How to parse string into DateTime?
I have a string containing a time and date string in the following format:
"HH:mm:ss MM/dd/YY" (example "14:34:12 12/31/02")
How do I parse this into a DateTime variable using C#?

Third-party help files not integrating with main .net help files
I have a third-party grid control that I am using. I installed it just
like I have done with other third-party controls that I have. Usually
after I install the control, and access help for the first time from
the IDE, I get a message saying that help is updating to reflect
recent changes, but I don't get it with this control so I cannot
access help for it. It is a .NET control and has all the correct help
files (not .CHM files). How can I force the controls help files to
intergate with .NET help?

Version nuber is not incrementing
I have default attribute in my assemblyinfo file:
<Assembly: AssemblyVersion("1.0.*")>
and I expected, that revision number should be incrementing as I rebuild an
assembly, because It shoul be a number of seconds from midnight divided by
2.
But I have the same assembly version regardless I made new build.
Why my assembly version automaticaly doesn't increments?

Console vs Service Application
I'm writing an application that needs to run every x minutes, read in some
data from a log file and then write it out to a database.
Originally I was going to write it as a service but the more I think about
it I feel it would work just as well as a console application that is
scheduled using the Windows scheduler.
I'm just curious as to whether there are any other advantages to using a
service that I might not have thought of?
Here are some reasons why I thought a console application would be
acceptable:
1. It is easier to schedule the console application using the Windows
scheduler or 3rd party scheduling applications, using a service I would
need to write scheduling code into it
2. It doesn't matter if the application is manually run between scheduled
periods
3. It could be handy to write output to the console so if someone manually
runs it that can see what is happening
Any thoughts would be greatly appreciated.

Empty columns when exporting to excel from crystal reports
Hi,
I tried this demo application in here (watch for any line breaks in the
URL):
(http://support.crystaldecisions.com/communityCS/FilesAndUpdates/vbnet_win_a
dodotnet.exe.asp
When exporting to Excel there is an empty column after each actual column in
the excel.
Why? Is this a normal behaviour? Is it impossible to get rid of the empty
columns when using the export funtion of the report?
Please clarify me so that I can decide to either use the export
functionality of the report or to implement my own excel export. I rather
use the export functionality of the report itself if I can get rid of the
empty columns.

Question: How do you retrieve Properties provided by an ExtenderProvider through reflection?
Hi,
I've written a simple ExtenderProvider that provides a string property
(Let's call it CustomStringProperty) to all the buttons on a form. The
ExtenderProvider itself is placed on a base form (It is protected, so
derived forms will inherit it's functionality) and provides the
CustomStringProperty to all forms derived from it.
It's canonical and works well. It allows the values to be assigned
during design time. Thereby easing the development of new forms and
insuring that all the buttons on new forms (that derive from the base
form containing the ExtenderProvider) have the CustomStringProperty.
Now I'm writing a small external tool that is attempting to extract
these CustomStringProperty(s) through reflection and log their value
in a database.
However, It's my understanding that the values of the
CustomStringProperties are assigned during the InitializeComponent()
method call of the associated forms (which to my knowledge doesn't get
executed during reflection). And I don't think that the properties
extended by the ExtenderProvider show up in the fieldinfo of the
buttons themselves, rather that you must go throught the
ExtenderProvider during runtime. Am I wrong?
Any advice would be welcome.
Thanks

efficient C# coding
I'm looking for a good article on efficient C# coding. All the DotNet
efficient coding articles I can find are oriented toward VB.NET, and while
some principals still apply, many do not. For instance there is no
equivalent of
with (some object)
.
end with
in C# (or somebody straighten me out).
Somehow in the my early studies of C# I got the (apparently wrong)
impression that it had some kind of great compiler that made all the good
practices I learned in VB unnecessary. Consider the following:
private static void LoadHeadings(UltraWebGrid Grid, XmlNode[]
PrevHeadingArray, SortedList FootnoteList, int CurRow)
{
for (int i = 0; i < PrevHeadingArray.Length; i++)
{
Grid.Rows[CurRow].Cells[i].Text =
PrevHeadingArray[i].Attributes["text"].Value
+
SuperFootnotes(PrevHeadingArray[i].SelectNodes("child::note"),
FootnoteList);
Grid.Rows[CurRow].Cells[i].Style.VerticalAlign =
VerticalAlign.Top;
}
}
I need to access the same cell twice, and I do it down a fairly long path.
Nowhere have I seen it advised to assign the object to a local variable and
then access it, yet when I did that the following code generated
considerably less code in the debugger disassembly:
private static void LoadHeadings(UltraWebGrid Grid, XmlNode[]
PrevHeadingArray, SortedList FootnoteList, int CurRow)
{
for (int i = 0; i < PrevHeadingArray.Length; i++)
{
UltraGridCell oCell = Grid.Rows[CurRow].Cells[i];
oCell.Text = PrevHeadingArray[i].Attributes["text"].Value
+
SuperFootnotes(PrevHeadingArray[i].SelectNodes("child::note"),
FootnoteList);
oCell.Style.VerticalAlign = VerticalAlign.Top;
}
}
I can't really interpret the assembler code, but I figure less code is
usually a good proxy for more efficient code.
Judging from my VB experience the next step would be to assign
"PrevHeadingArray.Length" to a local integer. Am I on the right track?
I really don't have the time to pursue these interesting investigations, and
I haven't taken the time to instrument the example above and see what the
comparative elapsed times are, I would much rather read this all spelled-out
somewhere. Tag: Installer Tag: 56877

