I have the following string "\1 tag1 \2 tag2 \3 tag3", how do I declare this one in C#?
(the \1 \2 \3 are special characters)

Try
string st = "\\1 tag1 \\2 tag2 \\3 tag3";
or
string st = @"\1 tag1 \2 tag2 \3 tag3";
Best regards, Alexey.

Thanks, but this is local authentication. If use this way, at server you can receive more information for client user, but you will not know this information, that sent from valid user or not

You said all your machines are in an Active Directory domain. The WindowsIdentity is not local to the machine when in a domain environment. Unless, of course, the user picked the local machine as the domain name when he/she logged in.

Example:
User A and user B in domain, they is authenticated. User A run a app client, if he send information about A then no problem, but he use infomation of B to send to server. B is authenticated, so server accept request.
I want server only accept when A send information of A? Do you think?

Now you've got a problem that ha snothing to do with Windows Authentication. This is a data security problem specific your data model. If anyone can impersonate anyone else simply by typing information into a TextBox, you have to implement something to prevent this. But, what and how you do this is entirely dependant on your data model and requirements.
Have you looked at the properties of the WindowsIdentity class?

MailMessage mm = new MailMessage();
mm.From = "your mail address";
mm.To = "Other mail";
mm.Subject = "mail title";
mm.BodyFormat = MailFormat.Html;
mm.BodyEncoding = System.Text.Encoding.Default;
mm.Body = "Your mail text";
mm.Fields.Add("http://schemas.microsoft.com/cdo/smtpauthenticate","1");
mm.Fields.Add("http://schemas.microsoft.com/cdo/sendusername","yourname");
mm.Fields.Add("http://schemas.microsoft.com/cdo/sendpassword","yourpwd");

I am involved in a project whereby I have to use a methods from a Win32 dll. There are two methods for which I can't write signature in C#
I have even tried using p/invoke wizard, but it didn't gave the right answer.
The C/C++ declaration for these methods is
BOOL __stdcall CodecStart
(int hRadio,void __stdcall (*CallbackFunc)(void *),void *CallbackTarget); and
DWORD __stdcall CodecRead(int hRadio, void *Buf, DWORD Size);
I would highly appreciate if any2 can suggest the signature that I can use in C#
o O º(`'·.,(`'·., ☆,.·''),.·'')º O o°
»·'"`»* *☆ t4ure4n ☆* *«·'"`«
°o O º(,.·''(,.·'' ☆`'·.,)`'·.,)º O o°

What is CallbackFunc? I've never seen that type before. If it's a custom type, you might be better off building a C++/CLI dll that calls the method for you. You can then make your C++/CLI dll function call be public, thus allowing other .NET languages like C# to call the function as if it were native .NET code.
void* is similar to object; it can be used to store many different types. You'll need to first know what is expected before you can pass in something for void*.

CodecStart() takes a pointer to a callback function, the C# equivalent is a delegate. However, since the other DLL is a Win32 DLL, I don't know if it's going to work if you pass it the address of a managed code function.

I a calling an API method which requires passing the reference to an array as parameter. The problem is with that parameter
The actual function is
BOOL __stdcall G3BlockScan(int hRadio,DWORD *Freqs, int Count,int StopSquelchRaw, DWORD FeedbackTime,HWND WinHandle,DWORD Msg);
Here Freqs is an array whose contents are mofied by the The API function call.
I have wrapped this function in C# as follows..
[DllImport("wrg303api.dll")] <br />
public static extern bool G3BlockScan(int hRadio, <big>uint [] Freqs</big>, int Count,int StopSquelchRaw,uint FeedbackTime,IntPtr WinHandle,uint Msg);and the function call is like this .....
..... some code.....<br />
uint[] Freqs = new uint[1001];
..... some code....<br />
if (!clsApiWrapper.G3BlockScan(radioHandle, <big>Freqs</big>, 1001, 256, 100000, pointer,Msg))<br />
MessageBox.Show("The block scanning failed to start", "WiNRADiO - Error Message", MessageBoxButtons.OK, MessageBoxIcon.Error); <br />
..... some code ....But now when I run the app it doesn't change the contents of the array. so I believe I need to pass the reference of the array to the function. And if I change the code like this to pass the reference of the array
[DllImport("wrg303api.dll")] <br />
public static extern bool G3BlockScan(int hRadio, <big>ref uint [] Freqs</big>, int Count,int StopSquelchRaw,uint FeedbackTime,IntPtr WinHandle,uint Msg);<br />
<br />
..... some code.....<br />
uint[] Freqs = new uint[1001];
..... some code....<br />
if (!clsApiWrapper.G3BlockScan(radioHandle,<big>ref Freqs</big>, 1001, 256, 100000, pointer,Msg))<br />
MessageBox.Show("The block scanning failed to start", "WiNRADiO - Error Message", MessageBoxButtons.OK, MessageBoxIcon.Error);
Now when I access the Freqs array after the method call I encounter a strange behaviour.. The size of Freqs array is reduced from 1000 to 1.
I can't figure out what is going wrong.
Can any1 plz suggest what to do.

Hello all...
I want a method to embed an executable file (exe) in my application which is written in c# .. And I want a method to launch this executable after compiling my application without saving the embedded exe in a file.
And if it's possible I want a sample source code for an exe password protection program that is wrapping the exe directly.
Thanks in advance.

Is this embedded exe a .NET executable? If so, you can use System.Reflection.Assembly.Load method and pass it the byte[] of the assembly, IIRC.
If this .exe is not a .NET assembly, I don't think you'll be able to launch it without writing it to disk first.

Thank you very much for your quick response. But unfortunately the .exe file isn't a .NET assembly.

I made objects By 3D Max and I want to use these objects in Open GL...

I Appreciate any help

Well, firstly, you're going to need to render a scene in OpenGL using C#. Since OpenGL is native code rather than .NET, you'll need some bindings/wrapper to use OpenGL in C#. One such binding is the Tao OpenGL bindings[^]. You can use that to program OpenGL in your C# code.
In order to load files from 3dsMax, you'll need some library that loads files exported from Max. You can code one yourself or more preferrably, find an existing one. 3dsMax can save to .max files which are proprietary and closed. .3ds files can be exported from Max, and there are many well known .3ds file parsers which can parse out a .3ds file, read in the vertices, faces, and textures, then throw those together into a DirectX or OpenGL scene. One such .3ds importer for OpenGL is available here[^].
