Overriding "OnXXX" versus adding event handler
Okay, this has come up in the past but I haven't seen anything that I
would call a good, solid general rule.
The question applies more generally, but I'm going to ask in the context
of a Control. How does one decide whether to write an "override" method
to an event and when to simply add an event handler for that event?
For example, you can either write a new OnPaint override, or you can
register a delegate that the Control's base OnPaint method will execute.
My current thought is that when you are not inheriting from the base
class, you register a delegate (duh, since you obviously have no way to
override the method in that case), and when you are inheriting from the
base class, you override the method (the main reason here being that if
you're inheriting from the base class, you want your new functionality to
always work, rather than relying on your delegate remaining in the event
handler list).
In other words, override when you can, add an event handler if you can't.
Is it really as simple as that? Or are there other factors I should be
considering?
Many thanks in advance for the wisdom of those who have gone down this
road before me. :)

convert an object to string and back (in a culture independent fashion)
to store user preference in our application we have an 'hand written' XML
file. (as opposed to XmlSerializer written one, which crash sometimes, on
some user's computer, for some unknown reason.. but I'm digressing)
In this XML file I store object value, which I convert to string (when
writting) and from string (when reading) with a couple of simple function
which (should) do a reversible conversion (using TypeConverter) (functions
below).
Unfortunately, for some Enum, (namely System.Windows.Forms.Keys) I got a
culture dependent string, even though I specify CultureInfo.InvariantCulture
as an argument in my ConvertXXX method with the TypeConverter. Even using
'new CultureInfo("en")' do not fix this behavior.
Any tip on how to fix these function (below) so they provide a truly culture
independent reversible object=>string=>object mechanism?
===================================================
public static bool TryGetStringValue<T>(object val, out string ret)
{
if (val is string)
{
ret = (string)val;
return true;
}
TypeConverter tc = TypeDescriptor.GetConverter(typeof(T));
if (tc == null)
{
ret = val.ToString();
return false;
}
try
{
ret = tc.ConvertToString(null, CultureInfo.InvariantCulture, val);
return true;
}
catch (ArgumentException) { }
catch (NotSupportedException) { }
ret = val.ToString();
return false;
}
public static bool TryGetTValue<T>(object val, out T tval)

Windows Workflow - What basic tutorials? What's going on here?
I thought I was an experienced programmer but I'm looking at the beginning
WWF tutorial (Simple Expense Report) and I'm baffled. I feel like I don't
know how to even begin reading this. I thought this was supposed to be
interactive coding. Since when do we cut and paste into a project file? Is
this just a temporary Beta thing? Why this constant use of command prompts?
Also I have downloaded other samples onto my machine and none of them seem
to work correctly. In the OrderingStateMachine demo, I get the error
message: "The project file <C:\data\Visual Studio
2005\OrderingStateMachine\VB\OrderWorkFlows\OrderWorkFlows.vbproj cannot be
opened. The project type is not supported by this installation." ??????

Truly cross platform?
The thread bellow titled 'Determining if two paths are the same' brings to
mind some of the first 'things' I had heard way back when DotNet started. It
was going to be the panacea of cross platform development.
I am asking the question here of the group to find out if everyone (anyone)
thinks this has come (or is coming) to fruition.
I think that perhaps it has gone a long way towards making it simpler to
communicate between platforms but I am not sure if the framework itself has
actually made it to the cross platform development hall of fame just yet.
What do you folks think is the possibility of truly doing that? Looking at
the mono project and actually trying to use it in some productive manner has
showed me that this is far off. Just trying to get it working along with GDK
and Mono-develop on a fedora Core 6 system was an exercise in futility.
While I can understand what drives the open source community I honestly can't
understand what keeps it going when stuff is that hard. I can install VS.NET
2005 and be developing in an hour. Hello world in Mono-develop never came to
life. But, I digress and that is another rant for another message area.
So, what are your thoughts and ideas? Tag: Advanced WPF text Tag: 129483
Locking Desktop and Threading Issue
Hi, I have an application that displays forms on the users desktop,
what I am doing with it is having a SystemEvents
SessionSwitchEventHandler to capture the lock of the desktop, I would
like to kill the forms when this event is captured, that piece is
fine, but I would like to sleep the app until the
SessionSwitchReason.SessionUnlock happens then I can wake it again and
go the correct part of the code? Can I wake a sleeping thread, or
should I not sleep the thread at all, is there another way to get the
thread to sleep or hibernate and then wake up?

