Let's say that you have a texbox labeled TexBox2 and you don't want it to be seen when the program runs because TextBox1 pulls information from TextBox2 and it shows up inside of TextBox1. How would you go about doing this?

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")

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 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.

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 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 need to count the number of files in a specific folder. The folder I need is in the directory path of ApplicationData. The only method I could think of to grab the path, is to combine it via a string, like this: vb.net

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(",")

Assuming I have a folder structure like:
[Code]...
This works fine, unless I have Windows Explorer open and I'm looking at the 'MySubFolder' directory. Then I get an IOException The directory is not empty. - clicking OK dismisses this and then the folder structure is not deleted. Any thoughts on how I can get this to perform correctly (i.e. delete), even when running this code while having the folder struture open in Windows Explorer?

I am writing a calculator app in VB Express 2008. I'm trying to get the app to accept numeric and operator input while ignoring all the alpha input. In other words taking input from the numeric keypad and the top of the keyboard and ignoring all the letters.
Here's the block of code I have so far:
Private Sub TextBox1_KeyDown(ByVal sender As System.Object, ByVal e As System.Windows.Forms.KeyEventArgs) Handles TextBox1.KeyDown
If (e.KeyCode >= Keys.D0 OrElse e.KeyCode >= Keys.NumPad0) And (e.KeyCode <= Keys.D9 OrElse e.KeyCode <= Keys.NumPad9) Then
Select Case e.KeyCode
[code]....
I can't get vb to recognize the above code it seems to skip right over it. BTW, is 'Keys.Crsel' the same as the caret '^' symbol?
