I'm getting an "Illegal characters in path" error. How can I fix this?
i am using the getfiles function to have all the files in a specific path but i want to use the getfiles to find .rar and .mp3 getfiles("c:program files",)
View 2 RepliesHow can I write this
Path = "C:"
For Each FoundFile In My.Computer.FileSystem.GetFiles(Path, FileIO.SearchOption.SearchTopLevelOnly, "FILE*.10") _
And For Each FoundFile In My.Computer.FileSystem.GetFiles(Path, FileIO.SearchOption.SearchTopLevelOnly, "FILE*.09")

Next My goal is simply to search for multiple file extensions. I cant use FILE* as my search parameter as this returns other files e.g FILE2012.10z which i don't want.
How can I filter on multiple file extensions when using IO.DirectoryInfo.GetFiles?
View 3 RepliesWhen 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?

What I would like to do is expand the filter to include alternative file extensions (i.e., ".rar", ".7z", etc)
I have certain files that need deleted every time I run my program. There are some files that start with f. and then end with .00000668 or .00005396 and so on. Here is my coding that is not working to delete the f files.

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'.
I'm using the FileSaveAs dialog control to allow the user to select a filename to save a file either as a doc file, an rtf file or a pdf file (that part was easy).However, after a bit of testing, it seems that the file extension doesn't automatically change when selecting the different file types.If the filename in the dialog is Foo.doc and I select FileType *.pdf and click "Save", my app still tries to save the file as a doc type.Virtually every other MS app automatically changes the extension to match a selected file type from the Office Suite to Paint. here's my code:
Dim dlg As New SaveFileDialog
dlg.InitialDirectory = m_sReportFolder
dlg.FileName = sProjectName & ".docx"[code]......
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?

For Each fi In folder.GetFiles("*.idx")
Dim reader As IO.StreamReader = fi.OpenText()
index = reader.ReadLine()
values = index.Split(",")

I'd like to inquire if it is possible to create a specific file extension like for example .wew and when the user double clicks over the that kind of file ,it excutes the programm associated with it ,and how can the contents be interpreted by the program, I tried to find how to do that ,and I only found soultion that deal with windows shell scripting

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.
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.
the problem is I'm trying to access a file that has no file extension. I think you can see why this is so difficult. The specific file I'm trying to edit is the hosts file (C:\Windows\System32\drivers\etc\hosts).
View 2 RepliesI get how to do it, and i have been to [URL] before. My question is about what doing that does, is it possible to reverse it? What if you do not know where your program will be, and you are just testing it for now? Is there any way for it to "find" your program, or an easy way to edit where it is opened? For that matter, is it possible to tell if the file has been associated already, is it an issue to try and reassociate? Finally, how can you set the .ico file it uses?
View 1 RepliesI am creating a program which can store files, and I display their names in a list box, with their contents in another list box.

View 1 RepliesI want to know how to create our own file, such as: (.Docx). If we opened the file in notepad the characters contained in the that's file could not understand, so i would like to know by what method of making the it's file? Is the file created and use encryption method or what?
View 7 RepliesInside the program I have a text box in which a user puts in the filepath to a textfile that the program then uses as a series of commands to perform tasks. This works perfectly, however what I would like to to do to make my program faster is associate the file extension .gam with the program, so when a user clicks a .gam file it opens the program and automatically sets said file's location into the text field, as opposed to using the browse button I added and browsing to said file everytime they run the program.
Through this a user could then make a shortcut to said .gam file and run it right from their desktop, as opposed to rummaging around in folders and whatnot. At the moment my method has been thus, I have 2 folders of importance I have archived with the .exe, Gambits Pro.exe, these are: Gambits, and Control, inside of the Gambits folder is the default storage location for .gam files, as when you click the browse button its default directory is that folder. I have also added a few example files in said folder for a user when they download the program.

Instead of creating a listbox to hold the names of one's favorites, I've made it so when you add a bookmark it adds it under the directory (yourusername)/bookmarks. (yourusername) is represented by login.usernametextbox.text. Now I've added a filelistbox to the form and want it to display the contents of the bookmarks folder only without the file name extensions. Just the title. Then when a user clicks on the title it navigates to that specified file by opening a new instance of a browser form. Here's what I have so far:
Private Sub Bookmarks_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
bmarks.Path = Login.UsernameTextBox.Text + "ookmarks"

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 4 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 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'."
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?
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.