Read from COM port?
I need to read messages from a device connected to a COM port with the
following format:
When the controller is configured to report events, it will transmit a new
message every time the event
occurs. The message follows the following format:
XX <Message> {CR} {LF} {Terminator}
. "XX" is the Message ID Number. Each type of report message from the
controller has a unique ID
number in a 2-digit hexadecimal format. Each digit will be a hexadecimal
value (numbers 0-9 or
letters A-F). When converted to decimal format, they represent the numbers 0
through 255. By
reading these two bytes, a user program can quickly identify the type of
message from the
controller.
. "<Message>" will contain a text description of the event.
. {CR} signifies that a carriage return is sent.
. {LF} signifies that a line feed is sent.
. {Terminator} signifies that a single-byte terminator code is sent. The
byte has a value 1d, which is
the ASCII code SOH (this is NOT the number 1, which is ASCII value 49d). The
terminator is
provided to make it easier for a computer program to read and interpret the
messages from the
controller.
What framework clases are best suited for reading this kind of messages from
the device? Can you specify the terminator character which is at the end of
each message?

ADO.net
Hey,
i am bit concerned about the architecture
provided in the .net frame work for ado.net.
The disconnected architecture does nor serves you best on
the desktop application. As you are not connected to
database and if any other changes the table in the
database you are not notified or your side data is still
older one.
As it was not in ADO we use to set the recordset
properties to our need and we were quite happy. but not
now.
Example:
Dim rs as ADODB.Recordset
TextBox1.databindings.add("Text",rs,"id") (X)
which is not allowed by the .net frame work, as i am
using the Recordset that is in ADO not in ADO.Net and its
required interface is not present.
But i want to do that ... as it is quite easy to
use this structure. I think there is problem with
Microsoft they dont even support there ADO properties in
their .net TextBox or any other control.
They should provide the Implementation of
connected recordset or simply implement the IList
interface or any other interface that is required for the
data binding in .net fram work.

TcpClient lost data timing anomaly
Hi
The platform: XP/pro on a dual Xeon 3GH processors
I am using TcpClient class to communicate with a POP3 server.
Short problem synopsis: a 'read' hangs even though there is data in the
buffer (as evidenced by a network sniffer trace).
Elaboration:
I/O is done by getting the NetworkStream and doing a read for a whole
buffer's worth (typically 1024) of bytes.
The code looks for the NL (new-line char, '\n'), as a delimiter. If found,
the text up to and including the NL is returned to the caller. Otherwise
another read is performed and concatenated to the previous read's output,
and the check for the delimiter repeats. On subsequent reads, if there was
data left over from the previous read, it is processed for NL before any
other reads are issued.
I have used a network sniffer to determine that all the data is coming in.
I have put a trace in my program to output to a file (serialized with a
'lock') all the output form all the read requests.
I consistently find that one of the reads is able to get all but the last 3
bytes of a response from a server. The code dutifully returns all the text
received and tries to do another read since the caller is looking for a
'.\r\n' sequence (end-of-message). This read hangs (I use the debugger).
When I change the buffer size the problem happens in a different message. If
I make the buffer large enough, the problem goes away.
The buffering code described above is working for thousands of messages that
have split across multiple buffers or for short messages where multiple fit
in the same buffer, so I'm pretty confident that it is splitting messages
correctly and gluing together segments across network messages.
My only conclusion is that something in the TcpClient (or deeper) is
checking the socket and waiting for more data in a non-atomic manner. The
problem shows up on my system because it is a fast dual processor system
that can obviously do concurrent processing by multiple threads/processes.
Has any one seen this kind of problem before?
Any work-around?

