Support for Windows 2003 Enterprise
I am developing a component that will in some cases use
approximately 2-3GB (depends on content) of memory. Does
either version of the framework support the 3GB switch on
any supporting version of Windows 2003 Enterprise. We
are considering upgrading our Dell 2650 to 8GB RAM and
Windows 2003 Enterprise, but I don't know if that will
actually get us anything until 64-bit comes out (on
Opteron). We have tuned the component as much as possible
using a virtual object/byte array design that is about as
conservative as you can get with .NET (approx. 59.001
bits per 59 bits of data). Hardware is almost always
cheaper than development so we are investigating possible
hardware/software upgrades prior to using a disk-based
approach.
Any help is greatly appreciated,

Smart Device option does not appear in Visual Studio .NET
As I've read elsewhere, I do not have the icons/options to create a
Smart Device application in my freshly-installed (and repaired and
re-installed) copy of Visual Studio .NET 2003 Pro. I re-ran the setup
program, and it also does not contain an option to select Smart
Devices anywhere in the modules/options screen. I have installed the
language for Visual Basic .NET (leaving out C++ and C#) as well as
many of the other add-ons and from what I read, that should be enough
to perform development for my Axim X5 platform.
I also installed the .NET Compact Framework 1.0 SP 1 Redistributable,
and the Pocket PC 2003 SDK in the hopes that they would add something
I needed behind the scenes.
Can anyone suggest to me why this does not appear, and how to fix it? Tag: FW: Taste that correction update that came from the MS Tag: 58055
Converting absolute path to relative
Hi,
assume I have two paths referring to files on the same
logical volume, like "C:\Home\Dir1\file1.txt"
and "C:\Home\Dir2\file2.txt". How can I convert the
second absolute path to a relative path based on the
first one, like "..\Dir2\file2.txt"? I'm looking into the
System.IO.Path class but can't find an answer...

BUG Report. Please confirm.
Hi,
I'm previously haunted by a bug which is now in Knowledge Base Article
818587 (Fix: Regression in Dataset Serialization in Visual Studio .NET 1.1
when a datarow contains a rowError or a ColumnError Property) which can be
found at http://support.microsoft.com/default.aspx?scid=kb;en-us;818587.
Please note that this bug only shows itself if the Windows Form Application
is run on dotNetFramework 1.1 but does not shows itself if the same
application is forced to run on dotNetFramework 1.0
Now, I think I found another bug which produces the same error message as
the bug above and it also has something to do with the rowError or a
ColumnError property. Even worse, the bug exists in dotNetFramework 1.1 and
also dotNetFramework 1.0. The error message is,
System.InvalidOperationException: There is an error in XML document (x,
xxxx).
---> System.NullReferenceException: Object reference not set to an
instance of an object.
To reproduce the bug,
1. Create a Web service with a dummy method.
<WebMethod()> Public Function Dummy(ByVal ds As DataSet) As DataSet
Return ds
End Function
2. Create a Windows Application or a Console Application and add the service
that you created in step 1 as a Web Reference.
3. Type in or paste the following code,
Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As
System.EventArgs) Handles MyBase.Load
Dim ws As localhost.Service1
Dim ds As DataSet
Dim dt As DataTable
Dim row As DataRow
Dim i As Integer
' Create a new DataTable
dt = New DataTable
dt.TableName = "TestTable"
dt.Columns.Add("TestColumn1", GetType(String))
dt.Columns.Add("TestColumn2", GetType(Integer))
' Create a new DataSet and add the DataTable into it
ds = New DataSet
ds.DataSetName = "TestDataSet"
ds.Tables.Add(dt)
' Fill the DataTable with dummy values
For i = 0 To 10
row = dt.NewRow
row("TestColumn1") = "This is row " & i
row("TestColumn2") = i
dt.Rows.Add(row)
Next
' Set error message to the rows
For Each row In ds.Tables("TestTable").Rows
' Setting the RowError property below will cause and
' exception is thrown when calling ws.Dummy(ds.GetChanges).
row.RowError = "Row has not been updated to the server yet."
Next
' Send DataSet to the WebService
Try
ws = New localhost.Service1
ws.Dummy(ds.GetChanges)
Catch ex As Exception
Console.WriteLine(ex.Message)
End Try
ws.Dispose()
End Sub
Can anyone confirm this? Thanks a lot. Tag: FW: Taste that correction update that came from the MS Tag: 58043
SMTP Mail
Has anyone had any issues repeatedly sending SMTP e-mails from .Net?

sometimes get "Could not access 'CDO.Message' object" errors

Remoting & Terminal Server
We have two .NET desktop applications. The applications
communicate with eachother via .NET Remoting. Application
X marshals an object on a tcp channel. Application Y
connects to that object to communicate with X.
When we install those 2 applications on a Terminal Server
(Citrix), and we start 2 sessions, then the applications
work fine on the first session. X and Y can communicate
via .NET remoting.
On the second session, the 2 applications cannot
communicate. This is because the port that is used by the
tcp channel is already in use by the first session.
Is there a solution to this problem? So that various
desktop applications can communicate with eachother in one
session?
We finally want to have 2 desktop applications communicate
with each other on each session via .NET Remoting. Tag: FW: Taste that correction update that came from the MS Tag: 58030

