I have created a class that inherits from ListView and a class that inherits ListViewItem and implements IComparable. If I put the items in an ArrayList and Sort the items are sorted correctly, but when i try to use Sort in the ListView it doesnt do anything. I´ve tryied invoking the sort part in the listview but no that doesnt work. I do not want to create a class for the sorting part so i thought that IComparable only on the objects in the collection would allow me not to modify the collection. Is there something im missing???

I use TCP Client class in the C# client program to connect to the server. I use the accept method in the c-written server to accept the incoming socket connection.

I have created a client in C# and a server in C. The Server is run on a linux computer and client on Windows. When the client tries to connect it fails. I have tried modifiyng the server to run on windows, and I am able to establish the connection between two windows computers. It also seems to work connecting a linux version of the client to the server on linux. But it doesn´t work connecting a c# version on windows to the c server on linux.

I seem to be having a problem with threads. I have modified the main function, so that i can run one application first, then when it disposes itself it will jump to the next line in the main function and finally i run the second application. I get errors with window handlers and controls not showing any graphics although i have invoked them. Am i missing something important here? [STAThread] static void Main() { try { Client c = new Client(); GameClient g; Application.Run(c); while(!SHUTDOWN) { if (!SHUTDOWN) { g = new GameClient(c.connection.Socket,c.connection.Username,c.connection.Table,c.connection.Users); Application.Run(g); Thread.Sleep(1000); //c = new Client(); //c = new Client(c.connection.Socket,c.connection.User); //Application.Run(c); SHUTDOWN = true; } } } catch(Exception ex) { MessageBox.Show("Client.Main " + ex.Message); } }

I get this error "DragDrop registration failed" when setting the AllowDrop property in a control. Im accessing a control from a different thread than the one that created the control. I use invoke when adding and removing,, the problem is i dont know if i have to invoke the dragdrop event or how it should be done.

I wish to jump from running the main form Form1 to run my Form2. I want my Form2 to dispose Form1 and continue to run as the main form. I have excperienced som difficulty in doing this as when Form1 is disposed it will close Form2 even if i have set the reference in Form1 to acces Form2 to be null. I believe its because Form1 is running the main thread, is it possible for me to create a similar thread in Form2 to overtake the main thread.

I get an exception in the last line, ExecuteNonQuery. It tells me there is something wrong with the SQL command, although this same command works fine within Access. I have tried this code with insert instead and it works. myConnection = new OleDbConnection( "Provider=Microsoft.Jet.OLEDB.4.0;Data Source=alfapet.mdb"); myConnection.Open(); using(myConnection) { OleDbCommand com = new OleDbCommand( "UPDATE userinfo SET Password='"+newPass.Pass+"' WHERE Name='"+user.Name+"' AND Password='"+oldPass.Pass+"'", myConnection); int i=com.ExecuteNonQuery();

I have a problem stopping the server process. Everything seems fine when i stop my multithreaded server, no exceptions when i shut down the application. But the server program wont stop executing. I cant find any more threads that i have forgot to abort. Still if i try to abort the CurrentThread in the end of the program i get an AbortException that cant be handled by the application. Is there something else i can try? Michelangelo
