Center a HtmlElement in WebBrowser
I used the WebBrowser control in my C# application. The document
loaded in the WebBrowser is a long dynamically generated page. When
the user select something on the form, I would like to scroll the
document (animation is not required) to a corresponding HtmlElement in
the document, and I want the element is located vertically center in
the WebBrowser control.
I used the HtmlElement's Focus() method. It surely scrolls the
document and brings the element into view, but the element position is
not vertically center. When the document must be scrolled, the element
is located at the top

The infamous and often unnecessary CS0165 compiler error
Why? Why is the commented out first line below improper? The
overabundance of caution is the only thing I can figure. Not a big
deal, but strictly speaking unnecessary as the program should work
with this error.
RL
// char[] myCharacterArray; //gives: error CS0165: Use of unassigned
local variable
char[] myCharacterArray = new char[3]; //you must instantiate to avoid
this error
try
{
//do stuff here like...
char[] myCharacterArray = new char[3];

What TypeCode to return when implementing IConvertible GetTypeCode()
When i implement IConvertible GetTypeCode() which TypeCode would i
return?
TypeCode.Object if it is implemented in a class?
What in case if it is implemented in a struct?
In general i don't know what IConvertible GetTypeCode() is used for.
Can someone explain this to me? The examples i found in the msdn and
the web are not helpful.
Lets consider the unlikely case where i have an object that can best
be represented as a boolean value. Would i then return
TypeCode.Boolean to indicate that a conversion to a boolean value
among the type codes represents the object best?

Add a WPF form inside a dll in FW4
Hi all,
I have an application which is running with a dll (VS 2010, FW4 too).
I want my app to use WPF. That's OK.
But I also want my dll to provide a messagebox, made with WPF.
I can add in the dll a classic window form, but I didn't find how to use WPF
inside the dll. I just can add a WPF usercontrol.
Any help will be appreciated.

How to sort List<...> -- created using LinQ?
I found a nice LinQ function for GetFiles with multiple search patters
(multiple file types -- *.jpg, *.bmp, *.gif). This seems to work nicely
except that my list of files has an alphabetical ordering like
a1.jpg
a2.jpg
a1.bmp
a2.bmp
b1.jpg
b2.jpg
b1.bmp
b2.bmp
...
and the routine is listing/sorting all the .jpg's first and then the
.bmps, .gifs.
a1.jpg
a2.jpg
b1.jpg
b2.jpg
a1.bmp
a2.bmp
b1.bmp
b2.bmp
In windows explorer the files are listed/sorted by filename
alphabetically as desired.
a1.bmp

InvokeRequired? (multithreading)
It looks to me like InvokeRequired() is returning an unexpected

I have a multi-threaded app, and know it's a good idea to put all

this class, I print out the value for
Thread.CurrentThread.ManagedThreadId.
In all of the functions in my class, I have the same structure:

SOS,how to load a invalid or damaged .gif file to create Image Object.
hi everyone.
my question is this:how to load a .gif image file that is invalid or damaged
image format?
Notice,I want to load the invalid damaged image file to operate it.
my code is below,but all of they are not correct.
--------
1.Image.FromFile(fileName);load from a file directly,it throws a
OutOfMemoryException.In msdn,it's mean the file is a invalid image format.
2.Image.FromStream(stream);load from stream,it throws a ArgumentException.
--------
ps:IE and Google Picasa can load and display the damaged .gif file correct.

Why is not my event handler called when doing serialization resp deserialization
Hi!
Below is a complete rather easy program to understand that using a
CustomFormatter that is defined here.
What I don't understand in this program is why my four event hander are not
called. According to the documentation they should be called.
This one should be called before serialization.
[OnSerializing]
public void OnSerializingthisthod(StreamingContext context)
{
var2 = "This value went into the object just before serialization.";

and this should be called after serialization

Newbie : interface and eventargs
Hi all,
I use an interface to expose a class (within a dll). I also have a factory
that provides objects (here : Profile), using the factory.
It's running fine.
In these Profiles, I have Events. That's running fine too.
The problem I can't solve yet is with the EventArgs, which is specific to
the Profile class. In the event code (listener), I have the sender and the
std eventargs object.
I can't cast it. I suppose because the specific eventarg object isn't
exposed anywhere in the interface.
So how can I expose it, to be able to cast and to use its specific functions

Granting admin priveleges to a process started from a C# app

I wrote a C# GUI application that I use to install, uninstall, start, and
stop arbitrary Windows services. Although I would like to have handled all

do this on the Internet and I could never get it to work properly. As an
alternative I decided to merely use the C# code as a GUI wrapper around

Form becomes disabled/text invisible
Hi,
I have a class that inherits from Form. It's pretty simple; it
displays text. I have multiple of these, which get constructed
dynamically.
Unfortunately, if I click on one of these Forms, it becomes disabled,
and the text inside of it is no longer visible (the scroll bar is no
longer visible, etc.). In fact, it causes the rest of the windows to
become disabled as well.
It's as if the application has become too busy to maintain the Form's
visibility.
The application is multi-threaded.
What's going on? Thanks.

