Getfiles - Find Most Recent File In Directory?

Feb 20, 2012

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.

And:

'LastWriteTime' is not a member of 'String'.

Prevent Directory.GetFiles() From Searching Short File Names?

Jun 9, 2012

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.

System.io.directory.getfiles, How To Use It

Apr 6, 2011

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

Filtering Directory.GetFiles VB 2005?

Apr 27, 2009

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?

Directory.GetFiles Returning Entire Path - Only Want Filename?

Apr 26, 2010

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?

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.

files=dir.getfiles("C:Program FilesNewProg",searchoption.alldirectories)

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.

Why Does File.Exists Fail To Find 6 / 115 Files In Directory / When Same Process Just Downloaded All

Sep 5, 2011

I have a process serves as an application updater.It checks it's local cache of files and compares this against list of files online.On it's first run there are no files in the local cache and it therefore downloads ~100 of these files.[code]This appears to work very well, since Explorer confirms that all files are extracted and available.However when I later run this process again, it cannot verify the existence of 6 of these files and therefore tries to download them despite the fact that they are clearly both present and up to date.The offending code is a simple File.Exists call which appears to deny the local existence of these files, and therefore tries to get them again.The system continues to work well, but over time the continual downloading of these 6 files is going to get kind of silly.

How To Add Recent File History (Last 3) To Main Menu

Mar 11, 2011

How to add a file history to my Main Menu. I open my windows application and select a txt file to open called "File 1". Later I open "File 2" and "File 3". I have now closed the windows application. A day later I open my windows application again. How do I view the recent files selected to my FILE menu? For example, I would expect to see "File 1", "File 2", and "File 3" under recent files. This would allow the user to easily reference the past recent files that were opened. Word and Excel have the feature and I am sure it can be done in VS2005.

OpenFileDialog - Getting Specific File Type From My Computer Using The .getfiles Function

Jun 10, 2011

I'm doing a project now. I'm having a problem on getting specific file type from my computer using the .getfiles function.

Here's my codes.

Private Sub dlgOpen_FileOk(ByVal sender As System.Object, ByVal e As System.ComponentModel.CancelEventArgs) Handles dlgOpen.FileOk

Dim filepath as String = "C:"
dlgOpen.CheckFileExists = True

[CODE]...

What I wanted to happen is when the openfiledialog prompted and once I've selected the file, the file information I've specified above must show on the application as a label. But nothing appears. The file name only appears on the text box beside the open button. It should also appear above the button and the text box as a label. How could i possibly do that? And how could I select just one file at a time from a folder with 150 other files in it? When I use getFiles, it only gets all at the same time everything that's in the folder even if i've only just selected one file.