.Net Windows Service ...data access problem
Hi,
I am writing a .NET windows Service that will access the database every 10
minutes. When the service calls the function in the business services layer
which in turn calls the correponding function in data access layer, this DAL
function fails. The reason 'apparently' being that the it can not read the
connection string information and hence can not create the database
connection.
Please note that that I am using enterprise library. All the projects
representing business service layer, DAL, Model, Web UI and also the the
windows service project are all in the same solution.
Can anyone tell me what should I do to get around this problem.

Installation problem - MSDN Libs for VS2005
I'm trying to jury-rig an installation of MSDN for VS2005 from ISO disks.
The company I'm working for has an 'install drive' so I'm not sure of the
pedigree of these directories. Essentially, since I don't have a CD burner
at my disposal, I'm trying to run the installation directly from the ISO
images using Microsoft's Virtual CD-ROM Control Panel v2.0.1.1.
The problem is as follows: It doesn't matter if I run the setup on the
first MSDN disk or call MSDN installation directly from VS2005's setup
screen. Either way I get an error message saying: "Error 1311. Source file
not found. U:\_17693_RTL_x86_enu_NET_Framework_SDK_HxS.cab. Verify that the
file exists and that you can access it."
I should note that given the current mounting scheme, the 3 ISO images are
disks T, U, and V and presumably software on the T drive should be running.
So how could it know about the U drive in the first place and why didn't it
issue a standard Insert Disk prompt? (The file definitely exists and I can
even copy it.) Tag: Advanced WPF text Tag: 129468

It doesnt do it in my case, even though 'Application Should check for

The Interlocked on the Edge of Forever
I've got a quick question that's been bugging me for a long, long time:
Let's say I've got a member variable (in a heavily threaded app):
private int _firstTime = 0;
To make changes to this is easy enough:
InterlockedExchange(ref _firstTime, 1);
... or I can use the InterlockedCompareExchange:
int oldValue = InterlockedCompareExchange(ref _firstTime, 1, 0);
No problems here.
... but, if I just want to read the value, I CANNOT do:
int myValue = _firstTime;
or
if (_fistTime==0)
Doing these requires a memory barrier of some type (volatile variable,
monitor, etc) to have any degree of reliability.
Now, reading the value out using InterlockedCompareExchange always seemed a
bit silly to me. I don't want to always write:
int myValue = InterlockedCompareExchange(ref _firstTime, Int32.MinValue,
Int32.MinValue);
I've never found (although not for lack of looking):
int myValue = InterlockedRead(ref _firstTime);
Of the code that I write, reading the value, and branching based on it's
value, is much more common than writing to the value.
I have, in the past, used volitile variables for this - but I've stopped due
to the various issues regarding volatiles (non atomic reads & writes).
Is there a concensus on the best way to do this? It seems like all the
solutions are.... incomplete.
Essentially I'm looking for a volitile varaiable that is atomically read and
written. Unfortuantly, these don't exist in any language I've yet used.

How to tell which window becomes the foregroud window right away?
Hello,
I followed the MS instructions to subclass Windows using C#.net
(http://support.microsoft.com/kb/815775) as the follows. I then opened
several Excel files, and selected anyone of them as foreground window. I was
expecting to see windows message, saying WM_ACTIVATE, or something like that,
however, to my surprise, I saw NO windows message when I randomly selected
those Excel windows, (although I could see other window messages, e.g.,
WM_GETTEXT).
It was said that this was because "Subclassing this way only works for
windows in its own process, not in other applications." Then, is there a way
to make it work on other processes? Will automation will make the "other
application" in the same process of our application?
My goad is: Tell which (e.g. Excel) window becomes the active one AS SOON AS
a (e.g. Excel) window becomes active.
Thanks a lot.

