ASP.NET is a framework. C# is a language that can be used to write ASP.NET applications. Are you asking how to communicate between the ASPX page and the code behind?
If not then you really need to explain better because I don't understand what you are asking.

the problem is this. some people must use aspx web page to chat. and some people must use a windows application like msn messenger. for exmple, i will use msn messenger to chat with you, and you must use an aspx web page to chat with me. maybe this is more clear

It can be done, and the general practice is to have a central server with 2 types of client:
web: pings for new messages (possibly using AJAX)
windows: gets messages pushed to it from server.
Start with an example of a straight windows forms chat application - there will be plenty online - and build the web client when you are more knowledgable on cthe chat software.

Try this one.
If that doesn't work, you should search Google like I did for that link.

Can anyone help me with this error. It appears to happen when I try to create an istance of the UPnPDeviceFinderClass.
Creating an instance of the COM component with CLSID {E2085F28-FEB7-404A-B8E7-E659BDEAAA02} from the IClassFactory failed due to the following error: 80070422.
My application searches a LAN for uPnP devices, for some reason it works fine on most computers but there are a select few that I get the above error.
Freedom is the right to say that 2+2=5 if this is so everything else will follow.

...I would assume that you are using the 2.0 Framework? ...It has been suggested that that error is caused by a bug in the framework. There's a hotfix available here ...Apply it and see if your error disappears. If it does, come back and let everyone know. If it doesn't, then I'm out of ideas.

Hey Alaric_,
Your assumption is correct, I am using the 2.0 Framework.
I did install the update that you recommended, but it didn't change a thing unfortunately.
Thank you very much for your suggestion, at the minute I'm stuck between a rock and a hard place.
If anyone else has any suggestions I would be glad to hear them.

hello
when i compiling this code its appended allthe lines in one line..
I want to keep the file as it is and want to add comment where there is assemblyVersionInfo string...
String strPathToFile = "Put here the path to the .cs file";
System.IO.StreamReader sr = new System.IO.StreamReader(strPathToFile);
System.Text.StringBuilder strAllText = new System.Text.StringBuilder();
bool AlreadyCommented = false;
do
{
if(sr.Peek() == -1) break;
String line = sr.ReadLine();
if(line.IndexOf("AssemblyVersion") > -1 && line.IndexOf("//") > -1) AlreadyCommented = true;
strAllText.Append(line);
}
sr.Close();
if(AlreadyCommented) return;
System.IO.FileInfo fi = new System.IO.FileInfo(strPathToFile);
fi.CopyTo(strPathToFile + ".bak"); //backup copy of the old file
int posOfAssemblyVersion = strAllText.ToString().IndexOf("AssemblyVersion");
//Look for the closing bracket "]"
int posOfClosingBracket = strAllText.ToString().IndexOf("]", posOfAssemblyVersion);
string strComments = "//Put there the desired comments";
strAllText = strAllText.Insert(posOfClosingBracket, strComments);
System.IO.StreamWriter sw = new System.IO.StreamWriter(strPathToFile, false); //overwrites the original
sw.Write(strAllText.ToString());
sw.Close();
if you have any ans then plz reply as soon as
thanks

instead of strAllText.Append(line);
you might want to look at strAllText.AppendLine(line);
Have Fun

sealed class Class1
{
public int g=0;
}
class pan
{
Class1 d = new Class1();
}
i know i can't inherit the sealed class , but after instantiating the selaed class in another class , i am not getting the class name object.
eg after instantinating the class class1
Class1 d = new Class1();
in next line of code when i type the character d , the intellisence does not show the object d.
why this is happening ?

definitely it should work. For clarification try with some default sealed class in the .Net framework.
Check if you are trying to access the class from any methods or not.

class object are not appearing while i try to access the member functions of that sealed class
