Unable To Open File And Fill Collection With File Contents?
Apr 15, 2012
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
[Code]......
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.

My text file is something like what you see below, and I want to populate the datagrid. Once I populate the datagrid, I'll use that kind of like an excel spreadsheet in the sense that I'll dip in and grab values based on row and column index to display to the user. I will also (on a different form maybe) display the same datagrid to the users so they can sort by column at their choosing.[code]The error I am getting is: Value of type 'Integer' cannot be converted to 'System.Windows.Forms.DataGridViewCell'.

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?

I've posted this question in asp.net web forum but no one replied.
I can't open "ONE" page of .pdf file using IE8 and give me an error message "the file is damaged and could not be repaired" when retrieved from SQL Server 2008, but more than one page I can open with no problem.
With Chrome I can open any number of .pdf pages.
The same page that I can't open using IE8 from DB, can be opened directly from hard disk using IE8.
My code in .asxh file:
context.Response.ContentType = "application/pdf"
Dim strm As Stream = ShowNewsImage(imgName)
If Not strm Is Nothing Then

I am writing a program that acceses a file in VB/Visual Studio 2008 on Win7 and running it as a user who has admin credentials. I am opening the file with the following code:
Dim Input As New FileStream("C:FileTest est.txt", FileMode.Append, FileAccess.Write, FileShare.None) To test to make sure I can't access this file, I tried to open it with Notepad and I was able to and got no errors. I wrote a new value using Notepad and even saved it and I didn't get any errors form Notepad or my VB program.
I then went on and treid to open the same file twice from my VB program as:
Dim Input As New FileStream("C:FileTest est.txt", FileMode.Append, FileAccess.Write, FileShare.None)
Dim Input2 As New FileStream("C:FileTest est.txt", FileMode., FileAccess.Read, FileShare.None)
And I receivded an error in my VB program as expected. So the FileShare.None switch kind of works. Although I was still able to open the file with Notepad while my VB program had it open. I was aslo able to open Windows Explorer and reame it and even delte it while my VB program had it "open", in the write mode no less without my VB program knowing anything about it.
Why are other applications able to ignore the FileShare.None switch? Seems pretty useless if that's the case. And a huge secruity problem

I am working on a program with multiple collections related to one another for a school project. Each collection needs to have its own defined properties and have the objects written (1 per line) to a text file.
I have all of that working.
When reading the comma-separated line from the file, I want to place one of the properties of the object in a listbox (so that all the objects' names will show up in the listbox). I think I have this part figured out...
My problem is that when you click on the name in the listbox, I would like multiple text boxes to be populated with the appropriate, corresponding properties of the particular object in the collection...is there a way for this to be done?

I'm working on a homework assignment for class from the Programming in Visual Basics 2008 published by Mc Graw Hill. It is the Chapter 11 Case Study. We are to create a program that makes a text file and populates it with data. Then use a second program that reads the contents of the text file into form containers. The first half is working perfectly.

I have a dbf file. I saved it as a csv file and can open it in excel.
But i cannot open it in VB.net using programming and OLEDB connection.
If i copy all these content, paste it in a new excel sheet and then save it as csv file. My VB.net program reads it absolutely fine.
Any idea what might be wrong in saving the file directly from dbf to csv using excel?

Years ago when coding with VB6 and earlier, I used a file open command to create, read, and write a file that made it easy to store useful information.I believe it was binary and you wrote/read the data to a specific line in the file. When you opened the file with something like notepad, it just showed random ascii chars. When I needed a line of data, I could specify what line to load it from.

I've gone through about 16 hours and two packs of cigarettes trying to figure this out. First a little background. I was using 6.0 up until 2004 when I went to prison. I'm out now, and trying to relearn the trade, using VS 2005. I'm currently porting some 6.0 code from another project, SpyCast Webcam Studio, into VB 8.0. It's disheartening, to say the least. None of the old built-in subs/functions work anymore, so I have to scour the forums to relearn each and every function.The section I'm doing now takes a snapshot from the webcam (Video API --> PictureBox --> Save as Jpeg), then upens the file to upload it to the server via HTTP POST. I've been using this code in SpyCast for years with no trouble, but I spent many hours trying to piece together the right code to open the binary file to read its contents. I pieced together two methods I found around the forums, one using FileStream() though the code I found wasn't for binary files, even though it said it was, so that code doesn't really work. Method two uses Microsoft.VisualBasic.FileOpen() and works better.
Here's the kicker. By the time I run through the rest of the rigamarole of uploading the file, by the time I read it on the webserver, it's *slightly* corrupted. It's a valid Jpeg, no errors, but the picture looks like when I use to watch the Playboy Channel when I was a kid scrambled with weird colors and whatnot. [code] Each "chunk" is basically one "line" of the file. It looks like a single LineInput() return is the text between two carriage returns. Am I correct? I tested this with a flat text file, and it looks true. However, That one input line returns the text or data with the carriage returns *stripped*! ***?!? =( Fine, I have no problem adding my own vbCrLf to each LineInput(), if I were opening text. but this's binary. A character could be Chr(10) or Chr(13), both of which are removed from the original file contents.So I could very well need to use something other than LineInput(), but I haven't found any other examples on the web using this method.