System.Console.In.Peek() behavior?
Please take a look at the following (more or less
nonsense) program.
I am trying to understand the exact behavior of
System.Console.In.Peek().
Does it block when no input is available?
From the documentation I would expect it not to block but
instead return -1.
However the first call to Peek() below seems to block -
no dots are written to the console.
Strangely enough, if you enter a text followed by return,
and then let the first call of ReadLine() "eat" all this,
I would expect to be in the same situation as at program
start up. However, this second call does not block, but
immediately returns -1 (dots appear in the output).
Whats worse - even if I type something followed by
return, this input is never detected by the sequence of
Peek() calls in the second while loop - I never get out
of it.
Am I overlooking something, or is there a bug in the .NET
framework?
peek.cs:
========
using System;
using System.IO;
using System.Threading;
public class test {
public static void Main(System.String[] args)
{
Console.Write("Enter some text: ");
// first peek will block!!
while (Console.In.Peek() == -1){
// we never get here
Console.Write('.'); Thread.Sleep(500);
}
Console.WriteLine("Input 1 available:
+ "Console.ReadLine());
Console.Write("Enter some more text: ");
// second peek is non-blocking,
// but never detects input!!
while (Console.In.Peek() == -1){
// we never get out of this loop
Console.Write('.'); Thread.Sleep(500);
}
Console.WriteLine("Input 2 available: "
+ Console.ReadLine());
}
}
Typical cmd session:
=====================
C:\>csc -t:exe -nologo peek.cs
C:\>.\peek
Enter some text: lklklklkl
Input 1 available: lklklklkl
Enter some more text: .............^C
C:\>lklklklkl
'lklklklkl' is not recognized as an internal or external
command,
operable program or batch file.
No dots appear despite waiting to respond to the first
prompt.
Input typed while the dots stream out of the second loop
is not detected by the program, but first after the
program is killed (here using Control-C)

How do you use OleDBLiteral?
I am completely baffled by the OleDbLiteral enumeration.
How do you get from the enumerated values to the things that they
represent?
I can't see any calls or methods that do this. ToString just returns the
name of the enumerated value.
This must be a really stupid question but I can't find a single worked
example that uses this class. either through google or in the 2 ADO.NET
books that I have bought.
You need this information to generate safe SQL that will run against a
variety of back-ends.

On one machine we succeeded in getting to work; but after an unknown

.Net Compact Framework with Visual Studio 2002
Hi, I have Visual Studio 2002 Enterprise Architecture Edition. I was
wondering if anyone has any information on how I can develop applications

right now I have Visual Studio 2002. Is there anything I can do? (Other than
the obvious upgrade to 2003).

2002. Don't know if its true. And I've had a real tough time trying to
figure out what to install from where to make it work. So if someone can

Windows Server 3003 and No-Touch Deployment
We're using no-touch deployment with a particular application. We can serve
the application from a Windows 2000 Server machine with no problem. We're
not able to serve the application from a Windows 2003 Server. It appears
that the app's .config is not being transferred to the client when they try
to launch the application from the Win 2003 server.
The web.config file for the virtual directories includes entries in the
httpHandler section to allow .config files to be retrieved, and we've
deleted the .config entry from the App Mappings tab in the properties for
the virtual directories (which I think means our httpHandler mods are not
necessary). The virtual directory on the Win 2003 server allows anonymous
access. The machine.config files between the two servers in question are
identical with the exception of some database connection strings in the
appSettings section.
An examination of the IIS log files on the Win2003 server shows the last
entry for a no-touch deployment session to be a GET for the app.exe.config
file with a status 401. A FileLoadException is thrown on the client machine
when we try to run from the Win2003 server.
What other settings should we change on the Win2003 server?

Socket Receive Error
Hi,
I'm getting the strangest problem trying to receive from a socket. I'm
downloading a huge file. When I loop, receiving until I get no bytes back,
it works fine. But I wanted to update a progress bar during this process,
so I added a notification delegate and I call this each time through:
Dim Ret As Integer, Buffer(1023) As Byte
Do
Ret = theSocket.Receive(Buffer)
If Ret > 0 Then
If m_DownloadToFile Then
m_FileStream.Write(Buffer, 0, Ret)
Else
m_Data = m_Data + ASCII.GetString(Buffer, 0, Ret)
End If
m_TransferredBytes = m_TransferredBytes + Ret
'if we have a notification
If Not Notify Is Nothing Then
'notify
Call Notify(Ret) <------this causes the problem
End If
End If
Loop Until Ret = 0
But when I do this, I start losing bytes. If I don't call the Notify
delegate, the file is something like 36MB. But if I call it, I seem to lose
data, and the file only winds up at about 21MB. This is kind of hard to
debug, so before rolling up my sleeves, I was wondering if anyone with
socket experience could spot the problem right off. Any help much
appreciated. Thanks.
Cheers,

Catastrophic failure
I have written an ASP.NET web app in C# that is trying to connect to a
database using OleDb. I put code in a dll that uses another dll to create a
connection object (and open it if requested) to send back to the web app to
connect to the database.
I am getting the following error when I change anything in my web app and
recompile.
Catastrophic failure
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.
Exception Details: System.Data.OleDb.OleDbException: Catastrophic failure
Stack Trace:

System.Data.OleDb.OleDbConnection.CreateProviderError(Int32 hr)
System.Data.OleDb.OleDbConnection.CreateProvider(OleDbConnectionString
constr)
System.Data.OleDb.OleDbConnection.Open()
I reset IIS to clear the problem (the only way that I have found other than
rebooting), and it will then work just fine. But if I adjust my code (the
web app not either of the dlls) and recompile, it will throw the
Catastrophic failure when I access the page. My coworker thought that it
might be because I was using a static module to create the connection, so I
adjusted the dll to be non-static. That did not solve the problem.
Is there anyway to prevent this failure, and is there anyway to clear this
error without having to restart IIS? Tag: FW: Taste that correction update that came from the MS Tag: 57939
