How do I (i) sort the array of type FileInfo returned by the DirectoryInfo.GetFiles method by (file) CreationTime in descending order and (ii) once the array is sorted efficiently load it or convert into a Queue object (of type FileInfo) for subsequent processing. I thought of using the queue object as it handles things on a FIFO out basis and I'll be adding to the queue as new files arrive.
View 4 RepliesIf I want to bind the files of a folder to a gridview, I can just do this:
GridView1.DataSource = New DirectoryInfo("C:MyPix").GetFiles
GridView1.DataBind()
...And this asp.net
<asp:GridView ID="GridView1" runat="server">
[Code]...
...But if I want to bind it to a repeater in stead, I would think I could display the filename like this:
<asp:Repeater ID="Repeater1" runat="server">
<ItemTemplate><%#Container.DataItem("Name")%></ItemTemplate>
</asp:Repeater>
...But that gets me the error "No default member found for type 'FileInfo'."
I have a project where I am looping thru specific files in a directory using a For Each FileInfo in DirectoryInfo.GetFiles() statement. My question is if I overwrite the current FileInfo object, will it still retain the reference to the object even though the file is no longer the same?
Code Snippet:
For Each fi In folder.GetFiles("*.idx")
Dim reader As IO.StreamReader = fi.OpenText()
index = reader.ReadLine()
values = index.Split(",")

Dim o As New System.IO.DirectoryInfo(Application.StartupPath() + "p") Dim myfiles() As System.IO.FileInfo
myfiles = o.GetFiles("*.r**")i have such code. for example I got 4 files in tmp dir. it's called file.rar, file.r00, file.r01 and file.r02 ,the return Array always comes as follow file.r00, file.r01, file.r02 and last is file.rar. Now I want the result in order like first file.rar and next is 00 01 02 03...n etc how to make it ? anyway dont make .rar in last I want to make it in the first place.seems there is a Array.Sort but I dont know how to use it this way.

View 6 RepliesWhen I use the code Dim di As New IO.DirectoryInfo("C:")it works fine, but when i use a string variable named "infos" i.e.Dim di As New IO. DirectoryInfo(infos)which takes an input from user, it gives me an ArguementException "Illegal Characters in Path".I tried replacing the variable, checked its value in the msgbox which is fine, but the double quote is added directly when it executes the IO.DirectoryInfo line and throws an exception. (Check the attachment)I have also tried infos.Replace("""",String.Empty) to remove the possible double quote, but it still holds that double quote.And when I use the same variable "infos" with substring to get the Drive, it works fine
View 27 RepliesI'm making a timer program, that I want to be able to store "unlimited" timer profiles, that someone can load and use. Now I've created a form that you fill with data, which then gets saved to a .xml file in a pre-defined directory. I'm now working on some sort of code that will:
1. Search the directory for .xml files
2. Find any .xml files and convert names to strings
3. Store the strings in a dropdown menu, so that when one is chosen, it loads that profile.
I think I have 1 down:
System.IO.Directory.GetFiles("C:Simple Timer")
Dim di As DirectoryInfo
di = New DirectoryInfo("C:Simple Timer")
di.GetFiles("*.xml")
First I want to tell u all I am an absolute beginner at using VB.NET and other programming languages and am going to start learning VB.NET.What I am trying to accomplisch I couldn't find trough Google I am trying to make a Windows GUI based tool in VB.NET (2010) which deletes files by fileage with some other settings.I have a Form1 with:
TextBox1 - Where I have the output of a slectfolder button
TextBox2 - Where I want to input the File Extention (comma seperated)
DateTimePicker1 - Where the date can be set to delete files before that date
Checkbox3-5 - FileAttributes (Hidden, System and Read-Only)
CheckBox1 - Run in SafeMode (No delete takes place)
This is the delete script I made
For Each file As IO.FileInfo In New IO.DirectoryInfo("C:YourDirectory").GetFiles("*.txt")
If (Now - file.CreationTime).Days > 160 Then file.Delete()

How can you convert DirectoryInfo such as a GetDirectories into a string. I can run the following just fine.
For Each m In Movies
lbMovies.Items.Add(m)
Next
But I really want to store something like m.GetDirectories.ToString into a structure I've built.
I am populating a datagrid control using files in a specified path (DirectoryInfo).I would like to filter the files based on a user specified date range (start date & end date).

I used the GetFiles function in the following code:
frmConvert.ListBox20.DataSource = My.Computer.FileSystem.GetFiles("c: empparse")
I need to do the exact thing as above but into an Array and not using a ListBox.
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

View 2 RepliesIt 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?)?

If I have a folder with a bunch of ".htm" & ".html" files in it and I use
My.Computer.FileSystem.GetFiles(myFolder, FileIO.SearchOption.SearchTopLevelOnly, "*.html")it returns all the ".html" files, as expected. But if I useMy.Computer.FileSystem.GetFiles(myFolder, FileIO.SearchOption.SearchTopLevelOnly, "*.htm")it returns ".htm" & ".html" files, when I would expect it to return only the ".htm" files. Is this a bug?
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?
When you do GetFiles() you can specify a search pattern such as *.txt. How can I specify multiple patterns. For example, in windows search you do *.jpg;*.bmp;*.gif. I tried that but no luck and the msdn not work. Is this possible?
