Hi everyone,
I'm having a strange problem with unicode encoding in C# / Macromedia Flash, and I think I need a little explanation to make sure I understand WHERE is the problem. 
So, in C#, we have Encoding.UTF8 and Encoding.Unicode. Encoding.UTF8 will encode ASCII characters into 8 bits, and all other characters as 16 bits (accented characters, etc). On the other hand, Encoding.Unicode is actually UTF16 and will encode all characters into 16 bits.
The problem: latin small letter s with caron - š - with character code 0x0161. This letter is encoded into 0x6101 when using Encoding.Unicode or 0x0161 when using Encoding.BigEndianUnicode. However, when using Encoding.UTF8, this letter is encoded into 0xC5A1.
In Macromedia Flash, strings are apparently encoded using UTF8, as the base ASCII characters are encoded into 8 bits, but the small letter s with caron - š - is encoded into 0x0161.
So now I don't know why is it different in UTF8 in C#?
Any clues will be highly appreciated...

Thanks Mike, this makes sense! Now it seems that the Flash is actually using UTF-16 internally, not UTF-8. I will forward this to our Flash guy.
One more question - is there any easy and straightforward way to convert UTF-16 representation to UTF-8 representation of a letter?
[EDIT]I was thinking about an algorithm, or a simple script, not about the C# Encoding.Convert[/EDIT]
Thanks again!

Hopefully I got it right that you want to move the mouse cursor to a position, whose coordinates are given in two textboxes.
The following code snippet assumes that only numbers can be entered into both textboxes, cause otherwise the Parse methods might throw an exception.
int x = int.Parse(textBoxX.Text);
int y = int.Parse(textBoxY.Text);
System.Windows.Forms.Cursor.Position = new Point(x, y);

Hello C# developers,
I would like to send SMS via my c# code.I am planning to send SMS by using a web site.But how can I provide user name and password for this web site? do you have any sample code for this?
I have made some researches on MSDN web site and all the code samples were about Pocket PC programming.
Can anyone help? How can I do this?
Regards

I was thinking of creating a simple, specialised task manager. It seems quite easy to use the Diagnostics.Process class to get processes memory and CPU usage.
But I also need to get GDI and USER objects per process. Is there any similar class for that or is it performance counters or WMI I need to look into?

Yes, you do need to use performance counters for this.

Hi Heath,
thanks for your answer. I did look into the performance objects in PerfMon (I have a XP Home WS at home and a Win2K WS at work) and could not find any counters for the process object. Actually I could not find any counter for this. I have looked with exctrlst.exe and could not find any disabled counters.
So I have to ask if you can point me in the right direction on how to proceed:
1. Do I have to do something to add more counters to the process object (or they might just not are available in WS PerfMon).
2. Is there any other performance object I should look into (but I still want the count per process as in the Task manager).

If you can't find performance counters that suit your needs, you'll need to P/Invoke native APIs when appropriate, like GetPerformanceInfo or GetProcessMemoryInfo, both defined in psapi.dll on XP and newer. I recommend reading the native performance monitoring and Processes sections of the Platform SDK at http://msdn.microsoft.com/library[^]. The .NET BCL by no means provides a full set of diagnostic APIs for issues like this.

Through googling I later found that the easiest way was to use the GetGuiResources method in User32.dll. This provides the GDI and USER objects counters for each process.

Hello,
Is there anyone can help on how to access the windows (oulook) address book with the standard dialog. I need to get back name, company, phone number and fax number.
Thanks

In fact, the address book dialog I want to display is this used by Outlook when you click on "TO" button when you send an email. With this dialog you have access to your exchange address book and your personal adress book...

hi there !
i am doing a chat app with c#. i have used tcpclient and listener classes to send data across. recently i have encrypted
the data iam sending back and forth with rjindael encryption algorithm. when i did this iam losing some characters on the receiving end. it's sort of truncation. on both the server side and client i perform an asynchronous read with a buffersize of 5120. the sendbuffersize and receivebuffersize for the tcpclient are default which is 8192 bytes.
please tell me what is happening here and guide me.
thanks.

Have you tried calling Flush() on the encryption provider and/or the TcpClient stream after each write?

Hi reinux !
i am calling flush() after each call to write. thats already in place.
any more possiblities.
thanks.

Are you using a language with something other than 1 byte characters? You might be counting characters wrong. For example, say you're working with Japanese transmissions (2 bytes per character). Say there are 50 characters -- that's 100 bytes. But if you count characters rather than bytes, and you send only 50 bytes worth, you'll only get the first 25 characters across.
It's a rare mistake in C#, but it can still happen.
Hope this helps.

hey reinux !
thanks for that info man. i misunderstood my own problem. fixed it.
tahnks for your time. will post any questions i have in future on codeproject.
that was informative.

Hi,(new to programming)
I want to read xml data into an DataTable, but from what I've read you have to load it into a DataSet. Anyway, I was wondering if it was possible to end up with just a DataTable in the end with NO reference to the original DataSet? My attempt below still causes the error "DataTable belongs to another DataSet" if I try and load it into another DataSet. I can use the .Copy to stop this, but I'm wondering if it's possible to create a DataTable from a DataSet table that has NO reference to the original DataSet?
myDS_Options.ReadXml("options.xml");
myDT_Options = myDS_Options.Tables["Options"].Copy();
myDS_Options.Dispose();
thanks,
Ron

Did you try the Dataset property on the DataTable??
-You just have to change this

Hi,
I am new to .NET, so my apologies if this question is silly. I am wondering, is it possible to send an instance of a class/struct from server to client through remoting, when the class/struct is not defined on the client side?
I need to develop a server that will create user-defined types on the fly using Reflection.Emit, then return instances of these objects to the client. As these types are defined on the fly, there is no way of including the class definitions on the client application.
When I try to do this, I get the error
---
An unhandled exception of type 'System.Runtime.Serialization.SerializationException' occurred in mscorlib.dll
Additional information: Parse Error, no assembly associated with Xml key ...
---
This occurs despite using TypeAttributes.Serializable when creating the type :
TypeBuilder helloWorldClass = module.DefineType("UserType", TypeAttributes.Public | TypeAttributes.Serializable)
