.net - Unable To List File Or Directory Contents On ASP.NET Page Using Shared Drive?
Oct 27, 2011
In this question I'm using Visual Studio 2008. My code is quite simple, as it was used from a reference I grabbed off the web. I'm using ASP/VB.Net, IIS6.0 on a Windows Server 2003 box.I've looked at various sources online, and have not been able to piece together a proper result. The purpose of this is to list a slew of directories and their respective files, and allow the user to eventually manage that directory (such as open and delete files).
Here is my ASPX page:
<%@ Page Language="vb" AutoEventWireup="false" CodeBehind="DirectoryList.aspx.vb" Inherits="VCMReports.DirectoryList" %>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml" >
[code]....
When launching the page, the following error appears: 'V:Users' is not a valid virtual path. Description: An unhandled exception occurred during the execution of the current web request. review the stack trace for more information about the error and where it originated in the code. Exception Details: System.Web.HttpException: 'V:Users' is not a valid virtual path.
Things I have tried:
On the server, I have mapped out the drive and the directory.Permissions seem to be properly set, impersonate is correct.If I were to list a directory in the actual directory "C:InetpubDirectory", there is no failure.I do understand this is incomplete for the Directory listing portion, this will only list files (so this will need to be modified.I have attempted to create a Virtual Directory, and the application presented the same error. On my local development machine, I have the same path created - same error. How am I able to view the contents of a shared directory and it's files?

First off a short background of the project I am working on- I am developing a program that will be run off removable media (i.e. USB Flash drive). This will be a �virtual desktop� which you will be able to take with you and have the same �desktop� on any system. As we know drive letters can change with each host system the drive is plugged into, I need to be able to determine the path for the flash drive and access a specific folder ( i.e. My Documents)
I have an picture box(representing the icon) placed on my form (form1) and when I click the icon I want to be able to open and view the a specific folder from the portable drive. I need a click event that will determine a dynamic drive letter for a directory on the removable drive and then open that directory in an explorer window.

We have a shared drive which has a folder in which we programatically store the reports we create in MS Access. Sometimes the user will lose the rights to insert the files in (write access) to that folder. But we are not shown any system generated error messages for this while adiing the reports. At a lter point of time we will come to know that those reports were not saved.I am looking for a code to check whether we have the write access to the particular folder and if not, throw a suitable error message.

I got a file to copy using vb.net 2.0 from another server to a local folder:
dim source as string = "\servernameshared directoryindex.htm"
dim destination as string = "D:/local folder/index.htm"
system.io.file.copy(source, destination, true)

I have a Motor Class, along with a Collection to hold objects address. Each Collection object holds the Class fields as a String to display in list box. I am able to write the collection string to the file and save the string. But unable to open the existing file, read the file back into the collection object.
Public Class Motor
Private strId As String
Private strDescription As String

I have looked all over for anything (samples or tutorials for working with files and collection objects) pertaining to type of operation with out any success.

I am unable to run batch file that is located in mapped network drive using System.Diagnostics.Process in VB.Net. I get:'<batchfilename>.bat' is not recognized as an internal or external command, operable program or batch file.Press any key to continue..I get the same error when navigate to the folder (using explorer) that contains this batch file and double click it. I can successfully run the batch file by changing the directory to that folder through command prompt. I can't figure out why this is happening. I think the problem is Start() function of Process works like double click rather than just run the batch file.

I am a Real Estate appraiser and have some limited experience with vb and .net. I have a task which I perform which requires me to go to the conuty appraisers web site and print a copy (to image bmp or jpg or directly to the default printer) of the current public record info for anywhere from a few pages to 1,000 plus records at a time.
I don't really get paid to do this part of the job so they don't care whether it takes me a few minutes or several hours to do this. I thought there must be a way to automate this process, so last week I started searching and test code snippets.What I have to date opens an instance of IE; navigates to the reguested page; finds the form elemet for AcctNo; fills it in and submits the form. The page that comes back is formatted for screen presentation and is not suitable to be sent to the printer. There is however a link which when clicked returns a page formatted for pinting. Downside is it also brings up the print dialog which then has to be handled. I was able through several methods to click either the print button or the cancel button which leaves me with a document that is either sent to printer or sitting on screen.
The questions are: Is there a way to do this without displaying the Print Dialog? Maybe a HTTPRequest or HTTPWebREquest as I have no need to see the screens just need the final page.The resultant page is typically longer then letter by a few lines and wants to print on two pages. It would be nice to resize the page to fit and typically it will be the same resizing. If I stick with the print dialog either clicking print or cancel how can I intercept the document and decide by options set in the program wheter to send the file to the printer or save to image?

I know, looping through is fast enough. But the search program "Everything" can index my entire C: drive in about 15 seconds. Does it read the MFT or something? Can I do this easily enough with VB.NET? Or at all?

I have a straight-forward task I'm attempting to accomplish. I have the mechanics down, and need to hammer out the details but I'm stumbling across one small point. :)
This script is supposed to take the files in the local C:Temp directory, and copy them to a selected user's shared directory on the file server.
Protected Sub btnCopy_Click(ByVal sender As Object, ByVal e As EventArgs) Handles btnCopy.Click
My.Computer.FileSystem.CopyDirectory("C:Temp", "\MAVERICKVOL1Users" & ddlName.SelectedValue & "DESKTOPRECORDINGS", True)
End Sub
This script does indeed work (and I'm aware I need to create exception handling) but it only copies what contents are on the server's directory of C:Temp rather than the local source directory.
I'm using VB.NET/ASP.NET to achieve this.
How am I able to direct my function to use the local user's directory rather than the remote server?

I am developing a website in ASP.Net and VB.Net to allow users to upload and download files from and to an FTP site and my desktop.
I have successfuly got the upload side working.
As far as the download part is concerned, I have so far got it so that when the user goes to the download page, the FTP file list appears so you can see the files that are currently residing on the FTP site.
I was wondering if there is a way that I can program my site so that the user can select one of the files and click on the 'Download' button that I have?
Here is my code so far:

I understand I've been asking alot of similar questions around this topic, but I think, with luck, and your help, this will be the last time.

What I want the program to do is to overwrite a pre existing file with all these values,
that is, essentially, to do the reverse of this piece of [code]...

I am trying to create a code where I placed sets of numbers in an array.I'll use a masktextbox to have the user enter the numbers to match what's in the array. If the user enters the number, ex: social, and the data is correct (matches the numbers in the array), something happens if the number entered in the masktextbox does not match any of the number sets in an array then another thing happens.The masktextbox so far only validates format and gets number only, however, I want the number entered to match whats in the array.

I am trying to copy the entire drive contents of a CF card to another location. For example:
Source Location:
e:DCIM
Destination Location:
X:2010-06-01
What I want to do:
- Copy E:*.* to Destination
- The original file structure can stay the same. I want to copy everything from the root of the Source Drive
I can copy the contents if I set source string to e:DCIM.. But I'm concerned that if I get something that doesn't have the first directory (DCIM) it's going to error.

A form that will display the contents of a folder? I have my forms set up, I want the user to then click on a button that will load up a nw form which will contain a window that is a folder in one of my drives. There may be folders inside this main folder which the user can go into, but they can't go back frrom the original main folder and look at the other contents. First up, Is an explorer form the one I am looking for? Making one of those, it seems to be the right path but where to from there?
Another thing I need to be able to do is have the user double click on the files inside of the folder. When double clicked the folder still maintains its current state, as the files that will be clicked will do the work in the background. I have all the forms set up and linked together, I just need to know how to get this folder into a form..
