Hi,
I'd like to know why after calling
_tcpClient.Client.LingerState = new LingerOption(false, 0);
_tcpClient.Client.Shutdown(SocketShutdown.Both);
_tcpClient.Client.Disconnect(true);
, when I try to connect again, I get a Socket already connected exception.
I dont know what else to try, please help!

pease gime me date time picker(dtp)surce code for send values oledb database

Please don't double post. Your question is unintelligible. You just pass a datetime to the database, the datetime picker is irrelevant to the process.

Yes, and it is a simple process he is trying to do.

Hello all,
I wonder if the following problem is possible in c#:
I have two classes named class1 & class2 both having two functions named func1 & func2. Although the function names are the same, what they do are different for two classes.
I want to declare only one object to use these functions.
In order to do what the following code portion does
class1 obj1 = new class1();
class2 obj2 = new class2();
if (selection == 1)
obj1.func1();
else if (selection == 2)
obj2.func1();
I need a shorter and smarter way i.e;
The above code is possible but it is too long. You should write if statements every time you want to call the functions. So I want to do this with a shorter code:
I have an object which is assigned to the obj1 or obj2 (which are declared as above) depending on the selection at the beginning of the program, then you can call the funcs just by obj.func1()
I dont want to write if statements each time i am calling the functions.
Declaring an object of type object is OK but this time you have to cast the obj which is of type object to class1 (or class2) each time you are calling the functions. So casting is a not a solution either. I think i am looking for something like "Permanent casting" (if exists of course)?
P.S : One of the classes may have extra funcs which the other doesnt contain so "Inheritance" is not enough 
Regards
Zafer

Create a base class, and two derived classes, then you can call the method, and it's different based on which type of class the instance is.

Thanks for your post Christian.
What if one of the classes have an extra func that the other class does not have. Is it possible to call that function in that case? Because as the object is of type baseclass I will not be able to see it.

Not unless you first check if it's that type, or define those methods in an interface ( which you would still have to cast to ). That's how inheritance works. You CAN define a method in the base class that doesn't do anything in the base class, and then does in derived ones.

Define an interface that has those two functions. implement that interface in both classes. cast the selected object to that interface.
public interface fred
{
void func1();
void func2();
}
public class class1 : fred
{...} etc
class1 c1 =...
class2 c2 =...
fred doer;
if (...)
{
doer = c1;
}
else
{
doer = c2;
}
doer.func1();
etc

Hi!
i am trying to copy nodes from one xml to another, i am doing a simple action, appending the first xml the node that i want from the other xml using the XmlNodeList(specific node).
I always get the error that this node belongs to another xml document:
"the node to be inserted is from a diffrent document content"
how should i do this copy??
Thanks

You need to create a new node and copy it into the new document, otherwise, the same node ( as it's passed by reference ) is in two documents, and this is verboten.

You must first Import the node from another doc to yours,you can do that using ImportNode method from from XmlDocumrent instance so it would be somewhat like this
and if you want to create a whole new coy of your node pass deep argument as true otherwise just the selected node would be impoterd not the childs
XmlDocument doc1 = new XmlDocument();
doc1.AppendChild(doc1.CreateElement("MyElement"));
doc1.Save(@"N:\doc1.xml");
XmlDocument doc2 = new XmlDocument();
<code>XmlNode importedNode = doc2.ImportNode(doc1["MyElement"], true);</code>
doc2.AppendChild(importedNode);
doc2.Save(@"N:\doc2.xml");
good luck

Hi
I have designed an application which creates and uses an encoded XML file as its database.Some times overnothng this file gets damaged. I put a backup service for this app to check the file every 20 seconds and if it finds errors in the file it will restore the backup.The point is sometimes althought the file is broken ,the backup service finds this file as correct.also the program continues working with the file untill it gets closed.After closing the program the problems raise I face a big loss in data.
Could anyone tell me what the problem is and why before closing the app the file seems to be correct but after closing the app file gets corrupted.
Thanks

Yes, the problem is bugs in your code. We can't really say more without seeing the code.

Hi,
This is my code:
<br />
System.IO.FileStream file=System.IO.File.OpenWrite(_fileName);
System.IO.MemoryStream ms=new System.IO.MemoryStream();
dataset.WriteXml(ms);
ms.Position=0;<br />
byte[] buffer=new byte[ms.Length];
ms.Position=0;<br />
ms.Read(buffer,0,buffer.Length);
ms.Close();<br />
file.Position=0;<br />
file.SetLength(0);
buffer=System.Text.Encoding.UTF8.GetBytes(Encrypter.EncryptData(System.Text.Encoding.UTF8.GetString(buffer)));
file.Write(buffer,0,buffer.Length);
file.Close();
Just one process can write on main file,other processes like backup process may read this file.

Hi all,
In VB.Net
Dim strTemp as string
strTemp = "today is " _
& " Saturday "
How to do the above in C#.Net?
Thanks

If you can;t work that out, you should be doing a very basic tutorial in C#, or buying a book.
string strTemp;
strTemp = "today is Saturday";
strTemp = "today is " +
"Saturday";
string temp = "today is Saturday, and Microsoft no longer recommends Hungarian notation";
Note, C# doesn't have the stupid rule where you need a special character to show code goes over two lines.

Excellent reply!
|
|
|
|
|
Or even:
string today = "Saturday" ;
string temp = string.Format ( "Today is {0}" , today ) ;
|
|
|
|
|
Yes, using string.Format is good. Seems I've been going down that road lately