DataSet fields not updating, no errors being generated
I am using a web service to update some database fields. I used the
dataset designer to define my datatable and tableadapter. I had it
automatically create the insert, update, and delete statements.
When I run the update method, all of the fields are updated except for
four datetime fields. Another attribute these fields have in common is
that they allow nulls. When the method runs, the values in the fields
are not overwritten, they are simply not changed.
Here is the code used for the updating:
PurchaseOrderTableAdapter dAdapter = new PurchaseOrderTableAdapter();
PoDataSet.PurchaseOrderDataTable ds =
dAdapter.GetDataByPoID(poID);
foreach (PoDataSet.PurchaseOrderRow dataRow1 in ds)
{
dataRow1["PONumber"] = poNumber;
dataRow1["ConfirmingTo"] = confirmingTo;
dataRow1["poDate"] = poDate;
dataRow1["ReqDate"] = reqDate;
dataRow1["CancelDate"] = cancelDate;
dataRow1["AllowBackOrder"] = allowBackOrder;
dataRow1["ShipTo"] = shipTo;
dataRow1["BillTo"] = billTo;
dataRow1["ShipVia"] = shipVia;
dataRow1["FOBPoint"] = fobPoint;
dataRow1["Terms"] = terms;
dataRow1["IsPlaced"] = isPlaced;
dataRow1["placeDate"] = datePlaced;
}
try
{
dAdapter.Update(ds);
}
catch (Exception e)
{
return 1 + e.Message;
}
return "0";
I am new to C# and .net in general. Any ideas as to why this method is
not updating the "placeDate", "poDate", "ReqDate", and "CancelDate"
fields? The variables used are defined as DateTime types. As I said,
there are no errors flagged during the process.
Your advice is greatly appreciated.

deadlock on a single Select not in a transaction
Hi,
We have a web application developped in asp.net (I think it's not relevant,
but well, it's so you know)... Yesterday, we received the following message
"Transaction (Process ID 69) was deadlocked on lock resources with another
process and has been chosen as the deadlock victim. Rerun the transaction. "
The thing is, the query was a simple select with inner joins between 3
tables (like select fields from table1 inner join table2... inner join
table3....). This command is not in a transaction, so the deadlock seems
impossible. And moreover, the deadlock occurs on the DataReader.Read() not
on the Command.ExecuteReader(...).
Can someone explain why the deadlock can have occured and what could be the
cause and solution to it? Can it be a bug in SQL Server or in the .net
framework (I really doubt about it)?

Now the problem is how can I capture the event "valuesReset" of an key

possible how can I know which key object inside the collection has

How to capture Item's event through an object of its collection in a external class?
There are two classes
1) Key - contains some public variables, one method "Reset" and one
event "valuesReset" which is raised by Reset method.
2) Keys - this class is collection of objects of class 'Key' and it is
inherited with ReadOnlyCollection(Of key).
I'm pasting the code here
Class key
Public Event valuesReset()
Public _name As String = ""
Public _title As Integer = 0
Public _strong As Integer = 0
Public _italic As Integer = 0
Public Function reset() As Boolean
_name = ""
_title = 0
_strong = 0
_italic = 0
RaiseEvent valuesReset()
End Function
End Class

Custom control loading order
Hi, I have a custom control which loads data, with some critera from a
property of the hosting UserControl.
I try to get the property value on BindingChanged in my custom control,
but, at that time, host UserControl is not completly loaded, so my
property is NULL.
I can't call a custom control's method from host UserControl. It would
'destroy' the automatic behaviour...
How can I know in my custome control that the host UserControl has
finished to load ?

why use .net?
Hi there,
We need to retrospectively justify our choice in using .NET framework for
developing our site. Our techie isnt here so we cant run it past him. Can
some kind, helpful person run their eye over it and tell me if I'm tellling
porkies, or if there is anything I should add?
Why should people choose .net (I think ours is 1.1)
Thanks
Gay
******************
We recognised that in order to meet our aims of producing a high quality and
consistent website, we had to ensure that our system was fast, robust and
able to deal with a high number of users.
We chose .NET framework so that we could meet these needs now, but also so
that we could best account for any future developments in a cost effective
manner. This has proved the case, in that with our Stage 2 developments we
will be implementing a forum system. Using .NET has meant that we can
integrate new modules with ease. With .NET's cross-platform
interconnectivity, we feel that we have chosen the best approach for
future-proofing. Tag: Advanced WPF text Tag: 129346
What can we do in C#.net with a given window handle?

