Im using visual basic 2009, im trying to wrtite the contents of a text file to a list box, im using the following format technique
{0, -5}{1, -20}{2, -20}{3, -5}{4, -5}{5, -5}{6, -5}{7, -20}
i have used a similar format in vb6 where it worked, but in .net it doesnt get me anywhere, does anyone have experience of using string format in vb.net and can help me? =]
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.
I have a listbox containing x-many different values.
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'm working on an application (ASP.NET, Webforms) that generates a list of outputs based on a user input. I want to allow the user to save the contents of said list as text file, or possibly as other filetypes such as .csv.Can it be done client-side with Javascript?

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.
View 1 RepliesIn 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" >

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?
I have this Quiz software that lets you create online multiple choice quizzes which are great for studying (I am in grad school and I'm trying to use everything I can to learn). So the Quiz software is great but it only lets you input questions by hand, one by one. I took a look at the .xml file that the quiz program spits out and came up with the idea to try and make a converter so that I can import many questions at once. I was hoping to try and solve this limitation by doing the following:
Take a .doc that say a tutor gives us with a bunch of practice questions, and then take that into Crimson Editor, and then format it so the question is on line 1, the multiple choice answers are on lines 3,4,5, and 6, (for the next question, the question would be on line 11, and the answers on lines 13, 14, 15, and 16, and so on) and then take that saved .txt file into my program, hit the generate button, and it will spit out the .xml file, and then import that into the quiz software to generate the online quiz.

I'm trying to read the contents of a text file. Everyone says it's a piece of cake, but I still get error "404 Not Found" even though the site exists.
I'm using the following:
Dim myRequest As HttpWebRequest
Dim myResponse As HttpWebResponse
myRequest = HttpWebRequest.Create("[URL]") 'This does work
myRequest = HttpWebRequest.Create("[URL]") 'This does not
myRequest.Proxy = New WebProxy("http://proxy address", True)
myRequest.Method = "GET"
myResponse = DirectCast(myRequest.GetResponse(), HttpWebResponse)
When I hit the [URL] the myRequest.GetResponse command passes the contents of the site into myResponse. However, hitting the [URL] always returns 404 even though it exists.
I have used Mid,InStr and other methods to get a substring of a string from one text file and copied the required string to another text file. While I get the correct string, vbscript however generates a BLANK SPACE after evry character in the output string.
I tried to use the Replace function inorder to replace the " " with ""... but the function does not detect any blank spaces at all to replace.
Instead of copying to another file, I even tried to replace the undesired part of the string with a " " and get only the required part ... but then again it gives the same problem[ a BLANK SPACE after evry character]

View 3 RepliesI'm wondering whether anyone else has had to do this. I've looked in to some third party solutions.
The two I've used with the most success are: 1. xPDF. This includes an executable, PDF2TEXT.exe, which takes an argument that is the path to the PDF file to "read" and a second argument which is the name of the text file where it will write the output. This works well and fairly quickly, but it's external to my application and calling it via a Process.Start() command raises security considerations and requires to user to allow the external executable to run. They must allow this to happen AT LEAST every time they run the import application (IF they will check the "Don't keep bothering me about this" box).
2. A solution from Foxit, which is GREAT, but costs a good bit of money to use. Does anyone have a solution that I can implement IN MY CODE (like #2) but that's free (like #1)?