Virtual methods and late binding
hi
1) One definition of binding is that it is the act of replacing
function names with memory addresses.
a) Thus I assume early binding means function calls are replaced with
memory addresses during compilation process, while with late binding
this replacement happens during runtime?
b) Why are virtual methods also considered early bound (thus the
target method is found at compile time, and code is created that will
call this method)? As far as I know, with virtual methods the call to
actual method is resolved only during runtime and not compile time?!
2) Assume:

CTE Infinite Recursion
I have a situation where you can have an infinite recusion.
There is an issue where editing a page could cause infinite recursion. This
would happen if a distribution folder were put into itself. It would also
happen if you put folder "A" into folder "B" where folder "B" is in any of
the folders contained in any of the folders found in folder "A". A little
convoluted sentence but that is the problem.
A is in B and B is in C
If you put A into C then C will eventually point back to itself and you the
recursion will continue on

the customer orders in question.
So far so perfect..
But now add in the designer's DataContext, otherwise, it is not in the

Binary Serialized file much larger than expected

I have a class which has 6 automatic properties (6 x 8 bytes). This
means the total size of the class is 48 bytes. I have 15000 of these
in a generic List. When I serialize these to disc using the

closer to 48 * 15000 / 1000 = 720kb.

tables are varchars - one is varchar(50) and the other is varchar(36).
The Error I am geting is:
Conversion failed when converting the varchar value 'Clartia, MD (ALCM-FT)'
to data type bit.
The first row does happen to be a 1 but the type of r.LastName is
varchar(36) and u.LastName is varchar(50). Also, if I run the query without
the UNION and only use one SELECT it works fine with both SELECTs.
The one with the error is:

Boolean to String
Hello,
I am querying a XDocument as follows:
Boolean test = true;
IEnumerable<XElement> test1 = _albums.Root.Elements("Album").Where(a
=> a.Element("Active").Value == test.ToString());
IEnumerable<XElement> test2 = _albums.Root.Elements("Album").Where(a
=> a.Element("Active").Value == "true");
The first one where I use test.ToString() I get an empty enumeration.
On the second one where I use "true" I get 4 items.
What am I missing?
Thanks,

A better way of constructing a LINQ query
Hi folks,
I�ve got a LINQ query that filters out items in a database that begin
with a number. It looks like this:
char[] numbers = new char[] { '0', '1', '2', '3', '4', '5', '6', '7',
'8', '9' };
var result = (from i in Items
where numbers.Contains(i.Name[0])
orderby i.Name
select i).ToList();
Now this works, but I�m sure there must be a more efficient way of doing
this. Can anyone suggest a way that I can do it in a more efficient manner?
Cheers,

Accessing at runtime nested method's parameters values
Hi all,
I have some C# code with nested method call and I would like during runtime
to log on different level the values of method parameters (just like VS
offers Debug-> Windows->Call Stack). Is it possible because StackTrace class
does not seems to offer support of accessing parameters values, it support
just paremeter types and names ?

Hi!
I'm reading a book and and it says the following

If I look at the class XmlSerializer I can't see that this class is

RSS live feed
Hi,
I want to make an update check for some software and use RSS for that
(because it=92s on sourceforge.net and they have an RSS stream for the
directories).
Off course Google was my friend while looking for some code to read
RSS, but there=92s one thing I cannot find (not even on codeproject.com
or within source code of projects on sourceforge.net).
How can I make the RSS reader follow the RSS feed live? Is there an
event that I can use or something like that? Or do I have to use a
timer every second for instance? Or is there some code available to
just listen to the RSS stream

when to use soap and when to use xml
Hi!
I'm reading in a book and it says the following.
"Use XML serialization when you need to exchange an object with an
application that might not be based on the .NET Framework, and you do not
need to serialize any private members."
In the book it also says the following.
"Use SoapFormatter when other application might read your seriazed data and
when sending data across a network SoapFormatter also work reliably in
situations where you could choose BinaryFormatter."
So according to these two text sections I can use whichever of SoapFormatter

one major disadvantages with the binaryformatter is that you don't know what you have serialized
Hi!
You have three methods to use when serializing an object and these are:
1.BinaryFormatter
2.SoapFormatter
3.XML seializing
One major disadvantage with the BinaryFormatter is that you must document
exactly what you have serialize because if you don't you haven't the
slighest idea what you have serialized except text members.
If you use XML to serialize you can see exactly what you have serialize.
If you use XML to serialize insted of BinaryFormatter you will have much
greater files and the perfermance will be much slower then BinartFormatter.
So its probably best to us

