Thanks Mr.Senthil,now it works fine but it doesn't returns the correct output value.
>>Code:
[DllImport("dll.dll")]
static extern int addition(int a,int b);
[DllImport("dll.dll")]
static extern IntPtr functionname(string value);
string s="codeprojectiscool";
string output;
int a = addition(3,4);
IntPtr normal;
normal=functionname(s);
output=Marshal.PtrToStringAuto(normal);
MessageBox.Show(a.ToString());
MessageBox.Show(output);
>>Input:
s="codeprojectiscool" //Initialized at design time itself
>>Output:
normal="123469904"
output="佃䕄剐䩏䍅䥔䍓住L﷽﷽" //error not correct output
but i should get the output="codeprojectiscool"
Thanks

hi everybody,
i have a class wich, i try to serialize. in this class i have a string value wich, i want to serialize in a CData section.
Code:
[XmlRootAttribute("result", Namespace="uri:Praxis-edv.de/XML/ResponseSchema.xsd")]<br />
public class GenericResultObject : IGenericResult<br />
{<br />
...<br />
<br />
[XmlAttribute("CommandName", Namespace="uri:Praxis-edv.de/XML/ResponseSchema.xsd", Form = XmlSchemaForm.Qualified)]<br />
public string CommandName<br />
{<br />
...<br />
}<br />
[XmlAttribute("State", Namespace="uri:Praxis-edv.de/XML/ResponseSchema.xsd", Form = XmlSchemaForm.Qualified)]<br />
public GenericResultState State<br />
{<br />
...<br />
}<br />
[XmlAttribute("Type", Namespace="uri:Praxis-edv.de/XML/ResponseSchema.xsd", Form = XmlSchemaForm.Qualified)]<br />
public string TextType<br />
{<br />
...<br />
} <br />
[XmlText(typeof(string))]<br />
public string TextResult<br />
{<br />
...<br />
}<br />
[XmlIgnore]<br />
public System.Type Type<br />
{<br />
...<br />
}<br />
[XmlIgnore]<br />
public object Result<br />
{<br />
...<br />
}<br />
public string ToXml()<br />
{<br />
...<br />
}<br />
public static GenericResultObject GetFromXml(string Xml)<br />
{<br />
...<br />
}<br />
}
Has anybody an idea how i can serialize the value TextResult in a CData section??
thank you.

Use [XmlCDataSection] attribute instead of XmlText and there you go.
Public Shared Function SerializeObjectToXML(ByVal input As Object, ByVal type As System.Type) As String
Dim returnXML As String = String.Empty
Dim serializer As New XmlSerializer(type)
Dim writer As New StringWriter
Try
serializer.Serialize(New XmlTextWriter(writer), input)
returnXML = writer.ToString()
Catch ex As Exception
Debug.WriteLine(ex.Message)
Finally
writer.Close()
End Try
Return returnXML
End Function

thanks for your answer, but it dosn't work. If i use [XmlCDataSection] i get the errormessage "The type or namespace 'XmlCDataSection' could not be found." I guess i forgot to say, that i programming in C#.
In C# there is no XmlCDataSection object in the 'System.Xml.Serialization' namespace.
Do you have any other idea how i can get this serialized?

Its under System.Xml

Hello,
I am trying to override the ProcessCmdKey method, and I want on Enter key,
SendKeys.Send ( )
to send back the NewLine key, or something that will allow the cursor to jump to the new line in the richTextBox. What should I put within the brackets?
Thank you.

How convert from "ushort a" to "short b" when a>32768
|
|
|
|
|
You can just cast it, "short b = (short)a;", but it may not be what you want.

Don't use shorts - use ints

It's idea. Thanks Darryl Borden

Why dosn't compile this "short[] arrOfShort= new short[]{0xFE00,0xE080}"?
|
|
|
|
|
A short is 16 bits signed. This means it goes from -32,768 to 32,767. Use ushort instead.

I can't. I must know sign 
|
|
|
|
|
are you intending to use the values in your code sample as negatives? IF so you might need to rewrite them with the sign explicitly. If they're supposed to be postive values you'll need to use an int since short ranges from -0x8000 to +0x7FFF (negative values are encoded in the upper half of the 0-FFFF range).

hi,
Could anyone tell me how to setup a sockets to listen to a specific port for anytype of connection both tcp or udp.
The code i use for the moment is:
ServerSocket = new Socket(AddressFamily.InterNetwork,SocketType.Raw,ProtocolType.IP);
IPEndPoint ipLocal = new IPEndPoint (IPAddress.Parse(GetIp(GetInterface())),GetPort());
// Bind to local IP Address...
ServerSocket.Bind(ipLocal);
// Start listening...
ServerSocket.Listen(50);
// Create the call back for any client connections...
ServerSocket.BeginAccept(new AsyncCallback (OnClientConnect), null);
this gives an error at the beginaccept method
thx for the help

Hi,
Try this:
int port = 9090;
// Initializaing the socket object to handle client requests, of type TCP on the port '9090'
Socket server = new Socket(AddressFamily.InterNetwork, SocketType.Stream,ProtocolType.Tcp);
IPEndPoint localEP = new IPEndPoint(IPAddress.Any, port);// accept only on that port.
server.Bind(localEP);
// The server can accept up to 50 client's at the same time.
server.Listen(50);
However, In order to differintate your client's from other application's that might use the same port and TCP, you should define a communication protocol, such as:
// Client send 'I am a client' , and the server then check that( either continue with the socket or destroy it).
I hope I get your question.
Kind Reagrds,
Mohammad

I am trying to work on a simple RSS reader. I would like to parse the pubdate field and determine the date. I know I can use System.Timer.Parse and put the value into a DateTime field. The problem is that I have seen the date in four format:
Tue, 16 Aug 2005 06:53:00 GMT
Tue, 16 Aug 2005 06:53:00 +0700
Tue, 16 Aug 2005 06:53:00 -0700
Tue, 16 Aug 2005 06:53:00 0700
I can search for the + and - and eliminate this character and the character following. I believe passing in GMT might work. But I am unsure how to handle something like the last example. Although it is not valid, it is something that will have to be handled. I don't want to code it so I automatically delete the last four numbers. My goal would be to come up with a universal way to handle all four. Does anyone have any suggestions/examples on how I can handle this programmatically? Any suggestions on handling the last three generically?

Hi, All, I've just started with C#, and now i'm working on the utility which downloads files from internet using https://. That's how i'm trying to get response:
WebRequest request = WebRequest.Create(strUrl);<br />
request.Method = "GET";<br />
request.PreAuthenticate = true; <br />
request.Credentials = CredentialCache.DefaultCredentials;<br />
<br />
WebResponse response = request.GetResponse();
It's says in the WebRequest class description, that it doesn't matter what protocol used, Http or Https, but there's an exception:
TrustFailure. 
Help, please, thanks for your time.

Hello,
Is there a way, when user clicks on the tab, to make this (active) tab to change colour, but only the tab itself, and not the whole page.
Thank you.