Piped input contains Unicode preamble
I'm an old dog and I like old tricks, so I write a lot of utilities that
accept piped input.
e.g.
TYPE mydata.txt | MyApp
or
MyApp < mydata.txt
or
App1 | App2
Then read the input with System.Console.In
What I found though is that if the input file contains a Unicode preamble
(i.e. EF BB BF for UTF-8) the preamble appears in the data, which is
inconvenient.
I'm not real interested in _why_ this is the case, but I wonder what others
do to resolve this.
So far, because I'm only concerned with "ASCII" text, I simply ignore all
characters above 7F, but I'd like a more elegant solution.
One other thing I tried was rather than use
System.Console.In
I tried
new System.IO.StreamReader ( System.Console.OpenStandardInput , true )
which worked some times, but other times was missing the beginning of the
data (which I assume is due to buffering). Tag: Advanced WPF text Tag: 129343
"The underlying connection was closed: Could not establish trust relationship for the SSL/TLS secure channel"
Alright Googler Groupers!
I've searched high and low and tried everything I care to, so I'll see
what the masses can conclude! I'm making both UPS and PayPal calls and
both of them *occaisionally* throw this error. Please help!
The error I receive is :
"The underlying connection was closed: Could not establish trust
relationship for the SSL/TLS secure channel"
The inner exception is:
"The remote certificate is invalid according to the validation
procedure"
My web.config has:
<system.net>
<settings>
<servicePointManager checkCertificateName="false"
checkCertificateRevocationList="false"/>
</settings>
<connectionManagement>
<add address="*" maxconnection="12"/>
</connectionManagement>
</system.net>
My Global.asax has:
ServicePointManager.CertificatePolicy = new CertificatePolicy();
ServicePointManager.ServerCertificateValidationCallback = new
RemoteCertificateValidationCallback(ValidationCallBack);
My CertificationPolicy class looks like:
public bool CheckValidationResult(ServicePoint sp, X509Certificate
cert, WebRequest req, int problem)
{
return true;
}
And finally, my code is:
HttpRequestHandler http = new HttpRequestHandler(connectionURL);
string response = http.POST(stuffToPost); Tag: Advanced WPF text Tag: 129342
Custom app and Korean
I have an application written in .NET, running under Windows XP SP2 and
Windows Server 2003 with SQL Server 2000 as the backend. This app basically
indexes documents to allow keyword searching.
We now need to load and index Korean language documents, but I have
absolutely no idea what would be necessary to accomplish this.
First off, we do use a third party product to perform the indexing, and I
know that it supports Unicode.
Any pointers and assistance would be appreciated.

managed API equivilent to WNetAddConnection
Hi,
I'm wondering if there is a managed class/method that is equivilent to the
WNetAddConnection API. I am writing an app that is required to connect to
various network resources without knowing whether those resources are
connected before hand. I also need the functionality of being able to
provide profile/password information when attempting to access the network
resources. So far I haven't found anything that will work, but if anyone
knows a way, I would appreciate hearing about it. Thanks.

Network communication with Windows Services
Hello,
I am designing an system where Windows services (clients) are
distributed across a company LAN. The clients are written in Win32
since not all network machines may not have .NET Framework
installed. The clients connect to a central SQL database to report
relavent status information from the network machines. There is a
WinForms application that monitors and provides results of the
distributes clients to an operator. The application also allows the
operator to deploy the clients to the remote machines via Windows
Networking APIs, or externally using Active Directory and a supplied
Windows Installer Package that installs the Windows Service client out
to the network.
The target network(s) are Windows based using Active Directory. The
client machines are Windows 98 and above....however, we may limit the
requirements to only support Windows 2000 and above if necessary.
I was hoping some of you can provide your opinions on the following
questions:
1) Given the above design/architecture, do you think there are other
or better methods for implementing the system? ie, any other
technologies that would better suite the situation other than each
client directly connecting to SQL Server...
2) Please comment on the idea of using a web service (installed on the
database server) for clients to connect to provide status information?
3) Are there other or better technologies for distributing the Windows
Service clients outside of the ones mentioned above? Note, this
system will be used on a broad range of networks that may not have
specific technologies in production.
Thanks in advance for your input. Its always good to get other
opinions. Tag: Advanced WPF text Tag: 129332