LINQ: Select records but enforce one field to be unique
When selecting records by forcing one field to be unique, is it
necessary to use the .Distinct(...) function with an external
comparator?
EX: Say you had a list of purchase records...multifields. You want to
get -just- a list of people who had bought items. The 'purchaser'
field must be unique, so you don't just get back the entire list, but
you want to retrieve all fields in the record, so you can't just use
..Distinct(). (with no args)
I've seen examples that require coding an external class, creating an
instance, then passing that object to .Distinct(...) but this seems

The NonSerialized attribute
Hi!
The NonSerialized attribute has this text as part of its documentation.
"Indicates that a field of a serializable class should not be serialized.
This class cannot be inherited."
But this attribute has also another meaning and that is the following.
If you for example has serialized an object that contains a name field of
type string and than
add this Nonserialized attribute on the name field before deserializing the
file with the object within then this will happen.
The app will not read this name field into the deserialized object so the
object will not contains any nam

XML and Repository
Hello,
I created a few Repositories to manage some XML files.
Since the repositories share the same files I wanted all to work under
a same session (Unit Of Work Pattern).
So the Context, that implements ISession, contains a field _model that
contains all the XDocument requested by the repositories.
A repository can request a XDocument by using the Context Register
method.
If the file does not exist in model then it is loaded and returned. If
exists then it is only returned.
The change submission runs with session.Commit() which saves all XML
files.

BinaryFormatter
Hi!
Is it any advantage to use one over the other between these
two.
IFormatter serializer = new BinaryFormatter();
or
BinaryFormatter serializer = new BinaryFormatter();
If I have this
FileStream saveFile = new FileStream ("MyFile.bin", FileMode.Create,
FileAccess.Write);
serializer.serialize(saveFile, myObjectToSerialize);
saveFile.Close();

can every object be serialized even with referenced object within in a complex scenario
Hi!
If I have an object A that reference B and object B reference C
and a lot of built-in types and some user defined struct will object A be
able to be serialized to a file ?
My second question: Does it exist object that can't be serialized ?

Visual Studio 2010 RC
I've not used any RC version before. Some insight on this would be appreciated:
1. How long does a RC version carry out working?
2. What happens (are the options) when it stops?
3. Can it be uninstalled without adverse effects on earlier version of VS?
Thanks.

Some more about serialization
Hi!
I'm reading a book from Microsoft Press(MCTS). It says
*If you just needed to store a single string in a file, you wouldn't need to
use serialization
you could simply write the string directly to a text file. Serialization
becomes useful when storing more complex
information, such as the current date and time. As the following code sample
demonstates, serializing complex objects is as simple as serializing a
string."
Can anybode tell me the reason why to use serialization when I want to store
current date and time as the text above claims
when it's even simpler to store

Print PDF files with margins cut
If I print a pdf file with the source listed below, print out with the
trimmed edges. In fact I get a technical drawing with the missing
information.
The same results if I print from explorer context menu.
If I open the pdf file with Acrobat and do printing, the printed sheet is
correct.
How do I properly print the entire PDF file through code?
Thanks

about understanding serialization and the serializable attribute
Hi!
Assume I have a collection of Person object in generic class list List<T>.
List<Person> myList = new List<Person();
When I want to serialize this collection myList the Person class must have
the serializable attribute.
I know that the List<T> class also has this serializable attribute otherwise
it will not work.
Now to my question what I store is bunch of Persons objects stored in a
collection List<T> but why
must this List<T> class has this serializable attribute.
I don't fully understand that. I can easily understand that the Person class
must have this serializable at

how to change the registry settings of another user
Hi,
As part of a semi automatic installation and setup of a host I would
like to create one administrator account and one ore more (non
administrator) user accounts (without passwords)
Then I would like to start a script as administrator and change some
global and some user specific registry entries.
I have problems to modify the settings of another user whle being
administrator.
The registry entries don't exist). It seems I had to load some 'hive' to
be able to access somebody else's registry
I did my first tests not with C#, but with python and_winreg32,
but could

about isolated storage
Hi!
Is it anyone that has been using isolated storage and found they have been
useful ?
If yes can you give an example when they have been useful.
They most certain is good to use at some occasion but this occasion will
probably never occur.
For me it seems that it one of these feature that exist in .NET that are
used very rarely

Interface in Property
Hello,
I have a class Parent. What is the difference if a property is an
interface or a class? For example:
public class Parent {
public PA Pa { get; set; }
public IPA Ipa { get; set; }
}
Where PA is:
public class PA {
public String Name { get; set; }
}
And IPA is:
public interface IPA {
String Name { get; set; }
}
Thank You,
Miguel

what is the size of the internal buffer of fileStream
Hi!
If I use a filestream connected to a data storage like this program example
shown here. The data will be written to the data storage when the internal
buffer is full. So I just wonder what size is it on the internal buffer ?
I mean the actual write to the data storage will be done in chunks of some
size to increase the performance.
string overview = "Most commercial applications, such as...";
FileInfo fileStore = new FileInfo("Overview.txt");
FileStream conduit = fileStore.Create();
byte[] encodedOverview = new UTF8Encoding(true).GetBytes(overview);
conduit.Write(encodedOver
