Stepping Through A Directory With Dir.getfiles(path,searchoption.alldirectories)?
Jan 2, 2012
When I have a directory setup with a subdirectory and both the top directory and sub directory have files in them I get a list of all the files with no directory info. That's OK, but I need to restore them to another location with the same directory structure in place. I'm essentially copying all files in a directory and it's subs to another location. The problem is the sub directory info is not in the files list so everything goes into the main directory. How do I get around this or can I? Here is what I'm using now.
I have a directory, NewProg in Program Files and a sub directory under it called Sub.
My.Computer.FileSystem.CopyFile("C:Program FilesNewProg" & File.Name, "C:NewProg" & File.Name,True)The Sub directory is not created and even when it is there, it always comes up empty with all it's files copied into the main NewProg.
im having some issues with getfiles, and i cant seem to pin point the cause, heres the issue:Im scanning a folder which has a mix of file types (.7z, .rar, .bin) and for each file im checking a dat file to see if that file (via the crc32) is listed in the dat. Pretty simple, but my code is randomly hit/missing heres what i have around my vb For Each strFile As String In System.IO.Directory.GetFiles(ComboBox1.Text, "*.*", SearchOption.AllDirectories)Next ComboBox1 .Text is a folder path for example 'C: est'
And inside of that i hae the crc32 code, the crc 32 code works great, the issue is with the above so no need to post lots of crc32 code. Now the problem im having is say i scan a folder with 10 files, lets say 5 7z's and 5 .bin's, sometimes the scan will scan all 10 files sometimes only 5 7z's and 1.bin, sometimes no .bins, sometimes only the .bins.If i put the .bins in a folder on there own and scan it will scan them all, same with the 7z's, so why is it not working when there all in the same folder?EDIT: I think the error is here 'SearchOption.AllDirectories' but i dont understand how to fix it, if i put all files into the root of the folder it will scan all of them, but i wanted to be able to scan the files in the subfolders to hence the SearchOption.All Directories, but it seem to be failing
I'm getting an access denied error when I run this code:
[code]...
If I change SearchOption.AllDirectories to SearchOption.TopDirectoryOnly then the code executes without any errors and the files in the top Directory are displayed. Apparently there is an access method that I need to set but I'm not sure how to implement it into the existing code.
I am having a problem with my application which I recently created. The application was designed to search for files either recursively or non recursively for files with certain attributes ie. file size, date created, etc. The application works (well sort of)....
I currently have the application creating a tmp file using IO.filestream and IO.FileMode.Create and then I'm using StreamWriter to write the names of all the files that are found with the matching attributes to the tmp file that was created in the tmp directory. What I have found is this:
If the parameter to do a search recursive is True then the names of the files through the directory tree are successfully written to the tmp file and all is well however if the base path specified does not contain any sub directories and searchoption.alldirectories is used I cannot get any of the files names who match the search criteria to be written to the temp file. If I add a console.writeline(sfile) just above the call to write to the temp file the names are written to the console successfuly (just like they should be to the temp file).
If I choose not to do a recursive search and specify using SearchOption.AllDirectories then I see a similar problem...none of the files in the top level directory that meet the search criteria are written to the tmp file like I'm telling them to. Again if I add a console.writeline just before the call to write to the temp file the names of all the files in the top level directory are written to the console successfully.
I cannot figure this one out...I am stepping through the code with the debugger and based on what I'm seeing I should not be having this problem. I know the logic is correct because I can write it out to the console correctly...
This is the code I have set up to scan a directory of files: Dim fileArray() As String fileArray = Directory.GetFiles(System.AppDomain.CurrentDomain.BaseDirectory & "help")
And it successfully gets all files in the directory, but it gets their absolute paths as well. For example, one of the entries in fileArray() is: F:ProjectProjectinx86Debughelpook_troubleshoot.html
And I want it to just be: book_troubleshoot.html Is there a way to do this without parsing through all the array entries to trim off the path?
