1. I need to pull some data from a text file separated by a space and put it in a drop down, the first value is supposed to be the text and the second value (separated by a space) is the value of the selection. I think I need to use an array and a System.Net.WebClient. How do I approach this?
2. I want to display some data from a text file into a gridview, so using datagridview, but I want them to be able to enable and disable a checkbox in these rows (using a listview?)
is there anyway to retrieve and list all the attributes for an active directory user to be used for updating with using the following
de.properties.contains(propertyName)

I have been doing some research to determine an efficient and secure way to pass a document located on another server in the network to our web server and then on to the intranet user that requested it. While I have found plenty of ways to do this, I am not that experienced with this scenario as I have always just served documents stored locally on the web server and located nowhere else.
Our document server is shared in the domain and everyone has access to it and depending on their permissions, can access many files. I was thinking that I could possibly grab a file if I could pass the intranet users credentials but I don't know where to look to do that.
I was also thinking that maybe a webservice could do what I need but that just doesn't seem right to me because I am kinda guessing that there is already a .net library available that already handles something like this but am unsure as to what it is.
OK, so I've been trying to look into a webservice.I'm not really sure what is going on with them.I haven't been able to find anything that really explains what the purpose and reason for them are. I suppose maybe that is because they can serve many purposes?

First off I am fairly new to VB .net however I have had some success in my project so far. I am creating a simple envelope accounting program for personal use. So far I have some basic forms created and have my class defined and a few methods for calculating my balances as well as changing the property data I want to work with. I now want to take this property data and save it to an xml file that I can easily retrieve the data into another form and save for later.
Here is a screen shot of the form used to gather the property data for my class
Here's the class code:
Public Class EnvelopeSystem
#Region "Identification"
Private eUsername As String = ""
Public Property Username() As String

I am looking for advice on how to get this to xml the most efficient way possible. Also if there are any blatant errors or easier ways to code what I already have I am still very new at this and would be glad to see easier more efficient ways of coding.
I am using vb.net and sql server 2005 as backend. I have a search form in which a field called billno is searched and all details are displayed in datagridview but the problem is I have to restart the project every now and then. Whenever any entry is done in database the immediate form opens is the search form so it must display the data which was inserted immediately without restarting the project.
For inserting data I am using the following code:
if TextBox1.Text = "" Or TextBox2.Text = "" Or TextBox3.Text = "" Or TextBox7.Text = "" Or TextBox11.Text = "" Or TextBox12.Text = "" Or TextBox13.Text = "" Or DateTimePicker1.Text = "" Then ErrorProvider1.SetError(TextBox1, "Enter Proper Details")

On data retrieval, it comes out as number instead of text. Im guessing ASCII?Why is it doing this? Do I need to convert each ASCII number into a character?
I'm opening this discussion up primarily because I felt that it was inappropriate that Samir Ibrahim and I had hijacked another thread by turning it into a collaborative development thread. This thread will also hopefully serve as a searchable reference for those few who actually make an attempt to search the forum for information before posting a question. For reference the original thread I mentioned is [URL]
This thread is meant to be a repository for our continued collaboration on trying to find a way to update the attachment field using the OLEDB class. Samir believes that he is close to cracking the secret code.:)
Attachment retrieval and updating is a fairly trivial task using the Microsoft Access Database Engine. It is also fairly trival to retrieve the attached files using OLEDb as well. The difficulty comes when trying to add or delete an attachment with OLEDB.
The attachment field is actually a record set where each record consists of six fields. One of these fields is the data field that contains the binary file data. According to the documentation, Access will compress certain file. It appears that compression/decompression is handled behind the scenes so to say and what you are present with is sequence of bytes. The data field consists of sequence of header bytes followed by the actual data. The first four bytes define an offset to the start of the data. One thing that we are trying to determine is the meaning of other bytes in the header.
I have uploaded a sample project at: [URL]
This project is by no means a finished product. It is hard code to retrieve the first record from the included Access database.
Is it good practice to store sub-collections of item X inside a parent collection of item X for caching 'filter-queries' which are performed on the parent collection? (They won't be used together (as in color AND type).) Or is it also ok to just Loop over the collection and return the correct entities in a temporary collection?

The Where clause cannot search the p.Services and p.Keywords EntityCollections in that way.

I've been working with a CMS called InsiteCreations 2008. I'm running into an error I just can't wrap my head around. I would even be willing to compensate anyone a small amount over paypal, for a solution. The error is rare in occurance, and appears when clicking about 3-4% of links to other pages within our CMS.The full code page is quite large, but there seems to be only one function associated with the error. The error also only appears when not logged into the CMS. If logged into the CMS, clicking the link simply displays the page as normal. I have already checked permissions on the page from the CMS admin console, and it is public.
The error message is as follows:
Server Error in '/' Application.Collection index must be in the range 1 to the size of the collection.
Description:
An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.

I need to convert a VB Collection to a modern one, like Dictionary or Hashtable. For my approach, I need the Collection's KEYS. Googling tells me that it's impossible. Re-writing the entire application using new collections is not an option as the application is really old and large (converted from VB6 to VB.Net).Using the old Collection also is not good - as there are new components in development.Converting a - for example - Hashtable to Collection works:
using VBCollection = Microsoft.VisualBasic.Collection;
