Thanks for the help.
<br />
Dim data As String = m_istream.ReadToEnd()<br />
'data' is null after the the call to ReadToEnd(),even though I can see data returned from this function in the debugger. This is the problem that has been plaguing me. It seems that I can't assign anything off the stream to a variable. I'm at a loss as to why.
The 'al' is an ArrayList, a very useful enumerated array type, the Adapter() method takes an IList object(string array in this case.) and converts it to an ArrayList. Just FYI.

for clarity, here is the exact code block:
<br />
Try<br />
m_istream = New StreamReader(m_ipath)<br />
m_al = m_al.Adapter(m_istream.ReadToEnd().Split("~"c))<br />
Return True<br />
Catch ex As Exception<br />
Return False<br />
Throw New Exception("Error Reading File! See InnerExcpetion.", ex)<br />
Finally<br />
m_istream.Close()<br />
End Try<br />

It would help if you explained what types were involved in the code. From what you posted, there's no way to tell that al was an ArrayList.
Well, you can try it like this then:
Dim data As String() = File.ReadAllText(m_ipath)
For Each s As String In data
Dim items As String() = s.Split("~"c)
al = al.Adapter(items)
Next

Sorry about that. I thought that I had, but I get ahead of myself sometimes. I should have realized that you knew what an arraylist was, I wasn't trying to be condesending. I'll give the File.ReadAllText a whirl.
Thanks again.

Is that method for 1.1 framework? I'm not seeing it.

it turns out that the while I was trying to watch the data in the debugger, the data was consumed, never to ne seen again, thus preventing anything I was attempting. I feel like such a dope. Anyways, thank you for the help Dave, and I apologize again for the comment.

I have developed a small database software in .Net 2.0 which has backend as Sql Server Express2005.Both of the server and client are running Windows XP. My client successfully detects the server but when
connecting to the server, it displays the error message "Cannot generate SSPI context".
I have also searched the internet but couldnot find any good solutions.
Could you people have any solution for this terrible error?
Help appreciated in both VB.Net and C#.

We'll have to see the code that generated this error. It would also help if you showed the connection string you're using to connect to the database.

Here is the code:
Server computer name is stored in My.Settings.Server property.
Public Shared Function RetCn() As SqlConnection
Dim sqlCnB As New SqlConnectionStringBuilder
sqlCnB.DataSource = My.Settings.Server & "\SQLEXPRESS"
sqlCnB.InitialCatalog = "CompA"
sqlCnB.IntegratedSecurity = True
sqlCnB.UserInstance = False
Dim sqlCn As New SqlConnection(sqlCnB.ConnectionString)
Return sqlCn
End Function

OK, this is .NET 3.0 because of the ConnectionStringBuilder class....
You cannot use Integrated Security if the two machines are not in a domain environment. If both of your machines are in workgroup mode, you MUST turn off Integrated Security and supply a username and password to get into the database.
Integrated Security uses the current users security token to login to the other machine. Since in workgroup mode, each machine maintains its own user database, the security token generated on one machine is not valid on the other.
Also, SQL Server uses two authenitcation mechanisms. Turning on Intergrated Security, or Trusted Connection, tells the connection string that the SQL Server is using Windows Integrated Security, instead of SQL Server Authentication. Using Windows Security means that the SQL Server will trust and use the machines user accounts (the machine the SQL Server is running on) for security ID's.

Hi guys,
Is there a way/control for previewing any document supported by the a windows system from vb.net?:->
thanks:->

Hi,
the Process.Start() method lets you open a document, using the application that got
associated to the file's extension. It is equivalent to double-clicking a file in
Windows Explorer; so al of this happens outside your app.
the WebBrowser class lets you open a number of document types (mtml, doc, ppt, xls, ...)
inside your app.

Hi,
The WebBrowser control is actually doing what I want, thanks. For PDF, picture formats etc its working fine i.e. it opens the file and displays it within the browser control, but when it comes to office documents, I get a File Download dialog box which then goes on to start the office application and open the document there or downloads the file to disk. Is there a way around this so that even office type documents are loaded but their applications are embedded within the WebBrowser control?
Thanks,

Hi,
Seems like yours is a web app, not a Windows app; I dont know for these.
I have been using shdocvw.dll (the precursor of WebBorwser) since .NET 1.1 in Win app,
and it shows office documents without dialogs.

If you're talking about how you see it in Explorer, where you single-click on a file, say a JPG, and you see a smalle preview in the Explorer window, then no there isn't.
You'd have to write a parser, and renderer, for every document type you want to support. That's just not feasible.

Hi Dave
Thanks for your response, however i think u should take a look at this link:
http://www.gamedev.net/community/forums/mod/journal/journal.asp?jn=266903&cmonth=11&cyear=2005
Its possible to have thumbnails, also using the WebControl allows u to open most documents effortlessly. Just:
WebControl1.Navigate("c:\book.pdf")
Thanks

Yeah, but for that to work, you have to have something installed that knows what a PDF is and how to render it, like Adobe Acrobat Reader. Without it, the web browser control doesn't know a damn thing about the PDF and can't render it. The same goes for Excel files, Word documents, AutoCad drawings, ...

You have compiled your project in Debug mode, not Release mode, yes?

Dear All,
I am using VB.Net 2003 and MS Access 2003. My project is running and time to time arise an error. Sometimes it appears as OutofMemory exception and other time as follows.
An unhandled exception of type 'System.StackOverflowException' occurred in system.windows.forms.dll
What can I do for this.

It means a function is calling itself until the stack is full, generally this means a recursive function that does not unwind, or an event is being fired by code that handles that event, so it gets fired over and over

Hi,
a typical bug leading to StackOverfloaException is having a setter property that
references itself rather than a class member with a similar name.
Warning: in VB identifiers are case-insensitive; in other languages (such as C, C++ and C#)
they are case-sensitive; so transfering some property code from say C# to VB is likely
to introduce the above mentioned bug.

Another possibility is if your doing any drawing on your form and not calling Dispose on your GDI objects when you're done with them.
Another is if you're showing forms with ShowDialog and not disposing of the form when your done with it.
... These things will eventually cause OutOfMemory exceptions.