I can't figure out how to use the (because im noob)ystem.io.directory.getfilesIf I try to put it in a textbox for example textbox1.text = system.io.directory.getfiles("my directory") then I just get the error message "Value type of '1-dimensional string of array' cannot be converted to 'string'. First of all I have no idea what the '1-dimensional string of array'thing is.And if I try to put in a msgbox for example sgbox(system.io.directory.getfiles("my directory")) then I can run the program but when I click my button then it says "it can not convert argument prompt to string(google translated)". And second, I don't know what the prompt thing is either
I am wondering if there is a simple method to filter the result returned by Directory.GetFiles(). Basically I am looking to retrive all of the jpg files in a selected folder into an array. My current code works fine if the folder only has jpgs in it which should be the case in operation but I would like to make sure it works correctly when the folder contains other types of files as well. The line I am currently using is..
Code:
files = Directory.GetFiles(IMAGE_DIRECTORY) files is defined as an array earlier in the program and as I mentioned my program works fine when the folder has nothing but jpegs within. The problem is that I am creating a listview with thumbnails from these files and run into some indexing issues when there are non jpgs in the target folder. The easiest solution would seem to be a filter on the getfiles method that would return only files witht he given extension.
Anyone know how to do this or will I need to parse the files out of the array in a second process?
I'm trying to load the most recent file from a directory, but my following code doesn't work. Am i getting something obvious terribly wrong?!
Dim myFile = Directory.GetFiles("C:UsersJoeDesktopXML Logs").OrderByDescending(Function(f) f.LastWriteTime).First()
I get two error messages:
Data type(s) of the type parameter(s) in extension method 'Public Function OrderByDescending(Of TKey)(keySelector As System.Func(Of String, TKey)) As System.Linq.IOrderedEnumerable(Of String)' defined in 'System.Linq.Enumerable' cannot be inferred from these arguments. Specifying the data type(s) explicitly might correct this error.
In the code below I got a UnauthorizedAccessException unhandled, access is denied to the directory 'c:WindowsSystem32LogFilesWMIRtBackup'.
A first chance exception of type 'System.UnauthorizedAccessException' occurred in mscorlib.dll.
How can I make the search only in allowed access directory's??? Dim searchResults As String() = Directory.GetFiles("c:", "*.idw", SearchOption.AllDirectories) For Each result As String In searchResults MessageBox.Show(result) Next
I have a directory 'C:Test' with three files in it:
A23456789.txt A1.txt G 5.txt
And I run this command:
Dim FileArr = Directory.GetFiles("C:Test", "*1.txt", SearchOption.AllDirectories)
All three files are returned.I understand that this is by design and .NET searches the 8.3 short file names as well.But is there any way to override this and search the actual file names only?Surely, in this day and age there must be a function to do this. Or do I have to write my own?I would like the search function to have the same behavior as the Windows Explorer for consistency.
I am using Directory.Getfiles(DirPath,"Pattern")to locate specific files in a folder. This works fine unless no files are found. How can I get my code to determine whether no files have been found?
I'm a developer for a College we have an active directory.I need to query Active Directory with the Pc name and return it's path in the Active Directory tree.
I've been testing the code below (vb 2010) and everything works except for the fact that I cannot get the statement "Dim dirName As String = Path.GetDirectoryName(Application.ExecutablePath)" to work. The dialog is "Path is not declared.it may be inaccessible due to protection level".As you may note I have it commented out below and went with the more explicit statement. Note that the code is from another author and I'd like to understand how to make this work as originally provided.

I've got a listbox showing events that have been added on my sports event planner, but how do I get the listbox to just show the directory name, not the entire path? [code]I found this code on the internet, and the 2nd msgbox displays exactly the information i need.how would i go about using that method with what i've already got.note that the 2nd code isn't written with arrays in mind, and the 1st is.[code]
I need a method to know iis current wwwroot in VB.Net.
I need to get this information outside a web project (otherwise the problem would have a simple solution). I think I need to read this information from the registry, but I have no idea where to start looking.
I want to get the last accessed directory path, what code should I use? The directory path I mean is just like when we use OpenFileDialog, default path of it is the last folder we accessed. I've tried to search but get no result.
I am using this code to have all the subdirectories in c:program files and i am listing them on a treeView Private Sub Button2_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button2.Click
I would like to log events to a .txt file. I think I have this covered for the most part. If I run my application in let's say /Program Files/App/ it will log events to log.txt within the /App directory. However, if I made a desktop shortcut of my app, it writes log.txt to the desktop. How do I set it so my path for my log.txt will always be within the same folder as the .exe and not where the application is run from (like with shortcuts)? how to I get the .exe directory to add it to the path of log.txt?
