Convert List Of Directories To String?
Feb 10, 2010
I am trying to Add the name of every folder in a directory to a combobox as a string to use in other code. Then I would like to truncate the last 3 characters off of the folder names.Example:
My main directory is C:Main
My sub folders are C:MainsubOne_bp
C:MainsubTwo_bp
C:MainsubThree_bp
I want a combo box with the following added durring run time.
subOne
subTwo
subThree
The following code will get me the folder names in the combo box, BUT it will not truncate the _bp off of the end and they are added as IO.DirectoryInfo that cannot be used as a string in other tasks.
Dim dir As String = "C:Main"
If (System.IO.Directory.Exists(dir)) Then
Dim di_dir As New IO.DirectoryInfo(dir)
[code]....

I'm trying to solve a problem regarding types of list. First of all I have a stored procedure in my DB which does a select of a single column and I try to proceed it in my app in VB. By making a method function I declared a DataTable that loads through the SqlCommand(with the CloseConnection behavior). After that I publicly declared a List(Of String) which needs to be populated with the rows/items from the stored procedure that is on the way. Below is my snippet of the code:
Dim dt As New DataTable()
Try
If conn.State = ConnectionState.Open Then
[Code]....
It's LPrefix = collection.Cast(Of String)() where I get an exception error telling me that I can't really convert it. The old fashion way is to iterate with for/for each loop but that's not what I want for best use of performance especially if the list will have thousands of rows from a single column. So basically, I want to insert those items from that DataTable to the List(Of String) without For/For Each loop.
Running on VisualStudio2010 Ultimate, .NET FrameWork 4.0.

The intention is to convert an IList of custom objects to a string equivalent comprising each element in the Ilist. Unfortunately I can't seem to find a way to get the underlying data of the custom object, and of course as in the above example, using object simply gives me a string of types definitions, rather than access to the underlying data.

Normally, I'd choose List<String> [or, in VB, List(Of String)] over StringCollection whenever possible: see also Best string container.
However, as it seems, generics — and hence, List<String> — are apparently not supported in VS 2008's settings designer. Therefore, if I want to use a list of strings in my user settings, I have to resort to using a StringCollection there.
Now as I don't want to see StringCollection throughout my code, I need to convert it to List<String>. How do I do this efficiently? Or, even better, am I mistaken and there is a way to use List<String> in settings designer?

I am looking for a way to convert my List(Of string) into an Object in vb. So in the end it would be the same as declaring Dim cArray() As Object = new Object. Can anyone point me to how i can achieve this? I cannot use the LINQ .ToArray as that creates a string array and this is not acceptable for my work. I need to pass this object into another one that has the parameter (aArray as Object).

I want to convert a List (of Long) into a string array.
Reason: it's a list of database IDs and I want to make a comma delimited string to pass into a stored proc.I tried this:
Dim commaDelimitedList As String = String.Join(",", itemIDList.Cast(Of String)().ToArray)
but I'm clearly not using the Cast correctly since it throws an exception:
System.InvalidCastException: Unable to cast object of type 'System.Int64' to type 'System.String'..
Is there a way to get Cast working for this, or am I stuck with ConvertAll and a delegate function?

I'm using String.Join to attempt to turn an array list into a string that is comma separated, such as "1,2,3,4". I can't seem to get the syntax working.
Here's what I'm trying:
Dim aryTest As New ArrayList()
aryTest.Add("1")
aryTest.Add("2")
aryTest.Add("3")
[CODE]...
How can I go about doing this properly?

I'm trying to make a simple program to list a directory and sub directories on an ftp. I haven't found anything simple to do this other than a dll made for ftp commands. There are two problems with that dll, the first is I can't get recursing through directories to work right and it has a trial period. So I'm wondering if there is a simple pure VB way to simply list directories on an ftp. The dll I've played with is ChilkatDotNet2.dll.

'The string in the dictionary represents a jobname and the integer is a counter for how many jobs im currently are running in the application'
idCurrentJobs.Add("JobName1", 2)

How can I identify those directories that should be excluded from general use, such as $Recycle.bin, System Volume Information

I am trying to create a list of all virtual directories within an IIS site. However, I have found that trying to do this varies dramatically in the older versions of IIS. In IIS 7 this is a relatively easy task via C# but I can't seem to find a good method for doing this in IIS 6 and 5. I have tried using the System.DirectoryServices.DirectoryEntry but that doesn't seem to give me the desired output. I am the server administrator so I'm open to using other things such as .vbs files that are built into IIS as well as writing my own code.

IIS7 running on Windows Server 2008 R2. Development environment is VWDE 2010.
I'm setting up a simple "machine status" page to monitor a server. I want to display the Drives on the machine, including mapped network drives and show their free space, etc.
I'm using System.IO.DriveInfo.GetDrives() to return a collection of DriveInfo objects. I then itterate that collection to display the relevant information.
The issue I'm having is that only local drives appear. (A:, C: and D:) No mapped drives "Network Locations" appear in the collection.
I'm thinking it has to do with the user account that's executing the code (if that makes any sense). So if the code is executing under the user "ASPNET" (or whatever it is) the drives would have to be mapped under that user. As it happens, I have the server set up like a workstation and it logs in automatically under the user with the mapped drives.
What I've done:
- I have set the Web Site's Anonymous Authentication user to that same user
- I have set the Identity of the Application Pool to which my web site is assigned to be that same user.

im been messing with media player in my app. Great little feature Problem: I have a list of directories in an array. when a user double clicks a treenode in my treeview, i use this directory and add the correct extension to play the file. It works fine but when i click the 2nd node the media player plays the 1st movie again. My question is do i have to clear the media players memory (URL) in order to play my 2nd file?

The above code reads all the files & directories in a selected path. It ignores any hidden folders, like it suppose to. Except it doesn't ignore folders inside of the hidden folders that it finds & I need it to.I can't quite wrap my head around how to make it ignore all folders & files inside of a hidden folder that it find.
