Asp.net - Bind Repeater To DirectoryInfo.GetFiles?
Mar 23, 2009
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'."

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.

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(",")

I am trying to bind a dictionary to a repeater control. I have a dictionary object which is filled with the Key (as String) and values as (Class object). I receive Object reference error when I try to DirectCast() the e.Item.DataItem to a Key-Value pair of that dictionary used for binding repeater. If you check the second screenshot, the e.Item.DataItem value is "Nothing" because of which I am getting Object reference error. What is the reason that the value is e.Item.DataItem is coming as Nothing?
aspx.vb code behind:
Private Sub PopulateRepeaterValues()
Dim tGetAddItemDtlIn As New nsFWTypeAdm.Item.cdtGetAddItemDtlIn
Dim tGetAddItemDtlOut As nsFWTypeAdm.Item.cdtGetAddItemDtlOut
Dim objItemDL As nsFWIDataAdm.IItemDL

I am using a repeater to build a custom table. However, I can't figure out how to make the table show subtotal if the next rows tour does not match the previous rows.
Something similar to that.
row1 tour1
row2 tour 1
tour1 subtotal
[Code].....
but this shows all the data in the nested repeater not the ones that match the parentrepeater fields for example tour,theme,dep7 should match in the child repeater

I have a parent repeater with nested repeaters.My problem is I am trying to use 'Next' and 'Previous' buttons to rebind my repeater (rptTabContent) and thus the inner repeaters also, but when I try to manipulate the state of these links during the ItemCommand event they are overwritten by the bind.

I have a form called studentForm which has a studentCombobox, studentTextbox and a studentDatagridView
In the constructor of the studentForm I need to bind studentCombobox to the StudentbindingSource of the main form and to bind studentDataGridView to appropriate binding source in the mainForm.So that this datagrid view displays all the bookings for the studentID currently selected in studentComboBox
studentComboBox.DataSource = MainForm.StudentBindingSource
studentComboBox.DisplayMember = "StudentID"
studentDataGridView.DataSource = MainForm.StudentDataSet
studentDataGridView.DataMember = "Names "
This is the code I wrote in the constructor

When 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

I'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")

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). While search S/O, I found this post, but I am getting an error on DateComparer ("'DateComparer' is a type and cannot be used as an expression.")
Here is my code:
Dim dirInfo As New DirectoryInfo(strDirectoryPath)
Dim dStartDate As DateTime = "03/01/2011"
Dim dEndDate As DateTime = "6/30/2011"

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

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?)? Here's some code to show the issue:
Private Sub bgrLongProcess_DoWork(ByVal sender As System.Object, ByVal e As System.ComponentModel.DoWorkEventArgs) Handles bgrLongProcess.DoWork

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?
