want to delete a folder and all the files and folders inside of it. However an error is thrown when a file is "read-only". A quick fix would be to set the attributes of that file to normal and then try again, the only problem is the error doesn't give you the location of the file.

View 1 RepliesI'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 get the directories like this:[code..]
However, it returns all directories even system hidden ones.It seems that this just follows what I set in Windows for file and folder browsing, since I set the Windows to show all files, I think it's also showing all folders to me, I am not sure however.
I just want NOT to get the system directories like Recycle Bin and System Volume Information, how to do that?
I'm running VB .NET 2005, and need to get the windows directory. I am aware of My.Computer.FileSystem.SpecialDirectories, but it doesn't have either the Windows directory or the Windows/System directory.

I have a textbox that is used to add directories to a system folder, each name seperated by a line. If the textbox has text value "Test " that is "Test" & controlchars.newline & "" (not like this is coded, it's typed in), then if i use loop for each part as string in textbox1.text.split(controlchars.newline), the first part will be "Test", the second part will say " " when i run step by step debugger, but if i try and block the addition of a folder by "if part = " "" it does not catch it. I've tried comparing part to "", " ", nothing (which is illogical anyways), and i even tried creating a boolean variable equal to the statment to try and catch it but the program insists that part is not " " even though the debugger tells me that is the value of part.

The above code reads all the files & directories in a selected path. It ignores any hidden folders, like it suppose to. Except it doesn't ignore folders inside of the hidden folders that it finds & I need it to.I can't quite wrap my head around how to make it ignore all folders & files inside of a hidden folder that it find.

it just creates 1 folder but not other folders with in folder.
I need to list all files folders, subfolders and subfolder files under a selected directory in a list box not sure how to do the logic in the last amount of code lines to enumerate all subfolders dna files.Here is what I have so far:

Basically I'm going to try and develop a software that merges PDFs automatically using the PDFSharp API.What I want in the program is to basically that: Have the program to give and Input and Output directoryMerge all the documents in the directory or sub-directoryRename the merged PDF file according the the name of the directory/sub-directoryIf the folder has PDF files and a Sub-Directory I want to merge the PDF files in the folder and rename them as per the main folder, and rename the files in the sub-folder according to its name (i.e. seperate|)
It's the first time I'm using an API.The problem I have is how to use the directories and sub-directories as I need them.

View 10 RepliesI 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:

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'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.