Problems with GCHandle and AppDomains
Greetings everyone.
I am currently working on a multimedia application written in unmanaged
code. As part on my next set of improvements, I would like to host the CLR
in the application and allow third parties to extend the application and
manipulate internal objects in the application through a "script" interop
layer I provide written (on my end) in managed C++.
The way my system is set up, from the default domain in my host, I
instantiate the script harness using AppDomain::CreateInstanceAndUnwrap
method and downcast the resulting object to a common interface that my
application and the harness know about. I call a "run" method on the
interface. In a test script I created, I register a callback object into
the multimedia app. The unmanaged callback object contains a GCHandle to a
delegate which it fires periodically on behalf of the unmanaged application
based on certain timing parameters.
Now, when the harness and my test script used to run in the default domain,
everything worked like a champ. Now that the test script is in a different
domain, when the unmanaged callback object dereferences the gchandle to
invoke the delegate on the script, I get an ArgumentException with a
description that reads: "Cannot pass a GCHandle across app domains". I've
hit my head against the wall trying to get this to work for a while now with
no success.
Does anyone have any idea what I could be doing wrong?
Thanks in advance for any help you can give.

Localization and multiple string resources
Hello!
I am looking at .Net localization. I happen to be using J# with VS
2003 but it could be any supported language.
The LocalizedHelloWorld example from MSDN and VS shows how to localize
a single .resources file. Here is a link to the J# version:
http://msdn.microsoft.com/library/default.asp?url=/library/en-us/dv_vjsample/html/vjsamlocalizedhelloworldsamplesatelliteassembliesforconsoleapplications.asp
The problem I have is I am working with an application that has
several string resources per DLL. I have not been able to find a way
to get it to work.
The example loads a resource called
"HelloWorld.Resources.MyResources". Each localized version is
embedded in a DLL called "HelloWorld.resources.DLL". The trick seems
to be that there can be only one such DLL.
I have modified this sample and tried embedding two resources,
MyResources.resources and MyResources2.resources, and also creating,
for example, two French resources, MyResources.fr.resources and
MyResources2.fr.resources, into the satellite assembly
"HelloWorld.resources.DLL". But, when I request
"HelloWorld.Resources.MyResources2" with the culture set to "fr", it
fails to find the second French resource and falls back to the
embedded MyResources2.resources.
Does anyone know a way to make this work?

Base Class Prop not hidden to Reflection
Hello,
I'm encountering an unexpected behavior when using
the "new" modifier in a derived class to hide an inherited
base class property. I use "new" intentionally so I can

I can use the derived class as expected through standard
instantiation. The unexpected behavior occurs when I try
to set gather the PropertyInfo for the derived class
property via Reflection. I get an AmbiguousMatchException
as both the base class and derived class property
implementations are found. Perhaps I don't fully
understand the "new" modifier - I expected the base class
member to be hidden completely when working with the

illustrates the behavior. If anyone could explain this, I
would be very interested in understanding. Thanks.

Any Container Managed Persistence ?
Hi,
I am considering shifting development from J2EE to DotNet. I was wondering
if there is any equivalent of container managed persistence in dot net
framework.
Also, are there any third party libraries that could be used for this
purpose ?
Thanks in advance,

delegates over remoting
i wondered if anyone could tell me why i get a security
exception when i pass a delegate to a "broadcasting"
object that takes a delegate as a parameter.
the "broadcasting" object takes a delegate and invokes
the method in a new thread. the idea was to pass a method
to another computer for it to excecute instead of me
please advise

Framework Versions 1.0 and 1.1
Hi All!
I have the .Net Framework 1.1 and the Visual Studio
2003 installed in my development machine. But I need to
develop an application in the framework 1.0. How can I do
this? Can I install the framework 1.0 in the same
machine? Do I need to install the visual studio 2002 as
well? Or do I need to unistall the framework 1.1 and the
Visual Studio before?
Thanks

locating netfx.msi
I have tried locating this file on both the original
Operating CD (Windows Pro 2000) and the upgrade CD (XP
Pro) but cannot find the dotnetframework folder or
dotnetfx.exe.
I have also tried installing Microsoft .NET Framework 1.1
to see if that fixed my problem.
Where else do I look for the file I need?
Please advise,
